[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Example:

[0040] Reference Figure 1-11 An adjustable length curtain track device includes a slide rail 1, and further includes:

[0041] The first slider 11 is slidably connected to the outer wall of the slide rail 1. The slide rail 1 supports and limits the first slider 11, allowing the first slider 11 to slide along the slide rail 1, thereby pulling the curtain.

[0042] The first groove 12 is formed on the inner side of one end of the slide rail 1;

[0043] A connecting component is disposed inside the first groove 12, and its length is the same as the depth of the first groove 12, so that the connecting component is hidden by the first groove 12;

[0044] The second groove 13 is formed on the outer wall of the middle section of the slide rail 1;

[0045] An L-shaped through hole 15 is formed at the bottom of the second groove 13 and passes through the slide rail 1;

[0046] A position locking component is located on the inner side of the slide rail 1 at the end away from the first groove 12 and passes through the L-shaped through hole 15;

[0047] The slot 14 is formed at the bottom of the position locking component and engages with the locking end of the position locking component. The slot 14 provides a stress point for the position locking component.

[0048] The engaging component is located on the inner side of the slide rail 1 at the end away from the first groove 12 and is connected to the position locking component. The engaging component and the position locking component cooperate with each other to quickly connect two different sections of the slide rail 1.

[0049] The spring-loaded component is located on the outside of the locking component. The moving end is connected to the locking component, and the spring-loaded component supports and pushes the locking component.

[0050] The connecting assembly includes a support rod 2 fixed to the inner wall of the first groove 12. A locking head 21 is fixedly connected to the outer side of the support rod 2 away from the inner wall of the first groove 12, and the locking head 21 is supported and fixed by the support rod 2. A symmetrically arranged limiting rod 22 is fixedly connected to the outer wall of the locking head 21 near the support rod 2, and the limiting rod 2 supports and fixes the limiting rod 22 on both sides. A first spring 23 is slidably connected to the outer side of the limiting rod 22, and the first spring 23 is limited by the limiting rod 22. A guide block 24 is fixedly connected to the end of the first spring 23 away from the locking head 21. The guide block 24 is slidably connected to the support rod 2. The first spring 23 pushes the guide block 24 away from the locking head 21 with the locking head 21 as the stress point, and moves it along the support rod 2. Since the diameters on both sides of the support rod 2 are different, the position of the guide block 24 can be limited. The guide block 24 is slidably connected to the limiting rod 22, and the sliding angle of the guide block 24 is limited by the limiting rod 22.

[0051] The position locking assembly includes a rotating groove plate 5 slidably connected to the inside of the end of the slide rail 1 away from the first groove 12, which is limited by the slide rail 1. A locking plate 51 is rotatably connected to the inner side of the rotating groove plate 5, which is limited by the rotating groove plate 5, allowing the locking plate 51 to rotate within the rotating groove plate 5. A second locking rod 52 is fixedly connected to the top of the locking plate 51, supporting and fixing the second locking rod 52. A handle 53 is fixedly connected to the top of the second locking rod 52, which engages the handle. Hand 53 provides support and fixation. The locking plate 51 is engaged with the locking groove 14. By rotating the locking plate 51, it can tilt and engage with the locking groove 14, thereby limiting the position of the rotating groove plate 5. The second locking rod 52 is slidably connected to the L-shaped through hole 15. The second locking rod 52 slides in the L-shaped through hole 15, allowing it to move in two directions and providing space for the rotation of the locking plate 51. When the locking plate 51 is not engaged with the locking groove 14, the rotating groove plate 5 can move.

[0052] The engaging assembly includes a sliding sleeve 4 slidably connected to the inside of the end of the slide rail 1 away from the first groove 12. The slide rail 1 limits the sliding sleeve 4. The sliding sleeve 4 is fixedly connected to the rotating groove plate 5. The rotating groove plate 5 fixes the sliding sleeve 4, while simultaneously allowing the sliding sleeve 4 to move with the rotating groove plate 5. A symmetrically arranged first engaging rod 3 is rotatably connected to the inner wall of the sliding sleeve 4 on the side away from the rotating groove plate 5. The sliding sleeve 4 limits the first engaging rod 3, allowing the first engaging rod 3 to rotate inside the sliding sleeve 4. The first engaging rod 3 engages with the engaging head 21, thereby engaging the engaging head 21 and connecting the slide rails 1 on both sides. A fixing plate 31 is fixedly connected to the side of the first engaging rod 3 near the rotating groove plate 5, supporting and fixing the fixing plate 31. A second spring 32 is fixedly connected to the opposite side of the fixing plate 31. The second spring 32 uses the two fixing plates 31 as stress points, simultaneously exerting force on both sides. Pushing the fixing plate 31 causes the outer end of the first engaging rod 3 to rotate in opposite directions, thereby clamping and engaging the engaging head 21. When the rotating groove plate 5 drives the sliding sleeve 4 to continue moving towards the first groove 12, it will drive the first engaging rod 3 to move synchronously, so that the first engaging rod 3 passes through the guide block 24. Then, it pulls the two slide rails 1 to both sides simultaneously. By setting the stress of the second spring 32 to be greater than the stress of the first spring 23, the first engaging rod 3 can drive the guide block 24 to move synchronously and compress the first spring 23. After the guide block 24 and the engaging head 21 are in contact, the guide block 24 cannot move, so it supports the first engaging rod 3. At the same time, the first engaging rod 3 drives the fixing plate 31 to compress the second spring 32, so that the first engaging rod 3 moves outward at the end near the support rod 2, canceling the clamping of the guide block 24 and the engaging head 21, and completing the separation of the two slide rails 1.

[0053] The rebound assembly includes second sliders 41 fixedly connected to the outer walls of both sides of the sliding sleeve 4, which are supported and fixed by the sliding sleeve 4; stress plates 44 fixed to the inner sides of the slide rail 1 at the end away from the first groove 12, which are supported and fixed by the slide rail 1; a slide rod 43 fixedly connected to the outer wall of the stress plate 44 near the sliding sleeve 4, which is supported and fixed by the stress plate 44; a third spring 42 is provided on the outer side of the slide rod 43, and the second sliders 41 are slidably connected to the outer side of the third spring 42; one end of the second slider 41 is fixedly connected to the third spring 42, and the other end of the third spring 42 is fixedly connected to the stress plate 44; the third spring 42 pushes the second sliders 41 toward the rotating groove plate 5 with the stress plate 44 as the stress point, and the second sliders 41 drive the sliding sleeve 4 to move synchronously.

[0054] The slide rail 1 has evenly distributed O-shaped holes that can be used to quickly fix the slide rail 1 with screws.

[0055] Specifically, when using this adjustable length curtain track device:

[0056] During assembly: First, bring one end of the two slide rails 1 together with the engaging component and the connecting component respectively. Then, align the first engaging rod 3 with the engaging head 21 inside the first groove 12 and insert it. During the process, the engaging head 21 supports the first engaging rod 3, causing the end of the first engaging rod 3 away from the rotating groove plate 5 to move to both sides. After passing through the engaging head 21, since it is no longer supported by the engaging head 21, the end of the first engaging rod 3 away from the rotating groove plate 5 moves inward, completing the engagement of the engaging head 21 and simultaneously completing the assembly and connection of the two slide rails 1.

[0057] During disassembly: First, engage handle 53. Handle 53, through the second engaging rod 52, rotates the engaging plate 51, causing it to rotate out of the slot 14 and no longer engage with it. This allows the rotating slot plate 5 to move. Then, push handle 53 in a direction parallel to the slide rail 1. Handle 53, through the second engaging rod 52, moves the engaging plate 51 and the rotating slot plate 5 towards the sliding sleeve 4. Simultaneously, the rotating slot plate 5 moves the sliding sleeve 4 and the outer second slider 41 synchronously. The sliding sleeve 4, in turn, moves the first engaging rod 3, the fixing plate 31, and the second... Spring 32 also moves synchronously, and as the first engaging rod 3 continues to move, it receives support from the guide block 24, causing the first engaging rod 3 to move away from the rotating slot plate 5 and move to both sides to engage the guide block 24 in the same way. Then, the slide rails 1 on both sides are pulled to both sides at the same time. During this process, the first engaging rod 3 drives the guide block 24 to move synchronously and compresses the first spring 23. The guide block 24 supports the first engaging rod 3, causing the first engaging rod 3 to move to both sides at the same time, canceling the engagement between the guide block 24 and the engaging head 21, and pulling it out from the first groove 12.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
