Abstract

The utility model relates to a leap-moving type body-building tricycle for children. The front wheel and the handle bar parts of the tricycle is identical with the existing tricycle for children; a crank shaft which connects two rear wheels are arranged on the central position of the two rear wheels. One end of a cross beam of the tricycle is fixed to a support frame of the handle bars, and the other end is fixed to a rear frame of the tricycle. One end of a connection rod of the crank shaft is hinged with the cross beam of the tricycle, and the other end is arranged on the bottom of a saddle; the saddle produces up and down leap movement under the action of the connection rod of the crank shaft. The utility model can leap up and down simultaneously as runs forward; children can exercise the consistency between each part of the body and the brain during body-building; in addition, the leap-moving type body-building tricycle for children has the advantages of stability and safety.

Description

A kind of leap-moving type stationary bike for children

The utility model relates to a kind of leap-moving type stationary bike for children.

At present, existing carriage for children, no matter be three-wheel or two-wheeled, all move ahead only, function singleness does not have help to the coordination ability between training children's brain and the health each several part in body-building, and disclosing a kind of " children's body-building travel the driving that jumps " this car in the Chinese patent 90312189.8 is two-wheeled, under the drive of axle and chain, make car when moving ahead, rhythmicity was quivered about vehicle seat can carry children's work, to reach the body-building purpose simultaneously, the harmony of training child motor, but this bassinet structure complexity, and owing to be two wheel constructions, therefore, less stable is restricted its practical application.

The purpose of this utility model is at the prior art above shortcomings, and a kind of leap-moving type stationary bike for children is provided, and this car not only can quiver vehicle seat up and down when moving ahead, and simple in structure, good stability.

The purpose of this utility model is achieved in that a kind of leap-moving type stationary bike for children, by a front-wheel, pin turns, pedal, handlebar, the car crossbeam, vehicle seat, two trailing wheels, bent axle and connecting rod constitute, the structure of front-wheel and the mounting means of handlebar are all identical with existing child's tricycle, the two ends that it is characterized in that this car bent axle are installed on two trailing wheels as the wheel shaft of two trailing wheels respectively, one end of car crossbeam is fixed on the handlebar support, the other end is fixed on the car after-frame, be hinged between car after-frame and the bent axle, one end and the bent axle of bent wheel connecting rod are hinged, the other end is installed in the vehicle seat bottom, one end and the car crossbeam of vehicle seat support are hinged, and the other end is installed in the vehicle seat bottom.

The utility model compared with prior art has the following advantages: 1, because the utility model connects two trailing wheels with bent axle, connect vehicle seat and bent axle with song wheel connecting rod, therefore, can make the utility model under the drive of pedal, when moving ahead, produce and quiver up and down, reach the purpose of training child motor harmony; 2, because this practical purpose of utilizing crankshaft-link rod to reach to quiver, therefore knot is simple; 3, because the utility model is three wheel constructions, therefore have good stability, when riding, safe and reliable.

With most preferred embodiment of the present utility model in detail the utility model is described in detail below in conjunction with accompanying drawing.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is the structural representation of the utility model trailing wheel and bent axle connecting bridge;

Fig. 3 is the structural representation of vehicle seat of the present utility model bottom;

Fig. 4 is the structural representation of installation ring of the present utility model.

As Fig. 1, shown in Figure 2, the structure of the utility model front-wheel part, pedal, pin turn and the mounting means of handlebar all identical with existing child's tricycle, the two ends of bent axle 10 are installed in two trailing wheels 8 respectively, 12 center, and as two trailing wheels 8,12 wheel shaft, one end of car crossbeam 5 is fixed on the handlebar support 1, the other end is fixed on the car after-frame 9, be hinged between car after-frame 9 and the bent axle 10, one end and the bent axle 10 of crankshaft-link rod 11 are hinged, the other end is hinged with the installation ring 18 that is fixedly mounted in the vehicle seat 7 bottom mounting grooves 17, one end of vehicle seat support 6 is installed in the vehicle seat support mounting groove 14 of vehicle seat 7 bottoms, the other end and car crossbeam 5 are hinged, quiver steadily in order to make the utility model, make to ride over top children and feel more comfortable, an end of two damping springs 13 is installed in the spring mounting groove 15 of vehicle seat 7 bottoms respectively, the other end of 16 inner springs 13 is installed in respectively on the car after-frame 9.

When children ride on the vehicle seat 7, drive pedal 3 by pedal with bipod, drive front-wheel 2, two trailing wheels 8,12 just move ahead with front-wheel, trailing wheel 8,12 drive bent axle 10, and bent axle 10 drives crankshaft-link rod 11, and 11 of crankshaft-link rods drive vehicle seat 7 upper and lower fluctuatings, make the utility model when moving ahead, quiver up and down, drive children in the exercise health, trained the coordination ability of each several parts such as both arms, both feet, and therefore because the utility model is a tricycle structure, operate steadily, safe and reliable.
