Abstract
The utility model discloses a body-building bicycle which is composed of a main frame, a front outer tube, a cushion branch pipe, a driving tube, a chain, an elastic soft cable, a front wheel, a back wheel, a handle, and a pedal plate. 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 end is pivoted with the driving tube. The back part of the main frame is fixedly provided with a positioning post, a fixed axis, and is pivoted with a guide tube. The positioning post is connected with the elastic soft cable. The fixed axis is provided with a movable pulley. The guide pipe and the driving tube are in sleeve joint. One end of the elastic soft cable is connected with the positioning post, and the other end is connected with one end of the chain. The chain passes round a fly reel and the movable pulley, and the other end is fixed at the lower end of the driving tube. The human body can make the driving tube exert force to the chain by the rhythmic heave motion on the bicycle through depending on the self gravity. Therefore, the wheel is drove to advance by the transmission fly reel. The utility model realizes the design goal of good body-building effect, strong interest, and strong security and stability.
Description
Technical field
The utility model relates to a kind of 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 body-building bicycle of human abdomen and shank simultaneously.
In order to achieve the above object, the utility model by the following technical solutions: a kind of body-building bicycle, this structure mainly are made up of body frame, preceding outer tube, cushion arm, driving tube, chain, the soft rope of elasticity, cushion, front-wheel, trailing wheel, handle and stretcher; The body frame front end is captiveed joint with preceding outer tube, and 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; The body frame rear portion is installed with a registration mast, a back vent, an anchor shaft and is pivoted with a guide pipe, and registration mast connects an end of the soft rope of elasticity, and back vent is in order to set up trailing wheel, and anchor shaft is provided with sliding wheel, and guide pipe and driving tube socket-connect; The wheel shaft of trailing wheel is provided with flywheel; One end of the soft rope of elasticity is connected in registration mast, and the other end is connected with chain; Chain one end is connected with the soft rope of elasticity, walks around flywheel, sliding wheel then successively, and the other end is fixed in the lower end of driving tube.
The appropriate location, middle part of described body frame is installed with stretcher downwards.
Afterbody lower end captive joint one axostylus axostyle of described cushion arm, the movable driving tube that articulates of axostylus axostyle.
