Description

Shallow

Technical Field

The utility model relates to a commodity circulation transportation field, more specifically say, relate to a shallow.

Background

The handcart is a carrying vehicle which is pushed and pulled by manpower, is the ancestor of all vehicles, and is widely applied in production and life because of low manufacturing cost, simple maintenance, convenient operation and light dead weight, can work in places where motor vehicles are inconvenient to use, is very convenient to carry lighter objects at short distance, and is applied to the field of logistics transportation as an indispensable carrying tool;

the cart is generally a flat-plate cart and a shelf cart respectively according to application forms;

the flat plate type cart is shown in Chinese patent with publication number CN214985509U, and discloses a cart, and the device strengthens the strength of the handrail by arranging structures such as a bottom plate, handrails, trundles, torsion springs, folding cross bars, rotating shafts, handrails, a first beam, a second beam, a third beam, a fourth beam and the like, improves the stability of the bottom plate, increases the load capacity and the service life of the bottom plate, can be applied to various goods with larger sizes or larger weights, and has better stability;

however, when the goods with different sizes and different weights are transported, a plurality of goods are usually stacked together and are disordered, and when the goods positioned in the center are taken, the goods at the outer side need to be taken out to complete the operation, so that the operation convenience is poor;

the goods shelf type trolley is shown in Chinese patent with publication number CN206406948U, and discloses a logistics trolley, the device is simple to use and operate, goods do not need to be classified during logistics transportation, the conveying speed and the working efficiency are improved, shock caused by collision can be reduced during transportation, the safety of the goods is protected, and the goods with different sizes and different weights can be conveniently transported;

but the bearing capacity is poor, the storage space is small, and the stability is poor when goods with larger size or larger weight are transported;

in summary, the existing cart cannot have the convenience of transporting goods with different sizes and different weights and the stability of transporting goods with larger sizes or larger weights, and cannot have the advantages of a shelf cart and a flat-bed cart at the same time, so that a good transporting effect cannot be kept in the transporting process of various goods, and therefore the cart is provided.
