Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller shutter door technology with high stability, specifically a roller shutter door with high stability. Background Technology
[0002] As is well known, a roller shutter door is a door with multiple articulated door panels linked together, rotating up and down around a central roller within fixed tracks. Roller shutter doors are widely used in shops, serving the same function as walls for horizontal partitioning. They consist of multiple parts, including curtain panels, base plate, guide rails, supports, roller, housing, control box, roller motor, limit switches, lintel, manual quick-release switch, push-button switch, and safety devices. They are typically installed in locations where walls are inconvenient for partitioning.
[0003] Existing roller shutter door frames cause wear and tear due to friction between the roller shutter door and the frame during operation. After prolonged use, the roller shutter door is prone to deformation and noise during operation. Therefore, we propose a roller shutter door with high stability to solve the above problems.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3This utility model discloses a highly stable roller shutter door, comprising a roller shutter door retraction frame 1, a roller shutter door storage box 2 at the top of the roller shutter door retraction frame 1, and a roller shutter door panel 3 at the bottom of the roller shutter door storage box 2. Several sliding grooves 4 are provided on the left and right sides of the roller shutter door retraction frame 1, each sliding groove 4 being a stepped groove, facilitating the adjustment of sliding step blocks 5 in the sliding grooves 4 of this highly stable roller shutter door. Several sliding step blocks 5 are provided at the front and rear of each sliding groove 4, each sliding step block 5 cooperating with the sliding groove 4 in a sliding fit, allowing the sliding step block 5 to slide along the sliding groove 4 for adjustment. A telescopic spring is provided in the middle of each sliding step block 5. 6. Each sliding step block 5 is provided with a sliding ball groove 7, and each sliding ball groove 7 is provided with a sliding ball block 8 in the middle. Each sliding ball block 8 cooperates with the sliding ball groove 7. The cooperation between each sliding ball block 8 and the sliding ball groove 7 is a sliding cooperation, so that the sliding ball block 8 can slide and adjust along the sliding ball groove 7. The edges of the roller shutter door retraction frame 1, roller shutter door storage box 2, roller shutter door panel 3, sliding through groove 4, sliding step block 5, telescopic spring 6, sliding ball groove 7 and sliding ball block 8 are all set with rounded corners, so that the highly stable roller shutter door will not scratch the user during use. The highly stable roller shutter door can prevent the roller shutter door from rubbing against the retraction frame when the roller shutter door is retracted, so that it will not be worn. After long-term use, the roller shutter door is not easy to deform.
[0022] In summary, this highly stable roller shutter door allows for adjustment of the roller shutter door panel 3. The sliding step block 5 can be adjusted via the telescopic spring 6, allowing several sliding ball blocks 8 to engage with the roller shutter door panel 3. The sliding engagement between each sliding ball block 8 and the sliding ball groove 7 assists in the sliding and retracting of the roller shutter door panel 3. Since the sliding step block 5 can be adjusted at any angle within the sliding ball groove 7, it will not experience any friction or damping during the sliding and retracting process, thus avoiding friction with the roller shutter door retraction frame 1. This highly stable roller shutter door prevents friction between the roller shutter door and the retraction frame during operation, preventing wear and tear. Furthermore, the roller shutter door is less prone to deformation after prolonged use, resulting in a better overall performance.
