Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, specifically a roller shutter door assembly track structure. Background Technology

[0002] Roller shutters consist of multiple articulated door panels linked together within fixed tracks. The door rotates up and down around a central roller at the top, raising or lowering the slats to open and close the door. Roller shutters are a common choice in commercial, industrial, and residential building renovations, offering not only an aesthetically pleasing appearance but also sound insulation and security features. While existing roller shutters incorporate guide wheels to reduce direct friction between the slats and the track, thus mitigating track wear to some extent, the slats still cannot maintain perfect vertical alignment within the track, leading to wobbling and gaps between the slats and the door frame. Utility Model Content

[0003] The purpose of this utility model is to provide an assembly track structure for roller shutter doors to solve the problems raised in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A roller shutter door assembly track structure includes a roller shutter door storage compartment, a support frame, a guide rail, a roller shutter door slat, slat guide wheels, and a slat alignment disc. The inner wall of the roller shutter door storage compartment is provided with a rotatably connected winding shaft. One end of the roller shutter door slat is fixed to the outer wall of the winding shaft, and the other end of the roller shutter door slat extends to the outside of the roller shutter door storage compartment. The roller shutter door storage compartment is used to store the roller shutter door slat. Support frames are fixedly connected to both sides of the roller shutter door storage compartment. A guide rail is provided on the outer wall of the support frame near the roller shutter door slat, and a rotatably connected slat guide wheel is provided at the bottom of the roller shutter door slat. The slat guide wheel matches the guide rail and slides along the trajectory of the guide rail. The slat alignment disc is rotatably connected between the roller shutter door slat and the slat guide wheel. A spring is provided between the slat alignment disc and the slat guide wheel.

[0006] The roller shutter door's storage compartment is used to store the roller shutter door slats, and the support frames on both sides of the storage compartment are used to fix the guide rails. The roller shutter door's guide wheels slide along the guide rails to ensure that the slats remain in the correct position. The slat self-aligning disc is connected to the slat guide wheels via springs to automatically adjust the position of the slats.

[0007] Furthermore, a rubber buffer layer is affixed to the inner wall of the roller shutter compartment.

[0008] The inner wall of the roller shutter compartment is lined with a rubber buffer layer, which reduces the collision and friction between the roller shutter slats and the inner wall of the roller shutter compartment. This avoids vibration and noise caused by direct contact between the roller shutter slats and the inner wall of the roller shutter compartment. At the same time, the rubber buffer layer increases the friction between the roller shutter slats and the inner wall of the roller shutter compartment, preventing the roller shutter slats from shaking and loosening inside the roller shutter compartment.

[0009] Furthermore, the surface of the roller shutter slats is coated with a nano-coating material.

[0010] The surface of the roller shutter slats is coated with a nano-coating material, which has an extremely low coefficient of friction. This reduces friction between the roller shutter slats and the guide rails, as well as between roller shutter slats themselves, thereby reducing wear on the roller shutter slats and the guide rails.

[0011] Furthermore, the guide rail is fixedly installed on the support frame by snap-fit.

[0012] The snap-fit ​​connection between the guide rail and the support frame ensures that the guide rail is accurately installed in the predetermined position on the support frame, guaranteeing the accurate relative position between the guide rail and the curtain guide wheel, thus improving installation efficiency.

[0013] Furthermore, the roller shutter slats, the slat guide wheels, and the slat alignment disc are rotatably connected by a connecting shaft, and the slat guide wheels and the slat alignment disc are fixedly connected by a spring.

[0014] The connecting shaft allows the roller shutter slats and the slat guide wheels to rotate relative to each other. During the opening and closing of the roller shutter, the roller shutter slats move vertically along the guide rail. The function of the slat centering disc is to automatically adjust the position of the slats during the movement of the slats, so that they always maintain good contact with the guide rail.

[0015] Furthermore, a permanent magnet strip is embedded in the guide track, and magnetic tape is pasted on the inner wall of the groove of the curtain guide wheel, while rubber anti-slip tape is provided on the outer wall of the curtain guide wheel.

[0016] The permanent magnet strips inside the guide track and the magnetic tape on the inner wall of the groove of the curtain guide wheel attract each other, allowing the magnetic force to assist the guide wheel in rolling in the track, reducing the gap and bounce between the guide wheel and the track, making the movement of the curtain more stable, and further reducing the swaying and friction of the curtain during operation.

[0017] Furthermore, both guide tracks are fixed with guide wheel limiters, which are used to limit the movement of the curtain guide wheels.

[0018] One of the main functions of the guide wheel limiter is to limit the lateral and longitudinal displacement of the guide wheel, so that it always moves in the correct track position. By precisely limiting the guide wheel of each slat, all slats can maintain a relatively parallel state during movement.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a rotatably connected curtain guide wheel and curtain self-aligning disc at the bottom of the roller shutter door, the roller shutter door maintains the vertical movement of the curtain during operation and automatically adjusts the longitudinal position of the curtain, making the roller shutter door run smoothly and with accurate positioning, reducing the swaying of the roller shutter door curtain and the friction between the roller shutter door curtain and the guide rail, and improving the performance and service life of the roller shutter door.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] like Figure 1-4As shown, a roller shutter door assembly track structure includes a roller shutter door storage compartment 1, a support frame 2, a guide track 3, a roller shutter door slat 4, slat guide wheels 5, and a slat alignment disc 6. The inner wall of the roller shutter door storage compartment 1 is provided with a rotatably connected winding shaft 10. One end of the roller shutter door slat 4 is fixed to the outer wall of the winding shaft 10, and the other end of the roller shutter door slat 4 extends to the outside of the roller shutter door storage compartment 1. The roller shutter door storage compartment 1 is used to store the roller shutter door slat 4. Both sides of the roller shutter door storage compartment 1 are fixed... A support frame 2 is fixedly connected. A guide rail 3 is provided on the outer wall of the support frame 2 near the side of the roller shutter slat 4. A rotatably connected slat guide wheel 5 is provided at the bottom of the roller shutter slat 4. The slat guide wheel 5 matches the guide rail 3 and slides along the trajectory of the guide rail 3. A slat alignment disc 6 is rotatably connected between the roller shutter slat 4 and the slat guide wheel 5. A spring 11 is provided between the slat alignment disc 6 and the slat guide wheel 5.

[0028] The roller shutter door storage compartment 1 is used to store the roller shutter door slats 4. The support frames 2 on both sides of the roller shutter door storage compartment 1 are used to fix the guide rails 3. The roller shutter door guide wheels slide along the trajectory of the guide rails 3 to ensure that the slats are kept in the correct position. The slat self-aligning disc 6 is connected to the slat guide wheels 5 through springs 11 to automatically adjust the position of the slats.

[0029] like Figure 2 As shown, a rubber buffer layer 15 is attached to the inner wall of the roller shutter door hopper 1, which reduces the collision and friction between the roller shutter door slats 4 and the inner wall of the roller shutter door hopper 1, and avoids the vibration and noise caused by direct contact between the roller shutter door slats 4 and the inner wall of the roller shutter door hopper 1. At the same time, the rubber buffer layer 15 increases the friction between the roller shutter door slats 4 and the inner wall of the roller shutter door hopper 1, preventing the roller shutter door slats 4 from shaking and loosening inside the roller shutter door hopper 1.

[0030] The surface of the roller shutter slat 4 is coated with a nano-coating material. The nano-coating material has an extremely low coefficient of surface friction, which is used to reduce the friction between the roller shutter slat 4 and the guide rail 3, as well as between the roller shutter slat 4 and the roller shutter slat 4, thereby reducing the wear of the roller shutter slat 4 and the guide rail 3.

[0031] like Figure 2 As shown, the guide rail 3 is fixedly installed on the support frame 2 by a snap fastener.

[0032] The snap-fit ​​connection between the guide rail 3 and the support frame 2 ensures that the guide rail 3 is accurately installed in the predetermined position of the support frame 2, and guarantees that the relative position between the guide rail 3 and the curtain guide wheel 5 is accurate, thus improving installation efficiency.

[0033] like Figure 3-4As shown, the roller shutter slat 4, slat guide wheel 5, and slat adjusting disc 6 are rotatably connected by the connecting shaft 12, and the slat guide wheel 5 and slat adjusting disc 6 are fixedly connected by the spring 11.

[0034] The connecting shaft 12 enables the roller shutter slats 4 and the slat guide wheel 5 to rotate relative to each other. During the opening and closing of the roller shutter, the roller shutter slats 4 move vertically along the guide rail 3. The function of the slat centering disc 6 is to automatically adjust the position of the slats during the movement of the slats, so that they always maintain good contact with the guide rail 3.

[0035] like Figure 2 As shown, a permanent magnet strip 17 is embedded in the guide track 3, and magnetic tape 18 is pasted on the inner wall of the groove of the curtain guide wheel 5, and rubber anti-slip tape is provided on the outer wall of the curtain guide wheel 5.

[0036] The permanent magnet strip 17 inside the guide track 3 and the magnetic tape 18 on the inner wall of the groove of the curtain guide wheel 5 attract each other, allowing the magnetically assisted guide wheel to roll in the track, reducing the gap and bounce between the guide wheel and the track, making the movement of the curtain more stable, and further reducing the swaying and friction of the curtain during operation.

[0037] like Figure 3 As shown, both guide rails 3 are fixed with guide wheel limiters, which are used to limit the movement of the curtain guide wheel 5.

[0038] One of the main functions of the guide wheel limiter is to limit the lateral and longitudinal displacement of the guide wheel, so that it always moves in the correct track position. By precisely limiting the guide wheel 5 of each slat, all slats can maintain a relatively parallel state during the movement.

[0039] The working principle of this utility model is as follows: When the roller shutter door is descending, the winding shaft 10 on the inner wall of the roller shutter door's roller compartment 1 begins to rotate. One end of the roller shutter door slat 4 is fixedly connected to the winding shaft 10, and the other end of the roller shutter door slat 4 begins to descend. The curtain guide wheel 5 at the bottom of the roller shutter door slat 4 moves along the guide rail 3 to ensure the stable vertical movement of the roller shutter door slat 4. The curtain self-aligning disc 6 automatically adjusts the horizontal position of the roller shutter door slat 4 according to the elastic restoring force of the spring 11 to ensure that the roller shutter door slat 4 is always tightly fitted to the door frame, reducing shaking and friction. When the curtain guide wheel 5 moves to the guide wheel limiter, the curtain guide wheel 5 stops moving to prevent the roller shutter door slat 4 from descending excessively and avoid collision between the roller shutter door slat 4 and the ground.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
