However, it should be noted that the specific embodiments described are not intended to limit the specific implementation of the present invention. All similar structures and variations thereof employing the present invention should be included within the protection scope of the present invention. The following description of the embodiments refers to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented. Directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of the present invention, and not for limiting the present invention.

[0023] See Figure 1 A testing fixture for testing sealing rings includes a first cover plate 1, a second cover plate 2, and a partition plate 3; the first cover plate 1 and the second cover plate 2 are detachably connected, and an O-ring is provided between the first cover plate 1 and the second cover plate 2; the first cover plate 1 and the partition plate 3 are detachably connected, and a limiting pad 4 is provided between the first cover plate 1 and the partition plate 3; an air inlet 6 is provided on the first cover plate 1, and an air collection port 7 is provided on the second cover plate 2.

[0024] The first cover plate 1 and the second cover plate 2 are bolted together, and the first cover plate 1 and the partition plate 3 are bolted together. The first cover plate 1 is flat, the second cover plate 2 is concave, and the partition plate 3 is flat. The length of the partition plate 3 is less than the width of the concave surface of the second cover plate 2.

[0025] The O-ring is positioned on the side closest to the partition 3. Specifically, as shown in the figure, the O-ring is positioned on the left and right protrusions of the second cover plate 2, closer to the center. The limiting pad 4 is a cuboid block, which serves to limit and position the air. The limiting pad 4 is positioned away from the air inlet 6. Specifically, as shown in the figure, the limiting pad 4 is used to block the position of the test seal 5, ensuring that the air inlet 6 is located in the center of the test seal 5.

[0026] The air inlet 6 is circular and equipped with a G5 / 8 national standard adapter thread for easy installation of air hoses, thus enabling easy switching between various gases. The air collection port 7 is also circular and equipped with a G5 / 8 national standard adapter thread for easy installation of air hoses, again enabling easy switching between various gases. Gas can enter from the outside through the air inlet 6 of the first cover plate 1. If the test seal 5 has an airtightness problem, gas will escape from the air collection port 7.

[0027] The first cover plate 1 and the second cover plate 2 are connected by bolts, as are the first cover plate 1 and the partition plate 3. Various bolt specifications can be selected for connection according to the size of the seal. The bolts are located on the outside of the seal and will not affect the test results.

[0028] The first cover plate 1 and the second cover plate 2 are sealed with an O-ring to ensure that the entire tooling is sealed and to prevent internal gas leakage, which could lead to inaccurate test results.

[0029] The thickness of the limiting pad 4 can be freely adjusted according to the test requirements. Its shape is a small rectangular block, which is convenient to replace. By placing the limiting pad 4 and the test seal 5 at a suitable position on the first cover plate 1, placing the partition plate 3 and tightening it with appropriate bolts, the distance between the partition plate 3 and the first cover plate 1 is equal to the thickness of the limiting pad 4. It can be measured with measuring tools such as calipers.

[0030] In practice,

[0031] Place the limiting pad 4 and the test seal 5 in the appropriate position on the first cover plate 1, then place the partition 3 on top and tighten it with appropriate bolts so that the distance between the partition 3 and the first cover plate 1 is equal to the thickness of the limiting pad 4. The distance can be accurately measured with measuring tools such as calipers to ensure that it meets the test requirements.

[0032] After correctly installing the O-ring on the bottom plate, place the assembled first cover plate 1 on the bottom plate, and then tighten the first cover plate 1 and the second cover plate 2 with appropriate bolts to ensure that there is no gap between them and to ensure the sealing of the entire fixture.

[0033] After assembly, connect the gas cylinder to the air inlet 6 of the tooling via a G5 / 8 thread, and connect the air outlet to the collection device (e.g., in water) via a gas pipe.

[0034] Open the gas cylinder valve and adjust it to the required test pressure position. At this time, the gas will reach the test seal 5 position through the gap inside the tooling. If there is a gas leak, the gas will reach the gas collection port 7 through the gap, accompanied by bubbles. The gas sealing performance of the seal can be judged based on the bubble situation.
