Description

High-strength anti-skid bolt

Technical Field

The utility model relates to the technical field of bolt and nut fasteners, in particular to a high-strength anti-skidding bolt.

Background

The bolt is a common mechanical part and is widely applied to various industries. When the bolt and nut fastening device is used, a part with a through hole is generally fastened by matching with the nut, but if the bolt and nut are placed in a vibrating environment in the using process, the bolt and nut have the problem of offset sliding, and further the bolt and nut are fastened unstably.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a high-strength anti-skid bolt with simple structure and good anti-skid effect aiming at the defects in the background technology.

In order to achieve the purpose, the utility model discloses a high-strength anti-skid bolt, which adopts the following technical scheme:

the utility model provides a high strength anti-skidding bolt, includes integrated into one piece's bolt head and bolt pole portion, the bolt head is provided with and supports tight structure, support tight structure and include the spacing groove that bolt head periphery side was laid along bolt pole portion length direction, sliding connection has the piece of supporting in the spacing groove, support the piece protrusion in one side that the spacing groove is close to bolt pole portion.

The high-strength anti-skid bolt is further improved in that the two groove walls of the limiting groove are symmetrically provided with downward-inclined limiting plates, the limiting plates are provided with a plurality of groups, the plurality of groups of limiting plates are uniformly distributed in the vertical direction, and the abutting part is provided with an embedding part embedded between the two adjacent groups of limiting plates.

The high-strength antiskid bolt is further improved in that an elastic pad is arranged on the upper side or the lower side of the embedded part.

The utility model further improves the high-strength anti-slip bolt, wherein the lower end of the abutting piece is provided with a tip part, and the upper end of the tip part is screwed on the periphery of the lower end of the abutting piece.

The utility model further provides a further improvement of the high-strength anti-slip bolt, which is characterized in that the periphery of the tip part is in threaded connection with a cylindrical auxiliary interference part.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the abutting part is arranged on the bolt head to abut against and block the screwed part, so that the bolt and the part are prevented from rotating relatively under a vibration working condition, and the stability of bolt connection is further ensured.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure: 1 bolt head, 2 bolt pole portions, 3 spacing grooves, 4 piece, 5 limiting plates, 6 embedding parts, 7 cushion, 8 pointed ends, 9 supplementary conflict parts.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, a high strength anti-skidding bolt, including integrated into one piece's bolt head 1 and bolt pole portion 2, bolt head 1 is provided with and supports tight structure, support tight structure and include the spacing groove 3 that bolt head 1 periphery side was laid along 2 length directions of bolt pole portion, sliding connection has in the spacing groove 3 supports the piece 4, support the piece 4 protrusion in one side that spacing groove 3 is close to bolt pole portion 2. The abutting piece can be a metal piece. Specifically, limiting plates 5 inclined downwards are symmetrically arranged on two groove walls of the limiting groove 3, the limiting plates 5 are provided with multiple groups, the multiple groups of limiting plates 5 are uniformly distributed in the up-down direction, and the abutting piece 4 is provided with an embedding part 6 embedded between the two adjacent groups of limiting plates 5. The limiting plate limits the abutting piece, so that the stability of abutting and blocking of the part is guaranteed, and the anti-skid stability is further realized. Further, an elastic pad 7 is provided on the upper side or the lower side of the insertion portion 6. The stability that the piece self was fixed is kept up. Further, the lower end of the abutting piece 4 is provided with a tip portion 8, and the upper end of the tip portion 8 is screwed on the periphery of the lower end of the abutting piece 4. When the fastened part can be inserted by the tip part, the tip part is inserted, so that the anti-skid effect is better. Further, the periphery of the tip portion 8 is screwed with an auxiliary collision portion 9 in a hollow cylindrical shape. With the cooperation of pointed end portion and then be applicable to different parts, also make simultaneously to support the regulating length of piece, the suitability is stronger.

The working principle of the utility model is as follows: when the bolt fastens the part, the bolt head can contact with the part, adjusts and supports the piece and make to support tight piece protrusion in the spacing groove and in the contact of the part of being fastened, realizes supporting stifled stable effective realization antiskid, can select different contact site according to the part that the difference is fastened and is connected, realizes better antiskid.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model 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.
