[0059] The steps for using the window switch lock linkage mechanism provided in this embodiment are as follows:

[0060] The window closing and locking working actions of the mechanism are as follows: during the window closing process, the sliding member at the actuator end of the window opener first slides along the oblique sliding groove 22 to close the window. When it is close to the window closing position, the sliding member enters the groove portion of the rotating groove 9, which will apply a clockwise rotating external force to the rotating groove 9 and continue to push the window sash to close the window. When the window sash is about to be closed, the unlocking piece of the rotating groove unlocking piece 11 hits the side of the window frame and is pressed down, that is, the rotating groove unlocking piece 11 overcomes the elastic torsion force of the second torsion spring 23 and rotates clockwise, withdrawing the unlocking piece convex beak 113 that originally pressed against the upper end of the rotating groove 9, unlocking the side of the end of the rotating groove 9, and the sliding member fluctuates the rotating groove 9 of the rotating groove assembly, overcoming the torsion force of the first torsion spring 20 The elastic torsion force applied by the force arm to the side surface of the lower end of the fan-shaped tooth portion drives the rotary groove tooth piece 10 to rotate with the rotary groove shaft column 84 as the selection axis (clockwise in the embodiment drawing), and the tooth portion of the rotary groove assembly drives the rack 12 meshing with its tooth portion to slide downward, and the rack 12 drives the connecting rod 14 to press downward, and then drives the rocker arm 13 to rotate with the rocker arm bracket pin 17 as the rotation axis (counterclockwise in the embodiment drawing), and the rocker arm push-pull convex head 132 at the convex head end of the rocker arm 13 pulls the bottom groove connecting rod 19 to slide (to the left in the embodiment drawing), drives the connecting rod locking point pin sleeve 24 to approach the locking point block on the bottom edge of the window frame, and makes the connecting rod locking point pin sleeve 24 buckle with the locking point block to complete the window sash locking action.

[0061] The unlocking and window opening working actions are as follows: during the window opening process, the sliding push piece at the actuator end of the window opener first moves the rotating groove 9 of the rotating groove assembly in the window opening direction, and with the assistance of the elastic torque applied by the torque arm of the first torsion spring 20 originally in a compressed state to the lower end side of its fan-shaped tooth portion, the rotating groove tooth piece 10 is driven to rotate with the rotating groove shaft column 84 as the rotation axis (counterclockwise in the embodiment drawings), and the tooth portion of the rotating groove assembly drives the rack 12 meshing with its tooth portion to slide upward, and the rack 12 drives the connecting rod 14 to lift up, and then drives the rocker arm 13 to rotate with the rocker arm bracket pin 17 as the rotation axis (clockwise in the embodiment drawings), and the rocker arm push-pull convex head 132 at the convex head end of the rocker arm 13 is connected to the bottom groove through The rocker arm push-pull hole 191 at one end of the connecting rod 19 is connected by a gap nesting connection, and the bottom groove connecting rod 19 with a gap nesting in the bottom groove of the side edge 2 of the window sash is pulled to slide (to the right in the attached figure of the embodiment), and the connecting rod locking point pin sleeve 24 is gradually disengaged from the locking point block on the bottom edge of the window frame. When the groove portion of the rotating groove 9 is rotated to be aligned with the oblique sliding groove 22, the window sash unlocking action is completed; at the same time, the unlocking piece 11 of the rotating groove presses the tail end 114 and gradually separates from the window frame, and rotates under the elastic torsion of the second torsion spring 23. The convex beak 113 of the unlocking piece will rotate into place after the groove portion of the rotating groove 9 is rotated to be aligned with the oblique sliding groove 22, and it will press against the side surface of the upper end of the rotating groove 9 to lock the side edge of the end of the rotating groove 9.

[0062] It should be additionally explained that if the sliding member at the actuator end of the window opener continues to push the window sash along the groove portion of the rotating groove 9 and enters the groove portion of the oblique sliding groove 22, the window sash continues to open to a larger angle range.

[0063] Through the above structure, a window switch lock linkage mechanism is provided, which consists of a connected bracket 8 and a rotating groove 9 component installed thereon, a rotating groove unlocking piece 11 and an unlocking piece pin 18, a rack 12 and a rack pin 16, a rocker arm 13 and a rocker arm bracket pin 17, a connecting rod 14 and a rack connecting rod pin 15, a first torsion spring 20 and a second torsion spring 23. The structure is simple and the flat design is designed. It is installed in a wrap-around manner on a corner of the window sash and is used in conjunction with a concealed window opener. When the window is about to be closed, the rotating groove unlocking piece 11 is pressed down to rotate the rotating groove 9 component, and then the latter pushes the rack 12 to drive the connecting rod 14 to rotate the rocker arm 13 and then pull the bottom groove connecting rod 19 component to lock the window sash, that is, to achieve window closing and locking. The rotating groove 9 component reverses to complete the unlocking and window opening actions. Compared with similar products of concealed electric windows on the market that use a window opener plus an electric lock box, the electric lock box is eliminated, the mechanism is simplified, and the manufacturing and installation links are saved.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
