Description

Technical Field

[0001] This utility model belongs to the field of oxygen chamber technology, specifically relating to an automatic sliding sealing door for an oxygen chamber. Background Technology

[0002] Oxygen chambers are primarily used to treat various diseases, especially those related to hypoxia. By providing a pure oxygen environment at above atmospheric pressure, oxygen chambers help patients accelerate tissue repair and recovery. They increase the pressure of the patient's environment, thus increasing the partial pressure of oxygen inhaled and consequently raising the dissolved oxygen levels in the blood. This helps improve tissue hypoxia, promotes wound healing, reduces inflammation, and has some antibacterial properties.

[0003] Many of the oxygen chamber doors currently used are either hinged or sliding. Since patients frequently enter and exit the oxygen chamber, the doors often fail to close properly after being opened, leaving gaps between the door and the chamber body. This affects the airtightness of the oxygen chamber, causing oxygen leakage and a decrease in oxygen concentration. In addition, the sealing strips on many oxygen chamber doors are prone to damage and aging after repeated squeezing and opening, which also affects the airtightness of the chamber body. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sliding sealing door for an oxygen chamber, which can efficiently seal the gap between the door and the chamber body to prevent oxygen leakage.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] An automatic sliding sealing door for an oxygen chamber includes a chamber body, a door frame fixedly connected to the side wall of the chamber body, a storage groove on the side wall of the door frame, a sliding door slidably connected within the storage groove, a sliding assembly disposed within the storage groove, a sealing gasket fixedly connected to the side of the sliding door, a slot corresponding to the sliding door on the side wall of the door frame, a U-shaped cavity inside the door frame near the slot, and auxiliary sealing assemblies disposed on the three side walls of the cavity near the sliding door.

[0007] The translation component includes a first motor fixedly installed on the side wall of the storage slot. The output shaft of the first motor is fixedly connected to a first screw. The side wall of the sliding door has a screw hole corresponding to the first screw, and the first screw is threadedly connected to the screw hole.

[0008] The sealing assembly includes a threaded sleeve movably connected to the side wall of the cavity near the sliding door. The threaded sleeve extends into a slot and is fixedly connected to a pressure plate. A second screw is threadedly connected to the inner thread of the threaded sleeve. Two drive shafts are symmetrically connected to the left side wall of the cavity. Grooved wheels are fixedly connected to one end of the drive shaft and the second screw. A belt is connected between the two grooved wheels on the same side. A transmission assembly is provided on the left side wall of the cavity.

[0009] The transmission assembly includes a second motor fixedly connected to the side wall of the cavity, a rotating shaft fixedly connected to the output shaft of the second motor, the other end of the rotating shaft fixedly connected to the second screw on the left side, a first bevel gear fixedly connected to the side wall of the rotating shaft, and second bevel gears meshing on the upper and lower sides of the first bevel gear respectively, and the other end of the transmission shaft fixedly connected to the second bevel gear.

[0010] Each pressure plate sidewall is fixedly connected to a limiting rod, and the other end of the limiting rod extends into the cavity.

[0011] The sealing gasket has a hollow structure.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses an automatic sliding sealing door for an oxygen chamber. Through the cooperation of the chamber body, door frame, sliding door, and auxiliary sealing components, after the sliding door is closed, the pressure plate can be used to squeeze the sealing gasket on the side of the sliding door, making the gap between the sliding door and the chamber body smaller than before, ensuring the airtightness of the chamber, preventing oxygen leakage and causing the oxygen concentration to be too low, thereby improving the oxygen utilization rate.

[0020] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-4 As shown, an automatic sliding sealing door for an oxygen chamber includes a chamber body 1. A door frame 2 is fixedly connected to the side wall of the chamber body 1. A storage groove 3 is provided on the side wall of the door frame 2. A sliding door 4 is slidably connected in the storage groove 3. A sliding component is provided in the storage groove 3. A sealing gasket 8 is fixedly connected to the side of the sliding door 4. A slot 5 corresponding to the sliding door 4 is provided on the side wall of the door frame 2. A cavity 9 is provided inside the door frame 2 near the slot 5. The cavity 9 is U-shaped. Auxiliary sealing components are provided on the three side walls of the cavity 9 near the sliding door 4.

[0022] like Figure 2 As shown, the sliding assembly includes a first motor 6 fixedly installed on the side wall of the storage slot 3. The output shaft of the first motor 6 is fixedly connected to a first screw 7. The side wall of the sliding door 4 has a screw hole corresponding to the first screw 7, and the first screw 7 is threadedly connected to the screw hole. The method of driving the sliding door 4 to open and close by setting the first motor 6 and the first screw 7 is existing technology, and its control method and operating principle will not be detailed in this solution.

[0023] like Figure 2 and Figure 3 As shown, the sealing assembly includes a threaded sleeve 10 movably connected to the side wall of the cavity 9 near the sliding door 4. The threaded sleeve 10 extends into the slot 5 and is fixedly connected to a pressure plate 11. A second screw 12 is threadedly connected to the inner side of the threaded sleeve 10. Two drive shafts 15 are symmetrically rotatably connected to the side wall of the cavity 9 near the left side. One end of the drive shaft 15 and the second screw 12 are respectively fixedly connected to a grooved wheel 13. A belt 14 is connected between the two grooved wheels 13 on the same side. A transmission assembly is provided on the left side wall of the cavity 9.

[0024] Specifically, the sliding door 4 and the storage slot 3 are in a tight state. When the sliding door 4 is closed, the sliding door 4 located in the storage slot 3 and the storage slot 3 can be sealed by the sealing strip. The sliding door 4 inserted into the slot 5 can reduce the gap by the pressure of the three pressure plates 11, thus achieving a highly efficient seal.

[0025] like Figure 2 and Figure 4 As shown, the transmission assembly includes a second motor 16 fixedly connected to the side wall of cavity 9. The output shaft of the second motor 16 is fixedly connected to a rotating shaft 17. The other end of the rotating shaft 17 is fixedly connected to a second screw 12 on the left side. A first bevel gear 18 is fixedly connected to the side wall of the rotating shaft 17. Second bevel gears 19 mesh with the upper and lower sides of the first bevel gear 18, respectively. The other end of the transmission shaft 15 is fixedly connected to the second bevel gears 19. The transmission assembly can simultaneously drive the second screws 12 on all three sides to rotate synchronously, thereby achieving the purpose of synchronously compressing the sealing gasket 8. It features fewer driving components, a stable transmission structure, and good sealing performance.

[0026] like Figure 3 As shown, limit rods 20 are fixedly connected to the side walls of the pressure plate 11, and the other end of the limit rods 20 extends into the cavity 9. By setting the limit rods 20, the movement position of the pressure plate 11 can be limited, keeping it in a translational state and avoiding tilting during translation, thus accurately pressing the sealing gasket 8.

[0027] The sealing gasket 8 has a hollow structure. Specifically, because the sealing gasket 8 has a hollow structure, when the pressure plate 11 squeezes the sealing gasket 8, the sides of the sealing gasket 8 will lift up, while the middle position will sink down, increasing the fit between the sealing gasket 8 and the pressure plate 11, thereby achieving the purpose of sealing.

[0028] The working principle of this utility model is as follows: When the sliding door 4 needs to be closed, the first motor 6 is started to drive the first screw 7 to rotate. The first screw 7 drives the sliding door 4 to slide and close through the screw hole, so that the sliding door 4 and the sealing gasket 8 are tightly attached to the slot 5. Then, the second motor 16 is started. The output shaft of the second motor 16 drives the first bevel gear 18 to rotate through the rotating shaft 17. The first bevel gear 18 meshes with the second bevel gear 19 to drive the transmission shaft 15 to rotate. The transmission shaft 15 drives the side grooved wheel 13 to rotate. The side grooved wheel 13 drives the other side grooved wheel 13 to rotate through the belt 14, so that the grooved wheel 13 and the rotating shaft 17 drive the second screw 12 to rotate respectively. The second screw 12 drives the pressure plate 11 to move towards the sealing gasket 8 through the screw sleeve 10, squeezing the sealing gasket 8 and reducing the gap between the sliding door 4 and the door frame 2, ensuring that the cabin 1 is in a high-sealing state and effectively improving its sealing effect.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
