AI Technical Summary
When turning, traditional children's balance bikes are prone to overturning due to the large rotation angle of the front wheels, causing children to fall.
A children's balance bike with anti-rollover is designed. By setting limiting parts and guide rods on the frame, the rotation range of the front wheel is limited and 360 degrees of rotation is prevented. The handle is used to drive the rotating rod and the front wheel frame to rotate. After the positioning member comes into contact with the baffle, the position is adjusted by the spring sleeve and the guide rod to ensure that the rotating rod is rotated to the limit position to prevent rolling.
Effectively prevent children's balance bike from overturning when turning, improves the stability of the vehicle and reduces the risk of children falling.

Technical Field
[0001] The utility model relates to the technical field of balancing vehicles, in particular to a rollover-proof children's balancing vehicle. Background Art
[0002] Children's balance bikes are mainly designed for young children to train their balance ability. Babies need to continuously push the ground with their feet to provide sliding power.
[0003] Traditional balance bikes require children to push the ground to provide power, and the balance of the balance bike also requires children to keep both feet on the ground to maintain balance. The front wheels of children's balance bikes can turn 360 degrees. When facing novice children, in actual use, children cannot control the angle well when turning. When the turning angle is too large, it is very easy to roll over and cause the children to fall.
[0004] In view of this, the present technical solution proposes an anti-rollover children's balance car, which is convenient for better solving the problem of excessive rotation angle of the front wheel. Utility Model Content
[0005] The purpose of the utility model is to provide a children's balance car that can prevent rollover in order to solve the above-mentioned problems.
[0006] The technical solution adopted by the utility model is as follows: an anti-rollover children's balance car, comprising a frame, a rear wheel is rotatably mounted on the right side of the frame, a seat cushion is arranged inside the frame on the left side of the rear wheel, a front mounting tube of the frame is fixed on the left side of the frame, a rotating rod is rotatably mounted inside the front mounting tube of the frame, a front wheel frame is fixed at the bottom end of the rotating rod, and the front wheel is rotatably connected to the inner side of the front wheel frame, and a handle is fixed above the rotating rod;
[0007] A mounting sleeve is installed above the front mounting tube of the frame, and the rotating rod is rotatably connected to the inside of the mounting sleeve, and symmetrically arranged limit members are fixedly connected to the front and rear of the rotating rod inside the mounting sleeve, a fixed frame is penetrated and connected to the right side of the mounting sleeve, and a mounting plate is fixed to the right side of the fixed frame, an extension plate is fixed to the left side of the mounting plate, and the extension plate is plugged into the inside of the fixed frame and the mounting sleeve, cavities are opened in the front and rear of the left side of the extension plate, and a guide rod is movably plugged into the cavity and the extension plate, a spring sleeve is sleeved on the guide rod located inside the cavity, and a limit member baffle is fixed to the ends of the spring sleeve and the guide rod.
[0008] In a preferred embodiment, the connection between the front mounting tube of the frame and the mounting sleeve is mounted by means of a flange and bolts.
[0009] In a preferred embodiment, the fixing frame is mounted on the mounting plate around four sides by second bolts.
[0010] In a preferred embodiment, the length of the extension plate is greater than the length of the fixed frame, and the extension plate is arranged opposite to the rotating rod.
[0011] In a preferred embodiment, a guide hole adapted to the guide rod is opened inside the extension plate, and the guide rod is inserted into the guide hole, and the cavity and the guide hole are in a communicating structure.
[0012] In a preferred embodiment, the length of the spring sleeve is greater than the depth of the cavity, and the rear end of the spring sleeve is fixed behind the inner wall of the cavity.
[0013] In a preferred embodiment, the length and width of the limiter baffle are matched with the length and width of the cavity.
[0014] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are: it is convenient to better perform extreme positioning of the rotation position of the rotating rod, preventing the rotating rod from driving the front wheel frame and the front wheel to rotate 360 degrees, and better preventing children from rolling over due to excessive turns.
[0015] In the utility model, when the handle drives the rotating rod, the front wheel and the front wheel frame to rotate, the rotating rod drives the limit piece to adjust the position. When the limit piece contacts the limit piece baffle, the limit piece baffle moves slightly under the action of the guide rod and the spring sleeve. When the limit piece baffle cannot move, the rotating rod rotates to the extreme position, which better prevents the rotating rod from driving the front wheel frame and the front wheel to rotate 360 degrees, and better prevents children from tipping over due to excessive turns.
