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.

[0032] 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.

[0033] 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.

[0034] like Figure 1-5 The example shown is an embodiment provided by the utility model.

[0035] The embodiment of the utility model provides a curtain sliding 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 guide rail 10 is set according to the contour of the upper edge of the window, generally a straight rail of a straight line or a semi-frame type curved rail. The semi-frame type curved rail is mostly used for bay windows in balconies or rooms. One of the hanging parts 20 can be fixedly set at one end of the guide rail 10, that is, the starting end, and the remaining hanging parts 20 are slidably set in the guide rail 10 along the length direction. A number of coil springs 30 are set on the hanging parts 20 one by one. The coil spring 30 is longitudinally installed on the hanging parts 20 so that the axis of the coil spring 30 is perpendicular to the horizontal plane where the guide rail 10 is located. The coil spring 30 can be extended and retracted along the length direction of the guide rail 10. The telescopic end of the coil spring 30 extends from the hanging part 20 along the length direction of the guide rail 10 and is connected to another adjacent hanging part 20. The distance between two adjacent hanging parts 20 is equal to the telescopic length of the coil spring 30. All the coil springs 30 and the hanging parts 20 form an integrated telescopic elastic component. The sliding of the hanging part 20 can drive the coil spring 30 to be extended and retracted. Similarly, the extension and retraction of the coil spring 30 can also drive the hanging part 20 to slide. In the actual implementation process, the upper edge of the curtain is first hung on each hanging member 20 at equal distances, and the hanging member 20 farthest from the starting end is pulled to extend the coil spring 30 and drive the other hanging members 20 to slide, thereby driving the curtain located below the hanging member 20 to unfold. The guide rail 10 is a straight rail or a curved rail. When the guide rail 10 is a curved rail, the bending direction of the coil spring 30 is consistent with the bending direction of the guide rail 10. Due to the bending characteristics of the coil spring 30, when the guide rail 10 turns, the bending direction of the coil spring 30 is set to be consistent with the bending direction of the guide rail 10, which can reduce the contact between the coil spring 30 and the inner wall of the guide rail 10 during the extension driven by the hanging member 20. At the same time, the surface of the coil spring 30 is smoother than that of the spring. Even if it contacts the inner wall of the guide rail 10, it will not generate too much friction and friction noise, which can reduce the wear of the inner wall of the guide rail 10 and reduce the adverse effects on use.

[0036] Furthermore, the coil spring 30 includes an integrally arranged limiting portion 31, a telescopic portion 32 and a connecting portion 33, the limiting portion 31 is located at the inner end of the telescopic portion 32, the connecting portion 33 is located at the outer end of the telescopic portion 32, that is, the telescopic end of the coil spring 30, the width L1 of the connecting portion 33 is greater than the width L2 of the outer end of the telescopic portion 32, the width L4 of the limiting portion 31 is greater than the width L1 of the connecting portion 33 and the width L3 of the inner end of the telescopic portion 32, the telescopic portion 32 increases in width 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, and 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 an effect of nearly uniform expansion.

[0037] Specifically, the hanging member 20 includes a receiving portion 21, a sliding portion 22 and a hanging portion 23 arranged in sequence from top to bottom. The receiving portion 21 is in the shape of a groove with an opening upward. The coil spring 30 is longitudinally arranged in the receiving portion 21. The sliding portion 22 is slidably connected to the guide rail 10. The hanging portion 23 is used to hang the curtain. The hanging portion 23 can be ring-shaped or hook-shaped. A strip-shaped avoidance hole 211 is arranged on the receiving portion 21. The avoidance hole 211 is arranged longitudinally. Both the connecting portion 33 and the telescopic portion 32 can pass through the avoidance hole 211. The width L4 of the limiting portion 31 is greater than the height H of the avoidance hole 211, so that the coil spring 30 will not be separated from the receiving portion 21 after the telescopic portion 32 is stretched to the longest state, which plays a limiting role.

[0038] Furthermore, a connecting groove 212 is provided outside the accommodating portion 21, and the connecting portion 33 can be engaged with the connecting groove 212. Specifically, the connecting portion 33 of a coil spring 30 can be engaged with the connecting groove 212 on the adjacent hanging portion 23 of the hanging member 20 where 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 groove 212 is also a corresponding "T" shape. The connecting portion 33 is engaged in the connecting groove 212 to connect two adjacent hanging members 20. By analogy, all hanging members 20 are connected one by one by different coil springs 30 to achieve a similar series effect. In addition, the avoidance hole 211 and the connecting groove 212 are located on the same side of the accommodating portion 21, so that all coil springs 30 can be stretched in the same direction.

[0039] Furthermore, a rack 11 is provided at the top of the guide rail 10 along the length direction, and the length and shape of the rack 11 are adapted to the guide rail 10. A locking mechanism 12 is slidably provided in the guide rail 10, and the locking mechanism 12 is connected to the outermost hanging member 20, which refers to the hanging member 20 farthest from the first fixed member 20 at the starting end of the guide rail 10. The locking mechanism 12 is movably engaged with the rack 11, and the function of the locking mechanism 12 is to fix the outermost hanging member 20 at an unspecified position in the guide rail 10, so that all the coil springs 30 cannot rebound after being pulled open, thereby keeping the curtain in the opening position required by the user. Specifically, the locking mechanism 12 includes a latching tooth 121, a reset spring 122, and a traction portion 123 arranged in sequence from top to bottom, the latching tooth 121 can be engaged with the rack 11, the traction portion 123 is used to pull the latching tooth 121 downward, and the reset spring 122 is used to lift the latching tooth 121 upward. In actual use, by applying a force downward that is sufficient to overcome the elastic force of the return spring 122 to pull the traction part 123, the latch tooth 121 can be separated from the rack 11, so that the coil spring 30 recovers and rebounds; conversely, if the traction part 123 is not pulled downward or the downward pulling force is not sufficient to overcome the elastic force of the return spring 122, the latch tooth 121 remains engaged with the rack 11.
