Abstract
Description
Technical Field
[0001] The present application relates to the field of curtain accessories, and in particular to a roller blind controller. Background Art
[0002] Currently, roller blinds are made by rolling the curtain into a drum and raising or lowering it with a pull cord or zipper to block sunlight and block outside vision. Existing roller blind controllers all include a pull cord, a pull cord pulley, and a rotating drum connected to the curtain reel. Pulling the pull cord causes the curtain to be rolled up or down, or lowered or lowered.
[0003] Regarding the above-mentioned related technologies, there are still defects: when the user pulls the pull cord, the cord buckle will slide in the shell. As the roller blind is used for a long time, the friction between the cord buckle and the rope becomes increasingly severe, and the cord buckle is prone to wear and damage. Once the cord buckle of the existing roller blind is damaged, the user will remove and replace the entire roller blind due to the difficulty in installing the cord buckle, which causes waste. Therefore, there is room for improvement. Utility Model Content
[0004] In order to facilitate the replacement of damaged cord buckles and extend the service life of roller blinds, this application provides a roller blind controller.
[0005] The roller shutter controller provided in this application adopts the following technical solutions:
[0006] A roller shutter controller includes a shell, a cord lock and a rotating wheel. The cord lock is slidably connected to the shell, and an adjustment space for the pull rope to pass through is formed between the cord lock and the rotating wheel. The shell is provided with an adjustment cavity for the rope lock to slide. The adjustment cavity includes an inclined cavity and a vertical cavity connected to the inclined cavity. When the cord lock slides in the inclined cavity, the width of the adjustment space changes; when the cord lock slides in the vertical cavity, the width of the adjustment space remains unchanged. A displacement rod is integrally formed on the cord lock, and a telescopic rod is slidably connected to the displacement rod, and the displacement rod is tightly attached to the inner wall of the adjustment cavity; the end of the displacement rod is rotatably connected to a limiting plate, and an adjustment spring is connected between the limiting plate and the displacement rod, and the limiting plate always has a tendency to move toward the telescopic rod; the end diameter of the telescopic rod gradually decreases.
[0007] By adopting the above technical solution, when the limiting plate rotates out of the edge of the displacement rod, the position of the displacement rod can be fixed by the limiting plate and the rope buckle. Since the position of the displacement rod is fixed, the position of the rope buckle will also remain fixed. If the rope buckle needs to be replaced, it is only necessary to move the telescopic rod so that the limiting plate retracts to a position not exceeding the edge of the displacement rod, and then the rope buckle and the displacement rod can be removed from the shell.
[0008] Optionally, the rope buckle is connected to a cover plate for rotation on the side away from the limiting plate, and a displacement cavity for sliding of the telescopic rod is opened in the rope buckle and the displacement rod. When the cover plate covers the cavity opening of the displacement cavity, the limiting plate can exceed the end edge of the telescopic rod.
[0009] By adopting the above technical solution, the cover plate blocks the cavity opening of the displacement cavity, so that the telescopic rod always remains in the position of passing through the displacement cavity, and at the same time the limit plate can always be located on the other side of the shell, and the limit plate and the rope buckle always keep the displacement rod clamped.
[0010] Optionally, a return spring is connected to the displacement rod, and the return spring is wound around the rod body of the telescopic rod, so that the telescopic rod always has a tendency to move in a direction away from the limiting piece.
[0011] By adopting the above technical solution, when the user needs to replace the cord buckle, the cover plate is directly rotated to expose the cavity opening of the displacement cavity, and the telescopic rod can be automatically moved by the reset spring to automatically retract the telescopic rod into the displacement cavity.
[0012] Optionally, a plurality of anti-slip grooves are arranged in an array on one side of the cover plate facing away from the displacement cavity.
[0013] By adopting the above technical solution, the anti-slip pattern increases the friction between the user's hand and the cover plate, making it easier for the user to slide the cover plate when replacing the cord buckle.
[0014] Optionally, a magnetic component is integrally formed on the edge of the cord lock, and the magnetic component can be magnetically connected to the cover plate.
[0015] By adopting the above technical solution, the magnetic part magnetically attracts the cover plate, so that the cover plate can relatively stably seal the cavity opening of the displacement cavity. When the pull rope is pulled or the rope buckle is shaking, the position of the cover plate is not easy to change.
[0016] Optionally, a sponge layer is further provided inside the rotating wheel.
[0017] By adopting the above technical solution, when the rope buckle and the rotating wheel clamp the pull rope, the sponge can increase the friction force on the pull rope, and the sponge can protect the rotating wheel to extend the service life of the rotating wheel.
[0018] To sum up, the beneficial technical effect included in the present application is that when the limit plate rotates out of the edge of the displacement rod, the position of the displacement rod can be fixed by the limit plate and the rope buckle. Since the position of the displacement rod is fixed, the position of the rope buckle will also remain fixed. If the rope buckle needs to be replaced, it is only necessary to move the telescopic rod so that the limit plate retracts to no more than the edge of the displacement rod, and then the rope buckle and the displacement rod can be removed from the shell.

[0024] The following is combined with Figure 1-4 This application is described in further detail.
[0025] The embodiment of the present application discloses a roller shutter controller. Figure 1 、 Figure 2 A roller shutter controller includes a housing 1, a cord lock 2 mounted on the housing 1, and a rotating wheel 3. A connector is provided on the rotating wheel 3 for connecting the housing 1 and the roller shutter. The cord lock 2 and the rotating wheel 3 are not in close contact, and an adjustment space 4 is provided between the two. The pull rope is provided with a layer on the rotating wheel 3 and passes through the adjustment space 4 and the bottom of the cord lock 2 to exit the housing 1. An adjustment cavity 5 for the cord lock 2 to slide is also provided on the housing 1. The adjustment cavity 5 includes an inclined cavity 6 and a vertical cavity 7, and the inclined cavity 6 is connected to the end of the vertical cavity 7.
[0026] When the user pulls the pull cord, if the cord lock 2 slides in the inclined cavity 6 and moves toward the rotating wheel 3, the width of the adjustment space 4 will be reduced, and the pull cord between the cord lock 2 and the rotating wheel 3 will be clamped by the cord lock 2 and the rotating wheel 3, thereby stopping the roller blind.
[0027] If the user needs to continue rotating the roller blind, he can swing the pull cord in the opposite direction to move the cord buckle 2 away from the rotating wheel 3, thereby increasing the distance of the adjustment space 4, and release the squeeze on the pull cord until the cord buckle 2 slides into the upright cavity 7. At this time, the pull cord is restored to its function of adjusting the movement of the roller blind.
[0028] Reference Figure 1 、 Figure 3In the direction of the rope lock 2 toward the shell 1, a displacement rod 8 that can slide in the adjustment cavity 5 is also integrally formed. A displacement cavity 14 is opened in the rope lock 2, and the displacement cavity 14 passes through the rope lock 2 and the displacement rod 8. A telescopic rod 9 is also provided in the displacement cavity 14, and the telescopic rod 9 can slide along the opening length of the displacement cavity 14. When the displacement rod 8 slides in the displacement cavity 14, both sides of the rod body of the displacement rod 8 are in close contact with the inner cavity wall of the adjustment cavity 5. A limiting plate 10 is also connected to the end of the displacement rod 8 inserted into the adjustment cavity 5. The limiting plate 10 and the displacement rod 8 are connected by an adjusting spring 11. The adjusting spring 11 makes the limiting plate 10 always have a tendency to move toward the telescopic rod 9. The diameter of the end of the telescopic rod 9 is getting smaller and smaller. When the end of the telescopic rod 9 does not pass through the displacement cavity 14, the limiting plate 10 is acted upon by the adjusting spring 11, and the end of the limiting plate 10 away from the telescopic rod 9 does not exceed the outer edge of the displacement rod 8. When the telescopic rod 9 is pushed beyond the displacement cavity 14, as the diameter of the telescopic rod 9 reaches its maximum, the limiting piece 10, pushed by the telescopic rod 9, extends away from the telescopic rod 9 and gradually extends beyond the outer edge of the displacement rod 8 to contact the housing 1. The limiting piece 10 and the cord lock 2 interact to keep the displacement rod 8 in the adjustment cavity 5, thereby securing the cord lock 2.
[0029] Reference Figure 3 、 Figure 4 A cover plate 13 is rotatably connected to the end of the cord lock 2 away from the limiting plate 10. The shape of the cover plate 13 mirrors the side profile of the cord lock 2. After the user pushes the telescopic rod 9 to open the limiting plate 10, the user can rotate the cover plate 13 to block the opening of the displacement chamber 14. This prevents the telescopic rod 9 from ejecting from the opening on the side of the cord lock 2, and ensures that the limiting plate 10 remains beyond the edge of the displacement rod 8. A magnetic member 16 is also integrated into the edge of the cord lock 2 to magnetically connect the cover plate 13. This magnetic member 16 secures the cover plate 13, ensuring its stability.
[0030] Reference Figure 3 A return spring 12 is also installed within the displacement rod 8 and is wound around the telescopic rod 9. This return spring 12 ensures that the telescopic rod 9 always tends to move away from the housing 1. If the user discovers that the cord lock 2 is damaged, they can simply slide the cover 13 so that it no longer covers the opening of the displacement cavity 14. The return spring 12 will then cause the telescopic rod 9 to move away from the housing 1. As the telescopic rod 9 moves, the stopper 10 will also move toward the telescopic rod 9, retracting to the edge of the displacement rod 8. The user can then remove the cord lock 2 and the displacement rod 8 from the housing 1.
[0031] When the user needs to slide the cover 13, a plurality of anti-slip grooves 15 are arranged on the side of the cover 13 away from the displacement cavity 14. The anti-slip grooves 15 increase the friction of the hand on the cover 13, making it easier to push the cover 13.
[0032] Reference Figure 1 A sponge layer 17 is also provided inside the rotating wheel 3. When the rope buckle 2 and the rotating wheel 3 clamp the pull rope, the sponge can increase the friction force on the pull rope, and protect the rotating wheel 3 through the sponge, thereby extending the service life of the rotating wheel 3.
[0033] The embodiment of the present application discloses an implementation principle of a roller shutter controller: when the limiting plate 10 rotates out of the edge of the displacement rod 8, the position of the displacement rod 8 can be fixed by the limiting plate 10 and the rope buckle 2. Since the position of the displacement rod 8 is fixed, the position of the rope buckle 2 will also remain fixed. If the rope buckle 2 needs to be replaced, it is only necessary to move the telescopic rod 9 so that the limiting plate 10 retracts to no more than the edge of the displacement rod 8, and then the rope buckle 2 and the displacement rod 8 can be removed from the housing 1.
[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
