Problems solved by technology
The existing frame structure is mainly a square frame, which is mainly composed of four frame bars that are vertically connected to each other and fixed by fasteners, but the existing fasteners are mainly connecting plates, screws or bolts; these Once the conventional fasteners fix the frame bars, it is difficult to adjust the frame, especially for a square frame composed of four frame bars perpendicular to each other, after using the existing conventional fasteners, it is basically impossible to adjust the frame bars After using for a period of time, this kind of square frame tends to be stressed and loose, which affects the use effect of the square frame, especially the use of some decorative frames, door and window frames, etc. brings safety hazards

A fastening structure for splicing square frames, which includes a square frame composed of four adjacent frame sides perpendicular to each other, and the side plane of at least one frame side of the two adjacent mutually perpendicular frame sides A connection block is fixedly connected to the top, and the connection block is provided with a first flange perpendicular to the side plane of the frame, and the first flange is provided with a first screw hole; the first flange of the connection block passes through the first The screw holes are connected with fasteners, the fasteners are L-shaped, and the two sides of the L-shaped fasteners are respectively close to the two sides of the two mutually perpendicular frame sides, and the L-shaped ends of the fasteners The second convex edge corresponding to the first convex edge is provided on the part, and the second screw hole corresponding to the first screw hole is provided on the second convex edge, and the gap between the first convex edge and the second convex edge is There is a spacing for fastening; it has the characteristics of simple structure, convenient use and installation, the ability to adjust the distance between the frame bars to fasten each other, and ensure the firmness of the frame structure.
Description
technical field [0001] The invention relates to a spliced fastening structure of square frames, belonging to the technical field of frame structure fastening. Background technique [0002] The existing frames are basically made of frame strips connected by fasteners. The frame strips include plastic frame strips, aluminum alloy frame strips, etc., which are basically used in products such as window frames, door frames, and decorative frames. superior. The existing frame structure is mainly a square frame, which is mainly composed of four frame bars that are vertically connected to each other and fixed by fasteners, but the existing fasteners are mainly connecting plates, screws or bolts; these Once the conventional fasteners fix the frame bars, it is difficult to adjust the frame, especially for a square frame composed of four frame bars perpendicular to each other, after using the existing conventional fasteners, it is basically impossible to adjust the frame bars After...
