Description

A baby stroller whose seat is rotated to realize reversing

technical field

The invention relates to the technical field of baby stroller equipment, in particular to a baby stroller whose seat is rotated to realize direction change.

Background technique

A stroller is an indispensable product for infants and young children to grow up. At present, some baby strollers have the function of reversing the seat, but the reversing mechanism thereof is complicated and inconvenient to operate and use.

In addition, the current baby strollers can generally be folded for easy carrying and storage, but the traditional baby strollers are bulky when folded and complicated to operate when folded, so there is still room for improvement.

[Chinese invention] Fixed shaft 1.1N201911278166.9 A seat reversing mechanism and a baby stroller, which includes: a seat bracket 10, which is movably arranged on the frame body 200 of the baby stroller, and can be retracted along with the frame body 200. The seat plate 20 is movably arranged on the seat bracket 10 and can be rotated horizontally relative to the seat bracket 10. In this application, the seat plate 20 will be restricted by the front strut 240 when it rotates, resulting in the replacement of the seat plate 20. The direction is inconvenient, and the direction can only be changed within a range of 180°, and the direction of the change is small. At the same time, the structure of the baby stroller is complicated, which leads to high cost.

To this end, we propose a stroller whose seat can be rotated to achieve reversal.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to accompanying drawings 1-4, a baby stroller whose seat is rotated to realize reversal includes a support assembly 2 and a seat 3 above the support assembly 2, and a seat base is arranged between the support assembly 2 and the seat 3 1, the seat base 1 is rotatably connected to the upper end of the support assembly 2; the seat base 1 is provided with an annular groove a, and the seat 3 is provided with a rotating block 3.2 that can rotate in the annular groove a, through the rotating block 3.2 and The mutual cooperation of the annular grooves a can realize the 360° rotation of the seat 3 on the seat base 1 , thereby increasing the scope of application.

In this embodiment, as shown in Figures 1-4, a backrest 3.1 is hinged on one end of the seat 3. The backrest 3.1 can be rotated relative to the seat 3, which can realize multiple modes such as sitting and lying down. The same push rod assembly 4 is hinged on the end side wall. The connection between the push rod assembly 4 and the seat 3 and the backrest 3.1 and the seat 3 is provided with a rotating joint. The rotating joint includes a rotating joint stator and a rotating joint rotor, which can be easily rotated. The push rod assembly 4 adjusts the pushing direction of the stroller, and can choose to push the stroller face-to-face with the baby, or choose to push the stroller on the back of the baby. To prevent the baby from falling from both ends, play a certain protective role.
