Damping-adjustable power roller

Abstract

The invention rates to a damping-adjustable power roller, which comprises a holding rod, a roller, a lantern ring and an adjusting assembly, the roller is rotatably arranged on the holding rod in a sleeving mode, the two axial ends of the holding rod penetrate out of the roller, the lantern ring is detachably arranged on the holding rod in the sleeving mode, a fixing piece is arranged on the lantern ring, and the fixing piece is used for fixing the lantern ring to the holding rod, the adjusting assembly comprises a shell, a rotary knob, an output shaft and a transmission assembly, the shell isfixedly connected with the lantern ring, the rotary knob is arranged outside the shell and can rotate relative to the shell, at least part of the output shaft is arranged outside the shell, the output shaft can move in the axial direction of the output shaft relative to the shell, the transmission assembly is connected with the rotary knob and the output shaft, the rotary knob rotates and drivesthe output shaft to move through the transmission assembly so that the output shaft can abut against or be separated from the roller, friction damping force can be generated between the output shaft and the roller after the output shaft abuts against the roller, and due to the fact that the output shaft can move in the axial direction, the abutting tightness degree of the output shaft and the roller can be adjusted, and adjustment of the damping degree is achieved.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a damping adjustable abdominal wheel. Background technique [0002] The abdominal wheel is a small fitness equipment that can exercise muscles, joints, and reduce weight. It is very popular among fitness trainers because of its many advantages such as durability, convenience, and relatively simple venue. However, in the prior art, since the rollers on the abdominal exercise wheel have no damping control, it is easy to lose control during abdominal exercise training, especially for beginners or trainers with poor strength control, muscle strain is prone to occur due to excessive wheel speed Or bumps may cause facial injuries, affecting use. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the first object of the present invention is to provide a damping adjustable abdominal wheel,...
