Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter door accessories, in particular to a novel rolling shutter door roller structure. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. In a fixed slide, the door rotates up and down with the roller above the door as the center. Rolling shutter doors are usually widely used in shops and play the role of horizontal partition like walls. It consists of curtain plates, seat plates, guide rails, supports, rollers, boxes, control boxes, rolling door machines, limiters, lintels, manual quick-release switch devices, push button switches and safety devices. It is usually installed in places where it is inconvenient to use walls for partitions. The rollers can bear the weight of the rolling shutter door.

[0003] After searching, a Chinese patent with announcement number CN209875017U discloses a roller for a garage rolling door. The roller needs to contact, collide and vibrate with other components, which brings about uninterrupted noise and produces great noise pollution. Therefore, the contact between the elastic ring and other components helps to reduce the noise caused by the collision, and the holes and grooves help to strengthen the connection between the elastic ring and the wheel body. The entire roller structure is reasonably designed, easy to use, and has excellent effect in reducing noise.

[0004] There are still some shortcomings in the use of the above-mentioned rolling door roller structure. When installing the rolling door roller, it is usually necessary to screw multiple bolts and nuts to install the roller. When the roller is disassembled and replaced after a long period of use, it is necessary to re-tighten the multiple nuts and bolts to disassemble the roller, making the disassembly and assembly process more laborious and troublesome, thereby reducing the disassembly and assembly efficiency, easily delaying working time, and making it inconvenient for maintenance and replacement.

The inner side of the mounting groove 8 is fixedly connected with a push spring 9, and the other end of the push spring 9 is fixedly connected with a push block 10, which is convenient for improving the fastening effect of the installed rolling wheel 13. A threaded groove 11 is provided on the left side of the fixed block 6, and a threaded cover 12 is threadedly connected to the outer side of the threaded groove 11 to facilitate the limiting effect. A sliding rod 23 is fixedly connected to the rear side of the rotating block 7, and the outer side of the sliding rod 23 is slidably connected with the rolling wheel 13, which improves the stability of the installation of the rolling wheel 13.

[0032] The front side of the mounting shell 1 is fixedly connected with an adjusting rod 14 for adjusting the position of the rolling wheel 13. Slide grooves 15 are provided on the left and right sides of the adjusting rod 14. Slide blocks 16 are slidably connected to the inner sides of the slide grooves 15. Fixed shells 17 are fixedly connected to the opposite sides of the slide blocks 16 on the left and right sides, which improve the stability of the adjusting rod 14 sliding inside the fixed shell 17. A threaded hole 18 is provided on the top of the front side of the fixed shell 17 for installing a screw 19. The inner side of the threaded hole 18 is threadedly connected with the screw 19 for fixing the adjusting rod 14. A stabilizing groove 20 is provided on the front side of the adjusting rod 14. A mounting block 21 is fixedly connected to the right side of the fixed shell 17 for mounting the roller as a whole. A pull ring 22 is fixedly connected to the other end of the pull rod 4 for pulling the pull rod 4. The other end of the fastening spring 5 is fixedly connected to the inner right side of the sleeve 2, which improves the stability of the fastening spring 5.
