a medical trolley

Abstract

The invention belongs to the technical field of trolleys, and in particular relates to a medical trolley, which includes a base, a push rod, a front wheel, a steering mechanism and a rear wheel. The walking mechanism of the trolley adopts four traditional walking wheels without automatic steering function , the cart adjusts the swing of the front wheels through the steering mechanism during the steering process, and the cart is driven by the swing of the front wheels to realize the steering function. The only cart that uses universal wheels to realize the steering is the front wheel or the rear wheel; the external force required for the steering of the cart is relatively small; and compared with the carts used in the traditional medical field, the cart is more It can pull and transport some medical heavy objects, and it is more convenient and labor-saving than traditional medical carts with universal wheels.

Description

[0001] Technical field [0002] The invention belongs to the technical field of trolleys, in particular to a medical trolley. Background technique [0003] At present, in hospitals, medical personnel often need to move a lot of medical appliances and medical appliances to places where they are needed during their work. In order to facilitate the transfer of these medical appliances, trolleys are usually used. [0004] Generally, the carts used in medical treatment have four universal wheels that are convenient to the steering of the carts, but when the carts with four universal wheels turn when carrying heavy items, the inertia is also high due to the large weight they carry. Larger, and the steering is completely driven by manpower, so this operation is very inconvenient; then for this kind of cart that pulls heavy objects, in order to realize the steering of the cart in motion with less effort, this kind of cart generally uses Front-wheel steering or rear-wheel steering ins...

Problems solved by technology

[0004] Generally, the carts used in medical treatment have four universal wheels that are convenient to the steering of the carts, but when the carts with four universal wheels turn when carrying heavy items, the inertia is also high due to the large weight they carry. Larger, and the steering is completely driven by manpower, so this operation is very inconvenient; then for this kind of cart that pulls heavy objects, in order to realize the steering of the cart in motion with less effort, this kind of cart generally uses Front-wheel steering or rear-wheel steering instead of traditional four-wheel steering; the current cart uses universal wheels to achieve front-wheel steering or rear-wheel steering; When the cart is on a road with a slope, a large force is required to turn the cart. At the same time, if it is parked on a slope, because the front or rear wheels are universal wheels, the universal wheels are on the slope. Automatic steering, the cart cannot be completely still on a sloped road, so it is necessary to design a cart that can pull heavy objects on a sloped road and can be easily turned or parked when driving
