Description

Bicycle driven by rowing and sliding

Technical field:

The utility model relates to a kind of bicycle device, particularly a kind of sliding driven bicycle of drawing of interesting body-building motion of realizing.

Background technology:

At present, rod-pulling type, crank type tricycle have all become the good assistant of instead of walk for invalids, but this vehicle seats is fixed, thereby can not give full play to the strength of pin and leg.Though and our bicycle with triple wheels driven of before open invention has solved the problems referred to above, just centnifugal force overcomes undesirablely when turning to, and chain drum is had an effect bad.

Summary of the invention:

The utility model is the research of carrying out at the problems referred to above, its objective is that the combination with girder and auxiliary girder replaces original single-spar construction, chain drum with dual-slot structure replaces original single structure chain guard device, replace original straight shape galianconism with long-armed stroke of bar of arc and draw bar, this car is turned steadily, and drawing bar and chain drum can play one's part to the full.

The technical solution adopted in the utility model is:

Employing has the two parallel girder [1] of chair slide, the front portion of girder [1], rear portion connect with front portion, the rear portion of two parallel auxiliary girders [2] respectively, girder [1] front end fixedly is equipped with two-wheeled or takes turns the front vehicle fork of front axle [3], the two-wheel rear axle is equipped with in auxiliary girder [2] rear end, front vehicle fork [3] both sides are equipped with stretcher [4] steering hardware respectively, double flute chain drum [5] actuating device is equipped with in auxiliary girder [2] front portion, and sliding seat [6] is housed on the girder [1]:

Stretcher [4] steering hardware: front vehicle fork [3] upper end is connected with the front end of girder [1], and the lower end is connected with front axle, and steering beam [7] two ends of front vehicle fork [3] are connected with bent axle [8] respectively, and the other end of bent axle [8] is connected with stretcher [4] axle;

Double flute chain drum [5] actuating device: double flute chain drum [5] is equipped with in auxiliary girder [2] front portion, long-armed stroke of bar of arc [9] is equipped with in the both sides of double flute chain drum [5], one end of chain [10] is fixed on the rear end of a groove in the double flute chain drum [5], another side is walked around the guide wheel [12] at girder [1] front end and middle part from bottom to top along this groove, walk around the flywheel [11] on the rear axle more from the top down, oppositely walk around another flywheel [11] from the below by the guide wheel [12] that install at auxiliary girder [2] rear portion, another groove in the double flute chain drum [5] also is fixed on its front end.

Advantage of the present utility model and good effect are:

Owing on this bicycle driven by rowing and sliding, adopt the two parallel girder [1] that chair slide is arranged, the front portion of girder [1], the rear portion respectively with the front portion of two parallel auxiliary girders [2], the rear portion connects, girder [1] front end fixedly is equipped with two-wheeled or takes turns the front vehicle fork of front axle [3], the two-wheel rear axle is equipped with in auxiliary girder [2] rear end, front vehicle fork [3] both sides are equipped with stretcher [4] steering hardware respectively, double flute chain drum [5] actuating device is equipped with in auxiliary girder [2] front portion, the structure of sliding seat [6] is housed on the girder [1], this car seat when turning can be tilted slightly from the trend turn direction, overcome the centnifugal force of vehicle body with this.

Because the stretcher steering hardware of this car adopts front vehicle fork [3] upper end to be connected with the front end of girder [1], the lower end is connected with front axle, steering beam [7] two ends of front vehicle fork [3] are connected with bent axle [8] respectively, the other end of bent axle [8] and stretcher [4] axle bonded assembly structure makes stretcher firmly and can both keep when turning not only flexibly but also stable.

Owing on the chain disk drive device of this car, adopt double flute chain drum [5], can make chain pass through double flute chain drum [5] two flywheels accurate and on the rear axle and be connected; Owing to adopt arc to draw bar, can change the structure of having an effect of drawing bar, adopt (more than 1.2 meters) long-armed stroke of bars [9] structure, can change hand holding a little on long-armed stroke of bar according to the needs of having an effect.

Owing to go up at the girder [1] of this car and to adopt the inner slide structure, the pulley of sliding seat [6] is slided in its groove can not influence the running of other structures.
