Abstract

A children's exercise bicycle is formed by assembling a steering yoke (1), a height adjusting clamp (2), a folding clamp (3), a frame (4), a brake (5), pedals (6), connecting rods (7), unidirectional torsion rocker arms (8), wheels (9), speed changing gears (10), return springs (11), a front fork (12), a directional front wheel (13), pedal height positioning rods (14) and a pedal supporting positioning plate (15). The front fork (12), the steering yoke (1), the height adjusting clamp (2), the folding clamp (3) and the brake (5) are connected with the frame (4), front ends of the pedals are connected with the frame (4), the return springs (11) are installed at the front ends of the pedals, the connecting rods are arranged at rear ends of the pedals to be connected with the unidirectional torsion rocker arms (8), the unidirectional torsion rocker arms (8) drive the speed changing gears (10) through shafts, and rear shafts of the speed changing gears (10) drive a rear wheel to move. The children's exercise bicycle is characterized in that the bicycle body is low, the pedals return to the original positions by the aid of the return springs (11), the unidirectional torsion rocker arms (8), the speed changing gears (10) and the steering yoke (1) are used, the height can be adjusted according to heights of children of all ages, the pedal supporting positioning plate (15) is arranged at the back of the frame (4), and the children can tread on any pedal at will to move the exercise bicycle, so that the children can operate the exercise bicycle easily, the safety is high, the exercise bicycle can serve as a fitness tool as well as a riding tool, the designed structure is simple, and the manufacturing cost is low.

Description

A kind of stationary bike for children

Technical field

The utility model relates to a kind of body-building vehicle, especially a kind of children's pedal body building vehicle.

Background technology

Health is one of life happiness, and motion is healthy key activities.Cycle racing is not only Olympic medal sport, also has the effect of taking exercises simultaneously.Not only the adult wants body-building, and children want body-building too, and the adult is body-building by bike, but bicycle does not fit into children's body-building.Normal children's fitness equipment is wooden horse, treadmill, dumbbell, and fixes again, and the exercise effect is comprehensive inadequately again.Also have the Hai Zhenjie of Ningbo City to step on (Granted publication CN.202006855U) a kind of bicycle of the red invention of the Chen Zhao of Institute for Applied Technology, its vehicle body is higher, when the car coast, can only steadily stand on the vehicle body by a pin, must closely cooperate by both feet when travelling, there is not the lift in height system, just cause body-building person that passive sensation is arranged, can not arbitraryly operate, safety for children is just not high enough, just cause children to feel dull to taking exercises, do not want to take exercise, feeling to take exercises is a kind of pressure, and children also will not too like body building.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of can riding instead of walk, can take exercises again, and vehicle body is low easy stationary bike for children simple to operate.

The technical scheme that the technical matters that the utility model solves adopts is that a kind of pedal body building vehicle comprises: direction lever 1, lift in height card 2, scored card 3, vehicle frame 4, brake 5, pedal 6, connecting rod 7, unidirectional torsion rocking arm 8, wheel 9, variable gear 10, return spring 11, front fork 12, direction front-wheel 13, step height radius stay 14, pedal supporting locating plate 15.It is characterized in that: described steering wheel 13 is contained in the front fork 12, brake system 5 is housed on the front fork, there is scored card 3 the front fork top, be convenient to take in and carry, lift in height card 2 is arranged above scored card 3, in order to be more suitable for the children of various age bracket height, direction lever 1 is contained in forms direction operating system assembly in the lifting card 2, direction operating system assembly copies bike tech to be connected on the vehicle frame 4, pedal 6 the place aheads are connected on the vehicle frame 4, and return spring 11 is housed, make pedal step down the rear foot mention unclamp pedal can self-return, in order to trample next time.Locator card 14 is arranged on the vehicle frame 4, surely live pedal rise position, pedal 6 rears are connected on the connecting rod 7, connect unidirectional torsion rocking arm 8 through connecting rod again, unidirectional torsion rocking arm 8 is connected on the front axle of variable gear 10, through the shaft driven gear speed change, variable gear 10 is contained in the vehicle frame 4, variable gear 10 drives rear wheel 9 through rear axle, and there is pedal below locating support plate 15 at the vehicle frame rear, lives pedal position when being used for stepping on surely and can not cross low and the supporting human body weight.

Compare with present technology, the advantage of the utility model body-building vehicle is that vehicle body is low, two pedals are connected on respectively on the unidirectional torsion rocking arm, can arbitrarily trample wherein any pedal walking, can steadily stand on the vehicle body by both feet during coast, the direction lever height can be regulated according to children's height, so it is simpler easy to operate, owing to use gear change, so can adorn the speed governing of gear bar again, and more steady when trampling, be especially at a kind of children's exercise bicycle of designed for children.Because children's body weight is lighter, just below the pin center of gravity, car is to walk by the pressure of human body weight to the unidirectional torsion rocking arm of this transmission torsion point, so its power effect is also better.This simplicity of design, cost are low, because this body-building vehicle is the people to be stood in and step on walking on the pedal, so that the pin station the be seated power that steps down of the force rate that steps down is bigger, and the height that this stationary bike for children pedal is trampled designs by the stair height at children.Needn't lift De Taigao to pin when trampling, be more suitable for children's body building, can work as children's walking-replacing tool fully and use, and driven the all-around exercises of human body, reached better body-building effect, owing to adopt the transmission of unidirectional torsion rocking arm, all only can walk forward so arbitrarily trample it.Front fork adopts scored card, is convenient to take in and carries.
