Description

Technical Field

[0001] The utility model relates to the technical field of hyperbaric oxygen chambers, and particularly relates to a sealing structure of a hyperbaric oxygen chamber. Background Technique

[0002] A hyperbaric oxygen chamber is a special medical device for hyperbaric oxygen therapy, which is mainly used clinically for the treatment of anaerobic infections, air embolism, decompression sickness, ischemic hypoxic encephalopathy, brain trauma, cerebrovascular diseases, etc. The scope of use of hyperbaric oxygen chambers is very wide, and they are important medical devices in each hospital.

[0003] Generally, the cabin door of a hyperbaric oxygen chamber is opened and closed by a simple hinge-type connection structure, and then sealed by a single structure of a sealing strip. This results in a low sealing performance of the cabin door. After long-term use, the insufficient elasticity of the sealing strip will deteriorate the sealing effect, thus affecting the sealing performance of the hyperbaric oxygen chamber. Therefore, we propose a sealing structure of a hyperbaric oxygen chamber to solve the problems raised above. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sealing structure of a hyperbaric oxygen chamber to solve the problem that after long-term use, the insufficient elasticity of the sealing strip will deteriorate the sealing effect, thus affecting the sealing performance of the hyperbaric oxygen chamber as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sealing structure of a hyperbaric oxygen chamber, including a cabin body;

[0006] It further includes:

[0007] A protruding frame, which is integrally formed on the outer surface of the cabin body. An inlet and outlet is integrally formed inside the protruding frame. A door frame is integrally formed on the inner side of the cabin body. The door frame is connected to the inlet and outlet, and the size of the door frame is larger than that of the inlet and outlet. A step groove is provided between the door frame and the inlet and outlet, and the size of the step groove is larger than that of the inlet and outlet. A door panel is provided inside the door frame. The door panel is opened and closed by a rotating shaft. A sealing plate is provided at the front end of the door panel, and the sealing plate is movably fitted inside the step groove.

[0008] Preferably, a threaded hole is provided in the middle of the door panel. A screw rod is provided at the rear end of the sealing plate. The screw rod is threadedly connected to the threaded hole, and the other end of the screw rod extends to the rear end of the door panel. A handle is provided at the rear end of the door panel.

[0009] Preferably, a limiting rod is provided at the rear end of the sealing plate. A limiting hole is provided on the surface of the door panel, and the limiting rod is snap-fitted with the limiting hole.

[0010] Preferably, the screw rod and the sealing plate are connected and limited by a bearing.

[0011] Preferably, a first gasket is provided inside the doorframe, and a second gasket is provided inside the step groove.

[0012] Preferably, the door panel is fixed inside the doorframe by a door lock.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing a protruding frame at the entrance of the cabin body, the installation thickness of the door panel is increased, so that when the door panel is closed, there is a thicker sealing effect. A three-layer frame structure of a doorframe, a step groove and an entrance and exit is provided, and a sealing plate is provided at the front end of the door panel. The sealing plate is hermetically engaged with the step groove, and the doorframe is hermetically engaged with the door panel, thereby forming a double-layer sealing structure to seal the cabin door, so as to achieve the sealing effect. The sealing plate moves telescopically through bolt connection. After the door panel and the doorframe are closed, the sealing plate can be moved by rotating the screw rod and abutted against the inside of the step groove to achieve the purpose of secondary sealing.

[0015] 2. By providing a limiting rod between the sealing plate and the door panel, the sealing plate can move through the limiting plate when moving, thereby improving the stability of the movement of the sealing plate. Moreover, the limiting plate and the screw rod are connected by a rotating shaft, so that the limiting plate is not affected when the screw rod rotates, which is convenient for the limiting plate to fit inside the step groove.
