Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes a washer. The present invention is mainly used to solve the problem that when the existing spring washers are in use, since most spring washers use spring steel materials, when the nuts are tightened too much , it is easy to cause the spring washer to bulge; if a flat washer is added to the spring washer, it is easy to cause the flat washer to be squeezed and dented; if the nut is too small, it will affect the safe operation of the connecting piece

Embodiment Construction

[0021] use Figure 1-Figure 4 A gasket according to one embodiment of the present invention will be described below.

[0022] Such as Figure 1-Figure 4 As shown, a gasket according to the present invention includes a gasket body 1; the gasket body 1 is made of spring steel material, and the gasket body 1 is provided with a cutout 11; the gasket body 1 is provided with a plurality of arc-shaped Recessed groove 12, and the groove depth of one end of a plurality of arc-shaped recessed grooves 12 is greater than the groove depth of the other end; Arc-shaped thin spacer 2 is all installed in a plurality of described arc-shaped recessed grooves, and arc-shaped thin spacer 2 It is set to hard alloy material, and the arc-shaped thin spacer 2 is an interference fit with the arc-shaped concave groove; a limiting groove 13 is set between adjacent arc-shaped concave grooves 12, and a limiting metal block is installed in the limiting groove 13 3, and the limit metal block 3 is set as a ...

Abstract

The invention belongs to the technical field of gaskets, and is specifically a gasket; it includes a gasket body; The groove depth at one end of the arc-shaped concave groove is greater than the groove depth at the other end; arc-shaped thin pads are installed in multiple concave grooves; there are limited slots between adjacent arc-shaped concave grooves, and the installation in the limiting grooves is limited. position metal block, and the limit metal block is set to hard alloy material; the thickness of one end of the arc-shaped thin pad is greater than the thickness of the other end, and multiple arc-shaped thin pads form an annular gasket structure on the washer body; The clamping force of the nut is too large to cause the gasket body to expand; to prevent the flat washer installed on the upper surface of the washer body from sinking downward when the clamping force is too large, which will cause the gasket body to bulge Phenomenon.

Description

technical field [0001] The invention belongs to the technical field of gaskets, in particular to a gasket. Background technique [0002] A type of fastener in the shape of an oblate ring washer. Placed between the supporting surface of the bolt, screw or nut and the surface of the connected part, it plays the role of increasing the contact surface area of ​​the connected part, reducing the pressure per unit area and protecting the surface of the connected part from being damaged; another type of elastic washer, It can also play a role in preventing the nut from coming back loose. [0003] Spring washers and threaded fasteners are used as the mechanical basis for fastening connections, and are widely used in connection parts that are often disassembled. The overall structure of the spring washer is a circular ring with a bevel, which relies on the high elasticity of the spring washer and the sharp edge formed by the edge of the bevel to prevent the fastener from loosening, ...
