A dual-mode stepper

Abstract

A dual-mode stepper belongs to the technical field of indoor fitness equipment. The base is provided with a front large pipe for rotation fit, and a front central shaft is arranged in the front large pipe, and the front central shaft is fixedly connected with the base. The horizontal axis of the tube is rotated and matched; the inner side of the pedal tube is provided with a connecting rod and a driving piece, and the driving piece is provided with a driving rod and a driving sleeve, and the driving sleeve is rotatably matched with the driving shaft; A mode switching pin that can move up and down and a rotatable center sleeve of the swing shaft are arranged in the fixed seat, an upper positioning piece is arranged on the center sleeve of the swing shaft, a swing shaft is arranged on both sides of the upper positioning piece, a square sleeve is arranged outside the swing shaft, and the drive rod and the square sleeve are arranged. Sleeve blocking fit; mode switching pin and the lower fixed piece, upper positioning piece clearance sliding fit. The dual-mode step machine has the advantages of simple structure, good body-building effect and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of indoor fitness equipment, in particular to a dual-mode stepper. Background technique [0002] At present, most common steppers on the market have four motion modes: up and down, left and right, rotation, outward swing and internal swing. The single motion mode has poor fitness effect and low comprehensive utilization rate. Multi-mode steppers have always attracted people's attention. For example, the patent number is 201320617543.9, named: stepper with action mode switching function, 201020622308.7, named: double-action stepper structure, 201320618757.8, named: dual-function stepper, 201420807637.7, titled: A kind of patented technology such as a shifting two-function stepper is very popular with users, but because of its strict structure and production process requirements, its products have many movable joints, and it is difficult to control the machining accuracy and movable gap, which leads to this S...

[0002] At present, the common steppers on the market are mostly single four motion modes: up and down, left and right, rotation, outward swing and internal swing. Multi-mode steppers have always attracted people's attention, such as patent number 201320617543.9, named: stepper with action mode switching function, 201020622308.7, named: double-action stepper structure, 201320618757.8, named: dual-function stepper, 201420807637.7, titled: A kind of patented technology such as a shifting two-function stepper is very popular with users, but because of its strict structure and production process requirements, its products have many movable joints, and it is difficult to control the machining accuracy and movable clearance, which leads to this Such products have poor stability and high noise during use, seriously affecting the use and sales of such products
