Description

  The present invention relates to a pallet structure, and more particularly to a size-adjustable assembly pallet.

  Since most of the generally known plastic pallets are integrally molded, when using plastic pallets of different sizes, it was necessary to manufacture them with suitable molds. However, if the mold cost is very high and the pallet is damaged due to a collision, the entire pallet has to be discarded even if it is small. How to manufacture a pallet having a high utilization rate at a low cost has been a problem to be solved by those skilled in the art.

  An object of the present invention is to provide a size-adjustable assembly-type pallet that can adjust the size in the horizontal direction and the vertical direction in order to solve the above-described problems of the prior art.

  In the present invention, each base includes a base body, a plurality of grooves, and a plurality of positioning insertion holes, the plurality of grooves are located in the base body, and the plurality of positioning insertion holes are in the plurality of grooves. The plurality of positioning insertion holes are deeper than the plurality of groove depths, and each connecting rod includes a main pillar portion and a plurality of bent pipe insertion portions. The pipe insertion part is curved and extended in the same direction from both ends of the main pillar part, and is inserted into a plurality of positioning insertion holes of two bases, and at least a part of the main pillar part is in a plurality of grooves. Providing a size-adjustable assembly-type pallet that includes a plurality of connecting rods that are fixed to both ends of the connecting rods and a plurality of flat plates that are fixed to the plurality of bases. To do.

  In the present invention, each base includes a base body, a plurality of grooves, and a plurality of positioning insertion holes, the plurality of grooves are located in the base body, and the plurality of positioning insertion holes are in the plurality of grooves. The plurality of positioning insertion holes are deeper than the plurality of groove depths, and each connecting rod includes a main pillar portion and a plurality of bent pipe insertion portions. The pipe insertion part is curved and extended in the same direction from both ends of the main pillar part, and is inserted into a plurality of positioning insertion holes of two bases, and at least a part of the main pillar part is in a plurality of grooves. A size-adjustable assembly-type pallet including a plurality of connecting rods that are fixed to both ends of the connecting rods and a plurality of flat plates fixed to the connecting rods is also provided. To do.

  The size adjustable assembly pallet of the present invention has the following advantages. By inserting the bent tube insertion part of the connecting rod into different insertion holes on the base, the distance between both bases can be adjusted, and the dimensions in the horizontal and vertical directions of the assembly pallet can be adjusted. It can be freely assembled and adjusted according to actual needs, and is very flexible and convenient. When the base breaks due to a collision, it can be replaced with a new base, and the pallet utilization rate is increased to two or more times, so that the cost can be greatly reduced. Further, the inside of the base has a beam columnar structure. For example, by adopting an H shape, an I shape, or an X shape, the strength of the support can be significantly increased while reducing the weight of the base. In addition, the connected base and connecting rod can form a flat frame, so that the structure of the frame is strong and stable, and there is no movement or displacement between the parts. It is also very safe when you do.

The size-adjustable assembly-type pallet 1 of the present invention includes a plurality of bases 20, a plurality of connecting rods 30A, and a plurality of panels 50A.

The base 20 is made of plastic extrusion, and includes a base body 23, a plurality of grooves 21, and a plurality of positioning insertion holes 22. The plurality of grooves 21 are positioned in the base body 23, and the grooves 21 are horizontal. It is provided with a vertical (FIGS. 6A and 6B) or diagonal direction (FIG. 6C). The plurality of positioning insertion holes 22 are located on the inner side surfaces of the plurality of grooves 21, and the depths of the plurality of positioning insertion holes 22 are deeper than the depths of the plurality of grooves 21. As shown in FIG. 4, a plurality of insertion holes 22 are provided at the intersection or predetermined position of the groove 21. In addition to this, the base 20 can be formed in various shapes such as a rectangular parallelepiped (FIGS. 6A and 6B), a rectangular parallelepiped or a cylindrical body (FIG. 6C), but the present invention is not limited thereto. Absent.
As shown in FIGS. 6A and 6B, a plurality of completely square base bodies 23 can be assembled as a pallet structure. A plurality of grooves 21 in the base body 23 of each square is arranged in a plurality of substantially cross shapes.
As shown in FIG. 6C, a plurality of completely cylindrical base bodies 23 can be assembled as a pallet structure. A plurality of grooves 21 in the base body 23 of each cylindrical body are arranged in a substantially U-shaped manner, an oblique groove 21 is added on the cross-shaped groove 21, and each inner surface in each groove 21 is also each A plurality of required insertion holes 22 are also provided so that when the cylindrical base body 23 collides with a forklift (or “pallet transporter”), the arc surface smoothly collides at a non-right angle. .
In addition, the rectangular base body 23 and the cylindrical base body 23 can be used in any combination. For example, as shown in FIG. 6D, a cylindrical base body 23 is provided at the center of a plurality of rectangular base bodies 23, and the square base body 23 in the center of FIG. 6A is replaced with a cylindrical base body 23. To do.

  In this embodiment, the inside of the base body 23 of the base 20 exhibits a hollow beam columnar structure 231. For example, in various shapes such as an H shape, an I shape, and an X shape, the supporting strength can be greatly increased while reducing the weight of the base. Next, the base body 23 has a first surface 23A and a second surface 23B that face each other, and a plurality of grooves 21 and a plurality of positioning insertion holes 22 are provided on the first surface 23A.
