Description
Technical field
The utility model relates to a kind of fastening piece more particularly, and it relates to a kind of anti-theft bolt and special tool.
Background technique
Bolt is a kind of common retaining element, and normal conditions are the shaft-like object of taking the lead of attached threaded cylinder.The screwed cylinder part in one end of bolt is called stud, and for coordinating with nut or tapped hole, the other end is head, is called bolt head, for coordinating with spanner.Bolt is generally made of metal, but in special trade, and the bolt that such as uses at the special occasions such as electrical insulation or corrosion protection also has various non-metallic material.
The function of plain bolt and material all comparative maturities, but due to the needs produced and live, occurred the various bolt with specific function in recent years, such as the bolt of warning function, anti-theft feature, but because complex process, theftproof performance are more weak, practicability is not strong.
Model utility content
For the deficiency that prior art exists, it is simple that the purpose of this utility model is to provide a kind of structure, the bolt of good anti-theft effect.
For achieving the above object, the utility model provides following technological scheme:
A kind of anti-theft bolt, comprise bolt body, be provided with circular cavity in described bolt body, described bolt body is provided with the revolving part that to match with circular cavity, described circular cavity madial wall is provided with at least one groove, is provided with the first elastic component between described revolving part and circular cavity.
Preferably, described bolt body top is truncated cone shape or circular arc, and described revolving part top is provided with interior hex slot.
Preferably, described groove is two, is oppositely arranged on chamber inner sidewall.
Compared with prior art, the beneficial effects of the utility model are: be provided with circular cavity in described bolt body, described bolt body is provided with the revolving part that to match with circular cavity, the first elastic component is provided with between described revolving part and circular cavity, when directly turning revolving part, revolving part can not drive bolt body, and the workpiece turning revolving part can block the groove in bolt body, groove is made to be not easy to be found, thus bolt is not directly turned on, reach antitheft function, even and if found the groove on circular cavity inwall, because perforate is less, and position is in madial wall, need not be difficult to open by special instrument, it is simple that the utility model provides a kind of structure, the bolt of good anti-theft effect.
Another object of the present utility model is to provide a kind of special tool for anti-theft bolt in the utility model.
A kind of special tool for anti-theft bolt in the utility model, comprise the collision piece that to match with circular cavity, described collision piece sidewall is provided with baffle plate, described baffle plate is equal to the distance at bolt body top to the Distance geometry groove at collision piece top, described collision piece sidewall is provided with sliding-groove, be provided with expelling means in described sliding-groove, between described expelling means and sliding-groove, be provided with the second elastic component.
Preferably, described expelling means one end is provided with fillet.
The beneficial effects of the utility model are: when collision piece and revolving part are conflicted, with fillet expelling means by circular cavity inwall extruding and indentation sliding-groove in, after collision piece enters circular cavity certain distance, conflict in baffle plate and bolt body top, rotate collision piece again, expelling means ejects and enters in groove, now rotates collision piece again and just bolt can be back-outed, very convenient.

Embodiment
With reference to accompanying drawing, a kind of anti-theft bolt embodiment of the utility model is described in further details.
Referring to figs. 1 through Fig. 4, a kind of anti-theft bolt, comprise bolt body 1, circular cavity 1a is provided with in described bolt body 1, described bolt body 1 is provided with the revolving part 2 that to match with circular cavity 1a, described bolt body 1 top is truncated cone shape or circular arc, ensure that people are difficult to turn bolt by bolt body 1 top, described revolving part 2 top is provided with interior hex slot, interior hex slot has extremely strong fascination, the groove 1b that it is found that in circular cavity 1a can well be stoped, the first elastic component 3 is provided with between described revolving part 2 and circular cavity 1a, when directly turning revolving part 2 by general tool, revolving part 2 can not drive bolt body 1, and the workpiece turning revolving part 2 can block the groove 1b in bolt body 1, groove 1b is made to be not easy to be found, thus bolt is not directly turned on, reach antitheft function, even and if found the groove 1b on circular cavity 1a inwall, because perforate is less, and position is in madial wall, need not be difficult to open by special instrument, and described groove 1b is two, be oppositely arranged on chamber inner sidewall, facilitate opening of special tool 4, it is simple that the utility model provides a kind of structure, the bolt of good anti-theft effect.
With reference to Fig. 5 to Fig. 9, a kind of special tool 4 for anti-theft bolt in the utility model, comprise the collision piece that to match with circular cavity 1a, described collision piece sidewall is provided with baffle plate 7, described baffle plate 7 is equal to the distance at bolt body 1 top to the Distance geometry groove 1b at collision piece top, described collision piece sidewall is provided with sliding-groove, expelling means 5 is provided with in described sliding-groove, the second elastic component 6 is provided with between described expelling means 5 and sliding-groove, and described expelling means 5 one end is provided with fillet, when collision piece and revolving part 2 are conflicted, with fillet expelling means 5 by circular cavity 1a inwall extruding and indentation sliding-groove in, after collision piece enters circular cavity 1a certain distance, conflict in baffle plate 7 and bolt body 1 top, rotate collision piece again, expelling means 5 ejects and enters in groove 1b, now rotate collision piece more just bolt to be back-outed, very convenient.
