When in use, the upper end of the curtain is evenly hung on a plurality of hanging parts 8, and one upper corner thereof is fixed to the front end of the track 1, and the other upper corner is hung on the hanging part 8 far from the roller head 2. The user can drive the output end of the roller head 2 to rotate, so as to drive the hanging part 8 far from the roller head 2 to slide through the transmission component 33, driving the curtain hung on the hanging part 8 to slide and unfold or gather. When the user releases the driving force on the output end of the roller head 2, the output end of the roller head 2 will stop rotating and self-lock, thereby restricting the movement of the transmission component 33, making the hanging part 8 far from the roller head 2 positioned and hovering, preventing the curtain from being easily offset by external forces, so that the user can fix the opening and closing range of the curtain and improve the use experience. The roller head 2 can be obtained through the market channel and will not be elaborated in this embodiment.

[0026] In one embodiment, the transmission component 33 can be a rack. The rack is slidably connected to the track 1 in the same direction. The hanging part 8 far from the roller head 2 is fixedly connected to the rack. The output end of the roller head 2 is in transmission connection with the rack through a gear (not shown in the attached drawing), so that when the output end of the roller head 2 rotates, it can drive the rack to slide, thereby driving the hanging part 8 far from the roller head 2 to slide, making the curtain hung on the hanging part 8 unfold or gather.

One end of the gear belt 6 is sleeved on the driving gear 4, and the other end of the gear belt 6 is sleeved on the driven gear 5. Both the driving gear 4 and the driven gear 5 are engaged with the gear belt 6. The hanging part 8 far from the roller head 2 is connected to a part of the gear belt 6.

[0028] In one embodiment, a lead screw can be coaxially connected to the output end of the roller head 2. The lead screw is engaged with one side of the driving gear 4. The output end of the roller head 2 can be in transmission connection with the driving gear 4 through the lead screw (not shown in the attached drawing).

[0029] Further, the output end of the roller head 2 is in transmission connection with the driving gear 4 through a bevel gear 21. When the output end of the roller head 2 rotates, it will drive the driving gear 4 to rotate through the bevel gear 21. Using the driving gear 4 to drive the gear belt 6 to roll. At this time, the driven gear 5 will rotate adaptively, thereby driving the hanging part 8 far from the roller head 2 to slide along the track 1.

[0030] Further, the transmission assembly 3 further includes a slider 7 which is slidably connected to the slide rail 1. A plurality of hanging members 8 are located between the slider 7 and the rolling curtain head 2, and the hanging member 8 far from the rolling curtain head 2 is connected to the slider 7. The gear belt 6 is formed into a loop by connecting its two ends. The side wall of the slider 7 is fixedly connected to the connection part of the gear belt 6. The two ends of the gear belt 6 can be fixedly connected to the slider 7 by means of bonding or screwing, so as to assemble the cut-to-size gear belt 6 on the slide rail 1 for use, and fix the two ends of the gear belt 6 through the slider 7.

[0031] Further, a front end belt buckle 71 and a rear end belt buckle 72 are sequentially and fixedly arranged on the side wall of the slider 7 along the length direction of the slide rail 1. The front end belt buckle 71 is buckled on the front end of the gear belt 6, and the rear end belt buckle 72 is buckled on the rear end of the gear belt 6, so as to fix the front end and the rear end of the gear belt 6 on the slider 7 through the belt buckles, realize the connection of the two ends of the gear belt 6, and at the same time facilitate the gear belt 6 to drive the slider 7 to slide, and use the slider 7 to pull the hanging member 8 far from the rolling curtain head 2 to slide along the slide rail 1.

[0032] Further, an extension arm 73 extending towards the rear end of the slide rail 1 is provided on the slider 7, and the extending end of the extension arm 73 is used for hanging the upper corner of the curtain.

[0033] Further, a hanging port 11 is provided on one side of the front end of the slide rail 1, and the hanging port 11 is used for hanging the upper corner of the curtain.

[0034] In this embodiment, one upper corner of the curtain can be hung on the extending end of the extension arm 73, and the other upper corner of the curtain can be hung on the hanging port 11, so that the curtain can be unfolded to be flush with the two ends of the slide rail 1, avoiding gaps due to incomplete shading of the curtain during actual use, and ensuring the shading effect.

[0035] Further, the curtain slide rail 1 device further includes a plurality of elastic members 9. A plurality of hanging members 8 are sequentially connected through the elastic members 9, and the hanging member 8 close to the rolling curtain head 2 is connected to the front end of the slide rail 1 through the elastic member 9.

[0036] Further, the elastic member 9 is a spring. When the hanging member 8 far from the rolling curtain head 2 slides towards the rear end of the slide rail 1 under the drive of the transmission assembly 33, a plurality of hanging members 8 will be linked through the spring. At this time, the forces on the plurality of springs are the same, so the stretching lengths are the same, so that the plurality of hanging members 8 slide synchronously and equidistantly, so that the curtain unfolds evenly everywhere, avoiding the situation of local overlap of the curtain, improving the visual effect, and the same is true when the curtain gathers.

[0037] Further, the other end of the rolling curtain head 2 is provided with a driving end, the driving end can drive the output end to rotate, a pull bead 22 is sleeved on the driving end, the lower end of the pull bead 22 extends downward to the lower part of the slide rail 1, and the user can pull the pull bead 22 to make it roll, thereby driving the rotation of the driving end of the rolling curtain head 2 and driving the rotation of its output end. This is the prior art and will not be elaborated in this embodiment.
