Abstract

The utility model provides a baby carriage structure including a main body, a support frame and a bar group. The support frame is arranged on and connected with the bottom of the main body, and can support two rear wheels and two front wheels. The bar group passes through the center of the main body, and a handle and a pedal lever are arranged respectively above and under the bar group which pulls a chain, so as to drive gears to rotate the two rear wheels. A spring is used for the reconversion of the chain and the bar group. A steering bar is articulated with the lower part of the handle and deflects a displacement bar through a short bar. The displacement bar is linked with two steering components to enable the two front wheels to deviate, thereby achieving direction control.

Description

The structure of perambulator

(1) technical field:

The structure of a kind of perambulator of the utility model, relevant with perambulator, more detailed it, especially finger can control turn to, transmission is advanced and the structure of a kind of perambulator of braking, belongs to articles for children.

(2) background technology:

Children need the body and mind balanced development, and except education, toy for children also can make body movement, and inspires its intelligence, and toy for children is not only wanted to attract children, and interesting, joyful and safety.

The perambulator of Xiao Shouing with foot pedal do rotation refining bar, drives wheel or direct foot pedal drive wheel nothing more than being to supply children's ride-on in the market, again so that hand shift is turned to, there is no any novel improvement part, and children lack interest in the course of time.

Also have various perambulators, have with the twisting vehicle body turn to as wheel and move forward turn round car, also have with the vehicle body that will turn round car to be incorporated into Pedal pram, however in stays, poor effect.

(3) novel content:

The structure of a kind of perambulator of the utility model its objective is: providing can be with the structure that hand shift front-wheel steering and transmission are advanced, and available treadle transmission is simultaneously advanced, and children are used both hands and feet, and has the perambulator of interesting and safety

The structure of a kind of perambulator of the utility model, it includes:

One main body is a housing, and there is seat board at the rear, and middle-end has perforation, and there are two extension rods in the place ahead;

One bracing frame contains support before support after two trailing wheels, several central poles and two front-wheels;

One bar group, top are handle, and the below is a treadle, the bar group is articulated between several central poles, and bar group pulling one refining bar, driven gear and rotate two trailing wheels, there is a spring to connect and is located between chain and the bar group, restore to the original state, unilateral bearing is arranged in the gear to drive a transmission shaft for chain and bar group;

It is characterized in that: this handle below articulates a deflecting bar in addition, and this deflecting bar is with a quarter butt beat one displacement bar, and displacement bar then connects and rotates two steering assemblies, make two before the crop rotations deflection, reach control to purpose.

Wherein, this bar group is arranged in the perforation of main body, and the bar group is provided with two horizontal nose bars and is articulated within the main body, and is that deflection handle and treadle are made in the center with this horizontal nose bar.

Wherein, this bar group is positioned at two horizontal nose bar belows two position-limited levers, with respect to central pole below two spacing spaces is arranged, and this position-limited lever is gone in the spacing space, makes handle and treadle do the deflection of a predetermined angular.

Wherein, this steering assembly is a U template, and the U template extends an arm-tie, and the outer side joint of this U template is established front wheel spindle, bar before interior side joint establishes, and support is articulated before this preceding bar and the bracing frame.

Wherein, this front-wheel respectively has Anti-slip belt with the back wheel surface.

Wherein, support articulates a brake lever after this bracing frame, and this brake lever is via the pull-up of a hand lever, but brake lever two ends braking rear-wheel.

The structure of a kind of perambulator of the utility model, its advantage is: it can be with the structure that hand shift front-wheel steering and transmission are advanced, and available treadle transmission is simultaneously advanced, and children are used both hands and feet, and has entertaining and safety.
