Abstract
The utility model discloses a fixing device used for a switching characteristic tester. The fixing device comprises a fixing bolt module, a fixing tester module, and a fixing knob. The fixing tester module is a hollow structure. The fixing bolt module is inserted into the fixing tester module. The fixing knob is threadedly connected with the top surface of the fixing tester module and is arranged at a joint where the fixing bolt module is inserted into the fixing tester module. The bottom of the fixing knob passes through the top surface of the fixing tester module to be abutted against the top surface of the fixing bolt module. The fixing device utilizes a modular design scheme and is suitable for bolts with different diameters. Firm and accurate installation is achieved so as to contribute to increase in testing precision. In addition, the fixing device utilizes splicing structure so as to be convenient for the adjusting and the fixing of the position of the switching characteristic tester.
Description
Technical field
The utility model belongs to the electrical engineering field, relates in particular to a kind of stationary installation for the switching characteristic tester.
Background technology
When the isolating switch in the electric system is carried out performance test, the switching characteristic tester need be fixed on the bolt.
Existing stationary installation as shown in Figure 1, the left side of this stationary installation end face is adsorbed with a location magnet 1, the right side of end face has a screw 2, the weak point of this stationary installation is: one, the aperture of screw 2 is changeless, bolt for different-diameter need be fixed by utilizing pad and nut, has increased workload.Two. the position of 1 pair of switch characteristic tester of use phase magnet is regulated and is fixing, and less stable causes error easily, even causes tester to come off in the reality test.
Summary of the invention
The purpose of this utility model provides a kind of stationary installation that is applicable to multiple diameter bolt and energy stable regulation and the switching characteristic tester of fixing exactly in order to address the above problem.
The purpose of this utility model is achieved in that
A kind of stationary installation for the switching characteristic tester of the present utility model, comprise set bolt module, fixing test instrument module and fixed knob, described fixing test instrument module is hollow structure, described set bolt module is plugged in the described fixing test instrument module, described fixed knob is bolted on the end face of described fixing test instrument module, and be positioned at the grafting side place of described set bolt module and fixing test instrument module, the end face that described fixing test instrument module is passed in the bottom of described fixed knob contacts at the end face of described set bolt module.
Above-mentioned a kind of stationary installation for the switching characteristic tester, wherein, fixedly there is positioning protrusion the center of described fixing test instrument module end face, locates to have a screw on the described set bolt module end face and with respect to the distal side of described fixing test instrument module.
Above-mentioned a kind of stationary installation for the switching characteristic tester, wherein, described screw is different apertures specification.
The utility model employing modularized design scheme, applicable to the bolt of different-diameter, installation more firmly, accurately helps to improve testing precision, simultaneously, adopts splicing construction, is convenient to regulate the also position of floatless switch characteristic tester more.
Description of drawings
Fig. 1 is the structural representation of existing stationary installation;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See also Fig. 2, the stationary installation that the utility model is used for the switching characteristic tester comprises set bolt module 4, fixing test instrument module 3 and fixed knob 5, fixing test instrument module 3 is hollow structure, set bolt module 4 is plugged in the fixing test instrument module 3, fixed knob 5 is bolted on the end face of fixing test instrument module 3, and be positioned at the grafting side place of set bolt module 4 and fixing test instrument module 3, the end face that fixing test instrument module 3 is passed in the bottom of fixed knob 5 contacts at the end face of set bolt module 4.
Fixedly there is positioning protrusion 31 center of fixing test instrument module 3 end faces, locate to have a screw 41 on set bolt module 4 end faces and with respect to the distal side of fixing test instrument module 3, this screw 41 is different apertures specification, for the bolt use of different-diameter size.
During use, actual diameter size according to bolt, select the set bolt module 4 of suitable pore size, and be fixed on the bolt, again set bolt module 4 is inserted in the fixing test instrument modules 3, and regulated the degree of depth of insertion according to the test needs, simultaneously, fixing by positioning knob 5, the switching characteristic tester is fixed on the fixing test instrument module 3 namely finishes installation at last.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
