Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 3, the massage chair grounding switch mechanism of the present embodiment includes a sliding rod 10, a sliding shaft sleeve 15 and a rotating plate 12, wherein the sliding shaft sleeve 15 is connected to one end of the sliding rod 10, one end of the sliding rod 10 is provided with a stepped structure, the sliding shaft sleeve 15 is installed on a stepped thin portion of the sliding rod, a portion of the sliding shaft sleeve 15 extending out of the sliding rod 10 is connected to the rotating plate 12, and the rotating plate 12 can rotate around the sliding shaft sleeve 15; the micro-switch 11 is arranged at the position, close to the sliding shaft sleeve 15, of the sliding rod 10, and the micro-switch 11 is arranged at the step-type thick part and right above the sliding shaft sleeve 15 through screws; the elastic member in this embodiment is a torsion spring 14. When the rotating plate 12 touches the ground in use, the rotating plate 12 moves upward to contact the micro switch 11.

On the basis of the above, as shown in fig. 3, the rotating plate 12 includes a fixed plate, a step shaft 123, an optical axis 122 and a sleeve 121, and the step shaft 123, the optical axis 122 and the sleeve 121 are all vertically and fixedly connected to the fixed plate. The fixed connection is welding, the joint of the sleeve 121 and the rotating plate 12 is communicated, the sliding shaft sleeve 15 penetrates through the rotating plate 12 and is arranged in the sleeve 121, the torsion spring 14 is sleeved outside the sleeve 121, and the torsion spring 14 is fixed outside the sleeve 121 through the elastic sheet and the screw; the long arm of the torsion spring 14 is connected with the step shaft 123, and the short arm is placed on the vertical plane where the step-type thin part and the thick part of the sliding plate are connected; the distance from the optical axis 122 to the microswitch 11 is less than the distance from the step axis 123 to the microswitch 11; the optical axis 122 controls the connection or disconnection between the action spring plate of the micro switch 11 and the contact. When the rotating plate 12 touches the ground, the rotating plate moves upwards, so that the optical axis 122 is contacted with the action elastic sheet of the microswitch 11, the action elastic sheet is pressed upwards and is communicated with the contact, and the lifting assembly 40 stops lifting; when the rotating plate 12 leaves the ground, the micro switch 11 is reset by the torsion spring 14, and the lifting assembly 40 operates.
