Description

Technical Field

[0001] This utility model belongs to the technical field of curtain equipment, specifically relating to a hanging wheel structure set on a decorative cover plate. Background Technology

[0002] Electric curtains mainly consist of a track, a transmission assembly, and curtain fabric. The transmission assembly has pulleys at both ends of the track. A synchronous belt inside the track is wound around the pulleys and circulates within the track. A trolley and a hanging wheel slide within the track. The curtain fabric is hung on the hanging wheel, and the trolley is connected to the synchronous belt. In use, the pulleys rotate, driving the synchronous belt, which in turn drives one end of the curtain fabric to slide along the track via the trolley, thus opening and closing the curtain. However, in existing electric curtains, when the curtain fabric is pulled towards the center, the end of the fabric is tightened, which can easily lead to light leakage at the end. This also causes uneven wrinkles in different parts of the curtain, resulting in a less harmonious appearance and inconsistent light transmission. Therefore, improvements are necessary. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a hanging wheel structure installed on a decorative cover plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hanging wheel structure set on a decorative cover plate, comprising a decorative cover plate set on one side of a transmission box, a curtain track at one end of the transmission box, and a track groove axially provided on one side of the curtain track, within which a plurality of track hanging wheels connected to the curtain fabric are slidably arranged; a cover plate movable groove coaxially arranged along the track groove on the decorative cover plate, within which at least one movable hanging wheel connected to the curtain fabric is slidably arranged; and a fixed hanging wheel located outside one end of the cover plate movable groove and connected to the curtain fabric is provided at the end of the decorative cover plate away from the curtain track.

[0005] In the aforementioned hanging wheel structure set on the decorative cover plate, one end of the decorative cover plate extends to the outer side of one end of the curtain track, and the decorative cover plate covers one end of the track groove.

[0006] In the aforementioned hanging wheel structure installed on a decorative cover plate, the cover plate movable groove is located below the track groove, and the cover plate movable groove and the track groove are arranged parallel to each other.

[0007] In the aforementioned hanging wheel structure on a decorative cover plate, the decorative cover plate has a recessed portion in the middle of the side near the transmission box, which is recessed toward the side of the decorative cover plate away from the transmission box. The recessed portion forms a boss in the middle of the side of the decorative cover plate away from the transmission box. The boss extends axially from one end of the decorative cover plate to the other end. The cover plate movable groove is axially formed on the boss and is connected to the recessed portion.

[0008] In the above-mentioned hanging wheel structure set on the decorative cover plate, the two sides of the recessed portion are respectively connected to the side of the decorative cover plate near the transmission box through the first arc-shaped transition portion, and the two sides of the boss are respectively connected to the side of the decorative cover plate away from the transmission box through the second arc-shaped transition portion.

[0009] In the aforementioned hanging wheel structure installed on a decorative cover plate, the movable hanging wheel and the fixed hanging wheel each include a vertically arranged hanging wheel rod, and the upper end of the hanging wheel rod is provided with a hanging wheel seat, the diameter of which is larger than the diameter of the hanging wheel rod.

[0010] In the aforementioned hanging wheel structure installed on a decorative cover plate, the hanging wheel rod of the movable hanging wheel slides through the movable groove of the cover plate, and the hanging wheel seat of the movable hanging wheel is located in the recessed portion. The recessed portion has guide grooves on both sides located on the first arc-shaped transition portion and extending from one end of the movable groove of the cover plate to the other end. The lower end of the hanging wheel seat has guide portions on both sides that slide in cooperation with the guide grooves.

[0011] In the aforementioned hanging wheel structure installed on a decorative cover plate, the fixed hanging wheel is installed at the end of the cover plate's movable groove away from the curtain track via a limiting and fixing structure.

[0012] In the aforementioned hanging wheel structure installed on a decorative cover plate, the limiting and fixing structure includes a fixing groove located at the end of the cover plate movable groove away from the curtain track and connected to the cover plate movable groove. The hanging wheel rod of the fixed hanging wheel is inserted into the fixing groove. A fixing frame located inside the fixing groove is provided in the recessed part, and the fixing frame has a partition plate extending to the space between the fixing groove and the cover plate movable groove. The hanging wheel seat of the fixed hanging wheel is located in the fixing frame.

[0013] In the aforementioned hanging wheel structure installed on the decorative cover plate, the movable hanging wheel and the fixed hanging wheel are the same size, and the hanging wheel rods of the movable hanging wheel and the fixed hanging wheel are respectively provided with mounting holes.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. A decorative cover is installed at one end of the curtain track on the outside of the transmission box to serve a decorative purpose and enhance the overall aesthetics of the curtains;

[0016] 2. Fixed rollers can hold the ends of the curtain fabric in place, preventing light leakage when the curtain is pulled towards the center. At the same time, movable rollers can move with the curtain fabric, acting as a buffer and preventing the ends of the curtain fabric from being pulled too tight. This ensures that the folds of the curtain fabric are consistent and well-coordinated. Attached Figure Description
