A high-tightness sliding window

Abstract

The embodiment of the invention discloses a push-pull window high in sealing property. The window includes a window frame and a window sash which can move along the window frame; the lower end of thewindow sash is provided with a wheel frame, a main pulley and an auxiliary pulley, and the main pulley and the auxiliary pulley are respectively installed at different heights of the wheel frame. Thewindow frame is provided with a main slide rail and an auxiliary slide rail which are cooperated with the main pulley and the auxiliary pulley respectively, and the main slide rail and the auxiliary slide rail correspond to the opening position and closed position of the window sash respectively and are different in height; therefore, at the opening position of the window sash, the main pulley makes contact with the main slide rail, the auxiliary pulley is separated from the auxiliary slide rail; at the closed position of the window sash, the auxiliary pulley makes contact with the auxiliary slide rail, the main pulley is separated from the main slide rail, and the wheel frame rotates a predetermined angle; the wheel frame is connected with the window sash through a screw rod. According tothe push-pull window, the screw rod drives the window sash to move towards the side face of the window frame, it is ensured that the window sash and the window frame stay close to each other in the closed state, the sealing property of the window sash and the window frame can be improved, the service life is long and the window is stable and reliable.

Description

technical field [0001] The invention relates to a sliding window, in particular to a high sealing sliding window. Background technique [0002] In order to improve the airtightness of sliding windows, the industry often hopes that the sash and the window frame of sliding windows will be close to each other after the sliding window is closed, so as to improve its airtightness. There are mainly two types of existing implementations. The first one is to install a lateral pressing device on the lock, and when the lock locks the sash, push the sash toward the outdoor direction of the window frame at the same time, causing the sash to produce a small displacement, thereby making the window sash move slightly with the sash. The window frame is tight. In this way, a lateral force will be generated on the pulley when the window sash moves, so that the whole window sash is always under the action of torsion, which may easily cause deformation of the window sash or damage to the pulle...

AI Technical Summary

Problems solved by technology

This method exerts lateral force on the window sash through the slide rail. Long-term operation will lead to wear of the slide rail, and the wear of the slide rail will cause a new gap between the window sash and the window frame, which will affect the sealing effect.
