[0050] When the extended storage rack 2 is spliced ​​with the main storage rack 1 along the length direction of the main storage layer plate 11, the sides of the extended storage layer plate 21 on the extended storage rack 2 along the length direction will be close to and adjacent to the sides of the main storage layer plate 11 of the corresponding height or number of layers along the length direction, and then the two first U-shaped plates 31 respectively wrap the two ends of the sides of the main storage layer plate 11 along the length direction, and the two second U-shaped plates 32 respectively wrap the two ends of the sides of the extended storage layer plate 21 along the length direction and adjacent to the first U-shaped plate 31, and then the first U-shaped plate 31 and the corresponding second U-shaped plate 32 are assembled and fixed, so that the main storage rack 1 and the extended storage rack 2 are arranged side by side on the main storage layer plate 11 along the length direction to form a combined storage rack, which can improve the stability and neatness of the combined storage rack, and the assembly process between the first U-shaped plate 31 and the corresponding second U-shaped plate 32 is simple and efficient.

[0051] Specifically, the specific structure of the first U-shaped plate 31 can be referred to in the attached Figure 4-5 The first U-shaped plate 31 includes a first bottom plate 311 , and two ends of one side of the first bottom plate 311 are respectively provided with a first extension plate 312 and a second extension plate 313 extending outward in the same direction.

[0052] A first protrusion 314 is provided in the middle of the first extension plate 312 along the extension direction of the first bottom plate 311 , and a first slot 315 is formed in the middle of the second extension plate 313 inwardly concave corresponding to the first protrusion 314 .

[0053] Specifically, the specific structure of the second U-shaped plate 32 can be referred to in the attached Figure 4 The second U-shaped plate 32 includes a second bottom plate 321 , and two ends of one side of the second bottom plate 321 are respectively provided with a third extension plate 322 and a fourth extension plate 323 extending outward in the same direction.

[0054] A second protrusion 324 is extended outwardly from the middle portion of the third extension plate 322 corresponding to the first locking groove 315 , and a second protrusion 324 is recessed inwardly from the middle portion of the fourth extension plate 323 corresponding to the first locking groove 314 to form a second locking groove 325 .

[0055] The first protrusion 314 can be matched and snapped into the second snapping groove 325 , and the second protrusion 324 can be matched and snapped into the first snapping groove 315 , so that the first U-shaped plate 31 and the second U-shaped plate 32 are in a connected state.

[0056] In this way, when the first U-shaped plate 31 wraps around the sides of the main storage layer 11 along the length direction, and the second U-shaped plate 32 wraps around the sides of the extended storage layer 21 along the length direction and adjacent to the first U-shaped plate 31, the first protrusion 314 of the first U-shaped plate 31 can be matched and snapped into the second slot 325 of the second U-shaped plate 32, and the second protrusion 324 of the second U-shaped plate 32 can be matched and snapped into the first slot 315 of the first U-shaped plate 31, so that the first U-shaped plate 31 and the second U-shaped plate 32 can fit tightly together to form a ring, tightly connecting the sides of the main storage layer 11 along the length direction and the sides of the extended storage layer 21 along the length direction, thereby improving the stability of the combined storage rack, and also simplifying the assembly process between the first U-shaped plate 31 and the corresponding second U-shaped plate 32.
