Abstract

The invention relates to an electromagnetic locking device, in particular to a rotary joint locking device of a massage hand, belonging to the technical field of a massage device. The rotary joint locking device comprises a rotary joint mechanism and a locking mechanism for controlling the movement of the rotary joint mechanism. According to the rotary joint locking device, an electromagnetic lock is utilized for pinning a conical pin shaft into a positioning hole on a large gear at a joint to lock the joint. By adopting the locking mode, the locking mode of the existing joint locking mechanism for realizing joint locking by means of friction is changed and the problem of locking failure in the existing locking mechanism is solved.

Description

technical field

[0001] The invention relates to an electromagnetic locking device, in particular to a rotating joint locking device of a massage hand, belonging to the technical field of massage devices. Background technique

[0002] At present, there are existing rotating joint locking devices, such as the joint locking mechanism of the mechanical arm disclosed in Patent No. 01229822.0. The end shaft is equipped with an electromagnetic clutch. The half clutch with electromagnetic coil, armature and stator is fixed to the shaft seat, and the half clutch with the moving plate is fixed to the end shaft. The stator and the moving plate are arranged alternately and stacked. Closed to the surface of the armature, the armature is provided with a spring that frictionally engages the fixed and moving plates and brakes the moving plates. When the electromagnetic clutch is de-energized, the fixed and moving pieces are frictionally combined under the action of the spring and the armat...
