Rowing body building machine capable of adjusting impedance

Abstract

The invention discloses a rowing body building machine capable of adjusting impedance. The rowing body building machine includes a base, a seat cushion set, a pedal set and two joystick sets, wherein a slide rail is arranged on the base; the seat cushion set is arranged on the slide rail in a sliding way; the pedal set is arranged at one end of the slide rail, which is different from the end where the seat cushion set is arranged; the pedal set is provided with a pedal on the two sides of the slide rail respectively; then, the joystick sets are arranged on the two sides of the seat cushion set of the slide rail respectively; each joystick set is provided with an arm rack and a swing arm; the swing arm is pivotally arranged on the arm rack through a hinge unit; the hinge unit is provided with a transmission shaft; an impedance adjusting unit is arranged in the hinge unit; in the impedance adjusting unit, a fixed plate is locked on a conical cover; a screw hole for penetrating the transmission shaft is formed in the center of the fixed plate; and a disc body with a corresponding screw sleeve is screwed on the fixed plate by using the screw hole. Through the rowing body building machine, members can be saved, the smoothness of integral action can be improved, the impedance of motion is effectively adjusted, and the training effect of the machine is enhanced.

Description

technical field [0001] The invention relates to a sports and fitness equipment, in particular to a rowing exercise machine with smooth action and adjustable impedance, so as to improve the exercise training effect of the rowing exercise machine. Background technique [0002] According to medical research, a small amount of frequent exercise is as effective in preventing heart disease as intensive exercise for a long period of time. Therefore, the industry has developed a variety of fitness equipment for users to perform fitness exercises according to their needs. Such as exercise bikes, treadmills, ski machines, rowing machines, elliptical machines, steppers and more. And all kinds of fitness equipment have its different sports training effects, take the rowing fitness equipment as an example, but a slide rail is provided on a base, and a seat cushion group that can selectively slide is provided on the slide rail, and the base The other end is provided with a set of pedals ...

AI Technical Summary

Problems solved by technology

However, this kind of universal pivot structure includes multiple pivot components. Although it can be easily folded, it increases the number of assembled components and greatly increases the probability of damage during use.

At the same time, it uses the oil pressure rod to generate resistance. During use, there will be a phenomenon that the compression direction of the oil pressure rod is inconsistent with the action direction of the joystick, causing its movement to be unsmooth and may cause unnecessary sports injuries.

At the same time, because the oil pressure rod uses hydraulic oil as the impedance medium, its impedance is determined by the thickness of the hydraulic oil, but the thickness of the hydraulic oil of the oil pressure rod will be changed by the temperature rise before and after use, so it will affect to the overall training effect

Furthermore, most of the existing oil pressure rods cannot adjust their impedance, and cannot meet the different exercise needs of different users

[0004] The reason is that the present inventor has made an in-depth discussion on the problems faced by the aforementioned existing rowing fitness equipment in use, and actively seeks a solution based on years of experience in research and development and the needs of use. After continuous efforts in research and Trial production, and finally successfully developed a rowing fitness machine with adjustable impedance, so as to overcome the shortcomings of the existing rowing fitness equipment caused by the unsmooth movement and the inability to adjust the impedance
