Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, and in particular to a gas tightness testing connector assembly that is easy to disassemble and assemble. Background Technology

[0002] Air tightness testing is a method for inspecting the air tightness of cavity mechanical products using specific methods. It is commonly used in fields such as machinery, automotive industry, medical devices, and manufacturing to ensure that there are no leaks at the connection points of the product.

[0003] Chinese patent CN219434278U discloses a quick connector for airtightness testing. The key technical features are: a connecting base with a testing port connector at its front end and an air source connector at its rear end. The air source connector has threads on its outer surface. An upper clamping claw is rotatably mounted on the upper surface of the connecting base via a large rotating shaft, and a lower clamping claw is rotatably mounted on the lower surface of the connecting base via the same shaft. The upper and lower clamping claws are symmetrically arranged. Clamping grooves are provided at the ends of both the upper and lower clamping claws away from the connecting base. Locking claw mounting seats are fixedly mounted on the middle of the two sides of the upper clamping claw, and locking claws are rotatably mounted on the locking claw mounting seats via small rotating shafts. This invention has a reasonable and effective structure and is more convenient to use.

[0004] Existing technologies often have the following drawbacks: When using quick-connect fittings for airtightness testing to perform airtightness testing on products, the different fitting sizes of different products make it difficult for quick-connect fittings to be adapted to the fixing work of different products. As a result, quick-connect fittings for airtightness testing need to be manufactured according to the fitting sizes of different products, leading to higher testing costs.

[0005] Therefore, this utility model provides a gas tightness testing connector assembly that is easy to assemble and disassemble. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where quick-connect gas tightness testing is used to perform gas tightness testing on products. Due to the different connector sizes of different products, quick-connect gas tightness testing is difficult to adapt to the fixing work of different products, thus requiring the production of quick-connect gas tightness testing according to the connector size of different products, resulting in high testing costs. Therefore, this invention proposes a gas tightness testing connector assembly that is easy to assemble and disassemble.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a gas tightness testing connector assembly that is easy to assemble and disassemble, comprising a connecting base, a gas source connector, and a testing port connector. The testing port connector is frustoconical. Upper clamping claws are rotatably connected to both sides of the connecting base, and lower clamping claws are rotatably connected to both sides of the connecting base. Two fixing blocks are fixedly connected to the sides of the two upper clamping claws that are far from each other. A clamping block is detachably installed at the end of the two upper clamping claws that is far from the connecting base. A sleeve plate is rotatably connected to the side of the two fixing blocks that are close to each other. A retaining plate is slidably connected to the inner wall of the sleeve plate. A "T" shaped groove is opened on the side of the two upper clamping claws that is far from the testing port connector. A "T" shaped block is slidably connected to the surface of the "T" shaped groove on the two upper clamping claws. The "T" shaped block is fixedly connected to the clamping block. A baffle is installed on the side of the two upper clamping claws that is close to the gas source connector. The baffle fits tightly with the upper clamping claw.

[0008] The effect achieved by the above components is that when performing airtightness testing on different products to be tested, the clamping block can be replaced with a matching "T" block. After the replacement is completed, the baffle can fix the position of the clamping block to ensure its clamping effect.

[0009] Preferably, a square rod is fixedly connected to one side of the two upper gripping claws that are close to each other, and two sliding plates are slidably connected to the surface of the square rod, both of which are fixedly connected to the baffle.

[0010] The effect achieved by the above components is that, through the square rod and the sliding plate, the baffle can be stably connected to the upper clamping claw while ensuring that it can move closer to or away from the upper clamping claw.

[0011] Preferably, the surface of the square rod is fixedly connected to two fixing plates, and the surface of the square rod is fitted with two first springs, the two ends of the two first springs being fixedly connected to the slide plate and the fixing plates respectively.

[0012] The effect achieved by the above components is that the fixing plate can install and position the first spring, thereby using the first spring to limit the position of the slide.

[0013] Preferably, a control plate is fixedly connected to the side of the baffle away from the square rod, and a limit plate is fixedly connected to the side of the two upper clamping claws near the sleeve plate.

[0014] The effects achieved by the above components are as follows: the control panel can be used to easily adjust the position of the baffle, and the limit plate can be used to limit the rotation angle of the sleeve.

[0015] Preferably, a first arc-shaped plate is fixedly connected to the side of the sleeve plate near the limiting plate, and a second arc-shaped plate is fixedly connected to the side of the clamping plate near the first arc-shaped plate. An adjusting screw is threaded into the inner wall of the second arc-shaped plate, and the adjusting screw is rotatably connected to the first arc-shaped plate.

[0016] The effect achieved by the above components is that by rotating the adjusting screw, which causes it to rotate on the surface of the first arc-shaped plate and the inner wall of the second arc-shaped plate, the position of the clamping plate can be adjusted.

[0017] Preferably, an "L"-shaped plate is fixedly connected to the side of each of the two upper clamping claws near the sleeve plate, and a limit rod is slidably connected to the inner wall of the "L"-shaped plate.

[0018] The effect achieved by the above components is that the limiting rod can be connected to the upper clamping claw through the set "L" shaped plate, thereby limiting the position of the sleeve plate by using the limiting rod.

[0019] Preferably, the end of the limiting rod away from the sleeve plate is fixedly connected to an installation plate, and a second spring is sleeved on the surface of the limiting rod. The two ends of the second spring are fixedly connected to the installation plate and the "L"-shaped plate, respectively.

[0020] The effect achieved by the above components is that the second spring can be installed through the mounting plate, thereby using the second spring to limit the position of the limiting rod, while ensuring a stable connection between the limiting rod and the "L"-shaped plate.

[0021] In summary:

[0022] 1. In this utility model, by setting the "T"-shaped block, the clamping block can be matched and replaced according to the size of the connector of the product to be tested, thereby reducing the testing cost. At the same time, by controlling the sliding of the clamping plate on the inner wall of the sleeve, the distance between the clamping plate and the upper clamping claw can be adjusted, so that when testing products of different sizes, the clamping plate can provide a good fixing effect for the upper and lower clamping claws.

[0023] 2. In this utility model, the rotation angle of the card plate can be limited by the setting of the limiting plate. At the same time, with the limiting rod, the position of the card plate can be limited when it is in use or idle, thereby avoiding the card plate shaking during the movement of the airtightness test connector assembly as much as possible.

[0029] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, this utility model provides a technical solution: a gas tightness testing connector assembly that is easy to assemble and disassemble, including a connecting seat 1, a gas source connector 2, and a testing port connector 3. The testing port connector 3 is frustoconical. Upper clamping claws 4 are rotatably connected to both sides of the connecting seat 1, and lower clamping claws 8 are rotatably connected to both sides of the connecting seat 1. Two fixing blocks 6 are fixedly connected to the sides of the two upper clamping claws 4 that are far apart from each other. A clamping block 5 is detachably installed at the end of the two upper clamping claws 4 that is far away from the connecting seat 1. A sleeve plate 17 is rotatably connected to the side of the two fixing blocks 6 that is close to each other. A retaining plate 7 is slidably connected to the inner wall of the sleeve plate 17. A "T" shaped groove is opened on the side of the two upper clamping claws 4 that is far away from the testing port connector 3. A "T" shaped block 9 is slidably connected to the surface of the "T" shaped groove on the two upper clamping claws 4. The "T" shaped block 9 is fixedly connected to the clamping block 5. A baffle 10 is installed on the side of the two upper clamping claws 4 that is close to the gas source connector 2. The baffle 10 fits tightly with the upper clamping claw 4. When performing airtightness testing on different products, the clamping block 5 can be replaced with a matching T-shaped block 9. After replacement, the baffle 10 can fix the position of the clamping block 5 to ensure its clamping effect.

[0030] The following is a detailed explanation of its overall setup and function.

[0031] Reference Figures 1-4As shown in this embodiment: a square rod 13 is fixedly connected to one side of the two upper gripping claws 4 that are close to each other. Two sliding plates 12 are slidably connected to the surface of the square rod 13, and both sliding plates 12 are fixedly connected to the baffle 10. Through the square rod 13 and sliding plates 12, the baffle 10 can be stably connected to the upper gripping claws 4 while allowing it to move closer to or away from the upper gripping claws 4. Two fixing plates 14 are fixedly connected to the surface of the square rod 13, and two first springs 15 are sleeved on the surface of the square rod 13. The two ends of the two first springs 15 are fixedly connected to the sliding plates 12 and the fixing plates 14, respectively. The fixing plates 14 can install and position the first springs 15, thereby using the first springs 15 to restrict the position of the sliding plates 12. A control plate 11 is fixedly connected to the side of the baffle 10 away from the square rod 13, and limit plates 16 are fixedly connected to the side of the two upper gripping claws 4 that are close to the sleeve plate 17. The control panel 11 allows for easy adjustment of the position of the baffle 10, while the limit plate 16 limits the rotation angle of the sleeve 17.

[0032] A first arc-shaped plate 18 is fixedly connected to the side of the sleeve 17 near the limiting plate 16, and a second arc-shaped plate 19 is fixedly connected to the side of the clamping plate 7 near the first arc-shaped plate 18. An adjusting screw 20 is threaded into the inner wall of the second arc-shaped plate 19, and the adjusting screw 20 is rotatably connected to the first arc-shaped plate 18. By rotating the adjusting screw 20, it can rotate on the surface of the first arc-shaped plate 18 and the inner wall of the second arc-shaped plate 19, thereby adjusting the position of the clamping plate 7. An "L"-shaped plate 21 is fixedly connected to the side of each of the two upper clamping claws 4 near the sleeve 17, and a limiting rod 22 is slidably connected to the inner wall of the "L"-shaped plate 21. The limiting rod 22 can be connected to the upper clamping claw 4 through the "L"-shaped plate 21, thereby limiting the position of the sleeve 17. A mounting plate 23 is fixedly connected to the end of the limiting rod 22 away from the sleeve plate 17. A second spring 24 is fitted onto the surface of the limiting rod 22, and both ends of the second spring 24 are fixedly connected to the mounting plate 23 and the "L"-shaped plate 21, respectively. The second spring 24 can be installed through the mounting plate 23, thereby using the second spring 24 to limit the position of the limiting rod 22, while ensuring a stable connection between the limiting rod 22 and the "L"-shaped plate 21.

[0033] Working principle: When the gas tightness test connector assembly is needed to test the product to be tested, firstly, select the matching clamping block 5 according to the size of the connector of the product to be tested. Then, move the control plate 11 to drive the baffle 10 to move, so that the two slide plates 12 slide on the surface of the square rod 13, so that the two move closer to each other. Then, install the clamping block 5 onto the upper clamping jaw 4 through the "T" block 9. Release the control plate 11. Under the action of the first spring 15, the slide plate 12 moves closer to the fixed plate 14. At this time, the baffle 10 restricts the position of the "T" block 9. Then, connect the gas source connector 2 on the connecting seat 1 to the gas source pipe, and then connect the connector of the product to be tested to the test port connector 3. Rotate the upper clamping jaw 4 and the lower clamping jaw 8 to each other. Approaching each other, pull the mounting plate 23. At this time, the limiting rod 22 slides on the inner wall of the "L"-shaped plate 21, causing the limiting rod 22 to move away from the sleeve plate 17, releasing the restriction on the position of the clamping plate 7. Rotate the sleeve plate 17 and the clamping plate 7. At this time, the sleeve plate 17 rotates on the surface of the fixing block 6, causing the clamping plate 7 to move away from the limiting plate 16. Rotate the adjusting screw 20 to rotate on the inner wall of the second arc plate 19 and the surface of the first arc plate 18, adjusting the position of the clamping plate 7 until the clamping plate 7 can fix the upper clamping claw 4 and the lower clamping claw 8. Release the mounting plate 23. At this time, under the action of the elastic force of the second spring 24, the limiting rod 22 moves closer to the sleeve plate 17, restricting the rotation of the sleeve plate 17 and the clamping plate 7. Then the air tightness test of the product to be tested can begin. By using the "T"-shaped block 9, the clamping block 5 can be replaced to match the size of the connector of the product to be tested, thereby reducing the testing cost. At the same time, by controlling the sliding of the clamping plate 7 on the inner wall of the sleeve plate 17, the distance between the clamping plate 7 and the upper clamping claw 4 can be adjusted, so that when testing products of different sizes, the clamping plate 7 can provide a good fixing effect for the upper clamping claw 4 and the lower clamping claw 8. The limiting plate 16 can limit the rotation angle of the clamping plate 7, and together with the limiting rod 22, the position of the clamping plate 7 can be limited when it is in use or idle, thereby minimizing the shaking of the clamping plate 7 during the movement of the airtightness testing connector assembly.
