Description

Technical Field

[0001] This utility model relates to the field of electric curtain track technology, and more specifically, to an electric curtain track with adjustable length. Background Technology

[0002] Automatic curtains are also called motorized curtains. Automatic curtains are divided into fully automatic curtains and semi-automatic curtains. Fully automatic curtains are based on sunlight and temperature, and automatically open and close the curtains when the set light and temperature conditions are met. Semi-automatic curtains do not require you to walk to the window to manually pull the curtains; you can operate them with a handheld remote control device, such as a smartphone or a device similar to a TV remote control.

[0003] Electric curtain tracks are an important component of electric curtains. However, the length of electric curtain tracks on the market is not adjustable, and window sizes vary. This requires professionals to measure the window size in advance, and the factory to customize the curtain tracks according to the measured size. This makes it impossible to mass-produce electric curtain tracks, affecting the factory's production efficiency. At the same time, because electric curtain tracks are long and not adjustable, they are also inconvenient to transport, resulting in certain defects in use.

[0004] In view of this, we propose a motorized curtain track with adjustable length. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] An adjustable-length motorized curtain track includes a main track 1. Two sets of movable tracks 2 are movably inserted into the inner side of the main track 1, each set extending through the main track 1 to both sides. A connecting block 3 is fixedly installed on the outer side of each movable track 2. A fixing block 4 is fixedly installed on the outer side of the connecting block 3. A movable block 5 is movably inserted into the inner side of the fixing block 4, extending through the fixing block 4 to the outer side. A locking block 6 is fixedly installed on the outer side of the movable block 5, located outside the fixing block 4. Multiple sets of locking teeth are fixedly installed on the outer side of the locking block 6. A positioning plate 8 is fixedly installed on the outer side of the main track 1, with multiple sets of mating clips on the outer side of the positioning plate 8. The toothed groove has a spring 7 inside the fixed block 4. One end of the spring 7 is connected to the fixed block 4, and the other end is connected to the movable block 5. The spring 7 does not deform in the initial state. When adjusting the movable track 2, the locking block 6 needs to be moved to separate from the positioning plate 8. When the locking block 6 moves, it will drive the movable block 5 to move and squeeze the spring 7. At this time, the spring 7 deforms. After adjusting the position of the movable track 2, the locking block 6 is released. At this time, the elastic potential energy of the spring 7 is released, which can drive the locking block 6 to quickly fit into the positioning plate 8. This facilitates the adjustment of the movable track 2 while ensuring the installation stability of the movable track 2.

[0029] Specifically, two sets of rotating rods 9 are rotatably arranged inside the movable track 2. A first pulley 10 is fixedly arranged on the outer side of each set of rotating rods 9. An installation block 11 is movably arranged inside the movable track 2. A second rotating rod 12 is rotatably arranged inside the installation block 11. A second pulley 13 is fixedly arranged on the outer side of the second rotating rod 12. A belt 14 is sleeved on the outer side of the first pulley 10 and the second pulley 13. The second pulley 13 can store a portion of the belt 14, so that the belt 14 can be extended or shortened when adjusting the position of the movable track 2, thereby facilitating its use in conjunction with the movable track 2.

[0030] Furthermore, limit blocks 16 are fixedly installed on both sides of the movable track 2, and limit grooves 17 for docking with the limit blocks 16 are opened on both sides of the main track 1. When the movable track 2 moves, it drives the limit blocks 16 to slide within the limit grooves 17, thereby further ensuring the stability of the movable track 2 in use.

[0031] It is worth noting that an L-shaped block 18 is fixedly installed on the outside of the mounting block 11. The L-shaped block 18 moves through the main track 1 and extends to the outside. A fixing frame 19 is fixedly installed on the outside of the main track 1 to engage the L-shaped block 18. The L-shaped block 18 slides within the fixing frame 19, thereby facilitating the adjustment of the position of the second pulley 13 so that it can tighten the belt 14 for use.

[0032] It is worth noting that a threaded rod 20 is fixedly installed on the outer side of the L-shaped block 18. The threaded rod 20 movably passes through the fixed frame 19 and extends to the outside. A wing nut 21 is threaded on the outer part of the threaded rod 20 located outside the fixed frame 19. A through groove 22 for engaging the threaded rod 20 is opened through the outer side of the fixed frame 19. By loosening or tightening the wing nut 21, the second pulley 13 can be moved and positioned easily, thereby ensuring the stability of the belt 14 in use.

[0033] In addition, a gripping groove 23 is provided on the outer side of the card block 6. By setting the gripping groove 23, the card block 6 can be moved easily, improving the ease of operation.

[0034] Working principle: First, according to the size of the window, pull the locking block 6 outward to separate it from the positioning plate 8. Then, move the movable track 2 inward or outward to the main track 1. When the movable track 2 moves, it drives the connecting block 3 and the fixing block 4 to move. The movement of the fixing block 4 drives the movable block 5 and the locking block 6 to move. After the movable track 2 is moved to the appropriate position, release the locking block 6. At this time, the rebound force of the spring 7 can drive the locking block 6 to stick to the positioning plate 8, thereby fixing the movable track 2. At the same time, when the movable track 2 moves, it can drive the rotating rod 9 and the first pulley 10 to move. When the first pulley 10 moves, it stretches or contracts the belt, thereby matching the length of the track for use. Then, move the mounting block 11 to the appropriate position, which can drive the second pulley 13 to tighten the belt 14. Finally, tighten the wing nut 21 to ensure the stability of the belt 14.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
