[0040] The shelf of the application will be described below in combination with Figures 1 to 5 The shelf of the application will be described below in combination with

[0041] According to the first aspect of the application, the shelf is provided. Please refer to Figure 1 and Figure 2 The shelf includes a base plate 100, two protective trims 200, and a plurality of protective pad units 300. The base plate 100 has opposite first and second side edges 110 and 120, and opposite third and fourth side edges 130 and 140. The two protective trims 200 are connected to the first and second side edges 110 and 120, respectively. Each protective trim 200 has at least one protective pad unit 300 at the end close to the fourth side edge 140, and the end of the protective pad unit 300 close to the fourth side edge 140 protrudes relative to the fourth side edge 140.

[0042] According to the shelf of the application, the first side edge 110 and the second side edge 120 of the base plate 100 are protected by the protective trim 200, and the fourth side edge 140 of the base plate 100 is protected by the end of the protective pad unit 300 close to the fourth side edge 140 protruding relative to the fourth side edge 140. When the shelf is installed from the first top plate to the inner wall surface of the box body, the protective trim 200 and the protective pad unit 300 can avoid the base plate 100 scratching the side wall or the bottom plate of the box body.

[0043] It can be understood that the base plate 100 is the main bearing part of the shelf, which is usually a flat plate structure for placing articles. In this embodiment, the base plate 100 has first and second side edges 110 and 120, and fourth and third side edges 130 and 140. The first and second side edges 110 and 120 are oppositely arranged on the left and right sides of the base plate 100, and the fourth and third side edges 130 and 140 are oppositely arranged on the front and rear sides of the base plate 100.
