[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the solution of the present utility model will be further described below. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
[0027] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.
[0028] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0029] The specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Embodiment 1
[0030] Refer to Figure 1 and Figure 2 , this embodiment provides a detachable air lock structure, including a buffer room main body 1, an entrance and exit door 2, a Velcro strip 3 and a second airtight zipper 4.
[0031] Among them, the buffer room main body 1 is used to be installed at the inner front end of the protective outer awning 100, and the buffer room main body 1 has an inflated shape adapted to the inner front end of the protective outer awning 100. When the buffer room main body 1 is in the inflated shape, an opening 11 corresponding to the front zipper door of the protective outer awning 100 is provided on its front end face.
[0032] It should be noted that the buffer room main body 1 needs to be made by sewing with the same main material as the protective outer awning 100.
[0033] It is easily understandable that the overall size of the buffer room can be adjusted by the supporting air ribs 200 to match the defined size of the buffer room.
[0034] Furthermore, when the buffer room main body 1 is in the inflated state, a first pressure relief valve is provided at its rear end face. When inflating, when the air pressure in the working room reaches the target air pressure, the first pressure relief valve opens, and the working room releases pressure into the buffer room. The first pressure relief valve can simplify the inflation step and improve the inflation efficiency.
[0035] Wherein, the access door 2 is connected to the buffer room main body 1 through the first airtight zipper 21, and when the buffer room main body 1 is in the inflated state, the access door 2 is located on the rear end face of the buffer room main body 1.
[0036] Specifically, the first airtight zipper 21 is of a U-shaped structure, and the opening 11 of the U-shaped structure faces left or right. The first airtight zipper 21 of the U-shaped structure facilitates the entry and exit of personnel between the working room and the buffer room.
[0037] Wherein, a plurality of hook-and-loop fasteners 3 are provided and are all fixed on the outer side of the buffer room main body 1. The plurality of hook-and-loop fasteners 3 correspond one by one to the supporting air ribs 200 at the front end inside the protective outer awning 100, and the hook-and-loop fasteners 3 are used to be adhesively fixed on the corresponding supporting air ribs 200 when the buffer room main body 1 is in the inflated state.
[0038] It is easily understandable that since the supporting air ribs 200 are located at the top, side and bottom of the protective outer awning 100, the hook-and-loop fasteners 3 are also correspondingly arranged at the top, side and bottom of the buffer room main body 1. The hook-and-loop fasteners 3 located at the top and side cooperate with the corresponding supporting air ribs 200 to play a role in stretching the buffer room main body 1, and the hook-and-loop fasteners 3 located at the bottom cooperate with the corresponding supporting air ribs 200 to prevent the movement and folding of the materials at the bottom of the buffer room caused by the repeated entry and exit of personnel.
[0039] Specifically, the hook-and-loop fasteners 3 are fixed on the buffer room main body 1 through the connecting strips 5.
[0040] More specifically, the hook-and-loop fasteners 3 are sewn on the connecting strips 5.
[0041] More specifically, the connecting strips 5 are sewn on the buffer room main body 1.
[0042] Wherein, the second airtight zipper 4 is fixed on the edge of the opening 11, and the second airtight zipper 4 is used to be connected to the edge or the outer side of the edge of the front zipper door of the protective outer awning 100 when the buffer room main body 1 is in the inflated state.
[0043] Specifically, the second airtight zipper 4 is a split airtight zipper.
[0044] The detachable air lock structure of this embodiment can not only meet the airtight requirements for isolating the buffer room and the working room from each other, but also realize the independent disassembly and replacement function of the buffer area. Embodiment 2
[0045] The positive pressure protection tent provided by the present utility model includes a protective outer awning 100, a support air rib 200, and the detachable air lock structure of Embodiment 1.
[0046] It should be noted that the above only lists the components related to this solution, but the positive pressure protection tent also needs to be provided with other necessary components, such as an outer ground cloth, an inner ground cloth, a thermal insulation inner tent, etc.
[0047] Specifically, the second airtight zipper 4 is connected to the outer edge of the front zipper door of the protective outer awning 100, and a second pressure relief valve is provided in the area where the buffer room main body 1 is located between the second airtight zipper 4 and the front zipper door of the protective outer awning 100. During inflation, when the air pressure in the buffer room reaches the target air pressure, the second pressure relief valve opens, and the buffer room releases pressure to the outside. The second pressure relief valve can simplify the inflation steps and improve the inflation efficiency. It should be noted that when both the first pressure relief valve and the second pressure relief valve are provided, the target air pressure in the buffer room should be less than the target air pressure in the working room to ensure that both the first pressure relief valve and the second pressure relief valve can work properly.
[0048] The installation steps of the positive pressure protection tent of this embodiment are as follows:
[0049] S1. Lay the outer ground cloth;
[0050] S2. After closing the remaining openings 11 on the protective outer awning except the front zipper door, use a blower to blow air into the protective outer awning;
[0051] S3. Place the support air rib 200 inside the protective outer awning through the front zipper door, unfold and place it in the specified direction, and then use an air pump to inflate the support air rib 200;
[0052] S4. After inflation is completed, fix the support air rib 200 to the protective outer awning and hang the thermal insulation inner tent;
[0053] S5. Install the inner ground cloth;
[0054] S6. Place the buffer room main body 1 inside the tent at the position set as the buffer room, and then fix it to the corresponding support air rib 200 through the velcro strip 3;
[0055] S7. Zip up the split airtight zipper to form an independent sealed area;
[0056] S8. Installation is completed.
[0057] The above are only the specific embodiments of the present utility model, enabling those skilled in the art to understand or implement the present utility model. Although the foregoing embodiments have been described in detail, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
