Description

The all-around exercises body-building vehicle

The utility model relates to the bicycle that a kind of manpower drives all-around exercises.

Existing trick drive the body building car be a kind ofly integrate body-building, ride instead of walk, the multifunctional body-building sporting car of amusement, it is to adopt the work done mode of using both hands and feet, embodied the aesthetic feeling of human motion, harmony is good, safety and comfort, in the process of riding, arm, tendon pin and waist can both comprehensively be taken exercise.Above-mentioned trick drives the body building car and structurally exists following shortcoming: the structure of first vehicle frame is comparatively complicated mostly; It two is that steering swivel system is installed and adjusted all very difficult; It three is to use common vehicle seat, and can not overcome effectively moves simultaneously because of trick makes human body produce the problem of slippage forward.

The purpose of this utility model is to provide a kind of all-around exercises body-building vehicle of the steering swivel system that has simple body frame structure for automotive and be simple and easy to adjust.

The utility model is made up of front-wheel 17, trailing wheel 10, main car frame 21, arm, legs and feet drive system, steering swivel system and brake system.Described vehicle frame 21 front ends are equipped with front fork 18, and front-wheel 17 is installed on the front fork 18, and rear drive sprocket 8 is equipped with at vehicle frame 21 rear portions; Arm, legs and feet drive system are equipped with in vehicle frame 21 middle parts.It is characterized in that: main car frame 21 is two steel pipe twin-spar constructions that side direction is linearly, and main car frame 21 middle parts are provided with axis chain drum 12; The hand lever 3 lower end jags of manual system, hand lever 3 is fixed on the main car frame between chain drum 12 and the front fork 18 by rotating shaft; On the main car frame between above-mentioned hand lever 3 and the front fork 18, by rotating shaft open two symmetrical foot-driven levers 16 downwards are installed, foot-driven lever 16 links to each other by a connecting rod 14 with the jag front end of hand lever 3 lower ends, and the crank 11 on jag rear portion and the sprocket wheel is by 13 connections mutually of another connecting rod.

A pulley 2 is housed on the top of above-mentioned hand lever 3, and pulley 2 interconnects by rotating shaft with hand lever 3 tops, and described pulley 2 is connected with handgrip 23, and can rotate thereupon; A fastening take-up device of Fu is with it arranged on pulley 2 tops, described fastening take-up device comprises: eye bolt 24, a clamp nut 26, a tightening nut 25, the steel wire 20 in the clamp nut 26 clamping bolt holes, tightening nut 25 lift steel wire 20 and it are fixed on the handgrip frame 27; Steel rope 20 is 3 downward from the pulley side grooves along hand lever, turnover position, steel rope 20 middle parts is the hollow tube 4 that fixing middle part, two two ends intersects, described steel rope 20 passes hollow tube 4 respectively, and before turning to, place in the groove of the rotary pulley 19 on the front fork, and be fastened in the pulley grooves, described steel rope 20 is fricton-tight linking to each other with described two rotary pulleys.

Swing seat bar 5 also is housed on main car frame 21 tops, on the swing seat bar 5 beloid saddle shape vehicle seat 6 is housed, two damping compression springs 7 are housed between vehicle seat 6 belows and the main car frame.

On described rear vehicle shaft brake disc is housed, front-wheel is equipped with pincerlike brake.

The utility model is compared with traditional trick driving body-building vehicle, has following advantage:

1. main car frame is simple in structure;

2. the rotation system dependable performance is easy to install, adjust;

3. the saddle shape vehicle seat can prevent the slippage forward that the human body on the go produces effectively.
