Abstract

The invention discloses a folding type trolley, which comprises a rear frame, a first side frame, a second side frame, a bottom frame and at least a pair of door frames, wherein, the first side frame is fixed and connected on one side of the rear frame; the second side frame is movably connected to the other side of the rear frame; and the bottom frame is movably connected to the rear frame. The door frames comprises a first door frame and a second door frame, wherein, the first door frame is movably connected to the first side frame, and the second door frame is movably connected to the second side frame. The trolley of the invention is provided with door ends, thereby the safe transportation of goods is ensured. Simultaneously, the folding / opening of the trolley is convenient, the stacking is performed to save the storage space when the trolley has no load, and the structure of each connecting part is simple, thereby the overall intensity of the trolley is high.

Description

technical field [0001] The invention relates to a logistics appliance, in particular to a foldable trolley with a door end and a folding method thereof. Background technique [0002] As a convenient and practical modern logistics tool, the trolley has been widely used. Chinese patent ZL 92226553.4 discloses a retractable loading trolley 10, such as figure 1 As shown, the trolley includes a bottom surface 1 , a left elevation 2 , a right elevation 3 , and a rectangular frame 4 . A plurality of runners 5,6 can also be set below the trolley. When the trolley 10 is not in use, the bottom surface 1, the left facade 2 and the right facade 3 can be rotated to overlap with the rectangular frame 4 respectively, as figure 2 shown. Since the trolley 10 has only two facades, it is easy to cause the goods to fall after loading the goods, and is not suitable for loading goods in independent small packages; and it is also easy to cause the goods to be bumped and scratched by foreign o...
