Description

Door and window cantilever locking mechanism

Technical Field

The utility model relates to a door and window structure specifically is a door and window cantilever locking mechanism.

Background

The hardware fittings of the inner-falling door and window mainly comprise three parts, namely an upper cantilever, a lower cantilever and a transmission mechanism. The three states of the translational inverted window are as follows:

1) locking state: the upper cantilever and the lower cantilever are closed, and the lock point of the transmission mechanism is matched with the lock seat to lock the fan on the frame;

2) a translation state: the upper cantilever and the lower cantilever are both opened, at the moment, the fan is separated from the frame, and the fan can slide on the track of the frame;

3) inverted (suspended) state: the cantilever on the upper part is opened, the cantilever on the lower part is closed, at the moment, the fan and the frame form a certain included angle, the upper part is ventilated, and the fan cannot slide.

The three states of the inward-falling door and window do not allow the lower cantilever to be opened when the inward-falling door and window are turned inwards or locked. Referring to fig. 1, the inward-falling state is mainly realized by the cooperation of the locking point 21 on the sash 10 and the locking seat 40 on the frame, that is, the lower part of the sash 10 is locked, and the upper part is opened, but the locking is only the inward-falling locking, because the lower frame 30 cannot be simultaneously provided with the inward-falling locking point and the transmission locking point, when the sash 10 is in the fully-closed state, there is no locking point for locking between the lower frame 30 and the sash 10, and the safety and the sealing performance are poor. The lower part of the existing translation window is open and is provided with a transmission part, a notch of a hardware is not installed, the lock seat cannot be installed to increase the inward falling function, and structural transformation and use of doors and windows are limited.
