[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Such as Figures 1-4As shown in the figure, an auxiliary device for measuring the insulation resistance of a controller includes a tester main body 1; a cover plate 11 is hinged to the top of the tester main body 1; two groups of rotating shafts 12 are rotatably connected to the outer wall of the tester main body 1; a tooth block 13 is fixedly connected to the middle of the rotating shaft 12; the middle of the output end of the cover plate 11 is rotatably connected to a belt 14, and the other end of the belt 14 is rotatably connected to the middle of the rotating shaft 12; a sliding plate 15 is slidably connected to the inner wall of the tester main body 1; a tooth rail 16 is fixedly connected to the side wall of the sliding plate 15, and the tooth rail 16 and the tooth block 13 are meshed with each other; a rubber cushion plate 17 is fixedly connected to the middle of the sliding plate 15; during operation, the staff can hold the middle of the tester main body 1, transfer the tester main body 1 to the designated working area, and then flip the middle of the cover plate 11. By arranging two slidable sliding plates 15 on the inner wall of the tester main body 1, when the cover plate 11 rotates, the belt 14 arranged can synchronously drive the whole tooth block 13 to rotate. When the cover plate 11 is opened, the tooth block 13 can push the sliding plate 15 and the tooth rail 16 to move outwards, and present the rubber cushion plate 17 to the outside. Then, the staff can place the controller to be measured on the top of the rubber cushion plate 17 and preliminarily fix the controller by means of its uneven surfaces. Then, start the switch of the tester main body 1 and cooperate with the measuring probe to measure the resistance of the controller. After the measurement is completed, the cover plate 11 can be closed, and the rubber cushion plate 17 can be received at the bottom of the tester main body 1 again by the reversely rotating tooth block 13. This step, combined with the arranged rubber cushion plate 17, can improve the flatness of the placement plane when measuring the controller. And under the action of the uneven rubber cushion plate 17, the friction force between the controller and the rubber cushion plate 17 during placement can be increased, reducing the problem that when the controller is directly placed on the ground and the controller moves or slides due to the end of the pusher during the measurement of the controller, thus affecting the accuracy and reliability during measurement. When the cover plate 11 is closed, it can receive the whole tooth rail 16 and reduce the overall occupied space of the tester main body 1.

[0026] As Figures 2-3As shown, multiple groups of card holes 2 are provided in the middle of the rubber cushion plate 17; a sliding groove 21 is provided in the middle of the card hole 2; a card pin 22 is slidably connected to the inner wall of the sliding groove 21; a connecting frame 23 is fixedly connected to the middle of the card pin 22; a counterweight 24 is fixedly connected to the bottom of the connecting frame 23; during work, by providing multiple groups of card holes 2 in the middle of the rubber cushion plate 17, when the controller is placed on the top of the rubber cushion plate 17, the gravity generated by the two connecting frames 23 as a whole will fix its end. When fixing controllers of different lengths, the staff can pull up the two connecting frames 23 in sequence. After the card pin 22 is separated from the inner wall of the card hole 2, the connecting frame 23 can be pulled left and right, and the connecting frame 23 can slide on the inner wall of the sliding groove 21. After adjusting the connecting frame 23 to a specified position, the connecting frame 23 can be released and under the action of the counterweight 24, the connecting frame 23 will fall and squeeze and fix the edge of the controller. This step, combined with the two sets of connecting frames 23 provided, can further improve the stability when measuring the controller, reduce the phenomenon of the controller shifting in position, and combined with multiple groups of card holes 2 provided, can improve the flexibility of the two connecting frames 23 during work, and reduce the problem that the connecting frame 23 can only fix the middle of the controller, resulting in occlusion during subsequent measurement.

[0027] As Figure 1 and 4 shown, two sets of vertical blocks 3 are fixedly connected to the side wall of the tester main body 1; a screw rod 31 is threadedly connected to the middle of the vertical block 3; the end of the screw rod 31 is rotatably connected to a support plate 32, and the support plate 32 is slidably arranged on the outer wall of the tester main body 1; a limiting frame 33 is fixedly connected to the middle of the support plate 32, and the belt 14 is arranged inside the limiting frame 33; during work, by providing two sets of vertical blocks 3 on the outer wall of the tester main body 1, when the tightness of the belt 14 needs to be adjusted, the staff can rotate the two screw rods 31, and the screw rods 31 can push the whole support plate 32 to move up and down, and squeeze the middle of the belt 14 so that the limiting frame 33 contacts the middle of the belt 14. This step, combined with the support plate 32 provided, can prevent the belt 14 from loosening after long-term use, and the tension and friction between the belt 14 and the output ends of the rotating shaft 12 and the cover plate 11 are low, resulting in jamming during subsequent transmission and affecting the subsequent transmission efficiency, and improve the flexibility of the whole belt 14 during use.

[0028] As Figure 3As shown, a support plate 4 is fixedly connected to the middle of the connecting frame 23; a plurality of gaskets 41 are fixedly connected to the bottom of the support plate 4; during operation, by arranging two support plates 4 in the middle of the connecting frame 23, when the connecting frame 23 drops and contacts the controller, a plurality of support plates 4 will first approach the middle of the controller, and cooperate with the gaskets 41 made of soft material to contact the controller. In this step, under the action of the support plate 4, the contact area when contacting the controller can be increased, and the plurality of gaskets 41 made of soft material can protect the edge of the controller and reduce the wear on the controller.

[0029] As Figure 4 shown, a support rod 5 is fixedly connected to the end of the rotating shaft 12; a flexible rod 51 is fixedly connected to the middle of the support rod 5; during operation, by arranging a support rod 5 at the end of the rotating shaft 12, when the rotating shaft 12 rotates, it will drive the support rod 5 to rotate synchronously, and the bent flexible rod 51 will beat the middle of the belt 14. After the rotating shaft 12 rotates, the middle of the flexible rod 51 will deform and cross over the middle of the belt 14 and then reset again. This process is repeated. With the cooperation of the flexible rod 51 arranged, the cleanliness of the middle of the belt 14 can be improved, and the problem that when the tester main body 1 is used outdoors for a long time, a large amount of impurities accumulate on the surface of the belt 14, resulting in too fast aging speed, can be reduced.

[0030] As Figure 4 shown, two rotating wheels 6 are rotatably connected to the middle of the limiting frame 33, and the middle of the rotating wheels 6 is in contact with the middle of the belt 14; during operation, by arranging two rotating wheels 6 in the middle of the limiting frame 33, when the belt 14 moves, under the action of friction, it can drive the rotating wheels 6 to rotate. With the cooperation of the rotating wheels 6 arranged, the wear on the middle of the belt 14 can be reduced and its service life can be extended.

[0031] As Figure 2 shown, a friction member 7 is fixedly connected to the middle of the connecting frame 23; during operation, by arranging the uneven friction member 7 in the middle of the connecting frame 23, when the staff pulls or places the connecting frame 23, their hands will first contact the friction member 7. In this step, under the action of the friction member 7, the hands of the staff can be in deep contact with the friction member 7, and the problem of hand slipping during the process of pulling the connecting frame 23 can be reduced.

[0032] Working principle: After transferring the tester main body 1 to the designated working area, the middle part of the flip cover plate 11 will be turned over. By arranging two sets of slidable slide plates 15 on the inner wall of the tester main body 1, when the cover plate 11 rotates, the belt 14 arranged in cooperation can drive the whole tooth block 13 to rotate synchronously. And when the cover plate 11 is opened, the tooth block 13 can push the slide plate 15 and the tooth rail 16 to move outwards, and present the rubber cushion plate 17 to the outside. Then the staff can place the controller to be measured on the top of the rubber cushion plate 17 and initially fix the controller by means of its uneven surfaces. Then, start the switch of the tester main body 1 and cooperate with the measuring probe to measure the resistance of the controller. After the measurement is completed, the cover plate 11 can be closed, and the rubber cushion plate 17 can be received at the bottom of the tester main body 1 again by the reversely rotating tooth block 13. By arranging multiple sets of card holes 2 in the middle of the rubber cushion plate 17, when the controller is placed on the top of the rubber cushion plate 17, the gravity generated by the two connecting frames 23 will fix the end of the controller. When fixing controllers of different lengths, the staff can pull up the two connecting frames 23 in sequence. After the pin 22 is separated from the inner wall of the card hole 2, the connecting frame 23 can be pulled left and right, and the connecting frame 23 can slide on the inner wall of the chute 21. After adjusting the connecting frame 23 to the designated position, the connecting frame 23 can be released and under the action of the counterweight 24, the connecting frame 23 will fall and squeeze and fix the edge of the controller. By arranging two sets of vertical blocks 3 on the outer wall of the tester main body 1, when the tightness of the belt 14 needs to be adjusted, the staff can rotate the two screw rods 31, and the screw rods 31 can push the whole supporting plate 32 to move up and down, and squeeze the middle part of the belt 14, so that the limiting frame 33 contacts with the middle part of the belt 14. By arranging two sets of supporting plates 4 in the middle of the connecting frame 23, when the connecting frame 23 falls and contacts the controller, multiple supporting plates 4 will first approach the middle of the controller, and contact the controller with the gasket 41 made of soft material. By arranging a support rod 5 at the end of the rotating shaft 12, when the rotating shaft 12 rotates, the support rod 5 will rotate synchronously, and the bent soft rod 51 will beat the middle part of the belt 14. After the rotating shaft 12 rotates, the middle part of the soft rod 51 will deform and cross over the middle part of the belt 14 and then reset again, repeating this process. By arranging two sets of rotating wheels 6 in the middle of the limiting frame 33, when the belt 14 moves, under the action of friction, it can drive the rotating wheels 6 to rotate. By arranging an uneven friction part 7 in the middle of the connecting frame 23, when the staff pulls or places the connecting frame 23, their hands will first contact the friction part 7.
