Description

Combined pallet

The present invention relates to a pallet structure, and more particularly to a combined pallet structure.

In the transportation or management of goods, the pallet is a very common auxiliary tool for the supply of goods, and then transported by machines (such as stackers), in addition to being convenient and fast, it can also avoid the goods being transported or stored. The process is damaged or damp.

However, most of the plastic pallets currently on the market are integrally formed. If different sizes of plastic pallets are to be used, there must be corresponding molds to be manufactured, but the mold costs are very expensive. In addition, when the pallet is packed from the square, the board surface is easily cracked. In addition, the pallet is also easily damaged by collision. Whether the board surface is cracked or a small corner is missing, the entire pallet will be scrapped and cannot be scrapped. continue to use. Therefore, how to make a pallet that is low in cost and easy to maintain has been a problem that those skilled in the art are eager to solve.

In view of the above problems, the present invention provides a combined pallet comprising: a pallet frame comprising a plurality of straight rods and a plurality of cross bars, the straight bars and the cross bars respectively having a stepped positioning portion; The pedestal is located at an end corner of the pallet frame, and each of the first pedestals includes: a first base body, a first upper end surface, a first lower end surface, and a plurality of first side end surfaces, The first end surface is connected to the first upper end surface and the first lower end surface; and the plurality of first stepped joints are located between the first upper end surface of the first base body and two of the first side end surfaces The first stepped joints are connected, and the stepped positioning portion of one of the straight rods is guided to the position and the stepped positioning portion of one of the cross bars is combined with the straight rod and the cross rod On the first base body, a plurality of second bases are respectively located between the two first bases, and each of the second bases includes: a second base body including a second upper end surface, a second lower end surface and a plurality of second side end surfaces, the second side end surfaces are connected to the a second upper end surface and the second lower end surface; and a second stepped joint portion between the second upper end surface of the second base body and one of the second side end surfaces, the second stepped joint portion Aligning the stepped positioning portion of one of the straight rods or the stepped positioning portion of one of the cross rods to engage the straight rod or the cross rod on the second base body; and a panel portion, The first upper end surface of the first base and the second upper end surfaces of the second bases are fixed to the pallet frame.
