Description

Anti-drop bolt
Technical field
The present invention relates to a kind of bolt, particularly to a kind of anti-drop bolt.
Background technology
Bolt is one of modal securing member, and it is made up of head and screw rod.Screw rod is cylindrical, on external screw thread Can use with nut collocation.Screw bolt and nut is used in conjunction with, and can connect and fix two parts with through hole.Head pressed by bolt Shape can be divided into hexagon-headed bolt, snap bolt, square spigot bolt, dormant bolt etc..
Existing conventional stud in use, due to shake and the impact of stress, easily occur nut loosening or Coming off, coming off of nut causes the disengaging of bolt so that the connection of mechanical part is affected, and easily has an accident.
Summary of the invention
For solving the deficiencies in the prior art, it is an object of the invention to provide a kind of bolt that can effectively prevent bolt from departing from, Realize auto-lock function.
For realizing above-mentioned technical purpose, the technical solution adopted in the present invention is as follows.
Anti-drop bolt includes bolt head, screw rod, and screw rod is made up of thread segment and light bar segment, and the free end of thread segment is fixed Connecting bolt head, the free end of light bar segment is provided with and the inner groovy of screw rod arranged concentric, and the wall portion of light bar segment is provided with interior The chute that groove is connected, in chute, coupling has wedge block, and the flat end face of wedge block is provided with brake pad.
The further improvement of technique scheme, brake pad can use elastic rubber material to make.
It is an advantage of the current invention that: replace nut by self-locking structure, not only reduce cost, and solve nut pine Move or drop, the connection member instability problem caused.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention, the accompanying drawing used required in embodiment will be done simply below Introduce, it should be apparent that, the accompanying drawing in describing below is only some embodiments of the present invention, for ordinary skill people From the point of view of Yuan, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of the present invention.
Figure is denoted as:
100, bolt head；200, screw rod；210, thread segment；220, light bar segment；300, inner groovy；310, wedge block；320, rub Cleaning block；400, upper plate body；500, lower body.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Ground describes, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiment.Based on this Embodiment in bright, those of ordinary skill in the art under not making creative work premise, the every other reality obtained Execute example, broadly fall into scope.
As shown in Figure 1, 2, anti-drop bolt is arranged in upper plate body 400, lower body 500, and anti-drop bolt includes bolt head 100, screw rod 200, screw rod 200 is made up of thread segment 210 and light bar segment 220, and the free end of thread segment 210 fixes connecting bolt head 100, the free end of light bar segment 220 is provided with the inner groovy 300 with screw rod arranged concentric, the wall portion of light bar segment 220 be provided with The chute that inner groovy 300 is connected, in chute, coupling has wedge block 310, the flat end face of wedge block 310 to be provided with friction Block 320；Utilize rod-like members to be inserted in inner groovy, promote stretching out of wedge block 310 so that brake pad 320 and lower body The inwall of 500 contacts, thus reaches self-locking effect.
Preferably, brake pad 320 can use elastic rubber material to make, by the compression of rubber, and both can be by bolt Lock.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention； Multiple amendment to these embodiments will be apparent from, defined in the present invention for those skilled in the art General Principle can realize in other embodiments in the case of without departing from the spirit or scope of the present invention.Therefore, originally Invention will not be defined to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty The widest consistent scope.
