Technical Field

[0001] This utility model belongs to the field of insulation resistance testing technology, and specifically relates to an insulation resistance testing device. Background Technology

[0002] An insulation resistance testing device is a type of equipment used to measure the insulation resistance of various insulating materials, transformers, motors, and other electrical equipment. Chinese utility model patent CN219842449U discloses an insulation resistance testing device. This device includes a base, with an adjustment mechanism fixedly connected to the upper center of the base. A limit mechanism is fixedly connected to the upper end of the adjustment mechanism, and an insulation resistance tester is engaged with the upper end of the limit mechanism. Limit grooves are provided on the lower front and rear sides of the left and right ends of the insulation resistance tester. Connecting blocks are fixedly connected to the lower front and rear sides of the left and right ends of the limit mechanism. This utility model's insulation resistance testing device facilitates the installation and removal of the insulation resistance tester at the point of use, eliminating the need for personnel to hold the tester, thus improving testing efficiency. Furthermore, the height of the insulation resistance tester is easily adjustable to accommodate different working environments and personnel of varying heights.

[0003] The insulation resistance testing device disclosed in this application can support and position the insulation resistance tester by setting a base, adjusting mechanism and limiting mechanism, and the insulation resistance testing device can be adapted to different working environments and personnel of different heights by adjusting the height.

[0004] As can be seen from the description in the instruction manual and its accompanying drawings, although the base, adjustment mechanism and limiting mechanism can provide adjustable support and positioning for the insulation resistance tester, the design of these mechanisms reduces the portability of the insulation resistance tester, making it less convenient to use and carry.

The support top plate 301 provides support and fixation for the positioning seat 201.

[0036] like Figures 1 to 4 As shown, a supporting base plate 302 is provided below the supporting top plate 301. The supporting base plate 302 provides auxiliary support, positioning, and storage for the movable support rod 303 and the auxiliary support rod 304.

[0037] like Figure 1 As shown, a pair of lifting handles 305 are fixedly mounted on one side of both the top support plate 301 and the bottom support plate 302. The pair of lifting handles 305 facilitates the convenient lifting and handling of the top support plate 301 and the bottom support plate 302.

[0038] like Figures 2 to 4 As shown, a pair of movable support rods 303 are hinged to a first fixing plate 306 on the side away from the lifting handle 305. The first fixing plate 306 is fixedly connected to the inner wall of the supporting top plate 301. The first fixing plate 306 serves to fix and limit the movable support rods 303.

[0039] like Figures 2 to 4 As shown, a pair of movable support rods 303 and auxiliary support rods 304 are assembled between the top support plate 301 and the bottom support plate 302, and the movable support rods 303 and auxiliary support rods 304 are hinged together.

[0048] In practical use, when the insulation resistance tester 1 needs to be unfolded, the wheel rod 316 can be moved by manually turning it, so that the base plate 302 can be supported and positioned by multiple sets of wheel rods 316 and traveling wheels 317.

[0049] Subsequently, the threaded shaft 313 can be rotated by manually driving the rotating handle 314. Under the action of the internal and external threads, the linkage plate 312 drives a pair of active moving sliders 308 to slide within the supporting base plate 302. The movement of the moving support rod 303 is controlled by the active moving sliders 308 sliding along the guide slide rod 309. At the same time, the pair of auxiliary support rods 304 can be moved by the cooperation of the auxiliary moving slider 310 and the limit slide rod 311. By controlling the movement of the moving support rod 303 and the auxiliary support rod 304, the supporting top plate 301 can be raised and lowered, thus facilitating the adjustment of the insulation resistance tester 1 to a suitable height. Subsequently, the insulation resistance can be tested by the insulation resistance tester 1.

[0050] After use, the top plate 301 can be lowered and stored by rotating the handle 314 in the opposite direction. In addition, multiple sets of wheel rods 316 and traveling wheels 317 can be moved and stored by turning the wheel rods 316.
