[0002] Since valuable items such as furniture and electrical appliances, such as washing machines and refrigerators, generally have fixed feet at the bottom for fixed placement and are not movable, during daily handling, a bracket with pulleys needs to be installed at the bottom, and the pulleys are used for movement. After moving to the destination, the bracket needs to be removed, and the furniture and electrical appliances are supported on the ground by their own feet for stable placement.
[0003] Existing brackets are generally fixed frames, which are fixed by welding multiple groups of steel rods, and pulleys are connected at the four corners of the bottom. This kind of fixed frame is generally designed independently according to the sizes of different furniture and electrical appliances, and it is difficult to adapt to furniture and electrical appliances of different sizes. Moreover, this kind of frame is only installed and used when moving is needed. When placing furniture and electrical appliances daily, the frame needs to be removed to avoid affecting the stability of furniture and electrical appliances. Disassembly and installation are rather troublesome. Therefore, the utility model proposes a retractable lifting handling mechanism with casters to solve the problems existing in the prior art.

At the same time, the rubber foot pad 10 at the bottom is used to touch the ground. The vibration generated when the home appliance is working is partially eliminated by the top rubber pad 9, and then eliminated by the bottom rubber pad 10, so that the home appliance can be increased and shock-absorbed. The product is provided with a caster 13 at the bottom. By pulling the wrench 21 and utilizing the sliding of the fifth bolt 20 and the rotational connection of the sixth bolt 23 and the telescopic guide rail 2, the second lifting guide rail 4 and the telescopic guide rail 2 are driven to slide and stagger, and the first lifting guide rail 3 and the upper cover 1 are driven to slide and stagger by the same distance simultaneously, so that the L-shaped groove 14 moves to squeeze the rivet 12, so that the rivet 12 moves and rises in the Z-shaped groove 11, and the caster 13 can move up and down. When the caster 13 is at the bottom of the track and touches the ground, it can be moved by pushing the caster 13. When the caster 13 is reset and the rubber foot pad 10 touches the ground, it can be stably placed without frequent disassembly, adapting to different application scenarios and switching, and easy to use.
