  In addition, the inside of each central seat 10, each main seat 20, and each side seat 60 can be hollow to reduce the weight of the entire assembly-type pallet 1 and save costs.

  Accordingly, the assembly type pallet 1 of the present invention easily adjusts the angle of the diagonal connecting rod 40 using the structural design of the main diagonal groove portion 23 and the central diagonal groove portion 12, and the assembly type pallet 1 Can be adjusted to different sizes. This will be further described below in combination with the drawings.

As shown in FIG. 5, in this embodiment, the overall length L1 of the assembly-type pallet 1 (that is, the distance between the two main seats 20 in the vertical direction opposite to each other) and the overall width L2 (that is, in the lateral direction). For example, the total length L1 and the total width L2 of the assembly-type pallet 1 are 1100 cm, and the two connecting rods adjacent to the diagonal connecting rod 40 are the same. The included angle θ1 between 30 is 45 degrees, the included angle θ2 is 90 degrees, and the included angle θ3 is 45 degrees. At this time, both ends of the diagonal connecting rod 40 can be held by the main holding portion 25 and the central holding portion 14 respectively.
As shown in FIGS. 6, 7B and 8, the overall length L1 ′ of the pallet (that is, the distance between the two main seats 20 in the vertical direction facing each other) is 1000 cm, and the overall width L2 ′ (that is, the lateral width). When the distance between the two main seats 20 in the direction is 1200 cm, the included angle θ1 ′ between the diagonal connecting rod 40 and the two adjacent connecting rods 30 is 52 degrees, and the included angle θ2 Is 90 degrees and the included angle θ3 ′ is 38 degrees. At this time, the entire assembly-type pallet 1 in FIG. 5 and its included angles θ1 and θ3 are different from the entire assembly-type pallet 1 and its included angles θ1 ′ and θ3 ′ in FIG. Both ends of the angular connecting rod 40 can be sandwiched between the main holding part 25 and the central holding part 14, respectively. That is, even after changing the angle of one end of the diagonal connecting rod 40 using the central outer extending portion 13 and the central inner extending portion 15, it can be held by the central holding portion 14. The other end can also be clamped by the main holding portion 25 after changing the angle in the main external extension portion 24 and the main internal extension portion 26.

The assembly-type pallet 1 described above has the included angles θ1 and θ1 ′ of 45 degrees and 52 degrees according to different sizes, but in another embodiment, the overall length (L1 and L1 ′ respectively) and the overall width ( L2 and L2 ′), respectively, can also be varied based on actual usage needs. For example, when the overall length is 1100 cm and the overall width is 1200 cm, the included angle θ1 between the diagonal connecting rod 40 and the two connecting rods 30 adjacent to each other is 48 degrees, the included angle θ2 is 90 degrees, and the included angle θ3. Is 42 degrees. Alternatively, when the overall length is 1000 cm and the overall width is 1100 cm, the included angle θ1 between the two connecting rods 30 adjacent to the diagonal connecting rod 40 is 49 degrees, the included angle θ2 is 90 degrees, The included angle θ3 is 41 degrees.
After changing to the assembly-type pallet 1 having the different size, the 48 degrees and 49 degrees of θ1 are both between 45 degrees and 52 degrees, and both ends of the diagonal connecting rod 40 are connected to the main holding portion 25. And both ends of the diagonal connecting rod 40 in the central outer extension 13, the central inner extension 15, the main outer extension 24, and the main inner extension 26, respectively. By changing the angle to a necessary angle, it is possible to achieve the operation of sharing the clamping angle between the diagonal groove portion 23 and the central diagonal groove portion 12.

  Further, as shown in FIG. 7B, the diagonal connecting rod 40 has a rod end portion 401 located in the main inner extension portion 26 with the main holding portion 25 as a dividing point, and a rod intermediate portion located in the main outer extension portion 24. 402 can be classified. The diagonal connecting rod 40 is swung with a portion held by the main holding portion 25 as a fulcrum, and the rod end portion 401 is swung in the main internal extension portion 26 to adjust the angle, and the rod intermediate portion 402 is moved to the rod. The projection distance from the end of the inner arc surface 261 and the end of the outer arc surface 241 located on the same side to the corresponding diagonal connecting rod 40 is inversely proportional. By constructing and changing the diagonal connecting rod 40 to the required angle, different sizes of the assembled pallet 1 can be formed.

In addition, as shown in FIGS. 7A and 7B, in this embodiment, the distance between the two outer arc surfaces 241 is larger than the distance between the two inner arc surfaces 261, and the end of the diagonal connecting rod 40. When the portion is changed to the required angle by the main internal extension 26, the end of the diagonal connecting rod 40 is held by the holding surface 251 of the main holding portion 25, and is further brought into contact with the inner arc surface 261, The holding area of the end portion of the diagonal connecting rod 40 can be increased, and the positioning strength can be increased.
In some embodiments, each outer arc surface 241 has the same curvature as each inner arc surface 261 (that is, the outer arc surface 241 and the inner arc surface 261 have the same curvature arc, similar to the form of the central diagonal groove portion 12. After adjusting the angle of the diagonal connecting rod 40, it is held on the holding surface 251 of the main holding portion 25, and is also abutted on the average by the outer arc surface 241 and the inner arc surface 261 for positioning. Strength can be increased.

In summary, the diagonal connecting rod can be adjusted to different angles through the design of the main diagonal groove portion and the central diagonal groove portion, and the main seat body and the central seat body can have different lengths. The distance between the main seat and the central seat can be adjusted by fixing the size of the assembly-type pallet in two directions, the horizontal direction and the vertical direction. You can freely combine and change them according to your needs.
For this reason, if the main seat or the central seat is damaged due to an impact on any size assemble pallet, replacing it with a new main seat or the central seat eliminates the need to discard the entire body, greatly increasing costs. And the usage rate of the assembly-type pallet can be increased.
