[0026] As Figures 1-4 shown, the voltage withstand testing device in the utility model is similar to the existing test support structure, such as a kind of auxiliary device for cable voltage withstand test, the main improvement point of the utility model is that the motor roller 305 winding is arranged at the both ends of belt 303, cooperate with internal controller 306 and bluetooth connection to realize the cable collection and fixation under non-contact, while cooperate with antiskid strip 304 to improve the friction under collection, keep the stability during cable test process;Bluetooth module 307 and controller 306 in the utility model are prior art, when using this voltage withstand testing device, the device structure can be placed by the bottom disc frame 101 at the bottom end of structure, while the counterweight 103 embedded in the center of bottom disc frame 101 can keep the center stability of the whole device bottom placement, and cooperate with the rubber disc 102 on the bottom surface to adhere to the placement environment, keep the bottom insulation and test stability.

[0027] Through the counterweight 103 embedded in the bottom disc frame 101, the stability of the device is increased, and the problem of device inclination or instability caused by vibration or external interference during the test process is avoided. At the same time, the design of counterweight 103 ensures that the whole device remains balanced during the test process, enhancing the safety of operation;The rubber disc 102 attached to the bottom surface of the bottom disc frame 101 provides good anti-skid effect, which can effectively avoid errors or instability caused by bottom sliding during the test process. In addition, the rubber disc 102 can provide additional insulation protection to ensure the safety of the operator during the cable voltage withstand test.

[0028] Through the winding function of motor roller 305 and belt 303, cooperate with controller 306 and bluetooth module 307, the non-contact collection and fixation of cable is realized. This way avoids the damage or interference to cable that may be caused by traditional contact type fixation, improves the accuracy and reliability of test;The use of antiskid strip 304 increases the friction during cable collection process, ensures that the cable remains stable during the test process, prevents the cable from sliding or deviating, further improves the accuracy of test.

[0029] Through bluetooth connection and controller 306, users can conveniently control the device remotely, realize cable collection and fixation. The integration of control system improves the flexibility and convenience of operation;The bluetooth module 307 and controller 306 in the voltage withstand testing device adopt existing technology, which is convenient for compatibility with other equipment and reduces the difficulty of technical implementation.

[0030] As shown in Figures 1-2 , the adjusting frame 2 includes a support rod 201, and the inner wall of the support rod 201 is sleeved with a telescopic rod 202. The top end of the telescopic rod 202 is connected with a threaded pile 203, and the top end of the threaded pile 203 is connected with a pedestal 310. The bottom end of the telescopic rod 202 is sleeved with a threaded rod 204, and the bottom end of the threaded rod 204 is connected with a motor frame 205. In the use of the test device, the threaded rod 204 connected with the shaft center can be driven to rotate by the motor frame 205.

The threaded pile 203 at the top end of the telescopic rod 202 is connected with the pedestal 310, which drives the pedestal 310 to be adjusted up and down synchronously, providing height adjustment for the fixed cable position.

[0031] The rotation of the threaded rod 204 drives the telescopic rod 202 to rise and fall, which can realize the accurate height adjustment of the pedestal 310. The threaded structure provides higher adjustment accuracy, so that the fixed position of the cable can be accurately aligned, avoiding the error of the traditional mechanical adjustment mode, and ensuring the accuracy in the test process. The telescopic rod 202 rises and falls along the track slot in the support rod 201, which can provide smooth movement by the rotation of the threaded rod 204. This design reduces the error caused by vibration or unstable adjustment, so that the cable can maintain a stable position during the voltage test, avoiding the influence caused by the shaking or instability of the device.

[0032] The cooperation of the motor frame 205 and the threaded rod 204 enables the adjustment process to be automated without human intervention.

Users can adjust according to the length and test requirements of different cables, increasing the adaptability and versatility of the device. By accurately adjusting the height and position of the cable, the distance between the cable and other equipment during the test can be maintained properly, reducing the risk of contact between the cable and the test device or other hardware, thereby improving the safety of operation.

[0036] The anti-skid strip 304 on the inner wall of the belt 303 is made of rubber material, which has good friction and can ensure insulation in a high-voltage environment. This is very important for cable pressure test, which can prevent current leakage or cable sliding and enhance the safety and stability of the equipment; the top table 301 can adjust the angle through the rotating shaft 308, which can adjust the test position according to the test requirements of different cables and increase the adaptability of the device. The spring piles 309 around the rotating shaft provide elastic buckling, so that the adjusted angle can be fixed at the required position to maintain the stability and accuracy during the test.

[0037] The motor roller and the collection structure controlled by Bluetooth can easily adjust the fixing degree of the cable without manual adjustment of the device. The automatic design improves the test efficiency, reduces human intervention, and reduces errors or instability caused by improper operation.
