Abstract
The utility model discloses power testing pliers which comprise a plier body. An upper plier nozzle and a lower plier nozzle are arranged on the plier body; binding posts are arranged on the upper plier nozzle and the lower plier nozzle; the plier body is connected with the binding posts by a universal joint; the binding posts are connected with an insulating rod; the insulating rod is formed by a plurality of small sections; and each small section is provided with a male joint and female joint matched with the male joint. In the utility model, the universal joint is arranged between the plier body and the insulating rod; the angle between the plier nozzles and the insulating rod can be regulated by the universal joint, so that the power testing pliers is suitable for testing switching equipment which is installed in a multi-angle mode; moreover, the length of the insulating rod is regulated by adopting a mode that the male joint and the female joint are sequentially connected; and compared with a telescopic insulating rod, the power testing pliers have high reliability.
Description
Technical field
The utility model relates to a kind of power test instrument, is specifically related to a kind of testing clamp.
Background technology
In power industry work, testing clamp is the testing tool of using always, is mainly used in the contact resistance of Test Switchboard equipment.Existing testing clamp is made up of caliper, last lower clamp nozzle, binding post and scalable insulating bar.It mainly exists two scalable insulating bar stability of problem: A. not strong, influence test effect, and B. switchgear setting angle is different, is difficult to test the contact resistance of the switchgear that different angles install.
The utility model content
The technical matters that the utility model will solve is to have the testing equipment that power test pincers stability is bad, be difficult to be directed against different angles now, and a kind of power test pincers of good stability are provided, and can test the contact resistance of the switchgear of different angles installation.
The technical scheme of the utility model realizes in the following manner: a kind of power test pincers; Comprise caliper, caliper is provided with upper clamp nozzle and lower clamp nozzle, and upper clamp nozzle and lower clamp nozzle are provided with binding post; Caliper links to each other with binding post through universal joint; Binding post links to each other with insulating bar, and said insulating bar is made up of some trifles, the female joint that each trifle is provided with male joint and cooperates with male joint.
Be provided with universal joint between caliper and the insulating bar in the utility model; Can regulate the angle between jaw and the insulating bar through universal joint; And then be applicable to the switchgear that the test multi-angle is installed, in addition, adopt male joint and the female joint length of ways of connecting adjusting insulating bar successively; Compare with scalable insulating bar, the reliability of the utility model is high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, a kind of power test pincers comprise caliper 4; Caliper 4 is provided with upper clamp nozzle 5 and lower clamp nozzle 7; Upper clamp nozzle 5 is provided with binding post 6 with lower clamp nozzle 7, and caliper 4 links to each other with binding post 2 through universal joint 3, and binding post 2 links to each other with insulating bar; Said insulating bar is made up of some trifles, the female joint 1 that each trifle is provided with male joint 8 and cooperates with male joint.
When using the utility model, change the length of insulating bar if desired, so just increase or reduce each trifle, adjacent two trifles cooperate through male joint and female joint.
