[0036] In the existing construction field, aluminum alloy grilles, as a common decorative material, are widely used in indoor and outdoor decoration, such as outdoor decoration, sunshade grilles, indoor grille partitions, grille ceilings, etc. Traditional aluminum alloy grilles have some problems in processing, installation and use.

[0037] Traditional narrow-edge grille connection processes such as clamping and welding easily expose the connecting parts to external influences and damage, thereby increasing the maintenance cost of the grille. At the same time, the exposed connecting parts make it impossible to guarantee the appearance quality of the narrow-edge grille, which in turn affects the aesthetics of the grille.

[0038] The utility model provides a narrow-edge grille structure.

[0039] See also Figure 1 , Figure 3 and Fig. 9 In one embodiment of the utility model, the narrow-side grille structure comprises a plurality of grille modules 1, wherein the grille module 1 has a first side 11 and a second side 12 arranged opposite to each other along a first direction, and the first side 11 and the second side 12 of the grille module 1 are both provided with a first connecting portion 111, and any two adjacent grille modules 1 are spliced ​​with each other through the first connecting portion 111 to form a grille system 2;

[0040] The grille system 2 has a first side wall 21 and a second side wall 22 which are arranged opposite to each other along a second direction, and the first side wall 21 and the second side wall 22 of the grille system 2 are both installed with the cover member 3; and

[0041] Side piece 4, the grille system 2 has a third side wall 23 and a fourth side wall 24 arranged opposite to each other along the first direction, and the third side wall 23 and the fourth side wall 24 of the grille system 2 are both installed with the side piece 4; wherein the first direction intersects with the second direction;

[0042] The technical solution of the utility model adopts any two adjacent grille modules 1 to be spliced ​​together through the first connecting part 111 to form a grille system 2, and the peripheral side walls of the grille system 2 are enclosed by arranging the buckle cover parts 3 and the side parts 4, so that the exposed connecting parts on the grille module 1 are covered, thereby avoiding the exposed connecting parts from being damaged by external influences, thereby increasing the service life of the connecting parts, thereby reducing the complexity and cost of grille installation, and at the same time ensuring the appearance quality of the narrow-edge grille, thereby improving the aesthetics of the grille.

[0043] In this embodiment, any two adjacent grille modules 1 are spliced ​​together through the first connection portion 111 of the first side 11 or the second side 12, so that multiple grille modules 1 are spliced ​​in sequence along the first direction to form a grille system 2. Compared with the complicated welding connection process in the traditional narrow-side grille, the multiple grille modules 1 of the present application are spliced ​​together through the adjacent first connection portions 111, so that the splicing and assembly between the multiple grille modules 1 is simple, thereby reducing the complexity and cost of installing the multiple grille modules 1. At the same time, each grille module 1 can be designed modularly, so that the shape and size of each grille module 1 are the same, so that each grille module 1 can be processed modularly during production, thereby improving the production efficiency of the grille module 1. In addition, since the shape and size of each grille module 1 are designed to be the same, and the splicing and assembly between the multiple grille modules 1 are simple, when one of the grille modules 1 is damaged, the maintenance personnel can quickly disassemble the damaged grille module 1 and replace it with a new grille module 1, thereby improving the maintenance efficiency of the grille system 2. The grille system 2 can control the size of the grille system 2 to match the actual required area size by limiting the number of grille modules 1 involved in the splicing according to the actual required area size of the installation site, so that the grille system 2 can be flexibly adjusted and combined, so that the grille system 2 is more in line with the size required by the use scene, thereby improving the adaptability and aesthetics of the grille system 2.
