Technical Field
[0001] This utility model relates to a hyperbaric oxygen chamber design, and more specifically, to a hyperbaric oxygen chamber door structure and a hyperbaric oxygen chamber. Background Technology
[0002] Existing hyperbaric oxygen chamber doors generally use a sliding door method to open and close, or a hinged door method, rotating the door 90° to 180° to open and close. Both of these methods are only suitable for large hyperbaric oxygen chambers. For small hyperbaric oxygen chambers, opening the door will either occupy space inside the chamber, preventing the user from opening the door from the front, or it will increase the floor space of the chamber, making it unsuitable for small hyperbaric oxygen chambers.
[0003] For example, Chinese Patent Publication No. CN2011977861, published on February 25, 2009, is entitled "A Top-Opening Hyperbaric Oxygen Chamber." It includes a chamber body with a top-opening door structure. The door is located on the upper surface of the chamber body, and the chamber body and door are connected by a connecting device. The chamber body's external shape is suitable for lying or reclining positions. The door opens to the left and right or front and back. The connecting device includes a hinge and a pneumatic opening mechanism. This design offers a spacious interior, increased usable space, and features safety, reliability, advanced technology, and comfort. The top-opening chamber structure is suitable for various medical equipment such as hyperbaric oxygen chambers, pressurized chambers, and negative pressure chambers. While the hinged hinge-type door structure in this design does not affect the floor space of the hyperbaric oxygen chamber, it is not suitable for some upright hyperbaric chambers, as it would significantly increase the floor space required for upright hyperbaric chambers. Utility Model Content
[0004] This invention overcomes the problem of large space occupation of upright hyperbaric oxygen chamber doors in hyperbaric oxygen chambers, and provides a hyperbaric oxygen chamber door structure and a hyperbaric oxygen chamber. The hyperbaric oxygen chamber does not increase the floor space of the hyperbaric oxygen chamber when the door is open or closed, nor does it affect the internal space of the hyperbaric oxygen chamber. The door is suitable for hyperbaric oxygen chambers of various sizes and shapes, as well as other types of doors.
[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a hyperbaric oxygen chamber door structure, including a first guide rail assembly, a second guide rail assembly, and a door. The first guide rail assembly includes a first guide rail and a second guide rail, which are arranged at an angle. The second guide rail assembly includes a third guide rail parallel to either the first or second guide rail. Mounting seats are provided at both ends of the door, and movable components are provided on the mounting seats. The door is slidably connected to the first guide rail assembly and the second guide rail assembly respectively through the movable components at both ends. In this solution, the first and second guide rail assemblies provide installation and support for the door, and also allow the door to move, enabling it to open and close. The angled arrangement of the first and second guide rails in the first guide rail assembly ensures that the door rotates to a certain extent while sliding on the guide rails, rotating the door to the inner wall of the hyperbaric oxygen chamber, thus achieving door opening and closing without affecting the floor space inside or outside the chamber.
[0006] Preferably, the first and second guide rails are linear guide rails, arranged at right angles. Designing the first and second guide rails as linear guide rails allows for the adaptation to the layout of some square hyperbaric oxygen chambers, in which case the first and second guide rails are arranged at right angles.
[0007] Preferably, the first and second guide rails are arc-shaped guide rails. The arc-shaped design of the first and second guide rails can accommodate the layout of some cylindrical hyperbaric oxygen chambers.
[0008] Preferably, the second guide rail assembly further includes a fourth guide rail, and the second guide rail assembly is arranged in the same way as the first guide rail assembly. The inclusion of a fourth guide rail in the second guide rail assembly, with the first and second guide rail assemblies arranged identically, improves the stability of the hatch installation.
[0009] Preferably, the moving component includes a guide sleeve that is slidably connected to the first guide rail assembly or the second guide rail assembly, and the guide sleeve is rotatably connected to the hatch. The moving component employs a guide sleeve structure, and the hatch is slidably connected to the first guide rail assembly or the second guide rail assembly through the guide sleeve structure. This improves the stability of the hatch movement and ensures stability when the hatch is open or closed.
[0010] Preferably, the moving component includes a roller that is adapted to and rolls in connection with the first guide rail assembly or the second guide rail assembly, and the roller is rotatably connected to the hatch. The moving component employs a roller structure, and the hatch is slidably connected to the first guide rail assembly or the second guide rail assembly via the roller structure. This helps reduce friction during hatch movement and allows for better opening and closing of the hatch.
[0011] Preferably, the first guide rail assembly or the second guide rail assembly is provided with a limiting component. The limiting component includes a spring bead and a limiting mounting seat disposed within the first guide rail assembly or the second guide rail assembly. The spring bead is disposed on the guide rail, and the limiting mounting seat is disposed at both ends of the guide rail. The limiting components on the first guide rail assembly and the second guide rail assembly can limit the hatch. When the hatch is in the positioned state, it can prevent the hatch from moving on its own or from derailing, thus ensuring the stability of the hatch.
[0012] Preferably, the hatch is equipped with handles on both its inner and outer surfaces. Handles are provided on both the inner and outer sides of the hatch, making it convenient for personnel to open the hatch from the inside or outside.
[0013] A hyperbaric oxygen chamber includes the aforementioned hyperbaric oxygen chamber door structure. The hyperbaric oxygen chamber includes a door frame portion, and a first guide rail assembly and a second guide rail assembly are arranged inside the hyperbaric oxygen chamber corresponding to the door frame portion. The door frame portion on the hyperbaric oxygen chamber is used to install the door structure. The first guide rail assembly and the second guide rail assembly are respectively arranged at the door frame portion, and arranging them inside the hyperbaric oxygen chamber can reduce the external footprint of the hyperbaric oxygen chamber.
[0014] Preferably, a sealing strip is also provided between the hatch and the door frame. The sealing strip achieves a seal between the hatch and the door frame, thereby ensuring the sealing effect inside the hyperbaric oxygen chamber.
[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) This solution can not increase the floor area of the hyperbaric oxygen chamber when the door is open or closed, nor will it affect the interior space of the hyperbaric oxygen chamber; (2) It is applicable to hyperbaric oxygen chambers of various sizes and shapes as well as other types of doors; (3) It has a limiting effect, which can prevent the door from closing automatically when the door is open, and has good stability; (4) The door can be arbitrarily adjusted according to the shape of the chamber, and can be installed on any chamber to realize the function of opening and closing the hyperbaric oxygen chamber door; (5) It has a simple structure, simple layout, is easy to implement and produce, and has good practicality.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0026] Example 1: As Figures 1 to 3 The diagram shows a hyperbaric oxygen chamber door structure, including a door 3, a first guide rail assembly 1, and a second guide rail assembly 2. The bottom and top of the door 3 are slidably connected to the first guide rail assembly 1 and the second guide rail assembly 2, respectively. The first guide rail assembly 1 is arranged horizontally at the bottom of the door 3, and the second guide rail assembly 2 is arranged horizontally at the top of the door 3. The first guide rail assembly 1 includes a first guide rail 1.1 and a second guide rail 1.2, which are arranged at right angles. Movable components 6 are provided at the bottom and top of the door 3, respectively, and are slidably connected to the first guide rail assembly 1 and the second guide rail assembly 2, thereby allowing the door 3 to move along the guide rails and realize the opening and closing of the door.
[0027] Specifically, such as Figure 1As shown, the first guide rail assembly 1 is arranged at the bottom of the hatch 3, and the second guide rail assembly 2 is arranged at the top of the hatch 3, both of which are located inside the high-pressure chamber. Specifically, in the first guide rail assembly 1, the first guide rail 1.1 is positioned when the hatch 3 is closed (at the hatch frame opening), and the second guide rail 1.2 is positioned when the hatch 3 is open (on the inner side of the high-pressure chamber). The second guide rail assembly 2 includes a third guide rail 2.1 and a fourth guide rail 2.2. The third guide rail 2.1 corresponds to the position of the first guide rail 1.1 and is located at the top of the hatch 3, and the fourth guide rail 2.2 corresponds to the position of the second guide rail 1.2 and is also located at the top of the hatch 3.
[0028] It should be noted that in the second guide rail assembly 2, only the third guide rail 2.1 can be used. When the hatch 3 is connected to the first guide rail assembly 1 and the second guide rail assembly 2, the two bottom ends of the hatch 3 are slidably connected to the first guide rail 1.1 and the second guide rail 1.2 respectively. Under the action of gravity, the bottom of the hatch 3 forms stable connection points with the first guide rail 1.1 and the second guide rail 1.2 respectively. The top end of the hatch 3 is slidably connected to the third guide rail 2.1. At this time, the hatch 3 has three movement points, which can ensure the stable movement of the hatch 3. In this scheme, the third guide rail 2.1 can correspond to the position of the first guide rail 1.1 or the second guide rail 1.2. In this embodiment, only the second guide rail assembly 2 including the third guide rail 2.1 and the fourth guide rail 2.2 is used as an example for explanation.
[0029] The first guide rail 1.1 and the second guide rail 1.2 are both linear guide rails, as are the third guide rail 2.1 and the fourth guide rail 2.2. This design is suitable for a cuboid-shaped hyperbaric oxygen chamber. In this case, the first guide rail 1.1 and the second guide rail 1.2 are arranged at right angles, as are the third guide rail 2.1 and the fourth guide rail 2.2.
[0030] Furthermore, the hyperbaric oxygen chamber door 3 is an integral curved door (mainly curved in the vertical direction, with the convex surface facing outwards from the hyperbaric oxygen chamber), enabling it to withstand the high-pressure environment better. Mounting seats 4 are respectively provided at the top and bottom of the door 3, and are fixedly connected to the door 3 as a single unit. Moving components 5 are respectively provided at both ends of the mounting seats 4. Here, we only take the connection between the mounting seat 4 and the first guide rail 1.1 as an example; the rest is the same. Specifically, a mounting hole 4.1 is provided at the end of the mounting seat 4. The moving component 5 includes a guide sleeve 5.1, and a mounting shaft 5.3 is provided at the top of the guide sleeve 5.1. The mounting shaft 5.3 is fixedly connected to the guide sleeve 5.1, and is rotatably connected to the mounting hole 4.1 of the mounting seat 4 via two bearings 5.4. The guide sleeve 5.1 is slidably connected to the first guide rail 1.1 via a linear bearing 5.5. The cross-section of the first guide rail 1.1 can be circular or square, with various design options.
[0031] After the hatch 3 is installed with the first guide rail assembly 1 and the second guide rail assembly 2, the top two ends of the hatch 3 are slidably connected to the third guide rail 2.1 and the fourth guide rail 2.2 respectively, and the bottom two ends of the hatch 3 are slidably connected to the first guide rail 1.1 and the second guide rail 1.2 respectively. When the hatch 3 is pushed to move, the bottom two ends of the hatch 3 slide along the first guide rail 1.1 and the second guide rail 1.2 respectively. Since the first guide rail 1.1 and the second guide rail 1.2 are arranged at right angles and the two ends of the first guide rail 1.1 and the second guide rail 1.2 are close to each other, and in the moving assembly 5, the guide sleeve 5.1 and the mounting seat 4 on the hatch 3 form a rotatable connection, the hatch 3 will rotate simultaneously when sliding in the first guide rail assembly 1 and the second guide rail assembly 2; similarly, the movement of the top of the hatch 3 with the third guide rail 2.1 and the fourth guide rail 2.2 is also the same.
[0032] Specifically, when the hatch 3 is closed, one bottom end of the hatch 3 is located on the first guide rail 1.1 away from the second guide rail 1.2, and the other bottom end of the hatch 3 is located on the second guide rail 1.2 close to the first guide rail 1.1. As the hatch 3 gradually opens, the bottom end of the hatch 3 located on the first guide rail 1.1 away from the second guide rail 1.2 gradually moves towards the first guide rail 1.1 and closer to the second guide rail 1.2, while the bottom end of the hatch 3 located on the second guide rail 1.2 close to the first guide rail 1.1 gradually moves towards the second guide rail 1.2 and away from the first guide rail 1.1. After the hatch 3 is fully open, one bottom end of the hatch 3 is located on the first guide rail 1.1 and closer to the second guide rail 1.2, and the other bottom end of the hatch 3 is located on the second guide rail 1.2 and away from the first guide rail 1.1. That is, the hatch 3 has moved from the door frame position of the hyperbaric oxygen chamber to a side position of the hyperbaric oxygen chamber. When the hatch changes from the open state to the closed state, the components move in the opposite direction. Similarly, the movement of the hatch 3 on the third guide rail 2.1 and the fourth guide rail 2.2 is the same as described above.
[0033] A limiting component 6 is also provided on the guide rail of the first guide rail assembly 1 or the second guide rail assembly 2. Specifically, in this embodiment, mounting grooves are provided on the circumferential surface of the end of the second guide rail 1.2 and the corresponding circumferential surface of the fourth guide rail 2.2. An elastic bead 6.1 is provided in the mounting groove. The elastic bead 6.1 can extend and retract vertically within the mounting groove. When the guide sleeve 5.1 slides to the position of the elastic bead 6.1, it presses the elastic bead into the mounting groove. When the guide sleeve 5.1 is outside the mounting groove, the elastic bead 6.1 pops out again. In this way, the elastic bead 6.1 can play a certain limiting role for the hatch 3 in the closed or open state, preventing the hatch 3 from moving when open. Similarly, a limiting mounting seat 6.2 is also provided on all guide rails. The limiting mounting seat 6.2 is arranged at the very end of the guide rail and is used to install and position the guide rail inside the hyperbaric oxygen chamber. At this time, the limiting mounting seat 6.2 not only plays a role in fixing the guide rail, but also prevents the guide sleeve 5.1 from detaching from the guide rail, thus playing a limiting role.
[0034] To facilitate the opening of the hatch 3 by staff from the inside or outside, handles 3.1 are provided on both the inside and outside of the hatch 3. The handles 3.1 are elongated in shape, which makes it easier for staff to use and apply force, thus improving the convenience of opening or closing the hatch 3.
[0035] like Figure 4 The hyperbaric oxygen chamber shown includes the aforementioned hyperbaric oxygen chamber door structure. The hyperbaric oxygen chamber is generally rectangular in shape, with a door frame 7 on the front side. A first guide rail assembly 1 is installed at the bottom of the door frame 7 and located inside the hyperbaric oxygen chamber, and a second guide rail assembly 2 is installed at the top of the door frame 7 and located inside the hyperbaric oxygen chamber. A sealing strip 8 is also provided between the door 3 and the door frame 7 to ensure a sealing effect inside the hyperbaric oxygen chamber.
[0036] The hyperbaric oxygen chamber in this design can be opened or closed by moving laterally and rotating. This way, the door 3 will not occupy too much space inside the hyperbaric oxygen chamber during movement, thus reducing the floor area of the hyperbaric oxygen chamber, and it will not affect the entry and exit of staff.
[0037] Example 2: Figures 5 to 7 The diagram shows a hyperbaric oxygen chamber door structure, including a door 3, a first guide rail assembly 1, and a second guide rail assembly 2. The bottom and top of the door 3 are slidably connected to the first guide rail assembly 1 and the second guide rail assembly 2, respectively. The first guide rail assembly 1 is arranged horizontally at the bottom of the door 3, and the second guide rail assembly 2 is arranged horizontally at the top of the door 3. The first guide rail assembly 1 includes a first guide rail 1.1 and a second guide rail 1.2, which are arranged at right angles. Movable components 6 are provided at the bottom and top of the door 3, respectively, and are slidably connected to the first guide rail assembly 1 and the second guide rail assembly 2, thereby allowing the door 3 to move along the guide rails and realize the opening and closing of the door.
[0038] Specifically, such as Figure 1 As shown, the first guide rail assembly 1 is arranged at the bottom of the hatch 3, and the second guide rail assembly 2 is arranged at the top of the hatch 3, both of which are located inside the high-pressure chamber. Specifically, in the first guide rail assembly 1, the first guide rail 1.1 is positioned when the hatch 3 is closed (at the hatch frame opening), and the second guide rail 1.2 is positioned when the hatch 3 is open (on the inner side of the high-pressure chamber). The second guide rail assembly 2 includes a third guide rail 2.1 and a fourth guide rail 2.2. The third guide rail 2.1 corresponds to the position of the first guide rail 1.1 and is located at the top of the hatch 3, and the fourth guide rail 2.2 corresponds to the position of the second guide rail 1.2 and is also located at the top of the hatch 3.
[0039] It should be noted that in the second guide rail assembly 2, only the third guide rail 2.1 can be used. When the hatch 3 is connected to the first guide rail assembly 1 and the second guide rail assembly 2, the two bottom ends of the hatch 3 are slidably connected to the first guide rail 1.1 and the second guide rail 1.2 respectively. Under the action of gravity, the bottom of the hatch 3 forms stable connection points with the first guide rail 1.1 and the second guide rail 1.2 respectively. The top end of the hatch 3 is slidably connected to the third guide rail 2.1. At this time, the hatch 3 has three movement points, which can ensure the stable movement of the hatch 3. In this scheme, the third guide rail 2.1 can correspond to the position of the first guide rail 1.1 or the second guide rail 1.2. In this embodiment, only the second guide rail assembly 2 including the third guide rail 2.1 and the fourth guide rail 2.2 is used as an example for explanation.
[0040] The first guide rail 1.1 and the second guide rail 1.2 are both arc-shaped guide rails, as are the third guide rail 2.1 and the fourth guide rail 2.2. This design is suitable for hyperbaric oxygen chambers that are cylindrical in shape. In this case, the first guide rail 1.1 and the second guide rail 1.2 are arranged at an angle, and the third guide rail 2.1 and the fourth guide rail 2.2 are arranged at an angle. The specific angle can be designed according to the curvature of the wall of the hyperbaric oxygen chamber.
[0041] Furthermore, the hyperbaric oxygen chamber door 3 is an integral curved door (fitting the shape of the cylindrical hyperbaric oxygen chamber), enabling it to withstand the high-pressure environment better; mounting seats 4 are respectively provided at the top and bottom of the door 3, and the mounting seats 4 are fixedly connected to the door 3 as one unit; movable components 5 are respectively provided at both ends of the mounting seats 4. This description focuses on the connection between the mounting base 4 and the first guide rail 1.1, with the rest being the same. Specifically, the mounting base 4 has a mounting hole 4.1 at its end. The moving component 5 includes a roller 5.2, which is rotatably connected to a connecting seat 5.6. The bottom of the connecting seat 5.6 has a U-shaped groove for rotatably connecting the roller 5.2. The top of the connecting seat 5.6 has a mounting shaft 5.3, which is fixedly connected to the connecting seat 5.6. The mounting shaft 5.3 is rotatably connected to the mounting hole 4.1 of the mounting base 4 via two bearings 5.4. The roller 5.2 has a groove structure in the circumferential direction and is engaged and rolled onto the first guide rail 1.1. The cross-section of the first guide rail 1.1 can be circular or square, and various design options are available.
[0042] After the hatch 3 is installed with the first guide rail assembly 1 and the second guide rail assembly 2, the top two ends of the hatch 3 are slidably connected to the third guide rail 2.1 and the fourth guide rail 2.2 respectively, and the bottom two ends of the hatch 3 are slidably connected to the first guide rail 1.1 and the second guide rail 1.2 respectively. When the hatch 3 is pushed to move, the bottom two ends of the hatch 3 slide along the first guide rail 1.1 and the second guide rail 1.2 respectively. Since the first guide rail 1.1 and the second guide rail 1.2 are arranged at an angle and the two ends of the first guide rail 1.1 and the second guide rail 1.2 are close to each other, and in the moving assembly 5, the connecting seat 5.6 and the mounting seat 4 on the hatch 3 form a rotational connection, the hatch 3 will rotate simultaneously when sliding in the first guide rail assembly 1 and the second guide rail assembly 2; similarly, the movement of the top of the hatch 3 with the third guide rail 2.1 and the fourth guide rail 2.2 is also the same.
[0043] Specifically, when the hatch 3 is closed, one bottom end of the hatch 3 is located on the first guide rail 1.1 away from the second guide rail 1.2, and the other bottom end of the hatch 3 is located on the second guide rail 1.2 close to the first guide rail 1.1. As the hatch 3 gradually opens, the bottom end of the hatch 3 located on the first guide rail 1.1 away from the second guide rail 1.2 gradually moves towards the first guide rail 1.1 and closer to the second guide rail 1.2, while the bottom end of the hatch 3 located on the second guide rail 1.2 close to the first guide rail 1.1 gradually moves towards the second guide rail 1.2 and away from the first guide rail 1.1. After the hatch 3 is fully open, one bottom end of the hatch 3 is located on the first guide rail 1.1 and closer to the second guide rail 1.2, and the other bottom end of the hatch 3 is located on the second guide rail 1.2 and away from the first guide rail 1.1. That is, the hatch 3 has moved from the door frame position of the hyperbaric oxygen chamber to a side position of the hyperbaric oxygen chamber. When the hatch changes from the open state to the closed state, the components move in the opposite direction. Similarly, the movement of the hatch 3 on the third guide rail 2.1 and the fourth guide rail 2.2 is the same as described above.
[0044] A limiting component 6 is also provided on the guide rail of the first guide rail assembly 1 or the second guide rail assembly 2. Specifically, in this embodiment, an installation groove is provided on the circumferential surface of the end of the second guide rail 1.2 and the corresponding circumferential surface of the fourth guide rail 2.2. An elastic ball 6.1 is provided in the installation groove. The elastic ball 6.1 can extend and retract vertically in the installation groove. When the roller 5.2 slides to the position of the elastic ball 6.1, it will press the elastic ball into the installation groove. When the roller 5.2 is outside the installation groove, the elastic ball 6.1 will pop out again. In this way, the elastic ball 6.1 can play a certain limiting role on the hatch 3 in the closed or open state, preventing the hatch 3 from moving in the open state. Similarly, limit mounting seats 6.2 are also provided on all guide rails. The limit mounting seats 6.2 are arranged at the far end of the guide rails and are used to install and position the guide rails inside the hyperbaric oxygen chamber. Specifically, the limit mounting seats 6.2 are screw structures. One end of the screw connects the guide rail and the hyperbaric oxygen chamber by thread to form a fixation. The other end of the screw is provided with a nut 6.21, which is located on the rolling path of the roller. At this time, the limit mounting seats 6.2 can not only fix the guide rails, but also prevent the rollers 5.2 from dislodging from the guide rails, thus playing a limiting role.
[0045] To facilitate the opening of the hatch 3 by staff from the inside or outside, handles 3.1 are provided on both the inside and outside of the hatch 3. The handles 3.1 are elongated in shape, which makes it easier for staff to use and apply force, thus improving the convenience of opening or closing the hatch 3.
[0046] like Figure 8 The hyperbaric oxygen chamber shown includes the aforementioned hyperbaric oxygen chamber door structure. The hyperbaric oxygen chamber is cylindrical in shape, with a door frame 7 on the front side. A first guide rail assembly 1 is installed at the bottom of the door frame 7 and located inside the hyperbaric oxygen chamber, and a second guide rail assembly 2 is installed at the top of the door frame 7 and located inside the hyperbaric oxygen chamber. A sealing strip 8 is also provided between the door 3 and the door frame 7 to ensure a sealing effect inside the hyperbaric oxygen chamber.
[0047] The hyperbaric oxygen chamber in this design can be opened or closed by circumferential movement and rotation. This way, the door 3 will not occupy too much space inside the hyperbaric oxygen chamber during movement, reducing the floor area of the hyperbaric oxygen chamber, nor will it affect the entry and exit of staff.
