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 connecting piece, in particular a washer, a screw and a screw assembly. The invention provides a washer that is not easy to fall off, comprising a ring-shaped ring body, the upper and lower surfaces of the ring body are respectively a screw contact surface and an object contact surface, and the screw contact surface is provided with annular snap-on protrusions , the inner ring surface of the clamping protrusion is provided with a washer clamping structure. By setting the washer snap-fit ​​structure on the washer and the screw snap-fit ​​structure on the screw, the washer and the screw can be kept fixed in the axial direction, which not only maintains the function of the original washer, but also avoids the washer in the process of removing the screw. fall off to avoid unnecessary loss of gaskets. The snap-fit ​​protrusion of the washer is formed by at least two arc segments, which can improve the elasticity of the snap-fit ​​protrusion and make it easier to snap with the screw.

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...
