Anti -theft bolt has design benefit, rational in infrastructure, succinct advantages such as small and exquisite, convenient to use, easy preparation, low cost, each part cooperation closely, firm in connection, stable good, on anti -theft bolt was used for the iron tower that power line used in power equipment, especially outlying district, the theftproof effect was obvious, had improved the safety and stability nature of line Tower operation, had guaranteed the safe and reliable operation of power transmission sequence.
Description
Technical field
This utility model is related to a kind of bolt, more particularly, to a kind of anti-theft bolt.
Background technology
In actual life, in all trades and professions using extremely widespread, the fixation of many installations and facilities all adopts bolt to bolt
Connect, such as：Equipment, large-sized civil bridge, electric power tower and other special installation of running up etc..Because bolt connection is held
Quick detachable, some facilities and equipments can be removed and steal, its auxiliary oblique material angle of being used of the electric power tower in outlying area
Steel etc. is disassembled to steal and happens occasionally, and leads to the structural stability of steel tower to be affected, or even bar occurs.Fly with economic
Speed development, the safe operation of power network equipment requires more and more higher, and electric power tower is destroyed, and angle steel is stolen, not only state-owned money
Produce loss, more seriously structural unstable steel tower has great potential safety hazard.
Plain bolt is fixed for usual installations and facilities, typically only serves and fastens and anti-loosening effect, using common
Spring shim, does not have anti-theft function, and therefore, the antitheft problem of the steel tower that power circuit uses is it is necessary to find solution.
Utility model content
Technical problem to be solved in the utility model is to overcome the above defect, in conjunction with real work, for existing
A kind of design of situation offer is ingenious, structure is simple, anti-theft bolt that is easy to use, having good anti-theft effect.
In order to solve the problems, such as techniques described above, anti-theft bolt described in the utility model, including nut and screw rod, setting is subject to
Power is tightened up pad and is used cooperatively with described nut；The middle part that described stress tightens up pad is provided with the pad being adapted with described screw rod
Film perforation, the excircle of the described pad hole one side relative with described nut convexes to form tightening ring, and described tightening ring is provided with
Tighten up groove；It is in inclined-plane that the inwall of described nut and described stress tighten up pad close a section, described inclined-plane and nut longitudinal axis shape
Become 30-50 degree tightens up angle a.
Further, groove of tightening up described in the utility model is four, is symmetrical arranged.
Preferably, the angle a that tightens up described in the utility model is 40 degree；The height of tightening ring described in the utility model is 5.
Existing nut is improved by this utility model, and that is, to tighten up pad close for the inwall of described nut and described stress
One section be in inclined-plane, what described inclined-plane and the nut longitudinal axis formed 30-50 degree tightens up angle a；It is adapted with this, design special construction
Stress tightens up pad and described nut mating reaction, and that is, described stress tightens up the excircle of the pad hole of pad and described nut
Relative one side convexes to form tightening ring, described tightening ring is provided with and tightens up groove；During erection bolt, described nut tightens up angle
With stress tighten up pad have tightening ring while relative, the thrust and the stress that produce during described cap rotation tighten up pad phase
Interaction, described tightening ring is staggered with the silk tooth of screw rod embedded, and nut once tightens, and will be unable to exit along silk tooth, as again
Permanently connected, general tool cannot realize disassembled simply, serves antitheft effect.
The beneficial effects of the utility model：Anti-theft bolt described in the utility model and real work are tightly combined, and have and set
Meter is ingenious, rational in infrastructure, succinctly compact, easy to use, easy making, with low cost the advantages of, the cooperation of each part closely, connects
Firmly, good stability；Described anti-theft bolt is used for power equipment, the steel tower that especially backwoodsman power circuit is used
On, anti-theft effect substantially, though little widget, has played big effect, and the safety drastically increasing overhead line structures operation is steady
Qualitative it is ensured that the safe and reliable operation of power transmission sequence.

Specific embodiment
With reference to the accompanying drawings and examples this utility model is described in further detail.
Anti-theft bolt described in the utility model, including nut 1 and screw rod 2, arranges stress and tightens up pad 3 and described nut 1
Use cooperatively；The middle part that described stress tightens up pad 3 is provided with the pad hole 4 being adapted with described screw rod 2, described pad hole 4
The excircle one side relative with described nut 1 convex to form tightening ring 5, described tightening ring 5 is provided with and tightens up groove 6；Described
It is in inclined-plane 7 that the inwall of nut 1 and described stress tighten up pad 3 close a section, and described inclined-plane 7 and the nut longitudinal axis form 30-50
That spends tightens up angle a.
Further, groove 6 of tightening up described in the utility model is four, is symmetrical arranged.
Preferably, the angle a that tightens up described in the utility model is 40 degree；The height of tightening ring 5 described in the utility model is
2.5-3.5㎝.
Embodiment：Stress described in the utility model tightens up that pad 3 is different from conventional pads, and stress tightens up pad 3 middle part
The excircle of pad hole 4 one side relative with described nut 1 convexes to form high 5 tightening ring 5, and symmetrical on tightening ring 5
Car goes out four 1.5 wide gaps, that is, tighten up groove 6, be integrally formed during production；Described nut 1 has special structure, that is, described
It is in inclined-plane 7 that the inwall of nut 1 and described stress tighten up pad 3 close a section, and described inclined-plane 7 and the nut longitudinal axis form 30-50
That spends tightens up angle a.When assembling uses, described nut has to be tightened up angle a and has the while phase of tightening ring 5 when tightening up pad with stress
Right, the thrust and the stress that produce during described cap rotation are tightened up pad and are interacted, the silk tooth of described tightening ring and screw rod 2（Spiral shell
Stricture of vagina）Staggered embedded, nut 1 once tightens, and will be unable to exit along silk tooth again, and as permanently connected, general tool cannot be realized
Disassembled simply, serves antitheft effect.
The special construction of nut described in the utility model, major function position embodies a concentrated reflection of nut inner side chamfering（Tighten up
Angle）The determination of the number of degrees, this utility model has made the nut of six kinds of differing tilt angles, that is,：30 degree, 35 degree, 40 degree, 45 degree,
50 degree, 60 degree, tighten up pad with stress and carry out stressed effect test, result display nut is all unable to disassembled simply and gets off, and 35
Degree, 40 degree, 45 degree ideal, 40 degree of best results of tightening up angle.
