Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in fig. 1 to 4, the rear axle for the multifunctional body-building tricycle comprises a middle axle 1 and a side axle 2, wherein two ends of the middle axle 1 are sleeved with chucks 3; the end part of the side shaft 2 is fixedly sleeved with a driving flywheel 4, and an inner hole is processed at the end part of the side shaft 2; short shafts 5 are processed at two ends of the middle shaft, and the short shafts 5 are sleeved in inner holes of the side shafts 2 through needle bearings 6; internal teeth are processed in the chuck 3, the outer ring of the driving flywheel 4 is meshed with the internal teeth, and when the middle shaft 1 rotates, the chuck 3 drives the driving flywheel 4 to rotate the side shaft 2; and a first flywheel 7, a connecting disc 8, a locking disc 9 and a second flywheel 10 are sequentially sleeved between the chucks 3.
A section of mounting groove 11 is processed on the middle shaft 1; the side edges of the chuck 3, the first flywheel 7, the connecting disc 8, the locking disc 9 and the second flywheel 10 are respectively provided with a connecting seat, the connecting seats are connected with locking screws 12, the bottoms of the locking screws 12 penetrate into the mounting grooves 11, and the chuck 3, the first flywheel 7, the connecting disc 8, the locking disc 9 and the second flywheel 10 are fixed with the middle shaft 1.
Positioning pins 13 are uniformly distributed on the side edge of the second flywheel 10; the side surface of the locking disc 9 is provided with a positioning pin hole 14 corresponding to the positioning pin 13, the positioning pin 13 can be inserted into the positioning pin hole 14, the flywheel II 10 is used for being connected with a crank structure on the tricycle, and the flywheel 10 drives the middle shaft 1 to rotate through manually operating the crank structure, so that the upper limb exercising effect of a human body is achieved.
Inserting rods 15 are evenly distributed on the periphery of the connecting disc 8, threaded mounting holes are formed in the inserting rods 15, the inserting rods 15 are used for inserting the balance weight disc, the balance weight disc is fastened with the threaded mounting holes in the side face of the inserting rods 15 through screws, after the balance weight disc is mounted, the rotating resistance of the middle shaft 1 is increased, and a body building effect can be achieved.
