[0052] like Figure 2As shown, the box opening 411 is arranged in front of the box body 41, the door body 10 is covered with the box opening 411, and the right end of the top surface of the door body 10 is connected to the box body 41. The first shaft hole 111 is opened vertically downward to enable the door body 10 to rotate in the horizontal direction. The top surface of the door body 10 and the top surface of the box body 41 both extend in the horizontal direction, the first shaft hole 111 extends downward in the vertical direction, and the first connecting shaft 21 is inserted parallel to the first shaft hole 111, so that the door body 10 rotates in the horizontal direction around the first connecting shaft 21. The first protruding end 22 is in the shape of a thin plate, wherein the lower plate surface of the first protruding end 22 is perpendicular to the axis of the first connecting shaft 21, and the lower plate surface of the first protruding end 22 is fixedly connected to the top surface of the box body 41, so that the first connecting shaft 21 extends in the vertical direction to ensure that the door body 10 rotates in the vertical direction.
[0053] Optionally, the door body 10 includes a first door body 13 and a second door body 14. The first door body 13 is covered on the box opening 411, and the first shaft hole 111 is opened at the upper end of the first door body 13, and the upper end periphery of the first shaft hole 111 protrudes upward to form a first hollow shaft 131; the second door body 14 is covered on the first door body 13 to form a double-layer door with the first door body 13; the first rotating shaft structure 11 also includes a second connecting shaft 112 and a second protruding end 113 perpendicular to the axis of the second connecting shaft 112, wherein the second connecting shaft 112 is sleeved outside the first hollow shaft 131, and the second protruding end 113 is fixedly connected to the second door body 14; wherein the axis of the first shaft hole 111 is offset by a first distance relative to the axis of the first connecting shaft 21 along the width direction of the door body 10 toward the center of the door body 10; the axis of the second connecting shaft 112 is offset by a first distance relative to the axis of the first hollow shaft 131 along the width direction of the door body 10 toward the center of the door body 10.
[0054] like Figure 2 and Figures 4 to 7 As shown, the first door body 13 and the second door body 14 are sequentially covered with the box opening 411, and the second door body 14 is covered outside the first door body 13 to form a double door. The first axial hole 111 is opened from the top surface of the first door body 13 downward in the vertical direction, and the upper end of the first axial hole 111 protrudes upward from the top surface of the door body 10 to form a first hollow shaft 131, and the second door body 14 is connected to the first hollow shaft 131 through the second connecting shaft 112. One end of the second connecting shaft 112 is fixedly connected to the side end of the second door body 14 so that the upper end surface of the second door body 14 is flush with the upper end surface of the first door body 13. The other end of the second connecting shaft 112 is adapted to the first hollow shaft 131 and is sleeved on the outside of the first hollow shaft 131, so that the second door body 14 can rotate around the first hollow shaft 131 to open or close the second door body 14. As shown Figure 2As shown in Figure H, the first door body 13 and the second door body 14 are both connected to the box body 41 at the right end, and the left end rotates with the opening and closing of the door body 10.

In this case, the axis of the first connecting shaft 21 is offset toward the left relative to the axis of the first axial hole 111 so that the upper end of the door body 10 is pushed to the left so that the right end of the door body 10 bulges upward to prevent the right end of the door body 10 from sagging during use. In summary, the offset direction of the axis of the first connecting shaft 21 of the door body 10 relative to the axis of the first axial hole 111 of the door body 10 is the same as the direction of the fixed side of the door body 10, that is, toward the direction away from the rotating end of the door body 10, so that the rotating end of the door body 10 is forced to bulge upward to prevent the rotating end of the door body 10 from sagging. The axis of the first hollow shaft 131 of the door body 10 is offset relative to the axis of the second connecting shaft 112 in a direction away from the rotating end of the door body 10. Since the first door body 13 and the second door body 14 have the same opening direction, the axis of the first hollow shaft 131 and the axis of the first connecting shaft 21 are offset in the same direction.
[0056] Optionally, the first rotating shaft structure 11 further includes a shaft sleeve 114. The shaft sleeve 114 is detachably mounted on the upper end of the door body 10; the second rotating shaft structure 20 is adapted to the shaft sleeve 114 to rotatably connect the door body 10 and the box body 41.
