Locking structure for sliding window

Abstract

The invention relates to a locking structure for a sliding window. The locking structure comprises a frame, wherein the frame is internally provided with a movable sash frame, the movable sash frame comprises a vertical sash frame, a locking device is arranged in the vertical sash frame, and a lock body is arranged at the position, corresponding to the locking device, of the frame; the locking device comprises a first linkage piece and a second linkage piece, wherein the bottom side of the first linkage piece is connected to the bottom surface of the vertical sash frame through a spring, the top side of the second linkage piece is connected to the top surface of the vertical sash frame through a spring, a first through hole is formed in the position, corresponding to the lock body, of thefirst linkage piece, a second through hole is formed in the position, corresponding to the lock body, of the second linkage piece, the lock body sequentially penetrates through the first through hole,and the second through hole is connected with the first linkage piece and the second linkage piece through a buckle. The locking structure can effectively lock the sliding window, and is stable in structure, good in anti-theft performance, not easy to pry, and practical.

Description

technical field [0001] The invention relates to a locking structure, in particular to a locking structure for sliding windows. Background technique [0002] Doors and windows can be divided into sliding windows, casement windows, sliding windows, etc. In ordinary people's lives, sliding windows are more common. Traditional sliding windows use single-point locks, and the deadbolt and lock body are hooked up and down to lock the sliding windows. Locking the window can effectively limit the relative translational movement of the sliding window, but it does not limit the movement of the sliding window in the vertical direction, because the form installation of the sliding window is usually to connect the fan frame and the guide rail on the window frame vertically. The vertical direction fits, so the sash can move a certain distance vertically in the window frame, which leads to poor anti-theft performance of the sliding window. You can directly lift the sash to detach the sash f...

Problems solved by technology

[0003] The invention provides that the technical problem to be solved is that the locking structure of the sliding window is not tight enough, and in the locked state, the fan frame can also move in the vertical direction and be detached from the window frame, so the anti-theft performance is poor
