Window screen combined double-inward-opening casement window structure

Abstract

A window screen combined double-inward-opening casement window structure is characterized in that the upper end and the lower end of a sash frame are rotationally connected with a window outer frame through first hinges respectively, a screen sash comprises a screen outer frame and a screen window frame hinged to the inner side of the screen window frame through a rotating axis, the inner side of the screen window frame is connected with a screen, and the upper end and the lower end of the screen window frame are rotationally connected with the window outer frame through second hinges respectively; a water collecting groove is formed in the upper portion of the window frame outer side sectional material, a drainage notch is correspondingly formed in the water collecting groove, and a drainage piece downwards penetrates through the window frame outer side sectional material. The mode of upper and lower hinges is adopted, axis opening is reinforced, the screen window cannot be detached, meanwhile, the opening angle is increased and can reach 75-86 degrees, and the whole screen outer frame is formed to serve as a screen auxiliary frame; the stability is improved; the drainage performance is improved through the drainage piece, a set of independent drainage and drainage lines from top to bottom are additionally arranged on the whole window, drainage is conducted to the outdoor side at the lowest transverse material in a unified mode, rainwater cannot flow backwards in windy weather, meanwhile, normal drainage cannot be affected, and the water outlet requirement is met.

Description

Technical field [0001] The present invention relates to the field of screen dual-in-line structures, and more particularly, more particularly to a window screen combination double opening structure. Background technique [0002] On the market, the glass fan opens on the double-open window, the glass fan is turned on by 90 degrees, but the inner open window can open as long as 30-45 degrees, and cannot be fully opened; and the yarn frame on the existing market is only vertical On the side, there is a difference in stability of the entire structure, there is different levels of security hazards; the drainage structure of the double-opened window is simple, the drainage method is the mandatory row, the opening position is too obvious, bringing a cumbersome processing operation and destroying the surface of the profile Absorbing the appearance of the frame, and the efficiency of drainage is relatively low, easy to fill the rain, open the space, the air space and cavity below, have a ...

AI Technical Summary

Problems solved by technology

[0002] For double inward opening windows on the market, the opening of the glass sash is based on 90-degree opening or 180-degree opening, but the opening angle of the inward-opening screen window is only 30-45 degrees, and cannot be fully opened; and the existing gauze frame on the market is only vertical There are edges, resulting in poor stability of the entire structure, and there are different degrees of safety hazards; the design of the drainage structure for double-opening windows is simple, and the drainage methods are all open rows, and the opening position is too obvious, which brings cumbersome processing operations and damages the surface of the profile. Affects the appearance of the outer frame, and the drainage efficiency is relatively low, it is easy to be poured by rainwater, and there is a large space and cavity under the opening position, which has a certain impact on the appearance and practicality
