At present, because the electronic component in the insulation resistance tester is more, when it received jolting in carrying the transportation, the condition that the insulation resistance tester damaged appears very easily, influences the use of insulation resistance tester to at the in-process that the insulation resistance tester used, because it is longer to detect the wire, the chaotic condition of wire appears very easily, influence the accuracy that the insulation resistance tester detected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an insulation resistance tester to solve because the electronic component in the insulation resistance tester is more, when receiving jolting in it carries the transportation, the condition that insulation resistance tester damaged appears very easily, influences insulation resistance tester's use, and at the in-process that insulation resistance tester used, because it is longer to detect the wire, the chaotic condition of wire appears very easily, influences the problem of the accuracy that insulation resistance tester detected.

In order to achieve the above object, the utility model provides a following technical scheme: insulation resistance tester, including protecting the box, dead lever and spring are installed to the bottom of protecting the box, the spring housing is established on the dead lever, the buffer board is installed to the upper end of spring, install tester body and baffle on the buffer board.

Preferably, be equipped with flexible groove in the dead lever, flexible inslot cover is equipped with the telescopic link, and the upper end of telescopic link is installed on the buffer board, restrict the distance that the tester body reciprocated through flexible groove and telescopic link, avoid appearing the condition that the tester body strikes on the protection box lid.

Preferably, install the spool between protection box and the baffle, all be equipped with the circular port on the inner wall of baffle and protection box, the both ends of spool are all rotated and are installed in the circular port, and the one end of spool runs through the protection box, and the knob is installed to the one end that the spool wore out, is convenient for control the spool through the knob and rotates, be equipped with the winding displacement hole on baffle and the spool.

Preferably, the interior test wire that draws of tester body, the winding hole is passed to the one end of test wire, and the test wire winding on the winding reel, rotates through the control winding reel, can control receiving, putting of test wire to can control the length of test wire as required, avoid appearing the longer condition that leads to the wire confusion of test wire.

Preferably, the number of baffle is two, and the baffle will two collection wire casing and mounting groove are separated out in the protection box, and the spool all is located collection wire casing with the test wire, and the tester body is yellow besom in the mounting groove.

Compared with the prior art, the beneficial effects of the utility model are that: the tester body extrudes the spring through the buffer plate, so that the tester body moves up and down under the elastic force of the spring, the anti-vibration force generated by bumping of the tester body can be removed, and the condition that electronic elements in the tester body are damaged is avoided; receive, put through the take-up of hank control test wire to can control test wire's length as required, avoid appearing the longer condition that leads to the wire confusion of test wire.

Drawings

Fig. 1 is a top view of the overall structure of the present invention;

FIG. 2 is a front cross-sectional view of the overall structure of the present invention;

fig. 3 is a front cross-sectional view of the fixing rod of the present invention.

In the figure: 1 protection box, 2 dead levers, 3 springs, 4 buffer boards, 5 tester bodies, 6 baffles, 7 telescopic slots, 8 telescopic links, 9 spools, 10 knobs, 11 test wires, 12 winding holes, 13 winding grooves and 14 mounting grooves.

Detailed Description

Referring to fig. 2, the insulation resistance tester includes a protection box 1, a fixing rod 2 and a spring 3 are installed at the bottom of the protection box 1 through screws, the spring 3 is sleeved on the fixing rod 2, a buffer plate 4 is installed at the upper end of the spring 3 through a screw, and a tester body 5 and a partition plate 6 are installed on the buffer plate 4 through screws.

Please refer to fig. 2 and 3, a telescopic slot 7 is arranged in the fixing rod 2, a telescopic rod 8 is sleeved in the telescopic slot 7, the upper end of the telescopic rod 8 is mounted on the buffer board 4 through a screw, and the distance of the tester body 5 moving up and down is limited through the telescopic slot 7 and the telescopic rod 8, so as to avoid the situation that the tester body 5 collides with the box cover of the protection box 1.

Referring to fig. 1 and 2, a winding reel 9 is installed between a protection box 1 and a partition plate 6, circular holes are formed in the inner walls of the partition plate 6 and the protection box 1, two ends of the winding reel 9 are rotatably installed in the circular holes, one end of the winding reel 9 penetrates through the protection box 1, a knob 10 is installed at one end, through which the winding reel 9 penetrates out, of the winding reel 9 through a screw, the rotation of the winding reel 9 is conveniently controlled through the knob 10, and a wire arranging hole 12 is formed in the partition plate 6 and the winding reel 9.

Referring to fig. 1 and 2, a test wire 11 is led out from the tester body 5, one end of the test wire 11 passes through the wire arranging hole 12, and the test wire 11 is wound on the winding shaft 9, and the winding and unwinding of the test wire 11 can be controlled by controlling the rotation of the winding shaft 9, so that the length of the test wire 11 can be controlled as required, and the condition that the test wire 11 is long and the wire is disordered is avoided.
