[0002] Welded insulated gas cylinders are a special type of gas cylinders, mainly used to store liquefied natural gas, liquid oxygen, vehicle-mounted natural gas and cryogenic liquids, etc. It uses material composite technology to achieve thermal insulation, heat insulation or heat preservation performance between materials. This technology connects two materials with different thermal conductivity through inlay, coating or infusion, thereby reducing heat conduction. Its core principle is to isolate or reduce heat flow. Welded insulated gas cylinders use vacuum double-layer insulation. The sealed interlayer between the inner and outer containers is a vacuum insulation layer, which requires vacuumizing the interlayer of the welded insulated gas cylinder during production.

[0003] A Chinese patent discloses a welded insulated gas cylinder interlayer vacuum pumping device (authorization announcement number CN220669172U). This patented technology improves the moving mechanism so that the motor inside the box controls the rotation of the shaft, making it easier for the user to control the lifting and lowering of the moving mechanism. When movement is not required, the motor is driven to rotate the shaft in the opposite direction, and the universal wheels are stored in the box, so that the device can be supported by the bottom of the box, with a larger contact area and more stable placement.

[0004] However, there are still some shortcomings in this patent. Although the patent can store the universal wheel, it can be seen from the drawings of the patent that the patent requires multiple structures such as motors and rotating shafts to cooperate with each other to store the universal wheel.
