A layer board is arranged between the U-shaped grooves on the columns of two opposite bottom plates. The above solution has a simple assembly method and is convenient for disassembly, which is beneficial to transportation.

[0004] For the above solution, after removing the universal wheels at the bottom, it can be placed in the carriage for placing the goods in the carriage. However, although the above solution can select columns with different lengths for assembly according to the space limitation of the automobile carriage, the above solution needs to prepare a large number of types of columns to adapt to the heights of different carriages, which wastes resources. Content of the Utility Model

[0005] The utility model aims to provide a shelf for automobile transportation to solve the problem of resource waste existing in the above solution.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

Four telescopic rods are arranged between the bottom plate and the top plate. Each telescopic rod includes a rod sleeve and a sliding rod. The bottom of the rod sleeve is detachably connected to the bottom plate. A through groove is formed in the side wall of the rod sleeve and penetrates to its top. The sliding rod is slidably embedded in the groove, and the top of the sliding rod is detachably connected to the top plate. A plurality of first clamping grooves are arranged at intervals in the vertical direction on both sides of the groove of the rod sleeve. A plurality of second clamping grooves aligned with the first clamping grooves are arranged at intervals in the vertical direction on the side wall of the sliding rod. The grooves of the two telescopic rods located on the front and rear sides of the bottom plate face each other. Two groups of lifting mechanisms are symmetrically arranged on the left and right sides of the bottom plate for moving the top plate up and down. A plurality of layer boards are arranged at intervals in the vertical direction and are respectively detachably connected to the telescopic rods.

[0008] Principle and effect of the technical solution:
