Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, in particular to a multifunctional sports training device. Background Art

[0002] In the prior art, sports training equipment is widely used in homes, gyms and other scenarios to meet users' needs for training upper limbs, lower limbs and core muscle groups. Common equipment includes pull-ups, steppers and resistance bands. Pull-ups usually use a fixed crossbar structure to exercise the upper limbs and back muscles through hanging movements; steppers simulate the movement of going up and down stairs through pedals to train the strength of the lower limbs; resistance bands provide resistance training for the upper or lower limbs through elastic tension. These equipment are simple in design and easy to operate. They can train specific muscle groups and meet some fitness needs. Some multi-functional equipment attempts to integrate multiple training functions, such as achieving different training modes through adjustable crossbars or additional tension ropes to improve equipment utilization and user experience.

[0003] However, the multifunctional exercise equipment in the prior art has obvious defects. First, most of the equipment has a single function. For example, the pull-up machine is limited to upper limb training, and the stepper is limited to lower limb training, which is difficult to meet the needs of comprehensive fitness. Secondly, the adjustability and portability of existing equipment are insufficient. For example, the height of the crossbar is fixed and cannot adapt to users of different heights; the pedals are mostly fixed, which takes up space and is inconvenient to disassemble. In addition, the resistance of the tension rope is inconvenient to adjust, which limits the flexibility of training intensity. Although some multifunctional equipment integrates multiple functions, they have complex structures, high manufacturing costs, and are difficult to install and maintain, making them difficult to be widely used in home scenarios. Therefore, there is an urgent need for a multifunctional exercise equipment with a simple structure, diverse functions, and easy adjustment and disassembly to overcome the above-mentioned defects.
