Abstract
The utility model relates to a novel links rod. An insulation rod (1) consists of an inner insulation jacket (3) and an outer insulation jacket (4) which are connected with each other; a special nut (5) is arranged inside the inner cavity of the inner insulation jacket, and the side surface of the special nut is provided with pin hole (6); at the same time, the inner insulation jacket is also provided with a jacket hole (7) corresponding to the pin hole, and a bushing (8) is arranged inside the pin hole and the jacket hole; a spring (9) and a top (10) are arranged inside the bushing. The links rod has the advantages of simple operation, reliability, duration, convenience, safety and light weight, and can be widely applied to the grounding wire, the division/combination falling-typed fuse, and the like.
Description
Technical field: the utility model designs a kind of electrician and uses operation tool, specifically a kind of link rod of novel retractable.
Prior art: understand according to the applicant, power department, factories and miness and rural area electrician generally adopt at present is as appendix Fig. 1, link rod shown in Figure 2.Link rod shown in Figure 1 is threaded by 3 joint insulation rods and forms, because the diameter basically identical of top and low side, so relatively heavier.Sometimes also need to stand on the ladder just can reach when hanging 500kV current transformer primary line, it is just harder to lift this link rod, easily causes operating personnel's fatigue, causes the potential safety hazard in the course of work.Though top end diameter is little shown in the link rod of Fig. 2, weight has lowered, and it is threaded by a kind of of inside, the crucial plastic cement screw thread that is two semi-cylindrical form in the inside of this connection, it is not very reliable connecting, and easily weares and teares, and causes excesssive gap and damages.
Summary of the invention: the technical matters that the utility model solves mainly is to overcome above-mentioned the deficiencies in the prior art, and a kind of novel link rod is provided, though function is the same, it makes its more reliability and durability, convenient, safety by improving the structure of common insulation rod.
Solving the problems of the technologies described above the technical scheme that is adopted is: the utility model comprises insulation rod and operation caput, insulation rod is overlapped to be connected with external insulation sleeve by interior insulation sleeve and forms, it is characterized in that be provided with a special nut at interior insulation sleeve internal cavity, this special nut offers pin-and-hole in the side; Simultaneously also have trepanning, in pin-and-hole and trepanning, be provided with a sleeve pipe in interior insulation sleeve respective pin hole position; In sleeve pipe, be provided with spring and top.The trepanning of being opened in interior insulation sleeve described in the utility model is identical with the pin-and-hole quantity of offering in special nut side, is all 1～6.
The beneficial effects of the utility model are, simple to operate, reliability and durability, convenient, safety, and weight is lighter, but widespread use sockets ground wire, divides, close fuse switch etc.
Below in conjunction with accompanying drawing the utility model link rod is further described:
Description of drawings: Fig. 1 is a kind of prior art link rod;
Fig. 2 is another kind of prior art link rod;
Fig. 3 is special nut structure figure;
Fig. 4 is the inside and outside insulation sleeve linkage section of a utility model cross-sectional view.
Embodiment: the utility model comprises insulation rod 1 and operation caput 2, and insulation rod 1 is overlapped to be connected with external insulation sleeve 4 by interior insulation sleeve 3 and forms, and interior insulation sleeve 3 is withstood by the bottom 11 of external insulation sleeve 4; It is characterized in that be provided with a special nut 5 at interior insulation sleeve 3 internal cavities, this special nut 5 offers pin-and-hole 6 in the side; Simultaneously also have trepanning 7, in pin-and-hole 6 and trepanning 7, be provided with a sleeve pipe 8 in interior insulation sleeve 3 respective pin hole 6 positions; In sleeve pipe 8, be provided with spring 9 and top 10.
The trepanning of being opened in interior insulation sleeve 37 described in the utility model is identical with pin-and-hole 6 quantity of offering in special nut 5 sides, is all 1～6.Present embodiment write off hole 6 quantity are 3, and this 3 hole is uniform on special nut 5, and promptly 120 degree corners are one.On external insulation sleeve 4, also offer an external trepanning 12, corresponding with interior insulation sleeve 3, sleeve pipe 8 can be inserted along the hole.
Claims (2)
1, a kind of novel link rod, comprise insulation rod (1) and operation caput (2), insulation rod (1) is overlapped to be connected with external insulation sleeve (4) by interior insulation sleeve (3) and forms, and it is characterized in that, be provided with a nut (5) at interior insulation sleeve (3) internal cavity, this nut (5) offers pin-and-hole (6) in the side; Also have trepanning (7) in interior insulation sleeve (3) respective pin hole (6) position simultaneously and in pin-and-hole (6) and trepanning (7), be provided with a sleeve pipe (8); In sleeve pipe (8), be provided with spring (9) and top (10).
2, a kind of novel link rod according to claim 1 is characterized in that: the described trepanning of being opened in interior insulation sleeve (3) (7) is identical with pin-and-hole (6) quantity of offering in nut (5) side, is all 1～6.
