Document Type and Number:
WIPO Patent Application WO/2018/177392
Kind Code:
A1
Abstract:
A frame forming structure for use with a frame and sash of an aluminum–wood combined door and window, the door and window at least comprising a door and window frame or a door and window sash and frame: the door and window frame or the door and window sash and frame is formed by connecting adjacent sectional frame bars (1) by means of an angle forming device (2) and a circular tenon rod (3) on adjacent connection end surfaces; connection end surfaces of two adjacent sectional frame bars (1) are manufactured to oppose an end plane of a normal sectional frame bar to assume a 0-60° cross section, respectively, and are mutually connected to form a perpendicular frame edge; the connection end surfaces of the two sectional frame bars (1) are processed to be provided thereon with a symmetrical U-shaped groove (4), which is used for positioning the angle forming device, and circular tenon rod hole (5), respectively; a circular tenon rod (6), which is used for positioning, is inserted into the circular tenon rod hole (5); after the adjacent sectional frame bars (1) are mutually coupled, a space (7) which is used for accommodating the assembly-type angle forming device (2) is formed at a coupling location, the assembly-type angle forming device (2) being formed by means of combining two halves of the angle forming device (21), wherein the two halves of the angle forming device (21) are each fixed in a corresponding U-shaped groove (4), which is used for positioning a sectional frame bar, by using a screw (22), and the two halves of the angle forming device (21) are mechanically tightened by means of a bevel gear pair mechanism, which is paired in a three-pronged engagement, to tightly fix and connect the two adjacent sectional frame bars (1). The present invention has the features of being capable of increasing connection strength at angle portions, increasing sealing performance after angle formation, improving the convenience of frame forming, increasing productivity, and the like.
