Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and in particular to a detachable roller assembly for high-speed roller shutters. Background Technology

[0002] High-speed rolling shutter doors are industrial-grade doors driven by motors and equipped with high-speed lifting functions. Their core functions are to quickly isolate spaces, ensure area security, and improve passage efficiency. They are widely used in factory workshops, logistics warehouses, cold chain storage facilities, clean rooms, underground garages, and other scenarios. The roller assembly of a high-speed rolling shutter door is the core component of its transmission system. It is responsible for winding and releasing the door body and driving the door body to lift and lower at high speed under the drive of the motor. There is a type of product on the market that installs a tubular motor inside the roller. In this type of roller assembly, the motor is hidden inside the roller tube. The rotation of the motor drives the transmission shaft to rotate, thereby realizing the lifting and lowering of the roller shutter slats. When rising, the slats are wound on the roller, and when descending, the slats slide down the inside of the guide rail.

[0003] In commercially available roller assemblies with built-in tubular motors, when the motor is damaged, technicians remove the mounting rivets between the motor and the roller drum to replace the motor. These roller assemblies have exposed shafts at both ends inserted into the pre-installed mounting plate of the roller shutter door box, using pins and cotter pins for installation. This installation structure is relatively simple, but it provides limited support stability during roller operation. Furthermore, disassembling the roller for maintenance requires pulling out the cotter pins at the pin positions, which requires considerable effort to reposition before removal. This makes the use and maintenance of roller assemblies for high-speed roller shutter doors inconvenient. Therefore, we propose a detachable roller assembly for high-speed roller shutter doors. Utility Model Content

[0004] The main objective of this invention is to provide a detachable roller assembly for high-speed rolling doors. This is achieved by installing a roller mounting mechanism on the roller body of the high-speed rolling door, which can be assembled into the inner panel of the rolling door. A V-shaped support block then supports the shaft head of the tubular motor and the shaft head at the other end of the roller body. A bottom groove pressing block then presses the shaft head firmly within the V-shaped support block, causing a pin at the bottom of the bottom groove pressing block to pass through the pin hole of the shaft head and be pinned to the fixed hole of the V-shaped support block. Simultaneously, a T-shaped stop post at the V-shaped support block blocks the bottom groove pressing block. The anti-detachment clamping mechanism provides stable support for the roller body and eliminates the need for the laborious installation steps of disassembling and assembling cotter pins, as is required for traditional roller shutter rollers. This simplifies the installation process of the roller body. By pressing the T-shaped stop post to retract it into the U-shaped guide plate and U-shaped tail groove, the bottom groove pressure block can be directly lifted out, allowing the roller body to be removed for disassembly and maintenance. This eliminates the need for the laborious disassembly and assembly of pins and cotter pins required for traditional roller shutter rollers, reducing the maintenance difficulty for roller shutter technicians and effectively solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A detachable roller assembly for a high-speed rolling shutter door includes a roller body and a tubular motor. The tubular motor is mounted at one end of the roller body, and extends beyond the housing of the roller body, with a shaft head having a pin hole on its surface fixed to it. The assembly also includes a shaft mounting mechanism comprising a V-shaped support block, a top cover plate, a T-shaped stop, a spring, a bottom groove pressure block, and a hole mounting plate. The shaft head is engaged with the V-shaped support block, and the opposing inner surface of the V-shaped support block has a U-shaped groove for engaging a U-shaped through plate. The V-shaped support block is located behind the U-shaped groove. The block surface has a U-shaped tail groove, and a tail limiting strip is inserted into the groove cavity. A T-shaped stop post and a spring are inserted into the U-shaped tail groove below the tail limiting strip. The T-shaped stop post, away from the spring, protrudes from the U-shaped through plate. A top cover plate installed on the top of the V-shaped support block is welded to the top of the tail limiting strip and the U-shaped through plate. A bottom groove pressure block for pressing the shaft head is inserted into the V-shaped support block below the T-shaped stop post. An insertion pin hole and a pin rod inside the V-shaped support block are welded below the bottom groove pressure block. The V-shaped support block is welded to the surface of the hole mounting plate.

[0006] Furthermore, a fixed hole is provided in the V-shaped support block below the pin hole, and a pin rod is inserted between the pin hole and the fixed hole; By adopting the above technical solution, the pin can be inserted from the pin hole of the shaft head into the fixed hole of the V-shaped support block for locking and securing.

[0007] Furthermore, the surface of the U-shaped plate is perforated, and a T-shaped stop post extends through the perforation. The diameter of the disc at the tail of the T-shaped stop post is larger than the diameter of the perforation. By adopting the above technical solution, the T-shaped stop post can pass through the perforation of the U-shaped through plate and prevent itself from completely detaching from the U-shaped through plate by its own disc body within the U-shaped groove.

[0008] Furthermore, a semi-circular groove is provided below the tail limit bar, and a spring and a T-shaped stop are inserted into the semi-circular groove of the tail limit bar. By adopting the above technical solution, the tail limit bar can press the spring and the T-shaped stop with a semi-circular groove, ensuring that the spring bounces linearly in the groove below the tail limit bar.

[0009] Furthermore, an installation hole is provided between the plate of the top cover and the block of the V-shaped support, and bolts are screwed into the installation holes of the top cover and the V-shaped support. By adopting the above technical solution, bolts can be screwed into the mounting holes of the top cover plate and the V-shaped support block for locking.

[0010] Furthermore, a bottom groove is provided below the block body of the bottom groove pressing block, and a shaft head is inserted into the bottom groove; By adopting the above technical solution, the bottom groove pressing block can press the shaft head tightly with the bottom groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a shaft mounting mechanism on the roller body of a high-speed roller shutter door. The shaft mounting mechanism can be assembled on the inner box panel of the roller shutter door. Then, a V-shaped support block supports the shaft head of the tubular motor and the shaft head at the other end of the roller body. A bottom groove pressure block presses the shaft head in the V-shaped support block, so that the pin rod under the bottom groove pressure block passes through the pin hole of the shaft head and is pinned and fixed to the fixed hole of the V-shaped support block. At the same time, a T-shaped stop block is placed above the bottom groove pressure block at the V-shaped support block to prevent detachment and press firmly, thus achieving stable support for the roller body. It also eliminates the need for the laborious installation steps of disassembling and assembling cotter pins as in traditional roller shutter door rollers, simplifying the installation steps of the roller body. Furthermore, by pressing the T-shaped stop post to retract it into the U-shaped through plate and U-shaped tail groove, the bottom groove pressure block can be directly lifted out. Then, it can be lifted away from the roller body for disassembly and maintenance. This eliminates the need for the laborious installation steps of disassembling and assembling the latch and cotter pin when replacing the roller body, as is the case with traditional roller shutter rollers, thus reducing the maintenance difficulty for roller shutter technicians.

A bottom groove pressure block 14 for pressing the shaft head 3 is inserted into the V-shaped support block 6 below the T-shaped stop post 12. A pin rod 15 for inserting into the pin hole 4 and the V-shaped support block 6 is welded below the bottom groove pressure block 14. The V-shaped support block 6 is welded to the surface of the hole mounting plate 17.

[0018] Among them, a fixed hole 16 is provided in the V-shaped support block 6 below the pin hole 4, and a pin rod 15 is inserted between the pin hole 4 and the fixed hole 16. By adopting the above technical solution, the pin rod 15 can be inserted from the pin hole 4 of the shaft head 3 into the fixed hole 16 of the V-shaped support block 6 for locking and pinning.

[0019] The U-shaped plate 10 has a through hole on its surface, and a T-shaped stop post 12 protrudes through the through hole. The diameter of the disc at the tail of the T-shaped stop post 12 is larger than the diameter of the hole. By adopting the above technical solution, the T-shaped stop post 12 can pass through the perforation of the U-shaped through plate 10, and its own disc body prevents its own post body from completely detaching from the U-shaped through plate 10 within the U-shaped groove 8.

[0020] The tail limiting strip 11 has a semi-circular groove at the bottom of its body, and a spring 13 and a T-shaped stop post 12 are inserted into the semi-circular groove of the tail limiting strip 11. By adopting the above technical solution, the tail limit bar 11 can press the spring 13 and the T-shaped stop post 12 with a semi-circular groove, ensuring that the spring 13 bounces linearly in the groove below the tail limit bar 11.

[0021] The top cover plate 7 and the V-shaped support block 6 are provided with mounting holes, and bolts are screwed into the mounting holes of the top cover plate 7 and the V-shaped support block 6. By adopting the above technical solution, bolts can be screwed into the mounting holes of the top cover plate 7 and the V-shaped support block 6 for locking.
