The working principle and use process of the utility model are as follows: first, the tire 5 to be tested is installed on the connecting column 4 to ensure that the tire 5 matches the tire puncture assembly. Then, the slider 3 is slid to the appropriate position of the slide rail 2 so that the tire 5 is located in the test area. The various parameters of the test, such as the test speed and the number of punctures, are set through the control box 18. The operator controls the slide bar 7 through the handle 9 to move the slider 3 along the slide rail 2 to send the tire 5 into the test area. Then, the motor 11 is started to start the puncture resistance test. During the test, the tire puncture assembly including the bracket 13, the bottom plate 14, the cylinder 16 and the puncture plate 17 will simulate the scene of the tire being punctured under different conditions. According to the preset parameters, the puncture plate 17 will repeatedly puncture and pull out the tire 5 to test its puncture resistance performance. During the test, the control box 18 will collect data such as the pressure change of the tire 5 during the puncture and pull out process, the position and speed of the puncture plate 17. These data can be used to analyze the puncture resistance performance of the tire and provide a basis for tire design and production. After the test is completed, the operator can stop the test through the control box 18. Then, slide the slider 3 to the appropriate position of the slide rail 2 and move the tire 5 out of the test area. The operator can view the test results through the display screen on the control box 18, and can export the results as a report for subsequent analysis and reference. If different types of tires need to be tested, the tire 5 can be easily replaced, and then the above steps can be repeated for testing. If the test device is damaged or worn during use, corresponding repairs and maintenance can be carried out to ensure the normal operation of the test device. By using the slide rail 2, the slider 3 and the moving mechanism including the toothed plate 10, the motor 11 and the gear 12, the tire 5 can be accurately moved and positioned in the test area. This makes the test process more stable and accurate, and improves the test accuracy.
