Abstract

The utility model discloses a cycle for children, particularly a multifunction children's body-building cycle. An ordinary children's tricycle is additionally provided with a driving mechanism for wobbling chairs and an adjustable eccentricity device for a back wheel shaft, wherein, the driving mechanism for wobbling chairs is composed of a front and a back beams, a tension spring, a driving rod, and a ratchet mechanism; the front beam and the back beam are mutually hinged, and the ratchet mechanism is positioned on the back wheel shaft; the adjustable eccentricity device for a back wheel shaft is composed of a back wheel frame, an eccentricity sleeve, and a fastening screw bolt. The utility model has the advantages that the structure is reasonable, and the functions are complete; the utility model can be used for being ridden as the ordinary children's tricycle; the utility model can make the cycle body jump up and down during riding like a horse; the utility model can forward move when children sit on the seat, wobble, or jump up and down.

Description

The multifunctional children body-building vehicle

The utility model relates to a kind of perambulator, particularly a kind of multifunctional children body-building vehicle.

Traditional perambulator is by foot-operated transmission, function singleness, child generally lacks interest to it, need in the market a kind of multiple functional, recreational strong perambulator.

The new purpose of this practicality will provide a kind of exactly and can ride as common toy tricycle, can also be implemented in vehicle body bob in the process of riding, as long as and rock the multifunctional children body-building vehicle that seat also can move forward.

The utility model adopts technical scheme as described below for achieving the above object: the multifunctional child body-building vehicle comprises front-wheel, trailing wheel, handlebar, rolling chair, pedal and eyeball awning, pedal is fixedly connected on the wheel shaft of front-wheel, and child just can ride as riding common three-wheel vehicle perambulator like this.It has chair transmission device in a flash, the front-axle beam and the back rest are hinged, and their hinged axle bed is fixed on rolling chair bottom, between the front-axle beam of jointed shaft bottom and the back rest, be connected with extension spring, a ratchet device is arranged on the hind axle, there is drive link the bottom of rolling chair in the position, back partially, drive link one end is hinged with the rolling chair, and the other end has ratchet can stir ratchet device, when child rocks on the rolling chair, rock before and after the rolling chair, drive link is stirred ratchet moves forward perambulator, and when child beated on the rolling chair, front-axle beam and back rest angle changed, front-wheel and trailing wheel spacing change, and dolly is gone ahead.A hind axle adjustable eccentric device is arranged on the trailing wheel, this device can be implemented in vehicle body energy bob in the process of riding, decentralizing device is by rear wheel frame, eccentric bushing and binding bolt are formed, rear wheel frame has one to change the hole in the position of its disalignment, eccentric bushing and commentaries on classics hole normal-running fit, eccentric bushing one end has B shape plate, and the other end has baffle plate, also has trailing wheel axis hole and several fixing threaded hole on the eccentric bushing, hind axle is positioned on the trailing wheel axis hole, passing fixing threaded hole with bolt can be fixed on baffle plate and B shape plate on the eccentric bushing, and it can prevent that eccentric bushing from skidding off, and has chute on the B shape plate from change the hole, the screw of the binding bolt of chute on the rear wheel frame, during the tuningout heart, binding bolt is unclamped, rotate B shape plate, make the skew of trailing wheel axis hole center, increase eccentric distance, vehicle body gets final product bob in the process of riding like this, and Oscillation Amplitude is adjustable.

Adopt the multifunctional children body-building vehicle of said structure rational in infrastructure, multiple functional, recreational strong, be particularly suitable for the needs of children physiology and psychology.

Be described in further detail this reality is novel below in conjunction with accompanying drawing.

Fig. 1 is the later-model structural representation of this reality.

Fig. 2 is a hind axle adjustable eccentric device scheme drawing.

Fig. 3 is the cutaway view of hind axle adjustable eccentric device.

Fig. 4 is the circuit diagram of music box.

With reference to Fig. 1.The multifunctional children body-building vehicle comprises front-wheel 10, trailing wheel 6, handlebar 1, rolling chair 2, pedal 12 and eyeball awning 3, and pedal 12 is fixedly connected on the wheel shaft of front-wheel 10, and child just can ride as riding common toy tricycle like this.The front-axle beam 11 and the back rest 8 are hinged by axle 19, the bearing seat of axle 19 is fixed on the bottom of rolling chair, be connected with extension spring 9 between the front-axle beam 11 of jointed shaft 19 bottoms and the back rest 8, a ratchet device is arranged on the hind axle 7, there is drive link 5 bottom of rolling chair 2 in the position, back partially, drive link 5 one ends are hinged with rolling chair 2, the other end has ratchet can stir ratchet device, when child rocks on the rolling chair, rocks before and after the rolling chair, drive link 5 is stirred ratchet moves forward perambulator, when child beated on the rolling chair, extension spring 9 stretched, and front-axle beam and back rest angle change, front-wheel and trailing wheel spacing change, dolly is gone ahead, and extension spring 9 also can be played buffer action, is not subjected to hard impact when child is beated on vehicle seat, and very comfortable, have the same sensation of riding.

With reference to Fig. 2, Fig. 3.A hind axle adjustable eccentric device is arranged on the trailing wheel 6, decentralizing device is by rear wheel frame 17, eccentric bushing 16 and binding bolt are formed, rear wheel frame 17 has one to change hole 21 in its position, disalignment, eccentric bushing and commentaries on classics hole normal-running fit, eccentric bushing 16 1 ends have B shape plate 23, the other end has baffle plate 20, also have trailing wheel axis hole 22 and several fixing threaded hole 14 on the eccentric bushing, hind axle 7 is positioned on the trailing wheel axis hole 22, passing fixing threaded hole 14 with bolt can be fixed on baffle plate and B shape plate on the eccentric bushing, it can prevent that eccentric bushing from skidding off from change the hole, on the B shape plate 23 chute 15 is arranged, chute 15 faces the screw 13 of the binding bolt on the rear wheel frame 17, during the tuningout heart, binding bolt is unclamped, rotate B shape plate, eccentric bushing rotates along the axle center 18 of changeing hole 21, make the axle center of trailing wheel axis hole 22 skew rear wheel frames, it is many more that B shape plate 23 rotates, and the distance in axle center that trailing wheel axis hole 22 departs from rear wheel frame is big more, be transferred to correct position after, holding screw is screwed in to tighten on the screw 13 gets final product, accentric distance can be between 0-25mm regulated at will, vehicle body gets final product bob in the process of riding like this, and adjustable its amplitude.

Be connected on the backrest of this car rolling chair and be connected to handrail 4, the adult can push away dolly and advance.

With reference to Fig. 4.There is a music box 24 the handlebar front portion, comprises music-integrating block MH218, indicator lamp D, K switch, loud speaker Y, power supply in the music box, and it can increase recreational in child rides process.
