Description
Technical field
The utility model relates to powder technology field, more specifically relates to a kind of voltage tester line spool of free-extension.
Background technology
When utilizing portable electric energy quality monitoring instrument to test, need its voltage tester line to be connected on the different secondary circuit terminal row of height, existing voltage tester line is regular length type, its length can not change, as needed extended testing system line, different testing wire need be coupled together, thus reduce reliability and the accuracy of test signal transmission.As made the longer testing wire of length, the work capacity of coiling during use can be increased, reducing work efficiency.
Summary of the invention
(1) technical matters that will solve
The technical problems to be solved in the utility model is exactly the problem in order to solve changed test line length short strip is come when different measuring distance reliability and accuracy, and increases the problem of coiling work capacity, and provides a kind of voltage tester line spool of free-extension.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of voltage tester line spool of free-extension, and this line spool comprises spool 1, left end cap 2, right end cap 3, coil spring 4, cylindrical tube 5, wire 6, line outlet 7 and 8, card line tongue 9.
Wherein, left end cap 2 and right end cap 3 are separately positioned on cylindrical tube 5 both sides, at cylindrical tube 5, central authorities are provided with spool 1, the left end of spool 1 is movably arranged in the centre hole of left end cap 2, the right-hand member of spool 1 is movably arranged in the centre hole of right end cap 2, coil spring 4 is fixedly connected with the central outer arm of spool 1, coil spring 4 is provided with card line tongue 9 with the junction of spool 1, the external side end of coil spring 4 is fixedly connected with the medial surface of cylindrical tube 5, the central authorities of wire 6 are articulated on card line tongue 9, and left end cap 2 and right end cap 3 are provided with line outlet 7 and 8.
(3) beneficial effect
The utility model be portable electric energy quality monitoring instrument provide connect height different, arrange apart from different secondary terminals time retractable testing wire, avoid the different testing wire connection work carried out for extended testing system line, decrease the work capacity of coiling, improve reliability and the accuracy of test, improve work efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the voltage tester line spool of the utility model free-extension;
Mark in figure: 1 spool, 2 left end caps, 3 right end caps, 4 coil springs, 5 cylindrical tubes, 6 wires, 7 and 8 line outlets, 9 card line tongues.
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
The utility model provides a kind of voltage tester line spool of retractable, as shown in drawings, comprise cylindrical tube 5 and wire 6, left end cap 2 and right end cap 3 is respectively arranged with in cylindrical tube 5 both sides, at cylindrical tube 5, central authorities are provided with spool 1, the left end of spool 1 is movably arranged in the centre hole of left end cap 2, the right-hand member of spool 1 is movably arranged in the centre hole of right end cap 2, coil spring 4 is fixedly connected with the central outer arm of spool 1, coil spring 4 is provided with card line tongue 9 with the junction of spool 1, the external side end of coil spring 4 is fixedly connected with the medial surface of cylindrical tube 5, the central authorities of testing wire 6 are articulated on card line tongue 9, left end cap 2 and right end cap 3 are provided with line outlet 7 and 8.
During use, testing wire 6 is extracted out by line outlet 7 and 8, coil spring stressed rotation because of the rotation of pivot shaft 1 in extraction, testing wire 6 extracts length out when meeting the demands, testing wire 6 clamping can prevent it from rebounding under the application force of coil spring 1 by line outlet 7 and 8, unclamped by line outlet 7 and 8 after having tested, testing wire rebounds under the application force of coil spring 1.
Above embodiment only for illustration of the utility model, but not to restriction of the present utility model.Although be described in detail the utility model with reference to embodiment, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to the technical solution of the utility model, do not depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
