Abstract
The utility model relates to a body building bicycle for children, which is mainly composed of a bicycle frame, a front wheel, a back wheel, handlebars, a folder, pedals, elastic elements, an auxiliary wheel and saddle. The utility model is characterized in that a connection shaft is arranged on each of the pedals of which the rear ends are connected with an axletree, the front end of a connecting rod is hinged with the connection shaft, the rear end of the connecting rod is hinged with an eccentric axle of a gear which is in moveable fit with the bicycle frame, the gear is connected with a free wheel through a chain, the free wheel is connected with the rear wheel, and the elastic elements are arranged between the pedals and the bicycle frame. When children stand on the pedals to perform the motion of upward and downward jumpiness to alternating tread, the pedals overcome the elastic force of the elastic elements to swing up and down, the gear is driven to rotate through the connecting rod, and the bicycle is driven ahead through the chain and the free wheels. The utility model arouses the interests of children in sport, and satisfies the requirement of jumpiness of children.
Description
Affiliated technical field
The utility model relates to a kind of carriage for children or body-building vehicle.
Background technology
At present, the type of drive of the perambulator that children use is the same with bicycle to be driven car by foot-operated, crank, chain, flywheel and advances, and its mode of motion dullness, dull can not satisfy children and like to jump and like the needs of jumping.
Summary of the invention
The purpose of this utility model provides a kind of body building bicycle for children, is used to satisfy children and likes to jump and like the needs of jumping.
The purpose of this utility model is achieved in that a kind of body building bicycle for children of design, mainly is made of vehicle frame, handlebar, front and back wheel, brake gear, pedal, saddle seat, elastic element.It is characterized in that rear end and hind axle pivotally attached pedal, it is hinged that pedal is provided with the front end of adapter shaft and connecting rod, and the rear end of connecting rod is hinged with the eccentric shaft of the gear that is actively tied in vehicle frame, and gear is connected with flywheel by chain, flywheel is connected with rear wheel, is connected with elastic element between pedal and the vehicle frame.When the user stands in pedal and jumps downwards, pedal overcomes the elastic force of elastic element to lower swing, rotates by the connecting rod driven gear, and gear is walked before by the chain drive car: when the user when pedal is upwards jumped, elastic element resets and makes the pedal swing that upwards resets, and this moment, flywheel oppositely dallied; When the user constantly beats on pedal, repeat said process, drive car and go ahead: the user also can alternately step on the pedal drive car with single pin and advance; Improve user's motion interest, satisfy the user and like to jump and like the needs of jumping.
