Splicing I-shaped tube and pull grid door and window sash splicing grid bar manufactured by same

Abstract

The invention discloses a splicing I-shaped tube and a pull grid door and window sash splicing grid bar manufactured by the same and relates to pull grid door and window. The splicing I-shaped tube is provided with a connection component and at least one side splicing component, wherein the connection component is provided with a longitudinal through cavity in the longitudinal direction and a longitudinal splicing structure with a longitudinal splicing groove or / and a longitudinal splicing bar along the longitudinal side end part; the side splicing component is provided with a longitudinal splicing structure with a longitudinal splicing bar which is matched with the connection component and / or a longitudinal splicing groove in the longitudinal direction; the connection component and the side splicing component are mutually spliced at the end parts by the respective longitudinal splicing structures and are spliced by longitudinally expanding and intersecting; the cross section of the splicing I-shaped tube is I-shaped; the axle wire of the front and rear direction of the cross section of the splicing I-shaped tube penetrates through at least four wall layers. The splicing grid bar is provided with the splicing I-shaped tube which is provided with one connection component and the at least one side splicing component. The precision is high, the structure is steady, the deformation is not easily caused, and the anti-impacting and bending performance and the torsional strength are high.

Description

technical field [0001] The invention relates to a sash door and window, in particular to an inlaid I-shaped pipe and an inlaid grid bar of the sash of a sash made of the same. Background technique [0002] Due to its unique structure, the sliding door and window sashes can be ventilated without affecting the lighting, and can play the role of protection, anti-intrusion and decoration, and it is also convenient for fire protection, so it is widely used. [0003] Existing sash doors and windows are generally composed of the main part, the grid bar, and a connector, a pivot, a sliding shaft, a puller and a frame. As the main component, the grid pole has a core function. There are three basic technical conditions commonly used in the industry: first, the pivot and sliding shafts are placed in the grid bar movably, and the shaft heads at both ends of the pivot and sliding shafts are not exposed; The shaft holes are respectively connected with the pivot shaft and the sliding sha...

AI Technical Summary

Problems solved by technology

[0005] 1. During the welding (argon arc welding) process of stainless steel welded rectangular tubes and the bars made of them, a large amount of welding fumes and ozone will be produced, as well as ultraviolet radiation 5 to 30 times higher than that of ordinary welding, which will cause great harm to the human body ;

[0006] 2. The welding parts need to be ground and polished, and a large amount of dust will be generated, which will cause great pollution to the environment;

[0007] 3. The production process is troublesome and the production cost is high;

[0008] 4. The finished grid pole has low precision, easy deformation, loose structure, poor impact bending and torsional strength, not firm, loud noise during use, and not smooth enough to move

After the pivot and sliding shaft are connected in series, they cannot be normally placed in the longitudinal cavity of the grid rod, and if riveted, the rivet head will be exposed outside, which will affect the appearance of the grid door and window sash
