Description

Technical Field

[0001] The present invention relates to the technical field of logistics, and in particular to a logistics transfer box. Background Art

[0002] Transfer boxes are boxes that we often use to transport goods in our lives. Existing transfer boxes are generally fixed in form. When people need to take out the goods in the transfer box, they generally need to turn the entire transfer box over to pour out the goods, which is quite troublesome.

When the number of box bodies 2 is large, multiple bottom plates 1 are used, and the dovetail blocks 11 are clamped in the dovetail grooves 10 of adjacent bottom plates 1. According to the needs of use, the multiple bottom plates 1 are flattened into a rectangular or other irregular bottom surface. Then, a number of box bodies 2 are placed on each bottom plate 1, and the multiple box bodies 2 on each bottom plate 1 are stacked in the vertical direction. The box bodies 2 are stacked in a corresponding number according to the needs of use. Finally, multiple top plates 3 are sequentially covered on the topmost box body 2.

[0039] To improve the connection reliability between the bottom plate 1, top plate 3 and box 2, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 18 In this embodiment, the boxes 2, the bottom plate 1, and the top plate 3 are all detachably connected. The box 2 includes a horizontal partition 23, four columns 21 fixed to the partition 23, and a wall panel 22. A wall panel 22 is located between two adjacent columns 21. The four columns 21 and the four wall panels 22 constitute the side walls of the transfer box. Specifically, the transfer box is a rectangular parallelepiped, and the side walls of the transfer box form a rectangle. The columns 21 are located at the four vertices of the rectangle, and the wall panels 22 are located at the four sides of the rectangle.

[0040] Furthermore, a shaft 20 is rotatably connected in the column 21, and the shaft 20 longitudinally passes through the box body 2. A connecting component 4 is provided between the bottom plate 1, the top plate 3 and the box body 2, wherein the connecting component 4 includes the following: a locking block 41 is provided at the top of the shaft 20, a locking block 12 is rotatably connected to the bottom plate 1, and a connecting groove 40 is provided at the bottom of the top plate 3 and the bottom of the box body 2. The connecting groove 40 includes an unlocking groove 402 and a locking groove 403.

In the unlocking groove 402, the bottom plate 1, the top plate 3 and several box bodies 2 can be separated from each other; when the present invention is in a locked state, the locking block 41 / locking block 12 is in the locked position, and the locking block 41 / locking block 12 is located in the locking groove 403. At this time, when the top plate 3 is lifted, the bottom wall of the locking block 41 / locking block 12 abuts against the bottom wall of the locking groove 403, and the bottom plate 1, the top plate 3 and several box bodies 2 are fixedly connected to each other, which has a good fixed connection effect, high stability, will not loosen or detach, and the box body 2 located above will not fall, thereby protecting the goods well.

[0041] Furthermore, in order to facilitate unlocking / locking, it is necessary to drive the four shafts 20 to rotate to the unlocking state / locking state at the same time, please refer to Figure 4 、 Figure 5 and Figure 8 Four rotating blocks 34 are rotatably connected within the top plate 3 (the four rotating blocks 34 are located at the four corners of the top plate 3, corresponding one-to-one to the positions of the rotating shaft 20). A driving mechanism for driving the rotating blocks 34 to rotate is provided within the top plate 3. The driving mechanism includes a turntable 32 rotatably connected to the top plate 3, and a connecting rod 33 hinged to the turntable 32 for driving the rotating blocks 34 to rotate. The rotating blocks 34 are hinged to the connecting rod 33. An operating rod 31 is fixed to the turntable 32, and the top end of the operating rod 31 extends to the upper side of the top plate 3. When the operating rod 31 is rotated, the operating rod 31 drives the turntable 32 to rotate, and the turntable 32 pulls / pushes the connecting rod 33, causing the four rotating blocks 34 to rotate simultaneously. Attention should be paid to the angle at which the connecting rod 33 is set to prevent the connecting rod 33 from locking.
