Anti-theft rotating device

Abstract

Disclosed is a theft-proof rotation cover. According to one method, authorization of an electronic cipher is passed, so that opening and closing of a keyhole are controlled electromagnetically; according to the other method, opening and closing of the keyhole are controlled mechanically; one of the two methods is fixedly selected. According to the theft-proof device, the rotation cover can be unplugged until a spring bolt is controlled by a key to be retracted; a fixed bolt or a nut is assembled or disassembled through a tool. The electronic cipher has variability and complexity, so that the disadvantages that theft-proof special shapes of the mechanical nut and bolt are not changeable and high in repetition rate are overcome. A fixed object is sleeved with the rotation cover, and the torque to the fixed object is removed through the technical characteristic that only rotation can be conducted when locking is conducted. The rotation cover can be of any shape in a rotatable space. The rotation cover and a base support of the fixed object bear the impact force to the cover. According to a theft-proof method, a protrusion is clamped in an annular trough in the rotation cover, so that the cover can not move axially, and accordingly the fixed object is prevented from being detached illegally, and release force is cut off through rotation. The theft-proof rotation cover is a defensive obstructing device and applied to the fixed object needing to be protected, such as the bolt or the nut.

Description

technical field [0001] The invention relates to the technical field of preventing illegal disassembly of fixing parts, in particular to an anti-theft rotation device suitable for defensive blocking. Background technique [0002] The anti-theft nuts or anti-theft bolts that are currently used for the fixing parts of the automobile wheel hub all reach the anti-theft means that common general-purpose tools cannot be disassembled with special shapes. However, the anti-theft pattern of the mechanical anti-theft nut or bolt is visible and unchanged. The anti-theft pattern of the fixing part in a car brand has a certain repetition rate. The special loading and unloading tool can remove the anti-theft nuts or bolts of my car tires. In the case of anti-theft, it is still possible to lose the tires. This proves that the mechanical anti-theft nut or bolt has a high repetition rate of special-shaped specifications, and the safety performance is still not high. [0003] For this reason...

AI Technical Summary

Problems solved by technology

[0002] At present, the anti-theft nuts or anti-theft bolts used for the fixing parts of automobile wheels are anti-theft means that cannot be disassembled by ordinary general-purpose tools in special shapes.

However, the anti-theft pattern of the mechanical anti-theft nut or bolt is visible and unchanged. The anti-theft pattern of the fixing part in a car brand has a certain repetition rate. The special loading and unloading tool can remove the anti-theft nuts or bolts of my car tires, and it is still possible to lose the tires in the case of anti-theft

This proves that the mechanical anti-theft nut or bolt has a high repetition rate of special-shaped specifications, and the safety performance is still not high.
