Description

Technical Field

[0001] This utility model belongs to the field of roller shutter door technology, and in particular relates to an auxiliary roller for roller shutter doors. Background Technology

[0002] A roller shutter door is a door structure consisting of multiple articulated door panels linked together, rotating up and down within a fixed track around a central roller at the top of the door. Its main structural components include three parts: the curtain panels, the roller, and the guide rails. The roller is located at the top of the door and is responsible for raising and lowering the curtain panels; it can be driven by a motor or a manual device. The guide rails are metal tracks installed on both sides of the door opening to ensure the stability of the curtain panels when they are raised and lowered vertically.

[0003] During the closing of a roller shutter door, i.e., the slats descend, the angle at which the slats extend into the top of the guide rail is not always perpendicular. As the roller rotates and lowers the slats, the thickness of the slats rolled up by the roller decreases, and the angle at which the slats enter the top of the guide rail becomes increasingly inclined. This often results in the slats getting stuck and the shutter not retracting smoothly. Therefore, this invention provides an auxiliary roller for roller shutter doors to solve the above problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides an auxiliary roller for roller shutter doors.

[0005] The technical solution of this utility model is as follows: an auxiliary roller for a roller shutter door, the roller shutter door including a housing, a roller, a curtain panel, and a guide rail, the roller is provided inside the housing, the roller is used to roll up and down the curtain panel, the curtain panel can slide in the guide rail, the auxiliary roller is provided between the roller and the guide rail, it is located diagonally below the roller and diagonally above the guide rail; the auxiliary roller is octagonal in shape.

[0006] Furthermore, the auxiliary scroll is hollow inside, and each end is provided with a tail plug, which can be snapped into the end of the auxiliary scroll.

[0007] Furthermore, one end of the tail plug is snapped into the end of the auxiliary reel, and the other end is provided with a bracket plate, which is movably connected to the tail plug.

[0008] Furthermore, the two support plates are respectively fixed to the two end faces at both ends of the box cover.

[0009] Furthermore, the shape of the aforementioned auxiliary scroll can be set to circular.

[0010] The beneficial effects of this utility model are: 1. In the design scheme of this utility model, the auxiliary roller is set between the guide rail and the roller. It can support the curtain panel during the lowering process of the curtain panel. As the curtain panel is lowered, it is passively rotated to ensure that the angle of the curtain panel entering the guide rail does not change, and further ensures the smoothness of the curtain panel lifting process. 2. In the design scheme of this utility model, the auxiliary roller structure is simple, has low production cost, and is easy to install without increasing the overall installation difficulty of the roller shutter door.

[0013] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the present invention or its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0014] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0015] like Figure 1-4As shown, an auxiliary roller shaft for a roller shutter door is provided. The roller shutter door includes a housing 1, a roller 2, a curtain panel 3, and a guide rail 4. The roller 2 is installed inside the housing 1 and is used to raise and lower the curtain panel 3. The curtain panel 3 can slide within the guide rail 4. The auxiliary roller shaft 5 is located between the roller 2 and the guide rail 4, and is located diagonally below the roller 2 and diagonally above the guide rail 4. The auxiliary roller shaft 5 is octagonal in shape.

[0016] Specifically, the auxiliary scroll 5 is hollow inside, and each end of it is provided with a tail plug 501, which can be snapped into the end of the auxiliary scroll 5.

[0017] Specifically, one end of the tail plug 501 is snapped into the end of the auxiliary scroll 5, and the other end is provided with a bracket plate 502, which is movably connected to the tail plug 501.

[0018] Specifically, the two support plates 502 are fixed to the two end faces at both ends of the box cover 1.

[0019] Specifically, the shape of the aforementioned auxiliary scroll 5 can be set to circular.

[0020] like Figure 4 As shown, the auxiliary roller 5 is installed between the roller 2 and the guide rail 4. The curtain panel 3 rolled on the roller 2 will pass over the auxiliary roller 5 whether it is being rolled up or unrolled. The two ends of the auxiliary roller 5 are movably connected, and it can be passively rotated as the curtain panel 3 rises or falls. During the winding and unwinding process, the auxiliary roller 5 can ensure that the angle of the curtain panel 3 entering the guide rail 4 is constant and will not change, thereby ensuring that the winding and unwinding of the curtain panel 3 is smooth and will not jam.

[0021] In some embodiments, the auxiliary roller 5 is installed inside the roller shutter door cover 1, and its shape can be rhomboid or circular.

[0022] Preferably, the auxiliary roller 5 has a simple structure, is easy to install, and does not increase the overall installation difficulty of the roller shutter door.
