Multifunctional comprehensive trainer

Abstract

The invention belongs to the technical field of fitness equipment, and particularly relates to a multifunctional comprehensive trainer. The trainer comprises a main frame body, a bicycle assembly, a sailing boat assembly and a rowing assembly; the bicycle assembly is arranged on one side of the main frame body, the rowing assembly is arranged on the other side, and the sailing boat assembly is located on the uppermost portion of the main frame body. The trainer integrates a bicycle, a rowing machine, a sailing machine and a skiing machine reasonably, provides multiple body building modes for body builders, is a multi-purpose machine, and highly caters to the market demand; and the trainer is reasonable in combination, the problem that the length and the size are increased due to combination of multiple training modes is avoided to the greatest extent, and although the size and the length are increased compared with those of a single product, the trainer is compressed to the greatest extent, and the space design is reasonable.

Problems solved by technology

[0002] Due to the presence of foreign matter in the sludge, if the foreign matter is too large, the foreign matter will be stuck between the two bicycle transmission belts, which is prone to failure. In the existing structure, a compression spring is generally set on one side of the driven knife shaft. When between the bicycle transmission belts, the driven knife shaft presses the compression spring and moves to the outside, the gap between the bicycle transmission belts becomes larger, the foreign matter falls smoothly, and the driven knife shaft returns under the action of the compression spring to reduce the failure rate, but this This structure has certain shortcomings. The dynamic force of ordinary compression springs changes greatly. Even when small foreign objects pass through, ordinary springs will frequently deform, and the driven knife shaft will move frequently, which will inevitably affect the quality of cutting strips, especially for a long time. After use, ordinary springs age and their performance declines significantly. Ordinary springs are generally built in grooves, and installation and replacement are cumbersome, which is not conducive to maintenance. In addition, in the existing structure, due to the displacement of the driven shaft tool and the rotation of the driving shaft tool is not synchronized. , After returning to the position, there will be a tooth punching phenomenon with the drive shaft tool, which will seriously affect the service life
