Description

Multi-function healthful children bicycle

The utility model relates to the improvement invention of child's bicycle.

The existing child's bicycle that uses, all be to replace the walking pick up speed with bicycle, it all is the simple mode of motion that advances with the pedal car, except child's amusement, though be a kind of exercise to foot's strength of child, on the whole still not enough from the people, as lack the exercise of arm strength, power of waist, adopt chain gear that brake gear need be set simultaneously, very dangerous to begining to learn children, and also the lubricating oil on the chain is easy to child's the bottom of s trouser leg of making dirty.

In view of the deficiencies in the prior art, the purpose of this utility model aims to provide the multifunctional body-building perambulator of a kind of safety, health, collection amusement and body-building one.

The utility model is realized as follows: the utility model comprises vehicle frame (5), front vehicle wheel (1), rear wheel (6) and (10), handlebar (2), stretcher (9), vehicle seat (4), on the vehicle frame (5) between described handlebar (2) and the vehicle seat (4), a bearing support (3) is set, between bearing support (3) and the rear vehicle shaft (15) crank link gear is set.

Above-mentioned crank link gear is formed for the corresponding bent axle (11) that is fixed on driving crank (8), connecting rod (7) and connection connecting rod (7) other end on the bearing support (3) and be fixed on the rear vehicle shaft (15).

It is fastening that cooperation between each above-mentioned major part is fixed as the cooperation of living, and can remove and install mutually.

On above-mentioned front truck wheel shaft and a rear vehicle shaft ratchet stopping device (12), (13) are set respectively.

The utility model compared with prior art, advanced person rational in infrastructure, the multiple mode of motion of one-tenth capable of being combined integrates amusement and body-building, intelligence development, not only safety but also health.

Accompanying drawing has been represented the unitized construction scheme drawing of three kinds of mode of motion in the utility model, elaborates structure of the present utility model and principle and using method in conjunction with these three embodiment more below.

As Fig. 1, shown in 2, the utility model comprises vehicle frame (5), front vehicle wheel (1), rear wheel (6) and (10), handlebar (2), stretcher (9), vehicle seat (4), on the vehicle frame (5) between described handlebar (2) and the vehicle seat (4), a bearing support (3) is set, and bearing support (3) is fixed on the vehicle frame (5) with fastener, between bearing support (3) and rear vehicle shaft (15), crank linkage driving system is set, described crank linkage driving system is a pair of driving crank (8) that is fixed on the bearing support (3), the connecting rod (7) and connection connecting rod (7) other end and the corresponding bent axle (11) that is fixed on the rear vehicle shaft (15) are formed, described bent axle is 90 ° of bent axles, on front truck wheel shaft and a rear vehicle shaft, a ratchet stopping device (12) is set respectively, (13), described stretcher (9) is installed on the driving crank (8), installs and fixes two isometric connecting rods (7) between driving crank (8) and bent axle (11).When external force acts on when making circular movement on the stretcher (9), bent axle (8) is also made circular movement, drives two connecting rods (7) and passes to back bent axle (11), causes rear wheel to roll to the previous crops circumference, thereby realize that bicycle travels forward the above-mentioned bicycle motion process that is.Adopt this aggregate erection structure, can temper foot's strength of child.

Shown in Fig. 3,4, on architecture basics shown in Fig. 1,2, to connect driving crank (8) pulls down with two long connecting rods such as grade (7) of back bent axle (11), and bent axle (8) initiatively is fixed on the bearing support (3) with fastener, make it and to rotate, unloading stretcher (9) then is installed on the front wheel spindle, simultaneously handlebar (2) is stuck to extract out to assign in the past and be fixed on bearing support (3) upper end and tighten up, join a connecting rod (14) in addition between crank (8) and bent axle (11), dismantling is fixed on set screw on bearing support (3) and the vehicle frame (5).Go up waggle when external force acts on handgrip (2), drive the driving crank (8) that is installed on the bearing support (3) and move together with connecting rod (14) and pass to back bent axle (11) and make circular movement, travel forward as circumference thereby drive wheel.Adopt this aggregate erection structure, can temper child's arm strength.

Shown in Fig. 5,6, on the basis of structure shown in Fig. 3,4, the connecting rod (14) that connects two bent axles is dismantled, bearing support (3) and vehicle frame (5) are taken apart, then rear vehicle shaft support (16) is assigned to be fixed in the bearing support (3), and fixed with fastener.When kicking outside drawing in the direction that acts on the last power of handgrip (2) and stretcher (9) is, front-wheel (1) is motionless, advances in trailing wheel (6) and (10), and vehicle seat (4) rises simultaneously; In the time receiving in outer forced direction is extrapolation, trailing wheel (6) and (10) are motionless, and front-wheel (1) advances, and make vehicle seat (4) reduction.Adopt the aggregate erection structure of above-mentioned this plug-type motion, can temper the muscle strength of multi-section positions such as hand, arm, foot and waist simultaneously.

The utility model is by the elaboration of above-mentioned three kinds of embodiment, embody the utility model and integrate amusement and body-building multi-function action and safe and reliable, very advantageously developing child's intelligence and cultivate manipulative ability and extensive interest with easy various fast assembling-disassembling variation simultaneously, is that one of current perambulator is improved innovation greatly.
