Description

Technical Field

[0001] The present invention belongs to the technical field of oxygen chambers, and particularly relates to a splicing type oxygen chamber sealing structure and a method for sealing and splicing an oxygen chamber. Background Art

[0002] When oxygen enters the lungs, it will immediately dissolve into the blood. Oxygen combines with hemoglobin in the blood to form oxyhemoglobin, and the blood transports oxyhemoglobin to the tissues and organs of the human body. The amount of oxygen dissolved in the blood of normal people is related to the environmental pressure. The amount of oxygen dissolved in the blood of a person in a hyperbaric oxygen chamber increases as the pressure of the oxygen chamber increases. Therefore, oxygen chambers are widely used in medical treatment, high-altitude oxygen inhalation, health care and other fields.

[0003] Splicing type oxygen chambers are widely used because their parts can be modularized, the volume of a single part is small, mass production is simple, assembly is convenient, transportation costs are low, the floor area for storage is small, maintenance is convenient, parts replacement is convenient, and they can be disassembled and transferred. In the prior art, splicing type oxygen chambers are sealed by sealing rubber strips. The disadvantage is that after the pressure of the oxygen chamber body becomes higher, the sealing rubber strips at the splicing joints of the chamber body are compressed and gaps appear, making it impossible to achieve sealing, and air leakage will occur in the oxygen chamber body.

[0004] At the same time, the sealing strips of the prior art can only be used to seal flat areas and cannot be used to seal corners. Due to the inflation and deformation of the oxygen chamber, gaps will appear at the corner splicing joints, and neither the sealing rubber strips nor the glue application can achieve the sealing effect. If glue is applied at the splicing joints, gaps will be generated due to deformation and the glue will tear. Summary of the Invention

[0012] Preferably, the number of the protrusions is three, and the cross-section of the protrusions is in an arc shape.

[0013] Preferably, the eighth side strip and the ninth side strip are respectively perpendicularly connected to the two vertical strip edges; the seventh side strip is perpendicularly connected to the transverse strip edge, and the tenth side strip is perpendicularly connected to the transverse strip edge.

[0026] The first seal 1 is integrally connected by an X-axis direction seal, a Y-axis direction seal, and a Z-axis direction seal, and the X-axis direction seal, the Y-axis direction seal, and the Z-axis direction seal are perpendicular to each other in space; the X-axis direction seal includes a first side strip 101 and a second side strip 102 that are perpendicularly connected to each other; the Y-axis direction seal includes a third side strip 103 and a fourth side strip 104 that are perpendicularly connected to each other; the Z-axis direction seal includes a fifth side strip 105 and a sixth side strip 106 that are perpendicularly connected to each other; the outer sides of the first side strip 101, the second side strip 102, the third side strip 103, the fourth side strip 104, the fifth side strip 105, and the sixth side strip 106 are integrally connected to the wing edge;

[0027] The second seal 2 includes a transverse seal 201. The transverse seal 201 includes a cross bar and two vertical bars. The two vertical bars are arranged in the middle part of the cross bar, and the two vertical bars are parallel to each other and perpendicular to the cross bar; the cross bar is perpendicularly connected to the seventh side strip 202 and the tenth side strip 205, and the two vertical bars are respectively perpendicularly connected to the eighth side strip 203 and the ninth side strip 204; the outer sides of the cross bar, the seventh side strip 202, the eighth side strip 203, the ninth side strip 204, and the tenth side strip 205 are integrally connected to the wing edge;

[0028] The third seal 3 includes a first U-shaped seal 301 and a second U-shaped seal 302. The first U-shaped seal 301 and the second U-shaped seal 302 are perpendicular to each other and connected by a bottom edge. The side edges of the first U-shaped seal 301 are perpendicularly connected to a first sealing strip 304 and a second sealing strip 305 respectively. The side edges of the second U-shaped seal 302 are perpendicularly connected to a third sealing strip 308 and a fourth sealing strip 309 respectively. The first sealing strip 304 is perpendicularly connected to a fifth sealing strip 303. The second sealing strip 305 is perpendicularly connected to a sixth sealing strip 306. The third sealing strip 308 is perpendicularly connected to a seventh sealing strip 307. The fourth sealing strip 309 is perpendicularly connected to an eighth sealing strip 310.

[0029] The fourth seal 4 includes two interconnected sealing strips, and the outer side of one of the sealing strips is integrally connected to the wing edge.

[0030] As Figure 1 shown, the first side strip 101 is integrally connected to the first wing edge 107.

[0031] Specifically, the material of the sealing structure is silicone.

[0032] Specifically, the number of the protrusions 5 is three, and the cross-section of the protrusions 5 is in an arc shape.

[0036] The present invention does not require gluing. Tightening with bolts can achieve the sealing effect because the sealing structure is in close contact with the splicing part, and when the pressure increases, the sealing structure will be pressed tighter.

[0037] The sealing structure of the present invention has low manufacturing cost, simple manufacturing process, environmentally friendly materials without peculiar smell, and is suitable for the sealing of splicing structures. The whole sealing structure is integrally formed of silica gel without splicing and will not leak air.

[0038] In the present invention, tests have also been carried out on other materials in terms of material selection. The EPDM material is relatively cheap, but it is not easy to process, especially for special-shaped structures, and the material is relatively easy to be damaged. The nitrile rubber has relatively poor elasticity and is not easy to be formed. The gluing method has relatively poor construction conditions because the gluing areas are all corners, and the uniformity of gluing cannot be guaranteed, and the reliability is not high. If secondary disassembly is required, it is difficult to clean and disassemble the gluing area, increasing the construction difficulty.

[0039] It can be understood that the above specific description of the present invention is only for explaining the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effect; as long as the use requirements are met, they are all within the protection scope of the present invention.
