Description

Gunpowder structure

The present invention relates to a gunpowder gun structure; in particular, it relates to a gunpowder gun structure in which the force of each firing under continuous firing can be maintained to the maximum and the angle between the gun case and the gun body can be controlled.

According to this, the gunpowder nail gun is a nailing tool that uses the principle of gunpowder burst to push a nail rod to hit the nail body into a rigid target.

Since the firing power of the gunpowder nail gun is quite powerful, if the false firing action occurs when it is in the air (meaning that it does not collide with any physical target but is opposed to the void), the force of the nail body will inevitably cause serious damage to personnel and objects. And damages have caused great safety concerns. Therefore, the current gunpowder nail gun products are designed with special considerations for the use of safety issues to reduce the probability of accidental hazards.

Furthermore, before the conventional gunpowder nail gun is fired, the nozzle must be held up for a few seconds before the piston part of the nail rod can be slowly moved to the original position of the piston cylinder by the action of gravity. It is ready to be fired), and then a single nail is inserted into the near end of the pipe of the gun mouth, and finally, the trigger is pressed again to make the firing pin impact the gunpowder and produce explosive force, so that the nail bar has an instant impact action (That is, the piston part of the nail rod quickly moves to another position after the shooting of the piston cylinder), and the nail pre-contained at the end of the pipe can be driven into the target; at this time, if the gun nozzle is not up again Stay for a few seconds When the trigger is pressed again, although the trigger can control the firing pin to impact the gunpowder and produce explosive force, the explosive force only fills the piston cylinder, and cannot push the nail rod to move again, resulting in an ineffective firing. As a result, it not only can only fill one nail into the pipe at a time, which makes the operation and use quite inconvenient, but also cannot be used for continuous firing, which reduces its construction efficiency. At the same time, the gun nozzle is facing each time before firing. If the upper stay time is insufficient, the firing force of the nail rod will be reduced, and the nail head of the nail cannot be reliably embedded into the surface of the target, so that the protruding nail head is likely to be accidentally dangerous to others. It happened to be a big trouble.

Therefore, how to develop a more ideal and practical innovative structure in view of the above-mentioned problems of the conventional gunpowder nailer structure is what users expect, and it is also the goal and direction that the relevant industry must strive to develop and break through.

The main content of the gunpowder gun structure of the present invention is to provide a ring groove of the base part of the gun nozzle body by directly buckling the buckle ring so that the ring part can be placed in the retaining sleeve The outer side of the base part, and between the collar part and the elongated hole of the base part, an elastic part, a pressing part and a ball are sequentially accommodated and clamped to form a gun nozzle group, and then the gun nozzle is used One end of the group is accommodated in the limit sleeve seat at one end of the gun body for back and forth movement and rotation, and the end of the nail rod that has been assembled in the gun body can be inserted and slid in the pipe of the gun nozzle group, and The outer surface of the nail rod can be kept in contact with the ball. Therefore, when the nozzle assembly is pressed and moved into the gun body (i.e. retracted), the ball will be simultaneously exposed to the inner wall surface of the pressing part (i.e. inclined surface design). ) And the synchronous clamping and urging action of the outer surface of the nail rod to be linked into a whole shape, so that the nail rod can move with the gun nozzle assembly, and can make The piston part of the nail rod can be accommodated and slid to the starting position in the piston cylinder of the movable piston cylinder seat (that is, the best state of being fired), and can maintain the force system of each firing under continuous firing To maximize, so that the nail head after the impact can be buried below the surface of the target without the accidental danger of scratching others is an advanced proposition.

Another aspect of the present invention is to provide an equidistantly arranged inner concave hole on the circumference side of the base part of the gun nozzle assembly that has been placed in the containment chamber of the limit sleeve seat, and then matched, The adjusting member is screwed into the screw hole of the limiting sleeve, and the end of the adjusting member can be projected to the inside of the receiving chamber of the limiting sleeve, and the end of the adjusting member can surely abut against the gun In this way, it can not only control the rotation angle of the gun nozzle assembly in the limit sleeve seat, but also control the gun case and the gun cartridge that have been assembled at the gun nozzle assembly. The angle between the grips of the gun body, so that it can be applied to construction in different fields, and then greatly enhance its competitiveness is a progressive proposition.

And an elastic member 37 form a gun nozzle group A; in addition, the left depth distance from the inner wall surface of the pressing member 36 that has simultaneously clamped the ball 35 to the elongated hole 302 is lower than the right depth distance [That is, the inclined surface is designed to extend diagonally upward. For example, the inner wall surface of the pressing member 36 is designed with a low left side and a high right side surface design, or the upper hole distance of the elongated hole 302 is greater than the lower hole distance (that is, the elongated hole 302 There is an incompletely penetrating hole or taper hole, etc.)]; In addition, the barrel 31 is provided with at least one fixed groove 310 for positioning the gun case 90, and for sliding the nail 91 already in the gun case 90 Enter the nail inlet 311 inside the pipe 32; in addition, the base portion 30 of the nozzle body 3 is provided with a spring 34 for pushing, so that When the gun nozzle body 3 is not stressed, the bottom end surface of the base portion 30 will be forced to be close to the inner wall surface of the limit sleeve 13, in other words, the adjustment is already located at the screw hole 133 of the limit sleeve 13 One end of the piece 15 can be pressed against the inner concave hole 303, so that the gun case 90 that has been assembled at the gun nozzle body 3 can be effectively positioned, and at the same time, the gun nozzle body 3 and the limiting sleeve can be used There is a rotation function between the seats 13, and the clamping angle between the gun case 90 and the grip portion 110 of the gun body 1 is changed to effectively overcome the problem that the conventional use in the construction site is restricted and cannot be constructed;

The actuating seat 4 is assembled in the accommodating groove 112 of the gun body 11. The actuating seat 4 includes a gunpowder row insertion hole 41, a firing pin accommodating groove 42, and a firing linkage plate 43, wherein the gunpowder The row hole 41 is used for inserting a gunpowder row 410. The gunpowder row hole 41 and the firing pin accommodating groove 42 are arranged in a vertical and staggered relationship with each other. The direction of the firing pin accommodating groove 42 is the same as that of the sleeve member 12 The firing pin accommodating groove 42 has an elongated guiding hole, the firing linkage plate 43 is pivoted at the position corresponding to the elongated guiding hole so as to be swingable, and the firing linkage plate 43 has a receiving hole. The part can be pushed by the pushing part 22 of the trigger unit 2. The firing linkage plate 43 has a firing actuation part facing the elongated guiding hole of the firing pin accommodating groove 42, and the firing linkage plate 43 swings Can be backed up by a torsion spring with elasticity;

A rotatable firing pin 50 is assembled in the firing pin accommodating groove 42 to be capable of axial forward and retreat displacement and radial rotation, and the rotatable firing pin 50 is assembled with a pre-compressed elastic member 51 to make it rotatable The retreat movement of the firing pin 50 can compress the pre-compressed elastic member 51 to accumulate impulse;

A movable protrusion 52 is fixed to the rotatable striker 50 in combination with a The side is in a convex shape, the driven protrusion 52 protrudes out of the elongated guiding hole of the firing pin accommodating groove 42, and the driven protrusion 52 can advance and retreat axially within the range of the elongated guiding hole Displacement and radial swing to link the rotatable striker 50; and when the driven protrusion 52 is at the set axial retreat position, it is exactly opposite to the firing actuation part of the firing linkage plate 43;

A movable piston-cylinder seat 70 is arranged in an axially slidable forward and retreat state inside the casing member 12 at a position near the accommodating groove 112 of the gun body 11. The movable piston-cylinder seat 70 includes a piston cylinder 71 and a gunpowder interface 72 . A front duct 73 and a plurality of exhaust holes 74, wherein the gunpowder interface 72 is opposite to the gunpowder row insertion hole 41 of the actuating seat 4;

A nail rod 80 includes an impact end 81 and a piston portion 82. The impact end 81 is accommodated in the pipe 32 of the gun nozzle body 3 for moving back and forth. The piston portion 82 is slidably accommodated in the Inside the piston cylinder 71 of the movable piston cylinder seat 70;

With the above-mentioned structural composition design, the use and action of the present invention are described as follows:

As shown in Figure 4, it is the 3 pairs of nozzle bodies of the gunpowder nail gun In the empty state, in this state, the movable piston cylinder seat 70 and the push rod 75 are in the preset forward state, and the actuated projection 52 of the rotatable striker 50 and the firing actuation part of the firing linkage plate 43 are out of phase. Therefore, even if we press the button 21 of the trigger unit 2 to cause the firing linkage plate 43 to swing, because the firing actuating part cannot push against the driven projection 52, and the rotatable firing pin 50 has no accumulated impulse. Therefore, the nailing action cannot be generated, so that the uncovered gunpowder nail gun has a safety protection function to prevent accidental air strikes.

Please refer to Figure 5, when the end of the barrel 31 of the nozzle body 3 is pressed against the target 92 and retracted (that is, moved to the right), it will be placed on the base of the nozzle body 3 The collar member 38 on the outer peripheral side of the 30, the pressing member 36 already located in the receiving groove 301 of the base portion 30, the elastic member 37 that has been sandwiched between the inner wall surface of the collar member 38 and the outer wall surface of the pressing member 36 , And the ball 35 that has been sandwiched between the inner wall surface of the pressing part 36 and the elongated hole 302 will move to the right along with the barrel 31, and in addition, it is already located at the base of the barrel 3 A part of the ball 35 in the elongated hole 302 of 30 protrudes into the pipe 32, and the part of the ball 35 that has protruded into the pipe 32 will touch the outer surface of the nail rod 80 and make The other part of the ball 35 will not be pressed by the inner wall surface of the pressing part 36 at all (that is, there is a gap or no contact); therefore, in the moving process, first of all, the base part 30 of the nozzle body 3 The pocket 301 will simultaneously drive the pressing part 36 and the elongated hole 302 to move to the right, and the ball 35 (because the ball 35 is not in contact with the pressing part 36) is only affected by the friction of the nail rod 80 at the beginning The resistance does not follow the pressing part 36 to move to the surface of the pressing part 36 and the nail rod 80 At the same time, the ball 35 is clamped (that is, the ball 35 has moved to the near left side of the pressing member 36) at different positions; furthermore, if it continues to press against the target 92 and retracts (that is, move to the right again) At this time, the pressing member 36, the ball 35 and the nail rod 80 can be moved to the right again until the piston portion 82 of the nail rod 80 is moved to the right side of the piston cylinder 71 (ie At the starting position) to form an optimal ready-to-fire state;

Then, as shown in Figure 6, continue the compressed and retracted state of the gun nozzle body 3 described in the previous paragraph. If we press the button 21 of the trigger unit 2 at this time to cause the firing linkage plate 43 to swing, the firing is The moving part will be able to push against the moved projection 52 to produce an upward radial displacement. Once the moved projection 52 is displaced, the impact elastic force accumulated by the rotatable striker 50 previously due to the compression of the pre-compressed elastic member 51 is instantaneous Released, causing the rotatable firing pin 50 to produce an impact action forward, causing the rotatable firing pin 50 to hit the gunpowder row 410, causing the gunpowder row 410 to be detonated, and its explosive force must be pushed through the gunpowder interface 72 to push the piston that is already located. The piston portion 82 in the cylinder 71 drives the nail rod 80 forward, and uses the striking end 81 to drive the nail 91 already in the pipe 32 into the target 92, thereby achieving the nailing action ；

Please refer to Figure 7. When the construction area is restricted, you only need to press the gun cartridge 90 to move in the direction of the gun body 1 (that is, retract or move to the right, plus, the gun cartridge 90 series Is locked at the gun nozzle body 3), so that the gun case 90 will drive the base portion 30 of the gun nozzle body 3 to move in the accommodation chamber 131 of the limiting sleeve 13, and will cause the base 30 to move in the base The inner recessed hole 303 at the bottom end surface of the seat 30 is completely separated from the end of the adjusting member 15 that has been assembled at the screw hole 133 of the limit sleeve 13; In other words, the adjusting member 15 will not abut against the inner recessed hole 303, so that the base portion 30 of the nozzle body 3 can freely make an arbitrary angle centered on the shaft hole 132 of the limiting sleeve 13 Until any one of the recessed holes 303 on the bottom end of the base portion 30 is aligned with the adjusting member 15, then the inner recessed hole 303 can be pushed toward the sleeve by the reaction of a spring 34 At the end of the adjusting member 15 (that is, the end of the adjusting member 15 abuts against the inner hole 303), in this way, it not only enables the gun case 90 and the gun nozzle body 3 to be in the limit sleeve 13 In addition to the control function of the rotation angle in the chamber 131, it can also change the angle between the gun case 90 and the handle 110 of the gun body 1, so that it is suitable for construction in different fields, thereby greatly improving Its competitiveness.

Please refer to Figure 8, which is a second embodiment of the present invention. The main change is that the limiting sleeve 13 at least includes a threaded portion 130 screwed on one end of the sleeve member 12, and a threaded portion 130 for the A chamber 131 for accommodating the base portion 30 of the nozzle body 3, a shaft hole 132 for accommodating the barrel 31 of the nozzle body 3 and communicating with the chamber 131, and a screw hole for screwing the adjusting member 15 133, and a polygonal trigger part 134 for clamping and applying a tool; as for the above-mentioned gun body 1, the trigger unit 2, the gun nozzle body 3, the spring 34, the ball 35, and the pressing part 36 The elastic member 37, the collar member 38, the buckle 39, the nail rod 80, the gun case 90 and other structures have been described in detail in the above content, so they will not be repeated here.
