[0054] Embodiment 5:

[0055] The expandable wine rack of the present embodiment is shown in FIG. 7, which is different from the embodiment 3 in that the structure of the connecting piece 3 is different. In the present embodiment, the connecting piece 3 adopts the structure of the third connecting piece 6 as shown in FIG. 8.

[0057] In this embodiment, the number of support columns 1 in each support unit can also be freely increased or decreased to adjust the length of the expandable wine rack of this utility model.

[0058] Example 6:

[0059] like Figure 10 As shown, the difference between the expandable wine rack in this embodiment and embodiment 3 is that the support unit includes three support columns 1. The connectors 3 on the left and right support columns 1 adopt the first connector 4, and the connectors 3 on the middle support column 1 adopt the third connector 6. This not only facilitates the expansion of the number of support columns 1 in the support unit, but also saves the raw material cost of the connectors 3.

[0060] Example 7:

[0061] like Figure 11 As shown, the difference between the expandable wine rack in this embodiment and embodiment 5 is that the connectors 3 on the left and right side support columns 1 of the support unit are second connectors 5, and the connectors 3 on the middle support column 1 are fourth connectors 7. This not only facilitates the expansion of the number of support columns 1 in the support unit, but also saves on the raw material cost of the connectors 3.

[0062] Example 8:

[0063] like Figure 12As shown, the difference between the expandable wine rack in this embodiment and Embodiment 1 is that, in two adjacent support units, multiple first support crossbars 9 are provided between the two opposing support columns 1. This prevents the support columns 1 from tilting forward or backward, ensuring the structural stability of the two adjacent support units. The number of first support crossbars 9 between the two support columns 1 is determined by the length of the support columns 1, and can be spaced 50cm or 100cm apart. Each end of the first support crossbar 9 has a support rod connector 8, which is detachably connected to both the support column 1 and the first support crossbar 9.

[0064] To facilitate the connection of the first support crossbar 9 to any position of the support column 1, the support rod connector 8 can adopt a structure similar to the first connector 4 or the second connector 5. Specifically, the support rod connector 8 has a groove for connecting the support column 1, allowing the support column 1 to be inserted into the groove and then tightened with screws. A connecting hole is provided at one end of the support rod connector 8 for connecting the end of the first support crossbar 9, allowing the end of the first support crossbar 9 to be inserted into the connecting hole and also tightened with screws. Since the first support crossbar 9 has a different size than the wine rack beam 2, the support rod connector 8 also differs in structural dimensions from the first connector 4 or the second connector 5.

[0065] Example 9:

[0066] like Figure 13 As shown, the difference between the expandable wine rack in this embodiment and Embodiment 1 is that, in the same support unit, at least one second support crossbar 10 is provided between two adjacent support columns 1 on the left and right sides. This can prevent the support columns 1 from tilting left and right, so that the support unit can maintain structural stability. The number of second support crossbars 10 provided between the two support columns 1 on the left and right sides is set according to the length of the support columns 1, and a second support crossbar 10 can be provided at intervals of 50cm or 100cm. Both ends of the second support crossbar 10 are provided with support rod connectors 8, and the support rod connectors 8 and the second support crossbars 10 are detachably connected.

[0067] To facilitate the connection of the second support crossbar 10 to any position of the support column 1, the support rod connector 8 can adopt a structure similar to the first connector 4 or the second connector 5. Specifically, the support rod connector 8 has a groove for connecting the support column 1, allowing the support column 1 to be inserted into the groove and then tightened with screws. A connecting hole is provided at one end of the support rod connector 8 for connecting the end of the second support crossbar 10, allowing the end of the second support crossbar 10 to be inserted into the connecting hole and also tightened with screws. Since the second support crossbar 10 differs in size from the wine rack beam 2, the support rod connector 8 also differs in structural dimensions from the first connector 4 or the second connector 5.

[0068] Example 10:

[0069] like Figure 14 As shown, the difference between this embodiment of the expandable wine rack and Embodiment 1 is that at least one first support crossbar 9 is provided between two opposing support columns 1, and at least one second support crossbar 10 is provided between two adjacent support columns 1. This prevents the support columns 1 from tilting left or right or forward or backward, ensuring that the support columns 1 remain upright and thus maintaining the structural stability of the entire expandable wine rack. Each support column 1 is provided with at least one support rod connector 8. The first support crossbar 9 and the second support crossbar 10 are both connected to the support column 1 through the support rod connector 8. The support rod connector 8 is detachably connected to the support column 1, the first support crossbar 9, and the second support crossbar 10.

[0070] The support rod connector 8 can adopt a structure similar to the third connector 6 or the fourth connector 7. A groove for connecting the support column 1 is provided on the support rod connector 8, allowing the support column 1 to be embedded in the groove and then tightened with screws. A connecting hole for connecting the end of the second support crossbar 10 is provided on one side of the support rod connector 8, allowing the end of the second support crossbar 10 to be inserted into the connecting hole and then tightened with screws. A connecting hole for connecting the end of the first support crossbar 9 is provided on the other side of the support rod connector 8, allowing the end of the first support crossbar 9 to be inserted and then tightened with screws. Because the first support crossbar 9 is connected to the support rod connector 8 at different positions, the support rod connector 8 differs structurally from the third connector 6 or the fourth connector 7.
