a sliding window

Abstract

The invention discloses a push-pull window, which comprises a rear-assembled center sill cover plate, a center sill and a sash profile; the upper, lower, and window frames of the center stile are all provided with auxiliary heat-insulating profiles and a heat-insulating decorative cover plate used in conjunction. The use of two profiles completely separates the outdoor profiles and indoor profiles of the sliding window, thereby greatly improving the heat insulation effect of the entire window, which is better in energy saving and cost-effective than traditional aluminum alloy sliding windows with broken bridges The key point of the present invention is: auxiliary heat insulation material, heat insulation decorative cover plate, rear assembly mid-stand cover plate, elastic heat insulation movable cover plate, and heat insulation profiles for fixed pulleys are provided. The structural design of the window is better, so that the heat insulation effect of the whole window of the sliding window of the present invention is greatly improved, and the cost performance is high. load-bearing strength and wind pressure strength.

Description

technical field [0001] The invention relates to the technical field of sliding windows, in particular to a sliding window. Background technique [0002] There are two types of sliding windows: single-leaf sliding windows and double-leaf sliding windows. The upper part of the sliding window needs to slide in the groove of the upper slideway, and the lower part of the sliding window needs to be equipped with pulleys and move along the track; when the traditional sliding window is installed, it needs to be installed at the upper end. The lower part of the sash profile crosses the slide rail and then falls down, resulting in a large gap between the sash profile and the upper slide groove, which seriously affects the air-tightness of the sliding window and increases the risk of on-site installation. [0003] The sliding window of the present invention adopts the structure design of the rear-assembled cover plate. When the window sash profile is installed, the lower part of the wi...

AI Technical Summary

Problems solved by technology

[0002] Sliding windows are divided into two types: single sliding window and double sliding window. The upper part of the sliding window needs to slide in the groove of the upper slideway, and the lower part of the sliding window needs to be equipped with pulleys and move along the track; The lower part of the sash profile crosses the lower rail and then falls, resulting in a large gap between the sash profile and the groove of the upper slideway, which seriously affects the airtightness of the sliding window and increases the risk of on-site installation.
