Description

Technical Field

[0001] The utility model relates to the technical field of oxygen storage tanks, and specifically relates to an oxygen storage tank. Background Technique

[0002] In the oxygen production process, an oxygen storage tank is a bottle body used to store oxygen for supplying oxygen to patients.

[0003] According to a disclosed leak-proof oxygen storage tank (Publication No.: CN219828526U), in the above application, the valve plate is set to be in a horizontal state in the bottle mouth, and the valve plate seals the oxygen in the bottle mouth and the oxygen cylinder body. The sealing plug gradually approaches and contacts the valve plate to seal the worn gap between the valve plate and the bottle mouth due to long-term use and operation.

[0004] However, in the actual use process of the above device, although the sealing plug seals the worn gap between the valve plate and the bottle mouth due to long-term use and operation, the valve plate and the bottle mouth are in a state of rigid connection and friction, so that the sealing effect is not very good, and a worn gap will appear, resulting in the problem of oxygen leakage finally; in view of this, we have proposed an oxygen storage tank.

[0013] 1. When the oxygen storage tank is sealed daily, the two-way threaded rod can be rotated by turning the knob, causing the first sealing plate and the second sealing plate to move towards each other. When the first sealing plate and the second sealing plate are inserted into each other, the sliding rod will move up and down in the limiting groove, causing the pressing plate to continuously move up and down and squeeze the rubber plate. Eventually, when the first sealing plate and the second sealing plate move towards each other to close the ventilation port, the U-shaped insertion plate will be inserted into the U-shaped groove, and the rubber plate will be better sealed under the continuous up and down extrusion of the pressing plate.

Eventually, the sealing operation of multiple layers of colloids is realized, and the sealing effect is further improved. BRIEF DESCRIPTION OF THE DRAWINGS
