Description

Technical Field

[0001] The invention relates to a three-section guide rail massage chair. Background Art

[0002] The existing L-shaped rail massage chairs, especially the larger ones, are limited in height due to the L-shaped back frame. A slightly larger massage chair can only be loaded in two layers at most, which results in a waste of loading volume and high freight costs.

[0003] The existing massage chair rails mainly include straight rails and L-shaped rails. The straight rails connect the seat and the back in sections, and the movement of the massage chair can only run up and down on the back, or massage on the seat alone; the L-shaped rails realize the movement from the head to the buttocks, and the angle between the back and the seat of the entire backrest is fixed in an L-shaped shape. The user can only experience massage at a fixed angle, and the angle between the back and the seat cannot be adjusted. The stretching massage of the human body may not be well stretched, and the comfort is not enough; the existing technical solution cannot realize the full massage from the back to the seat in the structure that realizes the adjustment of the seat and back angles. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a three-section guide rail massage chair, which can achieve the effect of reclining and reducing the packaging height of the massage chair by rotatable and foldable back frame and seat frame.

[0005] The present invention is achieved through the following technical solutions:

[0006] A three-section rail massage chair, comprising a base, a chair frame and a movement, wherein the chair frame comprises a seat frame and a back frame, wherein the seat frame is connected to the base, wherein the seat frame is provided with a seat rail, wherein the back frame is provided with a back rail, wherein the back frame is also hingedly matched with the seat frame, wherein a first push rod is provided between the back frame and the seat frame, wherein the first push rod pushes the back frame to rotate relative to the seat frame;

[0007] It also includes a lifting mechanism and a lifting guide rail arranged on the lifting mechanism, wherein the lifting mechanism and the lifting guide rail are arranged between the seat frame and the back frame;

[0008] The lifting mechanism drives the lifting and sinking of the lifting guide rail. When the lifting guide rail is lifted and the back frame rotates to a position away from the seat frame, the lifting guide rail is connected with the seat guide rail and the back guide rail so that the movement can reciprocate between the seat frame, the lifting guide rail and the back frame.

[0009] When the lifting mechanism drives the lifting guide rail to sink, the back frame can rotate toward the seat frame so that the back guide rail is close to the seat guide rail.

[0010] In an embodiment of the present invention, the seat frame is reciprocatingly slidably arranged on the base, and the lifting mechanism is arranged on the seat frame.

[0011] The base is provided with an arc-shaped guide rail, and the side end of the chair frame is provided with a roller matched with the arc-shaped guide rail. A second push rod is also provided between the base and the chair frame. The second push rod is extended and retracted, and the roller reciprocates in the arc-shaped guide rail to realize the reciprocating sliding of the chair frame relative to the base.

[0012] The three-section rail massage chair of the present invention has the following beneficial effects:

[0013] 1. Through the seat frame and the back frame, and the lifting mechanism and lifting guide rails arranged therebetween, and in conjunction with the power of the first push rod, the back frame can be turned back relative to the seat frame. Specifically, when the lifting mechanism sinks, the back frame rotates close to the seat frame to achieve the back frame turning back. When the lifting mechanism rises, the seat guide rail, the back guide rail, and the lifting guide rail are interconnected, the movement can reciprocate between the seat frame, the lifting guide rail, and the back frame to achieve full body massage.
