[0002] The door and window transmission lower lock cover drive structure is an important mechanical transmission device used to realize the locking and unlocking functions of doors and windows. The structure is mainly composed of a lower lock cover, a transmission device, and a series of gears and transmission parts. The lower lock cover is usually fixed on the frame material of the door and window, and is equipped with a drive member and a lock seat and other parts inside, which are used to cooperate with the lock member on the door and window leaf to realize the locking of the door and window. The transmission device is connected to the door and window leaf. By operating the transmission device, the drive member in the lower lock cover can be driven to extend and retract, thereby controlling the opening and closing of the door and window.
[0003] In the door and window transmission lower lock cover drive structure, gears and transmission components play a key role. The gears mesh with each other to convert the rotating circular motion into the translational linear motion, thereby driving the extension and retraction of the drive.
