Energy-saving glass window with sash capable of rotating by 90 degrees

Abstract

The invention discloses an energy-saving glass window with a sash capable of rotating by 90 degrees. The energy-saving glass window is characterized in that the included angle of a left frame right vertical plate and a left frame front vertical plate of a left frame of a window frame is greater than 90 degrees, the included angle of a right frame left vertical plate and a right frame front vertical plate of a right frame is smaller than 90 degrees, and sealing parts are installed on the right side of the left frame and the left side of the right frame; sealing parts are installed on the left side of a left rabbet of the sash and the right side of a right rabbet of the sash; the sum of the included angle of a left rabbet left vertical plate and a left rabbet front vertical plate and the included angle of the left frame right vertical plate and the left frame front vertical plate is 180 degrees; the sum of a right rabbet right vertical plate and a right rabbet front vertical plate and the included angle of a right frame left vertical plate and the right frame front vertical plate is 180 degrees; the sash is installed in the window frame by an upper groove-shaped jaw, an upper rotating shaft, an upper shaft seat, a lower groove-shaped jaw, a lower rotating shaft, a thrust bearing and a bearing box, and the axis of the upper rotating shaft and the axis of the lower rotating shaft coincide with the vertical center line of the sash. The sash can be perpendicular to the window frame when being opened so that the ventilation area can be maximized; only half of the sash is located outdoors, so that the safety performance is good.

Description

technical field [0001] The invention relates to a glass window, in particular to an energy-saving glass window whose sash can be rotated by 90°; The distance from the centerline of the vertical direction is greater than or equal to zero. Background technique [0002] Existing glass windows have several disadvantages: the one is that the ventilation effect of various glass windows is not good; the ventilation area of ​​the sliding window is less than 50% of the window area, if dead glass is installed, its ventilation area accounts for 50% of the window area. The ratio is lower; all the sashes of the casement windows can be opened, but the rotation angle of the sashes is not large, generally only 60°, resulting in poor ventilation. The 2nd, because there is relative movement between the sash and the window frame of the sliding window, the two are sealed by wool strips, and the sealing effect is very poor. The 3rd, the sash of casement window hangs outside the window frame wh...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the disadvantages of poor ventilation effect and low safety performance in the existing casement glass windows, and provide an energy-saving glass window whose sash can be rotated 90°, and the glass window realizes the largest ventilation area The ventilation effect can be optimized, and its safety performance has also been greatly improved.
