The utility model has the advantages that:
because the first damping device is arranged between the first reinforcing rod and the second damping device is arranged between the oblique cross beam and the oblique vertical beam, when a bicycle is ridden to a bumpy road section by a person, the first damping spring is compressed by the matching relation between the backseat and the oblique vertical beam, the second damping spring is compressed by the matching relation between the saddle vertical rod, the oblique vertical beam and the rear axle fork frame, and the impact force of the bicycle from the ground is resisted through the deformation of the first damping spring and the second damping spring, so that the impact from the road surface can be effectively buffered, and the comfort level and the safety of the person are improved; meanwhile, the pedal plate is convenient for people to tread, the handrail is convenient for people to hold under the action of the handrail rod, and the comfort level of people is improved under the action of the spongy cushion.
Drawings
Fig. 1 is a schematic view of the structure of the present invention.
In the figure: 1. the bicycle comprises a saddle vertical rod, 2 parts of a middle shaft sleeve, 3 parts of a front fork sleeve, 4 parts of a diagonal beam, 5 parts of a diagonal vertical rod, 6 parts of a rear shaft upper rod, 7 parts of a rear shaft lower rod, 8 parts of a rear shaft tail hook, 9 parts of a rear seat, 10 parts of a first reinforcing rod, 11 parts of a second reinforcing rod, 12 parts of a first damping spring, 13 parts of a supporting rod, 14 parts of a pedal, 15 parts of a hand holding rod, 16 parts of a spongy cushion and 17 parts of a second damping spring.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the drawing, a make things convenient for manned bicycle frame, including front fork sleeve 3, saddle pole setting 1, well axle sleeve pipe 2 and rear axle yoke, be equipped with oblique crossbeam 4 between front fork sleeve 3 and the well axle sleeve pipe 2, be equipped with oblique upright beam 5 between saddle pole setting 1 and the oblique crossbeam 4, the one end that oblique crossbeam 4 was kept away from to oblique upright beam 5 is equipped with and erects 5 welded backseat 9 with oblique, the other end of oblique upright beam 5 is articulated with oblique crossbeam 4, rear axle yoke includes rear axle upper boom 6 and rear axle lower beam 7, rear axle upper boom 6 is articulated with oblique upright beam 5, rear axle lower beam 7 is articulated with oblique crossbeam 4, the tail end of rear axle crotch is equipped with rear axle tail hook 8, the bilateral symmetry of rear seat 9 and rear axle upper boom 6 is equipped with damper, damper includes with rear seat 9 articulated first stiffener 10, with rear axle upper boom 6 articulated second stiffener 11 and locate between first stiffener 10 and the second stiffener 11 and its second stiffener 11 and the first stiffener 11 and locate And a first damping spring 12 is hinged to the first reinforcing rod 10 and the second reinforcing rod 11 at two ends respectively, and a second damping spring 17 is hinged between the inclined cross beam 4 and the inclined vertical beam 5.
