Description

Technical Field

[0001] The utility model relates to the field of handle locks for extremely narrow casement windows, and more specifically, to a handle and lock box transmission structure for extremely narrow casement windows. Background Art

[0002] In the field of modern architecture, the most widely used aluminum alloy windows are sliding windows and casement windows. Casement windows have gradually replaced sliding windows and become the mainstream in high-end buildings due to their excellent sealing performance. Among them, casement windows are composed of profiles wrapped with glass. A connecting rod device is installed at the outer edge of the profile. The connecting rod device is provided with a locking point structure that matches the door and window. The window sash is equipped with a handle and a transmission box is provided between the connecting rod device. The transmission box is usually mounted in the profile through structural size matching. The transmission box is provided with a switch rack and a transmission gear that mesh with each other. The transmission gear drives the switch rack to move, converting the circular motion into a linear motion of translation. The switch rack is generally installed in the middle of the transmission rod. Through the forward or reverse rotation of the transmission gear, the switch rack is driven to reciprocate in the linear direction, thereby driving the front and rear displacement of the transmission rod.

[0003] Since the handle shell is equipped with numerous parts, it needs to be designed with a larger volume. During installation, it will protrude from the corners of the sash frame and even overlap the pressure line of the pressure strip, which not only affects the appearance but also hinders the installation of doors and windows.
