Massage chair frame

Abstract

The invention relates to a massage chair frame, in particular to a massage chair frame used for controlling the adjustment of a calf rack. The massage chair rack comprises a backrest rack, a calf rack, a fixing rack, a backrest rack rotation control mechanism, a calf rack stretch control mechanism and a calf rack rotation control mechanism, wherein the calf rack stretch control mechanism comprises an electric calf rack stretch push rod, a box-shaped rotating rack, a left connecting rod, a right connecting rod, a left calf rack support rod and a right calf rack support rod, and the calf rack rotation control mechanism comprises an electric calf rack adjustment push rod and a calf ejector rod. The purpose is to design a massage chair frame which can adjust the angle of the calf rack and also can control the storage of the calf rack. When compared with the prior art, the massage chair frame not only saves the occupied space of the massage chair and improves the appearance conciseness andutilization applicability of the massage chair, but also has the advantages of large calf rack adjustment angle, convenience and good stability and the like.

Description

technical field [0001] The invention relates to a massage chair frame, in particular to a massage chair frame for adjusting and controlling the calf frame. Background technique [0002] Among the existing massage chair seat frame and calf frame structure, their common point is exactly: most massage chair calf frames can only adjust the angle (because the upper ends of the calf frame are all hinged on the seat frame), they cannot Store them in the seat frame; the calves of a small number of massage chairs can be stored in the seat frame, but when the calf frame protrudes out of the seat frame, the angle of the calf cannot be adjusted. If you use these two kinds of massage chair calf mechanisms, there will be two problems. First, if you use the structure of the former massage chair calf, since the upper end of the calf frame is hinged on the seat frame, the entire calf can only be hinged The pin shaft of the massage chair rotates. The calf frame of the massage chair with this...

[0002] Among the existing massage chair seat frame and calf frame structure, their common point is exactly: most massage chair calf frames can only adjust the angle (because the upper ends of the calf frame are all hinged on the seat frame), they cannot Store it inside the seat frame; there are a small number of massage chairs whose calves can be stored inside the seat frame, but when the calf frame protrudes out of the seat frame, the angle of the calf cannot be adjusted

If you use these two kinds of massage chair calf mechanisms, there will be two problems. First, if you use the structure of the former massage chair calf, since the upper end of the calf frame is hinged on the seat frame, the entire calf can only be hinged The pin shaft of the massage chair rotates. The calf frame of the massage chair with this structure can only adjust the angle and cannot be stored in the seat frame. This kind of massage chair can satisfy people's comfort when massaging the calf, but the calf will be damaged when it is not in use. It takes up a certain amount of space, and when people want to sit up and rest, they must take off their shoes first, otherwise the calf frame of the massage chair will be dirty, which will be very inconvenient and not beautiful; secondly, if the latter structure is used The calf frame of the massage chair, the calf frame can be stored in the seat frame when not in use, which can save a certain amount of space and is more beautiful. Usually, the massage chair is used as a sofa, and it will not block people's feet. You don't need to take off your shoes. You can sit directly on the massage chair and rest, but when the calf frame stretches out of the seat frame, because the angle of the entire calf cannot be adjusted, it will affect the comfort of people when massaging the calf, because everyone needs to massage the calf the angle is different
