[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0032] Example 1

[0033] Please refer to Figure 1-6 As shown, an electric curtain cord retractable mechanism includes a transmission box 1, a connecting box 2 is fixedly connected to the right side of the transmission box 1, a sliding box 3 is slidably connected to the right side of the connecting box 2, and the sliding box 3 is fixedly connected to the fixed box 4 at one end away from the connecting box 2. A transmission mechanism 5 is provided in the transmission box 1, and a slide groove 202 is opened on one side of the connecting box 2. The sliding box 3 is slidably connected to the connecting box 2 through the slide groove 202.

[0034] In this embodiment, first, the sliding box 3 is slid according to the size of the customer's window. The sliding box 3 can freely expand and contract through the slide groove 202, which can ensure that the overall size of the connecting box 2 and the sliding box 3 is adapted to the length of the customer's window. At the same time, the rope 506 in the wire reel 505 is pulled to the corresponding position as the sliding box 3 is pulled. This not only allows for the rapid installation of customized finished curtain rails, but also solves the problem of dimensional deviation of the curtain rails. Even if there is a measurement error, the width of the track can be freely adjusted according to the actual situation on site, reducing the after-sales rate. Secondly, the transmission mechanism 5 can provide driving force for the opening and closing of the curtains, making the entire curtain track easy to install, improving installation efficiency, and further expanding the practicality and adaptability of the present utility model.

[0035] Example 2

[0036] Please refer to Figure 1-5 As shown, the transmission mechanism 5 includes a driving module 501, which is mounted on the bottom of the transmission box 1. A slot 101 is provided at the bottom of the transmission box 1. The output end of the driving module 501 extends to the inside of the transmission box 1 through the slot 101 and is fixedly connected to a main gear 502. Two sets of rotating columns 503 are rotatably connected inside the transmission box 1. The tops of the two sets of rotating columns 503 are fixedly connected to slave gears 504. The two slave gears 504 are meshed with the main gear 502. The outer surfaces of the two sets of rotating columns 503 are fixedly connected to wire reel disks 505. A wire rope 506 is wound around the left wire reel disk 505. A fixed column 508 is fixedly connected to the fixed box 4. A fixed disk 509 is fixedly connected to the upper side of the fixed column 508. The wire rope 506 extends out of the left wire reel disk 505, passes around the inside of the fixed disk 509 and is fixedly connected to the inside of the right wire reel disk 505. The front and back sides of the wire rope 506 are fixedly connected to buckles 507.

[0037] 506 is fixed to the inside of the right wire winding wheel 505, and then the two buckles 507 are engaged with the relative positions of the wire rope 506. At this time, the driving module 501 is started to drive the main gear 502 to rotate, which in turn can drive the two sets of meshing wire winding wheels 505 to rotate. When the driving module 501 drives the main gear 502 to rotate forward, the buckles 507 on both sides can be moved away from each other, and the curtain is opened. When the driving module 501 drives the main gear 502 to rotate backward, the buckles 507 on both sides are moved closer to each other, and the curtain is closed. This not only makes opening and closing of the curtain more convenient, but also replaces the transmission belt of the traditional electric curtain track with the wire rope 506, saving material cost, improving labor efficiency and reducing labor cost.

[0038] Example 3

[0039] Please refer to Figure 6 As shown, two opposite sides of the bottom of the connection box 2 are provided with through slots 201, and two opposite sides of the bottom of the sliding box 3 are also provided with connecting slots 301. The through slots 201 and the connecting slots 301 are adapted in size, and the buckles 507 are slidably connected to both the through slots 201 and the connecting slots 301.

[0040] In this embodiment, the two buckles 507 are driven by the cord 506 to move away from and approach each other, and then the curtain (not shown in the figure) engaged by the buckle 507 can be driven to move through the through slot 201 and the connecting slot 301, thereby completing the opening and closing of the curtain. The buckle 507 is also slidably connected to the through slot 201 and the connecting slot 301, further enhancing the stability of the movement of the buckle 507.

[0041] The working principle and usage process of this device: First, slide the sliding box 3 according to the size of the customer's window. The sliding box 3 can freely expand and contract through the sliding groove 202 to ensure that the overall size of the connecting box 2 and the sliding box 3 is adapted to the length of the customer's window. At the same time, the rope 506 in the wire reel 505 is pulled to the corresponding position as the sliding box 3 is pulled out. Not only can the customized finished curtain rails be quickly installed, but also the problem of size deviation of the curtain rails can be solved. Even if the measurement is wrong, the width of the track can be freely adjusted according to the actual situation on site, reducing the after-sales rate. Secondly, the main gear 502 on the output rod of the drive module 501 is slid into the interior of the transmission box 1 through the bottom notch 101 of the transmission box 1, and then the rope 506 wound in the left wire reel 505 is passed through the fixed disk. 509, and then the cord 506 is fixed to the inside of the right winding wheel 505, and then the two buckles 507 are engaged with the relative position of the cord 506. At this time, the driving module 501 is started to drive the main gear 502 to rotate, and then the two sets of meshing winding wheels 505 can be driven to rotate. When the driving module 501 drives the main gear 502 to rotate forward, the buckles 507 on both sides can be moved away from each other, and then the curtain is opened. When the driving module 501 drives the main gear 502 to reverse, the buckles 507 on both sides are close to each other, and then the curtain is closed. Not only does it make the opening and closing of the curtain more convenient, but the cord 506 also replaces the transmission belt of the traditional electric curtain track, saving material costs, improving labor efficiency and reducing labor costs.
