Description

Technical Field

[0001] This utility model relates to the field of curtain tracks, and in particular to a flexible curtain track. Background Technology

[0002] In daily life, when installing curtains, users need to pre-install curtain tracks on the ceiling. The rollers at the top of the curtain slide in the track, ensuring smooth curtain movement. Traditional curtain tracks are mostly long, straight rods. If there are corners in the installation location, users need to bend the curtain track to fit the corner. Currently, bending processes often involve directly using external force to bend the curtain track, which can easily damage it. Curtain tracks usually require multiple bends and adjustments to achieve a good fit with the wall, making existing curtain tracks quite inconvenient to bend. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figure 1 This utility model proposes a flexible curtain track, including several track frames 1 arranged at intervals. The track frames 1 are arranged in the shape of a spine, with gaps between adjacent track frames 1. The track frame 1 is provided with a sliding cavity 11. The bottom of the sliding cavity 11 is provided with a relief groove 12. The sliding cavity 11 is used for the sliding of the pulley at the top of the curtain fabric, and the relief groove 12 is used for the extension of the bottom end of the pulley to facilitate the connection between the pulley and the curtain fabric. The relief groove 12 is provided with snap-fit ​​grooves 13 on both sides.

[0028] A connector 2 is provided between adjacent track frames 1. One end of the connector 2 is fixedly connected to one track frame 1, and the other end is rotatably connected to another track frame 1. The connector 2 connects all the track frames 1 into a whole, allowing for a certain angle of deflection between adjacent track frames 1. In other designs, both ends of the connector 2 can be rotatably connected to the track frame 1. This design uses a fixed-end and rotatable-end connection to improve the overall strength of the track. Figure 1As shown, the track as a whole formed by connecting multiple connectors 2 with the track frame 1 can freely deflect within a certain angle. During installation, simply press the track against the wall, and the track frame 1 will automatically deflect to adapt to the curvature of the wall. The operation is simple and can also ensure the fit with the wall.

[0029] Meanwhile, the flexible pulley pad 3 in the sliding inner cavity 11 is connected in series with the track frame 1, such as... Figure 2 As shown, this embodiment uses two long flexible pulley pads 3, which are connected in series with all the track frames 1 to ensure that several track frames 1 maintain a relatively stable shape. When the track frame 1 deflects, the internal flexible pulley pads 3 can also bend accordingly. Of course, the flexible pulley pads 3 can also be set as multiple long strips. The upper surface of the flexible pulley pads 3 can provide a smooth rolling plane for the pulley. The bottom surface of the flexible pulley pads 3 is provided with a snap-fit ​​protrusion 31. The installation of the flexible pulley pads 3 is achieved by inserting the snap-fit ​​protrusion 31 into the snap-fit ​​groove 13.

[0030] See Figure 3 The connector 2 is fixed above the sliding inner cavity 11. One end of the connector 2 is provided with a connecting hole 21. The track frame 1 is provided with a rotating hole 14. A rotating shaft is provided in the connecting hole 21. The rotating shaft is rotatably connected in the rotating hole 14. The adjacent track frame 1 can be deflected with the rotating shaft as the axis.

[0031] See Figure 4 The other end of the connector 2 is provided with a plurality of positioning holes 22, preferably two or more. The track frame 1 is provided with a plurality of positioning connection holes 15. The positioning holes 22 are provided with positioning shafts that pass through the positioning connection holes 15. The arrangement of multiple positioning shafts can ensure the connection stability between the connector 2 and the track frame 1.

[0032] See Figure 4 The sliding inner cavity 11 is provided with a plurality of guide plates 16. The guide plates 16 can be set on the upper and lower surfaces of the sliding inner cavity 11. The guide plates 16 on both sides are respectively located on the outer side of the snap-fit ​​groove 13. The guide plates 16 can provide a guiding effect for the pulley during the curtain is pulled, so as to avoid the pulley from shifting position and causing the bottom end of the pulley to rub against the relief groove 12, which would affect the user's experience.

[0033] See Figure 4 A locking edge 17 is formed between the clearance groove 12 and the locking groove 13. A locking groove 32 is provided on the bottom surface of the flexible pulley pad. After the flexible pulley pad is installed in place, the locking edge 17 is embedded in the locking groove 32, which effectively prevents the flexible pulley pad from lifting up during use and affecting the smooth rolling of the pulley.

[0034] See Figure 3 or Figure 4 The sliding inner cavity 11 is provided with a relief cavity 18 above it. To save materials, the relief cavity 18 can be set as a positioning opening. The connector 2 is provided in the relief cavity 18. The two side walls of the relief cavity 18 are respectively provided with connecting grooves 181. The connecting grooves 181 are filled with reinforcing strips 182 that are connected in series with the track frame 1. The reinforcing strips 182 are preferably long strips. The reinforcing strips 182 are used to cooperate with the flexible pulley pads 3 to improve the stability of the overall shape of the track frame 1.

[0035] The bottom of the snap-fit ​​groove 13 is provided with a limiting groove 131, and the bottom of the snap-fit ​​protrusion 31 is provided with a limiting protrusion 311, such as Figure 3 , 4 The limiting slot 131 and the limiting boss 311 are both circular. During installation, the limiting boss 311 and the limiting slot 131 are aligned first, and then the flexible pulley pad is inserted into the snap-fit ​​groove 13 from the side of the track frame 1. The cooperation of the limiting slot 131 and the limiting boss 311 ensures that the flexible pulley pad 3 will not enter the sliding inner cavity 11, thus ensuring smooth rolling of the pulley.

[0036] This curtain track can be used with regular long straight tracks, such as... Figure 5 A connecting frame 19 is fitted on the track skeleton 1 at both ends. The connecting frame 19 and the track skeleton 1 can be fixedly connected by screws or other means. The long straight guide rail 4 can be inserted into the free end face outside the connecting frame 19. The sliding cavities 11 inside the two tracks are interconnected, and the pulley can slide smoothly in the combined track.

[0037] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the scope of the present utility model are protected by the present utility model.
