As shown in FIGS. 1-12, an adjusting mechanism of a box includes a first adjusting structure 10 and a second adjusting structure 20. The first adjusting structure 10 includes a first base 11, a rotating member 12 arranged on the first base 11, an adjusting lock hook 14 movably arranged on the rotating member 12 and a driving member 13 arranged in the rotating member 12 and driving the adjusting lock hook 14 to move. The rotating member 12 drives the adjusting lock hook 14 to rotate when rotating, such that the adjusting lock hook 14 has a locking position and an unlocking position. The second adjusting structure 20 includes a second base 21 and an adjusting rod 22 movably arranged in the second base 21, where the adjusting lock hook 14 is in the locking position (shown in FIG. 14) when the adjusting lock hook 14 cooperates with the adjusting rod 22, and the adjusting lock hook 14 is in the unlocking position (shown in FIG. 16) when the adjusting lock hook 14 is separated from the adjusting rod 22.

By using the technical solution of the embodiment, the rotating member 12 drives the adjusting lock hook 14 to rotate when rotating, such that the adjusting lock hook 14 has the locking position and the unlocking position. The adjusting lock hook 14 is in the locking position when the adjusting lock hook 14 cooperates with the adjusting rod 22, and the adjusting lock hook 14 is in the unlocking position when the adjusting lock hook 14 is separated from the adjusting rod 22. The first adjusting structure 10 is arranged on one of the two adjacent boxes and the second adjusting structure 20 is arranged on the other one of the two adjacent boxes. In the embodiment, when the adjusting lock hook 14 is in the locking position, the driving member 13 moves to drive the adjusting lock hook 14 to move in a direction perpendicular to an axis of the adjusting rod 22, so as to adjust a distance between the first adjusting structure 10 and the second adjusting structure 20, and further a gap between the two adjacent boxes may be adjusted. The adjusting rod 22 rotates to push the adjusting lock hook 14 to move in an axial direction of the adjusting rod 22, so as to adjust the distance between the first adjusting structure 10 and the second adjusting structure 20, and further a height difference between the two adjacent boxes may be adjusted. In this way, by one adjusting mechanism of a box, the gap between the two adjacent boxes may be adjusted, and the height difference between the two boxes may also be adjusted, which makes functions diverse, operation simpler and more convenient and work efficiency higher. Thus, the technical solution of the embodiment may solve the problem that in the related art, only a gap between adjacent boxes may be adjusted, which makes a function relatively single.

It should be noted that in the case where the two adjacent boxes are arranged on a wall, “a direction perpendicular to an axis of the adjusting rod 22” described above is a direction parallel to a surface of the wall, and “an axial direction of the adjusting rod 22” described above is a direction perpendicular to the surface of the wall.

The first operating hole 151 on the operating plate 15 is rotated by an Allen wrench, the operating plate 15 drives the rotating member 12 to rotate clockwise around the front-back direction (the Z-axis direction shown in FIG. 11) in the first mounting hole 111, then the adjusting lock hook 14 rotates around a Z-axis, and when the adjusting lock hook rotates by 90 degrees, the lock hook section 142 cooperates with the lock groove 222 to make the adjusting lock hook 14 in the locking position, thus the first box and the second box are fixedly connected.

The driving rod 132 on the first box is rotated clockwise or counterclockwise by an Allen wrench to drive the driving block 131 to move in the front-back direction (a Z-axis positive direction or a Z-axis negative direction shown in FIG. 11), thereby driving the adjusting lock hook 14 to move in the left-right direction (an X-axis positive direction or an X-axis negative direction shown in FIG. 11). By a pushing force or a pulling force, on the rod body 221 on the second box, of the lock hook section 142 of the adjusting lock hook 14 on the first box, the second box is driven to move in the left-right direction, and finally a gap between the first box and the second box in the left-right direction is adjusted.

The adjusting rod 22 on the second box is rotated clockwise or counterclockwise by an Allen wrench to move the adjusting rod 22 in the front-back direction (the Z-axis positive direction or the Z-axis negative direction). By the cooperation between the lock groove 222 on the adjusting rod 22 on the second box and the lock hook section 142 on the first box, the adjusting lock hook 14 on the first box is pushed or pulled to move in the front-back direction, such that the first box is driven to move in the front-back direction relative to the second box, and finally, a height difference between the first box and the second box in the front-back direction is adjusted.

In addition, the second side portion of the third box is connected with the fourth side portion of the fourth box by another adjusting mechanism of a box. The driving rod on the third box is rotated clockwise or counterclockwise by an Allen wrench to drive the driving block to move in the front-back direction (the Z-axis positive direction or the Z-axis negative direction shown in FIG. 11), such that the adjusting lock hook is driven to move in the up-down direction (a Y-axis positive direction or a Y-axis negative direction shown in FIG. 13). By a pushing force or a pulling force, on the rod body on the fourth box, of the lock hook section of the adjusting lock hook on the third box, the fourth box is driven to move in the up-down direction, and finally a gap between the third box and the fourth box in the up-down direction is adjusted.
