DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-5 As shown, an anti-deformation and earthquake-resistant civil defense door provided by an embodiment of the utility model includes a wall body 1, a door frame 2 is fixed inside the wall body 1, a door body 3 is hinged on one side outer wall of the door frame 2, a hand wheel 10 is provided on one side outer wall of the door body 3, a shock absorbing mechanism 11 is provided on one side outer wall of the door body 3, the shock absorbing mechanism 11 includes a cylinder body 12 fixed to the door body 3, an extrusion column 13 is movably inserted inside the cylinder body 12, a retaining ring 14 is integrally formed on the outer wall of one end of the extrusion column 13, the retaining ring 14 is located inside the cylinder body 12, a spring 16 is provided inside the cylinder body 12, a filling nozzle 21 is integrally formed on the top outer wall of the cylinder body 12, and a filter assembly 20 is threadedly connected to the inside of the filling nozzle 21.

[0024] Specifically, in this embodiment, it includes a wall 1, a door frame 2 is fixed inside the wall 1, and a door body 3 is hinged on an outer wall of one side of the door frame 2. After the civil air defense door in the prior art is closed, the door will be embedded in the inner part of the door frame. When the civil air defense door causes the door frame to deform due to an earthquake, the door will be stuck inside the door frame, thereby causing the civil air defense door to be unable to open normally. The door body 3 in the present utility model is located on the side of the door frame 2 to prevent the door body 3 from being stuck due to the deformation of the door frame 2, and the door hinges connected between the door frame 2 and the door body 3 are preferably three, and there are two door hinges in the upper part and one door hinge in the lower part, which can effectively prevent the door hinges from being deformed due to long-term load-bearing. A hand wheel 10 is provided on the outer wall of one side of the door body 3. The hand wheel 10 is a rotating mechanism for locking the door body in the prior art. A shock absorbing mechanism 11 is provided on the outer wall of one side of the door body 3. The number of the shock absorbing mechanisms 11 is limited to two, and they are fixed on the door body 3 in an upper and lower distribution manner. On the outer wall of the open side, the shock absorbing mechanism 11 includes a cylinder body 12 fixed to the door body 3, and an extrusion column 13 is movably inserted inside the cylinder body 12. A retaining ring 14 is integrally formed on the outer wall of one end of the extrusion column 13. The retaining ring 14 prevents the extrusion column 13 from separating from the cylinder body 12. The retaining ring 14 is located inside the cylinder body 12. A spring 16 is arranged inside the cylinder body 12. When the extrusion column 13 compresses the spring 16, the spring 16 can play a shock absorbing role. A filling nozzle 21 is integrally formed on the top outer wall of the cylinder body 12. An appropriate amount of lubricating oil can be added to the inside of the cylinder body 12 through the filling nozzle 21 for lubrication of the extrusion column 13 during movement. The inside of the filling nozzle 21 is threadedly connected with a filter assembly 20. At the same time, the filling nozzle 21 plays a ventilating role, so that the air pressure inside and outside the cylinder body 12 can be balanced to prevent the air inside the cylinder body 12 from hindering the movement of the extrusion column 13. The filter assembly 20 can filter dust in the air.

[0025] The utility model provides an anti-deformation and earthquake-resistant civil air defense door, which has a cylinder body 12, a spring 16 and an extrusion column 13. After the door body 3 is opened, the spring 16 inside the cylinder body 12 is squeezed by the extrusion column 13, so that the spring 16 can buffer the door body 3, preventing the door body 3 and the wall 1 from vibrating violently due to collision, and also preventing the hand wheel 10 and the wall 1 from being deformed and damaged due to collision, thereby extending the service life of the civil air defense door.

[0026] In another embodiment provided by the present utility model, Figure 2 and Figure 5As shown, a guide post 15 is fixed to the inner wall of one side of the cylinder body 12, a guide hole 17 is opened inside the extrusion post 13, and the guide post 15 is movably inserted inside the guide hole 17. By using the guide post 15 to be movably inserted inside the guide hole 17, the extrusion post 13 is more stable when moving; the spring 16 is sleeved on the outside of the guide post 15, and the spring 16 is sleeved on the outside of the guide post 15 so that the spring 16 can be stably compressed, and the extrusion post 13 is opened inside the air vent 23 connected to the guide hole 17, and the air vent 23 allows the guide hole 17 to be opened. The interior of the hole 17 is connected to the interior of the cylinder body to prevent the air inside the guide hole 17 from hindering the movement of the extrusion column 13. A sealing groove 18 is opened on the outer wall of the retaining ring 14, and a sealing ring 19 is arranged inside the sealing groove 18. The sealing ring 19 is used to prevent the lubricating oil inside the cylinder body 12 from flowing out; a rubber pad 22 is fixed to the outer wall of one side of the wall 1, and the rubber pad 22 is adapted to the shock absorbing mechanism 11. After the door body 3 is opened, the extrusion column 13 of the shock absorbing mechanism 11 can contact the rubber pad 22, so that the surface of the wall 1 will not be damaged by the extrusion column 13.

[0027] In another embodiment provided by the present utility model, Figure 3 and Figure 4 As shown, the door body 3 includes a side panel 1 4 and a side panel 2 5, and a support layer 6 is arranged between the side panel 1 4 and the side panel 2 5; the support layer 6 includes evenly distributed transverse ribs 7 and longitudinal ribs 8, and the transverse ribs 7 and the longitudinal ribs 8 are filled with rock wool blocks 9. By arranging the rock wool blocks 9 between the side panels 1 4 and the side panels 2 5, the self-weight of the door body 3 is reduced, and the door hinges can be effectively prevented from being deformed due to long-term load. At the same time, the criss-crossed transverse ribs 7 and longitudinal ribs 8 can support the side panels 1 4 and the side panels 2 5, so that the door body 3 can maintain a higher strength, and the rock wool blocks 9 can achieve a better thermal insulation effect of the door body 3.

[0028] Working principle: When in use, the filter assembly 20 is threadedly separated from the filling nozzle 21, a small amount of lubricating oil is added to the inside of the cylinder body 12 through the filling nozzle 21, and then the filter assembly 20 is threadedly connected to the filling nozzle 21; when the door body 3 is opened, the extrusion column 13 of the shock absorbing mechanism 11 is in contact with and squeezed with the rubber pad 22, and the extrusion column 13 compresses the spring 16 after being subjected to force, so that the door body 3 will not collide with the wall 1 and vibrate, and the hand wheel 10 will not collide with the wall 1; at the same time, the lubricating oil inside the cylinder body 12 is squeezed and contacts with the guide column 15, so that the guide column 15 is smoother when it is movably plugged into the inside of the guide hole 17.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
