Specific embodiments

[0022] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] As Figures 1-6 shown, a wire winder for a double-layer page curtain includes a track 1, a wire winding module 2 and a driving rod 3. The wire winding module 2 is arranged in the track 1, and a perforation 11 is formed in the bottom surface of the track 1;

[0024] The wire winding module 2 includes a base 20, a face cover 21, a first wire winding shaft 22 and a second wire winding shaft 23. An installation cavity is formed between the base 20 and the face cover 21. The first wire winding shaft 22 and the second wire winding shaft 23 are both arranged in the installation cavity. The first wire winding shaft 22 and the second wire winding shaft 23 are both penetrated by the driving rod 3. The first wire winding shaft 22 and the second wire winding shaft 23 are arranged side by side along a direction perpendicular to the length direction of the driving rod 3. The wire outlet 4 of the first wire winding shaft 22 and the wire outlet 4 of the second wire winding shaft 23 are both located in the gap between the first wire winding shaft 22 and the second wire winding shaft 23, and the wire outlet 4 of the first wire winding shaft 22 and the wire outlet 4 of the second wire winding shaft 23 pass through the same perforation 11. In this embodiment, the driving rod 3 is used to connect the driving end, and the driving end can be a motor to achieve rotation.

[0025] In the wire winder for the double-layer page curtain, by rotating the first wire winding shaft 22 or the second wire winding shaft 23 in the installation cavity, the actions of taking in or paying out the wire can be achieved, thereby driving the corresponding page curtain to rise or fall. Since the first wire winding shaft 22 and the second wire winding shaft 23 are arranged side by side along the direction perpendicular to the length direction of the driving rod 3, and the wire ends of the wire wound around the first wire winding shaft 22 and the wire ends of the wire wound around the second wire winding shaft 23 are both concentrated in the gap, and then pass through the same perforation 11 and are respectively connected to the corresponding page curtains. In this way, the number of openings on the track 1 can be reduced, thus simplifying the processing flow.

[0026] In this embodiment, the driving rod 3 is connected with two first wire winding shafts 22, and the wire outlets 4 of the two first wire winding shafts 22 are respectively connected to both sides of the page curtain; or the driving rod 3 is connected with two second wire winding shafts 23, and the wire outlets 4 of the two second wire winding shafts 23 are respectively connected to both sides of the page curtain.

[0027] It should be noted that, as Figure 4 and 5 shown, the wire winding module 2 further includes a connecting member 24. The connecting member 24 is arranged between the first wire winding shaft 22 and the second wire winding shaft 23 and is respectively connected to the first wire winding shaft 22 and the second wire winding shaft 23. The connecting member 24 is provided with a guiding hole 25, and the guiding hole 25 faces the perforation 11. The wire outlets 4 of the first wire winding shaft 22 and the second wire winding shaft 23 both pass through the guiding hole 25. By providing the connecting member 24, the gap between the first wire winding shaft 22 and the second wire winding shaft 23 can be kept unchanged, so as to ensure that the first wire winding shaft 22 and the second wire winding shaft 23 can rotate stably in the installation cavity. In addition, the guiding hole 25 on the connecting member 24 plays a role in guiding the wire outlets 4 of the first wire winding shaft 22 and the second wire winding shaft 23, and guiding the wire outlets 4 to the perforation 11.

[0028] Optionally, as Figure 4 and 5 shown, the wire winding module 2 further includes a tension roller 26, and the tension roller 26 is distributed at the outlet of the guiding hole 25. When the tension roller 26 is not provided, since the wire winding directions of the first wire winding shaft 22 and the second wire winding shaft 23 are the same, the wire outlet 4 of one wire winding shaft can smoothly enter the perforation 11, but the wire outlet 4 of the other wire winding shaft can only be forced into the perforation 11, resulting in the wire outlet 4 of this wire winding shaft being loose, and it is easy to have the phenomenon of wire jamming during winding or unwinding, as Figure 7As shown, in this embodiment, the wire 4 released from the first winding shaft 22 can smoothly enter the perforation, but the wire 4 released from the second winding shaft 23 can only be forced into the perforation 11. In this embodiment, after the tension roller 26 is provided, the wire 4 released from the first winding shaft 22 and the wire 4 released from the second winding shaft 23 pass through the guiding hole 25 and then contact the tension roller 26, so that the wire 4 is tightened to avoid the phenomenon of loose wire 4, and then penetrate into the perforation 11, thus facilitating the winding and unwinding of the first winding shaft 22 and the second winding shaft 23.

[0029] Preferably, as Figure 3 , 4 and Figure 5 show, the base 20 is provided with a limiting groove 201, a limiting hole 202 is provided at the bottom of the limiting groove 201, the limiting hole 202 faces the perforation 11, and the tension roller 26 is arranged in the limiting groove 201 so that the guiding hole 25 faces the limiting hole 202. After the first winding shaft 22 and the second winding shaft 23 are installed in the installation cavity, by providing the limiting groove 201 to accommodate the tension roller 26 and by providing the limiting hole 202 at the bottom of the limiting groove 201, the wire 4 released from the first winding shaft 22 and the wire 4 released from the second winding shaft 23 can pass through the base 20 and penetrate into the perforation 11.

[0030] Specifically, as Figure 3 , 4 and Figure 5 show, the winding module 2 further includes a guiding block 27, the guiding block 27 is connected to the connecting member 24, a sliding groove 203 is provided in the limiting groove 201, and the guiding block 27 is slidably arranged in the sliding groove 203. By the cooperation of the guiding block 27 and the sliding groove 203, the first winding shaft 22, the second winding shaft 23 and the connecting member 24 can be limited in the base 20.

[0031] Optionally, as Figure 4 and 5 show, the winding module 2 further includes a ferrule 28, the ferrules 28 are respectively arranged on both sides of the connecting member 24, and the first winding shaft 22 and the second winding shaft 23 are respectively arranged in their corresponding ferrules 28. In this embodiment, the ferrule 28 is fixedly connected to the connecting member 24, and the first winding shaft 22 and the second winding shaft 23 are both located in their corresponding ferrules 28 and can rotate relative to the ferrule 28.

[0032] Specifically, as Figure 2 shows, bearings 29 are sleeved on the ends of the first winding shaft 22 and the second winding shaft 23, and the outer walls of the bearings 29 are connected to the base 20. By providing the bearings 29, the first winding shaft 22 and the second winding shaft 23 can rotate relative to the base 20.

[0033] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
