Abstract
Currently, small bicycles with auxiliary wheels for children are very popular, children not only can learn to ride the bicycles easily but also can ride safely, and therefore the bicycles have become articles for children for both entertainment and physical exercises. However, when children grow up gradually and are very skilled at riding the small bicycles with four wheels, the children would like to practise riding real double-wheeled bicycles. The utility model aims to provide a bicycle with movable auxiliary wheels for children, the auxiliary wheels can be placed down or lifted up, and thus the bicycle can achieve the three functions including entertainment, exercise and transportation. According to the technical scheme, axle ends on the two sides of a rear wheel of the bicycle are respectively provided wit an independent bracket with one movable auxiliary wheel, each bracket comprises a fixed frame and a movable frame, the fixed frames of the brackets are fastened to the rear axle ends of the bicycle, and the movable frames and the fixed frames are adjusted and fastened through butterfly-shaped screw rods.
Description
Technical field
The present invention relates to individual, household supplies.
Background technology
Existing children are very universal with the little bicycle of auxiliary wheel, and it is easy to learn and safety not only, therefore become existing articles for children recreational, that can take exercises again.
But when children grow up gradually, when the little bicycle of this four-wheel is also ridden very skillfully, just want to dismantle or move this two auxiliary wheels, real bicycle is ridden in exercise, and exercise must have individual process, and ride two-wheel car and can only ride to such an extent that comparatively fast just easily grasp balance, if while wanting to recover to ride four-wheeled after exercise or game slow or that the stop state etc. of playing, very difficult.Therefore the movable auxiliary wheel bicycle of this band can solve the unconformable problem of former auxiliary wheel, make it to keep former quadricycle purposes, has increased again the function that bicycle is ridden in convenience exercise.
Summary of the invention
The purpose of this utility model is to provide a kind of children and is with movable auxiliary wheel bicycle, and this auxiliary wheel both can put down, and also can lift, and realizes amusement, exercise, the three-in-one function of traffic.Its technical scheme is: at bicycle rear both sides spindle nose, each increases by one, and independently with the support of auxiliary wheel, this support is comprised of four parts, and one is arranged on the auxiliary wheel fixed mount of fastening nuts for bicycle rear spindle nose; Its two, the auxiliary wheel tressel being rotatably riveted together with rivet with fixed mount; Its three, fly-headed bolt, for fastening fixed mount and tressel; Its four, the auxiliary wheel of installing on tressel.
