Description

Foldable three-side trolley convenient to use Technical Field The utility model relates to the technical field of trolleys, in particular to a foldable three-side trolley convenient to use. Background A trolley is an apparatus for carrying and handling goods inside a warehouse or a logistics center, and is generally provided with a partition to divide the trolley to include at least two holding spaces so that different types of goods can be separately placed. The three-sided trolley is used for bearing the weight of the products stacked at the bottom through the two side pieces on the structure of the three-sided trolley on the market, deformation and other conditions can occur easily in the outer frame tube of the side pieces, when the existing products are folded, the folding position is usually determined by folding one side of the side pieces, and the other side is fixed, so that the occupied space is relatively large, the stability is poor, and the assembly of the three-sided trolley is inconvenient. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a foldable three-sided trolley convenient to use, which solves the problems that the existing three-sided trolley on the market in the prior art is relatively large in occupied space and poor in stability, and the existing product is inconvenient to assemble due to the fact that the two side pieces are used for bearing the weight of a product stacked at the bottom on the structure of the three-sided trolley on the market, deformation and the like of the outer frame tube of the side piece are easy to occur, and when the existing product is folded, the folding position is usually determined by folding one side of the side piece and fixing the other side of the side piece. The foldable three-sided trolley is characterized in that angle irons are fixedly welded in the underframe, a bottom plate is arranged on the underframe, locks are arranged at the bottom position of the bottom plate, first guard rails are arranged at the rear end of the underframe, caster plates are fixedly arranged at the two sides of the bottom of the first guard rails, connecting grooves are fixedly arranged on the inner end surfaces of the caster plates, first universal wheels are fixedly arranged at the bottom positions of the caster plates, braking plates are arranged in the first universal wheels, two connecting plates are fixedly arranged at the bottom positions of the first guard rails, second universal wheels are fixedly arranged at the two sides of the bottom of the underframe, and braking plates are arranged in the second universal wheels.
