Rotary waist wresting treadmill

Abstract

A rotary waist wresting treadmill belongs to the technical field of indoor fitness equipment, and comprises a base plate framework assembly; an inverted cylindrical front upright post is arranged on the base plate framework assembly in a matched manner; a hollow elastic body, which is in clearance fit with the cavity of the front upright post, is arranged in the cavity of the front upright post; a hollow central large shaft is arranged in the central through hole in the elastic body in a matched manner; a central small shaft and a compression spring are arranged in the cavity of the central large shaft; a square pipe sleeves the middle of the elastic body; a square pipe fixing screw is locked for connection after penetrating a square pipe fixing hole, an elastic body fixing through hole, a central large shaft fixing hole and a longitudinal strip-shaped central small shaft positioning hole; a central small shaft square wedge is arranged at the upper end of the center small shaft; a transverse shaft positioning sleeve sleeves the central small shaft square wedge tightly; a hollow transverse shaft is fixedly arranged on one side of the transverse shaft positioning sleeve; a fixing seat is arranged in the middle of the transverse shaft in a matched manner; a pedal bracket rotationally matched with the transverse shaft in a sleeving manner is arranged on the transverse shaft outside the fixing seat; pedals are arranged on the two sides of the pedal bracket respectively. The rotary waist wresting treadmill has the advantages that the structure is simple; the cost is low; the production technology is easy to control; the degree of waist wresting is moderate; the body-building effect is good; the operation and use are convenient.

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...
