Machine core overload protection device used on massager

Abstract

The invention belongs to the technical field of a massage chair and particularly relates to a machine core overload protection device used on a massager. The device comprises a traveling driven gear wheel and a traveling meshing pinion; the traveling driven gear wheel is sleeved on an extension shaft of the traveling meshing pinion and then a belleville spring is also sleeved on the extension shaft; the traveling driven gear wheel is squeezed by the belleville spring, so that radial grooves arranged on the lower end face of the traveling driven gear wheel are matched with radial convex semicylinders arranged on the upper end face of the traveling meshing pinion; and finally, the belleville spring and the traveling driven gear wheel are subjected to axial limiting by an axial elastic check ring. Under the overload condition, the traveling meshing pinion and the traveling driven gear wheel on an overload clutch device are in coaxial departure connection, so that a machine core traveling transmission device of the massager drives the traveling driven gear wheel on the overload clutch device to idle, and thus, the protection effect on a rack and a machine core of the massager is achieved and the overload protection effect and the protection mechanism are improved.

Description

technical field [0001] The invention belongs to the technical field of health-care massage chairs, and in particular relates to an overload protection device for a movement of a massager. Background technique [0002] Massage chair is a kind of health care equipment. By using mechanical rolling force and mechanical force extrusion, it can massage the meridians of the whole body of the human body, stimulate acupuncture points, relax muscles, and promote blood circulation, so as to achieve the purpose of medical treatment and health care. [0003] Massage devices such as massage cushions currently on the market, especially massage cushions, generally use screws to fix the massage movement in the packaging to ensure that various impacts during transportation will not cause the movement to jump teeth or cause the movement to break after the rack is broken. However, if the consumer does not read the manual and unscrew the screw with a hexagonal wrench, the power is turned on dire...

Problems solved by technology

[0003] Massage devices such as massage cushions currently on the market, especially massage cushions, generally use screws to fix the massage movement in the packaging to ensure that various impacts during transportation will not cause the movement to jump teeth or cause the movement to break after the rack is broken. However, if the consumer does not read the manual and unscrew the screw with a hexagonal wrench, the power is turned on directly, which will overload the massager movement and the rack, causing the massager movement to dry out, and the rack may break teeth. As a result, the massager may not work normally after the screw is unscrewed, which will seriously affect the service life of the massager and consumer reputation
