Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile tire air tightness detection, specifically to a device for detecting automobile tire air tightness. BACKGROUND

[0002] The automobile tire is a circular ring elastic rubber product, usually installed on the metal rim. Its main function is to support the vehicle body, buffer impact, and ensure the driving performance of the vehicle. The tire moves the vehicle through the way of ground rolling, effectively filters out some bumps, and provides better ride experience for the driver. The depth of the tire pattern is an important factor affecting the tire grip and drainage performance. In order to ensure driving safety, maintain vehicle performance, improve fuel efficiency and prolong tire life, the device is used for air tightness detection of automobile tire.

[0003] The traditional device for detecting the air tightness of automobile tire, when completing the air tightness detection of one tire, needs to disassemble the detected tire and replace the tire to be detected, which increases the detection time. In order to solve the above problem, part of the device for detecting the air tightness of automobile tire, by setting two mounting discs on the connecting seat, and installing tires on the two mounting discs, and setting a translation mechanism on the detection mechanism (water tank), when the lifting structure drives the connecting seat to descend, one tire enters the detection mechanism for detection, and when the detection is completed, the detection mechanism is moved to the lower side of the other tire through the translation mechanism, and the above process is repeated, and the detected tire is replaced, so as to reduce the detection time. But this way, because the tire rotates and drives the liquid to be thrown to both sides, and the translation mechanism drives the detection mechanism to move, not only increases the disassembly difficulty, but also increases the use cost. Therefore, a device for detecting the air tightness of automobile tire is provided. Utility model content
