Leg exercise device for physical training

Abstract

The invention provides a leg exercise device for physical training. The leg exercise device comprises a bottom plate; a cylinder is arranged at the upper end of the bottom plate; the two sides of thecylinder are provided with a first pedal assembly and a second pedal assembly; each of the first pedal assembly and the second pedal assembly comprises a damping element, a pedal and a supporting plate; one end, close to the cylinder, of each supporting plate is hinged to the bottom plate; the bottom plate at the other end is provided with a first adjusting mechanism for adjusting the height of each supporting plate; a second adjusting mechanism for adjusting motion resistance force is arranged between the first adjusting mechanism and the cylinder; the pedals include a front pedal and a rearpedal detachably connected with the front pedal; one end, close to the cylinder, of the front pedal is rotationally mounted on a rotating shaft in a sleeving manner; the rotating shaft is in threadedconnection with the upper end of the cylinder; the lower end of the rear pedal is hinged to one end of each damping element; and the other end of each damping element is obliquely and downwards hingedto each supporting plate through a lifting base. According to the leg exercise device, the conversion of two training modes of stepping and leg extension is realized; the carrying is convenient; andthe motion stability and the resistance adjustability are ensured.

Description

technical field [0001] The invention relates to the technical field of physical training, in particular to a leg exercising device for physical training. Background technique [0002] In sports such as football and running, it is necessary to exercise the explosive power, flexibility, and strength of the trainer's legs. The existing leg exercise devices are inconvenient to adjust the distance between the equipment and the height of the equipment, and cannot satisfy people of different heights. need. In addition, most of the existing leg training devices are of a single pedal type, which cannot be used for training such as pedaling and kicking. However, the leg training device with multiple functions is only a simple combination of multiple training devices. The equipment is not easy to carry, takes up a lot of space, and is not easy to place. [0003] CN108031062B discloses a portable lower limb exerciser, which includes a base, a first support plate, and a second support ...

AI Technical Summary

Problems solved by technology

The device is easy to carry, but the exercise method is single, and only the kicking action of the lower limbs can be performed, and the resistance of the kicking exercise is not adjustable.

[0004] CN106334285B discloses a home fitness stepper with adjustable pressure. By using a hydraulic telescopic rod and a regulating ball valve in cooperation, the oil in the inner chamber of the second oil cylinder can be adjusted to enter the oil in the inner chamber of the hydraulic telescopic rod; The mutual cooperation of the rod, the piston push rod and the solenoid valve coil can effectively change the working resistance of the pneumatic telescopic rod, which is easy to adjust; through the pedal adjustment device installed at the bottom of the pedal, the slope of the pedal can be adjusted so as to be suitable for different difficulties training; the device can only be used for stepping training, and cannot be used for switching between stepping and kicking training, and cannot be used for multiple training methods
