Foldable baby carriage capable of being pushed in reverse direction

Abstract

The invention discloses a foldable baby carriage capable of being pushed in a reverse direction. The invention is characterized in that a push-hold frame is provided with an inverting handle interlocked with a pulling cable; the pulling cable is connected with a positioning piece connecting seat which forms a positioning piece; the upper end of the connecting seat jacks up an offsetting spring; the other end of the offsetting props against the inside of the push-hole frame upwards; the side of an upper inverting seat is provided with a kidney-shaped hole and the positioning piece penetrates through the hole; a first positioning part and a second positioning part are formed at a lower inverting seat and are matched with the positioning piece; a first guide surface is formed between the two positioning parts for transition; when the push-hold frame is pushed in a forward direction, the positioning component penetrates through the kidney-shaped hole and is clamped at the first positioning part; the positioning component slides to be clamped at the second positioning part along the first guide surface, and by this time, the push-hold frame is pushed in a reverse direction; both ends of a rear hood frame are rotatably connected with the lower inverting seat; and a retracting device is arranged between the rear hood frame and the lower inverting seat. The invention has the advantages of high strength of the reverse mechanism, reliable inverting and folding operation, smooth conversion, adjustable angle of the backrest and small volume because front wall components are retracted inwards after being folded.

Description

technical field [0001] The invention belongs to the technical field of baby carriage manufacturing, in particular to a foldable baby carriage that can be reversed and pushed. Background technique [0002] At present, there are foldable baby carriages in the market where the push handle frame can be turned over to achieve reversing promotion, and it is very popular among users because of its advantages of flexibility and mobility. Chinese Patent No. ZL200820000625.8 discloses a foldable stroller, which includes front wheels, rear wheels, front legs extending obliquely upward relative to the front wheels, and a push handle frame hinged to the front legs. The reversing mechanism is rotatably connected, and the reversing mechanism includes a front leg connecting seat and a push handle frame connecting seat that are engaged with each other. The push handle frame connecting seat and the front leg connecting seat are within a certain angle range Relatively rotating, when the two l...

AI Technical Summary

Problems solved by technology

The defect in the above-mentioned patented technical solution is: when pushing forward, the axes of the front legs and the push handle frame are not in the same straight line, and when the reverse is pushed, the front legs and the push handle frame are not in the same plane, thus connecting the two The support force that the reversing mechanism can withstand is small, and it is easy to be crushed, and the staggered front legs and push handle frame are easy to pinch fingers during relative rotation, posing a safety hazard; in addition, after folding, the dinner plate is always It is in the most protruding part, therefore, its volume after folding is large; finally, the structure of push handle frame with plug-in fit is not easy to process, and the production cost is also high
