Description

Technical Field

[0001] This utility model relates to the field of civil defense safety technology, and in particular to a movable door cover that can be placed on the outside of a civil defense door. Background Technology

[0002] Civil defense engineering, also known as civil air defense engineering, refers to underground protective buildings constructed separately to ensure the shelter of personnel and materials, civil air defense command, medical rescue, and other needs during wartime, as well as basements built in conjunction with above-ground buildings that can be used for air defense during wartime. Its main purpose is to provide nearby shelter for urban residents during wartime and reduce casualties and losses.

[0003] Civil defense doors are an important component of civil defense projects, mainly used for protection and airtightness. They are specially designed protective devices installed at entrances, connecting points, and ventilation openings of civil defense projects to block shock waves and ensure effective isolation between clean and contaminated areas inside the civil defense project.

[0004] Many stand-alone civil defense projects, high-end residential buildings, and other civil defense basements with aesthetic requirements, as well as urban renewal projects that renovate old civil defense projects for other uses, have requirements for the appearance and color of civil defense doors. They must not only meet the requirements of the protective function, but also coordinate with the overall planning and architectural style in terms of appearance, color and details, and blend with the surrounding environment to reduce visual impact, while improving the overall aesthetics and quality of the basement.

[0005] Therefore, it is necessary to provide a movable door cover that can be placed on the outside of the air-raid shelter door to meet the requirements of changing the appearance and color of the air-raid shelter door without affecting its function. Utility Model Content

[0006] The purpose of this utility model is to provide a movable door cover that can be placed on the outside of a civil defense door, so as to change the appearance, color and other requirements of the civil defense door without affecting its function.

[0024] The specific embodiments of this utility model will now be described in more detail with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0025] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] Civil defense doors are normally open and closed during peacetime to meet the airtightness requirements of civil defense projects. Their protective and airtight functions require them to possess a certain level of strength and stability, and they are generally made of reinforced concrete. Most civil defense doors produced by manufacturers and commonly found on the market are gray or dark green. While these colors can match the atmosphere of underground environments or military facilities, they may appear inconsistent with the overall decor of modern buildings or high-end residential complexes' civil defense basements.

[0027] To address the problems existing in the prior art, this utility model provides a movable, single-piece door cover that can be placed on the outside of a civil defense door.

[0028] A vertically oriented door panel 1;

[0029] At least one baffle is provided; if there are multiple baffles, all of them are disposed on the same side of the door cover panel 1; the baffles are arranged vertically; the door cover panel 1 includes a first side and a second side facing each other, the first side is provided with a baffle and faces the air-raid shelter door, and the second side faces the basement of the air-raid shelter. Preferably, the baffles are perpendicular to the door cover panel 1.

[0030] At least two rollers 5 are provided at the bottom of the door panel 1, with the two rollers 5 respectively located at both ends of the bottom of the door panel 1. Two rollers 5 are also provided at the bottom of each baffle, with the two rollers 5 respectively located at both ends of the bottom of each baffle. Preferably, the rollers 5 are swivel casters.

[0031] Preferably, the top of the door cover panel 1 is higher than the air defense door, and the horizontal length of the baffle is set according to the position and angle of the air defense door to completely cover the air defense door.

[0032] In one embodiment, three baffles are provided: a first baffle 2, a second baffle 3, and a third baffle 4. The height of the door cover panel 1 is 2100mm, and its horizontal length is 2100mm. The height of the first baffle 2 is 2100mm, and its horizontal length is 200mm. The height of the second baffle 3 is 2100mm, and its horizontal length is 500mm. The height of the third baffle 4 is 2100mm, and its horizontal length is 700mm. The thickness of each of the three baffles is 50mm. The third baffle 4 is located at the end away from the rotation center of the air-raid shelter door and is aligned with the end of the door cover panel 1. The distance between the second baffle 3 and the third baffle 4 is 625mm, and the distance between the first baffle 2 and the second baffle 3 is 650mm.

[0033] Preferably, the door panel 1 and the baffle are made of aluminum alloy.

[0034] After the air-raid shelter door is opened to its maximum angle, the door cover is placed outside the door, completely obscuring it and serving an aesthetic purpose. Additionally, baffles of varying lengths are installed behind the door cover panel 1 to ensure the door cover's stability. Rollers 5 are installed below the door cover panel 1 and the baffles, allowing the door cover to be quickly moved to surrounding spaces during wartime, restoring the air-raid shelter door's wartime functionality and achieving rapid peacetime-wartime conversion.
