[0036] The plug-in assembly 2 includes a plug-in base 21 and a plug-in transmission gear 22, and the plug-in transmission gear 22 is arranged in the plug-in base 21;

[0037] The curtain rod 1 is provided with end transmission gears 3 at both ends, and the two end transmission gears 3 are connected by a transmission belt, and the pulley 4 is connected to the transmission belt;

[0038] One end of the curtain rod 1 is inserted into the plug-in base 21 so that one end transmission gear 3 of the curtain rod 1 is meshed with the plug-in transmission gear 22 .

[0039] In the curtain rail that is easy to transport, when transportation is required, the two curtain rods 1 can be separated from the plug-in assembly 2 respectively, thereby effectively shortening the length of the telescopic rail during transportation, which is more convenient for transportation. Figure 1-4As shown, during use and installation, after the two curtain rods 1 are plugged into the plug-in assembly 2, only one of the end transmission gears 3 needs to be rotated, and the corresponding transmission belt can be driven to move by cooperating with the other end transmission gear 3 of the same curtain rod 1, thereby driving the pulley 4 corresponding to the curtain rod 1 to move, and the pulley 4 can drive the curtain hung thereon to move. At the same time, through the plug-in transmission gear 22, the end transmission gear 3 of the other curtain rod 1 can be driven to rotate, and the two end transmission gears 3 of the other curtain rod 1 cooperate to drive the corresponding transmission belt to move, thereby driving the pulley 4 corresponding to the curtain rod 1 to move, and the pulley 4 can drive the curtain hung thereon to move, so that the opening and closing of the curtains can be achieved.

[0040] It is worth noting that if Figure 5-7 As shown, it also includes a transmission box 5 and a pulley hook 6. The curtain rod 1 is provided with a track 11, and the transmission box 5 is arranged on one of the curtain rods 1; the transmission box 5 includes a driving gear 51, and the transmission box 5 is arranged on the side wall of one of the curtain rods 1 and penetrates into the curtain rod 1 from the side wall of the curtain rod 1, so that the driving gear 51 is arranged outside the curtain rod 1, and the driving gear 51 is connected to the end transmission gear 3 away from the plug-in base 21; the transmission box 5 drives the end of one of the curtain rods 1 When the transmission gear 3 rotates, the end transmission gear 3 in the other curtain rod 1 can be driven through the transmission belt and the plug-in transmission gear 22 in the plug-in base 21. Therefore, only one driving source is needed to drive the pulley of the entire telescopic slide rail; the transmission box 5 is set on the curtain rod 1 and penetrated into the curtain rod 1 from the side wall of the curtain rod 1, so that the pulley 4 will not be blocked from pushing the pulley hook 6 to slide on the track 11 on the curtain rod 1, so that the pulley hook 6 can slide to the end of the track 11 of the curtain rod 1, avoiding the situation that the curtain does not cover the window tightly;

[0041] The pulley 4 and the pulley hook 6 are both slidably connected to the track 11, wherein the pulley hook 6 is arranged on a side of the pulley 4 away from the plug-in base 21. When in use, the pulley 4 and the pulley hook 6 are both used to hang curtains, and the transmission belt is driven by the transmission box 5 and the end transmission gear 3 to move, which can drive the pulley 4 to move, and the pulley 4 can push the pulley hook 6 to move.

[0042] like Figure 6 and 7As shown, the transmission box 5 also includes a connecting gear 52, which is arranged between the driving gear 51 and the end transmission gear 3, and meshes with the driving gear 51 and the end transmission gear 3 respectively. By setting the connecting gear 52, the power provided by the driving gear 51 can be transmitted to the end transmission gear 3. The curtain rail that is easy to transport is provided with a plurality of pulley hooks 6, and the pulley hooks 6 are sequentially arranged along the length direction of the track 11. Hanging curtains by using a plurality of pulley hooks 6 is more stable.
