Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, specifically to an anti-jamming roller shutter door. Background Technology

[0002] Anti-jamming roller shutters typically use high-strength, high-toughness materials for their slats and guide rails, such as aluminum alloy and galvanized steel plates. These materials are not only sturdy and durable, but also effectively resist deformation caused by external forces. Furthermore, existing roller shutter systems can regularly clean the dust and debris inside the unloading frame to keep the slats clean and prevent dust accumulation from affecting the operation of the roller shutter and causing jamming.

[0003] The existing technology has the following problems:

[0004] The existing system does not allow for the removal of the rewind rack cover during use. Some internal components, such as bearings and gears, may experience wear, aging, or damage after prolonged use. Without removing the cover, the condition of these components cannot be directly observed, making it difficult to detect problems and perform timely repairs or replacements. This can lead to the accumulation of hidden dangers, ultimately affecting the normal operation of the roller shutter and increasing the risk of jamming or even complete malfunction due to component failure. Furthermore, the existing system does not allow for dust removal and cleaning of the rewind rack's interior. Dust and debris accumulate inside, forming a thick layer of grime between components. When the roller shutter is running, this grime increases frictional resistance, accelerating the wear of bearings, gears, and other components. Due to the increased frictional resistance, the roller shutter requires more power to overcome this resistance during operation. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1As shown, this utility model provides an anti-jamming roller shutter door, including a fixed frame 1, a track 2 fixedly connected to the front side of the fixed frame 1, a winding frame 3 fixedly connected to the upper front end of the fixed frame 1, a first motor 6 fixedly connected to the right side of the winding frame 3, a winding frame cover plate 4 movably connected to the front side of the winding frame 3, a locking mechanism 5 provided inside the winding frame cover plate 4, a fan 7 fixedly connected to the left side of the winding frame 3, the input pipe of the fan 7 being fixedly connected through the winding frame 3, a curtain slat 8 being slidably connected through the lower side of the winding frame 3, the outer wall of the curtain slat 8 being slidably connected to the track 2, and two slots 9 being provided on the front side of the winding frame 3. The fixed frame 1 is used to fix the entire roller shutter door device. The track 2 provides guidance for the up and down sliding of the curtain 8. The rewinding frame 3 is used to install and accommodate the rewinding components of the roller shutter door. The first motor 6 provides power for the rotation of the rewinding roller 11, thereby realizing the rewinding and unwinding of the curtain 8. The rewinding frame cover 4 is connected to the rewinding frame 3 through the locking mechanism 5, which facilitates the opening and closing of the rewinding frame 3. The fan 7 can vacuum and clean the inside of the rewinding frame 3 to keep it clean and reduce the risk of jamming. The curtain 8 slides in the track 2 to realize the opening and closing function of the roller shutter door. The slot 9 is used to lock and unlock the rewinding frame cover 4 in conjunction with the locking mechanism 5.

[0024] like Figure 2-3 As shown, this utility model provides a technical solution: Preferably, the locking mechanism 5 includes a knob 55, a worm gear 56 fixedly connected to the rear side of the knob 55, a worm wheel 57 meshing with the outer wall of the worm gear 56, a threaded rod 58 fixedly connected through the left side of the worm wheel 57, two movable blocks 51 threadedly connected to the outer wall of the threaded rod 58, two connecting plates 53 rotatably connected to the upper and lower sides of the movable blocks 51, an insert block 52 rotatably connected to the other end of the connecting plate 53, the outer wall of the insert block 52 movably connected to the slot 9, a limit rod 54 fixedly connected to the inner wall of the winding rack cover plate 4, the outer wall of the limit rod 54 slidably connected to the movable block 51, the outer wall of the insert block 52 slidably connected to the winding rack cover plate 4, and the threads at the left and right ends of the outer wall of the threaded rod 58 having opposite directions. When it is necessary to disassemble the take-up rack cover 4, turn the knob 55. The knob 55 drives the worm 56 to rotate. The worm 56 meshes with the worm wheel 57, thereby driving the worm wheel 57 to rotate. When the worm wheel 57 rotates, the threaded rod 58 fixed on its left side rotates accordingly. Since the threads at the left and right ends of the outer wall of the threaded rod 58 are opposite, the two movable blocks 51 will move in opposite directions on the threaded rod 58. When the movable blocks 51 move, they drive the insert block 52 to move through the connecting plate 53, so that the insert block 52 is pulled out from the slot 9, thereby unlocking the take-up rack cover 4, which facilitates the disassembly of the take-up rack cover 4 and the inspection of the internal components of the take-up rack 3. The limit rod 54 limits the movable block 51, ensuring that the movable block 51 can only move in the axial direction of the threaded rod 58.

[0025] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a dustproof plate 12 is provided on the upper side of the winding frame 3, a fixing block 14 is fixedly connected to the upper side of the winding frame 3, a second motor 15 is fixedly connected to the left side of the fixing block 14, a drive shaft 10 is fixedly connected to the output end of the first motor 6, a winding roller 11 is fixedly connected to the outer wall of the drive shaft 10, the outer wall of the winding roller 11 is fixedly connected to the curtain slat 8, a gear 16 is fixedly connected to the output shaft of the second motor 15, a rack 18 is meshed with the outer wall of the gear 16, a support plate 17 is fixedly connected to the rear side of the rack 18, a lifting plate 20 is fixedly connected to the lower end of the support plate 17, a limit post 19 is fixedly connected to the lower side of the inner wall of the fixing block 14, the outer wall of the limit post 19 is slidably connected to the lifting plate 20, and the lifting plate... Two inserts 21 are fixedly connected to the lower side of the dustproof plate 12, and two holes 13 are opened on the upper side of the dustproof plate 12. The outer wall of the insert 21 is movably connected to the hole 13, and the outer wall of the insert 21 is slidably connected to the fixing block 14. When the dustproof plate 12 needs to be disassembled and replaced, the second motor 15 can be started. The output shaft of the second motor 15 drives the gear 16 to rotate. The gear 16 meshes with the rack 18, so that the rack 18 moves up and down under the action of the gear 16. When the rack 18 moves, it drives the lifting plate 20 to slide on the limit post 19 through the support plate 17. When the lifting plate 20 moves down, the insert 21 is pulled out from the hole 13, so that the dustproof plate 12 can be disassembled. Then the fan 7 is turned on to clean the dust inside the winding frame 3 and keep the inside clean.

[0026] The working principle of this anti-jamming roller shutter door will be explained in detail below.

[0027] like Figure 1-5 As shown, when it is necessary to remove the take-up rack cover 4, turn the knob 55. The knob 55 drives the worm gear 56 to rotate. The worm gear 56 meshes with the worm wheel 57, thereby driving the worm wheel 57 to rotate. When the worm wheel 57 rotates, the threaded rod 58 fixed on its left side rotates accordingly. Since the threads at the left and right ends of the outer wall of the threaded rod 58 are opposite, the two movable blocks 51 will move in opposite directions on the threaded rod 58. When the movable blocks 51 move, they drive the insert block 52 to move through the connecting plate 53, causing the insert block 52 to be pulled out of the slot 9, thereby unlocking the take-up rack cover 4, facilitating the removal of the take-up rack cover 4, and then inspecting the internal components of the take-up rack 3. Limit rod 54 The movable block 51 is limited to ensure that it can only move axially along the threaded rod 58. When the dust cover 12 needs to be disassembled and replaced, the second motor 15 can be started. The output shaft of the second motor 15 drives the gear 16 to rotate. The gear 16 meshes with the rack 18, causing the rack 18 to move up and down under the action of the gear 16. When the rack 18 moves, it drives the lifting plate 20 to slide on the limit post 19 through the support plate 17. When the lifting plate 20 moves downward, the insertion post 21 is pulled out from the insertion hole 13, so that the dust cover 12 can be disassembled. Then, the fan 7 is turned on to vacuum and clean the inside of the winding frame 3 to keep the inside clean.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
