Anti-falling and anti-theft nut

Abstract

The invention discloses an anti-falling and anti-theft nut. The anti-falling and anti-theft nut is characterized by comprising a nut body, an anti-falling pin and an anti-theft pin; the nut body is of a cylindrical structure, and an anti-disengagement hole communicated with a center hole of the nut body and an anti-theft hole communicated with the anti-disengagement hole are formed in the nut body. The anti-disengaging pin is arranged in the anti-disengaging hole in a sliding mode, and a guide opening is formed in the anti-disengaging pin. The anti-theft pin is arranged in the anti-theft hole in a sliding mode, and a guide head matched with the guide opening is arranged at the inner end of the anti-theft pin. When the outer end of the anti-theft pin is located on the outer side of the anti-theft hole, the nut body can be tightened through the outer end of the anti-theft pin. After the anti-theft pin completely enters the anti-theft hole, the guide head extrudes the guide opening, the end of the anti-falling pin is pressed into the center hole of the nut body, and threads on the screw rod are extruded. The anti-disengaging and anti-theft lock can achieve the anti-disengaging effect and the anti-theft effect.

Description

technical field [0001] The invention relates to the technical field of fasteners, in particular to an anti-loosening anti-theft nut. Background technique [0002] At present, in the connection device that adopts screw nut connection, the nut is easy to loosen or even fall off under the action of severe vibration force, causing the connection piece to fall off. There are pins to prevent the nut from loosening, which prevents hazards caused by the nut falling off. As for the nuts exposed to the outside, because the user is easy to touch, there may be a problem that the user dismounts the nut and disassembles the corresponding locking member, thereby causing the locked structure to be damaged due to misoperation by the user. Secondly, there are also many problems in the market that the locked internal structure is stolen because the fasteners can be easily removed. Therefore, a kind of nut that can prevent falling off and can reach anti-theft effect is urgently needed on the ...
