Description

Technical Field

[0001] The utility model relates to the technical field of cargo binding devices, in particular to a cargo binding device for a trolley. Background Art

[0002] A trolley is a piece of equipment used for short-distance, small-volume transport of goods. The trolley includes a shelf. The shelf of the trolley refers to a structure that provides certain support or lifting functions to the goods during the cargo transfer process. A trolley is a transport vehicle that is pushed and pulled by manpower. There are one-wheeled, two-wheeled, three-wheeled and four-wheeled trolleys. The one-wheeled trolley can travel on narrow springboards, temporary bridges and goat paths, can turn on the spot, and is very convenient for unloading goods. Two-wheeled vehicles include hand-pushed transporters (also known as tiger carts) for transporting piece items, rack carts and bucket carts for transporting bulk materials.

[0003] Existing commonly used trolleys usually transport goods of regular shapes. However, if the goods are irregular, they are prone to tipping over when encountering a sloped road surface. The stability of use is poor, and elastic rope hooks are generally used to tie the goods when fixing them. It is easy to cause accidental injuries during use, and the elastic ropes used are not easy to store, which is very inconvenient. Therefore, technical personnel in this field provide a trolley cargo tie-down device to solve the problems raised in the above background technology. Utility Model Content
