Both the first and second observation holes 11 and 12 communicate with the cavity. The observation component is slidably disposed within the cavity and is adapted to align with the first and second observation holes 11 and 12 for observing external conditions. The support block 30 is disposed on one side of the observation component and connected to it. The support block 30 is slidably disposed within the cavity and is adapted to align with the first and second observation holes 11 and 12 to form support. The drive component is connected to the door body 10, and its power output end is connected to the observation component or the support block 30 to drive the observation component and the support block 30 to slide, aligning with or offset from the first and second observation holes 11 and 12.
[0038] The beneficial effects of the nickel-saving stainless steel air-raid shelter door provided by this utility model are as follows: Compared with the prior art, the nickel-saving stainless steel air-raid shelter door provided by this utility model can, when it is necessary to observe the outside world, drive the observation component and the support block 30 to slide through the drive component, so that the observation component is aligned with the first observation hole 11 and the second observation hole 12 to observe the external environment; when it is not necessary to observe the outside world, the support block 30 is aligned with the first observation hole 11 and the second observation hole 12 to provide support for the door body 10 at this location, so as to ensure the strength of the door body 10 at the first observation hole 11 and the second observation hole 12, and avoid the first observation hole 11 and the second observation hole 12 from significantly reducing the overall strength of the air-raid shelter door.
[0039] like Figure 1 and Figure 2 As shown, in a specific embodiment of the nickel-saving stainless steel air defense door provided in this utility model, the first observation hole 11 and the second observation hole 12 are staggered to disperse the influence on the door body 10 and avoid significantly reducing the strength of the local door body 10.
[0040] Furthermore, such as Figure 1 and Figure 2 As shown, in a specific embodiment of the nickel-saving stainless steel air defense door provided in this utility model, the observation component includes a mounting frame 21 and a periscope 22. The mounting frame 21 is disposed in the receiving cavity and is slidably engaged with the door body 10. The support block 30 is connected to the mounting frame 21. The periscope 22 is connected to the mounting frame 21, and its two ends are respectively adapted to be aligned with the first observation hole 11 and the second observation hole 12.
[0041] Specifically, the lower viewing window of the periscope 22 is aligned with the first observation hole 11 located inside the door 10, and the upper viewing window is aligned with the second observation hole 12 outside the door 10; the periscope 22 uses stainless steel lenses or other unbreakable lenses.
[0042] like Figure 1 and Figure 2 As shown, in a specific embodiment of the nickel-saving stainless steel air defense door provided in this utility model, the observation component further includes a cat's eye lens 23, which is connected to the mounting bracket 21 and aligned with one end suitable for alignment with the second observation hole 12.
[0043] It should be noted that the cat-eye lens 23 in this embodiment is an existing device, aligned with the viewing window on the upper side of the periscope 22, to increase the field of view. The mounting bracket 21 is a sleeve-shaped structure extending along the thickness direction of the door body. Both the periscope 22 and the cat-eye lens 23 are located inside the mounting bracket, and the mounting bracket 21 mainly bears the impact.
[0044] like Figure 1 and Figure 2 As shown, in a specific embodiment of the nickel-saving stainless steel air defense door provided in this utility model, a buffer sleeve 13 is also included. The buffer sleeve 13 is arranged around the receiving cavity and connected to the door body 10.
