Abstract
The utility model discloses an anti-theft bolt pair used for an electric power iron tower. The anti-theft bolt pair comprises a bolt and a nut, wherein the internal surface of the nut is provided with a fixing groove, and the fixing groove is internally provided with a shrapnel, and the external surface of the bolt is provided with a stopping groove. According to the utility model, the shrapnel is adopted as a one-way stop mechanism, when the nut and the bolt are screwed, the shrapnel is compressed in the fixing groove and does not play a role; and when the nut is disassembled, the shrapnel is popped out and is clamped in the stopping groove, thereby limiting the reverse looseness of the nut, and achieving the anti-theft purpose.
Description
One. technical field: it is secondary that the utility model relates to a kind of bolt, and it is secondary with anti-theft bolt particularly to relate to a kind of electric power tower.
Two. background technique: along with the fast development of electric utility, power circuit is progressively outwards expanded by the city, and the main material that the iron tower of field electric circuit adopts is an angle steel; Adjacent angle steel is by bolt; Because plain bolt does not possess anti-theft feature, its convenient disassembly is so the stolen phenomenon of steel tower corner iron often takes place; Directly influence the safe operation of power supply line, weight person causes power circuit and equipment scrapping.Stolen in order to prevent; The method of general at present employing welding is welded as a whole screw bolt and nut, though this plays certain anti-theft effect, this has also increased the iron tower cost; Increased working strength of workers especially, especially work difficulty is bigger in the massif area.
Three. the model utility content:
The utility model technical problem to be solved is: overcome the deficiency of existing technology, provide a kind of electric power tower simple in structure, easy to use and good anti-theft effect secondary with anti-theft bolt.
The technological scheme of the utility model is: a kind of electric power tower is secondary with anti-theft bolt, contains screw bolt and nut, and the internal surface of said nut is provided with fixed groove, is provided with shell fragment in the said fixed groove, and the outer surface of said bolt is provided with locking groove.
The quantity of said fixed groove is one, and the quantity of said locking groove is more than one, and all said locking grooves are uniformly distributed along the circumference.Another kind of scheme is: the quantity of said fixed groove is more than one, and the quantity of said locking groove is more than one, and the quantity of said fixed groove is identical with the quantity of said locking groove, and all said locking groove and fixed grooves all are uniformly distributed along the circumference.
The beneficial effect of the utility model is:
1, the utility model is provided with the Retchet gear type structure of unidirectional transmission between screw bolt and nut, and nuts and bolt screws when tightening, and shell fragment is inoperative, but when the dismounting nut, the reversing of shell fragment restriction nut is loosening, thereby reaches the antitheft purpose.
2, the utility model adopts shell fragment as unidirectional stop mechanism, simplified structure, and enforcement, and shell fragment good springiness easily, intensity height increase theftproof performance.
3, simple in structure, the easy to use and good anti-theft effect of the utility model has reduced the iron tower fabricating cost, has safeguarded the power circuit safe operation, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is the structural representation of electric power tower with the anti-theft bolt pair.
Five. embodiment:
Embodiment one: referring to Fig. 1, and among the figure, 1-fixed groove, 2-locking groove, 3-nut, 4-bolt, 5-shell fragment.
Electric power tower contains bolt 4 and nut 3 with the anti-theft bolt pair, and wherein: the internal surface of nut 3 is provided with fixed groove 1, is provided with shell fragment 5 in the fixed groove 1, and the outer surface of bolt 4 is provided with locking groove 2.
The quantity of fixed groove 1 is (to be three more than one among the figure; Can certainly be two, four or the like, confirm as required, not detail one by one); The quantity of locking groove 2 is more than one; And the quantity of fixed groove 1 is identical with the quantity of locking groove 2, and all locking grooves 2 all are uniformly distributed along the circumference with fixed groove 1.
Embodiment two: present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: the quantity of fixed groove is one, and the quantity of locking groove is more than one, and all locking grooves are uniformly distributed along the circumference, with simplified structure with reduce cost.
