Detailed Embodiments
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.
[0022] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0023] To achieve the above object, an embodiment of the present utility model provides a micro-pressure oxygen-enriched cabin door structure. Referring to Figure 1-6 as shown, it includes a micro-pressure oxygen-enriched cabin door body 1. The micro-pressure oxygen-enriched cabin door body 1 includes a cabin door panel 2, a first cabin door handle 3, a transverse strengthening lock bar 4, and a second cabin door handle 5. A number of through holes 6 are arranged horizontally in the upper-middle part of the cabin door panel 2. A first cabin door handle 3 is provided on one side of the cabin door panel 2, and a transverse strengthening lock bar 4 is provided on the other side of the cabin door panel 2. The transverse strengthening lock bar 4 is fixedly connected to the first cabin door handle 3 through the through holes 6. A square groove 7 for sleeving the transverse strengthening lock bar 4 is provided on one side of the second cabin door handle 5, and the second cabin door handle 5 is fixedly connected to the square groove 7.
[0024] In order for the traditional micro-pressure oxygen-rich cabin not to affect the use of the cabin door during the pressurization process, the designed cabin door is at least the superposition of two cabin doors, or additional pressing blocks are added to enhance the thickness and strength of the cabin door, which undoubtedly increases the overall weight and material cost of the cabin door. In this embodiment, a single cabin door panel 2 is adopted, and after optimizing and improving the traditional door handle, it is supplemented to the cabin door panel 2, which not only solves the problem of the single structural function of the traditional door handle, but also improves the strength of the cabin door panel 2 to withstand the pressure during pressurization, further enhancing the practicality of the entire cabin door panel 2. Specifically, a horizontally laid transverse strengthening lock bar 4 is designed in the width direction in the middle of the cabin door. The length of the transverse strengthening lock bar 4 is less than the width of the cabin door panel 2. Here, it is based on the width that the cabin door panel 2 can be installed and set in, that is to say, as long as it is lower than the width of the cabin door panel 2 and does not affect the use of the cabin door panel 2, in this way, during the pressurization process of the micro-pressure oxygen-rich cabin, the cabin door panel 2 will not have arc deformation, or the arc deformation is very small and can be ignored. The semi-U-shaped first cabin door handle 3 and the second cabin door handle 5 are fixedly connected to the transverse strengthening lock bar 4 at the same position. In addition to being able to further supplement the strength of the cabin door panel 2, it also optimizes and enriches the functional use of the first cabin door handle 3 and the second cabin door handle 5. The structure of the entire micro-pressure oxygen-rich cabin door body 1 is simple, meets the use requirements of a certain strength, and is very easy to install.
[0025] Furthermore, strip-shaped concave grooves 8 are provided both above and below one side edge of the cabin door panel 2. A plurality of mounting holes 9 are provided on the strip-shaped concave grooves 8, and a movable hinge is fixedly connected to the strip-shaped concave grooves 8 through the mounting holes 9. In this way, through the hinge fixed to the strip-shaped concave grooves 8, it can be installed on the specific cabin opening of the micro-pressure oxygen-rich cabin, enabling the cabin door panel 2 to form a movable connection state, and a sealing strip can be arranged at the cabin opening to enhance the sealing performance of the cabin door when it is closed.
[0026] Furthermore, a plurality of blind holes 10 corresponding to the through holes 6 are provided on one side of the first cabin door handle 3, and a plurality of counterbored cup holes 11 corresponding to the through holes 6 are provided on the transverse strengthening lock bar 4. The transverse strengthening lock bar 4 and the first cabin door handle 3 are respectively fastened to the two side surfaces of the cabin door panel 2 by passing a socket head screw through the counterbored cup holes 11 and fasteningly connecting with the blind holes 10, increasing the strength.
[0027] Furthermore, a plurality of through holes 12 are provided at the upper end of the second cabin door handle 5, a plurality of internal threaded holes 13 corresponding to the through holes 12 are provided at the lower end of the second cabin door handle 5, and a plurality of vertical holes 14 corresponding to the through holes 12 are provided through the upper and lower sides of the transverse strengthening lock bar 4. By sequentially passing screws through the through holes 12 and the vertical holes 14 and then fasteningly connecting with the internal threaded holes 13, in this way, there are no hole positions and slot holes, etc. on the front end face of the entire second cabin door handle 5, making the appearance of the second cabin door handle 5 more beautiful and simple, and its connection with the transverse strengthening lock bar 4 has a certain practicality.
[0028] When the micro-pressure oxygen-rich cabin is in use, first close the micro-pressure oxygen-rich cabin door body 1. Pressurize the cabin interior and wait for a few seconds. A certain pressure difference is formed between the inside and outside of the micro-pressure oxygen-rich cabin. The internal pressurization will apply an outward pressing force to the micro-pressure oxygen-rich cabin door body 1, causing the cabin door panel 2 and the sealing strip where its door frame is located to form a mutually pressed and sealed state, achieving the automatic locking of the cabin door panel 2; when the pressure is released, the air pressure inside the cabin is released, and the cabin door panel 2 and the sealing strip will loosen. Under the elastic rebound of the sealing strip, the cabin door panel 2 is in a state of being bounced open, achieving the automatic opening of the cabin door panel 2 and waiting for the next use.
[0029] In summary, the present utility model provides a micro-pressure oxygen-rich cabin door structure. By means of the transverse strengthening lock strip 4, the first cabin door handle 3 and the second cabin door handle 5 in a semi-U-shaped structure are arranged on both sides of the cabin door panel 2. The first cabin door handle 3 and the second cabin door handle 5 are optimized on the cabin door panel 2 to enhance the functional uses of the first cabin door handle 3 and the second cabin door handle 5. The transverse strengthening lock strip 4 is arranged horizontally to strengthen the strength of the cabin door to withstand the pressure difference between the inside and outside of the cabin under high-pressure conditions, ensuring the safety of use.

The protection scope of the present utility model is not limited to the above embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. Those skilled in the art can think of other specific embodiments of the present utility model without creative labor, and all of them will fall within the protection scope of the present utility model.
