The front right side of the connecting pipe 10 is connected to the movable hook plate 17. The movable hook plate 17 will contact the first vertical contact portion 15 of the first contact block 14 during the process of moving to the left. The lower part of the movable hook plate 17 is connected to the push block 18. The push block 18 and the first contact block 14 The second valve 9 is connected to a second contact block 19, and the second contact block 19 is provided with a second vertical contact portion 20 and a second horizontal contact portion 21. A fixed hook plate 22 is connected to the upper left side of the large oxygen tank 1. When the second contact block 19 moves to the left, the second vertical contact portion 20 of the second contact block 19 will contact the fixed hook plate 22.

[0031] like Fig. 9 and Fig.10 As shown, the fixing mechanism includes a ring 25, a connecting block 26, a clamping block 27 and a spring 28. The right part of the connecting pipe 10 is connected to the ring 25, the top of the air outlet pipe 2 is connected to the connecting block 26, the left part of the connecting block 26 is slidably connected to the clamping block 27, the left side of the clamping block 27 is provided with an inclined surface 271, and two springs 28 are connected between the clamping block 27 and the connecting block 26.
[0032] like Figure 1 As shown, it also includes a mounting plate 29 and a shoulder strap 30. The front side of the small oxygen tank 7 is connected to the mounting plate 29, and the left and right sides of the front side of the mounting plate 29 are connected to the shoulder strap 30.
[0033] like Figure 1 As shown, a handle 38 is also included, and the front and rear sides of the right side of the mounting frame 4 are connected with the handle 38.
[0034] Initially, the first valve 3 and the third valve 11 are in the open state, and the second valve 9 is in the closed state. The medical staff connects the oxygen tube 13 to the mask, and the oxygen in the large oxygen tank 1 enters the humidifier 12 through the outlet pipe 2 and the connecting pipe 10. The humidifier 12 humidifies the oxygen, and then the oxygen enters the patient's body through the oxygen tube 13 for oxygen supply. The block 27 can clamp the ring 25 and fix the connecting pipe 10 on the outlet pipe 2 to prevent the connecting pipe 10 from falling off the outlet pipe 2. When the patient needs to go out for activities, the medical staff pulls the block 27 upward so that the block 27 no longer clamps the ring 25, the spring 28 stretches, and then pulls the small oxygen tank 7 to the left, and the small oxygen tank 7 drives the airway pipe 8 and the connecting pipe 10 to move to the left, so that the connecting pipe 10 and the outlet pipe 2 Disengagement, the connecting pipe 10 moves to the left and can also drive the movable hook plate 17 and the pushing block 18 to move to the left. The pushing block 18 moves to the left and gradually disengages from the first horizontal contact portion 16 of the first contact block 14. At this time, the movable hook plate 17 does not contact the first vertical direct contact portion 15 of the first contact block 14. After the pushing block 18 and the first horizontal contact portion 16 of the first contact block 14 are completely disengaged, the movable hook plate 17 will contact the first vertical direct contact portion 15 of the first contact block 14. The movable hook plate 17 pulls the first vertical direct contact portion 15 of the first contact block 14 to rotate the first contact block 14. The first contact block 14 drives the first valve 3 to rotate and close the first valve 3. At the same time, the air guide pipe 8 moves to the left, which will drive the second valve 9 to 23, the second contact block 19 is in contact with the second vertical contact portion 20, and the second contact block 19 is in contact with the fixed hook plate 22. After the second horizontal contact portion 21 of the second contact block 19 is completely out of contact with the fixed block 23, the second vertical contact portion 20 of the second contact block 19 will be in contact with the fixed hook plate 22. Under the action of the fixed hook plate 22, the second contact block 19 will rotate, and the second contact block 19 will drive the second valve 9 to rotate to open the second valve 9. The second valve 9 rotates and drives the third valve 11 to rotate through the connecting rod 24 to close the third valve 11. At this time, the oxygen in the large oxygen tank 1 is no longer discharged, and the small oxygen tank 1 is closed. The oxygen in the gas tank 7 enters the connecting pipe 10 through the airway pipe 8 to continue oxygen supply. The small oxygen tank 7 can be removed from the mounting frame 4 to facilitate the patient's activities. The patient can carry the small oxygen tank 7 through the shoulder strap 30 to facilitate carrying the small oxygen tank 7. After the patient returns to the ward, the small oxygen tank 7 is put back on the mounting frame 4. The small oxygen tank 7 drives the airway pipe 8 and the connecting pipe 10 to move to the right, so that the connecting pipe 10 and the air outlet pipe 2 are connected. The rightward movement of the connecting pipe 10 can also drive the second valve 9, the ring 25, the movable hook plate 17, the pushing block 18 and the second contact block 19 to move to the right. The pushing block 18 will contact the first horizontal contact portion 16 of the first contact block 14, so that the pushing block 18 can push the first contact block 14 to rotate the first contact block 14.The first contact block 14 drives the first valve 3 to rotate and open the first valve 3. The second horizontal contact portion 21 of the second contact block 19 will contact the fixed block 23. Under the action of the fixed block 23, the second contact block 19 will rotate. The second contact block 19 drives the second valve 9 to rotate and close the second valve 9. The second valve 9 rotates and drives the third valve 11 to rotate through the connecting rod 24 to open the third valve 11. When the ring 25 moves to the right and contacts the inclined surface 271 on the block 27, the ring 25 pushes the block 27 to move upward, and the spring 28 stretches. When the ring 25 and the block 27 are out of contact, the block 27 moves downward under the action of the spring 28. The block 27 clamps the ring 25 and fixes the connecting pipe 10 on the outlet pipe 2.
[0035] Embodiment 2: Based on embodiment 1, Figure 1 As shown, it also includes a connecting frame 31 and universal wheels 32. The lower part of the large oxygen tank 1 is connected to the connecting frame 31, and four universal wheels 32 are evenly spaced and installed at the bottom of the connecting frame 31.
[0036] like Fig.11 and Fig.12 As shown, it also includes a sliding ring 33, a mounting rod 34, a suction cup 35, a magnetic block 36 and an iron plate 37. The sliding ring 33 is slidably connected to the lower part of the connecting frame 31. Four mounting rods 34 are connected to the bottom of the sliding ring 33 at evenly spaced intervals. The lower ends of the mounting rods 34 are connected to suction cups 35. Four magnetic blocks 36 are connected to the top of the sliding ring 33 at evenly spaced intervals. The left and right sides of the lower part of the connecting frame 31 are symmetrically connected to the iron plates 37, and the magnetic blocks 36 are adsorbed on the iron plates 37.
[0037] Initially, the magnetic block 36 is adsorbed on the iron plate 37, so that the suction cup 35 cannot move downward. The medical staff holds the handle 38 to push the large oxygen tank 1 to move the large oxygen tank 1 into the ward. Under the action of the universal wheel 32, the large oxygen tank 1 can be moved in any direction, which is convenient for moving the large oxygen tank 1 into the ward. After the large oxygen tank 1 is moved into the ward, the sliding ring 33 is pushed downward to disengage the magnetic block 36 and the iron plate 37. The suction cup 35 moves downward under the action of its own gravity, and the suction cup 35 comes into contact with the ground, adsorbing the suction cup 35 on the ground, thereby fixing the large oxygen tank 1 to prevent the large oxygen tank 1 from moving at will.
[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
