Wear-resistant flange nut applied to building support fastener

Abstract

The invention discloses a wear-resistant flange nut applied to a building support fastener. The wear-resistant flange nut comprises a nut body, wherein the nut body is a hexagonal nut, a flange part is arranged at the bottom of the nut body, the cross section of the flange part is round, a locking part is arranged at the top of the nut body, the locking part is a circular truncated cone with a smaller upper part and a larger lower part, a plurality of grooves are uniformly formed in the inclined side wall of the locking part, threaded holes are formed in the nut body, the flange part and the locking part in an up-down penetrating mode, and threads are arranged on the inner wall of the threaded holes. According to the wear-resistant flange nut applied to the building support fastener, the wear resistance property can be improved, the service life of the flange nut can be prolonged, the connection between the flange part and the nut body can be enhanced, the strength of the nut body is improved, the nut body can be opened elastically when the hexagon nut body is screwed, the condition that the pressing force between the locking part and the bolt is too large to cause the permanent deformation of the threads is avoided, the locking force of the hexagonal flange nut can be further improved, and the hexagonal flange nut is not easy to loosen.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of a wear-resistant flange nut applied to building support fasteners. 【Background technique】 [0002] Flange nuts and general hexagon nuts are basically the same size as thread specifications, but compared with hexagon nuts, it is a gasket and nut that are integrated, and there are anti-skid tooth patterns on the bottom, which increases the nut and workpiece. The surface area contact is stronger and stronger than the combination of ordinary nuts and washers. Generally, the specifications of common flange nuts are generally below M20, because most of the flange nuts are used on pipes and flanges, so due to the constraints of the workpiece, the specifications of flange nuts are less than those of nuts. Some flange nuts above M20 are mostly flat flanges, that is, there is no tooth pattern on the flange surface. Most of these nuts are used in some special equ...

Problems solved by technology

[0003] However, the existing flange nuts used in building bracket fasteners have a simple structure and low strength, and the wear between the bracket fasteners and the bracket fasteners is serious during actual operation, which not only affects the aesthetics and the tight connection of the nuts, It also affects the service life
