[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of an automatic auxiliary device for a resistance tester, including a detection chamber 1, a rotating connecting shaft 803, and a fixing assembly. A detection base 2 is located at the bottom of the detection chamber 1, and a control panel 3 is located inside the detection base 2. A temperature monitor 4 is located on the left side of the detection chamber 1. A movable connecting seat 5 is slidably connected inside the detection chamber 1, and an observation window 6 is located inside the movable connecting seat 5. The fixing assembly is located inside the movable connecting seat 5. The rotating connecting shaft 803 is rotatably connected inside the movable connecting seat 5, and the external rotating connecting shaft 803 is... A first gear 804 is connected to the movable connecting seat 5. A rotating threaded rod 805 is rotatably connected inside the movable connecting seat 5. A second gear 806 is fixedly connected to the outside of the rotating threaded rod 805. A threaded connecting sleeve 807 is threadedly connected to the outside of the rotating threaded rod 805 and is fixedly connected to the bottom of the movable connecting seat 5. Rotation of the rotating threaded rod 805, coupled with the threaded connection between the rotating threaded rod 805 and the threaded connecting sleeve 807, pushes the movable connecting seat 5 to slide inside the detection chamber 1. A control panel 3 is used to control the operating status of the equipment, and a temperature monitoring instrument is also included. 4 is used to monitor the temperature inside the detection chamber 1. The observation window 6 is used to observe the internal resistance. Rotation of the connecting shaft 803 drives the first gear 804 to rotate. The first gear 804 meshes with the second gear 806, causing the rotating threaded rod 805 to rotate inside the movable connecting seat 5. The rotation of the threaded rod 805, in conjunction with the threaded connection of the threaded connecting sleeve 807, pushes the movable connecting seat 5 to slide inside the detection chamber 1, thus sealing the detected resistance. The detection chamber 1, in the movable connecting... A groove is provided at the corresponding position of the seat 5, and the movable connecting seat 5 slides inside the groove. The groove provided inside the detection box 1 at the position corresponding to the movable connecting seat 5 limits the sliding of the movable connecting seat 5 in the groove. The support connecting shell 801 is provided with a groove at the meshing position of the first gear 804 and the second gear 806, so that the first gear 804 and the second gear 806 can be meshed and connected. The groove provided in the support connecting shell 801 at the meshing position of the first gear 804 and the second gear 806 allows the first gear 804 and the second gear 806 to be effectively meshed and connected.

[0021] Please see Figure 2 - Figure 3In this embodiment, a support connecting shell 801 is disposed inside the movable connecting seat 5. A fixed drive motor 802 is disposed on the top of the support connecting shell 801. An electric telescopic rod 809 is fixedly connected inside the detection box 1. A fixed compression ring 810 is disposed on the front of the electric telescopic rod 809. The fixed compression ring 810 is fixedly connected inside the movable connecting seat 5. A terminal block 808 is disposed inside the movable connecting seat 5. The electric telescopic rod 809 extends and retracts inside the detection box 1, and the fixed compression ring 810 drives the movable connecting seat 5 to extend and retract inside the detection box 1. Two electric telescopic rods 809 are disposed, and the two electric telescopic rods 809 are symmetrically fixedly connected inside the detection box 1. The two electric telescopic rods 809 make the fixed compression ring 810 stable when pulling the movable connecting seat 5.

[0022] Please see Figure 4 - Figure 5 In this embodiment, the fixing assembly includes a connecting slide rail 901, which is fixed to the top of the movable connecting seat 5. A fixing bracket 902 is fixedly connected to the top of the connecting slide rail 901. A limit rod 903 is fixedly connected to the inner side of the fixing bracket 902. A sliding fixing block 905 is slidably connected to the outer side of the limit rod 903. A fixing device 904 is fixedly connected to the inner side of the sliding fixing block 905. The fixing device 904 slides inside the connecting slide rail 901. A fixing conical groove 906 is formed inside the fixing device 904. The bottom of 04 is fixedly connected with a guide column 907. The sliding fixing block 905 is slid to a suitable position in the groove of the connecting slide rail 901 under the limit of the limiting rod 903 according to the distance of the resistor wire. The resistor wire is inserted and fixed through the fixing conical groove 906. The connecting slide rail 901 has a groove at the corresponding position of the fixing device 904. The fixing device 904 is limited when sliding in the groove. The groove opened in the connecting slide rail 901 corresponding to the position of the fixing device 904 limits the fixing device 904 when sliding in the groove.

[0023] During operation, the sliding fixing block 905, limited by the limiting rod 903, slides to a suitable position in the groove of the connecting slide rail 901 according to the distance of the resistor wire. The resistor wire is then inserted and fixed through the fixing conical groove 906. After the resistor is fixed inside the movable connecting seat 5, the rotating connecting shaft 803 is driven to rotate inside the movable connecting seat 5 by the supporting connecting shell 801. The rotation of the rotating connecting shaft 803 drives the first gear 804 to rotate. The first gear 804 meshes with the second gear 806, causing the rotating threaded rod 805 to rotate inside the movable connecting seat 5. The rotation of the rotating threaded rod 805 engages with the threaded connecting sleeve 807 to push... The movable connecting seat 5 slides inside the detection chamber 1, so that the movable connecting seat 5 cooperates with the detection chamber 1 to seal the resistor being detected. Then, the electric telescopic rod 809 extends and retracts inside the detection chamber 1, and the fixed compression ring 810 drives the movable connecting seat 5 to extend and retract inside the detection chamber 1 to achieve closure. The temperature inside the detection chamber 1 is controlled by the control panel 3 and detected by the temperature monitoring instrument 4. The detection frame clamps the terminal 808 to input current. The current is transmitted through the terminal 808 to the guide column 907, and then through the guide column 907 to the fixed conical groove 906, and finally through the fixed conical groove 906 to the wire of the resistor for detection.

[0024] Through the above steps, the supporting connecting shell 801 drives the rotating connecting shaft 803 to rotate inside the movable connecting seat 5. The rotation of the rotating connecting shaft 803 drives the first gear 804 to rotate. The first gear 804 meshes with the second gear 806 and rotates, driving the rotating threaded rod 805 to rotate inside the movable connecting seat 5. The rotation of the rotating threaded rod 805 and the threaded connection of the threaded connecting sleeve 807 push the movable connecting seat 5 to slide inside the detection box 1. This allows the movable connecting seat 5 to cooperate with the detection box 1 to seal the resistance being tested. This solves the problem that when the automatic auxiliary device of the resistance tester is performing a test, the resistance is exposed to the outside, and the difference in external temperature and humidity may affect the resistance test effect and reduce the accuracy of the resistance test.
