In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0026] like Figure 1-5 As shown, the utility model provides a molecular sieve cartridge quick installation structure, which is used in conjunction with a molecular sieve cartridge 10. The molecular sieve cartridge 10 includes a mounting seat 11 and a cylinder 12. The top of the mounting seat 11 has a retaining edge 13, and the mounting seat 11 has a locking groove 14. The above contents are all public prior art, and the specific structure is not repeated here. The utility model includes a housing 20, a locking assembly 30 and a driving assembly 40.

[0027] The housing 20 is fixedly mounted on an instrument or device that needs to use the molecular sieve cartridge 10 , such as an oxygen concentrator, a purifier, etc. A through hole 21 adapted to the mounting seat 11 is formed on the housing 20 , and the retaining edge 13 cannot pass through the through hole 21 .

[0028] The locking assembly 30 includes a guide rail 31, a slider 32 and a locking block 33. The guide rail 31 is fixedly mounted on the housing 20 in the transverse direction. The slider 32 is disposed on the guide rail 31 and is slidably connected to the guide rail 31. Preferably, the guide rail 31 is a T-shaped guide rail 31. The locking block 33 is fixedly mounted on the slider 32 and is adapted to the locking groove 14.

[0029] The driving assembly 40 is used to control the slider 32 to move on the guide rail 31 .

[0030] The specific replacement process of the molecular sieve cartridge 10 is as follows: first, the user controls the slider 32 to move on the guide rail 31 through the control component, so that the slider 32 is away from the molecular sieve cartridge 10, until the locking block 33 is disengaged from the locking groove 14, and the user pulls up the mounting seat 11 to remove the old molecular sieve cartridge 10. Then, the barrel 12 of the new molecular sieve cartridge 10 is inserted into the through hole 21, and then the slider 32 is controlled by the control component to move on the guide rail 31, so that the slider 32 is close to the molecular sieve cartridge 10, until the locking block 33 is inserted into the locking groove 14, so that the new molecular sieve cartridge 10 can be quickly installed.

[0031] The molecular sieve cartridge 10 of the utility model has a simple installation process, convenient operation and high installation efficiency.

[0032] In one embodiment, a switch slot 22 is formed on one side of the housing 20 away from the through hole 21 and extending through the housing 20 in a transverse direction.

[0033] The driving assembly 40 includes a transmission rod 41, a first connecting shaft 42, a fixed plate 43, a second connecting shaft 44, a torsion spring 45 and a movable plate 46. The transmission rod 41 is arranged on the housing 20 in the transverse direction, and the middle part of the transmission rod 41 is rotatably connected to the housing 20 via a rotating shaft 47. The first end of the transmission rod 41 is provided with a first guide groove 48 extending along its length direction and penetrating in the longitudinal direction. The first connecting shaft 42 is connected to the second end of the transmission rod 41. The fixed plate 43 is fixedly mounted on the slider 32 in the transverse direction. The second connecting shaft 44 is arranged in the first guide groove 48 and adapted to the first guide groove 48. The second connecting shaft 44 is in sliding contact with the inner wall of the first guide groove 48, and the second connecting shaft 44 is connected to the fixed plate 43. The torsion spring 45 makes the first end of the transmission rod 41 have a tendency to approach the slider 32. The movable plate 46 is laterally arranged in the switch slot 22 and adapted to the switch slot 22 . A second guide slot 49 extending along its length direction and penetrating along the longitudinal direction is opened on the movable plate 46 . The inner wall of the second guide slot 49 is adapted to the first connecting shaft 42 , and the inner wall of the second guide slot 49 is in sliding contact with the first connecting shaft 42 .

[0034] In the initial state, due to the action of the torsion spring 45, the first end of the transmission rod 41 applies a force to the slider 32, so that the locking block 33 is inserted into the locking groove 14, thereby keeping the molecular sieve cartridge 10 stable and enabling stable adsorption operation.

[0035] The specific working process of the driving component 40 is as follows:

[0036] The user pulls the movable plate 46 horizontally, and under the action of the second guide groove 49 and the first connecting shaft 42, the rotating plate will rotate, and then under the action of the first guide groove 48 and the second connecting shaft 44, the fixed plate 43 will pull the slider 32 until the locking block 33 is disengaged from the locking groove 14, and the user can pull the mounting seat 11 upwards to remove the old molecular sieve cartridge 10.

[0037] After the user inserts the cylinder body 12 of the new molecular sieve cylinder 10 into the through hole 21, the movable plate 46 is loosened, and the rotating rod is reset under the action of the torsion spring 45, and the locking block 33 is inserted into the locking groove 14 on the new molecular sieve cylinder 10, and the utility model returns to the initial state.

[0038] The driving assembly 40 has a simple structure and is easy to produce and manufacture. When in use, the user only needs to pull the movable plate 46 to remove the old molecular sieve cartridge 10 and install the new molecular sieve cartridge 10, which is convenient to operate.

[0039] In one embodiment, the torsion spring 45 is sleeved on the rotating shaft 47. This design can prevent the torsion spring 45 from bending, making the operation of the utility model more stable.

[0040] In one embodiment, the second end of the movable plate 46 extends outward from the housing 20 to facilitate the user to pull the movable plate 46 .

[0041] In one embodiment, the first connecting shaft 42 is rotatably connected to the second end of the transmission rod 41 , and the second connecting shaft 44 is rotatably connected to the fixing plate 43 .

[0042] In this way, when the transmission rod 41 rotates, the first connecting shaft 42 will rotate in the second guide groove 49, thereby reducing the friction between the first connecting shaft 42 and the inner wall of the second guide groove 49. The second connecting shaft 44 will rotate in the first guide groove 48, thereby reducing the friction between the second connecting shaft 44 and the inner wall of the first guide groove 48. This makes the stability of the utility model better.

[0043] In one embodiment, there are two guide rails 31 , and the two guide rails 31 are respectively located on two sides of the slider 32 .

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
