Description

Roller Gym

technical field

The present invention relates to a small fitness machine, especially a roller fitness machine with improved fitness effect and quick disassembly and assembly.

Background technique

As shown in FIG. 11 , the structure of a known roller exercise machine 40 includes a rod body 41 and two rollers 42. The rollers 42 are assembled at both ends of the rod body 41 and are sleeved with screw caps 43. A pivot connection is formed at the outer end of the rollers 42, and the rod body 41 is further processed to form two rough surfaces 44 on the inner sides of the two rollers 42. The rough surfaces 44 can be held by the user's hands, allowing the user to push and pull the rod body 41 with both hands. The rolling of the roller 42 achieves the purpose of exercise and fitness, but it is not difficult to find that it still has some deficiencies when looking at the above-mentioned known structure in detail, and the main reasons are as follows: (1), the roller fitness device 40 only has the function of the front and rear rollers, the When exercising, the arm can only hold the rough surface 44 with a fixed width, which cannot effectively improve the variability of the exercise and the fitness intensity, making the fitness exercise too monotonous, and the fitness effect is also insufficient; (2), The roller 42 is limited to the two ends of the rod body 41 by the locking of the screw cover 43. Since the roller 42 needs to rotate relative to the rod body 41, the clearance between the roller 42 and the rod body 41 needs to be precisely controlled. 43 is not recommended to be disassembled when it is not necessary, and the disassembly and assembly of the screw cover 43 is also quite troublesome, so the conventional roller exercise machine 40 does not have the function of convenient disassembly, carrying and storage.
