Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oxygen chambers, in particular to an oxygen chamber door. Background Art
[0002] An oxygen chamber is a sealed, manned pressure chamber. This sealed environment maintains a constant pressure higher than the external atmospheric pressure. Oxygen is pumped in to ensure the atmosphere meets the patient's needs, achieving a therapeutic effect. Because it's a sealed environment, the sealing of the chamber door is crucial.
[0003] Announcement No. CN117919039B discloses a sealing structure based on a civilian hyperbaric oxygen chamber and its use method. The present invention includes an oxygen chamber shell, a door frame opened on the oxygen chamber shell, and a seat placed inside the oxygen chamber shell. It also includes: a door panel hinged on the door frame of the oxygen chamber shell, and the door panel is located on the inner side of the door frame; an airbag embedded in the door frame, and the door panel abuts the airbag. The present invention enables the hyperbaric oxygen chamber to be effectively sealed by adjusting the setting of the component. During the operation of the oxygen supply component, the airbag can be expanded. If there is a gap between the door panel and the airbag, the expansion of the airbag can also straighten the gap, so that the abutment between the door panel and the airbag is more complete, thereby making the sealing of the hyperbaric oxygen chamber more thorough, which is conducive to avoiding the situation where the sealing is not thorough due to the door panel not being fully abutted with the airbag.
[0004] The hatch door seal mentioned in the invention uses the airbag to inflate, so that the airbag and the hatch door are in close contact. At the same time, after the pressure cabin reaches a positive pressure state, the pressure inside the door is always higher than the pressure outside, squeezing the airbag to form a sealing condition; the airbag itself does not have an extension effect. After inflation, the state it reaches is certain, and the door will push inward to form a gap. The sealing effect is poor in the initial pressurization. Only when the cabin is pressurized and the positive pressure condition is formed can the sealing effect be achieved. On the other hand, the use of the airbag in the patent requires the use of an I-shaped plate (the patent Figure 3 ), the I-shaped plate is an I-shaped structure, which will squeeze the gas into the airbag when the oxygen supply component is working. This requires considering issues such as the sealing of the I-shaped structure and its active cavity. At the same time, the sealing and wear of the airbag itself also need to be paid attention to, which increases the design, manufacturing and subsequent maintenance costs.
[0005] Based on this, an oxygen chamber door is now provided to eliminate the disadvantages of the existing devices. Utility Model Content
[0006] The purpose of the utility model is to provide an oxygen cabin door to solve the problems in the background technology.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] An oxygen cabin door comprises a cabin door, wherein the cabin door is slidingly arranged on one side of a cabin body;
[0009] The hatch is slidably connected to one side of the cabin body through a slide rail assembly and a slide plate assembly. The contact part between the hatch and the cabin body adopts a wedge-shaped surface design. Sealing grooves are opened around the front of the hatch. A sealing strip is fixedly connected to the inside of the cabin body. The sealing strip is limitedly connected to the sealing groove. A telescopic assembly is provided on one side of the cabin body.

[0019] 1. The present invention adopts a wedge-shaped surface design at the contact portion between the hatch and the cabin body by setting a slide rail assembly, etc. When the telescopic mechanism pushes the hatch door to fully fit with the cabin body, due to the relationship of the wedge-shaped surface, the lateral movement direction along the guide rail will be converted into a movement trend perpendicular to the wedge-shaped surface. Due to the limitation of the guide rail, it can only move along the guide rail, thereby squeezing the wedge-shaped surface to form a seal. After full fit, the sealing strip is tightly attached to the two contact surfaces to achieve a sealing effect, and the sealing can be completed without requiring a certain pressure to be reached in the cabin.
[0020] 2. The utility model provides a telescopic assembly, in which the setting of the hinged seat ensures that the telescopic mechanism is only subjected to axial force in the telescopic direction without generating bending moment, thereby protecting the service life of the motion mechanism; at the same time, the telescopic mechanism is installed on the side of the cabin door moving direction, which reduces space occupation and improves space utilization.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0027] In one embodiment, Figure 1-Figure 4 As shown, an oxygen cabin door includes a door 2, which is slidably arranged on one side of a cabin body 1;
[0028] The hatch 2 is slidably connected to one side of the cabin body 1 by means of a slide rail assembly and a slide plate assembly. The contact portion between the hatch 2 and the cabin body 1 is designed with a wedge-shaped surface. A sealing groove 14 is provided around the front of the hatch 2. A sealing strip 11 is fixedly connected to the inside of the cabin body 1. The sealing strip 11 is positionally connected to the sealing groove 14. A telescopic assembly is provided on one side of the cabin body 1.
[0029] In this embodiment, a position sensor is provided at the position where the door 2 and the cabin body 1 meet. The position sensor detects whether the door is in contact. The telescopic assembly pushes the door 2 along the guide rail. When it reaches the wedge-shaped surface area, the guide rail limit makes the cabin body 1 and the door 2 closely fit together and squeezes the sealing strip 11 to form a seal.
[0030] In one embodiment, Figure 2 As shown, the telescopic assembly includes an electric telescopic rod 3, one end of the electric telescopic rod 3 is hinged with a cabin hinge seat 5, and the cabin hinge seat 5 is fixedly connected to one side of the adjacent cabin 1. The other end of the electric telescopic rod 3 is hinged with a cabin door hinge seat 4, and the cabin door hinge seat 4 is fixedly connected to one side of the adjacent cabin door 2. Both the cabin door hinge seat 4 and the cabin hinge seat 5 are of hinged design, which ensures that the telescopic mechanism is only subjected to axial force in the telescopic direction and no bending moment is generated, thereby protecting the service life of the motion mechanism.
[0031] In one embodiment, Figure 3 As shown, the slide rail assembly includes an upper fixed slide rail 8, one end of which is fixedly connected to the upper end of the inner side of the cabin body 1, and a lower fixed slide rail 9 is symmetrically arranged below the upper fixed slide rail 8. One end of the lower fixed slide rail 9 is fixedly connected to the lower end of the inner side of the cabin body 1, and a slide groove 10 is provided on the same side end of the lower fixed slide rail 9 and the upper fixed slide rail 8.
[0032] In one embodiment, Figure 4 As shown, the slide assembly includes an upper fixed slide 13, which is fixedly connected to one side of the upper end of the cabin door 2, and a lower fixed slide 12 is fixedly connected to one side of the lower end of the cabin door 2. The lower fixed slide 12 and the upper fixed slide 13 are symmetrically arranged and are both rotatably connected to a number of pulleys 15. The lower fixed slide 12 and the upper fixed slide 13 can be disassembled and installed, which is convenient for maintenance and servicing.
[0033] In one embodiment, Figure 2 As shown, the pulleys 15 are respectively slidably arranged on the inner side of the corresponding slide grooves 10 to ensure smooth sliding of the cabin door 2. At the same time, a force sensor is arranged in the slide groove 10 to detect the reverse force applied to the guide rail.
[0034] In one embodiment, Figure 2 As shown, a plurality of handles 6 are fixedly connected in an array on one side of the hatch 2 .
[0035] In one embodiment, Figure 2 As shown, an exhaust valve 7 is provided on one side of the hatch 2, which is used to allow the high-pressure gas in the cabin to diffuse to the atmospheric environment outside the cabin during the decompression and opening of the door. When the air inside and outside the cabin is consistent, the hatch 2 will open better.
[0036] In one embodiment, Figure 2 As shown, an airtightness sensor 16 is fixedly connected to the inner side of the cabin 1 to detect the airtightness inside the cabin 1.
[0037] The above embodiment discloses an oxygen cabin door. First, the pushing and retracting movements of the electric telescopic rod 3 are integrated into the button to form a one-touch door opening and closing design; after the one-touch door 2 is opened, the electric telescopic rod 3 pushes the cabin body 1 to move along the upper fixed slide rail 8 and the lower fixed slide rail 9. After reaching the wedge surface area, due to the limit of the upper fixed slide rail 8 and the lower fixed slide rail 9, the cabin door 2 is tightly fitted to the cabin body 1 and the sealing strip is squeezed to form a seal; when the wedge surface is tightly fitted to a certain extent, the position sensor detects whether the cabin door is fitted, and the force sensor detects the reverse force applied to the guide rail. The two sets of sensor parameters are used to determine whether the seal is intact, and the signal is transmitted to the telescopic mechanism to maintain its state to achieve a sealing effect.
[0038] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
