Abstract

The invention discloses an anti-theft bolt capable of being screwed up twice. The anti-theft bolt comprises a bolt main body, an anti-theft block, a rotary rod, a limiting ring, a fixed block, a limiting bolt and an auxiliary hole, wherein the bolt main body is composed of a bolt head and a main screw; the main screw is fixedly arranged at the lower end of the bolt head; the lower end of the anti-theft block is equipped with a cylindrical accommodating slot; the anti-theft block covers the bolt head; the bolt head extends into the accommodating slot; a rotatable rotary rod is mounted on the top wall of the accommodating slot; the bottom of the rotary rod is fixedly equipped with a limiting ring; the upper end of the bolt head is equipped with a fixed block; a limiting slot is formed in thefixed block; the limiting ring is inserted into the limiting slot; and a transverse limiting bolt is screwed up on the fixed block. According to the anti-theft bolt disclosed by the invention, the rotary rod, the fixed block and the limiting bolt are matched, so that the anti-theft block can effectively cover the bolt head; and moreover, the anti-theft block can rotate in a case 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 ...
