Preferably, the shape of the protruding part is a circular truncated cone, and a plurality of first forming grooves are formed in the protruding part. The basic functions of the cap nut are ensured, and meanwhile, the cap nut is convenient to integrally form and produce.

Preferably, the first forming groove is an annular groove, and the first forming groove is circumferentially arranged on the top cover. The processing efficiency of the integrated forming processing of the sealing cap nut is improved.

Preferably, the main part is hexagonal prism in shape, and the surface that the main part is close to the one end of step portion is equipped with a plurality of first chamfers, and the surface that the main part is kept away from the one end of step portion is equipped with a plurality of second chamfers, is equipped with the second shaping groove on the first chamfer. The screwing of the capping nut is facilitated, and meanwhile, the integrated forming processing of the capping nut is facilitated.

Preferably, the first blind hole is a cylindrical hole. The connection of the main body part of the capping nut is facilitated.

Preferably, a second blind hole is formed in the top cover, and the second blind hole is a cylindrical hole. The connection of the cap nut and the cap part is convenient.

Preferably, the aperture of the second blind hole is smaller than that of the first blind hole. The pretightening force of the sealing nut is improved, and the connecting effect of the sealing nut is improved.

Preferably, the first chamfer and the second chamfer are oppositely arranged on the surface of the main body. The surface processing of the capping nut is facilitated.

Preferably, the top cover and the main body are made of stainless steel. The corrosion resistance of the capping nut is improved.

Due to the adoption of the technical scheme, the connecting pipe nut provided by the utility model has the following beneficial effects.

Firstly, the integral forming processing of the capping nut is facilitated, and the production cost of the capping nut is reduced. Secondly, the pretightening force of the sealing cap nut is improved, and the connecting effect of the sealing cap nut is improved. Finally, the capping nut is made of stainless steel, which improves the corrosion resistance of the capping nut.
