Squatting training device

Abstract

The invention relates to a squatting training device. The device comprises a main frame, a connecting rod structure, an upper lifting frame, a pneumatic box and a gasholder, wherein the connecting structure comprises a first connecting rod and a second connecting rod, the first end of the first connecting rod is rotatably fixed to the lower portion of the main frame, and the second end of the first connecting rod is rotatably connected with the first end of the second connecting rod; the upper lifting frame comprises a first shoulder lifting rod and a second shoulder lifting rod which are parallel, the first shoulder lifting rod and the second shoulder lifting rod fixedly and mutually form an H-shaped structure through a transverse rod, and the second end of the second connecting rod can be rotatably connected with a midpoint portion of the transverse rod; the pneumatic box comprises an air cylinder, the air cylinder comprises a piston and a piston rod, the air cylinder is fixed for rotating at a certain angle in a plane of a lengthwise direction of the air cylinder, one end of the piston rod is connected with the piston, and the other end of the piston rod is rotatably connected with one point of the first connecting rod; the gasholder is used for storing compressed gas, and the gasholder is connected with the air cylinder to supply the compressed air to the air cylinder.

Description

Technical field [0001] The present invention generally relates to the field of fitness equipment, in particular to a squat trainer. Background technique [0002] With the popularization of health knowledge and the improvement of people's living standards, people are paying more and more attention to their health. As a green way to maintain health and shape your body, fitness is increasingly favored by the public. Resistance training is a common fitness training used to improve cardiopulmonary function, shaping or performing professional physical training. Conventional resistance training equipment generally changes resistance simply by changing or adding bells or selection plates. However, the resistance of these devices will change with the user's exercise. For example, when doing a centripetal exercise (muscle contraction at this time), the resistance often becomes smaller due to the inertia of the selector itself. This resistance change is harmful during training. It not o...

This change in resistance is detrimental when training, not only does it affect training effectiveness, but it can also cause impact damage to joints and connective tissue

[0003] In addition, common resistance training equipment generally only changes the resistance by replacing or adding bell plates or optional plates. Since the specifications of the bell plates or optional plates are relatively single, the adjustment range of resistance is very limited. For example, only 5 or 10 kg, or even more than 20 kg
