[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 4 As shown, an insulation resistance tester with a protection mechanism provided by an embodiment of the utility model includes:

[0031] A placement box 1 is provided with clamping assemblies 3 on both sides thereof. First, the two sets of clamping assemblies 3 are opened, and then the tester body 8 is placed inside the placement box 1, and then the clamping assemblies 3 are released, so that the two sets of clamping assemblies 3 clamp the tester body 8, thereby fixing the tester body 8 so that it is not easy to fall off from the placement box 1.

[0032] Hinges 6 are fixedly installed on both sides of one end of the placement box 1, and a cover plate 7 is fixedly installed between the two sets of hinges 6. After the tester body 8 is placed on the placement box 1, the cover plate 7 is flipped to make the hinge 6 drive the cover plate 7 to close the placement box 1, and then the cover plate 7 is fixed by other components. In this way, the placement box 1 can be placed in an idle position, which plays the effect of protecting the tester body 8 from external damage when idle.

[0033] Docking blocks 5 are fixedly installed on both ends of the side walls of the cover plate 7, and snap-on components 4 are fixedly installed on both sides of the other end of the placement box 1. The snap-on components 4 include two groups of sliding columns 403 and a fixed block 401. A square hole is opened on the upper surface of the fixed block 401, and the sliding column 403 is arranged in the square hole. A hook 405 is fixedly installed on one end of the sliding column 403, and the hook 405 is snap-fitted with the docking block 5. After the cover plate 7 closes the placement box 1, the hook 405 is inserted into the docking block 5, and then the sliding column 403 is released to make the sliding column 403 and the hook 405 rebound to their original positions. The hook 405 is snap-fitted in the docking block 5, which can fix the cover plate 7 and prevent the cover plate 7 from being easily opened.

[0034] The tester body 8 is detachably connected to the placement box 1, and the tester body 8 is located between the two sets of clamping components 3. The tester body 8 is placed inside the placement box 1, and the clamping components 3 and the cover plate 7 inside the placement box 1 protect the tester body 8.

[0035] There are circular holes on both sides of the fixing block 401, and through holes are opened in the circular holes, and the through holes are communicated with the square holes. The sliding column 403 is slidably connected with the through holes. Through the sliding cooperation between the sliding column 403 and the through holes, the hook 405 can be retracted back and forth.

[0036] A slot 11 is provided on the lower surface of the docking block 5, and snap-in slots 12 are provided on both sides of the slot 11. The hook 405 is snap-fitted with the snap-in slot 12. When the cover plate 7 needs to be covered, the hook 405 is first inserted into the slot 11, and then the hook 405 is expanded outward and snapped into the snap-in slot 12, thereby fixing the cover plate 7.

[0037] The clamping assembly 4 also includes a button 402 and a second spring 404, the second spring 404 is fixedly installed in the circular hole, the sliding column 403 is located at the center end of the second spring 404, the button 402 is fixedly installed on one side of the sliding column 403, one end of the second spring 404 is fixedly connected to the inner wall of the circular hole, and the other end of the second spring 404 is fixedly connected to one end of the button 402. First, the button 402 is pressed and then the second spring 404 is squeezed, the two groups of sliding columns 403 move toward each other, and the two groups of hooks 405 are in a close contact state. Then the cover plate 7 covers the placement box 1, and the hooks 405 are just inserted into the notches 11 of the docking block 5. Then the button 402 is released again. Under the rebound of the second spring 404, the button 402 drives the sliding column 403 to slide quickly to its original position, and the sliding column 403 quickly unfolds with the hook 405, and the hook 405 is clamped in the clamping groove 12, so that the cover plate 7 is fixed.

[0038] Holes are provided on both sides of the placement box 1, and the holes are communicated with the inner wall of the placement box 1. Two groups of grooves 10 are provided on both sides of the interior of the placement box 1, and slide grooves 9 are provided at the upper and lower ends of the grooves 10. A handle 2 is fixedly installed at one end of the two groups of placement boxes 1, and the handle 2 is used to lift the placement box 1 for easy carrying of the placement box 1.

[0039] The clamping assembly 3 includes a connecting column 302, which is slidably inserted into the hole, and one end of the connecting column 302 is located inside the placement box 1. A handle 301 is fixedly installed on the side wall of the connecting column 302. The handle 301 and the connecting column 302 are connected in a T-shape. A clamping block 309 is fixedly installed at one end of the connecting column 302. Both ends of the clamping block 309 are provided with a rotating shaft hole. Before the tester body 8 is placed, the handle 301 is first pulled, and then the connecting column 302 is dragged to slide outward in the hole, and then the connecting column 302 drives the clamping block 309 to move together.

[0040] The first spring 303 is fixedly installed on both ends of the side wall of the clamping block 309, one end of the first spring 303 is fixedly connected to the inner wall of the placement box 1, and the second shaft 308 is rotatably connected in the shaft hole. After the two groups of clamping blocks 309 are close to the inner wall of the placement box 1, the tester body 8 is then placed in the placement box 1, and then the handle 301 is released, and then the first spring 303 pushes the clamping block 309 to move toward the tester body 8. The first spring 303 applies a reverse force to the clamping block 309 under the action of its own elasticity, so that the clamping block 309 applies force to the tester body 8, which is convenient for fixing and clamping tester bodies 8 of different sizes. When a collision occurs, the first spring 303 can also play a certain buffering role to reduce damage to the tester body 8.

[0041] The clamping assembly 3 also includes a slider 304, which is slidably connected in the slide groove 9. The slider 304 plays a role of stable support when the clamping block 309 moves. Fixed plates 305 are fixedly installed at both ends of the side walls of the slider 304. A rotating block 306 is rotatably connected between the two groups of fixed plates 305. A first rotating shaft 307 is provided between the fixed plate 305 and the rotating block 306. The rotating block 306 is rotatably connected to the fixed plate 305 through the first rotating shaft 307, and the rotating block 306 is rotatably connected on the surface of the second rotating shaft 308 at one end of the rotating block 306. The two groups of sliders 304 move toward each other, thereby driving the rotating block 306 to move. During the movement, both ends of the rotating block 306 rotate, thereby providing a certain supporting force for the clamping block 309, so that the clamping block 309 can further clamp the tester body 8, further reducing damage to the tester body 8.
