Foldable station running vehicle structure and folding and unfolding method

Abstract

The invention provides a foldable station running vehicle structure and a folding and unfolding method, and belongs to the field of station tools. The problem that an existing running vehicle cannot be folded is solved. The running vehicle structure comprises an upper frame plate and a lower frame plate in which upper rod holes and lower rod holes are formed, and further comprises frame rods and supporting rods, the bottom ends of the frame rods penetrate through the lower rod holes and fixed with casters, the top ends of the frame rods penetrate through the upper rod holes and are hinged to the bottom ends of the supporting rods, handrail rods and upper connecting rods which are connected with the supporting rods are further included, baffle rings and baffle strips are fixed on the framerods, inner locking grooves are formed in the rod walls of the supporting rods, blocking grooves are formed in the hole walls of the lower rod holes, inner sleeves which sleeve the supporting rods andouter sleeves which sleeve the inner sleeves are further included, baffles fixed to the top surface of the upper frame plate are fixed on the top ends of the inner sleeves, the outer sleeves are embedded in the upper rod holes, locking holes in the inner sleeves and locking beads in the locking holes are further included, outer locking grooves are formed in the inner walls of the outer sleeves, the outer walls of the inner sleeves and the inner walls of the outer sleeves are provided with sliding grooves and slip rings, and compression springs which sleeve the sliding grooves are further included. The running car structure can be flexibly folded.

Description

technical field [0001] The invention belongs to the technical field of station appliances, and relates to a foldable station operating car structure and a folding and unfolding method. Background technique [0002] Station equipment is a variety of devices used by enterprises to store production objects or tools in the production site or warehouse. It is used to hold various parts, raw materials, etc., to meet production needs, and to facilitate the operation of production workers. The auxiliary equipment used is indispensable in every link of the production process. The commonly used station equipment in the assembly line mainly includes: workbenches, tool cabinets, tool carts, lockers, parts storage racks, sub-packaging stands, material boxes, hoppers, collection boxes, operating vehicles, etc. [0003] Existing trolleys generally have an overall fixed structure, which cannot be folded and stored, resulting in occupying space when not in use, and not flexible enough, so i...
