Two objects of human use's bolt link, or a certain component is tightly held in the surface of another object using bolt,
The range of application of bolt is extremely wide, and the early stage bolt of production loosens poor performance, and under vibrational state, bolt easily loosens, early
The bolt of phase, dismounting is extremely difficult, there is maintenance of equipment and the difficult defect of member replacing.
Utility model content
The purpose of this utility model is to provide a kind of self-tightening type check bolt, good excellent with quick detachable with performance is loosened
Point, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of self-tightening type check bolt, including bolt
Body, the body of bolt is made up of self-locking bolt, tightening nut, latch, self-tightening spring, nut and clamping thing, the self-locking bolt
It is provided with tightening nut, self-locking bolt runs through tightening nut, is provided with latch on tightening nut, one end of latch is through tightening spiral shell
Mother, and the inside of self-locking bolt is extended to, the other end of latch extends tightening nut, and self-tightening is provided with the bottom of tightening nut
Spring, one end of self-tightening spring is connected with tightening nut, and the other end of self-tightening spring is connected with clamping thing, at the top of clamping thing
It is provided with nut.
As further program of the utility model：The self-tightening spring is the big small structure of two ends external diameter of intermediate outer.
As further program of the utility model：The center of the tightening nut and nut is on the same line.
Compared with prior art, the utility model beneficial effect：
Latch, using self-tightening spring assembly, is fixedly installed on tightening nut by the utility model self-tightening type check bolt
Inside, plays a part of powerful fixation, and the self-tightening type check bolt is applied to the component connection under vibrational state, and vibration equipment is produced
Raw gap is compensated by self-tightening torque, and clamping torque can be maintained not diminish, and under vibrational state, will not also be loosened
Phenomenon, and can be dismantled between each part of self-locking bolt, can reinstall, be easy to equipment maintenance and accessory more
Change.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
In figure：The 1- bodies of bolt；11- self-locking bolts；12- tightening nuts；13- latches；14- self-tightening springs；15- nuts；16-
Clamping thing.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of self-tightening type check bolt, including the body of bolt 1, the body of bolt 1 by
Self-locking bolt 11, tightening nut 12, latch 13, self-tightening spring 14, nut 15 and clamping thing 16 are constituted, and self-locking bolt 11 is provided with
Tightening nut 12, tightening nut 12 is used to fix self-locking bolt 11, plays fixed effect, and self-locking bolt 11 runs through tightening nut
12, latch 13 is provided with tightening nut 12, tightening nut 12 is run through in one end of latch 13, and extends to the interior of self-locking bolt 11
Portion, the other end of latch 13 extends tightening nut 12, and latch 13 plays a part of powerful fixation, prevents bolt looseness, is turning round
The bottom of tight nut 12 is provided with self-tightening spring 14, and self-tightening spring 14 can play buffering well in the case of vibrational state
Effect, prevents bolt looseness, and the inner side of self-tightening spring 14 is self-locking bolt 11, under vibrational state, between vibration equipment is produced
Gap is compensated by self-tightening torque, and clamping torque can be maintained not diminish, and under vibrational state, what will not also be loosened shows
As, prevent one end of bolt looseness, self-tightening spring 14 to be connected with tightening nut 12 well, the other end of self-tightening spring 14 with
Clamping thing 16 is connected, and nut 15 is provided with the top of clamping thing 16, tightening nut 12 and nut 15 in the same horizontal line, self-tightening
Can be dismantled between each part of bolt 11, can reinstalled, be easy to maintenance of equipment and member replacing.
