[0035] The working principle of a tray with expansion function provided by the utility model is as follows:

[0036] Step 1: When the tray needs to be expanded during use, the insertion rod 11 is pulled upwards through the pull ring 13, so that the limit ring 10 drives the spring 12 to contract upwards, thereby canceling the limit of the tray plate 7, and then the two tray plates 7 are pulled to the separated side through the pull plate 15, and then the two tray plates 7 are separated to form the space required for the expansion plate 25 in the middle. After adjustment, the pull ring 13 is released and the position of the tray plate 7 is fixed again using the insertion rod 11;

[0037] Step 2: Rotate the rotating sleeve 22 through the rotating rod 26, and the rotation of the rotating sleeve 22 drives the screw rod 23 to move upward in the installation sleeve 21. The movement of the screw rod 23 drives the connecting plate 24 and the expansion plate 25 to move upward, so that the expansion plate 25 is adjusted to the same height as the pallet plate 7. After adjustment, the threaded sleeve 4 is rotated upward on the threaded rod 3, thereby driving the support ring 5 to limit the position of the expansion plate 25, thereby improving the stability of the expansion plate 25 when in use.

[0038] Compared with the related art, the tray with expansion function provided by the utility model has the following advantages:

[0039] Beneficial effects:

[0040] The screw rod 23 is driven to move upward by rotating the rotating sleeve 22, and the movement of the screw rod 23 drives the connecting plate 24 and the expansion plate 25 to move upward, so that the expansion plate 25 is adjusted to a height consistent with the pallet plate 7. After adjustment, the position of the expansion plate 25 is limited by the threaded sleeve 4 and the supporting ring 5. The operation is simple and convenient, and it is very convenient to expand the pallet, thereby increasing the load capacity of the pallet. The expansion will not affect the stacking of the goods, and the problem of collapse due to height difference after stacking can be avoided.
