Description

Technical Field

[0001] The utility model relates to the technical field of carts, in particular to a novel small cart. Background Art

[0002] Oxygen tanks are commonly used medical equipment in hospital wards. Since liquid oxygen is stored in the tanks, oxygen tanks are usually made of metal and are very heavy, so medical staff usually use carts to transport oxygen tanks.

[0003] During transportation, medical staff only need to move the oxygen tank onto the cart and move the cart to the place where the oxygen tank needs to be placed.

[0004] For example, patent CN218021649U discloses a welding oxygen tank cart, comprising a rotating shaft, rollers rotatably arranged on both ends of the rotating shaft, a frame rotatably arranged on the rotating shaft, a rear support leg arranged below the frame at the rear side of the roller, the rear support leg comprising an upper leg body connected to the frame, a lower leg body arranged below the upper leg body, a wheel storage groove is provided on the bottom surface of the lower leg body, a guide slide hole and an upper positioning hole and a lower positioning hole located at both ends of the guide slide hole and distributed up and down are provided on the side wall of the lower leg body, a mounting frame with a universal wheel on the bottom surface is slidably arranged in the wheel storage groove, a guide slide column slidably matched with the guide slide hole is provided on the side wall of the mounting frame, a positioning sleeve is provided on the upper cover of the guide slide column and is plugged and matched with the upper positioning hole and the lower positioning hole to limit the movement of the mounting frame, and a groove for inserting the guide slide column is provided on the end surface of the positioning sleeve facing the guide slide column.

Secondly, the oxygen doses required by patients are different, which makes the diameters and heights of oxygen cylinders different, making it inconvenient to clamp oxygen cylinders of different volumes. For this reason, we designed a new type of cart to provide another technical solution to the above technical problems. Utility Model Content
