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

Disclosed is a fastening structure spliced by a square frame. The fastening structure comprises the square frame, four frame sides which are pairwise adjacent are respectively mutually and vertically connected to form the square frame, connecting blocks are fixedly connected with a side plane of at least one frame side of two adjacent and mutually vertical frame sides, first protruding sides which are vertical to side planes of the frame sides are disposed on the connecting blocks, and first screw holes are formed in the first protruding sides; the first protruding sides of the connecting blocks are connected with fastening pieces through the first screw holes, the fastening pieces are in an L shape, two sides of the L shapes of the fastening pieces are tightly attached to two side surfaces of two mutually vertical frame sides, second protruding sides which correspond to the first protruding sides are disposed at ends of the L shapes of the fastening pieces, second screw holes which correspond to the first screw holes are formed in the second protruding sides, and intervals used for fastening are reserved between the first protruding sides and the second protruding sides. The fastening structure spliced by the square frame has the advantages that the structure is simple, usage and mounting are convenient, mutually fastening distance between frame bars can be adjusted, and the using firmness of the frame structure is guaranteed.
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...
