Fitness trainer

Abstract

The invention discloses a fitness trainer. The fitness trainer comprises a machine frame, a crankshaft, rocking handles and a damping device; the crankshaft is rotatably mounted at the machine frame and comprises a main shaft neck, a connecting rod neck, and a crank which is used for connecting the main shaft neck and the connecting rod neck; the rocking handles are fixed to the two end parts in the axial direction of the crankshaft; the damping device is fixed at the machine frame, is used for providing rotating resistance for the crankshaft, and is a piston type hydraulic cylinder; the axial direction of the piston type hydraulic cylinder is perpendicular to the axial direction of the crankshaft; a cylinder body is in hinged cooperation with the machine frame; the end part of a piston rod which is positioned out of the cylinder body is in hinged cooperation with the connecting rod neck. The overall trainer can achieve the purpose of keeping fit by only five parts, so that the structure is simple, and a training operation is convenient; the exercising force can be controlled by increasing the rotating resistance of the crankshaft; the damping device adopts a hydraulic cylinder mode, and the friction among parts is reduced, so that noises and the service life loss of the fitness trainer when the fitness trainer is operated are greatly reduced; bi-directional rotation, namely, clockwise movement and anticlockwise movement, can be realized by the rocking handles, and directional limitation is avoided.

Description

technical field [0001] The invention relates to a fitness training device, especially a fitness training device. Background technique [0002] In modern society, with the extension of working hours, the acceleration of the pace of life, and the increase of work pressure, people's physical condition is getting worse and worse, and there are more and more sub-healthy people.

[0003] With the improvement of scientific awareness, fitness pays more attention to scientific training, which is mainly reflected in the science of training methods and the science of training equipment. At present, there are not many training equipment for upper limbs on the market, and most of them are purely mobile equipment, which cannot adjust the...

AI Technical Summary

Problems solved by technology

At present, there are not many training equipment for upper limbs on the market, and most of them are purely mobile equipment, which cannot adjust the training strength according to the needs of trainers. The most common ones are the turntables used for hand training for the elderly in parks or communities.

However, some other upper limb training equipment with strength conditions have the following defects: 1. Due to the complex structure of the equipment and many accessories, the whole is bulky; 2. The noise is large due to the friction between the accessories during use; Accidents occur, causing users to be injured; 4. High requirements for the site and high equipment costs
