The technical solution of the utility model is achieved in that a kind of folding dining car, comprise supporting plate, leg and castor, leg comprises front-seat leg and back row's leg, supporting plate comprises mounting plate, the middle supporting plate and the bottom plate that are spliced by the two blocks of supporting plates in front and back, be provided with folding device between front-seat leg and the back row's leg, folding device comprises the movable brace rod that is set in parallel between front-seat leg and the back row's leg, two ends be movably hinged with movable brace rod and front support leg or rear leg respectively and be used for installing supporting plate and bottom plate two on lateral frame and twice lateral frames, be slidably disposed on the traction sliding sleeve on movable brace rod top, be fixedly installed on the locking piece and two draw bars on movable brace rod top, the two ends of draw bar are connected with the bottom of traction sliding sleeve and front-seat leg or back row's leg respectively, are movably hinged by articulated jib between mounting plate and front-seat leg or the back row's leg.
Wherein, above-mentioned articulated jib comprises the two metal elongate body that are arranged on the mounting plate both sides, and an end and the mounting plate of articulated jib are movably hinged, and the other end and front-seat leg or back row's leg are movably hinged.
Open the back Stability Analysis of Structures for guaranteeing dining car, locking piece comprise fixedly be nested with at the fixed cover on the movable brace rod, be articulated in the elastic locking piece on the fixed cover swingably and be arranged on fixed cover and elastic locking piece between back-moving spring, inboard, elastic locking piece lower end is provided with and draws the suitable draw-in groove that closes of projection that the sliding sleeve upper end outside is provided with.The fixed cover both sides are provided with driving rod, elastic locking piece is a square slotted vane, elastic locking piece is articulated on the driving rod by its both sides slotted vane swingably, be provided with projection at the bottom of the square groove of corresponding elastic locking piece on the fixed cover, one end of back-moving spring is nested with on projection, and is inconsistent at the bottom of the other end of back-moving spring and the square groove of elastic locking piece.
In the time will folding dining car, earlier mounting plate is rotated a side that stands in front-seat leg or back row's leg around articulated jib, stir the shifting block that the elastic locking piece upper outside of dining car both sides is provided with then respectively, inboard, elastic locking piece lower end draw-in groove that is provided with and the projection that the outside, traction sliding sleeve upper end is provided with are separated, the power of borrowing is then up carried movable brace rod, makes front support leg down draw into folded state in rear leg simultaneously; In the time will opening dining car, movable brace rod is moved down, under the promotion of two connecting rods, the traction sliding sleeve slides near fixed cover, and stir the shifting block that the elastic locking piece upper outside of both sides is provided with respectively with two hands this moment again, and the projection that is provided with outside making on draw-in groove that inboard, elastic locking piece lower end is provided with and the traction sliding sleeve is buckle mutually, unclamp behind the hand under the effect of back-moving spring restoring force, the elastic locking piece traction sliding sleeve that links closely, thus it is loosening to prevent to draw sliding sleeve, opens the stability of back when using to guarantee dining car.
The utility model is provided with folding device owing to having adopted between the front and rear row leg, the structure that is movably hinged by articulated jib between mounting plate and front-seat leg or the back row's leg, can rotate mounting plate when not using and stand in the leg side, again leg be folded up, the dining car volume is dwindled greatly.The utility model simple and ingenious structure, volume is little, in light weight, production cost is low, can fold use flexibly, be convenient to transportation and carry, it is smaller as the use of places such as family or cafeteria to be adapted at some spaces, and motor-driven carrying is used in the time of also can being adapted at outdoor activities.
Below in conjunction with accompanying drawing the utility model is further described.
