[0002] Hexagonal screws or nuts are widely used as fasteners in public facilities, such as electricity, communications, roads, guardrails, bridges, iron towers, etc. Due to the common hexagonal screws or nuts, the hexagonal design is very convenient for installation and disassembly. It can be easily unscrewed with a wrench, and because of this convenience, the anti-theft performance of the hexagonal screws or nuts is poor, which brings great unsafe factors to the above-mentioned facilities and will cause a lot of property damage. Therefore, a kind of anti-theft High performance screws or nuts become required

Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing:
[0018] Such as figure 1 As shown, a kind of easy-to-disassemble anti-theft bolt includes a screw rod and a nut. The top surface of the nut is provided with a cylindrical first groove, and the groove bottom of the cylindrical first groove is provided with The card joint is located in the first groove on the upper part of the card joint, and a cover is installed through threads. The bottom surface of the cover is provided with a second groove for making way for the card joint. The top surface of the cover is provided with a shaft Extending to the third annular groove, the groove wall of the third groove is provided with a locking groove.
[0019] The third groove is used for inserting and disassembling tools.
[0020] The clamping groove is used for clamping the disassembly tool.
[0021] The horizontal section of the clip joint is an irregular polygon.
[0022] The speci...

The invention discloses a thievery prevention bolt easily dismounted and mounted and further discloses a dismounting and mounting tool special for the thievery prevention bolt. The thievery prevention bolt easily dismounted and mounted comprises a screw and a nut, a cylinder-shaped first groove is formed in the top face of the nut, a clamping head is arranged at the groove bottom of the cylinder-shaped first groove, a seal cover is mounted in the position, located on the upper portion of the clamping head, of the first groove through a thread, a second groove used for receding the clamping head is mounted on the bottom face of the seal cover, an annular third groove extending in the axial direction is formed in the top face of the seal cover, and a clamping groove is formed in the groove wall of the third groove. The thievery prevention bolt easily dismounted and mounted and the dismounting and mounting tool special for the thievery prevention bolt have the beneficial effects that the grooves are formed in the top face of the nut of the thievery prevention bolt, the seal cover is arranged in the groove and adopts a structure which can only be dismounted through the special tool, an unconventional dismounting and mounting construction is formed, opening of the seal cover needs the special dismounting and mounting tool matched with the seal cover, the bolt is screwed through a wrench matched with the clamping head accordingly, and thus the thievery prevention property of the thievery prevention bolt is remarkably promoted.
Description
technical field [0001] The invention relates to the technical field of bolt structures, in particular to an easy-to-disassemble anti-theft bolt and a special disassembly tool. Background technique [0002] Hexagonal screws or nuts are widely used as fasteners in public facilities, such as electricity, communications, roads, guardrails, bridges, iron towers, etc. Due to the common hexagonal screws or nuts, the hexagonal design is very convenient for installation and disassembly. It can be easily unscrewed with a wrench, and because of this convenience, the anti-theft performance of the hexagonal screws or nuts is poor, which brings great unsafe factors to the above-mentioned facilities and will cause a lot of property damage. Therefore, a kind of anti-theft High-performance screws or nuts become required. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an easy-to-disassemble anti-theft bol...
