Description

Iron frame structure of massage chair capable of lying flat Technical Field The utility model relates to the technical field of iron frames of massage chairs, in particular to an iron frame structure of a massage chair capable of lying flat. Background In the fields of modern health industry and household articles, the massage armchair is used as equipment capable of relieving physical fatigue and promoting blood circulation, and the market demand of the massage armchair is continuously rising. The iron frame structure of the massage chair is used as a core component for supporting the whole equipment, bearing the body of a user and realizing angle adjustment, and the performance of the iron frame structure directly influences the comfort and applicability of the massage experience. Based on the above, the inventor finds that the iron frame structure of most massage chairs on the market has obvious limitation in angle adjustment at present, so that when a user uses the massage chair, the body is always at a certain inclination angle, the waist, the back and other parts cannot be completely relaxed, the stress points of the back and the buttocks are concentrated, local compression feeling is easy to generate after long-time use, and the massage effect is influenced.
