Description

Technical Field

[0001] The utility model belongs to the technical field of carts, and in particular relates to a cloth bag installation structure for a cart. Background Art

[0002] A trolley, also called a shopping cart, is a transport vehicle that is pushed and pulled by manpower, making it convenient for users to transport items over short distances.

[0003] Most common carts are provided with cloth bags on their frames, and the cloth bags on the common frames are detachably connected to the frames through connecting ropes, such as a foldable shopping cart disclosed in Chinese utility model patent CN202222355182.7, which includes a flat plate, wheels, brackets, shopping bags and pull rods, etc. Four steerable wheels are respectively installed at the four corners of the flat plate to form a flat plate four-wheeled cart, and a U-shaped bracket is installed at each end of the flat plate through a bracket seat. Since the bracket seat adopts a U-shaped groove structure with one end closed, the two brackets are restricted by the closed end of the bracket seat and can only rotate 90 degrees toward the flat plate, thereby forming a foldable structure facing the flat plate; a shopping bag is installed between the two U-shaped brackets, and the shopping bag is fixed to the flat plate and the bracket through a tether; a retractable pull rod is installed at one end of the shopping cart; the opening and closing method of the shopping bag mouth adopts a zipper, that is, a square cover cloth is sewn on one side of the shopping bag mouth, and zippers are sewn on the other three sides of the shopping bag and the cover cloth accordingly.

[0004] In the above structure, the shopping bag is installed on the bracket by a tether. During the installation process, the tether needs to be disassembled or connected to the bracket one by one, which is not convenient for quick installation and disassembly. The tether is easy to loosen after long-term use. In order to reduce the relative movement between the tether and the bracket, a rope hole corresponding to the tether is provided on the bracket. However, the rope hole will wear the tether during use, thereby causing the tether to break, affecting the use of the shopping cart. Summary of the invention
