Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

A handle reversing and positioning device of a baby stroller is shown in figure 1 and comprises a stroller frame 1, a reversing main shaft 2 arranged on the stroller frame 1, push rods 3 arranged on two sides of the reversing main shaft 2, and a handle 4 arranged at the tail end of each push rod 3; the bottom of the frame 1 is provided with universal wheels 11; the frame 1 and the reversing spindle 2 are fixed by welding; the handle 4 is provided with a sponge sleeve 41 for improving the holding comfort of the handle 4; the push rod 3 is made of aluminum alloy materials, so that the push rod 3 is light and durable.

As shown in fig. 2, the reversing spindle 2 includes a connecting sleeve 21, a separating plate 22 integrally formed in the connecting sleeve 21, first connecting rings 23 disposed on both sides of the separating plate 22, spindle pipes 24 correspondingly clamped on both sides of the connecting sleeve 21, springs 25 disposed in the spindle pipes 24 and hinged to the first connecting rings 23, a flange 26 disposed at an end of the spindle pipes 24, a first snap ring 27 disposed on the flange 26, and a locking mechanism 28 disposed at an end of the flange 26.

As shown in fig. 3, the locking mechanism 28 includes a first cam 281, a rotating shaft 282 provided on the first cam 281, a second cam 283 provided on the rotating shaft 282 and having one end fixedly connected with the push rod 3, a supporting block 284 provided on the rotating shaft 282, a second connecting ring 285 provided on one end of the supporting block 284, a connecting block 286 provided on the other end of the supporting block 284, and a second snap ring 287 provided on one end of the connecting block 286; the first snap ring 27 and the second snap ring 287 are in a corresponding fit relationship, and under the pulling force of the spring 25, the first snap ring 27 and the second snap ring 287 are mutually clamped, and when the first cam 281 and the second cam 283 rotate, the spring 25 is stretched and the second snap ring 287 is jacked up, so that the first snap ring 27 and the second snap ring 287 are separated, the handle 4 is unlocked, and the handle 4 is convenient to change directions.
