Problems solved by technology

[0003] At present, single screws and gaskets are often used to lock the screw holes in the production of industrial products and engineering construction. The commonly used gaskets and screws only produce friction between surfaces during use, and it is difficult to use them for a long time and vibrate. Effectively prevent bolt loosening

Embodiment Construction

[0011] specific implementation

[0012] The realization of the anti-loosening function of the interlocking anti-loosening bolt of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] Such as Figure 4 As shown, the interlocking anti-loosening bolt of the present invention is composed of an elastic washer and a ratchet screw on the head. The elastic washer is in a W-shaped static state, and is made of ordinary spring steel, which is qualitatively formed by heat treatment after stamping and forming. become. When the screw is rotated in the pressing direction, the washer hook C ( figure 2 ) above the height of the plane first hooks the pre-slotted hole of the workpiece to prevent the gasket from rotating, the side ears are tilted from static to vertical, and finally in the working state type, figure 2 The β angle of the middle ear is less than or equal to 90°, which can exert radial friction force on the ratc...

Abstract

The invention discloses an interlocking check bolt assembly, which is composed of a screw and an elastic gasket, wherein the head of the screw is provided with ratchets. Specifically, the interlockingtechnology is achieved by locking the screw and a workpiece via the elastic gasket, and anti-vibration and anti-loosening effects are achieved. The bolt assembly can be widely used in places where industrial products need to be connected and fastened, belongs to the field of industrial technology, can effectively solve the problem that bolts are easy to loosen in connection and fastening of industrial products, and reduces maintenance cost and waste.

Description

[0001] Technical field [0002] The invention relates to the field of fastening and anti-loosening of industrial products, in particular to an elastic gasket and a screw assembly for fastening and anti-loosening of screw holes required by industrial products. Background technique [0003] At present, single screws and gaskets are often used to lock the screw holes in the production of industrial products and engineering construction. The commonly used gaskets and screws only produce friction between surfaces during use, and it is difficult to use them for a long time and vibrate. Effectively prevent bolts from loosening. Contents of the invention [0004] In order to solve the potential safety hazards caused by screws that are easy to loosen under long-term use and vibration working conditions in the prior art, and reduce maintenance costs at the same time, the present invention provides a new anti-vibration and anti-loosening elastic pad that improves the fastening performa...
