Abstract

The invention relates to an anti-theft nut structure. The anti-theft nut structure comprises an anti-theft nut structure body, a groove, a soft cushion and a key hole, wherein a threaded strip is mounted on the outer surface of the ant-theft nut structure body; a nut is mounted at the left side of the anti-theft nut structure and is fixedly connected to the anti-theft nut structure; a nut sleeve is mounted in the periphery of the nut and is in threaded connection with the nut; and an outer frame is mounted in the nut sleeve and is in welding connection with the outer frame. The anti-theft nutstructure has the beneficial effects that the threaded strip is arranged at the outer wall of the anti-theft nut structure, and the threaded strip is capable of increasing the frictional force betweenthe nut structure and a dismounting tool while unscrewing or mounting the nut structure, and thus the nut structure can be simply and conveniently dismounted; an irregular hole is formed in the top part of the anti-theft nut structure, thus the nut structure can only be rotatably dismounted through an irregular tool fitting the irregular hole, and as a result, the problem that a theft simply dismounts with a normal tool can be avoided.

Description

technical field [0001] The invention relates to the technical field of nut structures, in particular to an anti-theft nut structure. Background technique [0002] Nuts are one of the most widely used fasteners. Nuts are parts that tightly connect mechanical equipment. Through the inner threads, they are used together with nuts and nut sleeves of the same specification. Loosening or man-made theft damage can cause property and personal safety losses of public facilities up to hundreds of millions of yuan, which has a great impact on the healthy operation of the national economy. Therefore, anti-theft nuts have been widely used and deeply studied. [0003] In the Chinese invention patent CN 201611069703A, an anti-theft nut, the anti-theft nut is cylindrical because the nut outer cover is provided with an ordinary right-handed thread on the outside, which can only be tightened clockwise and cannot be rotated in the opposite direction. This is the first anti-theft method barrie...
