Description

Waterproof anti-loosening fastening bolt

Technical Field

The utility model relates to a bolt field particularly, relates to a waterproof locking fastening bolt.

Background

Introduction to

Bolts as fastening components are generally fixed by being aligned by tools and then rotated, and most of the existing bolts are provided with grooves matched with each other for positioning.

In view of the above, the inventor of the present application invented a waterproof and anti-loose fastening bolt.

SUMMERY OF THE UTILITY MODEL

The utility model provides a waterproof locking fastening bolt.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the screw head is provided with at least one annular groove on the side wall, and the annular groove is matched with a sealing rubber ring embedded in the annular groove;

the screw head comprises a columnar first groove for limiting and a second groove for positioning.

Further, the screw head is of a hexagonal structure.

Further, the vertical length of the first groove is greater than the vertical length of the second groove.

Further, the outer part of the screw head is wrapped with a stainless steel cladding layer.

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

(1) carry on spacingly through the first recess of column to pliers body of rod part, and carry on spacingly through carrying on with pliers head assorted second recess, thereby can make the user aim at the screwhead more easily and fix.
