Each guide rail 3 includes a guide portion 31, a first connecting portion 32, and a second connecting portion 33, located at opposite ends of the guide portion 31. During connection, the first connecting portion 32 snaps into the first connecting slot 10, and the second connecting portion 33 snaps into the second connecting slot 20. Each of the four corners of the top plate 1101 and the bottom plate is provided with a snap-fit ​​sleeve 61, and each of the first uprights 1 and the second uprights 2 is provided with two snap-fit ​​components 62. The two first uprights 1 and the two second uprights 2 are respectively connected to the top frame 5 and the bottom frame 4 via connecting structures, and are located at the four corners of the top frame 5 and the bottom frame 4. The two first uprights 1 are spaced apart along the long side of the top frame 5 and the bottom frame 4, and the first uprights 1 and the second uprights 2 are spaced apart along the short side of the top frame 5 and the bottom frame 4. The guide rails 3 of the two sets of storage component connecting structures are arranged facing each other.

[0049] The first partition column 8 and the second partition column 9 are connected between the top frame 5 and the bottom frame 4, with the first partition column 8 located between two first columns 1 and the second partition column 9 located between two second columns 2. Three first connecting grooves 10 are spaced apart along the length of each opposite side of the first partition column 8. Three second connecting grooves 20 are spaced apart along the length of each opposite side of the second partition column 9. A guide rail 3 connects the first partition column 8 and the second partition column 9 on the same side and at the same height. The guide rail 3 on one side of the first partition column 8 and the second partition column 9 faces the guide rail 3 between one of the first columns 1 and the second column 2 on that side, and the guide rail 3 on the other side of the first partition column 8 and the second partition column 9 faces the guide rail 3 between the other first columns 1 and the second column 2 on that side. A drawer 7 is slidably connected between the two opposing and equally positioned guide rails 3.

[0050] Please refer to Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the first partition column. Figure 9 This is a schematic diagram of the top frame. Further, the first partition column 8 includes a first column body 81 and an elastic connector 82. The elastic connector 82 is snapped into one end of the first column body 81, and a snap-fit ​​hole 50 is provided at the bottom of the top frame 5. One end of the elastic connector 82 elastically extends and retracts within the snap-fit ​​hole 50. The other end of the main body is connected to the bottom frame 4. At least one first connecting groove 10 is provided on each of the opposite sides of the first column body 81.

[0051] Please refer to Figure 10 , Figure 10 This is a cross-sectional view of the elastic connector 82. Further, the elastic connector 82 includes a base 821, a spring 822, and a movable connector 823. A movable groove 8210 is formed within the base 821. The bottom of the movable groove 8210 has a first limiting protrusion 824. One end of the spring 822 is fitted over the first limiting protrusion 824 to prevent displacement, and the spring 822 abuts against the bottom of the movable groove 8210. The movable connector 823 is movably disposed within the movable groove 8210, and the other end of the spring 822 abuts against the bottom of the movable connector 823. A snap-fit ​​protrusion 825 is formed on the top of the movable connector 823, and the snap-fit ​​protrusion 825 is disposed in the snap-fit ​​hole 50. It should be noted that in actual use, the first column 81 of different lengths can be replaced according to usage requirements to accommodate drawers 7 of different heights or different numbers of drawers 7.

[0052] In use, the end of the column away from the elastic connector 82 is placed against the bottom frame 4, and then the movable connector 823 is pressed, which compresses the spring 822 and causes the movable connector 823 to move relative to the movable groove 8210. Then, the snap-fit ​​protrusion 825 of the movable connector 823 is aligned with the snap-fit ​​hole 50 of the top frame 5, and the movable connector 823 is released. The spring 822 returns to its original position under the elastic force, and the spring 822 drives the movable connector 823 to return to its original position, so that the snap-fit ​​protrusion 825 extends into the snap-fit ​​hole 50, thereby completing the connection between the first partition column 8 and the bottom frame 4 and the top frame 5.

[0053] In this example, to facilitate pressing the movable connector 823, a pressing part 826 protrudes from one side of the movable connector 823. A sliding groove 8211 is provided on one side of the base 821, which is connected to the movable groove 8210. The pressing part 826 is movably disposed in the sliding groove 8211. In use, by applying force to the pressing part 826, the pressing part 826 moves downward along the sliding groove 8211, causing the movable connector 823 to compress the spring 822, causing the first limiting protrusion 824 to move downward. When the force is removed from the pressing part 826, the spring 822 returns to its original position under the elastic force, and drives the movable connector 823 to return to its original position upward, causing the pressing part 826 to return to its original position upward along the sliding groove 8211.

[0054] Please refer to Figure 11 and Figure 12 , Figure 11 This is a schematic diagram of the contact limit component. Figure 12 This is a schematic diagram of the base frame. To achieve a stable connection between the first partition column 8 and the base frame 4, the first partition column 8 also includes an abutment limiting member 83. The abutment limiting member 83 includes a locking seat 831 and a second limiting protrusion 832. The locking seat 831 is connected to the end of the first column 81 away from the elastic connector 82, and the second limiting protrusion 832 protrudes from the side of the locking seat 831 opposite to the first column 81. The base frame 4 has a corresponding limiting hole 40. When the abutment limiting member 83 is connected to the column, the locking seat 831 is locked to the end of the first partition column 8 away from the elastic connector 82. When the first partition column 8 is connected to the base frame 4, the second limiting protrusion 832 is inserted into the limiting hole 40, and the side of the locking seat 831 with the second limiting protrusion 832 abuts against the base frame 4. By providing an abutment limiting member 83 at the end where the column is connected to the bottom frame 4, the abutment limiting member 83 cooperates with the limiting hole 40 of the bottom frame 4 during connection, preventing the first partition column 8 from shifting relative to the bottom frame 4 and enhancing the stability of the connection between the first partition column 8 and the bottom frame 4.

[0055] Preferably, the abutting and limiting member 83 further includes an abutting piece 833, which is connected to the side of the snap-fit ​​base 831 where the second limiting protrusion 832 is provided, and the directions of the abutting piece 833 and the second limiting protrusion 832 are parallel to each other. When the first partition column 8 is connected to the base frame 4, the second limiting protrusion 832 is inserted into the limiting hole 40 of the base frame 4, and the abutting piece 833 abuts against the side of the base frame 4 to prevent the abutting and limiting member 83 from shifting relative to the base frame 4.

[0056] Please refer to Figure 13 , Figure 13 This is a perspective view showing the second partition column 9. The second partition column 9 includes a second column body 91 and two sets of snap-fit ​​structures 6. At least one second connecting groove 20 is provided on each of the opposite sides of the second column body 91. Both ends of the second column body 91 are connected to the top frame 5 and the bottom frame 4 respectively through the two sets of snap-fit ​​structures 6. That is, the connection method between the second partition column 9 and the top frame 5 and the bottom frame 4 is the same as the connection method between the first column 1 and the second column 2 and the top frame 5 and the bottom frame 4 respectively, and will not be described in detail here.

[0057] In another embodiment, one end of the second column 91 is provided with an elastic connector 82, and the other end is provided with an abutment limiting member 83, so that the connection method between the second partition column 9 and the top frame 5 and the bottom frame 4 is the same as the connection method between the first partition column 8 and the top frame 5 and the bottom frame 4 respectively.

[0058] Please reconsider. Figure 4 and Figure 5 The storage cabinet in this example also includes two third partition columns 12, two fourth partition columns 13, and a top panel assembly 11. The tops of the two first columns 1 and the two second columns 2 extend through the top frame 5. The top panel assembly 11 is located at the top of the two first columns 1 and the two second columns 2, and the four corners of the top panel assembly 11 are respectively engaged with the two first columns 1 and the two second columns 2. The upper surface of the top frame 5 is provided with a plurality of engagement holes 50 at intervals, and the lower surface of the top panel assembly 11 is correspondingly provided with a plurality of engagement holes 50. The two third partition columns 12 and the two fourth partition columns 13 are located between the top panel assembly 1101 and the top frame 5, with the two third partition columns 12 spaced apart between the two first columns 1 and the two fourth partition columns 13 spaced apart between the two second columns 2. Each third partition column 12 has a first connecting groove 10 on its opposite sides, and each fourth partition column 13 has a second connecting groove 20 on its opposite sides. A guide rail 3 is connected to each side of each third partition column 12 and its corresponding fourth partition column 13. By adding two first partition columns 8 and two second partition columns 9 between the top plate 1101 assembly 11 and the top frame 5, three drawers 7 can be horizontally arranged between the top plate 1101 assembly 11 and the top frame 5.

[0059] Please refer to Figure 14 and Figure 15 , Figure 14 This is an exploded view of the third partition column. Figure 15 This is an exploded view of the fourth partition column. In this example, the third partition column 12 includes an elastic connector 82, an abutment limiting member 83, and a third column 1201. The elastic connector 82 and the abutment limiting member 83 are respectively located at both ends of the third column 1201. First connecting grooves 10 are respectively provided on opposite sides of the third column 1201. The third column 1201 is movably connected between the top plate 1101 assembly 11 and the top frame 5 via the elastic connector 82 and the abutment limiting member 83, and its connection method is the same as that of the second partition column 9, which will not be described in detail here. It should be noted that the length of the third column 1201 can be changed as needed according to the number of drawers 7 connected. The fourth partition column 13 includes an elastic connector 82, an abutment limiting member 83, and a fourth column 1301. The elastic connector 82 and the abutment limiting member 83 are respectively located at both ends of the fourth column 1301. A second connecting groove 20 is provided on each of the opposite sides of the fourth column 1301. The connection method of the fourth partition column 13 is the same as that of the third partition column 12, and will not be described in detail here.

[0060] Please refer to Figure 16 , Figure 16 This is a schematic diagram illustrating the top plate assembly. The top plate assembly 11 includes a top plate 1101 and two connecting brackets 1102, which are respectively disposed on both sides of the bottom of the top plate 1101 along its length. The top plate 1101 is detachably connected to the two connecting brackets 1102 by screws. Each connecting bracket 1102 has a plug-in end 1103 at both ends. The two plug-in ends 1103 of one connecting bracket 1102 are respectively plugged into the top ends of two first columns 1, and the two plug-in ends 1103 of the other connecting bracket 1102 are respectively plugged into the top ends of two second columns 2. Furthermore, each plug-in end 1103, each first post 1 and each second post 2 are provided with a plug-in hole 11030. When the plug-in end 1103 is inserted into the end of the first post 1, the plug-in hole 11030 of the plug-in end 1103 corresponds to the plug-in hole 11030 of the first post 1. Then, by using a pin (not shown in the figure) to pass through the plug-in hole 11030 of the first post 1 and the plug-in hole 11030 of the plug-in end 1103 in sequence, the plug-in end 1103 is stably connected to the first post 1. When the plug end 1103 is plugged into the end of the second column 2, the plug hole 11030 of the plug end 1103 corresponds to the plug hole 11030 of the second column 2. Then, by using a pin to pass through the plug hole 11030 of the second column 2 and the plug hole 11030 of the plug end 1103 in sequence, the plug end 1103 is stably connected to the second column 2.

[0061] In summary, one end of the guide rail 3 is engaged with the first connecting groove 10 via the first connecting part 32, and the other end is engaged with the second connecting groove 20 via the second connecting part 33, thus connecting the guide rail 3 to the first column 1 and the second column 2 respectively. A third connecting part 33, perpendicular to the first connecting part 32, is provided at the end of the guide part 31 near the first connecting part 32, and the second connecting part 33 is detachably connected to the guide part 31. In actual use, by replacing different left-facing or right-facing second connecting parts 33, the guide rail 3 can be used both left and right. Engaging components 62 are connected to the first column 1 and the second column 2 respectively, and engaging sleeves 61 are provided on the top frame 5 and the bottom frame 4 respectively. The engagement of the engaging sleeves 61 with the engaging components 62 enables the first column 1 to be connected to the top frame 5 and the bottom frame 4 respectively. Thus, when installing the locker, there is no need to use screws or other fastening structures for connection, which effectively reduces assembly time and makes the assembly method of the locker simple, making it easy for users to assemble and disassemble.
