Abstract
The utility model discloses a window opener and a locking device, and relates to the technical field of window openers, in order to solve the problem that a chain of an existing window opener is prone to disengagement, the locking device comprises a control mechanism, the control mechanism is used for controlling the movement of the chain, a locking piece is used for locking the chain, and the locking piece is rotationally connected with the control mechanism through a pin shaft. In the moving process of the chain, the acting force of the torsional spring is used for enabling the locking piece to be in lap joint with the top of the chain, the chain supports the locking piece, when the chain moves to the last chain link, the acting force of the torsional spring is larger than the supporting force of the chain, the locking piece is driven to rotate, and the locking piece is clamped into the last chain link. Through cooperation of the locking piece and the chain, locking and releasing of the chain are smoothly completed, and the chain is prevented from being completely disengaged from the window opener.
