Description
Technical field
The present invention relates to component of machine, in particular to a kind of bolt.
Background technique
Bolt is machine components, and the connection and fastening or attaching nut for being mainly used for two components use.
Bolt include bolt head and with the integrally formed screw rod of bolt head, the outer surface of screw rod is equipped with external screw thread, is consolidated
Setting tool internal thread threaded hole, when connection, are threadedly engaged by screw rod and threaded hole on fixed component, reach fixed
Purpose, be widely used in people's various fields of recent life, and fixation, but this structure is directed to some movable components, portion
Part can generate vibration, and after a long time, screw rod, which can gradually appear, to be loosened, if it is not anxious when screw rod is tightened into fixation again, connection
Component can fall off, and bring certain influence to people's life, for some automobile components etc., have certain risk, therefore,
Shaking screw rod no matter how all in connection, to will not fall off be the main research direction of the present invention.
Summary of the invention
In order to overcome the shortcomings of background technique, the present invention provides a kind of Anti-off bolts, and no matter how two components shake,
Bolt all will not fall off, and can solve the problem of background technique is proposed.
The technical scheme adopted by the invention is that: a kind of Anti-off bolt includes bolt body, the bolt body packet
Included nut and with the integrally formed screw rod of nut, further include have with screw flight cooperation swivel nut, the bottom of the screw rod
Equipped with a fixed column, the escapement for preventing bolt falling is equipped between the fixed column and swivel nut.
By adopting the above technical scheme, it will will be fixed on connected component by way of welding or being molded first, then spiral shell
Bolt be threadedly coupled, due to screw rod bottom be provided with fixed column, and fixed column and between be provided with escapement, therefore, no matter
How component shakes, and escapement can all promote fixed column and fixation, due to being welded or being moulded on connected component, because
This, screw rod will not fall off, and ensure that the fastness of component, and it is more secured to connect structure of the invention compared to more traditional bolt.
The present invention is further arranged to, and the escapement includes fixation hole, limit hole and limited post, and described consolidates
Determine hole equipped with swivel nut bottom and fixed column can be inserted in fixation hole, the limit hole be equipped with the side wall of fixation hole and with fixation
Hole conducting, the limited post are set to the side of fixed column, and the fixed column, which is equipped with, can promote limited post to be inserted into limit hole
Or skid off the spring mechanism of limit hole.
By adopting the above technical scheme, when the bottom of screw rod rotation, in the fixation hole that fixed column is inserted into, spring mechanism promotees
It is inserted into limited post in limit hole, such limit hole has blocked limited post, no matter how to shake, and limited post all can not be from limit
It is skidded off in hole, it is such simple and practical in structure.
The present invention is further set to: the spring mechanism includes spring and conflict piece, the side of the fixed column
Face, which is equipped with, has the cavity being open, and sliding slot, the both ends point of the conflict piece are respectively equipped at the top of cavity and in the cavity wall of bottom
Be not placed in sliding slot and can slide along the chute, the spring be in cavity, and one end is connect with piece is contradicted, other end conflict and
Be open corresponding cavity wall, and described limited post one end is in cavity to be connect with conflict piece, and the other end can be in by opening
Outside cavity.
By adopting the above technical scheme, due to being provided with spring, for fixed column when inserting to fixation hole, limited post is fixed hole
Cavity wall contradicts, and limited post is exerted oneself towards piece is contradicted, and the both ends for contradicting piece are slided in sliding slot towards spring direction, by spring pressure
Contracting, when fixed column is inserted into bottom, and limited post is directed at limit hole, spring release elastic force promotes conflict piece sliding towards limited post direction
It is dynamic, promote limited post to skid off opening in limit hole, realize limit, in this way after setting, whatsoever in the case of, bolt is not
It can fall off, guarantee the fastness of bolt.
The present invention is further set to: the fixed column is cylindrical body, and the diameter of fixed column is less than the diameter of screw rod
And fixed column and screw rod are integrally formed.
By adopting the above technical scheme, in this way, fixed column and screw rod are integrally formed, it ensure that the jail of fixed column and screw rod
Gu.
Embodiments of the present invention is further illustrated with reference to the accompanying drawing.
Detailed description of the invention

Specific embodiment
Embodiment one:
Refering to attached drawing 1, the present invention provides a kind of Anti-off bolt, includes bolt body 1, and the bolt body 1 includes
Have nut 11 and with the integrally formed screw rod 12 of nut 11, further include having the swivel nut 2 being threadedly engaged with screw rod 12, the screw rod
12 bottom is equipped with a fixed column 3, the escapement 4 for preventing bolt falling is equipped between the fixed column 3 and swivel nut 2, upper
It states in scheme, first will fix swivel nut 2 on connected component by way of welding or being molded, then bolt and 2 spiral shell of swivel nut
Line connection, due to 12 bottom of screw rod be provided with fixed column 3, and fixed column 3 and between be provided with escapement 4, therefore, no matter portion
How part shakes, and escapement 4 can all promote fixed column 3 and fix, due to being welded or being moulded on connected component, because
This, screw rod 12 will not fall off, and ensure that the fastness of component, and it is more firm to connect structure of the invention compared to more traditional bolt
Gu.
In embodiments of the present invention, the escapement 4 includes fixation hole 41, limit hole 42 and limited post 43, institute
The fixation hole 41 stated is equipped with 2 bottom of swivel nut and fixed column 3 can be inserted in fixation hole 41, and the limit hole 42 is equipped with fixation hole
41 side wall is simultaneously connected with fixation hole 41, and the limited post 43 is set to the side of fixed column 3, and the fixed column 3 is equipped with
Limited post 43 can be promoted to be inserted into limit hole 42 or skid off the spring mechanism 5 of limit hole 42, in the above scheme, when screw rod 12 rotates
Bottom when, in the fixation hole 41 that fixed column 3 is inserted into, spring mechanism 5 promotes limited post 43 to be inserted into limit hole 42, in this way
Limit hole 42 has blocked limited post 43, no matter how to shake, and limited post 43 can not all be skidded off out of limit hole 42, such structure letter
It is single practical.
In embodiments of the present invention, the spring mechanism 5 includes spring 51 and contradicts piece 52, the fixed column 3
