In the LED display industry, the magnetic attraction design method of the display module is to install the magnet on the bottom shell or box, and then stick the display module on the box.

[0003] However, in the prior art, in the current assembly process of LED display screen brackets, the traditional assembly is mostly in two ways. The first case is that multiple LED display screen unit boards are first integrated into a frame box, and then multiple frame boxes are spliced, which is extremely costly, and during assembly, the shape of the connecting edge may not be accurately matched during docking, resulting in docking difficulties, making the overall assembly of the frame box more complicated, and it is necessary to match the customized structure and edge wrapping to complete the production and installation. Although the first method has better firmness, flatness and stability, it is more expensive, the process is cumbersome, and the efficiency is low. The second case is mostly self-processing, welding or the use of other standard frame products, but there is also the problem of low efficiency and non-universal product component standards. Different standards will waste energy and inefficiency during production, warehousing, assembly, and installation, which will increase production, warehousing and inventory costs.

The transverse keel 4 is located below the horizontal plane of the multiple groups of vertical C-shaped keels 6 and the upper and lower surfaces fit together, forming a uniformly distributed load-bearing network, so that the load can be evenly distributed on the entire structure, reducing local overload and extending service life.

[0043] The method of using the device and the working principle are as follows: first, during the assembly operation, the low-level aluminum alloy extruded profile 101, the middle-level aluminum alloy extruded profile 103 and the high-level aluminum alloy extruded profile 102 are formed into an integrated combination, and both ends of the formed several sections of the side frame connecting sections are cut to form beveled edges 108, thereby ensuring the strength and rigidity of the structure. The design of the beveled edges 108 is used to improve the butt-jointing degree of the edges during subsequent assembly, thereby reducing the risk of damage caused by external force impact and improving the assembly efficiency. Then, a group of bottom edges 111 are used to fasten the aluminum alloy extruded profile butt joint 10 and the mounting profile 110, thereby facilitating the installation of the low-level aluminum alloy extruded profile 101, the middle-level aluminum alloy extruded profile 103 and the high-level aluminum alloy extruded profile 102 respectively. The side frame 1 and the side frame 2 are assembled by butting the empty grooves of the aluminum alloy extruded profile 103 to form a plurality of side frame connecting sections, and during the above assembly, the mounting profile 110 is first aligned with the side frame connecting end, and the bottom edge 111 is used to form a preliminary positioning and support with the side frame structure, and then the self-tapping screws are passed through the screw holes on the mounting profile 110 to achieve the safe locking of the whole side frame assembly 1, and the special shape design of the isosceles trapezoidal connecting profile 112 further ensures the stable and precise alignment between the two sets of side frame connecting sections, so that the third horizontal protrusion 104 and the fourth horizontal protrusion 105 form a horizontal line with the first horizontal protrusion 113 and the second horizontal protrusion 114, and the fixing screws of the C-shaped keel are located on the first horizontal protrusion, the second horizontal protrusion, and the third horizontal protrusion. The groove between the flat protrusion and the fourth horizontal protrusion effectively avoids the influence of the burr extruded when the self-tapping screw is driven in and fixed on the flatness of the keel, so that during the assembly process, several sections of the side frame connecting sections and the isosceles trapezoidal connecting profile 112 can be accurately aligned and the connection stability is enhanced, which simplifies the assembly process and is also convenient for subsequent maintenance and adjustment. Among them, the arrangement of the bottom edge 111 and the aluminum alloy extruded profile docking piece 10 can be used to enhance the strength of the local area, or as a connection main line of the internal LED display circuit board, and the remaining hidden installation position of the electronic components that control the LED display circuit board, effectively improving the integration and practicality of the overall structure, and the one-piece molding of the slot plate 106 not only strengthens the center aluminum alloy extruded profile 1 03 is connected with the high-position aluminum alloy extruded profile 102, which is also convenient for the horizontal placement of the vertical C-shaped keel 6 and the horizontal keel 4. Then, the arc corner edge sealing piece 2 is set so that the side frame 1, the side frame 2 and the vertical side frame 3 have an extra 1 mm installation distance reserved for use on the left and right to ensure the consistency of the overall assembly. The first aluminum alloy extruded profile angle code 9 and the second aluminum alloy extruded profile angle code 8 are used to dock with the side frame 1, the side frame 2 and the vertical side frame 3 at both ends respectively, so that the setting of the first aluminum alloy extruded profile angle code 9 and the second aluminum alloy extruded profile angle code 8 can effectively disperse the external force applied to the peripheral side frame 1, the side frame 2 and the vertical side frame 3 through its special hollow shape, avoid local stress concentration, thereby improving the durability and deformation resistance of the entire structure.And it is convenient to assemble the whole by mortise and tenon or plug connection, which is effective for subsequent replacement and disassembly. After that, the edge sealing of the arc corner edge sealing piece 2 effectively prevents the invasion of external dust and moisture, and protects the internal components from environmental damage. Among them, the vertical side frame 3 is made into an integrated metal frame through one-piece molding technology or pre-assembled with a multi-segment structure that is the same as the side frame connecting section. When the multi-segment structure that is the same as the side frame connecting section is adopted, that is, the size of the vertical side frame 3 and the side frame connecting section is the same, it is convenient to only need one size standard in the production process, and then it can form unlimited connections through the middle quick assembly component 11, so as to quickly adapt to different installation scenarios, reducing the processing operation cost, and then the sheet metal connecting piece 5 is symmetrically installed at both ends of the horizontal keel 4, and all parts are connected by docking fixing holes using self- The tapping screw fixation enhances the support and stability of the middle part. The vertical C-shaped keel 4 and multiple groups of vertical C-shaped keels 6 are connected by threads through the embedded connection holes. The transverse keel 4 is located at the lower part of the horizontal plane of the multiple groups of vertical C-shaped keels 6 and forms an upper and lower surface fit. The vertical C-shaped keel 4 and the transverse keel 6 are set to significantly improve the transverse and longitudinal load-bearing capacity of the entire frame, which is suitable for carrying heavy or distributed loads. At the same time, the overall assembly structure adopts standardized interfaces and modular design. The length of the vertical side frame 3 can be adjusted according to actual needs, and the vertical C-shaped keel 4 can be added or the position of the transverse keel 6 can be adjusted to meet different installation requirements and space layouts. All screw holes, installation hole ends, docking fixing holes, etc. are fastened with self-tapping screws to ensure the tightness and stability of the overall structure.
