A kind of energy-saving thermal insulation door and window

Abstract

The application relates to an energy-saving and heat-retaining door and window, which includes a window frame and two sashes, one of which is the first sash and the other is the second sash, and the frame of the first sash is provided with a receiving groove and a sealing strip roller. The sealing strip roller is rotatably connected with the first window sash, the sealing strip roller can be rotatably stored in the accommodation groove or rotated out of the accommodation groove, and when the sealing strip roller rotates out of the accommodation groove, the sealing The peripheral surface of the strip roller abuts against the surface of the frame of the second sash facing the first sash. This application uses a rotatable sealing strip roller to rotate out of the accommodation groove and fill the gap between the two window sashes according to actual needs, so as to selectively perform sealing, thereby reducing structural damage caused by frequent friction, so as to ensure the sealing effect of lasting stability.

Description

technical field [0001] The application relates to the field of doors and windows, in particular to an energy-saving and thermal insulation door and window. Background technique [0002] Energy-saving doors and windows are a kind of doors and windows to increase the lighting and ventilation area or to express the character characteristics of modern buildings. Energy-saving doors and windows will improve the optical performance, thermal performance and sealing of materials, and improve the structure of doors and windows to achieve the expected effect. [0003] Sliding windows are a kind of doors and windows, including a window frame and two sashes. The sash is equipped with a pulley. Through the cooperation between the pulley and the guide groove, the horizontal sliding of the sash is realized. The advantage of this kind of window is that the window does not occupy the The extra space, the structure is also relatively simple. [0004] But in order to slide without interferin...

AI Technical Summary

Problems solved by technology

[0004] However, in order to slide without interfering with each other, there must be a certain gap between the two sashes, and the heat in the room is easily transmitted through the gap, resulting in a drop in the indoor temperature.

[0005] Therefore, flexible strips, such as wool strips or rubber strips, are often glued on the frame of the window sash to fill the gap. However, during long-term use, the flexible strip often rubs against the frame of the adjacent window sash, and the structure is easily damaged. That is, the thickness is reduced, and it is difficult to fill the gap, resulting in a reduced thermal insulation effect
