Abstract

The invention discloses an anti-theft bolt with an anti-theft sleeve, which comprises a bolt head, a bolt shaft, an auxiliary cover, an anti-theft sleeve, a slot, and a movable rod. The bolt head is hexagonal, and a bolt shaft is fixed at the center of the bottom of the bolt head. An auxiliary cover with an open lower end is set on the bolt head, and the auxiliary cover and the bolt head are fixed. Cover the through hole of the auxiliary cover, the inner diameter of the through hole is slightly larger than the outer diameter of the auxiliary cover, a ring-shaped slot is provided on the outside of the auxiliary cover, and several side holes corresponding to the slot are provided on the inner wall of the through hole , a movable rod is arranged in the side hole. The invention combines the movable rod with the slot, so that the anti-theft cover and the auxiliary cover are not easy to separate, and they will slip when rotating, so that the bolts are not easy to be twisted, and play a very good anti-theft effect.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, especially the technical field of bolts. 【Background technique】 [0002] Bolt is a kind of fastener commonly used, and its application is comparatively extensive. Bolts are used in fields such as high-speed rail, oil exploration, and wind power, and sometimes some bolts are required to have anti-theft functions. The anti-theft effect of the existing anti-theft bolts is not ideal enough, and cannot meet the demand well, and is easy to be damaged by the opposite direction and lose the anti-theft performance. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose an anti-theft bolt with an anti-theft sleeve, which can make the bolt have good anti-theft performance. [0004] In order to achieve the above object, the present invention proposes an anti-theft bolt with an anti-theft sleeve, including a bolt head, a bolt shaft, ...
