Waist and back massager capable of fitting waist and back curve

Abstract

The invention discloses a waist and back massager capable of fitting a waist and back curve. The massager comprises a main body bracket, handrails and a massage component; the massage component is composed of a fixed bearing frame, a plurality of groups of massage rotors, rotor frames, telescopic rods, springs, convex pins and straight needle bearings, the telescopic rods are hexagonal, the massage rotors are fixed on the rotor frames and connected to one ends of the telescopic rods, the telescopic rod is assembled in the bearing fixing frame, a protruding pin is arranged at the bottom of the telescopic rod, and a spring is assembled between the telescopic rod and the bearing fixing frame. When the massage rotors make contact with the waist and the back of the human body, each massage rotor can rotate independently, and due to extrusion of the waist and the back, the massage rotors move backwards along with the telescopic rods. The multiple groups of massage rotors are changed into a state of dynamically fitting the waist and back curve of a human body and rotate independently to simulate pushing and pressing of human hands on the waist and back, so that the effects of massaging and relaxing the waist and back are achieved. The problems that the waist and back curves of the human body are diversified due to gender, age, body shape and the like, and the massage rotor cannot be comprehensively attached to the waist and back are solved.

Description

technical field [0001] The invention relates to an outdoor back massage fitness equipment Background technique [0002] The back massager is a common outdoor fitness equipment in daily life. It can relax the meridians and activate collaterals by rolling on the lower back of the human body. There are certain defects in the design of the traditional back massager: the core part of the massager is usually a one-piece massage column with raised hemispheres on the surface. When in use, because the human body structure is three-dimensional rather than flat, the integrated massage column rolls and presses the human body The waist and back can not be well fitted to the waist and back of the human body, resulting in low massage efficiency and poor massage effect. [0003] The present invention mainly realizes the floating fit massage on the user's waist and back mainly through structural innovation. By simulating the definite integral in mathematical calculus and using the method o...
