Description

Technical Field

[0001] The utility model relates to the technical field of wheelbarrows, in particular to an industrial wheelbarrow with high stability. Background Art

[0002] A trolley is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of trolleys is constantly developing, trolleys are still used as indispensable transport tools. Trolleys are widely used in production and life because they are low-cost, simple to maintain, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use. They are very convenient for transporting lighter items over short distances. Trolleys are divided into single-wheeled, two-wheeled, three-wheeled, and four-wheeled. A wheelbarrow can travel on narrow springboards, temporary bridges, and goat paths. It can turn on the spot and is very convenient for dumping goods. Commonly used two-wheeled vehicles include hand-pushed transport trucks for transporting pieced items, rack trucks, and bucket trucks for transporting bulk materials. There is one swivel caster that can rotate around a vertical axis in a three-wheeled trolley and two swivel casters in a four-wheeled trolley. During operation, this swivel caster can automatically adjust to the direction with the least running resistance as the direction of vehicle movement changes.

[0003] The Chinese patent with the publication number CN220180803U discloses an industrial trolley with high stability, which includes: a storage table for placing items, the storage table is provided with a plurality of storage cavities, and a plurality of storage tubes are clamped in the storage cavities; a push handle connected to one side of the storage table; a leg connected to the bottom of the storage table, each of the legs is provided with a walking part and a limiting part, and the limiting part is used to fix each of the legs. The storage tube is limited by the limiting strips of each storage unit in the storage table to achieve stable placement of the storage tube; the height of the storage table, the storage cavity, the partition, and the storage tube is reduced in sequence, and the built-in items in the storage tube are blocked step by step to prevent them from escaping from the storage unit, effectively preventing the medical equipment from slipping. A limiting part is set on the leg to fix the four legs of the trolley and achieve the stability of the trolley. Even if the boat shakes, the medical equipment in the storage unit on it will not slide off the storage table, nor will they interfere with each other.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The prior art fixes the four legs of the trolley by setting a limiting component to achieve the stability of the trolley. However, the setting of the prior art device can only limit the position and maintain stability after the transportation is stopped. During the transportation of the trolley, there may be a situation where the road surface is uneven. The prior art device cannot remain stable in this situation, which will cause damage to the items stored inside. Utility Model Content
