A plurality of columns 2 are fixed to the back surface of the top plate 1, and the columns 2 are spaced apart from each other.

Because the back of the plate body 11 is provided with a plurality of mounting grooves 111, each reinforcing rod 12 is embedded in each groove, and meanwhile, each reinforcing rod 12 is partially pressed between the plurality of upright posts 2 and the plate body 11 respectively. Therefore, when each of the pillars 2 is fixed to the plate body 11, each of the reinforcing rods 12 can be fixed to the plate body 11. Because each reinforcing rod 12 is arranged in parallel to the plate body 11, one end of each reinforcing rod 12 hardly penetrates through the upper surface of the plate body 11 and is exposed from the upper surface of the plate body 11, so that the practicability of the pallet can be enhanced.

In addition, preferably, the installation grooves are not crossed with each other, and because the installation grooves 111 are not crossed with each other, the steel pipes 3 are not overlapped with each other in the installation process of the steel pipes 3, so that the tray is prevented from being too heavy due to the fact that the top plate 1 is too thick.

Further, both ends of each reinforcing bar 12 in the longitudinal direction are pressed between each upright 2 and the plate body 11.

Specifically, as shown in fig. 4 and 5, in order to enhance the strength of the top plate 1, the top plate 1 further includes a plurality of cross bars 13, each cross bar 13 is inserted into the plate body 11 in a direction parallel to the plate body 11, and each reinforcing bar 12 and each cross bar 13 are not arranged to intersect on the plate body 11.

Further, it is preferable that both ends in the longitudinal direction of each reinforcing bar 12 are pressed between each upright 2 and the plate body 11 as shown in fig. 3, 5 and 6, and 8 and 9, but of course, in some embodiments, each reinforcing bar 12 may be pressed between the upright 2 and the plate body 11 at the bar middle portion.

As shown in fig. 4 and 5, the cross members 13 are arranged in parallel in the longitudinal direction of the top plate 1. As shown in fig. 3, the columns 2 are divided into a plurality of rows, the columns 2 in each row of columns 2 are spaced from each other along the length direction of the pallet, and the columns 2 in each row are spaced from each other along the width direction of the pallet.

As shown in fig. 2 and 3, the columns 2 are three rows, and each row of columns 2 has three columns 2. Of course, in some embodiments, the columns 2 may also be four rows or five rows, and each row of columns 2 may also be four or five, and in any case, without departing from the scope of the present invention.

In addition, a plurality of beam rods 13 are respectively provided along the rows of columns 2. As shown in fig. 2 and 3, the columns 2 are arranged in three rows, the beam rods 13 are six, and every two beam rods 13 are arranged along one row of columns 2 and penetrate through the row of columns 2. Of course, in some embodiments, there may be three beam rods 13, and each beam rod 13 is disposed along one row of the columns 2, and of course, the beam rods 13 may be disposed in other manners besides the manner described above, as long as the present invention does not depart from the scope of the present invention.

As shown in fig. 5 and 6, and fig. 8 and 9, some of the reinforcing bars 12 are first bars 121, and some of the reinforcing bars 12 are second bars 122, wherein the first bars 121 are disposed parallel to each other and perpendicular to the cross bars 13, and the second bars 122 are disposed to intersect with the reinforcing bars 12.

Specifically, as shown in fig. 5 and 8, the first bars 121 are arranged along the width direction of the top plate 1, and the second bars 122 are arranged obliquely with respect to the cross bars 13. Preferably, each second rod 122 is disposed avoiding the upright 2 at the top corner of the plate body 11. With this arrangement, the strength of the plate body 11 can be enhanced by the respective reinforcing plates.

After the reinforcing rods 12 and the beam rods 13 are arranged in the above manner, the strength of the top plate 1 can be improved to the maximum extent on the basis of not increasing the thickness of the top plate 1 and not puncturing a packaging bag, so that the upper surface of the top plate 1 is a plane, and the reinforcing rods 12 and the beam rods 13 are arranged at all positions of the top plate 1 for reinforcing.

In addition, the plate body 11 is a plastic piece, the plate body 11 is connected with the upright post 2 through hot melting welding, the body of the upright post 2 is also a plastic piece, and the steel pipe 3 is arranged in the upright post 2 for reinforcement. Of course, in some embodiments, the plate body 11 and the upright 2 may be made of other materials such as wood, without departing from the scope of the present invention.

In practice, therefore, the anti-skid members 5 can be individually manufactured as a finished product, which is then welded to the tray body. Since the material of the base plate 51 is the same as that of the back surface of the disc body, the base plate 51 can be firmly welded to the back surface of the disc body, and the durability of the nonslip 5 can be improved.

Optionally, the periphery of the anti-slip plate 52 is embedded in the base plate 51, and the central region of the anti-slip plate 52 protrudes out of the base plate 51. Because the anti-skid plate 52 is embedded in the base plate 51, the connection between the anti-skid plate 52 and the base plate 51 is firmer. Since the central region of the anti-skid plate 52 protrudes out of the base plate 51, the base plate 51 does not interfere with the normal operation of the anti-skid plate 52.

In addition, in this embodiment, the back surface of the disc body and the base plate 51 are made of plastic, and the base plate 51 and the anti-slip plate 52 are connected by way of encapsulation. The substrate 51 is soldered to the rear surface of the tray body by thermal welding.
