Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, specifically to a quick-release sealing structure for an oxygen generator adsorption tower. Background Technology

[0002] The adsorption tower of an oxygen generator is the core component of the oxygen generator, mainly used to separate oxygen from the air. An end cap is connected to the top of the adsorption tower. During the oxygen production process, the end cap needs to be in close contact with the tower body to ensure airtightness. After the end cap is removed, the inside of the tower body can be inspected and maintained, such as replacing the molecular sieve or cleaning the interior.

[0003] In existing technologies, a sealing ring is usually installed between the tower body and the end cap. After aligning the end cap with the tower body, a clamp is used to quickly fix or loosen the tower body and the end cap. However, in actual use, with prolonged use of the clamp, the clamp is prone to deformation, which can cause the end cap to shift and leak. This has certain limitations. Therefore, it is necessary to improve the quick-release sealing structure of the oxygen generator adsorption tower to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release sealing structure for an oxygen generator adsorption tower to solve the problems mentioned in the background art.

This facilitates the adjustment of the position of the connecting seat according to the position of the tower body, making the opening and closing of the sealing cover more convenient.

[0007] Preferably, the connector has a threaded hole at the position corresponding to the bolt, and the bolt is threaded into the threaded hole to facilitate the limiting operation of the connector.

[0008] Preferably, the limiting mechanism includes a connecting block, which is slidably installed inside the positioning groove. The second L-shaped block is slidably installed on the inner wall of the connecting block. A threaded post is threaded inside the connecting block. A sliding plate is rotatably installed at one end of the threaded post. The sliding plate is slidably installed on the inner wall of the connecting block.

[0011] Compared with the prior art, this utility model provides a quick-release sealing structure for an oxygen generator adsorption tower, which has the following advantages:

[0012] 1. The quick-release sealing structure of this oxygen generator adsorption tower, through the positioning mechanism, facilitates the wrapping of the tower body during use via the connecting ring, preventing deformation of the tower body under high pressure and ensuring the tower body's sealing performance. The positioning groove allows for easy adjustment of the connecting seat position according to the tower body's placement, making the opening and closing of the sealing cover more convenient. With the cooperation of bolts, the connecting seat is easy to disassemble and assemble. The rotating shaft and the first L-shaped block facilitate the rotation of the sealing cover, ensuring contact between the sealing gasket and the tower body and preventing the sealing cover from shifting.

[0013] 2. The quick-release sealing structure of the oxygen generator adsorption tower, through the setting of the limiting mechanism, allows for easy adjustment of the orientation of the connecting block according to the position of the connecting seat during use via the detachable connecting block. By rotating the threaded column, with the cooperation of the guide column, the sliding plate can be moved, thereby facilitating the contact between the extrusion block and the rotating wheel, facilitating the downward movement of the extrusion rotating wheel, and facilitating the downward movement of the second L-shaped block and the sealing cover, so that the sealing gasket fits tightly with the tower body, and facilitating the quick limiting of the sealing cover.

[0023] Example 1:

[0024] Please see Figure 1-3 This utility model provides a technical solution: a quick-release sealing structure for an oxygen generator adsorption tower, including a tower body 1 and a sealing cover 2. A sealing gasket 3 is provided at the bottom of the sealing cover 2. A positioning mechanism 4 is provided on the outside of the tower body 1. A limit mechanism 5 is provided inside the positioning mechanism 4.

[0025] Furthermore, the positioning mechanism 4 includes a connecting ring 401, which is fixedly installed on the outside of the tower body 1. A positioning groove 402 is provided inside the connecting ring 401, and a connecting seat 403 is slidably installed inside the positioning groove 402. A bolt 404 is threaded inside the connecting ring 401, and a rotating shaft 405 is rotatably installed inside the connecting seat 403. A first L-shaped block 406 is fixedly installed on the outside of the rotating shaft 405. The first L-shaped block 406 is fixedly installed with the sealing cover 2, and a second L-shaped block 407 is fixedly installed on the outside of the sealing cover 2. This facilitates the adjustment of the position of the connecting seat 403 according to the position of the tower body 1, making the opening and closing of the sealing cover 2 more convenient.

[0026] Furthermore, the interior of the connecting seat 403 is provided with a threaded hole at the position corresponding to the bolt 404, and the bolt 404 is threadedly installed in the threaded hole, which facilitates the limiting operation of the connecting seat 403.

[0027] Example 2:

[0028] Please see Figure 4-5 Furthermore, in conjunction with Embodiment 1, the limiting mechanism 5 includes a connecting block 501, which is slidably installed inside the positioning groove 402. A second L-shaped block 407 is slidably installed on the inner wall of the connecting block 501. A threaded post 502 is threadedly installed inside the connecting block 501. A sliding plate 503 is rotatably installed at one end of the threaded post 502. The sliding plate 503 is slidably installed on the inner wall of the connecting block 501. A pressing block 504 is fixedly installed at one end of the sliding plate 503. The pressing block 504 and the second L-shaped block... The 407 sliding installation is particularly noteworthy because the extrusion block 504 has an inclined surface, which contacts the rotating wheel 506, facilitating the extrusion of the rotating wheel 506 and the downward movement of the rotating wheel 506 and the second L-shaped block 407, thus facilitating the limiting operation of the sealing cover 2. A guide post 505 is fixedly installed at the end of the sliding plate 503 away from the extrusion block 504. The rotating wheel 506 is rotatably installed inside the second L-shaped block 407, and the extrusion block 504 contacts the rotating wheel 506, facilitating the rapid limiting operation of the sealing cover 2.

[0029] Furthermore, the connecting block 501 has a threaded hole at the position corresponding to the bolt 404, and the bolt 404 is threadedly installed in the threaded hole, which facilitates the limiting operation of the connecting block 501.

[0030] Furthermore, a through hole is provided inside the connecting block 501 at the position corresponding to the guide post 505, and the guide post 505 is slidably installed in the through hole to facilitate the smooth movement of the slide plate 503.

[0031] In actual operation, when this device is used, the connecting seat 403 is inserted into the appropriate positioning groove 402 according to the placement position of the tower body 1. With the cooperation of the bolt 404, the connecting seat 403 is limited, completing the positioning of the sealing cover 2. The operation is repeated to position and limit the connecting block 501. When sealing the tower body 1, the sealing cover 2 is rotated, causing the rotating shaft 405 and the first L-shaped block 406 to rotate, so that the second L-shaped block 407 slides on the inner wall of the connecting block 501, so that the sealing gasket 3 contacts the tower body 1. By rotating the threaded column 502, the sliding plate 503 moves towards the second L-shaped block 407, so that the inclined surface of the extrusion block 504 contacts the rotating wheel 506. As the extrusion block 504 continues to move, it extrudes the rotating wheel 506, so that the rotating wheel 506 and the second L-shaped block 407 move downward, so that the sealing gasket 3 contacts the tower body 1 tightly, completing the limiting of the sealing cover 2.
