[0032] Please refer to Figure 1 As shown, a specific embodiment of the present utility model provides a curtain 100, which includes a sheet body 20 and a linkable curtain rail 10, and the sheet body 20 is installed on the linkable curtain rail 10.

[0033] Refer to together Figure 2As shown, the linkable curtain rail 10 includes a rail 11, a plurality of bead devices A1 - A15, and a plurality of connection components B1 - B14. A sheet body 20 can be respectively installed on each bead device (any one of A1 - A15) so that the sheet body 20 can move along with the corresponding bead device.

[0034] Refer to together Figure 3 As shown, the bead devices A1 - A15 can move along the rail 11. Two adjacent bead devices are connected by one connection component.

[0035] Take Figure 2 As shown for example, from front to back, the plurality of bead devices include bead device A1, bead device A2, bead device A3, bead device A4,..., bead device A15, a total of 15 bead devices. Between bead device A1 and bead device A2, they are connected by a connection component B1. Between bead device A2 and bead device A3, they are connected by a connection component B2,..., between bead device A14 and bead device A15, they are connected by a connection component B14, a total of 14 connection components.

[0036] Continue to refer to Figure 3 As shown, the connection components B1 - B14 each respectively include a first electromagnet 131, a connecting rod 132, and a guide rail 133 (the guide rail 133 can specifically be a guide hole). The first electromagnet 131 is connected to the bead device in the front, the guide rail 133 is connected to the bead device in the back, the connecting rod 132 is slidably connected to the guide rail 133. One end of the connecting rod 132 facing the first electromagnet 131 is provided with a magnetizable part 1321, and the magnetizable part 1321 is aligned with the first electromagnet 131 in the front - back direction. The other end of the connecting rod 132 facing away from the first electromagnet 131 is provided with a limiting part (see Figure 2 , and the limiting part can specifically be a block provided at the end of the connecting rod 132 with a cross - sectional area larger than the guide hole 133).

[0037] Specifically, the first electromagnet 131 of the connecting component B1 is arranged on the ball running device A1, the guide rail 133 of the first electromagnet 131 of the connecting component B1 is arranged on the ball running device A2, the connecting rod 132 of the connecting component B1 is slidably connected with the guide rail 133 of the connecting component B1, and one end of the connecting rod 132 of the connecting component B1 facing the first electromagnet 131 of the connecting component B1 is provided with a magnetizable part 1321 (such as a magnet or an iron sheet). The magnetizable part 1321 is aligned with the first electromagnet 131 of the connecting component B1 in the front-back direction. One end of the connecting rod 132 of the connecting component B1 facing away from the first electromagnet 131 of the connecting component B1 is provided with a limiting part, and the function of the limiting part is to prevent the connecting rod 132 from disengaging from the guide rail 133 when sliding relative to the guide rail 133. That is, when the connecting rod 132 slides to a certain distance, the guide rail 133 will be pulled by the limiting part and then the ball running device A2 will be pulled.

[0038] Similarly, the first electromagnet 131 of the connecting component B2 is arranged on the ball running device A2, the guide rail 133 of the first electromagnet 131 of the connecting component B2 is arranged on the ball running device A3, the connecting rod 132 of the connecting component B2 is slidably connected with the guide rail 133 of the connecting component B2, and one end of the connecting rod 132 of the connecting component B2 facing the first electromagnet 131 of the connecting component B2 is provided with a magnetizable part 1321. The magnetizable part 1321 is aligned with the first electromagnet 131 of the connecting component B2 in the front-back direction. One end of the connecting rod 132 of the connecting component B2 facing away from the first electromagnet 131 of the connecting component B2 is provided with a limiting part. And so on.

[0039] When only one ball running device is needed, the first electromagnet 131 of the connecting component B1 connecting the ball running device A1 and the ball running device A2 can be disconnected, so that the connecting rod 132 of the connecting component B1 will not be attracted by the first electromagnet 131. When the ball running device A1 is moved, the ball running device A2 will not move along with the ball running device A1.

[0040] When two ball running devices are needed, the first electromagnet 131 of the connecting component B1 connecting the ball running device A1 and the ball running device A2 can be turned on, so that the connecting rod 132 of the connecting component B1 is attracted by the first electromagnet 131, and the first electromagnet 131 of the connecting component B2 connecting the ball running device A2 and the ball running device A3 can be disconnected, so that the connecting rod 132 of the connecting component B2 will not be attracted by the first electromagnet 131. When the ball running device A1 is moved, the connecting rod 132 between the ball running device A1 and the ball running device A2 will be pulled. After the connecting rod 132 moves to a certain distance, the ball running device A2 will be continuously pulled by the limiting part, but the ball running device A3 will not be driven to move. And so on. When more ball running devices need to move, the on-off of the corresponding first electromagnet 131 can be controlled, so that the number of ball running devices to be moved can be freely selected.

[0041] It can be understood that in other embodiments, the first electromagnet 131 may be connected to the rear ball device, and the guide rail 133 is connected to the front ball device.

One end of the connecting rod 132 close to the first electromagnet 131 is provided with a magnetizable part 1321, and the magnetizable part 1321 is aligned with the first electromagnet 131 in the front-rear direction. A limiting part is provided at the end of the connecting rod 132 facing away from the first electromagnet 131.

[0042] Continue to refer to Figure 3 As shown, a first positioning structure 1322 is provided on the connecting rod 132, and a second positioning structure (not specifically shown) that cooperates with the first positioning structure 1322 is provided on the guide rail 133. The first positioning structure 1322 and the second positioning structure cooperate to limit the connecting rod 132 to move back and forth, so as to prevent the connecting rod 132 from rotating during the movement, so that the magnetizable part 1321 can ensure accurate alignment with the first electromagnet 131.

[0043] Refer to Figure 2 and Figure 3 As shown, the linkable curtain guide rail 10 may further include a first transmission component 14. The first transmission component 14 is used to drive the ball device to move forward or backward. Specifically, the first transmission component 14 includes a plurality of first connection structures 141, a transmission structure 142, and a second connection structure 143. Among them, one of the ball devices is provided with one of the first connection structures 141, and the second connection structure 143 is provided on the transmission structure 142. The transmission structure 142 drives the second connection structure 143 to move back and forth, and the second connection structure 143 is used to selectively connect with one of the first connection structures 141.

[0044] In this embodiment, the second connection structure 143 is a belt, and the second connection structure 143 is fixed to the belt.

[0045] It is possible that the transmission structure 142 drives the second connection structure 143 to move to the position corresponding to the ball device A1, the first connection structure 141 is connected to the second connection structure 143, and then the transmission structure 142 drives the second connection structure 143 to move, thereby driving the ball device A1 to move.

[0046] In this embodiment, the first connection structure 141 is a magnetizable structure (such as a magnet or an iron sheet), and the second connection structure 143 is a second electromagnet. When the second connection structure 143 moves to the position corresponding to the ball device A1, the second electromagnet is turned on to attract the first connection structure 141.

[0047] In other embodiments, the first connection structure 141 may be a jack, and the second connection structure 143 may include a first driver and a plug. The first driver is configured to drive the plug to move so that the plug is inserted into or withdrawn from the jack. After the plug is inserted into the jack, the first connection structure 141 is connected and cooperated with the second connection structure 143, and when the plug is withdrawn from the jack, the first connection structure 141 and the second connection structure 143 lose cooperation.

[0048] Refer to Figures 4 - 6 As shown, the linkable curtain rail 10 may further include a second transmission assembly 15. The second transmission assembly 15 is configured to rotate the sheet body 20 connecting the bead device. Specifically, the second transmission assembly 15 includes a second driver 151, a transmission bar 152, a plurality of worms 153, and a plurality of worm wheels 154. Among them, the transmission bar 152 has a first positioning portion 1521 provided along its length direction (refer to Figure 6 ), the transmission bar 152 is connected to the second driver 151, and the second driver 151 is configured to drive the transmission bar 152 to rotate. The worm 153 is slidably disposed on the transmission bar 152, and the worm 153 is provided with a second positioning portion 1531 that cooperates with the first positioning portion 1521 (refer to Figure 6 ), and one worm 153 is connected to one bead device (any one of A1 - A15). One worm wheel 154 is in transmission connection with one worm 153. Thus, the worm 153 can move back and forth along the transmission bar 152. After selecting an appropriate number of bead devices and starting the second driver 151 to drive the transmission bar 152 to rotate, with the cooperation of the first positioning portion 1521 and the second positioning portion 1531, it will drive a plurality of the worms 153 to rotate synchronously, and further drive a plurality of the worm wheels 154 to rotate, so as to realize the rotation of the sheet body 20 connected to the worm wheel 154 to realize the opening and closing of the sheet body 20.

[0049] The first positioning portion 1521 may be a rib or a groove, and the second positioning portion 1531 may be a groove paired with the rib or a rib paired with the groove.

[0050] Refer to Figure 6 As shown, the bead devices A1 - A15 may further be provided with pulleys 16, and the pulleys 16 slide in the track 11 to facilitate the sliding of the bead devices A1 - A15 in the track 11.
