Detailed Description

The utility model is further described in the following embodiments with reference to the figures, see fig. 1-4:

the utility model provides a multi-functional children's shallow, includes frame 1 that has the expansion state and sets up seat device 2 on frame 1, a serial communication port, frame 1 includes preceding roof beam structure 10, back roof beam structure 11 and rotates the manual push rod 12 of connecting in preceding roof beam structure 10 upper end, is provided with the seat base 13 that the level placed on the preceding roof beam structure 10, seat device 2 is including rotating the seat 3 of connecting on seat base 13, and one side of seat 3 is connected with back board 30 through hinge mechanism, and the back of back board 30 articulates there is back bracing piece 31, and the pin joint of back bracing piece 31 is located its top, be fixed with on the preceding roof beam structure 10 little footboard 14, offer on the little footboard 14 with jack 140 of back bracing piece 31 bottom looks adaptation.

In use, there are two use states:

one is to normally put the seat forward, the child sits on the seat, and the child steps on the small pedals with both feet.

The other is, rotate 180 degrees with the seat through on the seat base, the seat is backward this moment, if children are in the position of sitting, its main stress point is in with seat department, if children need lie on lying, turns over the back board downwards, turns over the back in inserting jack 140 on the little footboard with the bottom of back bracing piece again after turning over, because of the atress point under the state of lying on lying this moment will be used on the back board, and the back bracing piece that provides effectively provides the support, ensures children's safe handling. Meanwhile, the pressure of the hinge mechanism is effectively shared by the use of the backrest support rod, so that the service life of the child stroller is longer.

It is worth mentioning that, above-mentioned hinge mechanism is at the circular ring gear of backboard lower extreme shaping to also shaping circular ring gear in one side of seat, when two parts articulated, set up special gear between the circular ring gear of both, and this gear can cooperate with two ring gears, and set up ratchet structure in arbitrary one side, make things convenient for the segmentation fixed.

Preferably, a rectangular inserting rod 15 is formed below the small pedal 14, a rectangular inserting hole 16 adapted to the rectangular inserting rod 15 is formed on the front beam frame 10, and a locking hole 160 penetrating through the side wall of the rectangular inserting rod 15 is formed on the side wall of the front beam frame 10.

In the implementation process, the small pedal 14 is fixed on the front beam frame 10 in a plugging manner, and is penetrated in the locking hole 160 in a bolt manner, so that the locking and fixing effects are achieved.

Preferably, the upper end of the seat base 13 is formed with a turntable 130, a rotation hole 131 is formed in the middle of the turntable 130, a rotation shaft 32 adapted to the rotation hole 131 is formed at the bottom of the seat 3, and a ring 33 for sleeving the outer wall of the turntable 130 is formed at the bottom of the seat 3.

In the implementation process, in order to enable the seat to rotate on the seat base, the seat cannot deflect or incline at will under the normal use state.
