If the matching is wrong, either the non-drawing curtains will fall down rapidly during operation and may cause accidents, or the non-drawing curtains will be rolled up and cannot be fixed in the half-open position. state
In addition, the current cordless curtain control device includes a return force mechanism and a spring-damping stop brake mechanism. When the elastic components inside the return force mechanism or the stop brake mechanism are mechanically fatigued, it may not be possible to keep the curtain fully open. or the curtain is fully closed
In addition, when the cordless curtain is lowered to the expected position, it will still be rolled back for a short distance, which causes inconvenience in use and confusion for users

The invention discloses a clutch type cord-free curtain control device and a locking and braking mechanism of the control device. The control device comprises a back-action mechanism and a locking and braking mechanism. The locking and braking mechanism comprises an outer shell with a meshing clamp disc, a transmission rod connecting piece with a shift lever, and a clutch rotor with a file squeezing pattern. Clamping teeth are arranged at one end of the clutch rotor, the axial distance from the shift lever to the meshing clamp disc is kept fixed. The file squeezing pattern is provided with a curtain dropping clutch point, a curtain rising clutch point and a curtain locking and clamping point, so that the clutch rotor dos axial movement relative to the transmission rod connecting piece, and the clamping teeth of the clutch rotor are meshed with or separated from the meshing clamp disc of the outer shell, wherein the curtain dropping clutch point allows a file squeezing rod to be positioned. Therefore, the locking height of the cord-free curtain control device can be precisely controlled, and the use safety can be improved.
Description
technical field [0001] The invention relates to a control device for a cordless curtain, in particular to a clutch type cordless curtain control device and its stop brake mechanism. Background technique [0002] In the early days, the rise and fall of the curtain was controlled by a pull-cord type curtain control device. A brake controller was installed on the side of the track above the curtain, and a bead chain (or pull rope) was suspended by the brake controller. By pulling the bead chain Rotate the way to open and close the up and down of the curtains. However, when the bead chain exists, it is said that there is a fatal accident of hanging the head of a child. Therefore, in the recent household product regulations, countries have gradually banned the use of drawstring curtains in buildings. . Therefore, the cordless curtain is a necessary product at present, but even if the structural design of the cordless curtain is various, the operation of the lift switch is not as...
