[0042] The specific implementation of the utility model is described below in combination with the drawings and examples:
[0043] refer to Figures 1 to 3 , three state schematic views of the embodiment, wherein Figure 1 The child vehicle mainly applies in the scene of children playing, and is the main design of the embodiment; Figure 2For rocking chair state, the cloth pocket is arranged on the ring beam, and the legs and universal wheels under the chassis are all retracted; Figure 3 The angle between the ring beam and the chassis is less than 90°, and the push handle is provided, and the universal wheels are selected under the chassis, so that the child can move by pushing the push handle to learn walking; in order to facilitate walking, the direction of the cross beam is changed to avoid stirring the foot.
[0044] In order to realize the above three states and facilitate the switching of the three states, the child's vehicle provided in the embodiment comprises a chassis, an inclined beam and a ring beam, wherein the inclined beam is provided with two; the ring beam is located above the chassis, and the two inclined beams are respectively located on the two sides of the two to serve as supports. In order to further realize the multi-angle rotation of the ring beam, especially the switching of the first three states and the fourth state, the upper rotation joint and the lower rotation joint are adopted for realization, and reference is made to Figures 4 to 9 The specific structure of the rotation joint is as follows:
[0045] The upper rotation joint and the lower rotation joint both comprise a locking wheel, a support and a hinged piece, the inner side of the support and the inner side of the hinged piece are both provided with a clamping groove; the clamping grooves of the support and the hinged piece are clamped to form a clamping cavity; the locking wheel is located in the clamping cavity; the clamping groove of the support is provided with a rotating shaft at the center, and the locking wheel is sleeved on the rotating shaft, wherein the locking wheel and the hinged piece both have the freedom of relative rotation along the rotating shaft; the annular wall of the clamping groove is provided with a tooth groove, and the locking wheel is provided with a locking tooth extending along the diameter direction thereof, and the locking tooth is located in the corresponding tooth groove.
[0046] The outer side of the hinged piece is provided with a button penetrating into the clamping groove thereof through a through hole; the inner end of the button abuts against one surface of the locking wheel; the clamping groove of the support is provided with a spring, and one end of the spring abuts against the other surface of the locking wheel. When the upper rotation joint or the lower rotation joint needs to be rotated, the button is pressed, the inner end of the button abuts against the locking wheel, the spring is compressed, the locking wheel is pressed into the clamping groove of the support, and the locking tooth on the locking wheel is separated from the tooth groove of the hinged piece, at this time, the force of rotation is applied to the support and the hinged piece, and they are brought to the appropriate relative position of rotation, the button is released, the spring rebounds, the locking wheel straddles the support and the hinged piece, and the locking tooth is embedded in the tooth grooves of the two to prevent rotation; in the locked state of the rotation joint, part of the locking tooth of the locking wheel is located in the tooth groove of the support, and the other part is located in the tooth groove of the hinged piece.
[0047] The upper rotation joint is installed at the top of the inclined beam to realize the connection of the inclined beam and the ring beam, and the lower rotation joint is installed at the bottom of the inclined beam to realize the connection of the inclined beam and the chassis.

A vertical positioning structure is provided on the side of the insertion structure. The specific structure will be described in detail with reference to Figure 10 and Figure 7 The corresponding prism ( Figure 10 on both sides of the elastic insertion plate a) and the prism hole ( Figure 7 on both sides of the insertion slot a) are inserted into each other.
[0050] In order to facilitate children to have meals and play, this embodiment also provides a matching dining table plate. The specific structure of the dining table plate will be described in detail with reference to Figure 12 、 Figure 13 、 Figure 14 and three state diagrams ( Figure 1 ). The dining table plate is installed in front of the ring beam, and one side of the dining table plate is adapted to the arc-shaped edge at the front end of the ring beam. The upper half of the inclined beam is provided with a support block vertically upward. The top of the support block is provided with an elastic insertion plate b, and the elastic insertion plate b is provided with a protrusion b. The bottom of the ring beam is provided with an insertion slot b, and one side of the insertion slot b is provided with a window b. The elastic insertion plate b is inserted into the insertion slot b, and the protrusion b abuts against the edge of the window b. The vertical positioning of the dining table plate is achieved by the prism form of the support block itself and the prism hole form of the insertion slot b.
[0051] Children play mainly by inserting two types of clamping in the dining area on the dining table plate. One side of the music box is slid to the clamping A type, and then the music box is pressed to make the positioning insertion plate below the music box inserted into the clamping B type. A hanging rod is inserted into the clamping hole, and a bell is installed at the end of the hanging rod to form a hanging toy. The insertion end of the hanging rod can rotate freely in the clamping hole.
[0052] Especially in the state of the children's walker ( Figure 3 ), a push handle needs to be inserted at the rear of the ring.
[0053] The utility model does not elaborate part belongs to the technology of the technical personnel.
