Dual-mode stepper

Abstract

The invention belongs to the technical field of indoor fitness equipment, and relates to a dual-mode stepper. A front big pipe in running fit is arranged on a base, a front center shaft is arranged in the front big pipe and is fixedly connected with the base, treading pipe transverse shafts, driving shafts and a lower fixed piece are fixed to the front big pipe, and treading pipe front transverse pipes are in running fit with the treading pipe transverse shafts; a connecting rod and a driving piece are arranged at the inner side of each treading pipe, wherein a driving rod and a driving sleeve are arranged on the driving piece, and the driving sleeve is matched with the driving shaft in a rotating mode; a big fixed base is arranged on a middle supporting pipe and provided with a handle, a mode switching pin capable of moving vertically and a rotatable swing shaft center sleeve are arranged in the big fixed base, an upper positioning piece is arranged on the swing shaft center sleeve, swing shafts are arranged at the two sides of the upper positioning piece, square sleeves are arranged at the outer sides of the swing shafts, and the driving rods are matched with the square sleeves in a stopped and connected mode; the mode swing pin is in clearance slide fit with the lower fixed piece and the upper positioning piece. The dual-mode stepper is simple in structure, good in fitness effect and convenient to operate.

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
