How to effectively protect the safety of personnel in emergencies has become an important research topic. As an important part of civil air defense engineering, civil air defense doors undertake the important task of ensuring the safe evacuation of personnel in basements, air-raid shelters, etc. Therefore, designing a civil air defense door that can effectively resist external impacts, especially in extreme situations such as explosions, which can maintain stability and integrity, is of great significance to improving the safety performance of civil air defense engineering.

[0003] Deficiencies of existing technology:

[0004] At present, most civil air defense doors on the market adopt traditional structural designs. Although these civil air defense doors can withstand external impacts to a certain extent and protect the lives and property of the people, when encountering the violent shock wave of the explosion or the impact of shrapnel, the door body is prone to deformation or damage, especially the locking mechanism and edge parts of the door. Once the door body is deformed or damaged, it will seriously affect the normal opening of the door body, making it difficult for people inside to evacuate quickly in an emergency or after the explosion. In addition, due to the large weight and volume of the main body of the civil air defense door, once the door body is damaged, the cost of repairing or replacing is relatively high, and the operation is relatively difficult, so it is difficult to meet the actual use needs of the current civil air defense doors.

[0032] See also Figure 1-5 As shown, the utility model provides a technical solution for an impact-resistant explosion-proof civil air defense door: an impact-resistant explosion-proof civil air defense door, comprising a door cover 1, a main door body 2 is symmetrically rotatably installed on the inner side of the door cover 1, a buffer component 3 is installed on one side of the main door body 2, and a spare escape component 4 is installed on the other side of the main door body 2; the buffer component 3 includes a buffer groove 301, a positioning hole 303, a positioning screw 305 and a buffer spring 306, the buffer groove 301 is opened on the outer side of the main door body 2, a buffer plate 302 is movably installed in the buffer groove 301, and the positioning hole 303 is opened. A positioning sleeve 304 is provided on the buffer plate 302 and is slidably connected in the positioning hole 303. The buffer plate 302 is installed on the positioning sleeve 304. When impacted, the buffer plate 302 slides on the positioning sleeve 304 for buffering. The positioning screw 305 passes through the hole on the main door body 2 and is threadedly connected to one end of the positioning sleeve 304. The positioning screw 305 is used to fix the positioning sleeve 304 on one side of the main door body 2. The buffer spring 306 is sleeved on the outside of the positioning sleeve 304. The buffer spring 306 is located between the main door body 2 and the buffer plate 302. When an explosion occurs or the front of the civil air defense door is subjected to a severe impact, the buffer plate 302 will first be impacted by shrapnel and shock waves. The impacted buffer plate 302 will overcome the elastic force of the buffer spring 306 and the friction force and move backward along the positioning sleeve 304. The positioning sleeve 304 is ejected from the front end of the positioning hole 303. Through the buffer assembly 3, the buffer plate 302 cooperates with the buffer spring 306 to bear the main impact to be suffered by the civil air defense door from the front, thereby reducing the damage to the main door body 2. The buffer plate 302 is installed in the buffer groove 301 on the outside of the main door body 2. Even if the buffer plate 302 is damaged, the opening function of the main door body 2 can be guaranteed, thereby improving the overall impact resistance of the civil air defense door. In addition, the later repair work focuses on repairing the buffer plate 302, which is more conducive to operation and has lower maintenance costs.

[0033] The spare escape assembly 4 includes an escape door 401 and a push rod 402. The escape door 401 is rotatably connected to the passage on the main door body 2. The push rod 402 is threadedly connected to the threaded hole on the main door body 2. One end of the push rod 402 is installed with a hexagonal head 403. If the main door body 2 is damaged and difficult to open normally due to a high-intensity impact, the escape door 401 can be used for escape. First, all the positioning screws 305 are unscrewed, and then the escape door 401 is opened. Then, the hexagonal head 403 is fixed by a wrench and rotated. The hexagonal head 403 drives the push rod 402 to rotate, thereby pushing the buffer plate 302 out of the buffer groove 301. At this time, the personnel inside the civil air defense door can escape to the outside through the escape door 401. Through the spare escape assembly 4, a spare channel is reserved. Even if the main door body 2 is damaged and cannot be opened normally due to a high-intensity impact, the internal personnel can be guaranteed to evacuate in time later, which further improves the safety and practicality of the door body.

[0034] A plastic baffle 5 is installed on one side of the positioning hole 303. The plastic baffle 5 can prevent the positioning sleeve 304 from rusting and can also be pushed out in time by the positioning sleeve 304 when an impact occurs, without affecting the buffering.

[0035] A dustproof sealing strip 6 is installed on the outer side of the buffer plate 302. Since there is a certain gap between the buffer plate 302 and the buffer groove 301, the sealing strip 6 can prevent dust and water vapor from entering and accelerating the aging of the civil air defense door.

[0036] The escape door 401 is rotatably connected to the inner side wall of the main door body 2 by installing heavy-duty hinges. A latch 7 is installed on one side of the escape door 401. The installation of the escape door 401 is relatively simple. It is positioned by the latch 7 and rotated by the heavy-duty hinges, which is easy to operate.

[0037] The length of the push rod 402 is greater than the overall thickness of the main door body 2 , and after the push rod 402 completely enters the main door body 2 , it can be ensured that the other end of the push rod 402 completely pushes the buffer plate 302 out of the buffer groove 301 .

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
