A locking device for window blind between two panes of glass is disclosed. The window blind is arranged between tow panes of glass through the attraction of the inside magnet and the outside magnet to transmit power to control the operation of the window blind. The locking device may achieve the effects of controlling smoothly and stopping firmly. The locking device may comprise a control shaft and a track. The control shaft includes a locking body, a switch, a hook, a spring, a bearing, and a magnet. The control shaft may be connected with the track through a hook position. The window blind is controlled by attraction of the inside magnet and the outside magnet to achieve the effects of control of raising and lowering the window blind between two panes of glass and light modulation. The locking device is controlled the engagement and disengagement between the hook and the track by the switch to ensure the window blind stopping at any position and without sliding down. |

1. A locking device for window blind between two panes of glass, characterized by smoothly releasing and firmly stopped through the locking device, the locking device comprising a control shaft and a track, wherein:
the control shaft includes a locking body, a switch, a hook, a spring, a bearing, and a magnet, the control shaft is connected with the track through a hook position; when the control shaft is pressed down and the window blind is raised, the hand is naturally touching the switch and then the hook is disengaged from a plurality of teeth of the track so that the window blind is raised smoothly; when the control shaft is released, the hook is attracted to the track by the spring and the control shaft is locked to stop the window blind; when the control shaft is moved downwardly, the track is supplying a counter acting force to the hook by the theorem of the direction of force to push the hook to move to the other side and stride over the teeth of the track and then to control the control shaft to be lowered at will to raise the window blind; when the control shaft is stopped to move, the hook is engaged and locked at the teeth of the track through the force of the spring; at this time, the track forces to the hook downwardly and is perpendicular to the moving direction of the hook so that the hook is not able to be pushed and the control shaft is firmly locked at the track to achieve the effect of locking the window blind at any position; and when the window blind is lowered, the hook is pushed inwardly by the switch which is pressed down and the hook is disengaged from the teeth of the track to achieve the effect of lowering the window blind at will. |
