Description

Large joint mechanism capable of rapidly collecting vehicles forwards and backwards and directly lifting and walking Technical Field The utility model relates to the technical field of large joints of frames, in particular to a large joint mechanism capable of rapidly retracting a vehicle back and forth and directly lifting the vehicle to walk. Background The large joint of the frame of the baby stroller is a joint structure for connecting the front leg and the rear leg of the stroller, generally comprises a front hinging seat and a rear hinging seat, and is connected with a connecting shaft through a linkage piece. The design of the joint structure enables the handcart to be smaller after being folded, and is convenient to carry and store. The existing infant stroller frame is generally folded by adopting the design of specific structures such as a linkage piece, a connecting shaft and the like, so that the operation is troublesome, and the folded stroller frame is inconvenient to carry, thereby reducing the practicability of the device, and the large joint mechanism capable of rapidly taking up the stroller back and forth and directly lifting for walking is provided. Disclosure of utility model In order to solve the problems of troublesome operation and inconvenient carrying of the existing infant stroller frame during folding in the background technology, the utility model provides the large joint mechanism which can rapidly retract the stroller back and forth and directly lift for walking.
