Description

Folding handcart

Technical Field

The utility model relates to a handcart field, concretely relates to folding handcart.

Background

The cart is a carrying vehicle which is pushed and pulled by manpower; the handcart can be divided into a single wheel, two wheels, three wheels and four wheels. The monocycle can run on a narrow gangway, an excrement bridge and a small sheep intestine road, can turn on site, and is very convenient to dump goods. Commonly used two-wheeled vehicles include hand trucks (aka tiger trucks) for handling articles, truck trucks, and hopper trucks for handling bulk materials. One of the three-wheeled hand trucks and two of the four-wheeled hand trucks are provided with swivel casters (see swivel casters). The swivel caster can automatically adjust to the direction with the minimum running resistance along with the change of the moving direction of the vehicle during running.

Carts for different purposes have different body configurations. The general four-wheel trolley is mostly provided with a cargo platform. The special handcart has various structures, and some handcart bodies are made into box shapes and are suitable for carrying light-weight articles which are convenient to load and unload; some vehicle bodies are completely matched with goods in shape, such as gas cylinder vehicles; some of the devices are very small and exquisite, can be folded and are convenient to carry; some truck bodies are provided with two flat steels to form a low inclined plane so as to facilitate loading and unloading of barreled liquid, paper rolls and other cylindrical goods, so that the cylindrical goods can roll up and down conveniently, such as a cylindrical goods loading and unloading truck. Modern trolleys are equipped with rolling bearings, solid or pneumatic tyres for the wheels.

The cart (Garden cart) is a manually pushed and pulled handling vehicle, which is the ancestor of all vehicles. Although the material handling technology of the trolley is continuously developed, the trolley is still used as an indispensable handling tool. The trolley is widely used in production and life because of its low cost, simple maintenance, convenient operation, light weight, ability to work in places where motor vehicles are not convenient to use, and convenience in carrying lighter objects in short distance.

In order to ensure the stability of the structure, the structure and the size of the traditional handcart are always fixed, so that the handcart is not only inconvenient to carry but also occupies a large space, and a large amount of space must be wasted due to the fact that the structure of the handcart is angled.
