detailed description:

Referring to Fig. 1 to Fig. 4, these 4 accompanying drawings provide the structural diagram of an embodiment of the pedal swing type recreational exercise bike proposed by the utility model. The exercise bike comprises a vehicle frame, a front bracket, a rear suspension, a pedal device, a ratchet mechanism, a transmission system, a braking device, a folding device, front and rear wheels, etc., and its specific structural features are: the left and right pedals (11) pass through The pin shaft and the torsion spring (13) are installed on the front end of the vehicle frame (9), the transition link (12) and the rocking bar (43) are hinged below the pedal (11), and are connected to each other through a hinged form, and one end of the rocking bar (43) passes through The rolling bearing (44) is installed on the ratchet shaft (24), and can swing around the ratchet shaft (24). The ratchet (50) is connected to the other end of the rocking bar (43) through a pin and a return spring (48), and the ratchet (42) passes through The key connection is installed on the ratchet shaft (24); the transmission system is composed of two-stage cylindrical spur gear transmission and a first-stage chain transmission, and the gear (51) is installed on the ratchet shaft (24) through a key connection, and the gears (26) and (40 ) is installed on the intermediate shaft (29) through a key connection, the large sprocket (38) is installed on the sprocket shaft (31) through a key connection, and the small sprocket is installed on the rear wheel hub (34); (28) support, the bearing is installed in the bearing seat (25), and the bearing seat (25) is fixed on both sides of the vehicle frame (9) through bolt connection; the front and rear wheels (18, 1) are installed through the hub (21, 34) On the front and rear wheel axles (22, 35), the rear wheel axle (35) is installed on the rear suspension (4), and the two ends are tightened and fixed by nuts, and the rear suspension (4) is fixed on the rear of the vehicle frame (9) by bolts.
