Description

Technical Field

[0001] The invention relates to the technical field of oxygen chambers, in particular to a door installation structure of a hyperbaric oxygen chamber. Background Art

[0002] The oxygen chamber is a special medical device for high-pressure oxygen therapy. Its principle is to place the user in an oxygen-rich environment with a pressure higher than normal atmospheric pressure. Under the action of high pressure, oxygen is input into the respiratory and microcirculatory systems and reaches various organs of the human body, increasing the level of arterial oxygen partial pressure and oxygen saturation to promote human metabolism. The oxygen chamber door is a necessary moving part for entering and exiting the oxygen chamber and is the core component for achieving the sealing of the oxygen chamber.

[0003] At present, the commonly used oxygen cabin doors are mostly made of transparent organic glass or PC. For oxygen cabins with higher pressure, they are mostly designed with arc appearance in consideration of pressure bearing capacity. Considering that the cabin door needs to move relative to the cabin body when opening or closing, a hole is generally opened at the edge of the cabin door, and a structural part is fixed on it to connect the guide rail and cylinder and other devices. However, the above door fixing method has the following defects: (1) When the pressure in the cabin increases, the cabin pressure has a large thrust on the cabin door, which will cause the cabin door to be slightly deformed. Since the connection between the cabin door and the structural part is usually a rigid connection, this may cause local internal stress to occur, resulting in the risk of cabin door rupture. In addition, since the cabin door is mostly molded or hot-bent, it is necessary to drill holes to connect and fix the structural parts after the first processing is completed, which is equivalent to secondary processing. At this time, if the processing technology is poor, it will lead to processing defects and hidden cracks and other safety hazards, thereby increasing the risk of cabin door rupture. (2) As a pressure-bearing component, the hatch door is constantly subjected to stress and release during use, which accelerates its aging degree. Or it may be scratched or damaged during use. When the hatch door needs to be replaced, it is generally necessary to frequently remove multiple bolts to remove the hatch door connector and then replace the new hatch door with the connector. This process is often cumbersome, and the bolts may not be installed or tightened properly during the process, making maintenance difficult. Summary of the invention

[0004] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions.

[0005] A hyperbaric oxygen chamber door installation structure is designed, comprising a door body arranged at the entrance and exit of the cabin, a circle of sealing strips is arranged between the door body and the inner wall of the cabin, a fixing box with one side opening is arranged at the front and rear ends of the door body, a group of buffer components is arranged on each inner wall of the fixing box, and the buffer components on both sides and both ends of the fixing box are symmetrically arranged, the side edges at both ends of the door body are respectively embedded in the fixing box, and each group of buffer components is in contact with the door body, and sliding blocks cooperating with the internal guide rails of the cabin body are symmetrically arranged at both ends of the bottom surface of the fixing box;

[0006] The buffer assembly includes a buffer plate, through holes respectively opened at the four corners of the upper end of the buffer plate, mounting tubes respectively connected to the bottoms of the through holes, a ball rolling in the mounting tube, an H-shaped sleeve sleeved on the outside of the mounting tube, a mounting plate arranged below the H-shaped sleeve, and a buffer spring connected between the H-shaped sleeve and the mounting plate. The mounting plate is fixed in a fixing box, and a cavity for accommodating ball one is formed between the mounting tube and the H-shaped sleeve, and the upper surface of the ball one is exposed through the through hole.

[0007] Preferably, a plurality of balls 2 are distributed in an array on the buffer plates located at both ends and the bottom of the fixing box.

[0008] Preferably, the installation method of the ball 2 is the same as the installation structure of the ball 1 at the four corners of the buffer plate.

[0009] Preferably, the H-shaped sleeve is threadedly connected or interference-fitted with the mounting tube.

[0010] Preferably, a mounting hole is provided on the mounting plate.

[0011] Preferably, the sealing strip is an inflatable strip, and an inflation port is provided on one side of the sealing strip.

[0012] The beneficial effects of the present invention are:

[0013] 1. The hatch body of the present invention adopts a hole-free design and can be installed after only one processing and forming, which greatly simplifies the production process of the hatch, reduces the manufacturing cost, and makes subsequent maintenance work more convenient and quick, thereby improving economy and maintainability.

[0014] 2. By setting an inflatable sealing strip between the hatch body and the inner wall of the cabin, when the strip is inflated, it can effectively seal the gap between the hatch and the cabin, ensure the stability of the pressure inside the cabin, prevent oxygen leakage, and improve the efficiency and safety of the hyperbaric oxygen chamber.

[0015] 3. A buffer assembly is set in the fixed box, which provides a stable support system for the hatch body through the combination of balls and buffer springs. The balls can reduce friction, and the buffer springs can absorb impact force, avoiding internal stress on the edge of the hatch, reducing the risk of hatch damage, and improving the stability and durability of the structure.

[0016] 4. The door body cooperates with the guide rail in the cabin through the fixing box and the slider, making the door easier to disassemble and assemble. You only need to remove the guide rail on one side to easily take out the door body for replacement or repair, which reduces the difficulty of operation and improves work efficiency.

[0017] 5. When the pressure in the cabin increases, the door body can move appropriately with the pressure change under the action of the buffer spring, avoiding damage that may be caused by rigid connection. This design ensures the freedom and safety of the door during the pressure increase process and eliminates the safety hazard of door damage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] Example 1

[0033] A hyperbaric oxygen chamber door installation structure, such as Figures 1 to 12 As shown, it includes a door body 4 arranged at the entrance and exit of the cabin body 2. The door body 4 is of a hole-free design and can be installed after only one processing and forming, making the processing and maintenance of the door body 4 more convenient, and improving the economy and maintainability; a circle of sealing strip 7 is provided between the door body 4 and the inner wall of the cabin body 2, and the sealing strip 7 is an inflatable strip, the top of the strip is designed with an elliptical hollow, and an inflation port 5 is provided on one side of the sealing strip 7. A fixing box 3 with one side opening is respectively provided at the front and rear ends of the hatch body 4. The fixing box 3 is a sheet metal box. A set of buffer components 8 is respectively provided on each inner wall of the fixing box 3. The buffer components 8 at both sides and both ends of the fixing box 3 are symmetrically arranged. The sides of the hatch body 4 at both ends are respectively embedded in the fixing box 3. The edges of the hatch body 4 at both ends are inserted into the fixing box 3 to a certain depth to prevent the hatch body 4 from being pressed and moving when the pressure inside the cabin 2 is increased so that the two ends are moved out of the fixing box 3. Each set of buffer components 8 is in contact with the hatch body 4. Slide blocks 6 cooperating with the internal guide rails 1 of the cabin 2 are respectively symmetrically provided at both ends of the bottom surface of the fixing box 3. The fixing box 3 can be moved along the guide rails 1 in the cabin 2 through the slide blocks 6. When the hatch body 4 is disassembled, it is only necessary to remove the guide rails 1 on one side of the cabin 2 as a whole, and then take out the two ends of the hatch body 4 from the fixing box 3 for replacement, so that the disassembly and assembly of the hatch body 4 is more convenient to operate.

[0034] The buffer assembly 8 includes a buffer plate 81, through holes respectively opened at the four corners of the upper end of the buffer plate 81, mounting tubes 83 respectively connected to the bottom of the through holes, a ball 82 rolling in the mounting tube 83, an H-shaped sleeve 84 sleeved on the outside of the mounting tube 83, a mounting plate 86 arranged below the H-shaped sleeve 84, and a buffer spring 85 connected between the H-shaped sleeve 84 and the mounting plate 86. The bottom guide edge design in the through hole has a back that is integrally connected with the mounting tube 83. The mounting tube 83 is a raised step-shaped cavity design extending downward from the back of the hole. A threaded mounting hole 88 is opened on the mounting plate 86 to fix it in the fixing box 3. A cavity for accommodating the ball 82 is formed between the mounting tube 83 and the H-shaped sleeve 84. The upper surface of the ball 82 is exposed from the through hole. The side of the hatch body 4 can contact with the ball 82 in the fixing box 3, thereby reducing the friction between it and the buffer plate 81. The H-shaped sleeve 84 is threadedly connected or interference fit with the mounting tube 83. When the buffer spring 85 is installed, a mounting column 87 can be provided on the H-shaped sleeve 84 and the mounting plate 86, and the two ends of the buffer spring 85 are respectively sleeved on the mounting column 87, so as to facilitate the installation and assembly of the entire structure.

[0035] A plurality of balls 89 are arranged in an array on the buffer plate 81 at both ends and the bottom of the fixed box 3. The installation method of the balls 89 is the same as the installation structure of the balls 82 at the four corners of the buffer plate 81. The combination of balls and springs can provide a stable support system. The balls can evenly distribute the load, while the buffer springs 85 can appropriately expand and contract according to the change of the load to maintain the balance of the structure. The balls reduce sliding friction through rolling friction, thereby reducing wear. The buffer springs 85 further reduce wear by absorbing impact force and reducing direct collisions between structural components. Thereby improving the stability and durability of the structure. When the pressure in the cabin 2 increases, the sides of the two ends of the door body 4 will be displaced in different directions. The buffer plate 81 moves with the door body 4 under the action of the buffer springs 85, so that no rigid force is generated between the door body 4 and the fixed box 3, thereby avoiding the generation of stress in the edge of the door, thereby reducing the risk of damage to the door body 4.

[0036] When the present invention is actually used, the assembled buffer assembly 8 is fixed to each inner wall of the fixing box 3 through the mounting holes 88 on the mounting plate 86. When the rubber strip is not inflated, there is a gap between the hatch body 4 and the rubber strip, and the hatch body 4 can slide freely along the guide rail 1, so that the hatch can be in an open or closed state, so that people can enter and exit; when the rubber strip is inflated, the rubber strip bulges to seal the gap between the hatch body 4 and the rubber strip, so that the hatch body 4 can seal the inside of the cabin 2. When the cabin 2 is inflated, the cabin pressure is It rises and exerts a force on the hatch body 4. At this time, after the rubber strip is deflated, the hatch body 4 still relies on the pressure inside the cabin to achieve sealing. As the pressure increases, the pressure of the hatch body 4 on the rubber strip becomes greater and the degree of extrusion increases, so that the upper and lower edges of the hatch will be displaced to varying degrees under the action of the buffer spring 85, so that the hatch body 4 does not have a rigid connection, thereby ensuring the freedom of edge displacement during the pressure increase process inside the cabin 2, thereby eliminating the internal stress on the sides of the door body 4 at both ends and reducing the safety hazard of door damage.
