Matching, described polygon body includes the most symmetrical three minor face and three long limits, and the most adjacent two short
Connected by a long limit between limit.
Further, the identical length etc. of each described minor face, the length on each described long limit is the most equal.
Further, each described minor face is outer convex arc edge or straight flange, and each described long limit is straight flange or indent arc
Limit.
Further, described polygon body has an inner ring and thickness from inside to outside in thickness circular mesa-shaped and tapers into
Outer ring.
Further, also including that one can be inserted in described screw rod for playing the lining of liner effect, the endoporus of described lining is big
In the external diameter of described nut, endoporus one end of described lining is provided with a stop edge.
A kind of specific purpose tool for opening above-mentioned anti-theft bolt fastening assembly, including a sleeve, described sleeve one end sets
Square inner bore, the described sleeve other end is had to be provided with the polygon endoporus corresponding with the polygon body shape of described nut.
Further, through by a cylindrical hole between described square inner bore and polygon endoporus.
Compared with prior art, this utility model has the advantage that
In this utility model anti-theft bolt fastening assembly, nut is arranged to be combined into by polygon body and cylinder body
Abnormity nut, only could be opened by special sleeve tool for same described in the utility model, therefore be applied equipment out of doors
In facility, can effectively reduce the theft rate of outdoor equipment facility and parts thereof, improve its theftproof performance.Meanwhile, this is antitheft
Bolt fastening component is simple and reasonable, dismounts the most very convenient.

Detailed description of the invention
This utility model is described in further detail by the embodiment be given below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of anti-theft bolt fastening assembly described in the present embodiment, including screw rod 1 and nut 2, screw rod
1 one end is provided with head 11, and the other end is provided with external screw thread 12, and nut 2 is up-small and down-big step structure, and its upper end is many
Limit body 21, lower end is cylinder body 22.The center of polygon body 21 and cylinder body 22 is provided with through internal thread hole 20, should
Internal thread hole 20 matches with the external screw thread 12 arranged on screw rod 1, and polygon body 21 includes the most symmetrical three
Individual minor face 211 and three long limits 212, connected by a long limit 212 between two the most adjacent minor faces 211.
Preferably, the identical length etc. of each minor face 211, the length on each long limit 212 is the most equal.Outside each minor face 211 is
Convex arc edge or straight flange, each long limit 212 is straight flange or indent arc-shaped side.
Preferably, polygon body 21 has an inner ring in a thickness circular mesa-shaped 213 and thickness from inside to outside and tapers into
Outer ring 214, in this structure, the design of the thickness circular mesa-shaped of inner ring 213 can ensure that the bulk strength of polygon body 21, outer ring
The structure design of 214 then can increase the unlatching difficulty of nut so that only by specific purpose tool side described in the utility model
Can open, non-and then improve its theftproof performance.
Preferably, also including that one can be inserted in screw rod 1 for playing the lining 3 of liner effect, the endoporus 31 of lining 3 is more than nut
The external diameter of 2, so that nut 2 can be inserted in the endoporus 31 of lining 3, endoporus 31 one end of lining 3 is provided with a stop edge 311, should
Stop edge 311 is spacing for described nut 2 is carried out backstop.
As shown in Figure 5 and Figure 6, a kind of special tool for opening above-mentioned anti-theft bolt fastening assembly described in the present embodiment
Tool, including a sleeve 10, sleeve 10 one end is provided with square inner bore 101, and sleeve 10 other end is provided with the polygon body 21 with nut 2
The polygon endoporus 102 that shape is corresponding.When anti-theft bolt fastening assembly described in the utility model opened by needs, only need to be by sleeve
The polygon endoporus 102 of 10 is inserted in the polygon body 21 of nut 2, then screws sleeve 10 and unclamps described nut 2.Meanwhile,
User can also be by inserting a shaft-like spanner at the square inner bore 101 of sleeve 10, thus screwing by this shaft-like spanner
Band moving sleeve 10 unclamps described nut 2, and the unlatching operation that so can make nut 2 is more laborsaving.
Preferably, through by a cylindrical hole 103 between square inner bore 101 and polygon endoporus 102, cylindrical hole
The setting of 103 can save material.
As described above, be only this most novel preferred embodiment, when not limiting the scope of this novel enforcement with this,
The most generally the simple equivalence made according to this novel claim and novel description changes and modifies, and the most still belongs to this new
