[0004] However, in this application, the two plates are connected by two connecting plates and a hinge seat, which invisibly increases the overall volume of the pallet. In addition, the rod is inserted into the connection port and fixed by a thread, which may fall off and become loose after long-term use, posing a risk of disconnection. At the same time, a separate placement hole is provided for the rod. In daily use of this pallet, the rod is in a plugged-in state and is not disassembled frequently, so the provision of the placement hole increases the processing cost. Utility Model Content

[0026] The first hinge shaft 330 is simultaneously plugged into the connection end of the first hinge seat 2 . In this way, the first connecting block 3 is hinged to the first hinge seat 2 via the first hinge shaft 330 .

[0027] The other ends of the two first ear plates 31 are vertically provided with a first block 32 , and a first connecting hole 331 is formed on one side of the first block 32 .

[0028] The second connecting block 34 includes two second ear plates 340 hinged at the connecting end of the second hinge seat 22 and symmetrically spaced apart. The two second ear plates 340 are respectively located at two side surfaces of the connecting end of the second hinge seat 22 .

[0029] A second insertion hole 342 is defined in the second ear plate 340 , and a second hinge shaft 343 is inserted into the second insertion hole 342 .

[0030] The second hinge shaft 343 is simultaneously plugged into the connecting end of the second hinge seat 22 . In this way, the second connecting block 34 is hinged to the second hinge seat 22 via the second hinge shaft 343 .

[0031] The other ends of the two second ear plates 340 are vertically provided with a second block 341 , and a second connecting hole 344 is formed on one side of the second block 341 .

[0032] The second connection hole 344 and the first connection hole 331 are located at the same straight line as each other.

[0033] The insertion rod 4 includes a rod body 45 inserted into all the first connection holes 331 and the second connection holes 344 .

[0034] A baffle 41 is vertically arranged at one end of the rod body 45 , and a cone 43 is provided at the other end of the rod body 45 . A pin hole 42 is opened on the outer surface of the rod body 45 near the cone 43 , and a baffle pin 44 is inserted into the pin hole 42 .

[0035] In this embodiment, the outer diameter of the rod body 45 is smaller than the sizes of the first connecting hole 331 and the second connecting hole 344 . This design ensures that the first connecting block 3 and the second connecting block 34 can rotate around the rod body 45 .

[0036] The first hinge seat 2 and the second hinge seat 22 are arranged alternately, and the first connecting block 3 and the second connecting block 34 are arranged alternately.

In this design, the first connecting block 3 and the second connecting block 34 are connected together, that is, the first plate body 1 and the second plate body 11 are connected together. At the same time, under the action of the first hinge seat 2 and the second hinge seat 22, the first plate body 1 and the second plate body 11 can rotate with each other.

[0039] The cone 43 is used to facilitate the rod 45 to enter the first connecting hole 331 and the second connecting hole 344 smoothly.

[0040] The items to be transported are then placed on the corresponding anti-slip pads 6 , and the items are transported under the action of the universal wheels 5 .

[0041] When the tray is used up, the first plate 1 is lifted up, and under the action of the first hinge 2, the second hinge 22 and the insertion rod 4, the first plate 1 and the second plate 11 are rotated and folded and then placed, thus reducing the area occupied by the placement.

[0042] When there are fewer items to be transferred and only an area the size of the first plate body 1 or the second plate body 11 is required, first pull out the stop pin 44, and then pull out the insertion rod 4 from the first connecting hole 331 and the second connecting hole 344, so that the first plate body 1 and the second plate body 11 are separated, and then the first hinge shaft 330 is pulled out from the first plug hole 33 in turn, that is, the first connecting block 3 is removed, and then the first plate body 1 is used to transport items. It is easy to operate and has a wide range of applications.
