[0023] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] like Figures 1 to 4 As shown, an oxygen production and storage device includes a base 1, a fixed structure 3, an oxygen storage tank 4, a protective structure 5, a shock absorbing device 6 and a movable wheel 7. A placement groove 2 is opened on the top of the base 1, and the oxygen storage tank is placed in the placement groove. The fixed structure 3 is arranged on the base 1, and the oxygen storage tank 4 is clamped and fixed by the fixed structure 3 to increase the stability of the oxygen storage tank 4 in the base 1. The protective structure 5 is arranged around the outside of the oxygen storage tank 4. By installing the protective structure 5 on the outside of the oxygen storage tank 4, it is protected to avoid damage to the oxygen storage tank 4 caused by external impact. The shock absorbing device 6 is provided at the four corners of the bottom of the base 1, and the movable wheel 7 is provided at the bottom of the shock absorbing device 6. The movable wheel 7 and the shock absorbing device 6 are used in conjunction with each other to facilitate the movement of the oxygen storage tank 4 while also having a shock absorbing effect to avoid instability inside the oxygen storage tank 4 caused by bumps;

[0025] The fixing structure 3 includes a movable plate 301, which is arranged on both sides of the placement groove 2. The two movable plates 301 are rotatably connected to the side away from each other with a threaded rod 302. The end of the threaded rod 302 away from the movable plate 301 is inserted into the groove wall of the placement groove 2 and is connected to the groove wall thread structure. A positioning seat 303 is fixedly connected to the middle position of the placement groove 2. After the oxygen storage tank 4 is placed on the top of the positioning seat, the threaded rod 301 is rotated to push the movable plate 302 to contact the surfaces on both sides of the oxygen storage tank 4, thereby clamping the oxygen storage tank 4 to prevent the oxygen storage tank 4 from being unstable during movement.

[0026] The protective structure 5 includes a protective plate 501. There are several protective plates 501, which are evenly distributed around the outside of the oxygen storage tank 4. Buffer rods 502 are provided at both ends of the protective plate 501 close to the oxygen storage tank 4. The end of the buffer rod 502 away from the protective plate 501 is fixedly connected to the surface of the oxygen storage tank 4. The buffer rod 502 includes a fixed cylinder 5021, which is fixedly connected to the outside of the oxygen storage tank 4. A movable rod 5022 is inserted into the fixed cylinder 5021. The end of the movable rod 5022 away from the fixed cylinder 5021 is fixedly connected to the protective plate. 501, a buffer spring 5023 is fixedly connected between the movable rod 5022 and the interior of the fixed cylinder 5021. A corresponding damping device is provided inside the buffer spring 5023. When the protective plate 501 and the buffer rod 502 are used in conjunction with each other, the protective plate 501 can squeeze the buffer rod 502 when the outside of the oxygen storage tank 4 is hit. At the same time, the movable rod 5022 in the buffer rod 502 squeezes the buffer spring 5023. When used in conjunction with the damping device, the external force is buffered and weakened, greatly reducing damage to the oxygen storage tank 4.
