[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] To address the problems existing in the prior art, this embodiment provides the following technical solution: a civil defense door with an early warning function, comprising a door frame 1 and a civil defense door body 2, wherein a convenient locking mechanism 4 is located inside the right side of the civil defense door body 2, facilitating the quick opening and closing of the civil defense door and reducing the manual labor required during operation; simultaneously, an early warning mechanism 3 is provided, which can monitor harmful gases in real time, and can trigger an alarm in a timely manner once harmful gases are detected to exceed the standard.

[0030] like Figure 2 , Figure 3 and Figure 4As shown, the air-raid shelter door body 2 is installed through an internal hinge in the door frame 1. A threaded rod 42 is threadedly installed on the right side of the inside of the air-raid shelter door body 2. A handle 41 is fixedly installed on the outside of the threaded rod 42. When the air-raid shelter door body 2 needs to be opened, the handle 41 can be gripped and rotated to the right, causing the threaded rod 42 to rotate inside the air-raid shelter door body 2. This loosens the connection between the threaded rod 42 and the threaded rod 42. A gear 43 is installed on the rear outside of the handle 41. The gear 43 rotates together with the threaded rod 42, which pushes the gear rack 44 meshing on both sides of the outside to move outward. The rack 44 is slidably connected to the front side of the rack 44 by a limiting block 47. The limiting block 47 can limit the movement of the rack 44. The meshing rack 44 on both sides of the gear 43 will move in opposite directions. The upper and lower ends of the rack 44 are equipped with locking rods 45. The inner side of the locking rods 45 is engaged with the locking block 46 installed at the rear right side of the door frame 1. That is, when the rack 44 moves, it will drive the locking rods 45 to move together. The locking rods 45 will disengage from the locking block 46. At this time, the body of the air defense door 2 can be pushed to the rear, so that the body of the air defense door 2 can be rotated and opened.

[0031] When it is necessary to close the blast door body 2, rotate the blast door body 2 so that it is located inside the door frame 1, and then hold the handle 41 and rotate it to the left so that the threaded rod 42 is threadedly connected to the inside of the blast door body 2. At this time, the gear 43 installed on the outside of the rear side of the threaded rod 42 will pull the meshing rack 44 to move inward. That is, the locking rods 45 installed at both ends of the rack 44 will move inward and engage with the locking block 46. At this time, the door frame 1 and the blast door body 2 have completed the quick closing and locking.

[0032] like Figure 1 and Figure 7 As shown, an audible and visual alarm 32 and a controller 33 are installed on the upper front side of the interior of the air-raid shelter door body 2. The controller 33 is located to the right of the audible and visual alarm 32. At the same time, a filter cover 31 is set on the outside of the audible and visual alarm 32 and the controller 33. The filter cover 31 is fixed to the air-raid shelter door body 2 by bolts. When the concentration of harmful gas reaches a preset threshold, the audible and visual alarm 32 will convert the signal into an electrical signal to trigger the alarm. At the same time, the audible and visual alarm 32 will transmit the signal to the controller 33 connected by wires on the right. In addition, the controller 33 and the air pump 35 are remotely controlled by wireless communication technology to control the solenoid valve switch. That is, when the controller 33 receives the signal, the air pump 35 will open and inflate the air-filled sealing ring 34. The air-filled sealing ring 34 is set around the gap where the door frame 1 and the air-raid shelter door body 2 are joined, which can fill the gap where the door frame 1 and the air-raid shelter door body 2 are joined, which can strengthen the sealing of the connection between the door frame 1 and the air-raid shelter door body 2 and reduce the flow of harmful gas.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, an escape door body 51 is installed inside the lower part of the door frame 1, which facilitates people's escape. A first fixing block 52 is installed on the lower front side of the escape door body 51. The first fixing block 52 engages with the air defense door body 2. That is, by holding the first fixing block 52 and pushing it upward, the escape door body 51 will slide upward inside the fixing groove 53. A second fixing block 54 is set above the first fixing block 52. The upper end of the second fixing block 54 is fixedly connected to the air defense door body 2. The locking strip 55 inside the second fixing block 54 can be pulled out. After the first fixing block 52 moves upward and engages with the second fixing block 54, the locking strip 55 can be inserted into the interior of the first fixing block 52 and the second fixing block 54 for locking and limiting. At this time, the escape door body 51 is opened, which facilitates people's escape. The opening and locking settings of the escape door mechanism 5 are simple and convenient for quick opening and locking operations.

[0034] The working principle of the air defense door with early warning function is as follows: A convenient locking mechanism 4 is set on the right side of the inside of the air defense door body 2, which facilitates the opening, closing and locking of the air defense door body 2. At the same time, an early warning mechanism 3 is set on the upper front side of the inside of the air defense door body 2, which can monitor harmful gases in real time and issue an alarm in a timely manner. Then, the sealing of the connection between the door frame 1 and the air defense door body 2 can be quickly strengthened.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
