Description

Technical Field

[0001] This utility model relates to the field of tire testing technology, specifically a device for testing the air tightness of vacuum tires. Background Technology

[0002] Tire quality is crucial for ensuring the safety of both motor vehicles and non-motor vehicles, and tire strength and airtightness are essential factors in ensuring safe tire use. Since tire airtightness is related to its structure, compound, and manufacturing process, and new tires vary due to differences in raw material batches and manufacturing processes, it is necessary to test the strength and airtightness of the molded and vulcanized tires. This testing is required to rate the material strength and detect the presence of cracks, pores, or nail holes, necessitating the use of a tubeless tire airtightness testing device.

[0003] The commonly used method for testing tire air tightness is to place the tire in a basin filled with water and then manually rotate the tire to find the leak. This method increases the labor intensity of the workers, and the operators need to be in close contact with the high-pressure tire during the test. If the tire suddenly bursts during the test, the flying fragments can easily cause personal injury. Therefore, a vacuum tire air tightness testing device is proposed to solve the above-mentioned technical problems. Utility Model Content

[0018] In summary, this tubeless tire airtightness testing device, through the testing component 4, places the tubeless tire on the connecting shaft 45, and then fixes the tubeless tire with the anti-loosening positioning nut 46. At this time, the electric push rod 41 is activated to drive the connecting plate 42 to move down, so that the lower half of the tubeless tire is immersed in the water tank 5. The transparent water tank 5 and the protective cover 64 design ensure that the testing process is fully visible. With the drive motor 44 rotating the tire at a uniform speed, the air bubbles generated at the leakage point are clearly visible in the water. No manual rotation is required, reducing the labor intensity of the staff and improving the practicality of the device. By setting the protective component 6, the servo motor 66 drives the rotating shaft 67 to rotate, and the rotating shaft 67 drives the worm gear. The worm gear 68 rotates, driven by the cooperation of the worm wheel 62, causing the threaded rod 61 to rotate and drive the threaded block 63 and the protective cover 64 to rise and fall. During testing, the protective cover 64 completely covers the water tank 5 and the tire area, effectively blocking the flying fragments of the tire. This avoids injury to operators from sudden tire explosions, further improving the practicality of the device. It solves the problem that the commonly used method of tire air tightness testing involves placing the tire in a basin full of water and then manually rotating the tire to find the leak. This testing method increases the labor intensity of the workers, and the operators need to be in close contact with the high-pressure tire during testing. If the tire suddenly explodes during the testing process, the flying fragments can easily cause personal injury.
