[0039] A type of air-raid shelter door with movable doors and windows includes a door frame 100, a large door leaf 110, and a small door leaf 140.

[0040] The main door 110 is mounted on the door frame 100. The main door 110 has an installation opening 120 and an observation window 130. Specifically, the installation opening 120 is located near the bottom of the main door 110. A smaller door 140 is hinged to the installation opening 120 on one side, and a door lock 150 is installed on the other side of the installation opening 120. The main door 110 has the installation opening 120, and the smaller door 140 is installed within it. It can be locked when not in use. When a small number of people need to enter or exit, the smaller door 140 can be opened for entry and exit. The smaller door 140 is lightweight and easy to open and close, reducing the time spent opening and closing the main door 110. Furthermore, observation can be made through the observation window 130 to observe the situation inside and outside the air-raid shelter. If observation is not desired, it can be blocked on one side. Therefore, this air-raid shelter door with movable doors and windows allows for convenient temporary entry and exit of a small number of people and facilitates observation of both sides of the air-raid shelter door.

[0041] Specifically, both the installation opening 120 and the small door leaf 140 are rectangular in shape. The rectangular shape of the installation opening 120 and the small door leaf 140 facilitates the installation of hinges and door locks 150, and also facilitates the entry and exit of people. The area of ​​the installation opening 120 does not need to be too large, so as to minimize the impact on the structure of the main door leaf 110.

[0042] like Figure 3 As shown, the small door 140 opens inwards towards the inside of the air-raid shelter door. An opening 120 is located on both sides of the inner side of the door, with L-shaped hooks 160 at the same height. The L-shaped hooks 160 are used to horizontally place the square steel pipe 170. The L-shaped hooks 160 allow the square steel pipe 170 to be used to secure the small door 140 in an emergency, preventing it from opening and providing protection. Normally, they can be left unused and do not affect the opening of the small door 140.

[0043] In addition, such as Figure 1 and Figure 2 As shown, door handles 180 are provided on both the front and rear sides of the small door leaf 140. The door handles 180 facilitate opening and closing the small door leaf 140 from both sides. Furthermore, a sealing strip 190 is provided inside the installation opening 120. The sealing strip 190 serves a sealing function, which is beneficial for sound insulation.

[0044] It's worth mentioning that the small door panel 140 is made of structural steel. Using structural steel can meet basic protection requirements without being too heavy.

[0045] like Figure 1 As shown, the observation window 130 is circular and is located on one side next to the installation opening 120. The circular shape of the observation window 130 means it doesn't need to be too large, and its location next to the installation opening 120 facilitates observation. Specifically, bulletproof glass 200 is installed on the observation window 130. The use of bulletproof glass 200 ensures that the observation window 130 has sufficient protective performance to prevent it from being opened by unauthorized personnel. In addition, a privacy cover 210 is also provided on the inside of the observation window 130, located on the inside of the air-raid shelter door. The privacy cover 210 allows the observation window 130 to be selectively covered when necessary. It should be noted that the edge of the privacy cover 210 has magnets for attaching to the door leaf 110 to close the observation window 130. This design makes the privacy cover 210 flexible in use and convenient to install and remove.
