This structure increases the functionality inside the inner rail profile 300 and facilitates the installation of other components in the transmission mechanism.

[0042] Specifically, the first beam body 310 includes a first top side panel A311 and a first front side panel A312, the first top side panel A311 is parallel to and opposite to the first top side panel B3311, and the second channel 3002 is defined therebetween. The second beam body 320 includes a first bottom side panel A321 and a first front side panel B322, the first bottom side panel A321 is parallel to and opposite to the first bottom side panel B3312, and the third channel 3003 is defined therebetween.

To be precise, the first guide assembly 800 is fixedly connected to the inner rail profile 300, and the inner rail profile 300 can drive the first guide assembly 800 to move synchronously when it is active; the second guide assembly 900 is fixedly connected to the outer rail profile 400, and the outer rail profile 400 can drive the second guide assembly 900 to move synchronously when it is active.

[0049] Furthermore, when the inner rail profile 300 moves toward a direction away from the outer rail profile 400, the distance between the first guide assembly 800 and the second guide assembly 900 is shortened; when the inner rail profile 300 moves toward a direction close to the outer rail profile 400, the distance between the first guide assembly 800 and the second guide assembly 900 is increased.

[0051] See also Figure 9-10 The transmission mechanism includes a driving wheel 11, a driven wheel 12, a conveyor belt 13, a first steering wheel 14 and a second steering wheel 15. The driving wheel 11 is installed in the first fixed seat 100, and the driven wheel 12 is installed in the second fixed seat 200. The driving wheel 11 is connected to a driving device, which can be but is not limited to a motor. The driving device provides rotational power for the driving wheel 11 to rotate.

The positioning wheel 16 is provided to make the transmission process of the conveyor belt 13 smoother, to avoid the contact between the conveyor belt 13 and the first slider 810 as much as possible, and to reduce the resistance of the conveyor belt 13.

[0053] See also Figure 11-Figure 12 The first pulley assembly 500 includes two first sliders 510 and a first curtain hanging member 520. The two first sliders 510 are plug-in connected to the first curtain hanging member 520. The first slider 510 is provided with a first clamping opening 511 and a locking head 512, and the first curtain hanging member 520 is provided with a first locking opening 521. The locking heads 512 of the two first sliders 510 are plugged into the first locking opening 521 to connect the two ends of the conveyor belt 13.

[0054] See also Figure 13-Figure 14 The second pulley assembly 600 includes a second slider 610, a pressing member 620 and a second curtain member 630. A second clamping opening 611 is provided between the second slider 610 and the pressing member 620. The conveyor belt 13 passes through the second clamping opening 611. The second curtain member 630 is provided with a second locking opening 631. When the pressing member 620 and the second slider 610 are both connected to the second locking opening 631, the second clamping opening 611 is closed, and the conveyor belt 13 is engaged by the pressing member 620 and the second slider 610, so that the second pulley assembly 600 is fixed on the conveyor belt 13; on the contrary, when the pressing member 620 and the second slider 610 are separated from the second locking opening 631, the second pulley assembly 600 is disconnected from the conveyor belt 13.

[0055] See also Fig.15, the conveyor belt 13 forms a closed loop process: after the conveyor belt 13 is connected to the driving wheel 11, one end of the conveyor belt 13 penetrates into the top side of the sixth channel 4001 of the outer rail profile 400 and is connected to one of the first sliders 510; the other end penetrates into the bottom side of the sixth channel 4001 of the outer rail profile 400, and then connects to the positioning wheel 16 on the first slider 810, and then enters the top side of the first channel 3001 of the inner rail profile 300, and then connects to the second steering wheel 15, makes the first steering, and then enters the bottom side of the first channel 3001 of the inner rail profile 300, and then returns to the first The slider 810 is connected to the first steering wheel 14, making a second turn, and then entering the third channel 3003 of the inner rail profile 300, connecting with the second slider 610 on the second pulley assembly 600 in this channel, and then connecting with the driven wheel 12, entering the second channel 3002 of the inner rail profile 300, and finally entering the top side of the sixth channel 4001 of the outer rail profile 400, and connecting with another first slider 510, and finally merging the two first sliders 510 together through the first curtain hanging member 520 to realize the closed-loop connection of the conveyor belt 13.

[0056] In this technical solution, the track is retracted by the inner track profile 300 sliding relative to the outer track, thereby adjusting the length of the track to adapt to different installation environments. In addition, the retractable track facilitates packaging and transportation, and also enables the track to be reused.

[0057] Furthermore, in the technical solution: in order for the conveyor belt 13 to adapt to the expansion and contraction of the track, the first steering wheel 14 and the second steering wheel 15 are introduced into the track to realize the retraction and extension of the conveyor belt 13. In simple terms, when the length of the track is extended, the first steering wheel 14 and the second steering wheel 15 are close to each other, thereby releasing the conveyor belt 13 between the first steering wheel 14 and the second steering wheel 15, so that the conveyor belt 13 can adapt to the extension of the track. On the contrary, when the length of the track is shortened, the first steering wheel 14 and the second steering wheel 15 are separated from each other, and the length of the conveyor belt 13 between the first steering wheel 14 and the second steering wheel 15 is extended, so that the conveyor belt 13 can adapt to the extension of the track.

[0058] Furthermore, in the present technical solution, the first pulley assembly 500 and the second pulley assembly 600 can maintain symmetrical sliding on the track, so that the expansion / contraction amplitude of the curtains on the left and right sides can be kept consistent. When the track is extended and retracted, the distance between the conveyor belt 13 between the first pulley assembly 500 and the second pulley assembly 600 needs to be adjusted so that the first pulley assembly 500 and the second pulley assembly 600 can maintain the same stroke on the track. However, since the two ends of the conveyor belt 13 are connected on the first pulley assembly 500 to form a closed loop, the position of the first pulley assembly 500 on the conveyor belt 13 is always unchanged, so it is necessary to adjust the position of the second pulley assembly 600 on the conveyor belt 13, and then adjust the distance between the conveyor belt 13 between the first pulley assembly 500 and the second pulley assembly 600. As for how to adjust the connection between the second pulley assembly 600 and the conveyor belt 13, please refer to paragraph 0056 for details, which will not be repeated here.
