A rotary waist twisting stepper

Abstract

A rotary waist twisting stepper belongs to the technical field of indoor fitness equipment. Including the chassis frame assembly, the chassis frame assembly is equipped with an inverted cylindrical front column, the cavity of the front column is equipped with a hollow elastic body that fits with the gap, and the hollow center shaft is matched with the elastic body center through hole of the elastic body. The hollow cavity of the central shaft is equipped with a central small shaft and a compression spring, and a square tube is set in the middle of the elastic body. The square tube fixing screw passes through the square tube fixing hole, the elastic body fixing through hole, the central big shaft fixing hole, The bar-shaped central small shaft positioning hole is connected by nut locking. The central small shaft square wedge is set on the upper end of the central small shaft. The central small shaft square wedge is tightly fitted with a horizontal shaft positioning sleeve. One side of the horizontal shaft positioning sleeve is fixed Hollow horizontal shaft, the central part of the horizontal shaft is provided with a fixed seat, and the horizontal shaft outside the fixed seat is provided with a pedal bracket which is socketed and rotated with it, and pedals are respectively arranged on both sides of the pedal bracket. The above-mentioned rotary waist-twisting stepper has simple structure, low cost, easy control of the production process, moderate range of rotary waist-twisting, good body-building effect, and convenient operation and use.

Description

technical field [0001] The invention belongs to the technical field of indoor fitness equipment, in particular to a rotary waist twisting stepper. Background technique [0002] Most of the steppers currently on the market are up and down and swing left and right, and their fitness effects are not very good. Rotary steppers are very popular among users, such as the patented technologies of 200520011788.2, 201020622308.7, and 201420075526.1. It is popular, but because of its strict structure and production process requirements, it is difficult to control the movable joint clearance of its products, resulting in poor stability and high noise during use, which seriously affects use and sales. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the object of the present invention is to design and provide a technical scheme of a rotary waist-twisting stepper, which has simple structure, low cost, easy control of the production pro...
