" rural area low-voltage power technical regulation " and " overhead insulating distribution line designing technique code " are pointed out, when the bracing wire of reinforced concrete pole is passed between live wire, it is necessary to guy insulator is installed in bracing wire, and setting height(from bottom) also has corresponding requirements.Guy insulator when meet can bear some tension, in addition it is also necessary to meet there are insulating properties.Guy insulator can be occurred to destroy when the tension force suffered by guy insulator exceedes its maximum tension born (i.e. overtension), seriously can cause down bar and personnel casualty accidents.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of anti-overtension guy insulator being possible to prevent guy insulator overtension and having auto-lock function.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that anti-overtension guy insulator, including insulator, it is respectively arranged at two ends with a bracing wire connecting portion at insulator, described bracing wire connecting portion includes eye bolt and wedge mechanism, the end of eye bolt is provided with screw thread, wedge mechanism is outside is wedge shape holder, wedge shape holder is internal is hollow, it is taper near ring head, it is cylindricality away from ring head, one cross open wedge folder coordinates with wedge shape holder tapered portion position, wedge mechanism is internally provided with steel shim and high-strength spring, ring head screw rod traverse wedge grip, steel shim and high-strength spring, steel shim one side is attached to wedge grip large end face, another side is close to high-strength spring, end near eye bolt is provided with the diameter base less than wedge grip seat pillar shape inflated diameter, base is provided with female thread, can realize sliding in wedge shape holder hollow wall.
Described insulator includes composite cluster parachute, and metal crimp is overlapped and plug, and metal crimp set crimps with plug；Metal crimp set front end is provided with boss, and boss contacts with base, is provided with screw thread outside pressure welding case.
Described wedge grip seats against nearly insulator end and is provided with female thread, in mating connection with the outside screw thread arranged of pressure welding case.
The female thread of described base is in mating connection with the end external screw thread of eye bolt.
Described wedge grip need to exceed wedge shape holder taper large end face certain distance.
This utility model has the advantages that:
When hightension was born in bracing wire, eye bolt is pulled to drive base to slide in wedge shape holder, base compression spring makes guy insulator extend, reduce the overtension effect to guy insulator, prevent guy insulator from destroying under overtension effect, compressing spring simultaneously at base, spring effect steel shim and wedge grip, wedge grip shrinks also clamping ring head screw rod under spring pressure effect and realizes self-locking.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As Figure 1-4, anti-overtension guy insulator, including insulator 3, it is respectively arranged at two ends with a bracing wire connecting portion at insulator 3, described bracing wire connecting portion includes eye bolt 1 and wedge mechanism, the end of eye bolt 1 is provided with screw thread 11, wedge mechanism is outside is wedge shape holder 2, wedge shape holder 2 is internal is hollow, it is taper near ring head, it is cylindricality away from ring head, one cross open wedge folder 5 coordinates with wedge shape holder 2 taper position, wedge mechanism is internally provided with steel shim 6 and high-strength spring 7, ring head screw rod 12 traverse wedge grip 5, steel shim 6 and high-strength spring 7, steel shim 6 one side is attached to wedge grip 5 large end face, another side is close to high-strength spring 7, end near eye bolt 1 is provided with the diameter base 8 less than wedge shape holder 2 cylindricality inflated diameter, base 8 is provided with female thread 81, can realize sliding in wedge shape holder 2 hollow wall.
Further, insulator 3 includes composite cluster parachute 4, and metal crimp overlaps 31 and plug 33, and metal crimp set 31 crimps with plug 33；Metal crimp set front end is provided with boss 34, and boss 34 contacts with base 8, is provided with screw thread 32 outside pressure welding case.
Further, wedge shape holder 2 is provided with female thread 21 near insulator 3 end, in mating connection with the outside screw thread 32 arranged of pressure welding case.
Further, the female thread 81 of base 8 is in mating connection with the end external screw thread 11 of eye bolt 1.
Further, wedge grip 5 need to exceed wedge shape holder 2 taper large end face certain distance 9.
Concrete, concrete being embodied as of this example: first wedge grip 5 is put near insulator 3 end wedge shape holder 2, coordinate with wedge shape holder 2 taper position, it is sequentially placed into steel shim 6 and spring 7 again, ring screw 12 is penetrated successively wedge grip 5, steel shim 6 and spring 7, screw rod 12 adopts threaded engagement to be connected with base 8 and tightens, mounted wedge shape holder 2 is coordinated with being threaded connection of insulator 3, in rundown process, pressure welding case boss heads on base 8 slide downward and compresses spring 7, according to above-mentioned, whole guy insulator is completed.
