Rise and fall leg pressing machine

Abstract

The invention discloses a rice and fall leg pressing machine. The rise and fall leg pressing machine is composed of a combined leg pressing rod, push rods, a control device and a movement device. Thecombined leg pressing rod is provided with cross bars with multiple heights and matched with the movement device of the rise and fall leg pressing machine, so that more height ranges can be covered. The control device comprises a voice receiver, a wire, a control circuit and a motor, wherein the voice receiver is used for receiving voices of a user such as 'rise' and 'fall' and then transmitting signals to the control circuit, and the motor is controlled to rotate by the control circuit for a circle in the forward direction or in the backward direction. The movement device comprises a gear, arack and the push rods, wherein the gear is meshed with the rack under the action of the motor and drives the rack to rise / fall by a teeth space (1-2 cm), the push rods are placed under the rack andbelow the combined leg pressing rod and used for transmitting movement in the vertical direction generated by the movement device to the combined leg pressing rod, and then the combined leg compressing rod is driven to rise or fall.

Description

technical field [0001] The invention relates to an elevating leg press machine, in particular to a fitness equipment used in parks for people to perform leg press exercises. Background technique [0002] At present, there are many ways for people to exercise, and leg pressing is one of them. The common leg press method is that people stand on one leg next to the leg press bar, and the other leg rests on the leg press bar. Although there are generally multiple leg presses in the park and they are of different heights, it is difficult to find a suitable leg press due to the large differences in height and flexibility of people. In addition, after the legs are placed on the leg pressing bar, the height of the leg pressing bar cannot be adjusted, so it is impossible to increase the difficulty of leg pressing. In the leg presser described in Patent No. 201210426001.3, the height of the strut can be adjusted with a nut and a lead screw, but the adjustment of the nut is very inco...

Problems solved by technology

Although there are generally multiple leg presses in the park and they are of different heights, it is difficult to find a suitable leg press due to the large differences in height and flexibility of people.

In addition, after the legs rest on the leg press bar, the height of the leg press bar cannot be adjusted, so it is impossible to increase the difficulty of leg press

The leg press described in Patent No. 201210426001.3 can adjust the height of the strut with nuts and leadscrews, but the adjustment of the nuts is very inconvenient

The leg press described in Patent No. 201520231895.8 uses shaking the handwheel to adjust the height of the leg pressing plate, but this invention requires someone to help shake the handwheel, and a single person can only adjust in advance, and cannot adjust the height during the leg pressing process
