Abstract

The utility model discloses an on-horseback type body-building bicycle which is composed of a main frame, a front outer tube, a cushion branch pipe, a driving tube, a transmission system, a cushion, a front wheel, a back wheel, a handle, and a pedal plate. The front end of the main frame is fixedly connected with the front outer tube. The front outer tube is pivoted with the cushion branch pipe. The proper position between the cushion branch pipe and the main frame is respectively pivoted with a damper. The upper end of the tail part of the cushion branch pipe is fixedly connected with the cushion, and the lower part is pivoted with the driving tube. The lower end of the driving tube is pivoted with a hook handle on a chain dish. The tail end of the main frame is downward fixedly provided with a rear fork to support the back wheel. The wheel shaft of the back wheel is provided with a fly reel. The hook handle drives wheel shaft by the transmission system. The proper position in the middle of the main frame is provided with the pedal plate. The human body makes the driving tube exert force to hook the handle by the rhythmic heave motion through depending on the self gravity. Therefore, the wheel is drove to advance by the transmission system. The utility model realizes the design goal of good body-building effect, strong interest, strong security and stability.

Description

The horseback riding type body-building bicycle

Technical field

The utility model relates to a kind of body-building bicycle, relates in particular to a kind of horseback riding type body-building bicycle.

Background technology

The body-building bicycle structure of prior art is divided into two kinds mostly, and a kind of is the body-building stationary bicycle that scrunches about human body, and the defective of this body-building bicycle is: move singlely, body-building vehicle can not move ahead, and interest is not strong, and human body is tired easily; Thereby another kind of structure is a human body steps on to jump on pedal and can drive body-building vehicle and move ahead, the defective of this body-building bicycle is: the mode with unsettled jump drives, the bad grasp of gravity center of human body, balance is bad, personal injury more easily takes place, and this mode is the same with the body-building stationary bicycle mainly can only temper the human body shank.

The utility model content

The purpose of this utility model is in order to overcome the deficiencies in the prior art, but provides that a kind of interest is strong, human motion smooth drive bicycle moves ahead, human body indefatigability and can temper the horseback riding type body-building bicycle of human abdomen and shank simultaneously.

In order to achieve the above object, the utility model is by the following technical solutions: a kind of horseback riding type body-building bicycle, this structure is mainly by body frame, preceding outer tube, the cushion arm, driving tube, driving system, cushion, front-wheel, trailing wheel, handle and stretcher are formed, the body frame front end is captiveed joint with preceding outer tube, preceding outer tube articulates the cushion arm, relative pivot joint one Shock absorber of cushion arm with the appropriate location between the body frame, cushion arm afterbody upper end captive joint cushion, the lower end articulates driving tube, collude handle on the driving tube lower ending pivot chain link dish, the body frame tail end is installed with back vent downwards, in order to set up trailing wheel, the wheel shaft of trailing wheel is provided with flywheel, colludes handle by the driving system power axle, and appropriate location, body frame middle part is to having stretcher.

Described driving system is the four-wheel transmission, and promptly a side pipe appropriate location of back vent is provided with two arms, articulates a chain drum and a big or small chain drum group of rotating synchronously respectively, and big chain plate is connected with flywheel by chain, and little chain drum is connected with chain drum by chain.

Described driving system is the two-wheeled transmission, and promptly flywheel directly is connected with chain drum by a chain.

Described driving system is the transmission of many wheels, passes through the engagement system transmission between flywheel and chain drum.
