Differential lifting adjusting device of shank massage mechanism of massage chair

Abstract

The invention discloses a differential lifting adjusting device of a shank massage mechanism of a massage chair. The device comprises a mounting bracket, the mounting bracket is provided with a motorand a screw rod, the motor drives the screw rod to rotate on the mounting bracket, the screw rod comprises an upper-section screw rod and a lower-section screw rod which are coaxially connected, the screw pitch of the upper-section screw rod is different from that of the lower-section screw rod, and the screw rod is provided with a leg lifting sliding block and a foot lifting sliding block; the mounting bracket is provided with fixed sliding grooves, and a leg sliding rail and a foot sliding rail are arranged in the fixed sliding grooves in a sliding mode; and the device further comprises a leg connecting mechanism and a foot connecting mechanism, the leg connecting mechanism is connected to the leg lifting sliding block and the leg sliding rail separately, and the foot connecting mechanism is connected to the foot lifting sliding block and the foot sliding rail separately. According to the invention, the coaxially-arranged two-section screw rods are respectively matched with the two sliding blocks so as to drive a leg massage assembly and a foot massage assembly to realize synchronous differential lifting. The device is simple in structure, small in occupied assembly space and safe and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of massage chairs, and in particular relates to a differential lift adjustment device for a calf massage mechanism of a massage chair. Background technique [0002] The massage chair includes a back massage mechanism and a calf massage mechanism. In order to adapt to different human body heights and facilitate storage, the calf massage mechanism is usually set as a lifting type, such as a massage chair structure disclosed in CN201912424U. Height automatic telescopic, or CN205054764U discloses a kind of massage chair structure, and it discloses a kind of simple and easy automatic telescopic mechanism of calf. Existing massage chair calf massage mechanism comprises leg massage assembly and foot massage assembly again, and according to different human body heights, the distance between leg and foot is also not the same, that is to say, in the calf massage mechanism lifting At the same time, it is necessary to ...

AI Technical Summary

Problems solved by technology

Existing massage chair calf massage mechanism comprises leg massage assembly and foot massage assembly again, and according to different human body heights, the distance between leg and foot is also not the same, that is to say, in the calf massage mechanism lifting At the same time, it is necessary to adjust the relative position of the leg massage assembly and the foot massage assembly accordingly. To solve this problem, for example, CN206315251U also discloses a telescopic lower limb massage structure, which uses a master-slave two-stage screw mechanism to drive the leg massage assembly respectively. and foot massage components to achieve differential expansion, or CN205411571U discloses a telescopic lower limb massag
