[0027] In this embodiment, the wall thickness of the explosion-proof steel cylinder 2 is 10 cm. A buffer block is arranged inside the explosion-proof steel cylinder 2 to prevent personnel from directly colliding with the inner wall of the explosion-proof steel cylinder 2 and being injured by direct contact. At the same time, a climbing ladder is fixedly arranged on the inner wall of the explosion-proof steel cylinder 2, so that personnel can quickly escape from the escape hole 26 at the top of the explosion-proof steel cylinder 2 with the help of the climbing ladder in case of emergencies. In case of emergencies, such as rolling stones on the mountain, the explosion-proof steel cylinder 2 may be knocked down and the door body 4 may be pressed between the explosion-proof steel cylinder 2 and the ground, or the door body 4 may be deformed and unable to be opened due to the blasting power. The explosive bolt 23 is a commercially available part, and the detonating device is arranged on the inner wall of the explosion-proof steel cylinder 2. The working principle is the prior art and will not be repeated here.
[0028] The opening and closing assembly is provided to facilitate the staff to open and close the door body 4, while ensuring the sealing and stability of the door body 4 in the closed state, and preventing the door body 4 from swinging due to the blast shock wave;
[0029] The escape hatch 26 can be used to allow staff to escape safely from the explosion-proof steel cylinder 2 in case of an emergency.
[0030] The explosive bolts 23 are used to fasten the connection between the cover body and the explosion-proof steel cylinder 2, which can prevent daily wind and rain, and can also respond to emergencies. The operator detonates the explosive bolts 23 to make the explosive bolts 23 self-destruct, which can separate the solid cover body from the explosion-proof steel cylinder 2, thereby buying precious time for the staff to escape.
[0031] The observation windows are set up to facilitate the staff to observe the external blasting situation in time.
[0032] The utility model can ensure that personnel can escape quickly when encountering an emergency, buy precious time for escape, and improve safety.

The external handle 8 is located on the outside of the door body 4, and the internal handle 9 is located on the inside of the door body 4.
[0034] In this embodiment, both ends of the telescopic rod 7 are respectively hinged to the sleeve 6 and the door body 4 through disc damping hinges. The disc damping hinges are commercially available and the specific working principle will not be described in detail here.
[0035] By pulling the outer handle 8, the outer handle 8 drives the door body 4, and the door body 4 pulls the telescopic rod 7 to extend. At the same time, the telescopic rod 7 rotates and tilts between the sleeve 6 and the door body 4. At this time, the door body 4 rotates on the bracket 3 to open the door body 4. When the extended length of the telescopic rod 7 is the limit, in order to further increase the opening and closing angle of the door body 4 to facilitate people to enter and exit, the outer handle 8 can be pulled continuously, and the door body 4 drives the sleeve 6 to slide on the guide rod 5 through the telescopic rod 7, so that the door body 4 can continue to rotate on the bracket 3, thereby making the door body 4 reach In the fully open state, it should be noted that the telescopic rod 7 is a gas spring support rod, which can be locked at any extended length, thereby realizing that the door body 4 stops at a certain opening and closing angle, which is convenient for people to enter and exit. When the door body 4 needs to be closed, people only need to pull the inner handle 9 in the explosion-proof steel cylinder 2 to shrink the telescopic rod 7 and tilt it in the reverse direction. The sleeve 6 slides in the reverse direction of the guide rod 5 and resets to realize the closing of the door body 4. Under the limiting action of the telescopic rod 7, the door body 4 is prevented from swinging due to the explosion shock wave, making the door body 4 more stable.

[0039] By rotating the handle, the handle drives the threaded rod 15 to rotate, and the threaded rod 15 rotates on the fixed seat 14. At the same time, the threaded rod 15 is screwed together with the thread of the explosion-proof steel cylinder 2, and the length of the threaded rod 15 extending out of the explosion-proof steel cylinder 2 gradually increases, and drives the fixed seat 14 to move. The connecting plate 13 on the fixed seat 14 rotates on the sleeve 29, and pushes the window guard 11 to rotate on the bracket 10, so as to realize the opening of the window guard 11. In order to further increase the opening angle of the window guard 11, continue to rotate the handle, and the sleeve 29 slides on the guide rod 12 under the push of the threaded rod 15.
