Description

Bolt structure easy to assemble and disassemble

Technical Field

The utility model relates to the technical field of bolts, in particular to a bolt structure easy to assemble and disassemble.

Background

The bolt is a mechanical part and is a cylindrical threaded fastener matched with a nut. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection. The screw part on the existing bolt is easy to rust, so that the bolt is inconvenient to disassemble.

Therefore, the utility model provides a bolt structure which is easy to assemble and disassemble.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: in order to solve the problems, a bolt structure which is easy to assemble and disassemble is provided.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a bolt structure of easy loading and unloading, includes and twists the head, twist overhead fixedly connected with integrative location portion, round platform part and the screw rod part in proper order, screw rod part goes up to close soon and is connected with the nut and have integrative and the cover establish the cap pipe on screw rod part on the nut, the lower terminal surface of nut has first solid fixed ring and first backing ring, the up end of twisting the head has solid fixed ring of second and second backing ring, the lateral wall of location portion has the ascending tooth of vertical side.

As a further description of the above technical solution:

the positioning part is cylindrical and the outer side wall of the positioning part is uniformly provided with integrated teeth.

As a further description of the above technical solution:

the circular truncated cone part is in the shape of a circular truncated cone.

As a further description of the above technical solution:

first solid fixed ring is integrative with nut and cap pipe, the internally mounted of first solid fixed ring has first backing ring.

As a further description of the above technical solution:

the cap tube is a tubular part with a sealed top end.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. according to the utility model, the screw rod part is covered by the cap pipe, and the first backing ring and the point backing ring are arranged, so that the screwing head and the screw cap have better sealing property when being abutted to a connecting workpiece, rainwater is prevented from entering the screw rod part, the bolt is prevented from rusting, and the bolt is convenient to disassemble.

2. According to the bolt positioning part, the bolt positioning part has better anti-skidding capacity due to the arrangement of the teeth, and the first fixing ring and the second fixing ring are used for protecting the first backing ring and the second backing ring and preventing the backing rings from being damaged due to excessive extrusion.
