Massager tightness degree adjusting connecting device

Abstract

A massager tightness degree adjusting connecting device comprises a mounting seat and a knob, a plurality of shifting columns are arranged on the knob, the shifting columns are sleeved with adjusting gears, a mounting opening is formed in the mounting seat, a plurality of toothed protruding bodies are evenly distributed in the mounting opening in the circumferential direction, and gear teeth on the adjusting gears are meshed with the toothed protruding bodies. A protruding head is arranged at one end of a transmission wheel, a transmission gear is arranged at the other end of the transmission wheel, and planes with the number at least consistent with that of the adjusting gears are formed on the side faces of the protruding head. The shifting columns are arranged on the periphery of the protruding head, the protruding head is connected among the adjusting gears in an inserting mode, and the adjusting gears correspond to the planes on the side faces of the protruding head respectively. After the knob is rotated, the knob drives the adjusting gears to roll on the toothed protruding bodies on the mounting seat, the adjusting gears are made to rotate on the shifting columns, and then the transmission wheel is driven to rotate through the action of the adjusting gears and the planes on the protruding head. The connecting device can adjust the tightness degree of a massager conveniently, and the size obtained after adjustment is convenient to stabilize.

Description

technical field [0001] The invention relates to a connecting device, in particular to a connecting device which can be applied to massagers for the head, neck, eyes, etc., and is used for adjusting the tightness. Background technique [0002] Corresponding parts of the human body sometimes produce soreness, so it is necessary to provide physical relief through massage. Various massagers have also emerged, such as eye massagers, neck massagers and head massagers. And people with different postures have different requirements for the size of the massager, and different people have different requirements for the massage force of the massager. Therefore, some massagers are also provided with an elastic connection device, and the elastic connection device adapts to different needs of users by adjusting the size of the massager itself and the corresponding parts of the human body. Various adjusting devices have also appeared on existing massagers, but some of these adjusting dev...

AI Technical Summary

Problems solved by technology

Various adjustment devices have also appeared on existing massagers, but some of these adjustment devices have relatively complicated structures, which are inconvenient to process and assemble

Some adjusting devices cannot maintain the adjusted size well after the adjustment is completed, that is, after the adjustment is completed, as the massager works, the corresponding size used to match the corresponding parts of the human body will gradually change. Large, this will affect the use of the massager
