Detailed Description
As shown in figure 1, the safety insulation resistance tester comprises a lower box body 1, wherein one end of the lower box body 1 is hinged with an upper box body 2 matched with the lower box body.
The inside of the lower box 1 is used for placing the tester body 3, and a certain gap is formed between the tester body 3 and the inner wall of the lower box 1. Four moving frames 4 are respectively arranged between the inner peripheral wall of the lower box body 1 and the outer peripheral wall of the tester body 3 in a sliding manner. In this embodiment, the lower box 1 is fixedly provided with L-shaped sliding frames 5 at four corners inside, each of the movable frames 4 is U-shaped, and two ends of each of the movable frames are respectively and fixedly provided with a connecting plate 6, and each of the connecting plates 6 is provided with a sliding hole adapted to the sliding frame 5.
Two clamping buffer blocks 7 are symmetrically arranged on one side, close to the lower box body 1, of each moving frame 4, specifically, two through holes are symmetrically formed in the middle position, corresponding to the two clamping buffer blocks 7, of each moving frame 4, and a movable rod 8 in clearance fit with the through holes is slidably arranged in each through hole. One end of each movable rod 8, which is close to the tester body 3, is fixedly connected with the clamping buffer block 7, a spring 9 is sleeved at a position, which is located between the moving frame 4 and the clamping buffer block 7, of each movable rod 8, and a limiting head 10, the diameter of which is larger than the inner diameter of the through hole, is fixedly arranged at one end, which is close to the inner wall of the lower box body 1, of each movable rod 8.
Threaded holes are respectively formed in the middles of four side walls of the lower box body 1, screw rods 11 in threaded connection with the threaded holes are installed in the threads, a rotating handle 12 is fixedly arranged at one end, located outside the lower box body 1, of each screw rod 11, and a butting head 13 used for butting one side, away from the tester body, of the corresponding movable frame 4 is fixedly arranged at one end, located inside the lower box body 1.
In practical application, the screw rod is rotated by screwing the rotating handle, and the screw rod is in threaded connection with the threaded hole in the side wall of the lower box body, so that the screw rod can do linear motion along the axial direction in the rotating process, and the abutting head at one end of the screw rod, which is positioned in the lower box body, can push the moving frame to move towards the direction of the tester body after abutting against the moving frame. The stable centre gripping to the tester body is realized through four pairs of tight buffer blocks of clamp in four directions like this, and the tester body can not produce the gross movement relatively the box when receiving exogenic action or dropping, avoids causing colliding with and damaging the tester, guarantees the security performance and the life of insulation resistance tester.
When the tester body needs to be taken out of the box body, the rotating handle is reversely screwed, and each pair of clamping buffer blocks is far away from the tester body.
