Problems solved by technology

[0003] With the continuous improvement of the implementation of public infrastructure, many mechanical parts in public areas have become the targets of criminals. The lack of mechanical parts has caused damage to public facilities or can not be used normally. At present, the assembly and disassembly of anti-theft screws can be completed with conventional tools, but it cannot be really done. to the burglar

Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below.

[0015] like Figure 1 to Figure 2 As shown, the present invention discloses a mechanical anti-theft screw, comprising a nut 1 and a threaded rod 2, the nut 1 is fixed at one end of the threaded rod 2, the nut 1 is hemispherical, and the ball center of the nut 1 is located at the end of the threaded rod 2. On the axis, there are three evenly distributed circular holes 3 on the hemispherical surface of the nut 1. If necessary, the positions of the three circular holes can be set at unequal distances. The axis of the circular hole 3 is parallel to the axis of the threaded rod 2.

[0016] In this embodiment, the diameter of the circular hole 3 is 0.6-1.2 mm.

[0017] After many tests and calculations, the depth of the round hole 3 is set to 2mm, that is, after the nut 1 is grooved by the round hole, the minimum distance between the bottom surface and the hemispherical surface is 2mm. This depth is su...

Abstract

The invention discloses a mechanical anti-theft screw. The mechanical anti-theft screw comprises a nut and a threaded rod. The nut is fixed to one end of the threaded rod and is in a semispherical shape. The sphere center of the nut is located on the axis of the threaded rod. Three circular holes which are evenly distributed are formed in the semispherical face of the nut. The axes of the circular holes are parallel to the axis of the threaded rod. The diameter of the circular holes ranges from 0.6 mm to 1.2 mm, and the depth of the circular holes is 2 mm. The mechanical anti-theft screw is simple and ingenious in structure, convenient to disassemble and assemble, safe and reliable.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a mechanical anti-theft screw. Background technique [0002] As a special fastener, anti-theft screws are indispensable and important parts in mechanical assembly. At present, anti-theft screws on the market are hemispherical, cylindrical or conical metal rods with threaded heads and regular depressions, which can be used independently. , such as the Chinese invention patent application number 201020651571.9 discloses an anti-theft screw, the technical solution is to set a cylinder in the inner hexagonal groove, and the cylinder is located in the center of the hexagonal groove. [0003] With the continuous improvement of the implementation of public infrastructure, many mechanical parts in public areas have become the target of criminals. The lack of mechanical parts has caused damage to public facilities or cannot be used normally. At present, the assembly and disassembly of anti-theft ...
