Description

Cap type weld nut

Technical Field

The utility model relates to the technical field of nuts, in particular to the technical field of welded nuts.

Background

The welded nut is made of weldable material, is commonly used on thin-wall sheet metal parts needing to be fastened, is matched with a bolt for use, and is used for enhancing or replacing the connection strength of the thin-wall sheet metal parts. With the rapid development of new energy automobiles, the light weight of the automobiles is particularly important in order to improve the endurance mileage of the automobiles. On the premise of keeping the strength unchanged, the use of thin-walled sheet metal is one of the main ways to achieve light weight. The automobile seat is movably arranged on an automobile frame through a sliding rail, and the sliding rail needs to be fixed with the automobile frame through a welding nut. The existing welded nut has the disadvantages that firstly, a welding point is only designed on the bottom surface of the common nut, and the welded nut with the structure does not have the protection function of corrosion prevention and rust prevention on the bolt; and the other welded nut has the corrosion-resistant and rust-resistant protection function on the bolt, but belongs to a full-sealing structure, and liquid seeped into the nut is difficult to discharge after the electrophoresis treatment of the frame at the later stage, so that the use of the bolt is also influenced.

SUMMERY OF THE UTILITY MODEL

The present invention has been made to solve the above problems, and an object of the present invention is to provide a cap type weld nut which has a corrosion-proof and rust-proof function for protecting a bolt and also can quickly discharge a liquid permeated into the nut.

The technical solution adopted by the present invention to solve the above technical problems is as follows:

the cover-type welding nut is composed of a cylindrical main body, wherein a flange is arranged at the upper part of the main body, a welding bulge is arranged on the upper end face of the flange, a sealing cover is arranged at the lower part of the main body, and a liquid discharge hole is formed in the lower end part of the sealing cover.

Preferably, the welding projection is ring-shaped.

Preferably, the welding projection is point-shaped.

Preferably, the sealing cover and the main body are of an integrated structure.

Preferably, the sealing cover is connected with the main body in a sealing mode.

The utility model adopts the technical proposal to achieve the following beneficial effects:

1. the welding projection is designed on the end face of the flange, so that the welding nut and the sheet metal part can be conveniently and rapidly welded and installed;

2. the welding bulge is made into a ring shape, so that the rapid welding and installation are facilitated, a good sealing effect is achieved, and liquid can be effectively prevented from leaking from the welding position to influence the firmness of the welding position;

3. the sealing cover and the main body are manufactured into an integrated structure, so that the processing is simple;

4. the lower part of the main body is provided with the sealing cover, so that the bolt is protected from corrosion and rust;

5. the lower end face of the sealing cover is provided with the liquid drainage hole, so that liquid in later-stage processing can be drained out of the liquid drainage hole in time after permeating from the thread, the bolt is prevented from being immersed in the liquid, and the bolt is effectively protected from being corroded or rusted.
