Description

Body-building entertainment tetracycle for children

The utility model relates to bicycle, particularly juvenile's body-building recreation bicycle.

At present, the juvenile drives type toy roughly hand barrow, bicycle, slide plate etc., and Bicycle is commonplace, and Applicable scope is very wide, but too common; The slide plate type toy has thrill, recreational good characteristics, but the operative technique that its requires is than higher, and children below 10 years old are difficult to grasp its operation skill, yet, still there is not a kind of juvenile's recreational vehicle that has both bicycle and slide plate characteristics, satisfy people's demand widely.

The purpose of this utility model provides a kind of juvenile of being suitable for and steps, convenient and flexible operation, and the bicycle of collection bicycle and slide plate characteristics to increase recreational and to temper juvenile's balanced capacity, capability of reaction, reaches the purpose that improves the health.

The utility model comprises bent axle 1, stretcher 2 and connecting panel 3 etc., and the place is fixed on the connecting panel 3 in the middle of the bent axle 1 that connects one in opposite directions to it is characterized in that staggering two U-shaped integral body, and bent axle 1 recess is fixed on the stretcher 2, and bent axle 1 two ends connect wheel 4.

When using bicycle, bipod steps down on the pedal, alternately steps on up and down, and dolly just can travel forward; Oppositely step on backward, but the dolly backward; When needing to turn, as long as rear heel is exerted all one's effort slightly, the dolly front-wheel can lift slightly, utilizes the twisting of health, can make dolly turn over an angle, and preceding tiptoe one is exerted oneself again, and front-wheel lands, and finishes turning action.The artificial fully control of the speed of travel of dolly is stepped on frequently, and walking is fast, does not step on, does not walk.

The utility model design is feasible, rational in infrastructure, making is easy, easy and simple to handle, has bicycle and slide plate function concurrently, integrates entertainment body-building, can temper juvenile's balanced capacity and capability of reaction, interesting strong, the children that are suitable for 5-15 year use, and are suitable for to popularize.

The utility model Fig. 1 is a structural representation, and Fig. 2 is bent axle and pedal connection structure cutaway view; Fig. 3 is the crankshaft structure scheme drawing, and Fig. 4 is wheel and bent axle connection structure cutaway view, wherein, and bent axle 1, stretcher 2, connecting panel 3, wheel 4, axle sleeve 5, baffle plate 6, pin 7, cap 8.

The utility model is the bicycle that is applicable to that 5-15 year children use, and the bent axle bending part adopts and is slightly larger than 90 ° of (100 °) bent angles, advantage one be pressing mold be shaped easily when being shaped, pull out touch convenient and tooling cost low; The 2nd, greater than 90 ° of bent angles, scratching can not take place in bent axle and connecting panel, stretcher; Bent axle and stretcher place adopt nylon jacket that nearly 1/4 circle lacks as axle sleeve, utilize the elasticity of breach nylon jacket, and it is very convenient that it is snapped fitted on the bent axle assembling; Wheel and bent axle connection structure are to pass bent axle to bore half open-work in the support of wheel, the pin of packing into, and the stifled cap of going up makes wheel axial and circumferential location with pin, and locations be can't see in the outside, makes compact conformation, attractive in appearance.
