Seated leg flexion and extension training device

Abstract

The invention discloses a leg flexion and extension training device in a sitting posture, which includes a trunk support mechanism, a thigh support mechanism and a load mechanism; the trunk support mechanism is hinged to the first end of the thigh support mechanism through a lockable rotating shaft structure, and the second end of the thigh support mechanism is connected to the first end of the thigh support mechanism through a hinge shaft The upper end of the connecting rod is connected flexibly, and the lower end of the connecting rod is fixedly connected with the middle section of the horizontal bar with foot support mechanisms installed at both ends; the lockable rotating shaft structure is installed on the upper end of the support frame; the housing is installed on the support frame, and the piston passes through the rope and the setting The binding member on the cross bar is connected; the foot support mechanism drives the connecting bar to rotate freely around the hinge shaft. The present invention changes the load of the training by changing the volume of the housing through the movement of the piston, and can increase the load of the muscle group by gradually increasing the load, so that the load of the muscle group can be gradually increased from small to large, improving the tolerance of the muscle group without overloading the muscle groups.

Description

Technical field [0001] The present invention relates to the technical field of fitness equipment. Specifically, it is a sitting leg flexible training device. Background technique [0002] The training of muscle groups by means of instruments can not only effectively train muscle groups that are not easy to train through daily activities, but also for effectiveness of muscle groups. However, the existing instrument for sitting leg flexion and extension training is not only cumbers, but also because the weight of the weight is fixed, the number of user weight blocks will have more contradictory psychology, that is, when the number of counterweight blocks are selected, when training, It will feel that the load is lighter, but after adding a copy, it will feel that the load is heavy, which will cause the muscle group to be small induced by the load, or the load is strong, these two training effects for muscle groups It is relatively poor, even side effects, such as fatigue damage, in...

Problems solved by technology

However, the existing equipment used for sitting leg flexion and extension training is not only cumbersome, but also because the weight of the counterweight is fixed, the user's choice of the number of counterweights will appear contradictory, that is, when a certain number of counterweights are selected for training, You will feel that the load is lighter, but after adding a counterweight, you will feel that the load is heavier, which will cause the muscle group to either have a small load response or a strong load response. These two training effects on the muscle group Both are relatively poor, and even side effects may occur, such as muscle fatigue damage. In other words, both small loads and heavy loads may cause ineffective training, which cannot increase the endurance of muscle groups
