Detailed Embodiments
[0018] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in combination with embodiments and drawings. This embodiment is only used to explain the present utility model and does not constitute a limitation on the protection scope of the present utility model.
[0019] Please refer to Figures 1-4, this application provides a control component for a curtain, which includes an operating rod 1, a bead chain 2, and a control base 3. The control base is connected to the front end of the operating rod. On both sides inside the control base, there are chain channels for the bead chain to pass through. A part of the bead chain is exposed outside the control base and forms a sleeve opening 4, which is used to connect to the control head. Another part of the bead chain is connected to a sprocket 5 inside the operating rod. The sprocket is rotatably connected to a sprocket seat 6. Inside the operating rod 1, there is an elastic member 7 connected to the sprocket seat. Under the elastic force of the elastic member, all parts of the bead chain other than the part connected to the control head can be hidden inside the control base and the operating rod, avoiding the exposure of the bead chain when not in use. The elastic member is preferably a tension spring. Between the chain channels on both sides of the control base 3, there is a reversing seat. On both sides of the reversing seat, there are elastic claws 8 respectively. The reversing seat is slidably connected to the control base 3 and can slide to both sides. On the outside of the control base, there is a reversing operation part for controlling the sliding direction of the reversing seat.
[0020] The user operates the reversing seat to move to the right through the reversing operation part. The reversing seat has a chute. Correspondingly, inside the control base, there is a slide rail that cooperates with the chute. The elastic claw on the right side of the reversing seat catches on the bead chain on the right side, so that the bead chain can only move along the direction of the claw. At this time, the moving direction of the bead chain is set to make the control head rotate forward and slowly open the curtain; conversely, the user operates the reversing seat to move to the left through the reversing operation part. The elastic claw on the left side of the reversing seat catches on the bead chain on the left side, so that the bead chain can only move along the direction of the claw. At this time, the moving direction of the bead chain is set to make the control head rotate in reverse and slowly close the curtain.
[0021] The reversing seat includes a bottom shell 9, two elastic claws 8, an upper shell 10, and a spring. The two elastic claws are respectively rotatably connected to the bottom shell 9. The spring is arranged between the two elastic claws. The upper shell is connected to the bottom shell. With this structure, when the spring loses its elastic force, the spring can be replaced by disassembling the upper shell.
[0022] On the reversing seat, there are several first positioning parts 11. The several first positioning parts are distributed along the sliding direction of the reversing seat. The control base 3 has a second positioning part that cooperates with the first positioning part for positioning. The first positioning part is specifically a positioning groove, and the second positioning part is specifically a positioning convex part. After the positioning convex part is stuck into the positioning groove, the displacement of the reversing seat can be avoided. Only the force applied by the user when operating the reversing operation part can make the second positioning part enter different first positioning parts to achieve the positioning of the reversing seat.
[0023] The reversing operation part is a rotating seat 12. The rotating seat is rotatably connected to the control base 3. The rotating seat has a reversing lever 121. The reversing seat has a connection port for the reversing lever to extend into. When the user operates the rotating seat to rotate, the lever swings along with the rotation direction, thereby controlling the left and right movement of the reversing seat.
[0024] The control base 3 is internally provided with a limiting part 13 for restricting the swinging amplitude of the reversing lever, which plays a role in limiting and positioning, and avoids the elastic claws on the reversing base from jamming the bead chain due to excessive swinging of the lever.
[0025] Please refer to the attached Figure 5 , a reset base 14 is provided inside the control base 3. The reset base is in a downward pressed state and can move up and down relative to the control base. An elastic reset member 15 is provided between the bottom of the reset base and the control base. Reset portions 16 extending towards both sides of the reversing base are provided on both sides of the reset base. The top of the reset base is exposed outside the control base 3. When the user releases the operating lever, under the action of the tension spring, the control base will closely adhere to the head. At this time, the head presses the reset base, so that the reset portions on both sides of the reset base push the reversing base to the middle position, making the control assembly in the neutral state.
[0026] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed by the present invention should be included in the protection scope recorded in the claims.
