[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] like Figure 1-7 The example shown is an embodiment provided by the utility model.

[0036] The embodiment of the utility model provides a curtain track device, including: a guide rail 10, a plurality of hanging parts 20 and a plurality of coil springs 30. The hanging parts 20, as the name implies, are used to hang objects. Specifically, in this embodiment, the hanging parts 20 are used to hang curtains, similar to curtain hooks. The hanging parts 20 are slidably arranged in the guide rail 10 along the length direction of the guide rail 10. After a curtain is hung under the hanging parts 20, the curtain can be driven to unfold or retract along the guide rail 10. A plurality of coil springs 30 are arranged on the hanging member 20 in a one-to-one correspondence. Specifically, the hanging member 20 is provided with a receiving chamber 21, a connecting port 23 and an escape port 22. The coil spring 30 is arranged horizontally in the receiving chamber 21. The telescopic end of the coil spring 30 extends from the escape port 22 in the horizontal direction and is connected to the connecting port 23 of another hanging member 20 adjacent thereto. All the hanging members 20 are connected in series through the coil spring 30. As long as the hanging member 20 at the outer end is pulled, all the coil springs 30 can be stretched by the tension at the same time, and drive the remaining hanging members 20 to move in the guide rail 10. When the outermost hanging member 20 is pulled, When the parts 20 are no longer under tension or are not fixed, under the action of the elastic force of the coil spring 30, all the hanging parts 20 will move closer to each other. In the specific implementation, the first hanging part 20 at the end is usually fixed to one end of the guide rail 10, so that the remaining hanging parts 20 will move closer to the first hanging part 20 when they are folded. In the fully folded state, all adjacent hanging parts 20 are close to each other, and all the coil springs 30, except for the part extending out of the avoidance port 22 and connected to the other connection port 23, are just received in the storage groove. Different coil springs 30 will not stack on each other or affect each other and cause jamming during the winding process. In addition, the coil spring 30 is made of metal, which is more durable than traditional plastic connectors.

[0037] Specifically, the avoidance opening 22 and the connection opening 23 are both located at the upper part of the accommodating chamber 21, so that all the coil springs 30 can be extended and retracted in the same direction, and it is also convenient to connect with another adjacent hanging member 20. The avoidance opening 22 is strip-shaped, with the same cross-sectional shape as the coil spring 30, and the height of the avoidance opening 22 is adapted to the thickness of the coil spring 30, so that the outer end of the coil spring 30 can just extend from the avoidance opening 22. Figure 7As shown, in another embodiment, a tension spring A can be selected to replace the coil spring 30. One end of the tension spring A is fixed in the accommodating chamber 21, and the other end extends from the avoidance opening 22 to be connected to the connecting opening 23 on the adjacent hanging member 20. Of course, the size and shape of the avoidance opening 22 should be adaptively adapted to the end of the tension spring A, and the position of the avoidance opening 22 should also be changed from the top of the accommodating chamber 21 to the side wall.

[0038] Furthermore, the coil spring 30 includes an integrally arranged limiting portion 31, a telescopic portion 32 and a connecting portion 33, wherein the limiting portion 31 is located at the inner end of the telescopic portion 32, and the connecting portion 33 is located at the outer end of the telescopic portion 32. The width L1 of the connecting portion 33 and the width L2 of the telescopic portion 32 are less than or equal to the width L3 of the avoidance opening 22, so that the connecting portion 33 at the outer end of the coil spring 30 and the telescopic portion 32 of the main body can both extend normally from the avoidance opening 22, and the width L3 of the avoidance opening 22 is less than the width L4 of the limiting portion 31, so as to prevent the coil spring 30 from falling out of the accommodating chamber 21 as a whole after the telescopic portion 32 is fully extended, thereby playing a limiting role. Specifically, the connecting portion 33 of a coil spring 30 can be snapped into the connecting port 23 on the hanging component 20 adjacent to the hanging component 20 on which it is located. The connecting portion 33 is connected to the front end of the telescopic portion 32 in a "T" shape, and the shape of the connecting port 23 is also a corresponding "T" shape. The connecting portion 33 is snapped into the connecting port 23 to connect two adjacent hanging components 20. Similarly, all hanging components 20 are connected one by one by different coil springs 30 to achieve a similar series effect.

[0039] Furthermore, the width of the outer end of the telescopic portion 32 is smaller than the width of the inner end thereof, and the width of the telescopic portion 32 gradually increases from the outer end to the inner end. The stretching length of the telescopic portion 32 is proportional to the required pulling force, so that in the process of pulling the telescopic portion 32 outward, the further back it is pulled, the greater the force required. Driven by the stretching of the coil spring 30, the spacing between any two adjacent hanging parts 20 tends to be equal, thereby being able to drive the curtain to present a nearly uniform expansion effect.

[0040] Furthermore, rollers 24 are provided on both sides of the hanging member 20, and slide grooves 11 are provided on the inner walls of both sides of the guide rail 10. The rollers 24 are rollingly connected to the slide grooves 11. The rollers 24 can reduce the friction between the hanging member 20 and the inner wall of the guide rail 10 during the sliding process of the hanging member 20, so that the hanging member 20 slides more smoothly, thereby making the opening and closing of the curtains smoother.

[0041] Specifically, an opening 13 is provided at the bottom of the guide rail 10 along its length direction, and a hanging rod 25 is rotatably provided at the bottom of the hanging member 20. The hanging rod 25 vertically passes through the opening 13 downward, and a curtain clip 26 is provided at the lower end of the hanging rod 25 for clamping the upper edge of the curtain.

[0042] Furthermore, a transverse axis 12 is provided in the guide rail 10 along its length direction, and the hanging member 20 is slidably connected to the transverse axis 12. Among them, a worm wheel 211 and a worm 212 are provided in the accommodating chamber 21, and the worm 212 is sleeved on the transverse axis 12, and the worm 212 is meshed with the worm wheel 211, and the worm wheel 211 is sleeved on the upper end of the hanging rod 25, and the transverse axis 12 can drive the worm 212 to rotate in the horizontal direction, and then the worm wheel 211 drives the hanging rod 25 to rotate in the vertical direction. Generally speaking, the dream curtain is composed of individual curtain pieces, and different curtain pieces rotate in coordination with the rotation of their respective hanging rods 25, so as to achieve different shading or light transmission effects. Among them, the rotation of the transverse axis 12 can be automatically controlled by setting a motor connection.
