Bolt beneficial to theft prevention and falling prevention

Abstract

The invention discloses a bolt beneficial to theft prevention and falling prevention. The bolt comprises a polygonal cylinder, teeth mesh with a toothed ring, a vertical rod of a third T-shaped sliding rod sequentially penetrates through a limiting ring and a first circular ring to penetrate into a barrel, the top end of a fifth spring is fixedly connected with the inner top face of an external thread barrel, and the bottom end of the fifth spring is fixedly connected with a transverse rod of the third T-shaped sliding rod. The vertical rod of the third T-shaped sliding rod is fixedly sleeved with a second protruding block, the two ends of the second protruding block are cambered surfaces, the second protruding block is arranged between two second T-shaped sliding rods, the vertical radius of the second protruding block and the vertical sphere diameter of first protruding blocks are located on the same vertical plane, cross-shaped sliding rods are made of alloy steel materials, and the wall thickness of the barrel is 3-5 mm. The toothed ring is connected with first T-shaped sliding rods in a welding mode. The theft prevention or falling prevention purpose can be achieved according to use requirements, the theft time is prolonged, the theft prevention performance is improved, the falling prevention purpose is achieved, normal work of equipment is guaranteed, and the use requirements are met.

Description

technical field [0001] The invention relates to the technical field of bolts, in particular to a bolt that helps prevent theft and fall-off. Background technique [0002] A new type of anti-theft screw. Screws play a very important role in daily life. In industrial production, screws occupy a very important position. The type of screw is simple, and the universality is too large, so that the anti-theft performance of the screw is very small. However, in some occasions, the screw is the first level of anti-theft, so the anti-theft of the screw must be paid attention to; the existing anti-theft screws have certain disadvantages in use, and the anti-theft screws are expensive and have little matching. For the daily use of anti-theft screws Insufficient maintenance, anti-theft screws are too low in anti-theft performance, single in function, and the shape of the screw holes of anti-theft screws is too common, and the uniqueness is not strong enough. Contents of the invention ...
