Description

Adjustable joint ground resistance tester Technical Field The utility model belongs to the technical field of resistance testers, and particularly relates to an adjustable grounding resistance tester. Background In the safety operation guarantee of facilities such as power system, communication base station, building, etc., the accurate measurement of earth resistance is crucial, and earth resistance tester is as realizing accurate measuring core equipment, and its performance and function directly influence earth system's security aassessment, and at present, the common earth resistance tester in market adopts box formula structure to protect and accomodate the tester main part to satisfy outdoor removal test's demand. The existing grounding resistance tester is characterized in that a tester main body is usually directly placed in a box body, and only a simple supporting leg is arranged at the bottom of the box body. Then resistance tester among the prior art is difficult to deal with the operation demand of co-altitude not when using, in the aspect of connecting wire accomodates, and most current devices only set up simple and easy couple or bandage for twine the connecting wire at will, this kind of mode not only causes the cable to twine easily and tie a knot, in carrying the in-process, loose connecting wire still can rock the collision in the box, not only influences the rational utilization of accommodation space, has more increased the broken risk of cable crust, inside wire. Disclosure of utility model In order to overcome the defects, the utility model provides the adjustable grounding resistance tester, which solves the problems that the resistance tester in the prior art is difficult to cope with the operation demands of different heights when in use, and most of the prior devices are only provided with simple hooks or binding bands for randomly winding connecting wires in the aspect of connecting wire storage. In order to achieve the purpose, the adjustable grounding resistance tester comprises a box body, wherein a supporting block is arranged in the box body in a buckled mode, a tester main body is placed in the supporting block, the bottom of the box body is connected with a support frame in a rotating mode in a symmetrical structure, the support frame is of a U-shaped structure, an extension rod is connected in a sliding mode in the support frame, a threaded rod is connected to the outer side of the support frame in a threaded mode, the threaded rod penetrates through the support frame, the end portion of the threaded rod located in the support frame is in contact with the outer side of the extension rod, a base plate is arranged at the bottom of the extension rod, and a rubber pad is arranged at the bottom of the base plate.
