Handle folding structure for baby stroller

Abstract

The invention discloses a handle folding structure used for a baby carriage. The handle folding structure has a double-side steel rope structure; steel ropes on the two sides can be pulled through folding a handle, so that main joints are unlocked. The handle folding structure comprises a locking assembly, a folding structure which is folded and bent in one direction by taking the locking assembly as the center and is composed of a first handle (71) and a second handle (72), a first steel rope (14) and a second steel rope (15); the locking assembly comprises a key (81), a latch (82), a first rotary joint (83), a second rotary joint (84), a latch resetting spring (85) and a connection shaft (87); the latch (82) is arranged between the first rotary joint (83) and the second rotary joint (84) and can slide up and down; the latch resetting spring (85) is tightly pressed between the first rotary joint (83) and the latch (82); the first steel rope (14) is detachably connected with the second rotary joint (84); and the second steel rope (15) is crossed with the first steel rope (14) and is detachably connected with the first rotary joint (83).

Description

technical field [0001] The invention relates to the mechanical field, in particular to a handle folding structure for a stroller. Background technique [0002] As a portable tool for carrying infants and young children, the baby carriage solves the troublesome problem when people go out with babies, and greatly reduces the burden of carrying infants and young children when people go out. Due to the relatively large volume of the baby carriage, it takes up a large space when not in use. In order to solve this problem, a corresponding folding mechanism is provided on the baby carriage, so that the baby carriage can be folded, thereby reducing the volume and facilitating carrying and transportation. [0003] The handle folding structure of the present collapsible stroller often causes a series of problems due to its structural design. see figure 1 , which is an exploded view of a handle folding structure of a stroller in the prior art. The handle folding structure includes:...

AI Technical Summary

Problems solved by technology

[0004] However, since the handlebars of the stroller are arranged symmetrically, the above method of unlocking the main joint with the single-sided steel cable can only solve the problem of unlocking the main joint on one side, while the other main joint has no corresponding unlocking structure of the steel cable. Cause another test to close is often blocked

And installing another steel cable in the above-mentioned handle folding structure faces the following problems: one, because the steel cable needs to pass through the through hole on the rotating shaft, and then be fixedly connected with the cable fixing part, and because the steel cable fixing part and the rotating shaft The volume is large, occupying most of the space between the left and right rotating joints, so the narrow space does not provide conditions for installing another steel cable

The steel cable on the extended side cannot unlock the main joint
