The rotating arm 13 rotates on one side of the sliding column 8, and the rotating connection enables the rotating arm 13 to flexibly change the angle to adapt to different working conditions, thereby improving the effect and stability of fixing the tire.

[0037] Reference Figure 4 、 Figure 5 The Y-shaped block 18 is fixedly connected to the driving end of the air pump 16. This connection method enables the air pump 16 to accurately control the movement of the Y-shaped block 18, thereby achieving precise fixation of the valve mouth. The outside of the sliding wheel 22 contacts the top of the Y-shaped block 18, and the bottom of the placement block 27 contacts the top of the slide rod 28. This contact ensures the position stability of the placement block 27 on the slide rod 28, so that it can stably support the pressure detection device 25. The outside of the slide rod 28 contacts the inner wall of the support body 26. This close contact ensures the accuracy and stability of the sliding of the slide rod 28 in the support body 26, so that the position of the placement block 27 can be accurately adjusted.

[0038] Working principle: When the air tightness of the tire needs to be tested, the tire is placed on the top of the placement plate 14. At this time, the hydraulic cylinder 11 is started to drive the push plate 12 to move, and the push plate 12 moves while driving the rotating arm 13 to rotate. When the rotating arm 13 rotates, it drives the slider 9 to slide on the outside of the slide column 8. A clamping block 10 is provided on the top of the slide column 8, which drives the clamping block 10 to slide, so that the tire can be clamped and fixed, and can prevent the tire from moving or shaking during the measurement process. At this time, the tire valve is placed on the top of the support block 15, and the air pump 16 is started at this time, which drives the Y-shaped block 18 to move upward. When the Y-shaped block 18 moves upward, the sliding wheel 22 at the bottom end of the rotating rod 20 will slide on both sides of the Y-shaped block 18, thereby driving the rotating rod 20 to rotate.

[0039] A sliding wheel 21 is provided on the top of the rotating rod 20, which can fix valves of different sizes, reduce pressure fluctuations caused by unstable connection, and make the measurement data more reliable and consistent. At this time, the electric air pump 23 inside the box 1 is started to detect the air tightness of the tire, and then measure the pressure through the pressure detection device 25 outside the air pipe 24, so that the air tightness of the tire can be measured, and then the data can be read through the pressure detection device 25. When testing, the placement block 27 is rotated, and the placement block 27 can be supported by the sliding rod 28, and the pressure detection device 25 can be supported by the placement block 27. When testing is required, the placement block 27 is rotated upward, and then the right end of the placement block 27 is inserted into the support body 26, and then the pressure detection device 25 is placed inside the right side of the box 1, so that the working space of the box 1 can be increased.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
