Technical Field
[0001] This utility model relates to the field of roller shutter door frame technology, specifically a novel door frame structure for a fast roller shutter door. Background Technology
[0002] A roller shutter door is a type of door made by connecting many strips of material side by side. These strips are linked together in a multi-jointed manner and rotate up and down within a fixed track, with the roller at the top of the door as the axis. When the door is opened, it rolls up like a bamboo curtain, hence the name.
[0003] While existing roller shutter door frames provide installation for the roller shutter, they fail to protect it, causing the roller shutter to collide with the ground during lowering and resulting in damage. Furthermore, traditional roller shutters are not efficient at opening and closing, leading to jamming and reduced equipment efficiency. Therefore, a new frame structure for high-speed roller shutters has been developed. Utility Model Content

[0006] As a preferred technical solution of this utility model: an infrared monitoring device 1, an infrared monitoring device 2 and a power device are fixedly installed on the outer wall of the door frame body, and the power output shaft of the power device is fixedly installed on the roller shutter door body.

[0008] As a preferred technical solution of this utility model: the placement block, spring three and limiting rod are all fixedly assembled with the inner wall of the placement groove, and the protective plate is slidably connected with the inner wall of the placement groove.
[0009] As a preferred technical solution of this utility model: the limiting plate and the connecting rod are both slidably connected to the inner wall of the placement shell, and the rotating block II is fixedly assembled to the outer wall of the rotating rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This novel frame structure for a high-speed rolling shutter door allows the door body to move. When the door body moves, it applies pressure to the rollers, causing the rollers to move the mounting shell along the inner wall of the placement slot. This pressure on the mounting shell then applies pressure to the connecting block, which in turn applies pressure to the second spring. The moving connecting block then rotates the first rotating block and the rotating column along the inner wall of the fixed block. The rotation of the first rotating block then rotates the extension rod and the placement shell, causing the placement shell to apply pressure to the first pair of springs and the limiting plate. The limiting plate, receiving pressure, moves along the inner wall of the placement shell. The elastic potential energy of the first and second springs is then released, causing them to drive the connecting block to apply pressure to the mounting shell. The mounting shell then drives the rollers to apply pressure to the outer wall of the rolling shutter door body. This design makes the rolling shutter door body more stable during operation, preventing jamming during movement.
[0013] 2. The new frame structure of this high-speed rolling shutter door, when the rolling shutter door body is falling, applies pressure to the protective plate through the rolling shutter door body. After being subjected to pressure, the protective plate will drive the rotating plate and the cylinder to rotate on the inner wall of the placement block. When the rotating plate rotates, it will apply pressure to the third spring, causing the third spring to expand and contract under pressure. The limiting rod will limit the rotating plate, so that after the rotating plate rotates to a certain position, it will limit the rolling shutter door body, thereby protecting the rolling shutter door body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 - Figure 6A novel door frame structure for a high-speed rolling shutter door includes a door frame body 1. The inner wall of the door frame body 1 has a placement groove 6, and the inner wall of the placement groove 6 is provided with a protective component 7. A fixing plate 23 is fixedly mounted on the inner wall of the placement groove 6. One end of a second spring 22 is fixedly mounted on the outer wall of the fixing plate 23. A connecting block 10 is fixedly mounted on the other end of the second spring 22. A fixing block 11 is fixedly mounted on the outer wall of the connecting block 10. A rotating column 12 is rotatably connected to the inner wall of the fixing block 11. A rotating block 13 is fixedly mounted on the outer wall of the rotating column 12. A fixing block 13 is fixedly mounted on the outer wall of the rotating block 13. One end of the extension rod 14 is fixedly fitted with a placement shell 15. One end of the spring 16 is fixedly fitted with the inner wall of the placement shell 15. The other end of the spring 16 is fixedly fitted with a limit plate 17. One end of the connecting rod 18 is fixedly fitted with the outer wall of the limit plate 17. The other end of the connecting rod 18 is fixedly fitted with a rotating block 19. The inner wall of the placement groove 6 is fixedly fitted with an installation block 20. The inner wall of the installation block 20 is rotatably connected to a rotating rod 21. The outer wall of the connecting block 10 is fixedly fitted with an installation shell 8. The inner wall of the installation shell 8 is rotatably connected to a roller 9.
[0024] In the above structure, when the roller shutter body 5 moves, pressure is applied to the roller 9, causing it to be pressured and push the mounting shell 8 to move along the inner wall of the placement groove 6. During the movement, the mounting shell 8 applies pressure to the connecting block 10, causing the connecting block 10 to apply pressure to the second spring 22. At the same time, the movement of the mounting shell 8 will drive the first rotating block 13 and the rotating column 12 to rotate on the inner wall of the fixed block 11. During the rotation, the first rotating block 13 will drive the extension rod 14 and the placement shell 15 to rotate, thereby causing the placement shell 15 to apply pressure to the first spring 16 when rotating. After being pressured, the first spring 16 will move on the inner wall of the placement shell 15. Then, the second spring 22 and the first spring 16 release their elastic potential energy, causing the first spring 16 and the second spring 22 to apply pressure to the connecting block 10. The connecting block 10 then pushes the roller 9 to apply pressure to the roller shutter body 5, thereby ensuring that the roller shutter body 5 remains stable during operation and avoiding jamming during movement.
[0025] In a preferred embodiment: an infrared monitoring device 1 2, an infrared monitoring device 2 3 and a power device 4 are fixedly mounted on the outer wall of the door frame body 1, and the power output shaft of the power device 4 is fixedly mounted on the roller shutter door body 5.
[0026] In the above structure, after infrared monitoring device 2 and infrared monitoring device 3 detect that someone is in the location, they will send a signal to the power device 4. After receiving the signal, the power device 4 will drive the roller shutter door body 5 to rotate. When the roller shutter door body 5 rotates, it will move on the inner wall of the placement groove 6, thereby opening the roller shutter door body 5.
[0027] In a preferred embodiment: the protective component 7 includes a placement block 701, a cylinder 702 is rotatably connected to the inner wall of the placement block 701, a rotating plate 703 is fixedly mounted on the outer wall of the cylinder 702, a protective plate 704 is fixedly mounted on the outer wall of the rotating plate 703, a spring 705 is fixedly mounted on the bottom of the protective plate 704, and a limiting rod 706 is provided on the inner wall of the spring 705.
[0028] In the above structure, when the roller shutter door body 5 descends, it applies pressure to the protective plate 704, causing the protective plate 704 to drive the rotating plate 703 and the cylinder 702 to rotate on the inner wall of the placement block 701 after bearing the pressure. During this process, the rotating plate 703 applies pressure to the spring 705 when rotating, causing the spring 705 to extend and retract. The limiting rod 706 limits the rotating plate 703, ensuring that the rotating plate 703 limits the roller shutter door body 5 after rotating to a specific position, thereby achieving the purpose of protecting the roller shutter door body 5.
[0029] In a preferred embodiment: the placement block 701, the spring 705, and the limiting rod 706 are all fixedly assembled with the inner wall of the placement groove 6, and the protective plate 704 is slidably connected with the inner wall of the placement groove 6.
[0030] In the above structure, the placement groove 6 is used to limit the position of the protection component 7, making the protection component 7 more stable when placed. The placement groove 6 is also used to limit the position of the protection plate 704, making the protection plate 704 more stable when moving.
[0031] In a preferred embodiment: the limiting plate 17 and the connecting rod 18 are both slidably connected to the inner wall of the placement shell 15, and the rotating block 29 is fixedly assembled to the outer wall of the rotating rod 21.
[0032] In the above structure, the shell 15 is used to limit the position of the limiting plate 17 and the connecting rod 18, making the limiting plate 17 and the connecting rod 18 more stable when moving. The rotating block 21 is used to connect the rotating rod 21 and the connecting rod 18, and also to limit the position of the connecting rod 18.
[0033] In a preferred embodiment: there are two sets of protective components 7, and the two sets of protective components 7 are respectively located on the inner wall of the placement groove 6, and the roller shutter body 5 is slidably connected to the inner wall of the placement groove 6.
[0034] In the above structure, two sets of protective components 7 are used to limit the two sides of the roller shutter body 5 to prevent damage to the roller shutter body 5 when it falls. The placement groove 6 is used to limit the roller shutter body 5 so that the roller shutter body 5 can only move within the inner wall of the placement groove 6.
[0035] Working principle: When the roller shutter body 5 moves, it applies pressure to the roller 9, causing it to exert pressure on the mounting shell 8, which in turn moves the mounting shell 8 within the inner wall of the placement groove 6. As the mounting shell 8 moves, it also exerts pressure on the connecting block 10, causing the connecting block 10 to press against the second spring 22. Simultaneously, the movement of the mounting shell 8 drives the rotating block 13 and the rotating column 12 to rotate within the inner wall of the fixed block 11. During rotation, the rotating block 13 pushes the extension rod 14 and the placement shell 15 to rotate, which in turn causes the placement shell 15 to exert pressure on the first spring 16, causing the first spring 16 to move within the inner wall of the placement shell 15. The elastic potential energy of the second spring 22 and the first spring 16 is released. Spring 16 and spring 22 together apply pressure to the mounting shell 8, which in turn pushes the roller 9 to apply pressure to the outer wall of the roller shutter body 5, ensuring the stability of the roller shutter body 5 during operation and preventing jamming during movement. When the roller shutter body 5 falls, it applies pressure to the protective plate 704, causing the protective plate 704 to push the rotating plate 703 and the cylinder 702 to rotate in the inner wall of the placement block 701. When the rotating plate 703 rotates, it applies pressure to the spring 3 705, causing it to extend and retract. The limiting rod 706 limits the rotating plate 703, ensuring that the rotating plate 703 limits the roller shutter body 5 after rotating to a specific position, thereby protecting the roller shutter body 5.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
