Description

Anti-slip flange nut Technical Field The utility model relates to the technical field of flange nuts, in particular to an anti-slipping flange nut. Background The flange nut is a nut having a wide flange at one end and can be used as an integral washer. This serves to distribute the pressure of the nut over the secured component, thereby reducing the likelihood of damage to the component. The flange nut plays the function of stably fixing for the part in each field, but in severe environments such as high temperature and high heat environment, the threaded surface only depends on a single plating layer (such as galvanization and nickel plating), the plating layer is easy to damage due to mechanical abrasion, corrosion and clamping are caused, the nut is required to be integrally replaced after corrosion or sealing failure, and the problem of resource waste exists. Disclosure of utility model The utility model aims to solve the problems that in the prior art, in severe environments such as high temperature and high heat environments, the thread surface only depends on a single plating layer (such as zinc plating and nickel plating), the plating layer is easy to damage due to mechanical abrasion, rust and seize are caused, and nuts are required to be replaced integrally after rust or sealing fails, so that resource waste exists. In order to achieve the purpose, the utility model adopts the following technical scheme that the anti-slip flange nut comprises: The square torsion head is provided with a flange plate at the lower end, and the square torsion head and the flange plate are cast into a whole; The lower end of the flange plate is provided with a fluororubber ring, and an annular sealing groove is embedded in the groove; Radial diversion trenches with the trench depth of 1-2mm are arranged at the lower end of the flange plate, the trench bottom inclination angle of the radial diversion trenches is 5-10 degrees, glue injection holes are formed in the side end of the flange plate, and glue injection trenches are arranged between the radial diversion trenches and the side glue injection holes for communication. As a preferable implementation mode, the orifice of the glue injection hole is provided with a plug, the plug is made of stainless steel or nylon, and the plug can be sealed after glue injection to prevent the glue solution from being oxidized and failing from the glue injection hole. As a preferable implementation mode, the surface of the square torsion head internal thread is sequentially provided with an electroplated nickel layer and a PTFE composite coating, and the antioxidation and corrosion resistance of the device are effectively improved through two layers of corrosion resistance. As a preferable implementation mode, anti-skid patterns are arranged on the inner side of the annular sealing groove, and friction force of sealing contact surfaces of the fluororubber rings is enhanced. As a preferred implementation mode, round corner treatment is carried out on the outer side edges of the square torsion heads and the flange plate, the round corner angle is set to be between 1mm and 1.5mm, and through reasonable setting of round corners, the demolding resistance can be obviously reduced, the damage to products and the abrasion to dies are reduced, and the production efficiency is improved.
