[0002] A protective sealed door is a device used to be installed at the entrances and exits of civil air defense buildings. It includes single-leaf civil air defense doors and double-leaf civil air defense doors. Single-leaf doors are generally used for smaller entrances and exits for personnel, while double-leaf doors are generally used for larger entrances and exits for vehicles. At the same time, protective sealed doors have the functions of blocking shock waves and isolating toxic agents. They can effectively ensure the indoor safety of civil air defense buildings and have been widely used in the field of civil air defense projects.

[0003] For example, a protective closed door installation structure mentioned in patent publication number CN219754350U includes a load-bearing connecting plate adsorbed on the working arm of the civil air defense door installation robot, one end of the load-bearing connecting plate is fixedly connected to a fixed ring, and the outer wall of the fixed ring is processed with four notched grooves. The support connecting rod and the telescopic connecting rod are fixed by bolts to ensure that the total length of the support connecting rod and the telescopic connecting rod remains unchanged, and the angle fixing part and the outer shell of the fixed ring are fixed by bolts to form a fixed relationship, so that the four support connecting rods and the buffer disc cooperate with each other to form a closed structure to clamp the protective closed door, and the buffer disc contacts the elastic telescopic column inside the fixed ring to perform buffering in multiple directions, avoiding collision between the protective closed door and the wall during installation, and improving the safety of the construction operation process.

[0004] Based on the above search, combined with the prior art, it is found that the prior art similar to the above disclosed protective closed door installation structure focuses on the installation improvement between the closed door and the wall. However, due to the heavy weight of the closed door, in order to prevent the closed door from tilting and falling during the installation process, an installer is usually required to hold the closed door alone, which consumes more manpower, and the stability of manual support and fixation is poor, which poses certain safety hazards. Therefore, a protective closed door installation structure is proposed to improve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 In an embodiment of the utility model, a protective sealed door installation structure includes support plates 2 installed on both sides of a sealed door body 1, and adjustable installation components 3 are connected between the upper ends of the support plates 2 and the sealed door body 1 on both sides.

[0030] Among them, the adjustable mounting assembly 3 includes a mounting plate 31 and a mounting block 32, the mounting block 32 is integrated with the mounting plate 31, the mounting plate 31 is detachably fixedly connected to the closed door body 1, and the upper end of the support plate 2 is rotatably connected to the mounting block 32; one of the adjustable mounting assemblies 3 also includes a positioning structure, which is connected between the support plate 2 and the mounting block 32.

[0031] By rotating and installing the support plate 2 on both sides of the closed door body 1 and fixing the rotation angle of the support plate 2 by using the positioning structure, the closed door body 1 can be stably supported when installing the closed door body 1, without manual support, saving manpower, and compared with manual support, the support method of the support plate 2 is more stable and has a higher safety factor; in addition, after the closed door body 1 is installed, the support plate 2 can be naturally hung and stored, such as Figure 1 and Figure 2 In the state shown, when the closed door body 1 is in use, the support plate 2 can provide further protection for the closed door body 1 .

[0032] Among them, the positioning structure includes a threaded rod 35 and an internal threaded sleeve 36. The threaded rod 35 is horizontally and vertically fixedly connected to the side end of the support plate 2. The internal threaded sleeve 36 is threadedly sleeved on the outer side of the threaded rod 35 and abuts against the side end of the mounting block 32 away from the support plate 2.

[0033] The support plate 2 and the closed door body 1 can be relatively fixed by rotating the internal thread sleeve 36 to press against the mounting block 32, which has a simple structure and is easy to operate.

[0034] Among them, an arc block 33 with the same center as the rotation trajectory of the support plate 2 is arranged on the outer side of the mounting block 32. The arc block 33 is integrally arranged with the mounting plate 31, and an arc gap 34 is formed between the arc block 33 and the mounting block 32 to allow the threaded rod 35 to rotate with the support plate 2.

[0035] The arc block 33 can not only cooperate with the installation block 32 to press against the internal threaded sleeve 36, but also serve as a handle. After the closed door body 1 is installed, it is convenient for people to open and close the closed door body 1 when passing through, without installing a separate door handle.

[0036] Among them, a tension spring 37 is fixedly connected between the threaded rod 35 and the mounting plate 31. The tension spring 37 can pull the support plate 2 back toward the side of the closed door body 1, which can effectively prevent the support plate 2 from accidentally opening too much during the process of supporting the closed door body 1, causing the closed door body 1 to fall under force.

[0037] Among them, the support plate 2 is a length-adjustable plate. Specifically, the support plate 2 includes a fixed plate sleeve 21 and a telescopic plate body 22. One end of the fixed plate sleeve 21 is rotatably connected to the mounting block 32, and the other end of the fixed plate sleeve 21 is slidably sleeved on the outer side of the telescopic plate body 22. A locking bolt 23 that abuts against the telescopic plate body 22 is threaded through one side of the fixed plate sleeve 21 close to the telescopic plate body 22.

[0038] The coordinated arrangement of the fixed plate sleeve 21, the telescopic plate body 22 and the locking bolts 23 can effectively adapt to the support requirements of the ground at different heights on both sides of the closed door body 1, and has stronger adaptability.

[0039] In order to facilitate the movement of the closed door body 1, a plurality of balls 4 are movably mounted on the end of the telescopic plate body 22 away from the fixed plate sleeve 21. The arranged balls 4 can act as universal wheels, so as to facilitate and flexibly move the closed door body 1.

[0040] The working principle of the utility model is as follows: the support plates 2 are rotatably installed on both sides of the closed door body 1, and the rotation angle of the support plates 2 is fixed by using a positioning structure, so that the closed door body 1 can be stably supported when the closed door body 1 is installed, without manual support, saving manpower, and compared with manual support, the support method of the support plates 2 is more stable and has a higher safety factor; for the ground at different heights on both sides of the closed door body 1, the fixed plate sleeve 21, the telescopic plate body 22 and the locking bolt 23 can be used to cooperate to achieve stable support for the closed door body 1; in addition, after the closed door body 1 is installed, the support plates 2 can be naturally suspended and stored, such as Figure 1 and Figure 2 In the state shown, when the closed door body 1 is in use, the support plate 2 can provide further protection for the closed door body 1 .

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
