Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of trolleys, in particular to a liftable trolley structure. Background Art
[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of handcarts is constantly developing, handcarts are still used as indispensable transport tools. Handcarts 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, and are very convenient for transporting lighter items over short distances. 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 handcarts (also known as tiger carts) for transporting pieced items, rack carts, and bucket carts for transporting bulk materials. A three-wheeled handcart has one, and a four-wheeled handcart has two swivel casters that can rotate around a vertical axis. Handcarts are divided into single-wheeled, two-wheeled, three-wheeled, and four-wheeled.
[0003] The common wheelbarrow structure is usually composed of a frame, wheels, a bucket and a handle. The bucket is installed on the top of the frame, the wheels are installed at the corresponding position of the bottom of the frame, and the handle is installed at the corresponding position of the front and rear ends of one side of the frame. When in use, the materials to be transported are placed on the bucket, and then the handle and wheels are used to move the materials to the destination. This is the common structure and use of the wheelbarrow. The traditional wheelbarrow structure has a simple structure and the structures are interconnected. It is widely used in the construction industry and can be used to transport building materials. In order to facilitate unloading, some of them tilt the wheelbarrow to the ground for unloading. However, during the tilting and falling process, the wheelbarrow will collide with the ground, resulting in partial damage to the wheelbarrow, overall vibration, loosening of the connection between the structures, and reducing the overall service life. Some wheelbarrow structures have a unloading port at the corresponding position of the wheelbarrow surface, so that the material can be unloaded from the unloading port. However, in this way, since some building materials (such as bricks, etc.) need to be stacked and stored, and a wheelbarrow usually unloads the building materials to the ground, it is not convenient to unload and stack the building materials that need to be stacked. Therefore, a liftable wheelbarrow structure is proposed. Utility Model Content
