Description

Technical Field

[0001] This utility model relates to the field of pressure stabilization technology, and in particular to an oxygen pressure stabilization device. Background Technology

[0002] An oxygen pressure buffer tank is a common oxygen pressure stabilizing device, primarily used to balance pressure fluctuations during oxygen supply and ensure stable pressure at the user end. Its working principle involves regulating the instantaneous oxygen flow through an internal storage space. When the supply pressure increases, it stores excess oxygen; when the pressure decreases, it releases the stored oxygen, thereby maintaining a constant output pressure. It is widely used in medical, industrial, and other fields to ensure the safety and stability of oxygen supply.

[0003] Currently, when oxygen pressure buffer tanks need to be moved or relocated, they rely entirely on manual operation, which is time-consuming and labor-intensive. Furthermore, their structure lacks anti-tipping design, making them susceptible to tipping during movement due to bumps, collisions, and other factors, posing risks such as damage to the buffer tank itself or oxygen leakage. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide an oxygen pressure stabilizing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An oxygen pressure stabilizing device includes a buffer tank body. Four annularly distributed support legs are vertically fixedly connected to the lower end of the buffer tank body. Universal wheels are rotatably connected to the lower ends of the support legs. A support ring is fixedly fitted onto the outer wall of the buffer tank body near the bottom. Multiple grooves are annularly distributed on the outer wall of the support ring. A longitudinally arranged connecting post is provided within each groove. A longitudinally arranged connecting rod is rotatably connected within each connecting post. The front and rear ends of the connecting rod pass through the connecting post and are fixedly connected to the inner wall of the groove. A horizontally arranged support plate is provided above the connecting post. One end of the support plate is fixedly connected to the inner wall of the groove, and an insert is placed at the upper end of the support plate. There is a second locking screw, which is threadedly connected to the support plate. The lower end of the second locking screw passes through the support plate. Multiple second slots corresponding to the second locking screw are evenly distributed on the outer side wall of the connecting column. A first support rod is fixedly connected to the lower side wall of the connecting column. A second support rod is slidably inserted into the lower end of the first support rod. A first locking screw is inserted into the outer side wall of the first support rod near the bottom. The first locking screw is threadedly connected to the first support rod. Multiple first slots corresponding to the first locking screw are provided on the outer side wall of the second support rod. One end of the first locking screw passes through the first support rod and extends into the first slot.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 An oxygen pressure stabilizing device includes a buffer tank body 1. Four annularly distributed support legs 2 are vertically fixedly connected to the lower end of the buffer tank body 1 for supporting the buffer tank body 1. A first fixing block 4 is fixedly connected to the outer wall of each support leg 2 for securing the support leg 2. The upper end of the first fixing block 4 is fixedly connected to the lower end of the buffer tank body 1. A caster wheel 3 is rotatably connected to the lower end of each support leg 2 for facilitating movement of the buffer tank body 1. A fixing ring 6 is fixedly sleeved on the outer wall of the buffer tank body 1 for securing a support ring 5. The upper end of the fixing ring 6 is fixedly connected to the lower end of the support ring 5. A support ring 5 is fixedly sleeved on the outer wall of the buffer tank body 1 near the bottom for cooperating with a first support rod 7 to support the buffer tank body 1. The outer walls of the support ring 5, the first support rod 7, and the second support rod 8 are all coated with anti-rust paint for a certain degree of rust prevention.

[0022] In this embodiment, multiple grooves are arranged in a ring on the outer sidewall of the support ring 5. A second fixing block 17 is fixedly connected to the inner sidewall of the groove for supporting the support plate 14. The upper end of the second fixing block 17 is fixedly connected to the lower end of the support plate 14. A longitudinally arranged connecting post 12 is provided in the groove for supporting the first support rod 7. A longitudinally arranged connecting rod 13 is rotatably connected in the connecting post 12 for supporting the connecting post 12. The front and rear ends of the connecting rod 13 pass through the connecting post 12 and are fixedly connected to the inner sidewall of the groove. A horizontally arranged support plate 14 is provided above 2 to support the second locking screw 15. One end of the support plate 14 is fixedly connected to the inner side wall of the groove. The second locking screw 15 is inserted into the upper end of the support plate 14 to cooperate with the second slot to lock the connecting post 12. The second locking screw 15 and the support plate 14 are threadedly connected. The lower end of the second locking screw 15 passes through the support plate 14. Multiple second slots 16 corresponding to the second locking screw 15 are evenly distributed on the outer side wall of the connecting post 12 for inserting the second locking screw 15.

[0023] In this embodiment, a first support rod 7 is fixedly connected to the lower side wall of the connecting column 12 to provide lateral support for the buffer tank body 1. A second support rod 8 is slidably inserted into the lower end of the first support rod 7 to provide lateral support for the buffer tank body 1. A second universal wheel 9 is rotatably connected to the lower end of the second support rod 8 to facilitate the movement of the buffer tank body 1. A first locking screw 10 is inserted into the outer side wall of the first support rod 7 near the bottom to cooperate with the first slot to prevent the second support rod 8 from loosening. The first locking screw 10 and the first support rod 7 are connected by threads. The outer side wall of the second support rod 8 is provided with a plurality of first slots 11 corresponding to the first locking screw 10 for inserting the first locking screw 10. One end of the first locking screw 10 passes through the first support rod 7 and extends into the first slot 11.

[0024] In this embodiment, firstly, the first universal wheel 3 facilitates the convenient displacement of the buffer tank body 1; simultaneously, the second support rod 8 is manually rotated, causing the first support rod 7 to rotate synchronously, rotating the second support rod 8 away from the buffer tank body 1 to an inclined state; then, the first locking screw 10 is loosened, and the second support rod 8 is pulled downwards so that its lower end is close to the ground, and then the first locking screw 10 is screwed into the first slot to fix it, preventing the second support rod 8 from loosening, thereby forming a lateral support for the buffer tank body 1 through the second support rod 8 to prevent it from tipping over. In the event of or about to tip over, the second support rod 8 can provide support; furthermore, when no movement is required, the second support rod 8 is inserted back into the first support rod 7 and rotated towards the buffer tank body 1 to reduce its overall volume, and finally screwed into the second locking screw 15 into the second slot to fix it, preventing the first support rod 7 from loosening.
