Abstract
The utility model relates to a special theftproof bolt of bolt formula electric power tower, this bolt include nut, screw rod and bolt, and it has three nut recess to open at least on the screw thread of nut, and the nut recess is the rectangular channel, it has a screw rod recess to open on the screw flight, and the screw rod recess is the arc wall. Adopt the utility model discloses, can install the screw rod on the electric power iron tower earlier, screw up the nut again after the test to be harmonious one of them nut recess and screw rod recess, the reinsertion bolt can, because it is perpendicular that the bottom of nut recess and side are, even torsion is huge, the bolt more can block dead screw thread, and all have the recess on nut and the screw rod wherein not taking place the rotation, has more increased the degree of difficulty of destruction screw thread.
Description
Technical field
The utility model relates to a kind of bolt-type power tower Special anti-theft bolt.
Background technique
At present, anti-theft bolt on market is of a great variety, but most of structure is more complicated, as in the patent No. be ZL96210724.7 patent in, its anti-theft screw cap divides inner sleeve and overcoat, and the screw thread of inner sleeve has groove, during use, be tightened on screw rod, to being enclosed within outward and inner sleeve skidded, the groove put in then inserting with iron nail.This anti-theft bolt is not especially suitable for electric power tower etc., because electric power tower is initial in installation, need after running after a while and test, when ensureing incomplete deviation position, nut and screw rod could be completely fixed, and this kind of nut just can not be removed after a procedure.If the overcoat in above-mentioned is removed a kind of anti-theft screw cap of making, only adopt a simple groove and iron nail insert structure, when torsion is enough, is may destroy screw thread on nut completely and loosen nut, just can not reaches antitheft object.
Summary of the invention
It is simple that the purpose of this utility model is to provide structure, and after insertion latch, can guarantee a kind of bolt-type power tower Special anti-theft bolt that nut can not exit from screw rod completely.
The technological scheme that the utility model is taked is: a kind of bolt-type power tower Special anti-theft bolt, comprises nut, screw rod and latch, it is characterized in that on the screw thread of nut, at least have three nut grooves, and the rectangular groove of nut groove; Screw flight has a screw flutes, and the curved groove of screw flutes.
Adopt the utility model, can first screw rod is arranged on electric power tower, tightening nuts again after test, and one of them nut groove and screw flutes are harmonious, then insert latch; Because the bottom of nut groove is vertical with side, even if torsion is huge, latch can not rotate wherein, more can stuck screw thread, and nut and screw rod all have groove, further increases the difficulty destroying screw thread.
Accompanying drawing explanation
Fig. 1 is that of the present utility model cuing open shows schematic diagram.
Fig. 2 is nut schematic side view of the present utility model.
Fig. 3 is screw rod schematic side view of the present utility model.
In figure, sequence number represents: screw rod 1, screw flutes 2, nut groove 3, nut 4 and latch 5.
Embodiment
Below in conjunction with specific embodiment, model utility is described further.
With reference to Fig. 1, Fig. 2 and Fig. 3, this bolt-type power tower Special anti-theft bolt comprises nut 4, screw rod 1 and latch 5, the screw thread of nut 4 at least has three nut groove 3(main purposes be convenient to screw flutes 2 be harmonious with one of them nut groove 3 locate), and the bottom of nut groove 3 and side are vertical, i.e. the rectangular groove of nut groove 3; The screw thread of screw rod 1 has a screw flutes 2, and the bottom of screw flutes 2 is curved, i.e. the curved groove of screw flutes 2.
During use, first screw rod 1 and nut 4 can be arranged on electric power tower simultaneously, but do not insert latch 5 immediately, when electric power tower is through test, if need adjustment, the lower nut 4 of dismounting, tightening nuts 4 to certain position again after reorientating, is harmonious one of them nut groove 3 with screw flutes 2, then exists
Be harmonious position insertion latch 5; Because the bottom of nut groove 3 is vertical with side, even if torsion is huge, latch 5 can not rotate wherein, more can stuck screw thread, and nut 4 and screw rod 1 all have groove, because need to destroy two aspects simultaneously, further increases the difficulty destroying screw thread.In addition, design curved bottom screw flutes 2, object is the space in order to reduce between nut groove 3 and screw flutes 2, makes latch 5 leeway more without spin wherein, and makes latch 5 be convenient to insert.
Claims (1)
