The invention discloses a sliding type anti-theft bolt. The sliding type anti-theft bolt comprises a bolt head, a bolt rod, an auxiliary cover, a limiting groove, a limiting ring and an auxiliary bolt, wherein the bolt head is cylindrical; the bolt rod is fixedly arranged at the bottom of the bolt head; the auxiliary cover covers the bolt head; the outer part of the auxiliary cover is hexagonal prism; the bottom of the auxiliary cover is provided with an auxiliary groove with a downward opening, and the auxiliary groove is cylindrical; the bolt head extends into the auxiliary groove; the outerside wall of the bolt head is provided with the limiting groove; the bottom of the auxiliary cover is provided with the limiting ring matched with the limiting groove; the limiting ring extends intothe limiting groove; the side wall of the auxiliary groove is provided with a plurality of side holes penetrating through the side wall of the auxiliary groove; and the bolt head is provided with a plurality of side threaded holes. According to the sliding type anti-theft bolt, the bolt head, the auxiliary cover and the auxiliary bolt are matched, the anti-theft bolt can be conveniently screwed down after the auxiliary bolt is screwed on, and the anti-theft bolt is not prone to unscrewing after the auxiliary bolt is screwed out, so that the anti-theft bolt has good anti-theft performance.
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 a slip-type anti-theft bolt, which can make the bolt have good anti-theft performance. [0004] To achieve the above object, the present invention proposes a slipping anti-theft bolt, comprising a bolt head, a bolt shaft, an auxiliary cover, a limiting groove, a li...
