A rocker shaft for a chair

Abstract

The invention discloses a handle shaft for a chair, which comprises a handle shaft main body. The handle shaft main body is composed of a handle part, a drive part and a connection part connecting the handle part and the drive part. The arm strength training mechanism is arranged on the handle shaft main body. The training mechanism is composed of a force applying mechanism and a strength adjusting mechanism. The force applying mechanism is arranged on the hand-held part. The force applying mechanism is also provided with a locking mechanism for limiting the force applying mechanism. A limiting mechanism is provided at the end of the utility model, and the force applying mechanism and the force regulating mechanism are connected through a connecting plate. The present invention can use the arm strength training mechanism provided by the arm strength training mechanism to train the arm strength while using the rocker shaft to drive the massage structure to massage the back, which solves the problem of the single function of the rocker shaft in the prior art, and has high practicability; The detachable form of the main body of the rocker shaft is improved, and then the grip strength training mechanism can be used to realize the training of the grip strength, which further enhances the practicality of the rocker shaft.

Description

technical field [0001] The invention relates to a handle shaft, in particular to a handle shaft used for chairs. Background technique [0002] Patent 1: According to "A Manual Massage Chair" disclosed by China Invention (Application No.: CN201410232823.7), it belongs to the technical field of massage device structure. The main purpose of designing this manual massage chair is: in order to solve the problem that people can move their arms while resting on the seat, and reach the effect of massaging the back of the body through the movement of the arms. The manual massage chair is mainly composed of a crank handle, an armrest, a seat plate, a chair leg, a chair back, a threaded rod, and a transmission belt. Its features are: both the crank handle and the threaded rod can be rotated 360 degrees; There are grooves, and the transmission belt is installed on these two grooves; the bottom of the handrail can be driven to rotate by turning the handle on the armrest with the arm, a...
