Description

A kind of body-building tricycle

Technical field

The present invention relates to field of vehicles, in particular to a kind of body-building tricycle.

Background technique

Tricycle abbreviation tricycle is the vehicles made of one kind is transformed as bicycle, manned can transport Goods；Each component part of traditional tricycle, vehicle frame is all fixed together, and tricycle will walk, and lean on completely is that manpower scrunches Foot pedal drives crank to drive central axis again by foot pedal, so that rear wheel is driven by the sprocket wheel on axis, thus Entire tricycle is set to travel forward, so that tricycle only has manned loading function, that is to say, that entire stroke only leans on leg Portion's strength lacks body-building function；And the length of crank is fixed and invariable, and length is unable to adjust, and the time ridden is long, fatigue Sense increases, and affects riding speed；In addition, road is restricted driving railing everywhere now, there are also many narrow road, if two rear-wheels Spacing is unalterable, and some places can pass through difficulty.

Summary of the invention

In order to compensate for the shortcomings of the prior art, the present invention provides a kind of body-building tricycles for having both body-building function.

The present invention is achieved through the following technical solutions:

A kind of body-building tricycle, including front-wheel, two rear-wheels, handlebar beam barrel, axis, axis connecting crank, axis are located at In middle beam barrel, pass through rear axis connection between two rear-wheels, characterized in that main car frame, the main vehicle are installed on the middle beam barrel The front end of frame is hinged on the lower end of handlebar beam barrel, and the crank includes inside crank and outside crank, leads between outside crank and inside crank Connection axis connection is crossed, push-pull rod is wherein hinged in the connecting shaft of side, the front end of the push-pull rod is hinged on handlebar beam barrel；

The rear axle includes jackshaft, and the both ends of the jackshaft are respectively a roll adjustment sleeve, the roll adjustment sleeve other end For roll adjustment axis, the rear-wheel is arranged on roll adjustment axis.

The outside crank is stretching structure, it is including adjusting housing and adjusting interior bar, the adjusting housing and adjusting interior bar Between pass through adjusting screw nail connection.

The cross section for adjusting housing and adjusting interior bar is all rectangular.

The push-pull rod is threadedly coupled by preceding end link, adjusting silk cylinder and rear end link, adjusting silk cylinder both ends Screw it is contrary.

It further include oblique vehicle frame, the oblique vehicle frame is equipped with lateral spare fixing bolt and fixture nut；The adjusting silk Tube rear end is provided with and can pass through the fixation hole of spare fixing bolt.

The front-wheel is less than rear-wheel.

The axis is equipped with backup flywheel, and the backup flywheel is fixed together with inside crank, the handlebar beam barrel two Side is installed with otic placode backward respectively, passes through otic placode axis connection between two pieces of otic placodes, otic placode axis one end is fixed with Spare chain drum, is equipped with spare chain between the spare chain drum and backup flywheel, the main car frame is hinged on otic placode axis.

The handlebar beam barrel is equipped with the gag lever post towards oblique vehicle frame.

The beneficial effects of the present invention are:

In ride, by the handlebar that rocks back and forth, drives connecting shaft to do circumferential movement by push-pull rod, foot pedals are played Power-assisted effect, realizes hands-feet double-action power drive, not only saves strength, but also tempered upper limb, enhance upper limbs force；Push-pull rod The conversion from hands-feet double-action power to the single-power of only foot motion is realized in the setting of detachable structure and spare fixing bolt. The configuration of the present invention is simple can not only be used for common tricycle and use, can be used with body-building, and can temper upper limb, moreover it is possible to forge Refine lower limb；Also adapt to the road of different width.
