Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain track technology, and in particular to a lightweight and easy-to-slide curtain track. Background Technology
[0002] Curtain tracks are curtain accessories used to hang curtains, facilitating their opening and closing, and enhancing the aesthetics of the curtain fabric. There are many types of curtain tracks, divided into two main categories: visible tracks and concealed tracks. Visible tracks include wooden rods, aluminum alloy rods, steel pipe rods, wrought iron rods, and PVC rods, among others. Concealed tracks include nano tracks, aluminum alloy tracks, and silent tracks, made from materials such as PVC, iron, copper, wood, and aluminum alloy.
[0003] As the length of window openings in residential and commercial spaces increases, a single curtain track often cannot meet the span requirements. Therefore, it is necessary to connect the ends of two or more tracks on-site to form a continuous track.
[0004] However, due to factors such as manufacturing tolerances, transportation deformation, installation level, and thermal expansion and contraction, adjacent tracks are prone to misalignment, warping, or height differences at the splicing point. When the pulley passes through the splicing position, it may experience jerking, shaking, or even jamming due to the step or gap, resulting in increased running resistance and noise. Long-term operation will also exacerbate the wear of the pulley and track, shortening its service life. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lightweight and easy-to-slide curtain track to solve the problems of jerky operation, increased noise and accelerated wear caused by misalignment, warping or height difference at the joint of adjacent tracks.
[0006] This utility model provides a lightweight and gliding curtain track, including a track body and a pulley assembly placed inside the track body. The track body is provided with a pair of track bodies arranged side by side. Positioning holes are equidistantly opened on the upper surface of the track body. A connecting assembly is provided between the two track bodies. The connecting assembly is used to fix the two track bodies together. A first slide rail is symmetrically fixedly connected to the lower end of the inner wall of the track body at both the front and back.
[0007] Preferably, the connecting component includes a connecting frame and a second slide rail. The connecting frame is fitted inside the two track bodies. A segmented strip is fixedly connected to the outer wall of the connecting frame. The left and right sides of the segmented strip abut against the track bodies. A pair of second slide rails are provided and fixedly connected to the front and rear sides inside the connecting frame.
[0008] Preferably, the pulley assembly includes a fixed frame and a connecting rod. The fixed frame is triangular and placed inside the track body. Its lower end has two symmetrical rotating shafts on both sides. Each rotating shaft is rotatably connected to a first roller, which rolls and cooperates with a first slide rail. The upper end of the fixed frame has a second roller that rotates through a rotating shaft. The second roller cooperates with a second slide rail. The connecting rod is fixedly connected to the lower end of the fixed frame, and a suspension ring is fixedly connected to the lower side wall of the connecting rod.
[0009] Preferably, the upper end of the first slide rail is provided with a first pulley groove, the first roller is located inside the first pulley groove and abuts against it, and the upper end of the second slide rail is provided with a second pulley groove, the second roller and the second pulley groove cooperate with each other.
[0010] Preferably, the second pulley groove has an inclined angle at both the left and right ends.
[0011] Preferably, the track body is made of aluminum alloy.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model forms a gradual entry by setting an inclined angle at both ends of the second pulley groove, which allows the second roller to transition smoothly, significantly reducing the impact and wear when entering the connecting component, while automatically correcting the height difference and improving the smoothness of sliding.
[0013] 2. This utility model ensures that the pulley assembly always runs along a predetermined trajectory by having a first roller roll inside the first pulley groove and a second roller roll inside the second pulley groove, effectively avoiding lateral misalignment and vibration, and improving system stability and service life.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] like Figure 1-4 As shown, this utility model has the following two specific embodiments.
[0018] Example 1 A surveying support device includes a track body 1 and a pulley assembly 3 placed inside the track body 1. The track body 1 is provided with a pair of track bodies arranged in a left-right distribution. Positioning holes 13 are provided at equal intervals on the upper surface of the track body 1. A connecting assembly 2 is provided between the two track bodies 1. The connecting assembly 2 is used to fix the two track bodies 1 together. A first slide rail 11 is symmetrically fixedly connected to the lower end of the inner wall of the track body 1 at the front and back. The connecting component 2 includes a connecting frame 21 and a second slide rail 22. The connecting frame 21 is fitted inside the two track bodies 1. A segmented strip 24 is fixedly connected to the outer wall of the connecting frame 21. The left and right sides of the segmented strip 24 abut against the track body 1. A pair of second slide rails 22 are provided and fixedly connected to the front and rear sides inside the connecting frame 21. The pulley assembly 3 includes a fixed frame 31 and a connecting rod 34. The fixed frame 31 is triangular and placed inside the track body 1. The lower end of the fixed frame 31 has symmetrical rotating shafts on both sides. Each rotating shaft is rotatably connected to a first roller 32, which rolls and engages with the first slide rail 11. The upper end of the fixed frame 31 has a second roller 33 that rotates through a rotating shaft. The second roller 33 engages with the second slide rail 22. The connecting rod 34 is fixedly connected to the lower end of the fixed frame 31, and a suspension ring 35 is fixedly connected to the lower side wall of the connecting rod 34.
[0019] In this embodiment, as Figures 1-3 As shown, the connecting frame 21 is embedded in the joint end of the two track bodies 1, and its segmented strips 24 are tightly fitted with the track end face to form a rigid bridge; then the track body 1 is fixed to the wall by expansion bolts through the positioning holes 13, and then the pulley assembly 3 is installed into the track body 1, so that the four first rollers 32 at the lower end of the triangular fixing bracket 31 always roll on the first slide rail 11; when the curtain is pulled, the connecting rod 34 moves the fixing bracket 31 to the position of the connecting frame 21, and the upper second roller 33 falls on the second slide rail 22, so that the first roller 32 can smoothly pass over the track joint and achieve a smooth transition.
[0020] Example 2 The difference from Embodiment 1 is that this embodiment discloses a first pulley groove 12 and a second pulley groove 23 for limiting the first roller 32 and the second roller 33; The upper end of the first slide rail 11 is provided with a first pulley groove 12, the first roller 32 is located inside the first pulley groove 12 and abuts against it, the upper end of the second slide rail 22 is provided with a second pulley groove 23, and the second roller 33 cooperates with the second pulley groove 23. The second pulley groove 23 has inclined angles at both ends; The track body 1 is made of aluminum alloy.
[0021] In this embodiment, as Figure 2 and Figure 4 As shown, the track body 1 is integrally extruded from aluminum alloy, with the front and rear walls each extending inward horizontally to form a first slide rail 11. The upper end of the first slide rail 11 is milled with a first pulley groove 12 in the shape of a U. The first roller 32 travels inside the first pulley groove 12, which not only limits radial runout but also prevents axial displacement. The second slide rail 22 in the connecting frame 21 is also milled with a second pulley groove 23. The groove end expands outward at a 5° inclination angle to form a trumpet-shaped guide section. The second roller 33 is first raised and then lowered under the guidance of the inclination angle to achieve a shock-free transition. The aluminum alloy material reduces the overall weight while maintaining high rigidity, ensuring that each slide groove does not deform over a long period of time, and that the pulley operation always maintains low noise, low resistance, and no shaking.
[0022] The working principle of this utility model is as follows: During installation, the ends of the two track bodies 1 are joined together, and the connecting frame 21 is inserted into the cavity between the two track bodies 1. The segment strip 24 fits tightly with the end face of the track to form a rigid bridge. Then, after the pulley assembly 3 is installed, the four first rollers 32 fall into the first pulley groove 12 in pairs, and the second rollers 33 are suspended inside the track body 1. When an external force pulls the curtain, the connecting rod 34 drives the triangular fixing frame 31 to move along the track; the first roller 32 rolls along the first pulley groove 12, providing the main load and guidance; when the fixing frame 31 reaches the area of the connecting frame 21, the inclination angles at both ends of the second pulley groove 23 first contact the second roller 33, causing it to gradually rise and smoothly enter the second pulley groove 23; during this process, the first roller 32 and the second roller 33 form a double-track support, the first roller 32 briefly leaves the first pulley groove 12 and crosses the seam, while the second roller 33 undertakes the transition guidance, eliminating the step difference; after the second roller 33 passes, the first roller 32 falls back into the first pulley groove 12 of the next round and continues to run smoothly. The aluminum alloy track and chute maintain high rigidity and are lightweight, and the whole system achieves low friction, low noise, and continuous sliding without jerking.
[0023] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
