The utility model discloses structural design is novel, uses with the cooperation between first spring, the second spring through heart -to -heart talk adjusting collar and round pin crown of roll cover, is connected to do all can between the connecting piece of can insulate pull rod and main shaft one end and adjusts, prolongs the life of insulation pull rod.
Description
Technical field:
This utility model relates to vacuum circuit breaker manufacture field, particularly relates to a kind of vacuum circuit-breaker insulated rod assembly.
Background technology:
Vacuum circuit breaker because of after its arc-extinguishing medium and arc extinguishing the dielectric of contact gap be all fine vacuum and gain the name；It has that volume is little, lightweight, be applicable to frequent operation, advantage that arc extinguishing need not overhaul, applies the most universal in power distribution network.
Damaging the most often occurs in insulated tension pole assembly for vacuum circuit breaker; mainly it is connected by bearing pin between insulated tension pole and the connector of main shaft one end; but this it is connected in actual application often by bigger pulling force or pressure; thus cause the most impaired, need to be replaced.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of vacuum circuit-breaker insulated rod assembly, novel in structural design, can carry out attachment force between the connector of insulated tension pole and main shaft one end and adjust, extend the service life of insulated tension pole.
The technical solution of the utility model is as follows:
Vacuum circuit-breaker insulated rod assembly, including insulated tension pole body, it is characterized in that, described insulated tension pole body is respectively arranged at two ends with vacuum interrupter end connecting hole, main shaft connects end connecting hole, the external wall of insulated tension pole of described vacuum interrupter end connecting hole side is provided with integrated spring catch platform, being additionally provided with thread segment on the outer wall of insulated tension pole body stage casing and screw and be provided with flexible adjustment set, described main shaft connects and is movably installed with bearing pin top cover on the external wall of insulated tension pole of end connecting hole side；
Being respectively installed with the first spring and the second spring on the insulated tension pole body of described flexible adjustment set both sides, the first both ends of the spring is respectively against spring catch platform and flexible adjustment set, and the second both ends of the spring is respectively against flexible adjustment set and bearing pin top cover.
Described vacuum circuit-breaker insulated rod assembly, it is characterised in that described vacuum interrupter end connecting hole, main shaft connect end connecting hole and be respectively circular hole and waist-shaped hole.
Described vacuum circuit-breaker insulated rod assembly, it is characterised in that described bearing pin top cover is cylinder-shaped, bearing pin top cover connects end connecting hole one end towards main shaft and is arranged with bearing pin slot, and bearing pin slot is open slot.
The utility model has the advantages that:
This utility model novel in structural design, by between heart-to-heart talk regulation set and bearing pin top cover and the first spring, the second spring with the use of, attachment force can be carried out between the connector of insulated tension pole and main shaft one end and adjust, extend the service life of insulated tension pole.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
Vacuum circuit-breaker insulated rod assembly, including insulated tension pole body 1, insulated tension pole body 1 is respectively arranged at two ends with vacuum interrupter end connecting hole 2, main shaft connects end connecting hole 3, the external wall of insulated tension pole of vacuum interrupter end connecting hole 2 side is provided with integrated spring catch platform 4, being additionally provided with thread segment screwing on the outer wall of insulated tension pole body 1 stage casing and be provided with flexible adjustment set 5, main shaft connects and is movably installed with bearing pin top cover 6 on the external wall of insulated tension pole of end connecting hole 3 side；
Flexible adjustment is overlapped and is respectively installed with the first spring 7 and the second spring 8 on the insulated tension pole body of 5 both sides, and the first spring 7 two ends overlap 5 respectively against spring catch platform 4 and flexible adjustment, and the second spring 8 two ends are respectively against flexible adjustment set 5 and bearing pin top cover 6.
Vacuum interrupter end connecting hole 2, main shaft connect end connecting hole 3 and are respectively circular hole and waist-shaped hole.
Bearing pin top cover 6 is cylinder-shaped, and bearing pin top cover 6 connects end connecting hole one end towards main shaft and is arranged with bearing pin slot 9, and bearing pin slot 9 is open slot.
In actual use, insulated tension pole body 1 is to tilt to install, and insulated tension pole body 1 vacuum interrupter end connecting hole 2 one end is in lower end, and the bearing pin slot 9 of bearing pin top cover 6 withstands bearing pin under the effect of the first spring 7 and the second spring 8.
