Description

Technical Field

[0001] The utility model belongs to the technical field of leakage detection of inflatable sealing rings, in particular to a leakage detection device for an inflatable sealing ring. Background Art

[0002] The inflatable sealing ring, also known as the air bag, is hollow inside and has one or more inflation and deflation nozzles. The inflatable sealing ring needs to be tested to verify whether the product is qualified and to demonstrate the performance and life of the inflatable sealing ring. The inflatable sealing ring is a rubber product used for sealing, usually used in hydraulic systems, pneumatic systems, valves, pumps and other equipment. Its main function is to achieve a sealing effect through inflation to prevent leakage of liquid or gas.

[0003] The traditional detection method is to manually check whether the product is qualified and record the data. However, manual detection alone cannot achieve tens of thousands of inflation and deflation experiments. It has the disadvantages of low efficiency, high cost and low detection accuracy. Therefore, we proposed an inflatable sealing ring leak detection device. Utility Model Content

[0004] The utility model aims to provide an inflatable sealing ring leak detection device, which compresses the spring downwards while the lower pressure ring slides downwards on the inner wall of the auxiliary rod, and the extension tube moves downwards with the extension rod, thereby cooperating with the rotating rod to lift the clamping plate, and then the inflatable sealing ring is placed at the bottom of the three clamping plates. Subsequently, the staff releases the lower pressure ring, and at the same time, according to the elastic force of the spring, the lower pressure ring moves upwards on the top of the auxiliary rod, thereby driving the extension rod to move upward, so that the clamping plate is squeezed downwards, completing the function of clamping and limiting the inflatable sealing ring, and avoiding the inflatable sealing ring moving position during inflation during the detection process, thereby affecting the test, thereby ensuring the stability of the detection data, and solving the problem of the existing traditional detection method of manually detecting whether the product is qualified and recording the data, but manual detection alone cannot achieve tens of thousands of inflation and deflation experiments, and there are the disadvantages of low efficiency, high cost and low detection accuracy.
