Abstract

The invention discloses an anti-theft bolt capable of secondary tightening, which comprises a bolt main body, an anti-theft block, a rotating rod, a limit ring, a fixed block, a limit bolt, and an auxiliary hole. The bolt main body is composed of a bolt head and a main screw rod. The main screw rod is fixed on the lower end of the bolt head, and the lower end of the anti-theft block is provided with a cylindrical accommodation groove, the anti-theft block is covered on the bolt head, and the bolt head extends into the accommodation groove, and a A rotatable rotating rod, a limit ring is fixed at the bottom of the rotating rod, a fixed block is arranged on the upper end of the bolt head, and a limit groove is arranged on the fixed block, the limit ring is inserted into the limit groove, and the A limit bolt arranged laterally is screwed on the fixed block. The invention cooperates the rotating rod, the fixed block and the limit bolt so that the anti-theft block can effectively cover the bolt head, and the anti-theft block can rotate under the condition that the bolt head does not move, so that the bolt has better anti-theft performance.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to the technical field of anti-theft bolts. 【Background technique】 [0002] Bolt is a commonly used fastener with a wide range of applications. In some open-air occasions or important joints, bolts are required to have certain anti-theft properties, and anti-theft bolts need to be used. Existing anti-theft bolts are often unable to be tightened twice after installation, which will bring certain troubles to the maintenance of facilities or equipment using anti-theft bolts. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and to propose a second-tighten anti-theft bolt, which can make the anti-theft bolt easy to be tightened and disassembled again under the condition of using a special tool, and is easy to use. [0004] In order to achieve the above object, the present invention proposes a anti-theft bolt that can ...
