Description

Safety gymnastic wheeled vehicle operated by foot

The utility model relates to a kind of as the physical training apparatus, the wheeled car that the person of taking advantage of drives, particularly a kind of pedal-type fitness bicycle.

The body-building vehicle of Chu Xianing is the physical health exercise apparatus that a class has amusement function concurrently in recent years.Utility application 88217282.4 discloses a kind of tread-on-wave type massaging and body-building car, it is to be made of pedal, massage cushion, wheel, bent axle and crankshaft base, be characterized in to rotate mutually after bent axle and wheel disk fasten, bent axle then is that running-fit is connected with crankshaft base, and the person of taking advantage of steps down on the pedal and to form tread-on-wave type and advance.Its defective has been to use the bent axle of steel.Obviously, the manufacturing of bent axle is installed, and is not easy, and is higher to its precision and rigidity requirement, has distortion will cause its operation mal slightly.Utility application 90201506.0 disclosed another kind of pedal-type fitness bicycles have avoided using the defective of bent axle, and its uses straight square head shaft to replace bent axle, is fastened on the eccentric position of wheel.The person of taking advantage of stands on two pedals, and both feet are exerted oneself equably, tramples up and down and lifts, and car load is walked free to advance or retreatly.But working as the player is old children or beginner, and time can fall to falling down owing to stepping on suddenly, and the anxiety of safety is inadequately arranged, and safety performance is relatively poor.The square toes axle head of this car is packed into behind the logical square hole of wheel, inserts with a round end cotter pilotage in the flat groove of square toes end, makes two bead distendings of flat groove, blocks wheel hole outer wall, and reaches flush fit.But this fit can only be adorned and can not tear open, as axle misloading another logical square hole to wheel, has only axle is destroyed, and begins to such an extent that draw off.Therefore, this car can only assemble just and can dispatch from the factory by car load, all feels inconvenience for transportation, buyer, has limited its production in enormous quantities, transportation and use widely at a distance.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of multi-functional pedal body building vehicle with insurance, recovery function, the dismounting of assembly unit freely is provided.

The purpose of this utility model can reach by following measure:

The utility model body-building vehicle comprises pedal (1), wheel (2), square head shaft (3), stop pin (5), power-assisted rod (6).Detouchable screw fit is all adopted in connection between above-mentioned each parts.Two logical square holes (7,7 ') are set to eccentric symmetrical parallel on the wheel, the square toes end of square head shaft covers a packing ring that the periphery is bigger than the hole after inserting logical square hole on the opposite side axle head of hole, pass packing ring with thread cutting screw again, screw in the negative thread at axle center, axle and wheel are fastenedly connected.Six identical wheels respectively before and after, be arranged on three the vertical straight lines in left, center, right, four square head shafts are divided into two groups (pedals of every group of supporting) laterally arrangement in parallel, vertical with the wheel plane, after its square toes end inserts corresponding logical square hole respectively, by last method with packing ring and screw make its fastening it.Two wheelbases in every group front and back are from equating that two logical square holes of middle row's wheel are inserted in the square toes end of right two axles of a first from left respectively from both sides.Like this, two axles of one group go to when the next with wheel, and two axles of another group then are in upper, and axle joins together with wheel, becomes the wheel support that has of a similar carriage underframe.Two pedals with the half slot (8) of its bottom respectively frame install to the other semi-surface of every group of square head shaft stage casing circular shaft, respectively eight halfliners (4) are fixed at the bottom of the plate with screw on.Like this, half slot and halfliner are formed bearing seat, and circular shaft can freely rotate therein.Perhaps, every on four axles are assembled to the pedal bottom by two bearing seats on being fixed at the bottom of the plate.The car of Zu Chenging can use thus.Along with the rotation of wheel, two pedals are one in front and one in back or one high and one low position.

At this moment, each wheel in two outsides has only logical square hole to be with square head shaft.Two another logical square holes that preceding foreign steamer is vacated, can be used for installing two removable power-assisted rods (6), that is to connect plunger (9) by one section, it is prominent the collar of (10) (11) to connect a band, again the lower end of power-assisted rod is entangled prominent, couple together with wheel, handle is made in the upper end of rod.Fastening after loading onto can adopt screw to add the mode of packing ring equally, promptly covers peripheral packing ring greater than the hole respectively at the two ends of plunger (9), passes packing ring with screw again, screw in the plunger center fixation it.

Forward and backward two ends stop pin of also available screw fit on (5) (unloaded screw and can unload the stop pin) in the pedal bottom, when pedal is in low level, overhead 1 centimetre high of this foot, no matter pedal tilts forward or backward, the stop pin promptly lands, and the braking car makes that the treader is unlikely to be fallen down, add two power-assisted rods at hand, the beginner also can play this body-building vehicle safely steadily.

When square head shaft adopts the engineering plastics injection mo(u)lding, for improving the intensity of axle, can inlay the elongated steel pipe (12) of an into reinforcement at the axle center, at this moment, attack negative thread in advance at the two ends of steel pipe, so that when assembling, screw (13) passes in the negative thread that packing ring (14) screws in steel pipe, and axle is connected with wheel securely.

The utility model has following advantage compared to existing technology:

1, freely installs and removes.Connection between each parts of the utility model body-building vehicle all adopts screw fastening, simplifies parts, assembly unit is easy, easy to use.Axially connecting is directly to be inserted in, and adopts the mode of only drawing packing ring to add screw fastening, to prevent axial disengaging, both assembled firmly, convenient disassembly is more convenient for tearing open zero packaging product again, greatly reduce institute and take up space, Packing Fee is 1/2 of a car load packing, is convenient to remote transportation.

2, safety, steady, insurance, reliable.The axle center embeds steel pipe, is strengthened, and is safer.Load onto stop pin and power-assisted rod, the person of taking advantage of also increases the sense of security.Old children is sick and weak to hold double stick with the beginner, will be self-taught, tilt accidentally when trampling, and also can brake immediately, prevent to fall down, exempt from but trouble and worry.Even septuagenarian old man also met with and thought it, is eager to have a try over sixty years of age; Gone up in case play, will be of intense interest, desire to stop endlessly, play the effect of this car amusement of performance, body-building function.In addition, unload above-mentioned two parts, what can be suitable for again that the youngster likes stand-typely steps on the car recreation.Suitable for all ages just, to the satisfaction of all, adapted to the experienced body or the recreation requirement of different levels.

3, tool recovery function.Even leg has the handicapped person, also can play this car, he can use the sitting posture playing method, with the hand propelled rod, drags wheel by rod, and to pedal, the pin that is seated is put on the plate, and pedal rises and falls, and makes both legs be able to activity, promotes the rehabilitation of waist leg.To health care and disease cure, of great advantage, according to the experience of qi-gong practitioner practice, can obtain stimulation to Pelma acupuncture points from body-building vehicle, can combine with doing exercises, residence is practiced the effect of body, health, fitness, fat-reducing, civilization, intelligence development.
