Abstract
The utility model discloses an antitheft thread fastener which comprises a nut (1), and is characterized in that the outer surface of the nut (1) takes the shape of a spherical surface; a groove (2) is formed on the outer surface; and a stress surface (3) vertical to the rotary direction of the nut (1) is arranged in the groove (2). The antitheft thread fastener cannot be detached with common tools such as wrench, pliers and the like, and also cannot be detached by non-regular staff even without dedicated mounting/dismounting tools. Therefore, the antitheft thread fastener has good antitheft effect.
Description
Technical field:
The utility model relates to a kind of fastening piece, and especially a kind of utilization cooperatively interacts is threaded, and can effectively prevent to dismantle, steal the threaded fastener that phenomenon takes place.
Background technique:
Nowadays the threaded fastener that in construction industry, industrial production, generally uses, the cross section of its nut generally is made into regular hexagon, the existing problem of the threaded fastener of this structural type is: with conventional instrument (as spanner, pliers etc.) just can more easily it be disassembled, so just have some lawless persons and steal (theft utilizes steel that threaded fastener links together, aluminium etc.) after with its dismounting, cause great loss to country.
Summary of the invention:
The utility model is in order to solve existing in prior technology the problems referred to above, to provide instruments such as a kind of spanner with routine, pliers can't dismantle the antitheft threaded fastener that anti-theft effect is good.
Technical solution of the present utility model is: a kind of antitheft threaded fastener, comprise nut 1, and it is characterized in that: the outer surface of nut 1 is a sphere, offers groove 2 on it, has one and the orthogonal stress surface 3 of nut 1 sense of rotation in the groove 2 at least.
The utility model is compared with prior art; has following advantage: can prevent effectively that device after the inoperative personnel are to installation or structure from carrying out random dismounting and steal; the device that guarantees that exposure chamber is outer and do not have special messenger's nurse can not be stolen; not only can effectively protect national wealth; can also save great amount of manpower; especially at being placed in open-air various device, adopt antitheft threaded fastener of the present utility model after, anti-theft effect is fairly obvious.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of antitheft threaded fastener, comprise nut 1, nut 1 can be arranged on the bolt end place, also can be the body of nut; The outer surface of nut 1 is a sphere, or the round platform of similar sphere, offers groove 2 on nut 1, is provided with in the groove 2 and the orthogonal stress surface 3 of nut 1 sense of rotation.
During installation, need to use the special installation tool of antitheft threaded fastener, the structure of this instrument is: have a projection that matches with groove 2 shapes, and on this projection with also be the plane on the stress surface 3 contacted positions, projection is arranged on the connecting rod, the end of connecting rod is provided with vertical with it twisting handle, in order to moment of torsion to be provided.
Projection is extend among the groove 2, rotate the twisting handle, bolt or nut body are rotated, thereby reach the purpose of screw threads for fastening.
As not needing dismounting after installing, one of 3 need of stress surface get final product, after installing, need to carry out dismantlement work, just then need at least 2 grooves 2 of setting on the nut 1, and it is opposite to be arranged on the direction of the stress surface 3 on these two grooves 2; During dismounting, only projection need be stretched among the reverse groove 2, counterrotating twisting handle just can realize dismantling operation.
