Problems solved by technology

[0002] Bolts should not only be easy to use, but also have a certain anti-theft function. Most of the existing anti-theft bolts rely on setting the nuts into a certain shape, and then they must rely on matching tools to open the bolts. In this way, different bolts will be matched. There are different tools, and it is more troublesome to repair and maintain

Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] see figure 1 , the embodiment of the present invention includes:

[0013] An anti-theft U-shaped bolt, comprising: a first nut 1, a first screw rod 2, a second nut 3, a second screw rod 4 and a third nut 5, the first screw rod 2 is arranged in a U shape, and the U shape Both ends have the same height, one end of the U-shape is provided with a through hole, one end of the second screw 4 is provided with a fixed baffle 41, and the second screw 4 passes through the through hole, so The third nut 5 is movably co...

Abstract

The invention discloses an anti-theft U-shaped bolt which comprises a first nut, a first screw, a second nut, a second screw and a third nut. The first screw is in a U shape, and the two ends of the U-shaped first screw are the same in height, and one end of the U-shaped first screw is provided with a through hole. One end of the second screw is provided with a fixed baffle. The second screw penetrates through the through hole. The third nut is movably connected to the second screw. The first nut and the second nut are movably connected to the two ends of the first screw. In this way, a traditional concept that a first nut or a second nut needs to be specially arranged is abandoned, the second screw and the third nut are installed on one end of the first screw, so that the good anti-theft performance is achieved through limiting of the third nut, and the anti-theft U-shaped bolt is wider in using range and better in using effect.

Description

technical field [0001] The invention relates to the field of non-standard hardware, in particular to an anti-theft U-bolt. Background technique [0002] Bolts should not only be easy to use, but also have a certain anti-theft function. Most of the existing anti-theft bolts rely on setting the nuts into a certain shape, and then they must rely on matching tools to open the bolts. In this way, different bolts will be matched. There are different tools, and it is troublesome to repair and maintain. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide an anti-theft U-shaped bolt with better anti-theft performance and wider application range. [0004] In order to solve the above technical problems, the present invention provides an anti-theft U-bolt, comprising: a first nut, a first screw, a second nut, a second screw and a third nut, the first screw is arranged in a U-shape, the Both ends of the U-shape are of the same height,...
