Embodiment Construction

[0010] specific implementation

[0011] The interlocking anti-loosening bolt of the present invention will be further described in detail in conjunction with the accompanying drawings to realize the anti-loosening function

[0012] Such as figure 1 As shown, the interlocking anti-loosening bolt assembly of the present invention consists of a slotted nut, a slotted screw, an elastic backstop hook and a common spring washer. The shape of the elastic anti-retraction hook in static state is as follows: image 3 As shown, it is made of ordinary spring material through mechanical processing, and then it is qualitatively formed by heat treatment. The nut is slotted at 120° inside the hexagon of the original shape with an ordinary nut, such as figure 2 shown. The screw uses an ordinary screw to open a vertical slot in the thread part, such as Figure 4 shown. The spring washer is an ordinary spring washer.

[0013] When the nut is pressed tightly, the elastic anti-retraction h...

Abstract

The invention discloses an anti-loosening fastening assembly for bolts. The anti-loosening fastening assembly is composed of a screw with a vertical groove formed in threads, a nut with a vertical groove formed in the corresponding hexagonal inner side, an elastic retaining hook and a common spring washer. Specifically, one part of the elastic retaining hook is inserted into a screw groove and a corresponding nut groove at the same time during working to stop relative movement of the screw and the nut, and the other part of the elastic retaining hook hooks the hexagonal part of the outer sideof the nut to prevent the retaining hook from falling off, so anti-vibration and anti-loosening effects on the whole bolt assembly are achieved. The assembly provided by the invention can be widely applied to connection and fastening places of industrial products, belongs to the technical field of industry, can effectively solve the problem that bolts are easy to loosen in connection and fastening, is easy to disassemble, can be repeatedly used, 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 a bolt assembly for fastening and anti-loosening required by industrial products. Background technique [0003] At present, there are three commonly used fastening methods in industrial products, namely (1) frictional anti-loosening, (2) mechanical anti-loosening, and (3) permanent anti-loosening. Although many methods are included, they all have the disadvantages of poor effect or cumbersome loading and unloading when they are used for a long time and vibrated, and the cost of use is high and wasteful. Contents of the invention [0004] In order to solve the potential safety hazards caused by the bolts being easily loosened by vibration or troublesome loading and unloading in the current technology and reduce maintenance costs during the use of the bolts, the present invention provides a new anti-vibration and anti-loosening bolt that ...
