Description
The utility model relates to a kind of perambulator, relates to a kind of four-wheel-type Pedal pram specifically.
The perambulator of prior art has varied, and as the early stage shaft type f-w-d toy tricycle that turns, the trailing wheel of Xing Qiing had the sprocket-type two-wheeled cycle of lateral support wheel etc. in recent years.But its safety is all reliable not as four-wheeled, and roll-over accident especially very easily takes place for the younger ones in an age group children.
The purpose of this utility model is just at above-mentioned existing in prior technology problem, and a kind of strong imitative automobile type four-wheel-type Pedal pram rational in infrastructure, safe, interesting is provided.
The purpose of this utility model can adopt following measure to realize:
Four-wheel-type Pedal pram of the present utility model comprises the vehicle frame that four wheels are installed, steering wheel type foresteerage gear, the driver train of being made up of sprocket wheel, chain, flywheel, and stop mechanism; Sprocket shaft in the described driver train combines with vehicle frame by the bearing seat that is installed on the side bar of the vehicle frame left and right sides, described sprocket wheel is installed in an external part of sprocket shaft, the pedal that is used for drive sprocket axle is arranged on the left and right sides of sprocket shaft midperpendicalar, and every side all is equipped with a pair of pedal in symmetrically arranged mode, two pairs of pedals of the left and right sides are with cross frame mode and are installed in (promptly when a pair of pedal in left side was horizontal, a pair of pedal on right side was in plumbness just) on the sprocket shaft.
Every pair of pedal described in the utility model all is to be made of the U type pedal frame that is symmetricly set on both sides, sprocket shaft axis; Described pedal also can adopt the pedal type structure.
For guaranteeing the safe reliability of brake, simultaneously also be interest and the curiosity in order to cause children, the utility model is designed to stop mechanism by being installed in the formula brake lever of contacting to earth on the vehicle frame by hinge, being connected the extension spring between brake lever and vehicle frame and forming by the stretcher that rod member combines with brake lever; And driver seat is designed to case structure, and its loam cake is the seat face, the casing of seat face below is that toy holds case, and in the front portion of vehicle frame one basketry is installed also, can be used for holding article.
Because the utility model adopts the four-wheel structure of imitative automobile type wheel steering, make this perambulator not only have and turn to flexible, the steadily safe and reliable advantage of riding, also, the utility model replaces crank pedal formula structure owing to having adopted the cross chain link of waterwheel modelled after an antique to pedal structure, changing the motion of riding of traditional circumference moves for stepping type, not only can cause children interest, satisfy its curiosity, simultaneously also kept bigger space for bicyclist's underfooting.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
1 is basketry among the figure, the 2nd, and steering wheel type foresteerage gear, the 3rd, pedal, the 4th, chain, the 5th, seat, the 6th, wheel, the 7th, the formula of contacting to earth brake lever, the 8th, extension spring, the 9th, stretcher, the 10th, vehicle frame, the 11st, sprocket shaft, the 12nd, sprocket wheel, the 13rd, flywheel.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
