Description
Technical Field
The utility model relates to an automobile bolt technical field, concretely relates to locking car bolt that moves.
Background
The existing automobile assembly process generally needs to use bolts to fasten or position components, but bumping and vibrating can exist in the automobile driving process, and once the bolts are in a vibrating state for a long time, the bolts can loosen and fall off.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, difficult not hard up automobile bolt to the not enough that exists among the above-mentioned background art.
In order to achieve the above object, the utility model relates to a locking car bolt that moves has adopted following technical scheme:
the utility model provides a locking car bolt that moves, includes the bolt body, the bolt body includes bolt head and shank of bolt, the shank of bolt middle part is provided with vertical well kenozooecium, well kenozooecium is worn out the bolt head, be provided with the interior portion in well kenozooecium, interior portion includes upper segment and hypomere, the hypomere includes the elasticity portion to the outside expansion, the upper segment can reciprocate for well kenozooecium.
The utility model relates to a locking car bolt that moves's further improvement part lies in, well kenozooecium upper portion is provided with the internal thread, the upper segment periphery is provided with the external screw thread of internal thread looks adaptation, the upper segment upper end is provided with the end of the gripping of being convenient for.
The utility model relates to a locking car bolt that moves's further improvement part lies in, the center of elasticity portion is vertical cavity form, and the shrink of inside downward sloping, the upper segment is also cavity setting, and upper segment cavity and elasticity portion cavity are provided with the ejector pin.
The utility model relates to a locking car bolt that moves's further improvement part lies in, elasticity portion lower extreme periphery is provided with the non-slip raised.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses well kenozooecium is seted up in the bolt to well kenozooecium setting can outwards support the elasticity portion of pressing, makes the outside conflict of elasticity portion, has strengthened the fixity of bolt, has also reduced certain buffering simultaneously, is applicable to the assembly of car.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 bolt head, 2 bolt rods, 3 upper sections, 4 lower sections, 5 elastic parts, 6 ends and 7 ejector rods.
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 anti-loosening automobile bolt comprises a bolt body, wherein the bolt body comprises a bolt head 1 and a bolt rod 2, a vertical hollow part is arranged in the center of the bolt rod, the hollow part penetrates out of the bolt head, an internal part is arranged in the hollow part, the internal part comprises an upper section 3 and a lower section 4, the upper section and the lower section are fixedly connected, the lower section comprises an elastic part 5 expanding towards the outside, and the upper section can move up and down relative to the hollow part. Furthermore, the center of the elastic part is vertical and hollow, the elastic part is inclined inwards and downwards to contract, the upper section is also hollow, and a push rod 7 is arranged at the hollow part of the upper section and the hollow part of the elastic part. The top rod and the upper section can be inserted and connected or screwed. The periphery of the lower end of the elastic part is provided with an anti-skid bulge (not shown in the figure). The elastic part is enabled to better resist the external anti-skid force, and the stability of the resistance is realized. The hollow part is provided with an internal thread at the upper part, an external thread matched with the internal thread is arranged at the periphery of the upper section, and a head 6 convenient to grasp is arranged at the upper end of the upper section.
The utility model discloses a theory of operation does: with the appointed screw of bolt screw in, rotatory end again drives the upper end and moves down for the elastic component protrusion of hypomere is contradicted with the inside extrusion of screw, pushes down the ejector pin again, makes the conflict of elastic component and screw more inseparable, has realized bolted connection's stability, has prevented not hard up.
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.
