Abstract

The invention discloses a joint structure of a foldable baby stroller. The joint structure comprises inner joints and outer joints rotationally connected, wherein positioning pieces are arranged between the inner joints and the outer joints, and are fixed on the inner joints; slide blocks capable of sliding corresponding to the positioning pieces are arranged between the positioning pieces and the inner joints; pressure springs are arranged between the slide blocks and the outer joints; through holes are formed in the positioning pieces; balls are mounted in the through holes; the thicknesses of the through hole parts of the positioning pieces are smaller than the diameters of the balls; first side surfaces, near the balls, of the slide blocks are provided with first counter bores corresponding to the balls; second side surfaces, near the balls, of the outer joints are provided with second counter bores corresponding to the balls; the sum of the depths of the first counter bores and the thicknesses of the through hole parts of the positioning pieces is greater than the diameters of the balls; the sum of the depths of the second counter bores and the thicknesses of the through hole parts of the positioning pieces is greater than the diameters of the balls; and operation mechanisms for driving the slide blocks to slide are arranged on the inner joints. The joint structure realizes the locking or unlocking of the outer joints through the movement of the balls, so that the structure is simple, the operation is convenient, and the cost is lower.

Description

technical field [0001] The invention relates to a foldable baby stroller, in particular to a joint structure of the foldable baby stroller. Background technique [0002] Baby strollers are already a necessary tool for infants and young children to travel. In addition to pursuing the basic requirements of stability and safety of baby strollers, users pay more and more attention to the characteristics of small size, light weight, and foldable baby strollers. The baby stroller with the above characteristics can be easily tied up and placed in the trunk of the car, and the volume occupied by it can also be reduced on the bus or train, which greatly facilitates travel and portability. [0003] The joint structure of the existing baby stroller includes an inner joint arranged at the end of one frame assembly, and an outer joint arranged at the end of the other frame assembly. The inner and outer joints are rotatably connected. A locking mechanism is provided between the inner and...
