Abstract
The utility model relates to an accelerating body-building device like a bicycle, comprising a saddle, a universal joint, a connecting rod, a chainwheel and a fixing plate. The utility model is characterized in that the utility model also comprises a connecting hinge, wherein, the saddle can swing up and down; the length of the connecting rod can be regulated; the saddle is connected with the connecting rod by the universal joint; a bolt at the lower end of the connecting rod is connected with an outer sleeve of a bearing by the hinge; the bearing is fixed on an eccentric shaft of the chainwheel whose centre is provided with the bearing which is fixed on a small shaft at the upper end of a fixed plate whose lower end is welded on a bottom beam in the middle of a bicycle chain; thus the chainwheel is engaged with the chain.
Description
The utility model relates to a kind of bicycle speedup fitness equipment.
Existing bicycle does not have to utilize the speedup system of cyclist's body weight as power, and the purpose of this utility model provides a kind of economical and practical, can actv. utilizes the speedup body-building system of cyclist's upper body weight.
For realizing above purpose, the utility model is taked following design: bicycle speedup fitness equipment, it comprises saddle, universal-joint, connecting rod, sprocket wheel, adapter plate, it is characterized in that: it also comprises connecting hinge.Described saddle is divided into seat cushion and chassis two parts, respectively is welded with two strut bars, and middle with the hinge connection, seat cushion can swing up and down.Seat cushion bottom one face down bonding has between a strut bar and the connecting rod and is connected by universal-joint, connecting rod is provided with bolt, can regulate length, terminal and the bearing outside hinge-coupled of bolt, bearing fixing is on the eccentric shaft of sprocket wheel, and centre of sprocket is provided with bearing, is fixed on the little axle of adapter plate upper end, the adapter plate lower end is welded on the middle bottom girder of cycle chain, makes sprocket wheel and chain interlock.
The utility model utilizes cyclist's weight itself to be power, can improve the gait of march of bicycle effectively.Because saddle swings up and down, cyclist's upper body exercises and leg exercise can be harmonious, make the cyclist eliminate upper body fatigue, build up health, and the utility model is widely used on the various bicycles.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the schematic side view of Fig. 1
Fig. 3 is a saddle chassis structure scheme drawing
Fig. 4 is the adapter plate structural representation
Saddle is divided into seat cushion 1 and chassis 2 two parts as shown in Figure 1 and Figure 2, the rear and front end respectively is welded with two strut bars, between the strut bar by hinge 3, hinge 4 connects, seat cushion one face down bonding has strut bar 5 to be connected by universal-joint 6 with connecting rod 7, regulating bolt 8 cooperates with connecting rod 7, can regulate length, bolt 8 ends are connected by hinge 9 with bearing outside 10, bearing fixing is on eccentric shaft 15, sprocket wheel 12 centers are provided with bearing fixing on the little axle 14 of adapter plate 13 upper ends, and adapter plate 13 lower ends are welded on the middle bottom girder of cycle chain, make sprocket wheel and chain interlock.
Sprocket wheel during installation in the utility model and bicycle chainwheel rotation direction are harmonious, and seat cushion swings up and down, and drivening rod, connecting rod move in a circle sprocket wheel, drive cycle chain.
