Sliding type unfolding type double-door-frame structure based on alloy doors and windows

Abstract

The invention discloses a sliding type unfolding type double-door-frame structure based on alloy doors and windows, and relates to the technical field of alloy doors and windows. The problems that a door frame structure used at present is mainly of a transverse pulling type or an outward turning type and does not have a bidirectional unfolding and closing function, and the door and window opening mode is inconvenient to select according to use requirements are solved. The sliding type unfolding type double-door-frame structure based on the alloy doors and windows comprises a frame; the inner ends of the upper side and the lower side of the frame are each provided with two sliding grooves; and an outer window frame and an inner window frame are arranged in the frame in a sliding mode, and sliding strip structures are integrally arranged at the bottoms of the outer window frame and the inner window frame. The sliding grooves and lifting sliding strips are arranged, the transverse overlapping type sliding opening and closing function is provided for the door frame, a short lead screw is rotated to drive a middle sliding block to move forwards through thread transmission, furthermore, short connecting rods form a sliding block mechanism to lift the lifting sliding strips to limit and fix the outer window frame and the inner window frame, so that the outer window frame and the inner window frame are in sliding connection with the sliding grooves, and assembly and disassembly are convenient.

Description

technical field [0001] The invention relates to the technical field of alloy doors and windows, in particular to a sliding and unfolding double door frame structure based on alloy doors and windows. Background technique [0002] Doors and windows, in architecture, refer to openings built on walls or roofs to allow light or air to enter the room. As early as the Sui Dynasty in China, windows that could be opened and closed automatically appeared in the Guanwen Hall in Ziwei City, Luoyang Imperial Palace. Glass is installed through the door frame structure of the window for protection. [0003] After retrieval, for example, the patent No. CN208416310U discloses a reversible two-way closed door and window, including an outer frame, an inner frame for fixing the door and window, a connecting shaft for connecting and installing the inner frame and the outer frame, and a mounting groove installed on the inner side of the outer frame. in the sealing device. The sealing device inc...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a sliding-type unfolding double door frame structure based on alloy doors and windows, so as to solve the problem that the currently used door frame structure proposed in the above background technology is mainly a horizontal pull type or an eversion type, which does not have a two-way opening and closing function. It is inconvenient to choose the way to open doors and windows according to the needs of use, which is not conducive to the problem of flexible use at home
