Description
[technical field]
This utility model is related to the technical field of securing member, the particularly technical field of bolt.
[background technology]
Bolt is a kind of conventional securing member, and it finds broad application in many equipment.General bolt is in vibration feelings
Can loosen under condition, be unfavorable for the safely and effectively operation of equipment.Lock washer etc. sometimes can be coordinated to be used together, but effect
Really not ideal enough, need to improve.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of anti-loosening bolt, can make
It is difficult to loosen after bolt is fixing.
For achieving the above object, the utility model proposes a kind of anti-loosening bolt, including include screw rod, stator,
Turn head, inner bolt, top, push rod, described screw tip is fixed with stator, stator top is fixed with and turns head, fixing
Piece bottom is provided with self-locking burr, and a described center that turns is provided with a groove, and bottom portion of groove is provided with the screwed hole stretching into inside screw,
Screwed hole bottom is provided with cone tank, and taper groove sidewall is provided with some via holes running through screw rod side wall, and auxiliary in the hole is provided with one
Push rod, push rod coats elasticity layer, and push rod one end is located at auxiliary in the hole, and the push rod other end is located in cone tank, and push rod is located at
End face in cone tank is parallel with taper groove sidewall, and described inner bolt is screwed on screwed hole, and inner bolt bottom is fixed with and taper
The top that groove phase is agreed with.
Preferably, the described head that turns is provided with interior hex slot, groove is arranged on the bottom of interior hex slot, and groove is in circle
Shape.
Preferably, described via hole is in horizontal truncated cone, being less than away from cone tank end section of via hole assists
The close cone tank end section in hole.
Preferably, described push rod is in cone away from cone tank end, push rod is agreed with via hole phase.
The beneficial effects of the utility model: this utility model is by being arranged on auxiliary in the hole so that push rod can be by by push rod
Bolt is effectively locked, is difficult to loosen；The setting of self-locking burr makes bolt be difficult to loosen because of vibration, effectively after tightening
Ensure that the fastening effect of bolt；The setting of elastic layer allows inner bolt to unscrew rear push rod to automatically reset, facilitate bolt
Dismounting.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[brief description]
Fig. 1 is a kind of front view of anti-loosening bolt of this utility model.
In figure: 1- screw rod, 2- stator, 3- turn head, 4- groove, 5- inner bolt, 6- push rod, 20- self-locking burr, 30-
Interior hex slot, 40- screwed hole, 41- cone tank, 42- via hole, 51- top, 60- elastic layer.
[specific embodiment]
Refering to Fig. 1, this utility model, including screw rod 1, stator 2, turn a 3, inner bolt 5, top 51, push rod 6, institute
State screw rod 1 top and be fixed with stator 2, stator 2 top is fixed with and turns 3, and stator 2 bottom is provided with self-locking burr 20,
Described 3 center that turn are provided with a groove 4, and groove 4 bottom is provided with the screwed hole 40 stretching within screw rod 1, screwed hole 40 bottom
It is provided with cone tank 41, cone tank 41 side wall is provided with some via holes 42 running through screw rod 1 side wall, is provided with a top in via hole 42
Bar 6, push rod 6 coats elasticity layer 60, and push rod 6 one end is located in via hole 42, and push rod 6 other end is located in cone tank 41,
The end face that push rod 6 is located in cone tank 41 is parallel with cone tank 41 side wall, and described inner bolt 5 is screwed on screwed hole 40, inner bolt 5
Bottom is fixed with the top 51 mutually agreed with cone tank 41, described turn 3 and is provided with interior hex slot 30, in groove 4 is arranged on
The bottom of hex slot 30, groove 4 is rounded, and described via hole 42 is in horizontal truncated cone, via hole 42 away from cone tank
41 end sections are less than close cone tank 41 end section of via hole 42, and described push rod 6 is in cone away from cone tank 41 end, top
Bar 6 is mutually agreed with via hole 42.
Utility model works process:
A kind of anti-loosening bolt of this utility model in the course of the work, turns 3 and tightens bolt, then will be interior
Bolt 5 is screwed down, and is screwed down with inner bolt 5, and push rod 6 moves out, until push rod 6 withstands the external screw thread with bolt cooperation
On, bolt is locked, and bolt is difficult to loosen, and when needing to unload bolt, inner bolt 5 is unscrewed, push rod 6 is anti-elastic layer 60
Elastic force effect is lower to be resetted, and the now no longer locked bolt of push rod 6 is easy to loosen.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
