The utility model relates to a leg lifting mechanism of a massage chair, which comprises an L-shaped connecting frame, a leg lifting frame, a linkage mechanism, a bottom frame, two front support rods, two rear support rods and an electric push rod; the front and rear support rods are movably articulated on the L-shaped connecting frame and the bottom frame, and are driven and maintained in a stable state by an electric push rod; the back of the leg lifting frame is articulated at the front of the L-shaped connecting frame, and the L-shaped connecting rod moves forward. When lifting the legs, the legs are lifted by a linkage mechanism, which includes a traction rod and a driving rod on both sides. One end of the traction rod is articulated at the upper and middle parts of the front supporting rod on the same side, the other end is articulated at the end of the driving rod, the middle part of the driving rod is articulated at the lower front part of the L-shaped connecting frame on the same side, one end of the two driving rods is articulated with a connecting rod, and a supporting wheel is fixed in the center of the connecting rod. Collision on the back of the leg rack. Through the synchronous drive of both sides of the traction rod and the driving rod, it is neither stable nor occupies the central space. Especially when the leg rack is raised, the central part has no obstruction and is convenient for maintenance and other operations.

一种按摩椅抬腿机构
:本技术属于按摩椅领域,特别涉及一种按摩椅抬腿机构,尤其采用一根电动推杆驱动,且能前移躺靠不占用后部空间,又能抬高美腿架。
技术介绍
:专利申请号201611216818.2,公开一种前移零重力按摩椅架,包括L形连体架、底架、两前支撑杆、两后支撑杆和一根电动推杆;前、后支撑杆两端活动铰接在L形连体架和底架上,并由电动推杆驱动和保持稳定状态;其中两前支撑杆中部固定有一横杆,电动推杆一端铰接在底架上,另一端铰接在所述横杆的中部,由电动推杆直接驱动前支撑杆摆动,并牵引整个L形连体架前后移位。该专利采用一根电动推杆,结构简单,同步性好的特点,但其驱动美腿架的联动机构设计不合理,只由中部一牵引杆牵制,稳定性不佳,且挡住前部空间。如何改良现有技术的不足,即成为本技术研究的对象。
技术实现思路
:本技术的目的是设计一种由设置在L形连体架、前支撑杆两侧的联动机构驱动的按摩椅抬腿机构。本技术技术方案是这样实现的:一种按摩椅抬腿机构,包括L形连体架、美腿架、联动机构、底框、两前支撑杆、两后支撑杆和一根电动推杆;前、后支撑杆两端活动铰接在L形连体架和底框上,构成椅架两侧对称或对应的四连杆结构,并由电动推杆驱动和保持稳定状态;所述美腿架背部上沿铰接在L形连体架前沿,L形连体架前移时通过联动机构抬升美腿架;其特征在于:两前支撑杆和两后支撑杆间,对应固定有前横杆和后横杆;所述电动推杆一端铰接在底框上,另一端铰接在所述后横杆中部,由电动推杆直接驱动后支撑杆摆动,并牵引整个L形连体架前后移位;所述联动机构包括处于两侧的牵引杆和驱动杆,牵引杆一端铰接在同侧前支撑杆中上部、另 ...
