Low-energy-consumption aluminum alloy out-opening window

Abstract

According to the low-energy-consumption aluminum alloy out-opening window, a sash rubber strip and an auxiliary frame upper heat insulation strip which are in lap joint with each other are arranged in an opening and closing cavity, cold (hot) air convection conduction is blocked, the temperature in the opening and closing cavity is reduced in summer, and the temperature in the opening and closing cavity is increased in winter. The sash rubber strip is provided with the inclined face, so that the lower side face of the sash rubber strip gradually gets close to the auxiliary frame upper heat insulation strip from the left side to the right side, and the auxiliary frame upper heat insulation strip is provided with the inclined face, so that the upper side face of the auxiliary frame upper heat insulation strip gradually gets close to the sash rubber strip from the left side to the right side. Outdoor air flow can be effectively prevented from transversely penetrating through the opening and closing cavity, the transverse air flow of the opening and closing cavity can be better blocked to reduce indoor and outdoor convection of air by combining the effect of the sash rubber strip sealing protrusion, and the sash rubber strip sealing protrusion can better adapt to an arc-shaped outward-opening rail of a sash. Besides, the right auxiliary frame section bar is additionally arranged, and the hardware notch is formed in the right auxiliary frame section bar, so that the lock seat is rotated to the indoor side, the length of the handle shifting fork is reduced, the opening and closing control performance is better improved, and the hardware stress requirement is met.

Description

technical field [0001] The invention relates to an aluminum alloy window, in particular to an aluminum alloy window opening outwards. Background technique [0002] With the continuous improvement of building energy-saving requirements, the use of aluminum alloy energy-saving doors and windows has increased rapidly in recent years, especially with the continuous emergence of passive houses, the demand for low-energy aluminum alloy windows that open outwards is increasing. Aluminum alloy has beautiful appearance, high strength and long service life, but its heat transfer coefficient is relatively high. It is relatively difficult to reduce the heat transfer coefficient K value of aluminum alloy window with broken bridge insulation. Since there must be an opening and closing cavity between the main part of the sash and the main part of the window frame of the aluminum alloy window to facilitate the opening and closing of the window, the sealing and heat insulation of the opening...

AI Technical Summary

Problems solved by technology

The disadvantage is that the length of the handle fork is greatly increased, which changes the stress structure of the hardware, not only the opening and closing is not smooth through the handle control, but also seriously affects the service life of the hardware
