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

[0021] Embodiment 1:

[0022] like Figure 1-4 As shown: it includes a U-shaped rod 1, a fixed storage tray 3 is provided at the bottom end of the U-shaped rod 1, a universal wheel 2 with a self-locking structure is fixedly installed on the bottom surface of the U-shaped rod 1, a movable storage tray 4 is provided above the fixed storage tray 3, and a movable ear plate 41 is fixedly installed at the bottom end of the front and rear side walls of the movable storage tray 4, and the movable ear plate 41 is movably sleeved on the outer surface of the U-shaped rod 1, both ends of the U-shaped rod 1 are provided with threads, and the outer surface of the U-shaped rod 1 is threadedly sleeved with a threaded sleeve 5, the threaded sleeve 5 is located below the movable ear plate 41 to support the movable ear plate 41, and the top surface of the threaded sleeve 5 is fixedly installed with an annular shock-absorbing pad 51, and the annular shock-absorbing pad 51 is made of rubber. The outer surface of the threaded sleeve 5 is provided with an anti-slip groove, and the height of the mobile storage tray 4 is adjusted by rotating the threaded sleeve 5. During the process of adjusting the height of the mobile storage tray 4, the movable ear plates 41 at both ends of one diagonal of the mobile storage tray 4 are always kept in contact with the threaded sleeve 5, and then the mobile storage tray 4 is always supported by the threaded sleeve 5, so as to avoid the mobile storage tray 4 from rising or falling suddenly. The mobile ear plates 41 can be cushioned by the annular shock-absorbing pad 51, so as to reduce the vibration of the mobile storage tray 4 and the medical supplies inside, and avoid the medical supplies on the top surface of the mobile storage tray 4 from being damaged or falling due to the vibration of the sudden drop of the mobile storage tray 4. The use is simple and convenient, which is conducive to the protection of medical supplies, and solves the problem that when the height of the storage plate is lowered in the existing device, the medical staff pulls out the screw rod from the card slot, which easily causes the storage plate to fall suddenly, and then causes the medical supplies on its top surface to be damaged or fall due to vibration;

[0023] Embodiment 2:

[0024] like Figure 1-4 As shown: evenly distributed hooks 42 are fixedly installed in the middle of the left and right side walls of the mobile storage tray 4, symmetrically distributed U-shaped plates 43 are fixedly installed on the left and right sides of the bottom surface of the mobile storage tray 4, ultraviolet lamps 44 are fixedly installed on the side walls of the U-shaped plates 43, and fixed ear plates 31 are fixedly installed at the bottom ends of the front and rear side walls of the fixed storage tray 3. The fixed ear plates 31 are fixedly sleeved on the bottom ends of the mobile ear plates 41. The hooks 42 are convenient for hanging work clothes and face shields of medical staff, and the ultraviolet lamps 44 are convenient for sterilizing and disinfecting work clothes and face shields of medical staff.

[0025] Working principle and use process of the utility model: when using the portable cart, medical supplies are placed on the fixed storage tray 3 and the mobile storage tray 4, and medical staff can hang work clothes and face shields on the hooks 42 on both sides of the mobile storage tray 4, and then turn on the ultraviolet light 44 to disinfect the work clothes and face shields. When the height of the mobile storage tray 4 needs to be lowered, the threaded sleeves 5 at both ends of the diagonal line of the mobile storage tray 4 can be rotated first to lower it to an appropriate height, and then the threaded sleeves 5 at both ends of the other diagonal line of the mobile storage tray 4 can be slowly rotated to move downward, and at this time, the mobile storage tray 4 will be on the threaded sleeves 5 at both ends of the diagonal line of the mobile storage tray 4. The movable ear plate 41 is supported by the sleeve 5 and moves downward until the bottom surface of the movable ear plate 41 contacts with the threaded sleeve 5 that has been moved downward first. When the height of the movable storage tray 4 needs to be increased, the threaded sleeves 5 at both ends of the diagonal of the movable storage tray 4 can be rotated first to lift it to an appropriate height. At this time, the movable ear plate 41 is always in contact with the top surface of the threaded sleeve 5. Then, the threaded sleeves 5 at both ends of the other diagonal of the movable storage tray 4 can be rotated until they contact with the bottom surface of the movable ear plate 41. The movable ear plate 41 can be cushioned by the annular cushioning pad 51, thereby reducing the vibration of the movable storage tray 4 and the medical supplies inside it.
