DETAILED DESCRIPTION

[0020] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1-4 As shown, a curtain slide rail comprises a square tube assembly 1, a transmission box 2, an end transmission gear 4, a pulley 3 and a pulley hook 5, wherein the square tube assembly 1 is provided with a track 11;

[0022] like Figure 2 As shown, the transmission box 2 includes a driving gear 21 and a first transmission gear 22, the driving gear 21 is in transmission connection with the first transmission gear 22, the transmission box 2 is arranged on the side wall of the square tube component 1 and penetrates into the square tube component 1 from the side wall of the square tube component 1, so that the driving gear 21 is arranged outside the square tube component 1, and the first transmission gear 22 is arranged inside the square tube component 1;

[0023] The end transmission gear 4 is arranged in the square tube assembly 1, the first transmission gear 22 is transmission-connected with the end transmission gear 4 through a transmission belt, the pulley 3 is arranged between the first transmission gear 22 and the end transmission gear 4, the pulley 3 is slidably connected with the track 11, and the pulley 3 is connected with the transmission belt to pull the pulley 3 to move along the track 11;

[0024] The pulley hook 5 is slidably connected to the track 11 , and the pulley hook 5 is arranged on a side of the pulley 3 away from the end transmission gear 4 .

[0025] When in use, the pulley 3 and the pulley hook 5 are both used to hang curtains. The transmission belt is driven by the transmission box 2 and the end transmission gear 4 to move the pulley 3, and the pulley 3 can push the pulley hook 5 to move.

[0026] In the curtain slide rail, the transmission box 2 is set on the square tube assembly 1 and penetrates into the square tube assembly 1 from the side wall of the square tube assembly 1, which will not block the pulley 3 from pushing the pulley hook 5 to slide on the track 11 on the square tube assembly 1, so that the pulley hook 5 can slide to the end of the track 11 of the square tube assembly 1.

[0027] It is worth noting that the square tube assembly 1 includes a main square tube 12 and a secondary square tube 13, wherein the main square tube 12 is slidably connected to the secondary square tube 13, and the main square tube 12 is inserted into the secondary square tube 13. In this way, the secondary square tube 13 can move relative to the main square tube 12 to achieve contraction, so as to meet the installation requirements of curtains of different widths.

[0028] Optional, such as Figure 3 and 4 As shown, the secondary square tube 13 is provided with an escape opening 131, and the transmission box 2 is connected to the main square tube 12 after passing through the escape opening 131, so that the first transmission gear 22 is located inside the secondary square tube 13, and the driving gear 21 is located outside the secondary square tube 13. By providing the escape opening 131, when the secondary square tube 13 moves relative to the main square tube 12, the transmission box 2 can remain stationary and will not hinder the movement of the secondary square tube 13. If the transmission box 2 remains stationary, the transmission connection relationship between the first transmission gear 22 and the end transmission gear 4 can be maintained without being disconnected, and the pulley 3 can still keep moving after the secondary square tube 13 is extended or retracted.

[0029] Preferably, Figure 3 and 4 As shown, the first transmission gear 22 includes an upper tooth portion 221 and a lower tooth portion 222, which are coaxially arranged and connected, the upper tooth portion 221 is transmission-connected to the end transmission gear 4, and the lower tooth portion 222 is transmission-connected to the driving gear 21. The first transmission gear 22 plays a connecting role. On the one hand, it is used to connect with the driving gear 21 to keep the power source from being interrupted. On the other hand, it cooperates with the end transmission gear 4 to realize the operation of the transmission belt. If the upper tooth portion 221 and the lower tooth portion 222 are arranged, the transmission structure connected to the driving gear 21 and the transmission structure connected to the transmission belt can be separated.

[0030] Specifically, the transmission box 2 further includes a second transmission gear 23, which is disposed between the driving gear 21 and the first transmission gear 22 and is respectively meshed with the driving gear 21 and the first transmission gear 22. By providing the second transmission gear 23, the power provided by the driving gear 21 can be transmitted to the first transmission gear 22.

[0031] It is worth noting that the curtain rail is provided with a plurality of pulley hooks 5, and the pulley hooks 5 are sequentially arranged along the length direction of the track 11. It is more stable to hang curtains by using a plurality of pulley hooks 5.
