[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] See also Figure 1 、 Figure 2 and Figure 4 , an embodiment provided by the utility model:

[0023] An adjustable cargo pallet comprises: a pallet 1, with connecting plates 2 installed at the four corners of the top of the pallet 1, damping shafts 3 extending through both sides of the connecting plate 2, and expansion plates 4 connected to both sides of the connecting plate 2 via the damping shafts 3. Positioning slots 5 are provided on both sides of the top of the connecting plate 2, and limiting plates 6 are installed on both sides of the expansion plate 4, wherein the sizes of the positioning slots 5 and the limiting plates 6 are adapted to each other.

[0024] The setting of the connecting plate 2 can play a good supporting and connecting role. The combination of the damping shaft 3 and the expansion plate 4, when the area of the pallet 1 itself is sufficient to place the transported items, there is no need to place the expansion plate 4 flat, and due to the blocking function of the damping shaft 3 itself, the expansion plate 4 can be kept vertical to the pallet 1, and can also play a certain limiting role for the transported items. The combination of the expansion plate 4, the positioning groove 5 and the limiting piece 6, when the area of the pallet 1 itself is not enough to place the transported items, the staff can lay the expansion plate 4 flat, and the limiting pieces 6 on both sides of the expansion plate 4 will contact the positioning groove 5 opened on the top of the connecting plate 2, thereby playing a limiting and positioning role and expanding the use area of the pallet 1. The overall structure of the device is simple, and without significantly increasing the manufacturing cost, it also improves the functionality of the device, so that the pallet 1 has better adjustability.

[0025] Example 2:

[0026] See also Figure 1 and Figure 3 , an embodiment provided by the utility model:

[0027] Furthermore, a fixed sleeve 7 is installed on the top of the connecting plate 2, and a limited sliding groove 8 is provided on the top of the fixed sleeve 7;

[0028] The setting of the fixed sleeve 7 can play a better supporting and connecting role. The setting of the limiting slide groove 8 and the irregular shape of the insertion port can facilitate the staff to quickly connect and align it.

[0029] Furthermore, a movable rod 9 is slidably connected to the interior of the limiting slide groove 8, and the movable rod 9 is installed at the bottom of the connecting plate 2 and is positioned horizontally with the fixed sleeve 7;

[0030] The movable rod 9 and the fixed sleeve 7 are used in combination. The movable rod 9 and the fixed sleeve 7 are respectively located at the bottom and the top of the connecting plate 2, so that when actually working, it is convenient for workers to align and stack multiple pallets 1, thereby improving transportation efficiency.

[0031] Furthermore, the surfaces of the movable rod 9 and the fixed sleeve 7 are both provided with a plurality of limiting holes 10, and the positions thereof are relatively horizontal;

[0032] Furthermore, a positioning pin 11 is connected through the interior of the limiting socket 10, and the size of the positioning pin 11 is adapted to the limiting socket 10;

[0033] The limited socket 10 and the positioning pin 11 work together. After the staff places the transported items on the pallet 1, they can control the depth of the movable rod 9 inserted into the fixed sleeve 7 according to the height of the transported items. When the distance is adjusted to an appropriate level, the positioning pin 11 is inserted into the limited socket 10 to complete the limited support. This allows the structure to adjust to transported items of different heights, avoiding damage to the transported items placed in the pallet 1 when the pallets 1 are stacked for transportation.

[0034] Furthermore, a placement groove is provided on the top of the tray 1, and anti-slip grooves 12 are provided inside the placement groove;

[0035] The provision of the anti-slip grooves 12 can increase the friction between the pallet 1 and the transported items, thereby preventing the transported items from falling and causing damage as much as possible.

[0036] Working principle:

[0037] The staff can first decide whether to expand the plate 4 below according to the number or area of the transported items. When the expansion plate 4 is laid flat and used with the pallet 1, the overall placement area can be increased. When the expansion plate 4 is folded, it can also provide a certain limiting effect. At the same time, if the pallet 1 needs to be stacked for transportation, the staff can also adjust the insertion distance between the fixed sleeve 7 and the movable rod 9 according to the height of the transported items, so that the pallet 1 will not be pressed down by the upper pallet 1 during the stacking and transportation process and cause damage.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
