The utility model discloses set up the elastic cushion block at the nut downside to use miniature bolt to make the elastic cushion block bolt of contradicting, further strengthen the locking between bolt and the nut, guaranteed can not become flexible between bolt and the nut, and then guaranteed that the connection of assembling bolt is firm in the car use.
Description
Technical Field
The utility model relates to an automobile bolt technical field, concretely relates to combination bolt for car.
Background
The use of bolt can not be left in the production assembling process of car, and some bolts need to use with the nut combination, in the use of assembling bolt, receive the influence of automobile vibration for a long time, can have the problem that appears becoming flexible, connect unstably between bolt and nut.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, connect stable automobile assembling bolt to exist not enough among the above-mentioned background art.
In order to achieve the above object, the utility model relates to a combination bolt for car has adopted following technical scheme:
the utility model provides a combination bolt for car, includes the bolt and the nut that cooperate and use, vertical through-hole has been laid to the screw bilateral symmetry of nut, be provided with the internal thread in the through-hole, be provided with the elastic component between nut lower extreme screw and the through-hole, the transverse length of elastic component is greater than the distance between screw and the through-hole, the threaded connection has miniature bolt in the through-hole, miniature bolt and bolt are supported respectively to the elastic component both sides.
The utility model relates to a combination bolt's for car further improves part lies in, the elastic component is spring cushion, spring cushion upper end and nut fixed connection, just spring cushion is big end down.
The utility model relates to a combination bolt's for car further improves part lies in, one side that resilient cushion is close to the bolt is personally submitted arc, be provided with the line on resilient cushion's the convex side, the screw thread on line and the bolt blocks mutually.
The utility model relates to a combination bolt's for car further improves part lies in, the line is including being the horizontal line and the vertical line of laying from top to bottom.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses set up the elastic cushion block at the nut downside to use miniature bolt to make the elastic cushion block bolt of contradicting, further strengthen the locking between bolt and the nut, guaranteed can not become flexible between bolt and the nut, and then guaranteed that the connection of assembling bolt is firm in the car use.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 bolt, 2 nuts, 3 elastic pieces and 4 micro bolts.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the combination bolt for the automobile comprises a bolt 1 and a nut 2 which are matched with each other for use, wherein vertical through holes are symmetrically distributed on two sides of a screw hole of the nut, internal threads are arranged in the through holes, an elastic part 3 is arranged between the screw hole at the lower end of the nut and the through holes, the transverse maximum length of the elastic part is larger than the distance between the screw hole and the through holes, a micro bolt 4 is screwed in the through holes, and two sides of the elastic part respectively abut against the micro bolt and the bolt. Furthermore, the elastic piece is an elastic cushion block, the upper end of the elastic cushion block is fixedly connected with the nut, and the elastic cushion block is in a shape of being small in top and large in bottom. The lower end of the elastic cushion block is large, the bolt can be attached more by the abutting force of the micro bolt, and the stability of connection between the bolt and the nut is further guaranteed. One side of the elastic cushion block, which is close to the bolt, is arc-shaped, and the arc-shaped side of the elastic cushion block is provided with grains which are clamped with threads on the bolt. The lines are contacted with the screw thread in a propping manner, so that the friction force between the elastic cushion block and the bolt when the elastic cushion block is tightly propped against the bolt is increased, and the connection stability is further ensured. Furthermore, the lines comprise transverse lines and vertical lines which are arranged up and down.
The utility model discloses a theory of operation does: the bolt is connected with the nut, the micro bolt is screwed into the through hole after the bolt and the nut are positioned, the micro bolt tightly pushes the elastic cushion block, the elastic cushion block is tightly contacted with the bolt, and the bolt and the nut are further fixed.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
