Fastening bolt and nut assembly beneficial to theft prevention

Abstract

The fastening bolt and nut assembly comprises a screw head and a first T-shaped sliding rod, a transverse rod is slidably connected with a barrel body, a first reset spring is arranged in the barrel body, a bearing is fixedly embedded into the inner top face of the screw head, an inner ring of the bearing is fixedly connected with an internal thread barrel, and the bottom end of the internal thread barrel penetrates into a screw rod and is rotationally connected with the screw rod; a first transverse rod is slidably arranged in the through groove in an attached mode, the section of the first transverse rod is square, T-shaped threaded rods are rotationally arranged in the internal thread barrel, the section of a transverse rod of each T-shaped threaded rod is round, the inclined waist of each trapezoidal block is attached to one end of a transverse rod of a cross-shaped sliding rod, the annular barrel is made of alloy steel materials, and a third T-shaped sliding rod is welded to the corresponding trapezoidal block. And the wall thickness of the cross-shaped sliding rod is 6-10mm, so that the drumstick can repeatedly beat the drum to make a sound to prompt and alarm when the drum is stolen, workers are reminded to inspect, an effective anti-theft effect is achieved, properties are protected, loss is avoided, and the use requirements are met.

Description

technical field [0001] The invention relates to the technical field of anti-theft, in particular to a fastening bolt and nut assembly that is helpful for anti-theft. Background technique [0002] Bolts play a very important role in daily life. In industrial production, bolts occupy a very important position. The types of bolts are simple and the range is too large, so that the anti-theft performance of bolts is very small. However, in some occasions, bolts It is also the first level of anti-theft, so the anti-theft performance of bolts must be paid attention to; the existing anti-theft bolts have certain drawbacks in use. The anti-theft bolts are expensive and have little matching. The anti-theft performance is too low, the function is single, and the practicability is poor. It is easy to be cracked by criminals in a short period of time, and an alarm cannot be generated, resulting in immeasurable losses. It has a certain impact on people's use process and cannot meet the ne...

[0002] Bolts play a very important role in daily life. In industrial production, bolts occupy a very important position. The type of bolts is simple, and the universality is too large, so that the anti-theft performance of bolts is very small. However, in some occasions, bolts It is also the first level of anti-theft, so the anti-theft properties of bolts must be paid attention to; the existing anti-theft bolts have certain disadvantages in use, and the anti-theft bolts are expensive and have little matching. The anti-theft is too low, the function is single, and the practicability is poor. It is easy to be cracked by criminals in a short time, and the alarm cannot be generated, causing immeasurable losses. It has a certain impact on people's use process and cannot meet the use needs.
