TECHNICAL FIELD

[0001] The utility model relates to slide rail device technical field especially relates to a roller shutter door slide structure. BACKGROUND

[0002] The roller shutter door (also called the rolling shutter door) is a kind of door that is formed by a plurality of jointed door leaves, and can rotate up and down in a fixed slide rail with the roller shaft on the door as the pivot.

[0003] The roller shutter door is composed of a plurality of components, including a curtain plate, a seat plate, a guide rail, a support, a roller shaft, a box body, a control box, a roller door machine, a position limiter, a lintel, a manual speed release switch device, a button switch and a safety device, etc. It is usually installed in a position where wall partition is not suitable, and the roller shutter door needs to slide in a suitable slide rail.

[0004] Specifically, the projection of the slide rail in the horizontal direction is a U-shaped structure, and the door leaf of the roller shutter door is embedded in the U-shaped opening of the slide rail, and the sliding mechanism is used to constrain the position of the roller shutter door. In practical application, it is worth noting that the width of the inner cavity of the slide rail is usually designed to be much larger than the width of the door leaf of the roller shutter door, so as to facilitate operation. Therefore, the roller shutter door can move back and forth in the slide rail. Therefore, when encountering strong wind or external force impact, the roller shutter door hitting the slide rail will not only cause the deformation of the roller shutter door, but also produce a large noise.

[0005] In view of this, the inner part of the slide rail of some roller shutter doors has been provided with corresponding rollers, which are usually arranged in two rows in a single slide rail to form a clamping effect on the roller shutter door and reduce the resistance of the roller shutter door during winding. In practical application, the size of a single roller is difficult to accurately determine. If the diameter of the roller is too small, it is easy to be stuck in the joint gap of the door leaf, and if the diameter is too large, the width of the slide rail needs to be increased accordingly, which not only damages the appearance, but also is easy to be damaged by external force, reducing the use efficiency.

[0006] Based on the above analysis, it is necessary to develop a new type of roller shutter door slide rail structure, which can effectively avoid the noise caused by the rollers embedded between the door leaves of the roller shutter door, and avoid the increase of the overall width of the slide rail.

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0023] In the description of the utility model, it is understood that the terms such as 'up', 'down', 'front', 'back' and the like are all based on the orientation shown in the drawing, which is intended to simplify the description and facilitate understanding, and does not mean that the device or element must be constructed or operated in this orientation, so it does not constitute a limitation on the utility model.

[0024] Please refer toFigure 1 A roller shutter door slide rail structure, which is consistent with the prior art device, comprises a slide rail 2 structure, the projection of which on the horizontal plane presents a U-shaped structural feature. This design not only ensures the stability of the structure, but also gives it visual aesthetics.

[0025] The roller shutter door 3 leaf is ingeniously embedded in the slide rail 2, and with the guidance and constraint of the slide rail 2, it effectively prevents the leaf from shaking and deforming. This design makes the roller shutter door 3 more stable during use, and also improves its service life.

[0026] Please refer to Figure 1 , Figure 2 The difference from the prior art device is that the slide rail 2 has multiple mounting plates 1 inside, which are embedded in the U-shaped opening of the slide rail 2, and these mounting plates 1 are arranged equidistantly in the vertical direction and are arranged from top to bottom. This design makes the structure of the slide rail 2 more compact, and also improves its carrying capacity.

[0027] At the same time, the projection of the mounting plate 1 on the horizontal plane also presents a U-shaped structure, and its U-shaped opening is consistent with the direction of the U-shaped opening of the slide rail 2, ensuring that the leaf can be smoothly embedded in both, thereby implementing stronger position constraint on the leaf through the U-shaped opening of the mounting plate 1. This design not only improves the stability of the leaf, but also improves its service life.

[0028] In addition, as shown in Figure 2 , Figure 3 A front and rear axial contact roller 8 is embedded in the U-shaped opening of each mounting plate 1, and the contact roller 8 is connected to the mounting plate 1 through a pivot 12 and can freely rotate around the pivot 12. This design makes the roller shutter door 3 more flexible during use, and also improves its service life.

[0029] Therefore, the device ingeniously sets coaxial receiving grooves 9 in the middle of each contact roller 8, and the openings of these receiving grooves 9 are designed on the side away from the pivot 12. Therefore, by constraining the width of the receiving groove 9 to be no greater than the width of the leaf of the roller shutter door 3, the leaf of the roller shutter door 3 can be smoothly embedded in the receiving groove 9. This design not only further reduces the front and rear movement range of the leaf of the roller shutter door 3, but also avoids direct hard friction between the device and the leaf of the roller shutter door 3, thereby causing damage to the leaf of the roller shutter door 3 and causing loud noise. This design makes the roller shutter door 3 safer during use, and also improves its service life.

[0030] Further, as shown in Figure 4 , Figure 5As shown, the device restricts the contact roller 8 to include a front and rear axial center shaft 802, which is rotationally connected to the mounting plate 1 through the pivot 12. This design not only enhances the stability of the roller shutter door 3, but also significantly prolongs its service life.

[0031] At the same time, the two ends of the center shaft 802 are respectively sleeved with a limiting wheel 803, and the gap between the two limiting wheels 803 constitutes an accommodating groove 9, which not only ensures the stability of the contact roller 8, but also provides sufficient accommodation space for the door leaf of the roller shutter door 3. Moreover, the design utilizes the sliding connection of the limiting wheel 803 and the center shaft 802 to enable the width of the accommodating groove 9 to be adaptively adjusted according to the width of the door leaf of the roller shutter door 3, fully considering the complexity of the environment in which the roller shutter door 3 is arranged and its deformable structural characteristics, ensuring that the door leaf can work stably even in the case of deformation. This design gives the roller shutter door 3 higher flexibility and effectively improves its durability.

[0032] Specifically, the center shaft 802 and the limiting wheel 803 are both made of plastic material, which not only ensures the lightness of the device, but also endows it with wear-resistant and corrosion-resistant properties. This design makes the roller shutter door 3 more stable during use, and also improves its service life.

[0033] At the same time, in order to further improve the stability and durability of the contact roller 8, the two limiting wheels 803 near the ends are respectively fixedly connected with elastic pads 801 made of rubber material. Such elastic pads 801 can effectively absorb and buffer vibration energy, reduce vibration transmission, and thus reduce noise generation, by virtue of their good elasticity and damping performance. This design makes the roller shutter door 3 more quiet during use, and also improves its service life.

[0034] Further, in order to facilitate the connection between the contact roller 8 and the mounting plate 1, the restraining pivot 12 of the device is designed as a bolt structure, and the screw tail part is fixed by screwing the locking nut 7. At this time, the mounting plate 1 outside restricts the screw head and locking nut 7 of each pivot 12, making it easy for the operator to install and disassemble the contact roller 8. Moreover, this design optimizes the overall structure, making it more compact, facilitating subsequent maintenance and component replacement. This design makes the roller shutter door 3 more convenient during use, and also improves its service life.

[0035] Therefore, the device is provided with an elastic gasket I 10 at the distal end of each limiting wheel 803, which enables the two limiting wheels 803 to have a tendency to move relative to each other, ensuring that the limiting wheel 803 can always abut against the door leaf of the roller shutter door 3, and also enabling the limiting wheel 803 to change position relative to the center shaft 802, achieving the technical effect of adapting the limiting wheel 803 to the door leaf of the roller shutter door 3. This design makes the roller shutter door 3 more flexible during use, and also improves its service life.

[0036] Notably, when the elastic gasket I 10 is not affected by external forces, the width between the two elastic pads 801 is less than the width of the door leaf of the roller shutter door 3, which can fully exert the clamping effect of the limiting wheel 803 on the door leaf of the roller shutter door 3 and the sound absorption and noise reduction effect of the elastic pad 801. This design makes the roller shutter door 3 more secure during use, and also improves its service life.

[0037] Similarly, in order to simplify the disassembly and maintenance process of the mounting plate 1, the device is provided with a through hole I at the upper and lower ends of each mounting plate 1, which matches the through hole II on the sliding rail 2. This design makes the roller shutter door 3 more convenient to use, and also improves its service life.

[0038] The through hole I and the through hole II are jointly inserted with a screw rod 6, and the screw tail part of the screw rod 6 is screwed with a fixed nut 4. This design uses the cooperation of the screw rod 6 and the fixed nut 4 to stably fix the mounting plate 1 on the sliding rail 2, thereby ensuring the stability of the roller shutter door 3 during use and effectively prolonging its service life.

[0039] Furthermore, in order to ensure that the center shaft 802 can abut against the side edge of the door leaf of the roller shutter door 3, and to avoid hard collision between the center shaft 802 and the deformed side edge of the roller shutter door 3, the device is provided with an elastic gasket II 5 between each mounting plate 1 and the inner wall of the sliding rail 2, which is sleeved on the outer side of the screw rod 6. The elastic gasket 801 has the function of absorbing installation errors, can ensure the smooth operation of the sliding rail 2 structure, and further improve the overall service life. This design makes the roller shutter door 3 more stable during use, and also improves its service life.

[0040] In practical application, the utility model has the advantages that:

[0041] Through the innovative structure design of the U-shaped sliding rail 2 and the mounting plate 1, and the ingenious matching of the contact roller 8 and the accommodating groove 9, the device significantly enhances the stability of the roller shutter door 3 and effectively prolongs its service life. At the same time, by selecting appropriate materials and design details, such as the use of plastic and rubber, the design of the pivot 12 of the bolt structure, and the use of the elastic gasket I 10 and the elastic gasket II 5, the performance and safety of the device are further enhanced. Overall, this design not only improves the use experience of the roller shutter door 3, but also takes into account the convenience of maintenance and replacement of parts.

[0042] Although specific embodiments of the utility model have been shown and described, those skilled in the art should understand that various forms of adjustment, modification, substitution and deformation can be made to these embodiments without departing from the basic principles and core spirit of the utility model, and the protection scope of the utility model shall be subject to the appended claims and their equivalent contents.
