[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 3 As shown, the utility model provides a corner piece structure of an LED advertising light box, including a corner piece body 100 and a right-angle plug-in strip 200. A right-angle through groove 110 is formed inside the corner piece body 100, and the corner portion of the right-angle plug-in strip 200 is embedded in the right-angle through groove 110. Both ends of the right-angle plug-in strip 200 extend to the outside of the right-angle through groove 110 and are connected to a plate 300.

[0022] During implementation, since the right-angle plug-in strip 200 is in a right-angle shape, it is embedded in the right-angle through groove 110 of the corner piece body 100, and the connection with the corner piece body 100 is firm without the risk of falling off.

[0023] The corner piece body 100 in this embodiment is used not only to fix the right-angle plug strip 200, but also to abut two mutually perpendicular plates 300. Four corner piece bodies 100 and four plates 300 are connected in sequence to form a square frame structure of an advertising light box frame. In order to facilitate the fixing of the right-angle plug strip 200, a right-angle through groove 110 is formed inside the corner piece body 100 to facilitate the fixing of the right-angle plug strip 200.

[0024] like Figure 2 As shown, in order to facilitate the placement of the right-angle plug-in strip 200 in the right-angle groove 110, in one embodiment, the corner piece body 100 includes two corner panels 120, and the two corner panels 120 are both formed with a splicing bevel 121. The splicing bevels 121 of the two corner panels 120 are interconnected to form a right-angle structure, and the interiors of the two corner panels 120 are respectively formed with strip grooves 122 along two directions perpendicular to each other, and the two strip grooves 122 pass through one end of the splicing bevel 121 and are connected to form a right-angle groove 110.

[0025] Specifically, the two right-angle sides of the right-angle plug strip 200 are respectively inserted into the two strip-shaped through grooves 122, and the splicing inclined surfaces 121 of the two corner panels 120 are connected to complete the connection between the corner piece body 100 and the right-angle plug strip 200.

[0026] To avoid separation between the two corner panels 120, in one embodiment, the extension of the splicing inclined surfaces 121 of the two corner panels 120 are welded. Specifically, the outer right-angle positions of the two corner panels 120 after splicing and installation are welded and polished to form a seamless connection, and the above-mentioned connection position can also be oxidized. Since the corner piece structure is smaller in volume and lighter in weight than the overall aluminum alloy frame, it is easier to flip and rotate, etc., welding, polishing and oxidation treatment are convenient and easy to operate, avoiding the difficult operation of directly welding and oxidizing the corners of the aluminum alloy frame.

[0027] Of course, it is understandable that the two corner panels 120 may also be connected by gluing or screwing, and the embodiment of the utility model is not limited to this.

[0028] The inclination angle of the two splicing slopes 121 is not limited, as long as the two corner panels can form a right-angle structure when the two splicing slopes 121 are butted. It should be noted that one end of the corner panel 120 forms the above-mentioned splicing slope 121, and the other end is a plane that is attached to the end surface of the plate 300.

[0029] In one embodiment, a plurality of hollow parts 130 are formed inside the corner piece body 100. The provision of the hollow part 130 can save materials and reduce weight. The hollow part 130 can adopt a plurality of spaced through grooves, which is similar to a honeycomb reinforcement rib structure, which can save materials and reduce weight while still ensuring sufficient installation support strength and will not deform.

[0030] In one embodiment, a lamp trough 140 is formed on the inner side of the corner piece body 100, and the lamp trough 140 extends along the corner direction of the corner piece body 100. At the same time, a corresponding lamp trough 140 is also formed on the plate 300. When the corner piece body 100 is connected to the plate 300 via the right-angle plug strip 200, the lamp trough 140 on the corner piece body 100 is connected to the lamp trough 140 on the plate 300, and the LED light bar can be placed in the lamp trough 140 on the corner piece body 100 and the plate 300 to achieve the luminous lighting effect of the LED advertising light box.

[0031] In one embodiment, canvas slots 150 are formed on both side walls of the corner piece body 100, and the canvas slots 150 extend along the corner direction of the corner piece body 100. At the same time, a corresponding canvas slot 150 is also formed on the plate 300. When the corner piece body 100 is connected to the plate 300 via the right-angle plug-in strip 200, the canvas slots 150 on the corner piece body 100 are connected to the canvas slots 150 on the plate 300, and the advertising canvas of the LED advertising light box can be installed by inserting the edge of the advertising canvas into the corresponding canvas slots 150, and installing the canvas slots 150 on the LED advertising light box frame.

[0032] The right-angle plug strip 200 in this embodiment is a structure that connects two mutually perpendicular plates 300, so that the plates 300 are placed close to the corner piece body 100. The corner portion of the right-angle plug strip 200 is inserted into the right-angle slot 110, and both ends of the right-angle plug strip 200 extend out of the right-angle slot 110 and are connected to the plates 300.

[0033] In one embodiment, a hollow portion 130 is formed inside the right angle plug strip 200 .

[0034] In one embodiment, one end of the right angle plug strip 200 away from the corner piece body 100 is inserted into the connecting groove 310 formed on the plate 300. When connecting, the right angle plug strip 200 is inserted into the connecting groove 310 of the plate 300.

[0035] In order to facilitate fixing the right-angle plug-in strip 200 and the plate 300 , the present embodiment further includes a locking piece, which passes through the plate 300 and is connected to the right-angle plug-in strip 200 .

[0036] In one embodiment, the locking member includes a locking screw, which passes through a circular hole 320 formed on the plate 300 and is connected to a threaded hole 210 formed on the right-angle plug strip 200. The right-angle plug strip 200 is formed with a square groove 220 that is recessed inward, and the threaded hole 210 is located on the direction groove 220.

[0037] It is understandable that the locking member may be a fixing pin or other structure, as long as the fixing between the right-angle plug-in strip 200 and the plate 300 can be achieved, and the advantages are simple installation and stable connection.

[0038] Compared with existing technologies:

[0039] 1) Since the right-angle plug strip 200 is in a right-angle shape, it is embedded in the right-angle through groove 110 of the corner piece body 100, and the connection with the corner piece body 100 is firm and there is no risk of falling off;

[0040] 2) The corner piece structure only needs two corner plates 120 and a right-angle plug-in strip 200, with fewer parts and a simple structure;

[0041] 3) After the two corner panels 120 are spliced ​​and installed, the outer right-angle positions are welded and polished to form a seamless connection. At the same time, the above-mentioned connection positions can also be oxidized. Since the corner piece structure is smaller in volume and lighter in weight than the overall aluminum alloy frame, it is easier to flip and rotate. The welding, grinding and oxidation treatment are convenient and fast, and easy to operate, avoiding the difficult operation of directly welding and oxidizing the corners of the aluminum alloy frame.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
