Description

Technical Field

[0001] The invention relates to the technical field of earthquake-resistant heat-insulating civil air defense doors, and in particular to an earthquake-resistant heat-insulating civil air defense door. Background Art

[0002] Civil air defense projects, also known as civil air defense fortifications, refer to underground protective buildings built separately to ensure the shelter of personnel and materials, civil air defense command, and medical rescue in wartime, as well as basements that can be used for air defense in wartime built in combination with ground buildings. Civil air defense projects are important facilities for preventing sudden enemy attacks, effectively sheltering personnel and materials, and preserving war potential. They are engineering guarantees for persisting in urban combat and supporting the anti-aggression war for a long time until victory.

[0003] According to announcement number CN112796633A, a civil air defense door is disclosed, comprising a door frame and a door leaf, the door leaf being hinged to the door frame, and a closed structure being arranged between the door frame and the door leaf; a groove for the door leaf is arranged around the door leaf, a receiving groove is arranged on the upper side of the door frame, a water absorption pad which is horizontally arranged and can be inserted into the groove on one side is slidably connected in the receiving groove, a water tank is fixedly arranged on the upper side of the door leaf, water pipes are vertically fixedly connected at both ends of the water tank corresponding to the water absorption pad, water outlet holes are arranged on one side of the water pipe close to the water absorption pad, a rotating shaft is rotatably arranged on the upper side of the water pipe corresponding to the water outlet hole, a valve plate is fixedly connected to the rotating shaft, slide grooves are horizontally arranged at both ends of the water absorption pad, and connecting rods slidably connected in the slide grooves are fixedly connected at the ends of each rotating shaft; a temperature-sensitive glass bulb is arranged in the door frame.

[0004] The above technical solution can effectively prevent the penetration of thick smoke. However, although the above technical solution can isolate the thick smoke, it does not have an earthquake-resistant function.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] See also Figure 1-9, an earthquake-resistant heat-insulating civil air defense door, comprising a wall 1, an insulation door 2 is arranged on the outer side of the wall 1, the bottom surface of the wall 1 is fixedly connected to the ground 3, the front side of the insulation door 2 is fixedly connected to a hanging mechanism 4, and the front side of the insulation door 2 is fixedly connected to a ground plug mechanism 5;

[0034] The hanging mechanism 4 includes a fixed block 401, and two first springs 402 are fixedly connected to the outer surface of the fixed block 401. Four limit blocks 405 are fixedly connected to the front of the heat insulation door 2. The inner wall of each group of limit blocks 405 is slidably connected to a push rod 404, and the end of the push rod 404 close to the first spring 402 is fixedly connected to the outer surface of the first spring 402. An electric induction valve 403 is fixedly connected to the front of the heat insulation door 2, and the inner wall of one of the push rods 404 is rotatably connected to a hook 408, and the outer surface of the hook 408 is rotatably connected to the inner wall of the heat insulation door 2. A mounting seat 406 is fixedly connected to the front of the wall 1, and a hook rod 407 is fixedly connected to the bottom surface of the mounting seat 406, and the outer surface of the hook 408 contacts the outer surface of the hook rod 407.

[0035] An L-shaped seat 6 is fixedly connected to the back of the heat-insulating door 2, and a worm 7 is rotatably connected to the inner wall of the L-shaped seat 6. The L-shaped seat 6 is an L-shaped supporting iron plate, which plays the role of supporting the worm 7. The worm 7 refers to a gear having one or more helical teeth and meshing with the worm wheel to form a staggered axis gear pair, and its dividing surface can be a cylindrical surface.

[0036] Three limit frames 8 are fixedly connected to the back side of the heat-insulating door 2, and the inner walls of two of the limit frames 8 are rotatably connected with worm wheels 9. The limit frames 8 are used to limit and fix the worm wheels 9, and play a role in stabilizing the worm wheels 9. The worm wheels 9 and worm 7 are often used to transmit motion and power between two staggered axes. The worm wheels 9 and worm 7 are equivalent to gears and racks in their middle planes, and the worm 7 is similar in shape to a screw.

[0037] The inner wall of the worm wheel 9 is threadedly connected with a threaded rod 10, and the outer surface of the threaded rod 10 is slidably connected to the inner wall of another limiting frame 8. When the threaded rod 10 rotates, it plays a role of lateral translation.

[0038] The front and back sides of the worm 7 are fixedly connected with manual wheels 11, one of which is located on the front side of the heat insulation door 2, and the other is located on the back side of the heat insulation door 2. Manual rotation of the manual wheels 11 by staff can drive the worm 7 to rotate, thereby providing a power source for locking the heat insulation door 2.

[0039] One end of the threaded rod 10 away from the limit frame 8 is rotatably connected to two driving rods 12, and one end of each driving rod 12 away from the threaded rod 10 is rotatably connected to a latch rod 13. The up and down swinging of the driving rod 12 can drive the latch rod 13 to be inserted into the wall 1 up and down, thereby locking the insulation door 2.

[0040] The specific implementation of this embodiment is as follows: a fixing block 401 is provided to fix the two first springs 402, and two push rods 404 are respectively engaged with the two directions of the electric sensing valve 403. The electric sensing valve 403 is an electric valve connected to an earthquake safety alarm. When the earthquake safety alarm sounds an alarm, the electric sensing valve 403 is triggered, and the elastic mechanism provided inside the electric sensing valve 403 is used to trigger it, and the blocks in the two directions can be recovered, thereby triggering the push rod 404 to move. The first spring 402 can be charged by engaging the push rod 404 with the electric sensing valve 403, and two limit blocks 405 are used to limit one push rod 404, respectively, to ensure that the push rod 404 will not deviate from the direction when moving. The mounting base 406 is used to fix the hook rod 407 to ensure the stability of the hook rod 407. If an aftershock occurs, the electric induction valve 403 is triggered to retract the block, thereby releasing the push rod 404. The restoring force of the first spring 402 can be used to push the push rod 404 to move. At this time, the push rod 404 is pushed and translated by the first spring 402. At this time, the push rod 404 drives the bottom end of the hook 408 to move. The rotational connection between the hook 408 and the heat insulation door 2 is utilized to allow the hook 408 to rotate as a whole at the center position. At this time, it can just cooperate with the hook rod 407 to form a hook-and-loop relationship, so that the heat insulation door 2 is lifted up as a whole, which plays a role in auxiliary stability, thereby alleviating the damage caused by aftershocks to the heat insulation door 2.

[0041] Embodiment 2

[0042] See also Figure 1-9 The ground insertion mechanism 5 includes a clamping seat 501, the inner wall of the clamping seat 501 is slidably connected with a clamping column 502, the bottom surface of the clamping column 502 is fixedly connected with a buffer 503, the outer surface of the buffer 503 contacts the inner wall of the ground 3, and the bottom surface of another push rod 404 contacts the upper surface of the clamping column 502, the inner wall of the clamping seat 501 is fixedly connected with four second springs 504, and one end of each group of second springs 504 close to each other is fixedly connected with a resistance block 505, and the upper surface of each resistance block 505 is fixedly connected with a toggle rod 506, and a cover plate 507 is arranged above the clamping seat 501, and the bottom surface of the cover plate 507 contacts the upper surface of the clamping seat 501, and four bolts 508 are arranged above the cover plate 507, and the bottom end of each bolt 508 passes through the cover plate 507 and is connected to the internal thread of the clamping seat 501.

[0043] The outer surface of each latch rod 13 is slidably connected to two limit seats 14, and the front side of each limit seat 14 is fixedly connected to the back side of the heat insulation door 2. The limit seats 14 play a role in restraining the latch rod 13, further ensuring the stability of the latch rod 13.

[0044] A positioning block 15 is provided on the outer side of the heat insulation door 2. The front side of the positioning block 15 is fixedly connected to the back side of the heat insulation door 2. The positioning block 15 prevents the threaded rod 10 from going out of the safety range and plays a role of limiting and standardizing.

[0045] A sealing strip 16 is fixedly connected to the back of the thermal insulation door 2, and a sealing groove 17 is fixedly connected to the front of the wall 1. The outer surface of the sealing strip 16 is in contact with the inner wall of the sealing groove 17. The cooperation between the sealing strip 16 and the sealing groove 17 can effectively prevent thick smoke from entering the interior of the civil air defense door, and has a good sealing effect.

[0046] Two rotating seats 18 are fixedly connected to the front side of the wall 1, and the outer surface of each rotating seat 18 is rotatably connected to a rotating frame 19. The right sides of the two rotating frames 19 are fixedly connected to the left sides of the thermal insulation door 2. The cooperation between the rotating seat 18 and the rotating frame 19 serves as the main support point of the thermal insulation door 2, so that the thermal insulation door 2 can be rotated to open and close.

[0047] The specific implementation of this embodiment is as follows: the overall stability of the heat insulation door 2 can be enhanced by providing a ground insertion mechanism 5, four second springs 504 can be fixed by using the clamping seat 501, and the resistance block 505 can be limited and moved by using the second spring 504. When not working, the clamping column 502 is located inside the clamping seat 501, and the four resistance blocks 505 are supported. At this time, the four second springs 504 are all squeezed by the stored force. If the electric induction valve 403 triggers the release of the push rod 404 at this time, the restoring force of the first spring 402 can be used to push the push rod 404 to move. At this time, the push rod 404 is pushed downward by the first spring 402, and the push rod 404 pushes the clamping column 5 02 moves downward until the clamping column 502 passes through the four resistance blocks 505, and the four second springs 504 instantly release the pressure to push out the resistance blocks 505, and the four resistance blocks 505 can be used to firmly clamp the clamping column 502. At this time, the clamping column 502 moves downward with the buffer 503, and the buffer 503 is clamped with the inner wall of the ground 3, so that the ground plug mechanism 5 can be combined with the ground 3, which can enhance the stability of the heat insulation door 2. If an aftershock occurs at this time, the buffer 503 itself is located inside the ground 3, so that the buffer 503 itself will not shake, and the buffer 503 itself has a buffering effect, which reduces the harm of aftershocks to the heat insulation door 2.

[0048] The working principle of the present invention is as follows: when in use, a professional first rotates the manual wheel 11, and then drives the worm 7 to rotate. By utilizing the meshing connection between the worm 7 and the worm wheel 9, when the worm 7 rotates, the worm wheel 9 can be driven to rotate. At this time, the worm wheel is limited and fixed by the limiting frame 8. By utilizing the threaded connection between the worm wheel 9 and the threaded rod 10, when the worm wheel 9 rotates, the threaded rod 10 can be driven to rotate. At this time, the translation of the threaded rod 10 can drive the driving rod 12 to move. By utilizing the rotational connection between the driving rod 12 and the latch rod 13, the driving rod 12 can be inserted into the wall 1 up and down against the latch rod 13, thereby achieving the effect of locking the heat insulation door 2. Then, the two first springs 402 can be fixed by providing a fixing block 401, and the two push rods 404 are respectively engaged with the two directions of the electric sensing valve 403. The electric sensing valve 403 is an electric valve connected to an earthquake safety alarm. When the earthquake safety alarm sounds an alarm, the electric sensing valve 403 is triggered. The elastic mechanism provided inside the electric sensing valve 403 is used to trigger the electric sensing valve 403, which can be recovered. The blocks in two directions can trigger the push rod 404 to move. The push rod 404 and the electric induction valve 403 can be connected to store the first spring 402. Two limit blocks 405 are used to limit one push rod 404 to ensure that the push rod 404 will not deviate from the direction when moving. The mounting seat 406 is used to fix the hook rod 407 to ensure the stability of the hook rod 407. If aftershock occurs, the electric induction valve 403 is triggered to retract the block, thereby releasing the push rod 404. The restoring force of the first spring 402 can be used to push the push rod 404 to move. At this time, the push rod 404 is pushed by the first spring 402 to move horizontally. At this time, the push rod 404 drives the bottom end of the hook 408 to move. By utilizing the rotational connection between the hook 408 and the heat insulation door 2, the hook 408 is rotated at the center position as a whole. At this time, it can just cooperate with the hook rod 407 to form a hook-and-loop relationship, so that the heat insulation door 2 is lifted up as a whole, which plays a role in auxiliary stability, and can further alleviate the damage caused by aftershocks to the heat insulation door 2;

[0049] The overall stability of the heat insulation door 2 can be enhanced by providing a ground plug mechanism 5, and the four second springs 504 can be fixed by the clamping seat 501, and the resistance block 505 can be limited and moved by the second spring 504. When not working, the clamping column 502 is located inside the clamping seat 501, and the four resistance blocks 505 are supported. At this time, the four second springs 504 are squeezed by the accumulated force. If the electric induction valve 403 triggers the release of the push rod 404, the restoring force of the first spring 402 can be used to push the push rod 404 to move. At this time, the push rod 404 is pushed downward by the first spring 402, and the push rod 404 moves downward against the clamping column 502. , until the clamping column 502 passes through the four resistance blocks 505, the four second springs 504 instantly release the pressure to push out the resistance blocks 505, and the four resistance blocks 505 can be used to firmly clamp the clamping column 502. At this time, the clamping column 502 moves downward with the buffer 503, and the buffer 503 is clamped with the inner wall of the ground 3, so that the ground plug mechanism 5 can be combined with the ground 3, which can enhance the stability of the insulation door 2. If an aftershock occurs at this time, the buffer 503 itself is located inside the ground 3, so that the buffer 503 itself will not shake, and the buffer 503 itself has a buffering effect, which reduces the harm of aftershocks to the insulation door 2.
