Novel trolley

Abstract

The novel trolley comprises a foldable trolley frame, a pushing handle and four roller assemblies, the pushing handle is installed on the rear portion of the trolley frame, the four roller assemblies are installed at the four corners of the trolley frame, the trolley frame comprises a frame body and a bottom frame assembly, the frame body is composed of a front wall assembly, a rear wall assembly and two side wall assemblies, the bottom frame assembly is located at the bottom of the frame body, and each side wall assembly comprises two connecting rods. Each group of connecting rods comprises long rods, a middle rod and a short rod, the lower end parts of the two long rods are rotationally connected to form a V shape with an upward opening, the upper end parts of the two long rods are rotationally connected with the upper end parts of the front wall assembly and the rear wall assembly respectively, and the upper end part of one middle rod is rotationally connected with the upper end part of one short rod to form a V shape with a downward opening; the lower end parts of the two middle rods are rotationally connected with the lower end parts of the front wall assembly and the rear wall assembly respectively, the upper sections of the two middle rods are riveted with the upper sections of the two long rods respectively, and the lower end parts of the two short rods are riveted with the lower sections of the two long rods respectively. The cart can be folded and stored, the structure is novel, the cloth bag and the frame of the cart are convenient and fast to disassemble and use.

Description

technical field [0001] The invention belongs to the technical field of trolleys, and in particular relates to a novel trolley. Background technique [0002] Because of its simple operation, convenient use and strong passability, it can be used in various complex environments, and the trolley can be popularized in life and production. As an important part of the trolley, the frame often determines the performance of the trolley. However, the traditional trolley frame is complex in structure, large in size, not very convenient, and often cannot be disassembled and folded, which is not conducive to transportation in various environments. Materials are not conducive to folding and storage before and after use, and it also increases the difficulty of carrying and using. The storage platform of the traditional trolley rack cannot be disassembled or the installation is not firm enough, and it is easy to drop or cause damage to the items during use. Therefore need to improve hand ...
