In this embodiment, base 1 is discoid, and on the left and right sides direction of children's shallow, base 1, first connecting seat 2, second connecting seat 3 set gradually from the extroversion inwards, so, first connecting seat 2 and second connecting seat 3 can be sheltered from to the outside to base 1 for children's shallow is more succinct pleasing to the eye in appearance.

Referring to fig. 1 and 9, the stroller of this embodiment has an unfolded state and a folded state, and further includes a locking device for locking the stroller in the unfolded state, and the specific structure of the locking device may adopt the prior art, but the invention is not limited thereto.

The working principle of the stroller in this embodiment is specifically described as follows:

referring to fig. 1 to 5, when the stroller is in the unfolded state, the rear wheel bracket 100, the push rod bracket 200, and the front wheel bracket 300 are unfolded relatively, and the pin 21 is located at one end of the sliding groove 31.

Referring to fig. 6 to 8, when the stroller needs to be folded, the locking mechanism is first unlocked, so that the push rod frame 200 rotates downward around the first rotation center line X under the action of its own gravity, in this process, the pin 21 slides forward along the sliding slot 31, abuts against the side wall of the sliding slot 31 and rotates relatively, and drives the front wheel bracket 300 to rotate around the second rotation center line Y, that is, in the process that the push rod frame 200 rotates toward the rear wheel bracket 100 and approaches, the linked front wheel bracket 300 also rotates toward the rear wheel bracket 100 and approaches.

Referring to fig. 9 to 11, when the stroller is folded, the push rod frame 200 and the front wheel bracket 300 are respectively folded at both sides of the rear wheel bracket 100, and the pin 21 slides along the sliding groove 31 and rotates to the upper end of the sliding groove 31.

When the stroller needs to be unfolded again, the push rod frame 200 is driven to rotate upwards around the first rotation center line X only by reversely operating the steps, the linkage structure can link the front wheel support 300 to rotate and unfold relative to the rear wheel support 100, and the locking mechanism is locked when the stroller is completely unfolded, so that the unfolding can be completed, and the operation is very simple and convenient.

In this embodiment, children's shallow is folding or the in-process that expandes, only need order about push rod frame 200 and rotate, just can link whole car folding or expansion, especially folding in-process, push rod frame 200 just can rotate automatically under the effect of self gravity and fold up, and is very convenient.

Example 2

Referring to fig. 12 to 17, in the present embodiment, the children article is exemplified by a children sleeping basket, which also includes two sets of side brackets respectively disposed at the left and right sides, each set of side bracket includes a side link 400, a seat bracket 500 and a back bracket 600 rotatably connected to each other, wherein the side link 400 constitutes a base rod, the seat bracket 500 constitutes a first bracket rod, the back bracket 600 constitutes a second bracket rod, and the structure of a rotary joint formed by the connection of the three is substantially the same as that of embodiment 1.

In this embodiment, the children sleeping basket further comprises an annular enclosing frame 700, the enclosing frame 700 is disposed between the two sets of side brackets and rotatably connected to the upper ends of the two sets of side connecting rods 400, and two sides of the enclosing frame 700 are respectively provided with a connecting member 4 for detachably connecting the children sleeping basket with a stroller frame, a bed frame or other external devices.

In this embodiment, the base 1 is fixedly installed at the lower end of the side link 400, the seat frame 500 is located at the front side of the side link 400, and the back frame 600 is located at the rear side of the side link 400, and when the seat frame 500 rotates toward the side link 400, it is possible to link the back frame 600 to rotate toward the side link 400, similarly to embodiment 1.

In this embodiment, in the left and right direction of the children sleeping basket, the base 1, the first connecting seat 2, and the second connecting seat 3 are sequentially disposed from inside to outside, so that the surrounding frame 700 is relatively located at the inner sides of the seat frame 500 and the backrest frame 600, and flexible materials such as cloth are wrapped between the rods to form a bearing space for the children to sit and lie.

Specifically, the children sleeping basket has a sitting posture state and a lying posture state, as shown in fig. 16 to 17, in the lying posture state, the seat frame 500 and the backrest frame 600 are relatively unfolded and both extend in the horizontal direction, and the enclosure frame 700 also extends in the horizontal direction, so that the children can lie in the carrying space.

Referring to fig. 18 to 21, when the child sleeping basket needs to be adjusted to a sitting posture, the seat frame 500 is driven to rotate upward around the first rotation center line X, the linkage structure enables the backrest frame 600 to rotate around the second rotation center line Y, an included angle between the seat frame 500 and the backrest frame 600 is reduced, the seat frame 500 extends in the front-back direction, the backrest frame 600 extends in the up-down direction, and the enclosure frame 700 is correspondingly changed to extend obliquely upward from front to back, so that the child can sit in the carrying space.

When the child sleeping basket in the sitting posture needs to be adjusted to the lying posture, the steps are only needed to be operated in the reverse direction, the seat frame 500 is driven to rotate away from the side connecting rod 400, and the backrest frame 600 can be driven to rotate away from the side connecting rod 400 in a linkage manner.

In conclusion, in different embodiments, the rotating joints of the children products are simple in structure and small in occupied size, and when the first support rod is driven to rotate relative to the base rod to close or keep away from the base rod, the second support rod can be linked to close or keep away from the base rod to rotate, so that the children products can be adjusted and converted between different states, operation steps are simplified, and the children products are convenient to use.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
