Problems solved by technology

However, if the fastened parts are in vibration for a long time, there will be a difference in vibration frequency between the connecting parts, which will cause a certain displacement of each connecting part in the connecting structure, resulting in loosening of the connection between the nut and the bolt, or even falling off. Therefore, the applicant has developed a series of anti-loosening fasteners after long-term research

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention, and should not limit the protection scope of the present invention with this.

[0030] As shown in the figure, this embodiment makes a combination mechanism in which a loosening device, an anti-loosening device and a password device are arranged on the nut 1 . The nut 1 is a polygonal cylinder with a central threaded hole, the central threaded hole is provided with an internal thread 11, and its internal thread 11 constitutes the internal thread ring wall of the nut 1, and it cooperates with the external thread on the stud 2 to complete the alignment. Fastening of fasteners. The loosening, anti-loosening and password combination device includes a card slot 3, a card part 4, a combination disk 5, a chuck chamber 6 and a bayonet pin 7; the card slot 3 is arranged...

Abstract

The invention discloses a password anti-loosening fastener, and belongs to the technical field of fasteners. A loosening, anti-loosening and password combination device is arranged on the fastener. The fastener is a stud or a bolt or a nut or a screw, and a loosening device, an anti-loosening device and a password device are jointly arranged on the stud or the bolt or the nut or the screw. The loosening, anti-loosening and password combination device on the nut comprises a clamping groove, a clamping piece, password discs, a chuck bin and a clamping pin, wherein the clamping groove, password holes in the password discs and the clamping pin jointly form the nut loosening device, the clamping groove and the clamping piece jointly form the anti-loosening device, and the password discs and the chuck bin jointly form the password device. The password anti-loosening fastener has the advantages that the fastener can achieve the anti-loosening effect and the effect that the fastener can be loosened only through a password, and the fastener can be effectively prevented from being unlocked illegally.

Description

technical field [0001] The invention belongs to the technical field of fasteners, in particular to a coded anti-loosening fastener. Background technique [0002] Commonly used fasteners include bolt and nut assemblies, stud nut assemblies, screws, studs, etc., wherein the nut is a polygonal cylinder with a central threaded hole, and an internal thread is provided on the inner ring wall of the central threaded hole. The external thread on the column is tightened, and the stud is a screw rod with a bolt head, and the screw rod is provided with external threads for fastening and connecting two or more fastened parts with through holes. [0003] The fastening of nuts and bolts is generally relatively stable. However, if the fastened parts are in vibration for a long time, there will be a difference in vibration frequency between the connecting parts, which will cause a certain displacement of each connecting part in the connecting structure, resulting in loosening of the connec...
