Description

Technical Field

[0001] The present invention relates to a hyperbaric oxygen chamber technology, and more particularly to a hyperbaric oxygen chamber door transmission structure and a door installation method. Background Art

[0002] A hyperbaric oxygen chamber is a medical device that treats diseases by providing a pure oxygen environment at a higher pressure than normal. The chamber door, as a core component of hyperbaric oxygen therapy equipment, fulfills the important functions of sealing, pressure bearing, and safety assurance. Today's hyperbaric oxygen chamber doors are increasingly manufactured using high-strength alloy steel or composite materials to improve pressure bearing capacity. The door structure has been optimized to a quick-opening or sliding design, equipped with multiple safety interlocks to ensure it cannot be opened under abnormal pressure conditions, thus preventing safety accidents. However, such a door structure often occupies a large space inside the hyperbaric oxygen chamber when opening or closing, or results in a larger overall design and a larger footprint, making it difficult to use in small hyperbaric oxygen chambers. Furthermore, the door is difficult to maintain and install.

[0003] For example, Chinese patent publication number CN102988143B, published on June 11, 2014, is titled "A Hyperbaric Oxygen Chamber Door," comprising a door body, a door sealing rubber, a door frame, a pull-locking device and a pull-locking cylinder mounted above the door body, a main motion cylinder mounted on one side of the door body, a push-moving device mounted below the door body, a main motion device mounted below the push-moving device, and a push-locking device mounted between the push-moving devices. A push-locking device is mounted within the push-locking device, a left mechanical stopper is mounted on the left side of the left push-moving device, and a right mechanical stopper is mounted on the right side of the right push-moving device. This solution eliminates the need for manual locking, and the interior and exterior floors of the chamber are level, eliminating height differences. This ensures safer entry and exit for personnel and smoother entry and exit for stretchers. The door sealing rubber installed on the door body also ensures better airtightness. However, the cabin door structure design of this solution is complex, which will result in a larger volume of the hyperbaric oxygen chamber. In addition, the installation design of the cabin door is more complicated, which greatly increases the difficulty of installing and disassembling the cabin door. Summary of the Invention

[0004] The present invention overcomes the problems of complex structural design and space limitation of the existing hyperbaric oxygen chamber door, and provides a hyperbaric oxygen chamber door transmission structure. The door structure design of this solution is simple, and the door will not occupy the space inside the cabin when opening or closing the door in the hyperbaric oxygen chamber; further, the present invention also overcomes the problem of difficulty in assembling the existing hyperbaric oxygen chamber door, and provides a hyperbaric oxygen chamber door installation method. The door installation method in this solution is simple and convenient for later maintenance.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a hyperbaric oxygen chamber door transmission structure, comprising a door and a guide rail assembly provided at the bottom and top of the cabin, the guide rail assembly comprising a first guide rail and a second guide rail, the first guide rail and the second guide rail being arranged along the inner wall of the cabin and distributed at an angle, one end of the first guide rail is close to one end of the second guide rail and is located on the side of the second guide rail facing the cabin, the lateral ends of the door are respectively slidably connected to the first guide rail and the second guide rail, and the first guide rail and the second guide rail are provided with a limit assembly. In this solution, the first guide rail and the second guide rail provide support and sliding movement for the cabin door. The shapes of the first guide rail and the second guide rail are adapted to the shape of the interior of the hyperbaric oxygen chamber and are arranged along the shape of the inner wall of the hyperbaric oxygen chamber. In order to make the cabin door be located at the front side of the hyperbaric oxygen chamber when closed and at the left and right sides of the hyperbaric oxygen chamber when opened, the first guide rail and the second guide rail are designed to be arranged at an angle, and the bottom and top of the cabin door are respectively connected to the first guide rail and the second guide rail, so that the cabin door can rotate while moving along the guide rails, so that the cabin door can always be close to the front side and left or right side of the hyperbaric oxygen chamber during the opening and closing process, thereby reducing the cabin door's occupation of the internal space of the hyperbaric oxygen chamber during the opening and closing process, and can also reduce the footprint of the hyperbaric oxygen chamber. It is very suitable for small hyperbaric oxygen chambers.

[0006] Preferably, the limiting assembly includes a first limiting member and a second limiting member, wherein the first limiting member is provided on the first guide rail and the second limiting member is provided on the second guide rail. The first limiting member and the second limiting member are respectively used to limit the position of the cabin door on the first guide rail and the second guide rail to prevent the cabin door from falling off the guide rails.

[0007] Preferably, the top and bottom of the hatch are provided with a movable assembly, the movable assembly including a connecting seat, and the ends of the connecting seat are provided with a sliding structure adapted to the guide rail assembly. The top and bottom of the hatch are connected by the movable assembly and the guide rail assembly, respectively, so that the hatch moves to achieve opening and closing operations.

[0008] Preferably, the sliding structure is a roller or a sleeve. The use of a roller can effectively reduce the friction between the hatch door and the guide rail assembly, facilitating the opening and closing of the hatch door; the use of a slide can improve the movement stability of the hatch door on the guide rail assembly.

[0009] Preferably, the guide rail assembly located on the cabin bottom is provided with a stopper, comprising a stopper groove provided on the first guide rail or the second guide rail, an elastic member disposed within the stopper groove, and a stopper block disposed at one end of the elastic member proximate the stopper groove. The stopper is primarily used to limit the position of the hatch door when it is open, preventing the hatch door from moving freely when the hatch door is open.

[0010] Preferably, handles are provided on both the inner and outer sides of the door, and the handles are long and arranged horizontally. The handles facilitate users to push the door to move, and since the door is opened and closed horizontally, the handles are arranged in a horizontal direction.

[0011] A method for installing a hyperbaric oxygen chamber door includes the above-mentioned hyperbaric oxygen chamber door transmission structure, and the installation steps are as follows: S1: arranging guide rail assemblies on the bottom and top of the cabin along the inner wall of the hyperbaric oxygen chamber; S2: firstly matching the sliding structures on the same vertical side of the cabin door with the first guide rail or the second guide rail on the top and bottom respectively, and then matching the sliding structures on the other vertical side of the cabin door with the remaining set of guide rails respectively; S3: installing a limit assembly on the first guide rail and the second guide rail.

[0012] Preferably, in step S2, the hatch door is assembled on the same vertical side from the end of the first guide rail closer to the second guide rail, and on the other vertical side of the hatch door from the end of the second guide rail farther from the first guide rail. When assembling the hatch door, assembly is performed simultaneously on the first and second guide rails, and simultaneously on the guide rail assemblies on the cabin roof and cabin floor, thereby achieving a rapid assembly effect.

[0013] Preferably, in step S3, a first stopper is installed at an end of the first guide rail away from the second guide rail, and a second stopper is installed at an end of the second guide rail away from the first guide rail. The first stopper and the second stopper are used to limit the position of the door in the open state and the closed state to prevent the door from moving excessively and leaving the guide rails.

[0014] Preferably, after step S3 is completed, the door is repeatedly pushed until the door moves smoothly. Repeatedly pushing the door is used to detect whether the door is stable and to prevent abnormal resistance to door movement.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The transmission structure of the hatch is simple and the arrangement is simple, which enables the hatch to always move close to the inner wall of the hyperbaric oxygen chamber, reducing the space occupied by the hatch in the hyperbaric oxygen chamber during opening and closing; (2) The installation method of the hatch is simple, which enables the hatch to be quickly installed and disassembled, and facilitates the later maintenance of the hyperbaric oxygen chamber hatch; (3) It has safety assurance measures, which can effectively prevent the hatch from derailing and causing safety accidents; (4) It has an opening limit protection device to avoid the position of the hatch from changing when it is open, ensuring the normal entry and exit of personnel; (5) The overall manufacturing cost, installation cost and maintenance cost of the hatch are effectively reduced, with good economic benefits.

[0025] The technical solution of the present invention will be further described below with reference to specific embodiments and in conjunction with the accompanying drawings.

[0026] Example 1: Figures 1 to 8The transmission structure of the hyperbaric oxygen chamber door shown in the figure includes a guide rail assembly 2, which is arranged at the top and bottom positions of the hyperbaric oxygen chamber 15 entrance. The guide rail assembly 2 includes a first guide rail 3 and a second guide rail 4. The first guide rail 3 and the second guide rail 4 are arranged on both sides of the upper and lower sides of the entrance and exit of the hyperbaric oxygen chamber 15. The first guide rail 3 and the second guide rail 4 are arranged along the inner wall of the hyperbaric oxygen chamber 15. In this embodiment, the hyperbaric oxygen chamber 15 is a rectangular parallelepiped as a whole, so that the first guide rail 3 and the second guide rail 4 are arranged vertically. The first guide rail 3 is arranged at the entrance and exit of the hyperbaric oxygen chamber 15, and the second guide rail 4 is arranged on one side of the length direction of the hyperbaric oxygen chamber 15. A cabin is arranged between the upper and lower guide rail assemblies 2 of the hyperbaric oxygen chamber 15. The door 1, the lateral ends of the upper and lower parts of the cabin door 1 slide on the first guide rail 3 and the second guide rail 4 respectively; the first guide rail 3 and the second guide rail 4 are arranged close to the inner wall of the hyperbaric oxygen chamber 15, so that the lateral ends of the cabin door 1 will also move close to the inner wall of the hyperbaric oxygen chamber 15. Since the first guide rail 3 and the second guide rail 4 are also designed to be vertical, when the lateral sides of the cabin door 1 move on the first guide rail 3 and the second guide rail 4, they will also rotate along the inner wall of the hyperbaric oxygen chamber 15, so that the cabin door 1 will always be close to the inner wall of the hyperbaric oxygen chamber 15 during the opening and closing process, thereby reducing the occupation of the internal space of the hyperbaric oxygen chamber 15 by the cabin door 1 during the opening and closing process, which is particularly suitable for small hyperbaric oxygen chambers 15.

[0027] In this embodiment, the first guide rail 3 and the second guide rail 4 are both linear guide rails, adapted to the shape of the inner wall of the hyperbaric oxygen chamber 15, and the cross-sections of the first guide rail 3 and the second guide rail 4 can be rectangular or circular; the first guide rail 3 is arranged at the front side of the hyperbaric oxygen chamber 15, that is, the entrance side, and the second guide rail 4 is arranged at the side of the hyperbaric oxygen chamber 15. A limiting assembly 5 is provided on the first guide rail 3 and the second guide rail 4, and the limiting assembly 5 is used to limit the lateral ends of the cabin door 1 from detaching from the guide rail assembly 2. Specifically, on the first guide rail 3, the limiting assembly 5 is a first limiting member 6, and there are two first limiting members 6 arranged and respectively located at both ends of the first guide rail 3, and on the second guide rail 4, the limiting assembly 5 is a second limiting member 7, and there are two second limiting members 7 arranged and respectively located at both ends of the second guide rail 4; as shown Figure 3 As shown, the first limit member 6 and the second limit member 7 can also serve as the mounting parts of the first guide rail 3 and the second guide rail 4. The first limit member 6 and the second limit member 7 are plug-in structures. A mounting groove (not shown in the figure) structure is provided inside the hyperbaric oxygen chamber 15. The first guide rail 3 is inserted into the mounting groove through the first limit member 6 and is thereby mounted in the hyperbaric oxygen chamber 15. Similarly, the second guide rail 4 is inserted into the mounting groove through the second limit member 7 and is thereby mounted in the hyperbaric oxygen chamber 15.

[0028] In addition to the above installation methods, the guide rail assembly 2 can also be installed in the following ways: Figure 8As shown, mounting bases 16 are provided at the bottoms of the first and second guide rails 3 and 4. Mounting bases 16 and the guide rails are integrally structured, forming a C-shaped structure with the first and second guide rails 3 and 4, respectively. Mounting bases 16 are secured to the hyperbaric oxygen chamber 15, and the first and second guide rails 3 and 4 form a cantilever beam structure, which facilitates the installation of the cabin door 1 on the first and second guide rails 3 and 4. After the guide rail assembly 2 is installed, a support member 17 can be used to prevent the bottom of the guide rail assembly 2 from being subjected to a large bending moment. Finally, a stopper assembly 5 can be used to secure the support member 17. In this case, the stopper assembly 5 can be the support member 17 and the bottom of the C-shaped structure, which can prevent the sliding sleeve-type moving assembly from separating from the guide rails. The stopper assembly 5 can also be an independent stopper structure (not shown) arranged separately on the first and second guide rails 3 and 4 to prevent the roller-type moving assembly from separating from the guide rails. Of course, at this time, the mounting groove for mounting the guide rail assembly 2 in the hyperbaric oxygen chamber 15 is also a long strip structure for mounting the mounting base 16 on the first guide rail 3 and the second guide rail 4 .

[0029] A movable assembly is provided at the top and bottom of the hatch 1. The movable assembly includes a connecting seat 8 and two sliding structures 9. Specifically, the length of the connecting seat 8 is adapted to the transverse length of the hatch 1. The connecting seat 8 is fixedly connected to the bottom and top of the hatch 1. Steps are provided at both ends of the connecting seat 8. The step portions are provided with mounting holes 18 for mounting the sliding structures 9. Furthermore, the sliding structures 9 can be arranged in the form of a sliding sleeve 10 cooperating with the guide rail assembly 2, or in the form of a roller cooperating with the guide rail assembly 2.

[0030] In this embodiment, the sliding structure 9 is arranged in the form of a sliding sleeve 10. Figure 6 As shown, the sliding structure 9 includes a sleeve 10. A connecting shaft 20 is disposed on the outer circumference of the sleeve 10. The end of the connecting shaft 20, facing away from the sleeve 10, is threaded. The connecting shaft 20 is positioned within the mounting hole 18 of the connecting base 8 via two sets of bearings 21 and then secured by a nut 23 threadedly connected to the connecting shaft 20. A set of linear bearings 22 are also disposed within the sleeve 10 to ensure stable movement of the sleeve 10 on the guide rail assembly 2. Furthermore, driven by the connecting shaft 20 and bearings 21, the sleeve 10 is rotatably connected to the hatch door 1. As the sleeve 10 slides along the guide rail, the hatch door 1 can deflect on the guide rail to achieve sideways movement.

[0031] A stopper 11 is also provided on the first and second guide rails 3 and 4. When the hatch 1 is in the open state, the stopper 11 can limit the hatch 1, preventing the hatch 1 from shifting while open, which could affect the entry and exit of personnel. Specifically, the stopper 11 includes a stopper groove 12 disposed on the first and second guide rails 3 and 4. The stopper groove 12 is a cylindrical recessed structure arranged vertically on the surface of the guide rails. An elastic member is disposed within the stopper groove 12. The elastic member can be a circular spring structure. One end of the elastic member is connected to the bottom of the stopper groove 12, and the other end of the elastic member is connected to a stopper block 13, which is an elastic bead. In a normal state, the stopper 13, supported by the elastic member, is raised above the upper surface of the first guide rail 3 and the second guide rail 4. When the sliding structure 9 moves to contact the stopper 11, the stopper 13 is pressed downward into the stopper groove 12. When the sliding structure 9 moves away from the stopper 11, the stopper 13 is exposed again on the surface of the first guide rail 3 and the second guide rail 4. To facilitate the installation and effectiveness of the stopper 11, the stopper 11 is preferably arranged on the first guide rail 3 and the second guide rail 4 at the bottom of the hatch 1.

[0032] The hatch 1 is a one-piece curved structure, its curve adapted to the pressure within the hyperbaric oxygen chamber 15. Thinner connecting plates are located at the top and bottom of the door 1, while connecting slots are provided on the connecting base 8. The top and bottom of the door 1 are respectively plugged into the connecting slots of the connecting base 8, forming a fixed connection. The door 1 is also provided with a handle 14. Specifically, handles 14 are provided both inside and outside the door 1. The handles 14 are generally elongated, with the handles 14 positioned correspondingly on the inside and outside of the door 1. The handles 14 facilitate movement of the door 1 by the user. Since the door 1 opens and closes horizontally, the handles 14 are positioned horizontally.

[0033] The opening and closing process of the hatch 1 is as follows.

[0034] When the cabin door 1 is in a closed state, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 away from the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 close to the first guide rail 3; when the cabin door 1 is gradually opened, the bottom of the cabin door 1 is located at the end of the first guide rail 3 away from the second guide rail 4 and gradually moves toward the end of the first guide rail 3 close to the second guide rail 4, and the bottom of the cabin door 1 is located at the end of the second guide rail 4 close to the first guide rail 3 and gradually moves toward the end of the second guide rail 4 away from the first guide rail 3; after the cabin door 1 is fully opened, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 close to the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 away from the first guide rail 3; that is, the cabin door 1 moves from the front side position of the hyperbaric oxygen chamber 15 to the side position of the hyperbaric oxygen chamber 15.

[0035] When the cabin door 1 is in the open state, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 close to the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 away from the first guide rail 3; when the cabin door 1 is gradually closing, the bottom of the cabin door 1 is located at the end of the first guide rail 3 close to the second guide rail 4 and gradually moves toward the end of the first guide rail 3 away from the second guide rail 4, and the bottom of the cabin door 1 is located at the end of the second guide rail 4 away from the first guide rail 3 and gradually moves toward the end of the second guide rail 4 close to the first guide rail 3; after the cabin door 1 is completely closed, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 away from the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 close to the first guide rail 3; that is, the cabin door 1 moves from the side position of the hyperbaric oxygen chamber 15 to the front side position of the hyperbaric oxygen chamber 15.

[0036] Example 2: Figure 4 and Figure 5 The illustrated embodiment shows a transmission structure for a hyperbaric oxygen chamber door, comprising a guide rail assembly 2, which is arranged at the top and bottom of the entrance of the hyperbaric oxygen chamber 15. The guide rail assembly 2 comprises a first guide rail 3 and a second guide rail 4. The first guide rail 3 and the second guide rail 4 are arranged on both sides of the entrance and exit of the hyperbaric oxygen chamber 15, and the first guide rail 3 and the second guide rail 4 are arranged along the inner wall of the hyperbaric oxygen chamber 15. In this embodiment, the hyperbaric oxygen chamber 15 is cylindrical in shape as a whole, so that the first guide rail 3 and the second guide rail 4 are arranged at an angle, the first guide rail 3 is arranged at the entrance and exit of the hyperbaric oxygen chamber 15, the second guide rail 4 is arranged at the side of the entrance and exit of the hyperbaric oxygen chamber 15, and a guide rail 4 is arranged between the upper and lower guide rail assemblies 2 of the hyperbaric oxygen chamber 15. The hatch 1, the lateral ends of the upper and lower parts of the hatch 1 slide on the first guide rail 3 and the second guide rail 4 respectively; the first guide rail 3 and the second guide rail 4 are arranged close to the inner wall of the hyperbaric oxygen chamber 15, so that the lateral ends of the hatch 1 will also move close to the inner wall of the hyperbaric oxygen chamber 15. Since the first guide rail 3 and the second guide rail 4 are also designed at an angle, when the lateral sides of the hatch 1 move on the first guide rail 3 and the second guide rail 4, they will also rotate along the inner wall of the hyperbaric oxygen chamber 15, so that the hatch 1 will always be close to the inner wall of the hyperbaric oxygen chamber 15 during the opening and closing process, thereby reducing the occupation of the internal space of the hyperbaric oxygen chamber 15 by the hatch 1 during the opening and closing process, which is particularly suitable for small hyperbaric oxygen chambers 15.

[0037] In this embodiment, the first guide rail 3 and the second guide rail 4 are both arc-shaped guide rails, which are adapted to the shape of the inner wall of the hyperbaric oxygen chamber 15. The cross-sections of the first guide rail 3 and the second guide rail 4 can be rectangular or circular; the first guide rail 3 is arranged at the front side of the hyperbaric oxygen chamber 15, that is, the entrance side, and the second guide rail 4 is arranged at the side of the hyperbaric oxygen chamber 15. A limiting assembly 5 is provided on the first guide rail 3 and the second guide rail 4, and the limiting assembly 5 is used to limit the lateral ends of the cabin door 1 from detaching from the guide rail assembly 2. Specifically, on the first guide rail 3, the limiting assembly 5 is a first limiting member 6, and there are two first limiting members 6 arranged and respectively located at the two ends of the first guide rail 3, and on the second guide rail 4, the limiting assembly 5 is a second limiting member 7, and there are two second limiting members 7 arranged and respectively located at the two ends of the second guide rail 4; as shown Figure 5 As shown, the first limit member 6 and the second limit member 7 can also serve as the mounting parts of the first guide rail 3 and the second guide rail 4. The first limit member 6 and the second limit member 7 are plug-in structures. A mounting groove (not shown in the figure) structure is provided inside the hyperbaric oxygen chamber 15. The first guide rail 3 is inserted into the mounting groove through the first limit member 6 and is thereby mounted in the hyperbaric oxygen chamber 15. Similarly, the second guide rail 4 is inserted into the mounting groove through the second limit member 7 and is thereby mounted in the hyperbaric oxygen chamber 15.

[0038] In addition to the above installation methods, the guide rail assembly 2 can also be installed in the following ways: Figure 8 As shown, mounting bases 16 are provided at the bottoms of the first and second guide rails 3 and 4. Mounting bases 16 and the guide rails are integrally structured, so that the first and second guide rails 3 and 4 form a C-shaped structure. Mounting bases 16 are secured to the hyperbaric oxygen chamber 15. The first and second guide rails 3 and 4 then form a cantilever beam structure, facilitating the installation of the hatch 1 on the first and second guide rails 3 and 4. After the guide rail assembly 2 is installed, a support 17 can be employed to prevent the bottom of the guide rail assembly 2 from being subjected to a large bending moment. Finally, a stopper assembly 5 is employed to secure the support 17. The stopper assembly 5 can be the support 17 and the bottom of the C-shaped structure, which prevent the sliding sleeve-type moving assembly from separating from the guide rails. The stopper assembly 5 can also be an independent stopper structure (not shown) disposed separately on the first and second guide rails 3 and 4 to prevent the roller-type moving assembly from separating from the guide rails. Of course, at this time, the mounting groove for mounting the guide rail assembly 2 in the hyperbaric oxygen chamber 15 is also a long strip structure for mounting the mounting base 16 on the first guide rail 3 and the second guide rail 4 .

[0039] A movable assembly is provided at the top and bottom of the hatch 1. The movable assembly includes a connecting seat 8 and two sliding structures 9. Specifically, the length of the connecting seat 8 is adapted to the transverse length of the hatch 1. The connecting seat 8 is fixedly connected to the bottom and top of the hatch 1. Steps are provided at both ends of the connecting seat 8. The step portions are provided with mounting holes 18 for mounting the sliding structures 9. Furthermore, the sliding structures 9 can be arranged in the form of a sliding sleeve cooperating with the guide rail assembly 2, or in the form of a roller 19 cooperating with the guide rail assembly 2.

[0040] In this embodiment, the sliding structure 9 is arranged in the form of rollers 19, such as Figure 7 As shown, the sliding structure 9 includes a roller 19 and a connecting bracket 24. The connecting bracket 24 has a shaft at one end and a U-shaped groove at the other. Hinge holes are provided at both ends of the U-shaped groove of the connecting bracket 24. The roller 19 is rotatably connected to the U-shaped groove of the connecting bracket 24 via the hinge shaft, thereby enabling the roller 19 to rotate. The end of the shaft of the connecting bracket 24, away from the U-shaped groove, is threaded. The shaft of the connecting bracket 24 is arranged in the mounting hole 18 of the connecting base 8 via two sets of bearings 21 and then secured by a nut 23 connected to the threaded connection on the shaft. The use of the roller 19 for movement significantly reduces the resistance of the cabin door 1 to movement on the guide rail. Furthermore, the roller 19, driven by the connecting bracket 24 and bearings 21, can also rotate around the cabin door 1 structure, forming a universal wheel structure. The circumferential surface of the roller 19 is provided with a mating groove for mating with the guide rail.

[0041] A stopper 11 is also provided on the first and second guide rails 3 and 4. When the hatch 1 is in the open state, the stopper 11 can limit the hatch 1, preventing the hatch 1 from shifting while open, which could affect the entry and exit of personnel. Specifically, the stopper 11 includes a stopper groove 12 disposed on the first and second guide rails 3 and 4. The stopper groove 12 is a cylindrical recessed structure arranged vertically on the surface of the guide rails. An elastic member is disposed within the stopper groove 12. The elastic member can be a circular spring structure. One end of the elastic member is connected to the bottom of the stopper groove 12, and the other end of the elastic member is connected to a stopper block 13, which is an elastic bead. In a normal state, the stopper 13, supported by the elastic member, is raised above the upper surface of the first guide rail 3 and the second guide rail 4. When the sliding structure 9 moves to contact the stopper 11, the stopper 13 is pressed downward into the stopper groove 12. When the sliding structure 9 moves away from the stopper 11, the stopper 13 is exposed again on the surface of the first guide rail 3 and the second guide rail 4. To facilitate the installation and effectiveness of the stopper 11, the stopper 11 is preferably arranged on the first guide rail 3 and the second guide rail 4 at the bottom of the hatch 1.

[0042] The hatch 1 is a one-piece curved structure, its curve adapted to the pressure within the hyperbaric oxygen chamber 15. Thinner connecting plates are located at the top and bottom of the door 1, while connecting slots are provided on the connecting base 8. The top and bottom of the door 1 are respectively plugged into the connecting slots of the connecting base 8, forming a fixed connection. The door 1 is also provided with a handle 14. Specifically, handles 14 are provided both inside and outside the door 1. The handles 14 are generally elongated, with the handles 14 positioned correspondingly on the inside and outside of the door 1. The handles 14 facilitate movement of the door 1 by the user. Since the door 1 opens and closes horizontally, the handles 14 are positioned horizontally.

[0043] The opening and closing process of the hatch 1 is as follows.

[0044] When the cabin door 1 is in a closed state, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 away from the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 close to the first guide rail 3; when the cabin door 1 is gradually opened, the bottom of the cabin door 1 is located at the end of the first guide rail 3 away from the second guide rail 4 and gradually moves toward the end of the first guide rail 3 close to the second guide rail 4, and the bottom of the cabin door 1 is located at the end of the second guide rail 4 close to the first guide rail 3 and gradually moves toward the end of the second guide rail 4 away from the first guide rail 3; after the cabin door 1 is fully opened, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 close to the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 away from the first guide rail 3; that is, the cabin door 1 moves from the front side position of the hyperbaric oxygen chamber 15 to the side position of the hyperbaric oxygen chamber 15.

[0045] When the cabin door 1 is in the open state, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 close to the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 away from the first guide rail 3; when the cabin door 1 is gradually closing, the bottom of the cabin door 1 is located at the end of the first guide rail 3 close to the second guide rail 4 and gradually moves toward the end of the first guide rail 3 away from the second guide rail 4, and the bottom of the cabin door 1 is located at the end of the second guide rail 4 away from the first guide rail 3 and gradually moves toward the end of the second guide rail 4 close to the first guide rail 3; after the cabin door 1 is completely closed, one end of the bottom of the cabin door 1 is located at the end of the first guide rail 3 away from the second guide rail 4, and the other end of the bottom of the cabin door 1 is located at the end of the second guide rail 4 close to the first guide rail 3; that is, the cabin door 1 moves from the side position of the hyperbaric oxygen chamber 15 to the front side position of the hyperbaric oxygen chamber 15.

[0046] Example 3: A method for installing a hyperbaric oxygen chamber door is implemented using the hyperbaric oxygen chamber door transmission structure in Example 1 or Example 2.

[0047] First, select an appropriate guide rail assembly 2 based on the shape of the hyperbaric oxygen chamber 15. Since the first guide rail 3 and the second guide rail 4 are respectively arranged at the front entrance and exit and on the side of the hyperbaric oxygen chamber 15, close to the inner wall, the shapes of the first guide rail 3 and the second guide rail 4 must be compatible with the shape of the hyperbaric oxygen chamber 15. If the hyperbaric oxygen chamber 15 is an overall rectangular parallelepiped, the first guide rail 3 and the second guide rail 4 can be linear guides; if the hyperbaric oxygen chamber 15 is an overall cylindrical shape, the first guide rail 3 and the second guide rail 4 can be curved guides. This embodiment uses a rectangular hyperbaric oxygen chamber 15 as an example, but the same principle applies to a cylindrical chamber.

[0048] Secondly, guide rail assemblies 2 are arranged along the inner wall of the hyperbaric oxygen chamber 15 at the bottom and top of the chamber. Guide rail assemblies 2 are arranged on the bottom (bottom plate) of the hyperbaric oxygen chamber 15 to support and limit the position of the door 1, and on the top (top plate) of the hyperbaric oxygen chamber 15 to limit the position of the door 1. The two sets of guide rail assemblies 2 enable the door 1 to be stably arranged within the hyperbaric oxygen chamber 15 and to be movable. Furthermore, a first guide rail 3 is arranged at the front entrance and exit of the hyperbaric oxygen chamber 15 (the first guide rail 3 is arranged at both the top and bottom of the hyperbaric oxygen chamber 15). Furthermore, a second guide rail 4 is arranged on the side of the hyperbaric oxygen chamber 15 near the entrance and exit (the second guide rail 4 is arranged at both the top and bottom). On the side where the second guide rail 4 and the first guide rail 3 are close to each other, the second guide rail 4 is closer to the side of the hyperbaric oxygen chamber 15. Mounting grooves are provided at the positions where the guide rail assemblies 2 are arranged in the hyperbaric oxygen chamber 15. The mounting grooves can adapt to the mounting portions on the first guide rails 3 and the second guide rails 4. When the first guide rails 3 and the second guide rails 4 are arranged on the mounting grooves, preliminary positioning and fixation can be achieved, and the positions of the first guide rails 3 and the second guide rails 4 will protrude as a whole from the outside of the bottom plate and the top plate to cooperate with the sliding structure 9 on the cabin door 1.

[0049] Then, the movable assembly is installed at the top and bottom of the hatch door 1. The movable assembly can be in the form of a sleeve or a roller. In this embodiment, the roller form is used for the description (the installation method for the sleeve form is the same). The upper and lower rollers 19 on the same side of the hatch door 1 are respectively engaged with the upper and lower first guide rails 3, which are closer to the second guide rail 4. To prevent the second guide rail 4 from interfering with the engagement of the rollers on the first guide rail 3, a certain distance is maintained between the first and second guide rails 3, 4 to accommodate the rollers 19. After the upper and lower rollers 19 on the same side of the hatch door 1 are engaged with the first guide rails 3, the hatch door 1 is rotated so that the engagement position between the upper and lower first guide rails 3 on one side of the hatch door 1 remains fixed. The upper and lower rollers 19 on the other side are rotated to the end of the second guide rail 4 away from the first guide rail 3. The upper and lower rollers 19 are then engaged with the upper and lower second guide rails 4, respectively. At this point, the hatch door 1 is preliminarily installed on the upper and lower guide rail assemblies 2 and is in the open position.

[0050] Then, two sets of first limit members 6 are installed at both ends of the first guide rail 3, and two sets of second limit members 7 are installed at both ends of the second guide rail 4. The first limit members 6 and the second limit members 7 are used to prevent the sliding structure 9 on the cabin door 1 from detaching from the first guide rail 3 and the second guide rail 4, so as to avoid the cabin door 1 derailing and causing a safety accident.

[0051] Finally, the hatch door 1 is repeatedly pushed on the guide rail assembly 2 and the guide rail assembly 2 is completely fixed at the same time until there is no abnormal resistance when the hatch door 1 moves on the guide rail assembly 2, and the installation of the hatch door 1 is completed.

[0052] This method greatly reduces the installation difficulty of the cabin door 1, can realize the rapid disassembly and assembly of the cabin door 1, and facilitates the maintenance of the cabin door 1 of the hyperbaric oxygen chamber 15.
