At the same time, the setting of the observation component is conducive to the realization of the observation function. The setting of the threaded opening is conducive to the rotation of the threaded rod 11 through the thread line, which in turn is conducive to the control of the window 8 by the threaded rod 11 and the stability of the overall use.

[0037] It can also be understood that the threaded rod 11 is threadedly connected to the connecting block 9 and the connecting block 10 through a threaded through hole, and connecting plates 12 are fixed to the front of the door body 2 and the door frame 1, and a locking assembly 13 movably connected thereto is provided on the connecting plate 12, and a reinforcement assembly 14 movably connected to the door frame 1 is provided on the front of the door body 2, and a handle 15 is fixed to the front of the door body 2.

[0039] It should also be noted that the observation assembly includes a reinforcement ring 3, a sealing ring 4, two glass plates 5, a movable plate 6 and a traction block 7. The reinforcement ring 3 is fixed to the inner side of the door body 2. The reinforcement ring 3 is a shock-absorbing rubber. The shock-absorbing rubber is arranged to prevent the shock force received by the door body 2, which is beneficial to the stability of the observation assembly. The sealing ring 4 is fixed to the inner side of the reinforcement ring 3. The front side of the door body 2 is provided with an observation port that runs through to the back side thereof. The reinforcement ring 3 is fixed to the inner side of the observation port, and the front side of the door body 2 is provided with a sliding channel.

[0040] It is not difficult to understand that the setting of the sliding channel is conducive to the sliding of the movable plate 6, which is conducive to the stable use of the overall component. The sealing ring 4 is used to seal the component, and the material setting of the reinforcement ring 3 is used to facilitate the stable use of the overall observation component.

[0041] It is not difficult to see that the two glass plates 5 are fixed to the inner side of the reinforcement ring 3. The glass plates 5 are made of polycarbonate. The material setting is conducive to improving the firmness of the glass plates 5, and thus is conducive to the stability of the overall structure. The space between the front and rear glass plates 5 is filled with inert gas. The inert gas setting is conducive to improving the stability of the glass plates 5 and improving the overall safety performance. The right sides of the reinforcement ring 3 and the sealing ring 4 are both provided with movable openings.

[0042] The provision of the movable buckle facilitates the stable displacement of the movable plate 6, thereby facilitating the realization of the shielding function of the glass plate 5, thereby facilitating the improvement of the flexibility of the use of the observation component.

[0043] In simple terms, the movable opening is located between the front and rear glass plates 5, the movable plate 6 is slidably connected to the reinforcement ring 3 and the sealing ring 4 through the movable opening, the movable plate 6 is movably connected to the door body 2, the reinforcement ring 3 and the sealing ring 4, the right side of the movable plate 6 is fixed to the traction block 7, and the movable plate 6 and the traction block 7 are both slidably connected through a sliding channel.

[0044] This embodiment realizes observation of the outside of the civil air defense door through the setting of the observation component, and at the same time, the material setting of the door body 2 and the observation component is coordinated to improve the stability of the overall structure. The coordination of the threaded opening and the sliding channel further improves the stability of the overall structure. At the same time, the setting of the locking component 13 and the reinforcement component 14 is coordinated to improve the stability of the door frame 1 and the door body 2, thereby improving the safety performance of the overall structure.

[0045] See also Figure 5 In order to improve the overall stability, the locking assembly 13 in this embodiment includes a movable column 1301, a displacement column 1302, a connecting column 1303, a connecting column 1304, a top support block 1305, a supporting block 1306 and a limiting ball 1307. The setting of the top support block 1305 and the supporting block 1306 provides space for the movement of the limiting ball 1307, which is conducive to adjusting the limiting ball 1307, and further conducive to the realization of the locking function. The outer side of the movable column 1301 is movably connected to the connecting plate 12 The outer side of the displacement column 1302 is movably connected to the movable column 1301, the bottom of the displacement column 1302 is fixed to the connecting column 1303, and the bottom of the connecting column 1303 is fixed to the connecting column 1304. Through this arrangement, it is beneficial to leave space for the movement of the limiting ball 1307, and then it is beneficial to realize the adjustment function of the limiting ball 1307. The outer side of the connecting column 1304 is fixed to the top support block 1305 and the supporting block 1306 from top to bottom, and the inner side of the movable column 1301 is movably connected to the limiting ball 1307.

[0046] It should be explained that, through the movement of the limiting ball 1307, the movable column 1301 is limited, thereby achieving the locking of the door body 2 and the door frame 1, and further improving the stability of use.

[0047] It also needs to be explained that the displacement column 1302 extends to the inner cavity of the movable column 1301, and a spring is fixed on the outside of the displacement column 1302 located in the inner cavity of the movable column 1301. The spring setting is beneficial to provide support force for the displacement column 1302, which is beneficial to the stability of the overall assembly. The bottom of the spring is fixed to the inner cavity wall of the movable column 1301, and the inner side of the movable column 1301 is provided with a limit opening that extends through to the outside thereof, and the limit ball 1307 is fitted with the limit opening and the top support block 1305.

[0048] In this embodiment, the top support block 1305 and the supporting block 1306 are adjusted by the movement of the displacement column 1302, so that the limiting ball 1307 moves in the movable column 1301, thereby limiting the movable column 1301 through the limiting opening, which is conducive to achieving a stable effect on the door frame 1 and the door body 2.

[0049] See also Figure 6 In order to improve the safety performance of the overall structure, the reinforcement component 14 in this embodiment includes a handle 1401, a locking block 1402, a plug-in column 1403 and a plug-in block 1404. The handle 1401 is movably connected to the door frame 1, the locking block 1402 is fixed to the front of the door body 2, the top of the plug-in column 1403 is fixed to the handle 1401, the inner side of the plug-in block 1404 is fixed to the plug-in column 1403, and the outer side of the plug-in block 1404 is movably connected to the locking block 1402.

[0050] In addition, by sliding the handle 1401 , the plug-in column 1403 drives the plug-in block 1404 to be inserted into the locking block 1402 , thereby achieving the locking of the handle 1401 and the locking block 1402 .

[0051] Moreover, a displacement channel is provided on the front of the door frame 1, and the handle 1401 is slidably connected to the door frame 1 through the displacement channel. The setting of the displacement channel is beneficial to the stability of the sliding of the handle 1401, and thus is beneficial to improving the use effect of the overall component. The bottom of the plug-in column 1403 is fitted with a support block fixed to the front of the door frame 1, and a movable opening is provided on the top of the locking block 1402. The setting of the movable opening is beneficial to the card connection between the locking block 1402 and the plug-in block 1404, and thus is beneficial to the stabilization effect of the locking block 1402 and the plug-in block 1404, thereby improving the stability of the overall structure. The plug-in block 1404 is slidably connected to the locking block 1402 through the movable opening.

[0052] In this embodiment, the plug-in block 1404 is adjusted by sliding the handle 1401, so that the plug-in block 1404 and the locking block 1402 are locked, thereby improving the stability between the door frame 1 and the door body 2, and further improving the safety performance of the overall structure.

[0053] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0054] The working principle of the above embodiment is:

[0055] Fix the door frame 1, close the door body 2 through the hinge action, slide the handle 1401 downward, insert the locking block 1402, and fit the plug-in block 1404 with the locking block 1402 to achieve the initial reinforcement of the door body 2 and the door frame 1, then press the displacement column 1302 to move the top support block 1305 downward, so that the limiting ball 1307 is located between the connecting column 1303 and the top support block 1305, so that the limiting ball 1307 is received inside the movable column 1301, and then the movable column 1301 is inserted into the connecting plate 12, so as to complete the secondary stabilization of the door frame 1 and the door body 2. When it is necessary to observe the outside of the civil air defense door, the traction block 7 can be held and slid to the right, so that the movable plate 6 is pulled out from between the two glass plates 5, so as to observe the outside world through the glass plates 5. When more direct contact with the external environment is needed, such as delivering objects or simple communication, the threaded rod 11 can be rotated so that the threaded rod 11 is rotated out of the connecting block 9, so that the window 8 is opened through the hinge action of the window 8 and the door body 2, and contact with the outside world is achieved. The overall use is convenient, and while being able to observe the outside world, the protection effect is good and the stability is high, thereby improving the safety performance.
