Abstract
The invention relates to an anti-falling device for a bolt. The anti-falling device comprises a substrate, a bolt, a fixing frame and a clamping plate, wherein the bolt is connected to the substrate; the fixing frame is fixedly connected with the bolt; the clamping plate is connected with the fixing frame; and the fixing frame and the clamping plate are positioned on both sides of the substrate respectively. According to the device disclosed by the invention, the fixing frame which is fixedly connected with the bolt and the clamping plate which is connected with the fixing frame are arranged on both sides of the substrate, so that the bolt is prevented from falling unexpectedly after a nut falls off.
Description
Technical field
The invention belongs to the link field, be specifically related to a kind of bolt anti-dropping apparatus.
Background technique
In industrial production or daily life, often two objects need to be fixed together, general common employing screw bolt and nut is fixedly connected with two objects, and when needs demounting bolt and nut, or again because the external causes such as vibration exist lower screw bolt and nut often to drop easily, when these two objects are in specific position (such as high altitude environment), dropping of screw bolt and nut can produce potential safety hazard or cause other bad problems.
Nian Zhouming is outstanding to wait the people to apply for a kind of nut anti-dropping device, this device comprises the nut and bolt that the first object and the second object are fixed together, be used for nut is contained in dropping-prevention piece on the first object, described dropping-prevention piece comprise and the interference fit section of the first object interference fit and and the first object Spielpassung between the auxiliary section, crack.Interference fit produces precompression and then produces frictional force and makes dropping-prevention piece firmly fixing when assembling, guarantees that nut does not drop; In when dismounting during bolt, nut produces axial extruding force to dropping-prevention piece, makes dropping-prevention piece interference fit section Direction distortion, has greatly increased the frictional force of dropping-prevention piece, has effectively prevented dropping of nut.
So far, although some innovation and creation about nut anti-dropping device have been arranged, for the technology or the device or few that how to prevent that bolt from dropping.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, a kind of bolt anti-dropping apparatus is provided, this device comprise be positioned at the substrate both sides with the bolt fixing frame that is fixedly connected with and the clamping plate that are connected with fixing frame, guarantee can accident not drop after bolt unclamps.
For solving above technical problem, the technological scheme that the present invention takes is:
A kind of bolt anti-dropping apparatus comprises substrate, is connected to the bolt on the substrate, and the bolt anti-dropping apparatus also comprises the fixing frame that is fixedly connected with bolt, the clamping plate that are connected with fixing frame, and fixing frame and clamping plate lay respectively at the both sides of substrate.
Preferably, be provided with a barb on the fixing frame, offer attachment hole on the clamping plate, described barb passes substrate and penetrates this attachment hole.
Preferably, offer a chute on the substrate, bolt passes this chute movably along the chute length direction, and the width of described chute is less than the size of described fixing frame.
Further preferably, barb passes chute and penetrates in the attachment hole on the clamping plate.
Preferably, the substrate top offers a through hole that supplies fixing frame to pass, and described through hole links to each other with chute.
Preferably, all offer a circular hole that supplies bolt to pass through on fixing frame and the clamping plate.
Because the employing of above technological scheme, the present invention compared with prior art has following advantage:
1, the present invention is by being provided with the fixing frame that is fixedly connected with bolt and the clamping plate that are connected with fixing frame, and fixing frame and clamping plate lay respectively at the both sides of substrate, guaranteed that the nut rear bolt that drops can accident not drop;
When the barb that 2, arranges on the fixing frame of the present invention has effectively prevented mounting nuts, bolts and nuts generation transfer.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is decomposition texture schematic representation of the present invention;
Among the figure: 1, substrate; 2, bolt; 3, fixing frame; 4, clamping plate.
Embodiment
Below in conjunction with drawings and the specific embodiments the present invention is further elaborated.Should be understood that specific embodiment described herein is be used to basic principle of the present invention, major character and advantage are described, and the present invention is not limited by the scope of following examples.
Such as Fig. 1 ~ shown in Figure 2, bolt anti-dropping apparatus provided by the invention, comprise substrate 1, be connected to the bolt 2 on the substrate 1, the bolt anti-dropping apparatus also comprises the fixing frame 3 that is fixedly connected with bolt 2, the clamping plate 4 that are connected with fixing frame 3, and fixing frame 3 and clamping plate 4 lay respectively at the both sides of substrate 1.
Particularly, all offer a circular hole that supplies bolt 2 to pass through on fixing frame 3 and the clamping plate 4, also be provided with a barb on the fixing frame 3, offer attachment hole on the clamping plate 4, offer a chute on the substrate 1, bolt 2 passes this chute 1 movably along the chute length direction, substrate 1 top offers a through hole that supplies fixing frame 3 to pass, described through hole links to each other with chute, and the width of described chute is less than the size of described fixing frame 3, and described barb passes the chute on the substrate 1 and penetrates in the attachment hole on the clamping plate 4.
The working principle of bolt anti-dropping apparatus provided by the invention is as follows:
Such as Fig. 1 ~ shown in Figure 2, during assembling, at first the barb that arranges on the fixing frame 3 is penetrated in the attachment hole on the clamping plate 4, be that fixing frame 3 and clamping plate 4 interconnect, this moment, the cooperation of fixing frame 3 and clamping plate 4 had larger rolling momentum; Then penetrate one piece of bolt 2, bolt 2 passes the circular hole on fixing frame 3 and the clamping plate 4, makes both holes coaxial; Bolt 2 and fixing frame 3 are welded mutually, this moment, fixing frame 3 became one with bolt 2, and with clamping plate 4 larger rolling momentum was arranged, but can not deviate from again; With the through hole of fixing frame 3 and bolt 2 these general alignment substrate 1 tops, slip into substrate 1 along chute, the nut of screwing on from the front at last.
In sum, the present invention is by being provided with the fixing frame that is fixedly connected with bolt and the clamping plate that are connected with fixing frame, and fixing frame and clamping plate lay respectively at the both sides of substrate, guaranteed that the nut rear bolt that drops can accident not drop; Simultaneously, when the barb that arranges on the fixing frame has effectively prevented mounting nuts, bolts and nuts generation transfer.
More than the present invention has been done detailed description; embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof; its purpose is to allow the personage who is familiar with this art can understand content of the present invention and according to this enforcement; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention
