Description

Technical Field

[0001] The utility model relates to the technical field of nuts, and particularly relates to an integrated nut. Background Technique

[0002] A nut is a fastener with internal threads and is used in conjunction with a bolt. The working principle of the nut is to lock itself through the friction between the nut and the bolt. It is mainly convenient for the disassembly and assembly of assembled parts. Depending on its usage and function, there are different designs and classifications, and each type of nut has different specifications. Each type of nut has different mechanical properties and functions. The common washer-integrated nut has poor anti-loosening ability and is prone to nut dropping after a long time.

[0003] The application number is 202122696373.5, and it discloses an integrated nut, belonging to the technical field of nuts. The washer-integrated nut includes a nut body. One side of the nut body is connected with an anti-slip washer, and the outer surface of the nut body is connected with a support block, and the support block is connected with the anti-slip washer. The outer surface of the anti-slip washer is provided with anti-slip convex lines, and a first groove and a second groove are opened on one side of the anti-slip convex lines. The outer surface of the nut body is sleeved with a protective sleeve, and a limiting block is connected to one side of the protective sleeve; through the settings of the anti-slip washer, anti-slip convex lines, first groove and second groove, the utility model increases the friction between the nut body and the bolt, which is beneficial to preventing the nut and the bolt from loosening, and the first groove and the second groove opened on one side of the anti-slip convex lines can increase the heat dissipation area of the anti-slip washer, thereby improving the heat dissipation efficiency of the anti-slip washer.
