Technical Field
[0001] The utility model belongs to the technical field of carts, and particularly relates to a cloth cover quick-disassembly structure of a cart. Background Art
[0002] A cart, also called a camper, camper or camping vehicle, is a transport vehicle that is pushed and pulled by manpower, making it convenient for users to transport items over short distances.
[0003] The frames of common carts are mostly made of metal rods with gaps formed between the metal rods. In order to prevent items from falling through the gaps, the frames are mostly provided with cloth covers. The cloth covers on common frames are detachably connected to the frames through connecting ropes. For example, a foldable shopping cart disclosed in Chinese utility model patent CN202222355182.7 includes a flat plate, wheels, a bracket, a shopping bag, a pull rod, and the like. Four steerable wheels are respectively installed at the four corners of the flat plate to form a flat four-wheel vehicle, 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 by a tether; a retractable pull rod is installed at one end of the shopping cart; the opening of the shopping bag adopts a zipper, that is, a square cover cloth is sewn on one side of the opening of the shopping bag, 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
