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 steps a first joint between the first upper end surface of the first base body and the first one of the first side end faces, wherein the first stepped joints are connected, and one of the straight portions is guided The stepped positioning portion of the rod and the stepped positioning portion of the one of the cross bars combine the straight rod and the cross rod on the first base body; the plurality of second bases are respectively located at the two first Each of the second bases includes: a second base body, a second upper end surface, a second lower end surface, and a plurality of second side end surfaces, wherein the second side end surfaces are connected to the second An 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 Positioning the stepped positioning portion of one of the straight rods or the stepped positioning portion of one of the cross rods to join the straight rod or the cross rod to the second base body; and a panel portion, fixed On the pallet frame, and fitting the pallet frame, the first of the first pedestals A second end face on the plurality of the plurality of second base end surface.

The invention adopts a stepped structure design, and can guide the straight rod and the cross rod to be aligned with the straight rod and the cross rod on the base during assembly, which means that the straight rod and the cross rod are first formed into a pallet frame. The step-by-step structure is used to design the aligning guide pallet frame combined with the pedestal. The aligning guide straight rod and the crossbar can be combined with the pedestal in a stepped structure, and then the straight rod and the cross rod are combined into a pallet frame. Therefore, the stepped structure design is used as an assembled foolproof design, which does not skew or protrude during assembly, and improves assembly convenience and assembly efficiency. In addition, when some components are damaged, only the damaged components need to be replaced, which effectively saves maintenance procedures and reduces maintenance costs.
