Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as Figure 4 and 5 As shown, the gasket of the present invention includes an annular ring body 11, the upper and lower surfaces of the ring body 11 are respectively a screw contact surface and an object contact surface, and the screw contact surface is provided with an annular locking protrusion 12, A washer locking structure 13 is provided on the inner ring surface of the locking protrusion 12 . The clamping protrusion 12 and the ring body 11 are usually integrally formed, the clamping protrusion 12 is coaxial with the ring body 11, and the washer clamping structure 13 on the inner ring surface of the clamping protrusion 12 is used to engage the screw on the screw head 21 The connection structure is matched with the card connection. The clamping structure generally adopts a buckle slot structure, and the slot and the buckle are respectively set on the washer...

Abstract

The invention discloses a connector, and particularly relates to a gasket, a screw and a screw assembly. The gasket not prone to disengagement comprises an annular gasket body, the upper surface and the lower surface of the gasket body are the screw contact surface and the object contact surface respectively, the screw contact surface is provided with an annular clamping protrusion, and the inner ring surface of the clamping protrusion is provided with a gasket clamping structure. Due to the fact that the gasket clamping structure is arranged on the gasket, and a screw clamping structure is arranged on the screw, the gasket and the screw can remain stationary in the axial direction, in this way, the function of an original gasket is kept, gasket disengagement in the screw disassembling process is avoided, and unnecessary loss of the gasket is avoided. The clamping protrusion of the gasket is composed of at least two sections of arc sections, therefore, the elasticity of the clamping protrusion can be improved, and the clamping protrusion can be connected with the screw in a clamped mode more easily.

Description

technical field [0001] The invention relates to connectors, in particular washers, screws and screw assemblies. Background technique [0002] In the connection and installation of mechanical equipment, screws are very important connection parts. Washers are usually used with screws to protect the surface of the connected parts from being scratched by the screw head and disperse the pressure of the screws on the connected parts. The traditional gasket is generally a metal ring, which is sheathed on the screw, and has the advantages of easy processing and low cost. However, in actual use, the gasket is easy to come off from the screw when the equipment is disassembled, which causes the gasket to be scattered and easily lost, which is not conducive to the repeated use of the gasket. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gasket that is not easy to fall off. [0004] The washer adopted by the present in...
