Embodiment Construction

[0013] The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0014] Such as figure 1 Shown is a schematic structural view of the present invention, a special-shaped anti-theft bolt, including a nut, a screw rod 3 and a supporting nut 2, the nut is integrally formed by the nut upper end 5 and the nut lower end 4, the structure of the nut 2 It is a hollow cylinder, and one end surface of the nut 2 is provided with evenly arranged grooves 1, and the uniformly arranged grooves 1 have the same aperture size, and the number is 4-6. The supporting nut 2 of the present invention has changed the previous form and structure, and the nut 2 is designed into a cylindrical shape to prevent thieves from using existing tools such as wrenches to deliver the nut 2, and the nut 2 is provided wi...

Abstract

The invention discloses a special-shaped antitheft bolt. The special-shaped antitheft bolt is characterized by comprising a screw cap, a screw rod and a nut matched with the screw cap and the screw rod in use. The nut is integrally formed by an upper nut end and a lower nut end; the structure of the nut is a hollow cylinder; and grooves evenly arranged are formed in one end of the nut. The special-shaped antitheft bolt has the beneficial effects that the original shape structure is changed for the matched nut, the nut is designed into a cylinder so that a theft can be prevented from loosening and stealing the nut with existing tools such as a wrench, in addition, the grooves are formed in the nut so that a special tool can be used for loosening and locking, and the antitheft effect of the bolt is achieved. According to the special-shaped antitheft bolt, the diameter of the upper nut end is larger than that of the lower nut end so that the upper nut end can effectively shield a pillar body below the upper nut end.

Description

technical field [0001] The invention belongs to an outdoor special-shaped anti-theft device, in particular to a special-shaped anti-theft bolt. Background technique [0002] At present, many public facilities are installed under public conditions. The anti-theft function of the equipment is very poor, and it is easy to be favored by thieves, thus being damaged and stolen. Transformers in remote areas such as rural areas, and batteries installed in base stations are all vulnerable to thieves. Therefore, huge losses of national or business property are caused every year. Judging from the current theft cases, most of the theft of public equipment involves criminals using destructive tools to damage the door locks and then steal the equipment. Therefore, in order to prevent saboteurs from easily destroying the fastening bolts of the stolen equipment. [0003] The matching nuts of common bolts are mostly hexagonal structures. This is done to facilitate tightening with tools suc...
