Description

Technical Field

[0001] The utility model relates to the technical field of curtain accessories, in particular to a silent curtain guide rail. Background Art

[0002] Most of the existing curtain rails are formed by extrusion of aluminum profiles. By installing a buffer strip in the curtain rail, the wheel body of the pulley moves on the surface of the buffer strip when sliding, thereby reducing the noise during sliding.

[0003] For example, the silent composite electric curtain rail disclosed in Chinese patent document CN215424044U comprises a support plate, side panels are provided on both sides of the bottom of the support plate, and the side panels are L-shaped; baffles are provided at the bottom of the inner cavities of the side panels, and mounting grooves are provided on the opposite sides of the baffles, and buffer strips are embedded in the mounting grooves; a limit block is provided at the bottom of the support plate, and the baffle and the limit block form a slide rail compartment at the bottom of the support plate.

[0004] In the above disclosed prior art, since the buffer strip is arranged in the installation groove on the side facing the baffles on both sides, and since the buffer strip does not completely wrap the baffles on both sides, during actual use, the pulley can still contact the surface of the baffles on both sides. When the curtains are pulled, multiple pulleys rub against the baffles at the same time. Although there is less noise at the contact between the wheel body of the pulley and the buffer strip, there are abnormal noises at the baffles in turn, resulting in relatively large noise.

Multiple sections of the inner guide rails 1 can be disassembled during transportation, which is convenient for transportation. The plastic strip body 11 is wrapped on the support plate 6 to facilitate the sliding of the curtain pulley on the plastic strip body 11. At the same time, since the lower stopper 16 is also arranged on the plastic strip body 11, the excessive contact between the curtain pulley and the inner guide rail 1 when sliding is reduced, thereby preventing noise.

[0018] The silent strip 3 of this embodiment can be inserted through and connected to the multi-section inner guide rail 1, so that the connection of the multi-section inner guide rail 1 is more stable, and the multi-section inner guide rail 1 is prevented from shaking in the connecting rail 2. Moreover, when the curtain pulley slides on the silent strip 3, when it slides to the gap between the multi-section inner guide rails 1, the silent strip 3 can be used to fill the gap, thereby preventing noise from occurring when the curtain pulley passes between the gaps.

[0019] The upper end surface of the support plate 6 of the present embodiment is provided with a raised embedding block 9, a limiting groove 8 is provided at the connection between the side plate 4 and the support plate 6, and a beveled end head 7 is provided at the end of the support plate 6 away from the limiting groove 8, and an embedding groove 15 corresponding to the embedding block 9 is provided at the lower end of the plastic strip body 11, and a limiting head 12 is provided at one end of the plastic strip body 11 close to the limiting groove 8, and a wrapping end 13 is provided at the lower side of the other end, and an end head slot 14 is provided on the side of the wrapping end 13 close to the beveled end head 7; by inserting the limiting head 12 into the limiting groove 8 and then pressing down the plastic strip body 11, so that the embedding block 9 is inserted into the embedding groove 15, and at the same time, the end head slot 14 wraps the beveled end head 7, the whole plastic strip body 11 can be pushed into the inner guide rail 1, and the whole plastic strip body 11 is more stable to prevent it from detaching from the inner guide rail 1.

[0020] It is worth noting that the plastic strip body 11, the wrapping end 13 and the lower stopper 16 of the present embodiment are an integrated structure and are all made of plastic material. Since the inner guide rail 1 is usually made of aluminum alloy, there is no need to form a metal lower stopper on the support plate 6 of the inner guide rail 1, which can reduce product costs, and the lower stopper 16 made of plastic material is more effective in preventing noise when contacting the curtain pulley.

[0021] The lower end surface of the support plate 6 of the present embodiment is provided with a docking slot 10, and a guide rail cavity for clamping the guide rail body is provided in the docking rail 2, and guide rail support strips 17 are provided on both sides of the lower end of the guide rail cavity, and the ends of the guide rail support strips 17 are provided with hooks 18 corresponding to the docking slot 10; by clamping the inner guide rail 1 in the guide rail cavity and supporting it through the guide rail support strips 17, the multi-section inner guide rail 1 is made flatter in the guide rail cavity, and when the hooks 18 are hooked in the docking slot 10, the multi-section inner guide rail 1 is more stable.

[0022] It is worth noting that the upper ends of the side panels 4 on both sides of this embodiment are connected by a connecting plate, and the two ends of the connecting plate are clamped in the guide rail cavity, so that the upper end of the inner guide rail 1 can be stabilized in the guide rail cavity through the connecting plate to prevent the entire inner guide rail 1 from shaking.
