Technical Field

[0001] This application relates to the technical field of air defense doors, and in particular to an air defense door based on motor opening and closing. Background Technology

[0002] Civil defense doors, also known as air defense doors, are special doors used to ensure the safety of personnel and the protection of materials during wartime or emergency situations. These doors are usually installed in underground air-raid shelters, basements, or specialized civil defense projects, and have characteristics such as fire resistance, explosion resistance, and gas resistance.

[0003] Regarding the aforementioned technologies, the inventors discovered that existing air defense doors are relatively large and heavy, making them difficult to open and close, which is not conducive to easy use. Utility Model Content

[0004] To facilitate easy opening and closing, this application provides a civil defense door based on motor-driven opening and closing.

[0005] This application provides a technical solution for a motor-operated air-raid shelter door, which employs the following method:

[0006] A type of air-raid shelter door based on motor-operated opening and closing includes a door frame and a sealing door. The door frame includes an outer frame and an inner frame. The inner frame is installed on the inner side of the outer frame and is integrally formed with the outer frame. An equipment box is fixedly installed on the lower end face of the outer frame. A positioning door shaft for installing the sealing door is provided in the equipment box. The positioning door shaft is rotatably connected to the equipment box. An electric opening and closing assembly for driving the positioning door shaft to rotate is installed in the equipment box. An extension shell is also installed on the outer side of the equipment box. The extension shell is fixedly connected to the equipment box, and a manual operating component for driving the positioning door shaft to rotate is installed in the extension shell.

[0007] By adopting the above technical solution, and designing the door frame as a structure with an outer frame and an inner frame that fit together, the door can be installed and sealed using the outer frame for ease of use. Once the outer frame is embedded and fixed to the wall, it ensures stable rotation and adjustment of the door. Furthermore, by fixing an equipment box to the lower end of the outer frame, and using the equipment box to install the positioning door hinge, the lower end of the positioning door hinge is installed in the equipment box, and the upper end can pass through the equipment box and connect with the door frame. This facilitates the direct fitting and fixing of the door onto the positioning door hinge during installation. In actual use, the positioning door hinge can be rotated to... This system allows for flexible rotation and adjustment of the sealing door, enabling stable opening and closing. An electrically operated opening and closing assembly is installed in the equipment housing to drive the positioning door shaft, allowing for automatic opening and closing of the sealing door. An extension shell is fixedly installed on the outer side of the equipment housing to facilitate the installation of manual operating components. These components are stably mounted below the door frame, with one end of the operating head extending outwards for manual operation of the sealing door.

[0008] Optionally, one side of the outer frame is provided with several stabilizing bearings for the positioning door shaft to pass through, and the stabilizing bearings are fixedly connected to the outer frame.

[0009] By adopting the above technical solution and setting several stabilizing bearings on one side of the outer frame, it is ensured that the positioning door hinge can pass through stably during use. This not only increases the strength of the positioning door hinge but also facilitates the stability of the door installation, making it more convenient to open and close the door.

[0010] Optionally, the door sealing includes a main door panel and an inner shell that cooperates with the inner frame. The inner shell is installed on the inner side of the main door panel and is fixedly connected to the main door panel.

[0011] By adopting the above technical solution, the sealing door is designed with a structure in which the main door panel and the inner shell cooperate. This ensures that the main door panel can be used as the main structure for closing the air-raid shelter passage when in use. By installing the inner shell structure on the inner side of the main door panel, the main door panel can be better locked after it is closed on the door frame, and the locking rod can be easily engaged with the inner shell.

[0012] Optionally, a plurality of connecting brackets are installed on the outer side of the main door panel. The connecting brackets are evenly arranged from top to bottom and are fixedly connected to the main door panel.

[0013] By adopting the above technical solution, by installing a connecting bend frame on the outer side of the main door panel, the main door panel can be stably installed on the positioning door hinge through the connecting bend frame, and the connecting bend frame and the positioning door hinge are fixed together to ensure that the main door panel can be driven to rotate through the positioning door hinge during use.

[0014] Optionally, the connecting bend includes an outer rod and a connecting inner plate. The outer rod is fixedly installed on the outer side of the main door panel, and the connecting inner plate is integrally formed on the outer end of the outer rod and sleeved and fixed on the positioning door hinge.

[0015] By adopting the above technical solution, the connecting bend frame is designed with an outer rod and a connecting inner plate that cooperate to ensure that it can be fixedly installed on the main door panel during use. In this way, the main door panel can be driven to flip by multiple sets of outer rods. Furthermore, by setting the connecting inner plate on the outer rod, it can be fitted and fixed on the positioning door hinge during installation. This allows the connecting bend frame to be flipped by the positioning door hinge during use.

[0016] Optionally, the equipment box includes a main shell and a cover. The cover is fastened to the front end of the main shell and is fixedly connected to the main shell. A stabilizing block is also fixedly installed on the inner side of the main shell.

[0017] By adopting the above technical solution, the equipment box is designed with a main shell and a cover that fit together. When in use, the electric start-stop component and the positioning door hinge can be installed through the main shell. This ensures that the electric start-stop component can drive the positioning door hinge to rotate and adjust during use. At the same time, by fixing a stabilizing block on the inner side of the main shell, the stability of the electric start-stop component during rotation can be increased after it is installed in the main shell. The cover is used to seal the main shell.

[0018] Optionally, the electric start / stop assembly includes a drive motor and an electric start shaft. The drive motor is fixedly installed in the main housing, and the electric start shaft is rotatably installed on the stabilizing block. The lower end of the electric start shaft is connected to the output end of the drive motor, and the electric start shaft is connected to the positioning door shaft through a first belt.

[0019] By adopting the above technical solution, the electric start-stop assembly is designed as a structure in which a drive motor and an electric start shaft cooperate. When in use, the drive motor can drive the electric start shaft to rotate. The electric start shaft is connected to the positioning door shaft through the first belt, and thus the electric start shaft can drive the positioning door shaft to rotate synchronously. Both the electric start shaft and the positioning door shaft are fitted with corresponding pulleys to facilitate better connection through the first belt.

[0020] Optionally, the manual operating component includes a drive short shaft, an operating long shaft, and a turntable. The drive short shaft and the operating long shaft are both rotatably mounted in the extension housing and are connected by a second belt. A small gear is fixedly mounted on the drive short shaft, and a large gear that meshes with the small gear is fixedly mounted on the positioning door shaft. The turntable is fixedly mounted on the head of the operating long shaft.

[0021] By adopting the above technical solution, the manual operating component is designed with a drive short shaft, an operating long shaft, and a turntable. In convenient operation, the drive short shaft uses a small gear and a large gear for transmission. A second belt connects the drive short shaft and the operating long shaft, ensuring that the operator only needs to rotate the turntable to rotate the operating long shaft, which in turn drives the drive short shaft to rotate synchronously. The drive short shaft then drives the positioning door shaft to rotate, allowing the door to open and close. During operation, the small gear on the drive short shaft drives the large gear on the positioning door shaft for effortless rotation. Furthermore, the small pulley on the operating long shaft and the corresponding large pulley on the drive short shaft, connected to the two ends of the second belt respectively, further reduce effort during operation. This two-stage effort-saving approach ensures more effortless operation during opening and closing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By fixing the equipment box to the lower end face of the door frame, this application ensures that the electric opening and closing component and the positioning door hinge can be installed through the equipment box during use. When in use, the positioning door hinge passes through the stabilizing bearing seat, which facilitates the sealing of the door. It can be stably installed through the connecting bending frame, ensuring that when the door needs to be opened or closed, it can be opened or closed simply by rotating the positioning door hinge. In this way, it can be used to achieve automatic flipping through the electric opening and closing component, or it can be manually flipped and opened / closed through the manual operating component. It is very convenient to use. Furthermore, the manual operating component adopts a two-stage force-saving structure, ensuring that the operation is very easy when manually opening and closing.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a civil defense door based on motor-driven opening and closing. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, a type of air-raid shelter door based on motor opening and closing includes a door frame 1 and a sealing door 2. The door frame 1 includes an outer frame 11 and an inner frame 12. The inner frame 12 is installed on the inner side of the outer frame 11 and is integrally formed with the outer frame 11. An equipment box 3 is fixedly installed on the lower end face of the outer frame 11. A positioning door shaft 4 for installing the sealing door 2 is provided in the equipment box 3. The positioning door shaft 4 is rotatably connected to the equipment box 3. An electric opening and closing assembly 5 for driving the positioning door shaft 4 to rotate is installed in the equipment box 3. An extension shell 6 is also installed on the outer side of the equipment box 3. The extension shell 6 is fixedly connected to the equipment box 3, and a manual operating component 7 for driving the positioning door shaft 4 to rotate is installed in the extension shell 6. By designing the door frame 1 as a structure where the outer frame 11 and the inner frame 12 cooperate, the sealing door 2 can be installed through the outer frame 11 for easy use. Once the outer frame 11 is embedded and fixed to the wall, the sealing door 2 can be stably rotated and adjusted. Furthermore, by fixing the equipment box 3 to the lower end of the outer frame 11, the positioning door hinge 4 is installed through the equipment box 3. After the lower end of the positioning door hinge 4 is installed in the equipment box 3, the upper end can pass through the equipment box 3 and connect with the door frame 1. This allows the sealing door 2 to be directly fitted and fixed onto the positioning door hinge 4 during installation. In actual use, the sealing door 2 can be rotated to adjust its position. The flexible tilting adjustment of the sealing door 2 enables stable opening and closing. An electric opening and closing assembly 5, which drives the positioning door shaft 4, is installed in the equipment box 3. This allows the positioning door shaft 4 to rotate automatically, thus achieving automatic opening and closing of the sealing door 2. An extension shell 6 is fixedly installed on the outer surface of the equipment box 3 to facilitate the installation of a manual operating component 7. This ensures the manual operating component 7 can be stably installed below the door frame 1, with one end of the operating head extending outwards for easy operation by the operator to rotate and open / close the sealing door 2. Several stabilizing bearings 111 are provided on one side of the outer frame 11 for the positioning door shaft 4 to pass through, and the stabilizing bearings 111 are fixedly connected to the outer frame 11. By setting several stabilizing bearings 111 on one side of the outer frame 11, it is ensured that the positioning door shaft 4 can pass through stably during use. This not only increases the strength of the positioning door shaft 4, but also facilitates the stability of the sealing door 2 installation, making it more convenient to open and close the sealing door 2.

[0031] Reference Figure 2 and Figure 5As shown, the sealing door 2 includes a main door panel 21 and an inner shell 22 that cooperates with the inner frame 12. The inner shell 22 is installed on the inner side of the main door panel 21 and is fixedly connected to the main door panel 21. By designing the sealing door 2 with a structure in which the main door panel 21 and the inner shell 22 cooperate, it is ensured that the main door panel 21 can be used as the main structure for closing the air-raid shelter passage during use. By installing the inner shell 22 on the inner side of the main door panel 21, it is easier for the main door panel 21 to be locked after it is closed on the door frame 1, and it is easier for the locking rod to be engaged with the inner shell 22. Several connecting bends 23 are installed on the outer side of the main door panel 21. The connecting bends 23 are evenly arranged from top to bottom and are fixedly connected to the main door panel 21. By installing a connecting bend bracket on the outer side of the main door panel 21, the main door panel 21 can be stably mounted on the positioning door hinge 4 via the connecting bend bracket 23, and the connecting bend bracket 23 and the positioning door hinge 4 are fixed together to ensure that the main door panel 21 can be rotated by the positioning door hinge 4 during use. The connecting bend bracket 23 includes an outer rod 231 and a connecting inner plate 232. The outer rod 231 is fixedly installed on the outer side of the main door panel 21, and the connecting inner plate 232 is integrally formed on the outer end of the outer rod 231 and is sleeved and fixed on the positioning door hinge 4. By designing the connecting bend frame 23 into a structure in which the outer rod 231 and the connecting inner plate 232 cooperate, it is ensured that the outer rod 231 can be fixedly installed on the main door panel 21 during use. In this way, the main door panel 21 can be driven to flip by multiple sets of outer rods 231. Furthermore, by setting the connecting inner plate 232 on the outer rod 231, it is ensured that the connecting inner plate 232 can be sleeved and fixed on the positioning door hinge 4 during installation. This allows the connecting bend frame 23 to be driven to flip by the positioning door hinge 4 during use.

[0032] Reference Figure 3 and Figure 4 As shown, the equipment box 3 includes a main shell 31 and a cover 32. The cover 32 is fastened to the front end of the main shell 31 and is fixedly connected to the main shell 31. A stabilizing block 33 is also fixedly installed on the inner side of the main shell 31. By designing the equipment box 3 into a structure in which the main shell 31 and the cover 32 cooperate, the electric start-stop assembly 5 and the positioning door shaft 4 can be installed through the main shell 31 for easy use. This ensures that the electric start-stop assembly 5 can drive the positioning door shaft 4 to rotate and adjust during use. At the same time, by fixing the stabilizing block 33 on the inner side of the main shell 31, the stability of the electric start-stop assembly 5 during rotation is increased after it is installed in the main shell 31. The cover 32 is used to seal the main shell 31.

[0033] Reference Figure 3As shown, the electrically operated opening and closing assembly 5 includes a drive motor 51 and an electrically operated shaft 52. The drive motor 51 is fixedly installed in the main housing 31, and the electrically operated shaft 52 is rotatably installed on the stabilizing block 33. The lower end of the electrically operated shaft 52 is connected to the output end of the drive motor 51, and the electrically operated shaft 52 is connected to the positioning door shaft 4 via a first belt 521. By designing the electrically operated opening and closing assembly 5 as a structure in which the drive motor 51 and the electrically operated shaft 52 cooperate, it is easy to use. The drive motor 51 can drive the electrically operated shaft 52 to rotate, and the electrically operated shaft 52 is connected to the positioning door shaft 4 via the first belt 521. Thus, the electrically operated shaft 52 can drive the positioning door shaft 4 to rotate synchronously. Both the electrically operated shaft 52 and the positioning door shaft 4 are fitted with corresponding pulleys for better connection via the first belt 521.

[0034] Reference Figure 3 and Figure 4 As shown, the manual operating component 7 includes a drive short shaft 71, an operating long shaft 72, and a turntable 73. Both the drive short shaft 71 and the operating long shaft 72 are rotatably mounted in the extension housing 6, and are connected by a second belt 721. A small gear 711 is sleeved and fixed on the drive short shaft 71, and a large gear 41 that meshes with the small gear 711 is sleeved and fixed on the positioning door shaft 4. The turntable 73 is fixedly mounted on the head of the operating long shaft 72. By designing the manual operating component 7 into a structure that combines a short drive shaft 71, a long operating shaft 72, and a turntable 73, the short drive shaft 71 can achieve transmission through the meshing of a small gear 711 and a large gear 41. Furthermore, the short drive shaft 71 and the long operating shaft 72 are connected by a second belt 721. This ensures that the operator only needs to rotate the turntable 73 to drive the long operating shaft 72, which in turn drives the short drive shaft 71 to rotate synchronously. The short drive shaft 71 then drives the positioning door shaft 4 to rotate, allowing the sealing door 2 to open. During operation, the small gear 711 on the short drive shaft 71 drives the large gear 41 on the positioning door shaft 4, achieving effortless rotation. The small pulley on the long operating shaft 72 and the corresponding large pulley on the short drive shaft 71, with the two ends of the second belt 721 connected to the small and large pulleys respectively, further reduce effort during operation. This two-stage effort-saving approach ensures more effortless operation during opening and closing.

[0035] The implementation principle of a motor-driven air-raid shelter door according to an embodiment of this application is as follows: In actual use, the operator can start the drive motor 51 to drive the positioning door shaft 4 to rotate and adjust, and then drive the sealing door 2 to perform flip-opening and closing operations through the positioning door shaft 4. When manual opening and closing is required, the operator can rotate the turntable 73 to rotate the operating long shaft 72, and drive the driving short shaft 71 to rotate synchronously through the operating long shaft 72, and drive the positioning door shaft 4 to rotate synchronously through the driving short shaft 71, and then drive the sealing door 2 to perform flip-opening and closing operations through the positioning door shaft 4.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
