Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in figure 1, the invention provides a multi-specification load synchronous fastening and unlocking mechanism which comprises a transverse connecting rod assembly 2 and a swing rod mechanism 3, wherein the swing rod mechanism 3 is driven by the transverse connecting rod assembly 2 to complete synchronous opposite/reverse motion, so that synchronous fastening and unlocking functions are realized.
As shown in fig. 3, the transverse link assembly 2 includes two links 21, the two links 21 are identical in length direction, that is, the two links 21 are parallel to each other, and at least one link 21 can move back and forth along the length direction thereof, so that the two links 21 can move toward or away from each other, while in order to avoid the two links 21 from being influenced by each other in the movement toward or away from each other, the two links 21 can have a smaller space therebetween, and the occupied space is smaller while satisfying the rocker mechanism 3.
As shown in fig. 4, the swing link mechanism 3 includes a plurality of swing links 31, the plurality of swing links 31 are divided into two groups, two groups of swing links 31 are respectively installed on two connecting rods 21, that is, each connecting rod 21 is installed with a plurality of swing links 31, and each swing link 31 can move up and down, left and right on the connecting rod 21, but when the swing links 31 move up and down, left and right on the connecting rod 21, the swing links 31 do not separate from the connecting rod 21; meanwhile, after the two connecting rods 21 are installed, under the condition that the two connecting rods 21 do not move towards and away from each other, the middle parts of two adjacent oscillating bars 31 in the two connecting rods 21 are hinged with each other, and here, the two adjacent oscillating bars 31 on the same connecting rod 21 are not hinged with each other, but the oscillating bar 31 on one connecting rod 21 is hinged with the oscillating bar 31 on the other connecting rod 21.
In practical use, because the upper ends of the swing rods 31 are limited by the connecting rods 21, when the two connecting rods 21 move in opposite directions, the two swing rods 31 hinged to each other swing around a hinge point, the swing rod 31 on one connecting rod 21 swings in opposite directions with the front swing rod 31 or the rear swing rod 31 on the other connecting rod 21 to form a clamping state, and at the moment, fastening of goods or ammunition can be realized, namely, loading of the goods or the ammunition is realized; when the two connecting rods 21 move oppositely, the two swing rods 31 hinged with each other swing by taking a hinge point as a center, the swing rod 31 on one connecting rod 21 swings oppositely with the front swing rod 31 or the rear swing rod 31 on the other connecting rod 21 to form an opening state, and then the goods or ammunition can be unlocked.
In the invention, the distances between two adjacent swing rods 31 on each connecting rod 21 are equal, and the loading of goods or ammunition can be realized only by matching the swing rods 31 on the two connecting rods 21, so that the ends of the two connecting rods 21 can be flush or staggered when the two connecting rods 21 are installed. Because the swing rods 31 on the two connecting rods 21 are required to be mutually matched to realize fastening and unlocking, when the end parts of the two connecting rods 21 are flush, the swing rod 31 does not need to be installed at the left end of one connecting rod 21, and the swing rod 31 does not need to be installed at the right end of the other connecting rod 21; when the end portions of the two connecting rods 21 are dislocated, the dislocated distance of the two connecting rods 21 is equal to the distance between two adjacent swing rods 31 on the same connecting rod 21, the swing rods 31 can be mounted at the left end and the right end of the two connecting rods 21, and the distance between the swing rod 31 at the end portion of one connecting rod 21 and the swing rod 31 at the end portion of the other connecting rod 21 is equal to the distance between two adjacent swing rods 31 on the same connecting rod 21.
As a further improvement of the present embodiment, the clamping portion of the swing link 31 is curved, the bending direction of the swing link 31 on the same link 21 is the same, the bending direction of the swing link 31 on one link 21 is opposite to the bending direction of the swing link 31 on the other link 21, so that when the two links 21 move in opposite directions, the swing link 31 on one link 21 and the previous swing link 31 or the next swing link 31 on the other link 21 are in a clasped state, and the fastening effect on goods or ammunition is better. It should be noted here that the clamping portion of the swing link 31 is one end of the swing link 31 which clamps the goods or ammunition after swinging around the hinge point, and the specific bending shape of the clamping portion of the swing link 31 can be adjusted according to the object to be fastened, for example, the clamping portion of the swing link 31 can be in an arc shape, a bending shape with a certain angle, etc., so that the same structural form can adapt to fastening and unlocking with different loads in the same shape; of course, in the present embodiment, the shapes of the clamping portions of the plurality of swing rods 31 on the same connecting rod 21 may not be completely the same, but the shapes of the clamping portions of the two swing rods 31, which are matched with each other and fastened to the same cargo, on the two connecting rods 21 need to be the same, and when cargo or ammunition with different shapes needs to be loaded, the swing rods 31 with the corresponding shapes can be replaced, so as to meet the loading requirements on different cargoes or different ammunitions.
Taking the goods with different external diameters as an example, if the overall length of the two connecting rods 21 is 2500mm after being installed, the number n of the goods which can be loaded and fastened in the invention is 5-14, and the relationship between the number of the goods which can be loaded and fastened and the diameter of the goods is shown in table 1:
TABLE 1 relationship between cargo quantity and cargo diameter
From the above, as the diameter of the goods is larger, the quantity of the goods loaded by the goods is smaller, the weight of the load is larger, and the response time and the locking torque of the goods are not changed; meanwhile, only 3 kinds of goods with different diameters are given, but in practical situations, under the condition that the load fixing requirement is met and the number of the loads is fixed, the types of the goods with different diameters which can be simultaneously loaded by the invention are 2-6.
As a further improvement of this embodiment, in order to prevent the pendulum 31 of one link 21 from slipping when cooperating with the previous pendulum 31 or the next pendulum 31 of the other link 21 to fasten goods or ammunition, a clamping pad may be disposed at the clamping portion of the pendulum 31, the clamping pad may be made of rubber or the like, and in order to enhance the friction between the clamping pad and the goods, an anti-slip texture may be disposed on the clamping pad.
As a further improvement of the present embodiment, each connecting rod 21 is provided with an installation groove 22, the length direction of the installation groove 22 is consistent with the length direction of the connecting rod 21, and the installation groove 22 simultaneously penetrates through the upper surface of the connecting rod 21 and the lower surface of the connecting rod 21, the number and the positions of the installation grooves 22 on each connecting rod 21 correspond to the number and the positions of the swing rods 31 on the connecting rod 21, and the width of the installation groove 22 is adapted to the thickness of the swing rod 31; meanwhile, in order to facilitate the installation of the swing rod 31, the threaded pin 23 is further installed in the installation groove 22, the length direction of the threaded pin 23 is consistent with the width direction of the installation groove 22, the upper end of the swing rod 31 is further provided with a long waist hole 33, the long waist hole 33 penetrates through the threaded pin 23, the upper end of the swing rod 31 is sleeved on the threaded pin 23, the upper end of the swing rod 31 can swing on the threaded pin 23, the swing rod 31 can also move up and down on the threaded pin 23, therefore, when the two swing rods 31 which are hinged with each other swing by taking a hinge point as a center, the upper end of the swing rod 31 can move up and down and left and right on the connecting rod 21, and the installation structure of the swing rod 31 and the connecting rod 21 is simpler.
As a further improvement of the present embodiment, the multi-specification load synchronous fastening and unlocking mechanism provided by the present invention further includes a limiting mechanism 4, the limiting mechanism 4 is used for limiting and guiding the reciprocating motion of the connecting rod 21, the limiting mechanism 4 is provided with two ends, each limiting mechanism 4 corresponds to one connecting rod 21, each limiting mechanism 4 at least includes one limiting block 41, when in actual installation, the limiting block 41 is fixed on the equipment for installing the present invention, for example, if the present invention is used on cargo transportation equipment, the limiting block 41 in the limiting mechanism 4 is fixed on the cargo transportation equipment; the limiting blocks 41 are further provided with sliding pins 42, the length direction of the sliding pins 42 is consistent with the thickness direction of the connecting rods 21, the two connecting rods 21 are provided with sliding grooves 24, the width of each sliding groove 24 is matched with the diameter of the corresponding sliding pin 42, the length direction of each sliding groove 24 is consistent with the movement direction of the corresponding connecting rod 21, the length of each sliding groove 24 is not smaller than the movement distance of the corresponding connecting rod 21, the sliding pins 42 are inserted into the corresponding sliding grooves 24 on the corresponding connecting rods 21, and through the matching of the sliding pins 42 and the sliding grooves 24, the opposite movement and the opposite movement of the connecting rods 21 are limited, and the up-and-down movement of the connecting rods 21 can be limited.
When the number of the limiting blocks 41 in the limiting mechanism 4 is multiple, the number and the positions of the sliding grooves 24 on the connecting rods 21 corresponding to the limiting mechanism 4 correspond to the number and the positions of the limiting blocks 41 in the limiting mechanism 4, so that each sliding pin 42 in the limiting mechanism 4 can be correspondingly inserted into the corresponding sliding groove 24, the limiting effect on the connecting rods 21 is better through the matching of the plurality of sliding pins 42 and the sliding grooves 24, and the two connecting rods 21 can move more stably in the opposite direction or in the opposite direction.
As a further improvement of this embodiment, the middle portions of two adjacent swing links 31 on two connecting rods 21 are hinged by a pin 32, so that the hinging between two adjacent swing links 31 on two connecting rods 21 is more convenient, and certainly, under the condition that the swing links 31 synchronously swing in the process of opposite or opposite movement of the connecting rods 21, the hinging between two adjacent swing links 31 on two connecting rods 21 can also be realized by adopting other manners. Here, the two adjacent swing rods 31 on the two connecting rods 21 refer to two corresponding and hinged swing rods 31 on one connecting rod 21 and the other connecting rod 21, the bending directions of the two swing rods 31 are opposite, the two swing rods 31 cannot be matched to fasten goods or ammunition, and the two swing rods 31 need to be matched with the previous swing rod 31 or the next swing rod 31 to fasten goods or ammunition.
As a further improvement of the embodiment, the multi-specification load synchronous fastening and unlocking mechanism provided by the invention further comprises a driving mechanism 1 for driving the two connecting rods 21 to move relatively along the length direction, and the driving mechanism 1 provides power for the two connecting rods 21 to move oppositely or reversely, so that the two connecting rods 21 are driven, and the goods or ammunition is fastened and unlocked.
As a further improvement of this embodiment, as shown in fig. 2, the driving mechanism 1 includes two adjusting seats 11, the adjusting seats 11 are shaft seats, when actually installed, the adjusting seats 11 are fixed on the equipment for installing the present invention, for example, if the present invention is used for cargo transferring equipment, the adjusting seats 11 in the present invention are fixed on the cargo transferring equipment; simultaneously, install two-way threaded rod 13 on two adjustment seats 11 jointly, two-way threaded rod 13 can rotate on two adjustment seats 11, the screw thread turning at two-way threaded rod 13 both ends is opposite, 13 one end of two-way threaded rod is forward screw thread promptly, the 13 other end of two-way threaded rod is reverse screw thread, and slider 12 is all installed with one end of two connecting rods 21, threaded hole has all been seted up on two sliders 12, the screw hole on one slider 12 and the screw-thread engagement of 13 left ends of two-way threaded rod, the screw hole on another slider 12 and the screw-thread engagement of 13 right-hand members of two-way threaded rod. When the bidirectional threaded rod 13 rotates, the two sliders 12 move in opposite directions on the bidirectional threaded rod 13 due to different thread directions at two ends of the bidirectional threaded rod 13, so that the two sliders 12 move in opposite directions or in opposite directions, and the two connecting rods 21 are driven to move in opposite directions or in opposite directions. Through adopting two-way threaded rod 13 to make two connecting rods 21 realize synchronous motion, it is more convenient not only to the drive of connecting rod 21, and makes the movement distance of two connecting rods 21 shorten relatively to the response to goods or ammunition fastening, unblock is faster, further improves load filling efficiency and system response time.
In the embodiment, a principle that the two connecting rods 21 are driven by the two-way threaded rod 13 to move oppositely is utilized to provide power for locking and unlocking, and when the lead angle of the two-way threaded rod 13 is less than or equal to 3 degrees and less than or equal to 40', the fastening or unlocking operation time is t = L/(2 multiplied by D multiplied by R), wherein L is the distance between the two sliding blocks 12, D is the thread pitch on the two-way threaded rod 13, and R is the rotating speed (revolution/second) of the two-way threaded rod 13. Assuming that the fastening or unlocking operation speed of the present invention is 1 revolution/second, the fastening or unlocking operation time of the present invention t = L/(2 × D × R), that is, the fastening or unlocking operation time of the present invention is 18s; meanwhile, according to the universal load weight, in order to overcome the frictional resistance, the driving force is generally less than 50N, and the locking torque is less than 12.5 N.m.
As a further improvement of this embodiment, the driving mechanism 1 further comprises a driving element for driving the bidirectional threaded rod 13 to rotate, and since the bidirectional threaded rod 13 needs to rotate, the driving element is a driving motor, and when the driving motor is installed on the equipment for installing the present invention, the manner for driving the bidirectional threaded rod 13 to rotate is simpler.
In the embodiment, a bidirectional air cylinder or a bidirectional hydraulic cylinder or a bidirectional electronic telescopic rod can be used to replace the bidirectional threaded rod 13, in this case, two sliding blocks 12 are not needed, the bidirectional air cylinder or the bidirectional hydraulic cylinder or the bidirectional electronic telescopic rod can be directly installed between two adjusting seats 11, the two connecting rods 21 are driven to move oppositely or oppositely by the extension and contraction of the bidirectional air cylinder or the bidirectional hydraulic cylinder or the bidirectional electronic telescopic rod, and the automatic fastening and unlocking of goods or ammunition can also be met. Certainly, in this embodiment, without considering the situations of automatic fastening and unlocking, a handle may be directly installed at one end of the bidirectional screw, and the handle is manually rotated to drive the bidirectional screw 13 to rotate, so that the two connecting rods 21 can move in opposite directions or in opposite directions, and since the rotation of the bidirectional screw 13 is transmitted to the connecting rod 21 and then moves linearly, the connecting rod 21 does not reset without external force after the bidirectional screw 13 rotates in place, and a locking structure for locking the bidirectional screw 13 does not need to be arranged under the situation that the bidirectional screw 13 is manually driven to rotate.
As a further improvement of this embodiment, the bidirectional threaded rod 13 is detachably connected to the driving element, so that the driving element is more conveniently connected to and detached from the bidirectional threaded rod 13, thereby facilitating the later maintenance.
As the further improvement of the embodiment, one end of the bidirectional threaded rod 13, which is far away from the driving element, is also provided with a square end head, so that the driving element is more convenient to connect with the bidirectional threaded rod 13, the driving element is convenient to replace in the later period, and the later-period transformation and upgrading are more convenient.
When goods or ammunition needs to be loaded and fastened, the goods or the ammunition is placed between the swing rod 31 on one connecting rod 21 and the front swing rod 31 or the rear swing rod 31 on the other connecting rod 21, the driving element or the manual driving bidirectional threaded rod 13 rotates forwards, when the bidirectional threaded rod 13 rotates forwards, the threaded hole in the sliding block 12 is meshed with the threads on the bidirectional threaded rod 13, the two sliding blocks 12 move oppositely while the bidirectional threaded rod 13 rotates forwards, the two sliding blocks 12 drive the two connecting rods 21 to synchronously and linearly move while the sliding pin 42 is matched with the sliding groove 24, the two connecting rods 21 move oppositely, and when the connecting rods 21 move oppositely, the upper ends of the swing rods 31 are limited by the threaded pin 23, so that the two swing rods 31 hinged with each other during the opposite movement of the two connecting rods 21 swing around the hinged point, the swing rod 31 on one connecting rod 21 swings oppositely to the front swing rod 31 or the rear swing rod 31 on the other connecting rod 21, a clamping state is formed, and therefore the fastening of the goods or the ammunition is realized, namely the loading and the ammunition is loaded and fastened.
When goods or ammunition loaded and fastened needs to be unlocked, a driving element or people drives the bidirectional threaded rod 13 to rotate reversely, when the bidirectional threaded rod 13 rotates reversely, the threaded holes in the sliders 12 are meshed with the threads on the bidirectional threaded rod 13, the two sliders 12 move oppositely while the bidirectional threaded rod 13 rotates forwardly, the two sliders 12 drive the two connecting rods 21 to move synchronously and linearly while moving through the matching of the sliding pin 42 and the sliding groove 24, the two connecting rods 21 move oppositely, and when the connecting rods 21 move oppositely, the two swing rods 31 hinged with each other while the two connecting rods 21 move oppositely swing by taking a hinge point as a center due to the limitation of the threaded pin 23 on the upper ends of the swing rods 31, the swing rods 31 on one connecting rod 21 swing oppositely to the previous swing rod 31 or the next swing rod 31 on the other connecting rod 21 to form an open state, and therefore the goods or ammunition can be unlocked.
