Description

Technical Field

[0001] This application relates to the technical field of civil air defense doors, and particularly to a ventilation civil air defense door. Background Art

[0002] A civil air defense door refers to a type of door used to prevent, restrict, and block the entry and exit of personnel. It is usually used in the safety protection system of buildings to ensure the safety inside the building and protect important areas from unauthorized personnel entering.

[0003] In the patent document with the publication number CN218150586U that has been announced, a ventilation civil air defense door is provided, which relates to the field of civil air defense doors. It includes a door body, a ventilation window is penetrated through the door body, and a hanging plate for closing the ventilation window is rotatably arranged on the door body; an installation seat is arranged on the door body near the ventilation window, and a plurality of limiting strips arranged in sequence along the thickness direction of the door body are arranged on the installation seat. The limiting strips are slidably arranged on the installation seat, and the sliding path of the limiting strips is located on the rotation path of the hanging plate; a fastening member for locking the limiting strips on the installation seat is arranged on the installation seat. This application has the effect of being able to adjust the opening angle of the hanging plate. When the hanging plate closes the ventilation window, the hanging plate will fit with the sealing ring, and at this time, the sealing performance at the connection between the hanging plate and the ventilation window can be further enhanced under the action of the sealing ring.

[0004] The above device realizes a certain range of limitation on the opening angle of the hanging plate through the installation seat. First, due to the size limitation of the installation seat itself, the limitation of the installation seat on the opening angle of the hanging plate also has certain limitations. For example, it is difficult for the installation seat to limit the maximum opening angle to reach 45º, 60º, 65º. Secondly, the civil air defense door has the function of blocking unauthorized personnel from entering. The hanging plate can be pushed open from outside the door, and the opening angle can also be adjusted or even disassembled from the outside, so as to directly enter the room through the ventilation window, making the civil air defense door lose its function of prohibiting entry.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0027] Refer to Figure 1, A ventilated air defense door, comprising a door panel mechanism 1, on the back of the door panel mechanism 1, a plurality of window panel mechanisms 4 arranged longitudinally side by side are installed. Below each window panel mechanism 4 on the back of the door panel mechanism 1, a positioning knob 5 is rotatably connected. On both sides of the window panel mechanism 4, a slide rail mechanism 2 is installed. Inside the slide rail mechanism 2, a fixing mechanism 3 is slidably connected. On the side of the fixing mechanism 3, a distance determining mechanism 6 is installed.

[0028] Referring to Figure 1 , 4 , the door panel mechanism 1 includes a door body 101. On the back of the door body 101, a ventilation window 102 penetrating the door body 101 is opened. On one side of the ventilation window 102 close to the back of the door body 101, a rubber pad 103 is fixedly connected. The window panel mechanism 4 includes a baffle 401. The baffle 401 is hinged to the upper end of the ventilation window 102. In front of the lower end of the baffle 401, a handle 402 is fixedly connected. The ventilation window 102 can play a role in ventilation. When the baffle 401 completely covers the back of the ventilation window 102, the baffle 401 will squeeze the rubber pad 103, thereby improving the airtight effect. The opening angle of the baffle 401 can be flexibly adjusted through the handle 402, which is simple and convenient.

[0029] Referring to Figure 4 , the slide rail mechanism 2 includes a rail plate 201. The rail plate 201 is installed on both sides of the ventilation window 102 on the back of the door body 101. In the middle of the front of the rail plate 201, a chute 202 is opened. The chute 202 is wider inside and narrower outside. Inside the slide rail mechanism 2, a fixing mechanism 3 is slidably connected. The fixing mechanism 3 includes two sliders 301. The two sliders 301 are respectively installed inside the chutes 202 on both sides of the ventilation window 102. The cross-section of the part of the slider 301 located inside the chute 202 is the same as the cross-section of the chute 202. A fixing knob 302 is threadedly connected to the upper end of the slider 301. The fixing knob 302 penetrates the bottom of the slider 301 and contacts the bottom of the chute 202. When adjusting the maximum opening angle, the sliders 301 on both sides of the ventilation window 102 are adjusted along the chute 202 to a suitable position, and the fixing knob 302 is rotated. The fixing knob 302 penetrates the bottom of the slider 301 and then squeezes the bottom of the chute 202, so that the slider 301 is fixed under the action of the fixing knob 302.

[0030] Referring to Figure 4, a sleeve 303 is fixedly connected to the front of the slider 301. First positioning holes 304 are provided at corresponding positions on both sides of the sleeve 303. An inner tube 305 is slidably connected inside the sleeve 303. Second positioning holes 306 that are at the same horizontal height as the first positioning holes 304 and are arranged evenly are provided on both sides of the inner tube 305. A stop rod 307 is fixedly connected to the front end of the inner tube 305. A guide plate 308 is fixedly connected to one side of the sleeve 303 above the first positioning hole 304. A plug plate 309 is slidably connected to the middle of the guide plate 308. A plate body with a smaller size is arranged below the plug plate 309. After the position of the slider 301 is fixed, the inner tube 305 inside the sleeve 303 is extracted to extend the total length of the sleeve 303 and the inner tube 305, causing the stop rod 307 to move forward. When the baffle 401 is opened at a certain angle, the limiting operation will be completed under the action of the stop rod 307.

[0031] Refer to Figure 3 , 4 , the distance-determining mechanism 6 includes an insertion roller 601. The insertion roller 601 passes through the first positioning hole 304 and the second positioning hole 306. A jack 602 is provided at one end of the insertion roller 601. The size of the jack 602 is the same as the size of the plate body below the plug plate 309. After the relative positions of the sleeve 303 and the inner tube 305 are determined, the insertion roller 601 is passed through the first positioning hole 304 and the corresponding second positioning hole 306, and the plug plate 309 is pushed so that the plug plate 309 passes through the insertion roller 601, thereby fixing the relative positions of the insertion roller 601, the sleeve 303, and the inner tube 305.

[0032] Refer to Figure 3 , a pressure-receiving plate 403 is fixedly connected to the lower end of the baffle 401. A pressure-receiving hole 404 that penetrates up and down is provided on the pressure-receiving plate 403. The size of the pressure-receiving hole 404 is similar to the size of the positioning knob 5. After the baffle 401 blocks the ventilation window 102, the handle 402 is pressed so that the baffle 401 is completely fitted into the ventilation window 102. At this time, the pressure-receiving hole 404 sleeves the outer side of the positioning knob 5, and the positioning knob 5 is rotated so that the upper plate body of the positioning knob 5 presses against the plate bodies at the upper and lower positions of the pressure-receiving hole 404, thereby fixing the position of the baffle 401.

[0033] Working principle: The ventilation window 102 can play a role in ventilation. When the baffle 401 completely covers the back of the ventilation window 102, the baffle 401 will squeeze the rubber pad 103, thereby improving the airtight effect. The opening angle of the baffle 401 can be flexibly adjusted through the handle 402, which is simple and convenient. When adjusting the maximum opening angle, the sliders 301 on both sides of the ventilation window 102 are adjusted along the sliding grooves 202 to appropriate positions, and the fixing knob 302 is rotated. The fixing knob 302 penetrates the bottom of the slider 301 and squeezes the bottom of the sliding groove 202, so that the slider 301 is fixed under the action of the fixing knob 302. After the position of the slider 301 is fixed, the inner tube 305 inside the sleeve 303 is extracted to extend the total length of the sleeve 303 and the inner tube 305, causing the stop lever 307 to move forward. When the baffle 401 is opened at a certain angle, the limit operation will be completed under the action of the stop lever 307;

[0034] When the relative positions of the sleeve 303 and the inner tube 305 are determined, the insertion roller 601 is inserted through the first positioning hole 304 and the corresponding second positioning hole 306 at the corresponding position, and the insertion plate 309 is pushed so that the insertion plate 309 penetrates the insertion roller 601, thereby fixing the relative positions of the insertion roller 601, the sleeve 303, and the inner tube 305. After the baffle 401 blocks the ventilation window 102, the handle 402 is pressed so that the baffle 401 is completely fitted into the ventilation window 102. At this time, the pressing hole 404 sleeves the outer side of the positioning knob 5, and the positioning knob 5 is rotated so that the upper end plate body of the positioning knob 5 presses against the plate bodies at the upper and lower positions of the pressing hole 404, thereby fixing the position of the baffle 401.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and the inventive concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
