Description

Power-assisted arm-pressing dorsal muscle training machine and using method thereof

Technical Field

The invention relates to the technical field of fitness equipment, in particular to a power-assisted arm-down back muscle pressing training machine and a using method thereof.

Background

The action of pressing down the arms is a good method for exercising the back muscles, mainly stimulates the upper middle part of the latissimus dorsi, and simultaneously exercises the retropular deltoid, the long head of the triceps brachii, the infraspinatus, the small circular muscle, the large circular muscle and the like, and is always well favored by people.

When the body-building is taken exercise, the straight arm is often replaced by the arm pressing back muscle training machine, the arm pressing back muscle training machine usually adopts sitting posture training, the two hands are upwards lifted to hold the pressing rod, the chest is pushed up to tighten the core part of the abdomen, the upper arm is driven to press downwards by the force of the latissimus dorsi, when the two hands press downwards, the contraction force of the back muscle is concentrated to press downwards, the lower arm is pressed to the position of the lower abdomen and stops slightly, and then the control force of the back muscle is slowly restored.

When the arm pressing back muscle training machine is used for training, because the upper arm is difficult to exert force at the initial stage of pressing after being lifted, the lifting amplitude of the existing arm pressing back muscle training machine is generally not high enough, so that the stroke of the arm pressing action is short, and the back muscle is difficult to be fully exercised and stretched.

Disclosure of Invention

The invention provides a power-assisted arm-down back muscle pressing training machine and a using method thereof, aiming at the defects of the prior art.

The invention is realized by the following technical scheme, and provides a power-assisted arm back-pressing muscle training machine which comprises a rack, a back-pressing frame hinged on the rack and a load frame hinged on the rack, wherein the rack is provided with a backrest, the back-pressing frame comprises two swing arms hinged with the rack and an operation part arranged on the swing arms, the two swing arms are respectively positioned at the left side and the right side of the backrest, the swing arms are fixedly connected with a torque disc, the circumferential surface of the torque disc is connected with the load frame through a transmission rope, the load frame is provided with a load, and the power-assisted arm back-pressing muscle training machine also comprises a power-assisted device capable of pushing the load frame.

When the device is used, the back of an exerciser is supported by the backrest, the exerciser operates the power assisting device to push the load frame to move upwards, the exerciser can support the operating part on the arm conveniently, the exerciser drives the operating part by the arm, and drives the upper arm to press downwards by the force of the latissimus dorsi, so that the lower pressing frame is driven to rotate, the transmission rope is pulled by the torque disc, and the load frame is pulled to move upwards by the transmission rope; the arm is pressed down to the position of the lower abdomen, stops slightly, and then is slowly restored by the control force of the back muscle; when the lower pressing frame is restored, the lower pressing frame is restored backwards as much as possible, so that the back muscles are fully stretched; the pressing and resetting actions are repeated, and when the pressing stroke begins each time, the upward assisting force can be applied to the load frame through the assisting device.
