[0027] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present application, and should not be construed as limiting the present application.

[0028] In the description of the embodiments of the present application, it should be understood that if there are directional indications in the embodiments of the present application, such as up, down, left, right, front, back, inside, outside, etc., the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] In the embodiments of the present application, unless otherwise clearly specified and limited, if there are terms such as "installed", "connected", "connected", "fixed", etc., they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0031] See also Figure 1 to Figure 6 As shown, the present application provides a technical solution: a sliding and flipping massage mechanism for a chair, characterized in that it comprises: a seat 1 and a backrest 2, wherein the seat 1 is provided with a cavity 10 at the waist of a human body, and the backrest 2 is arranged in the cavity 10; one side of the backrest 2 is provided with a massage surface 3 for massaging the waist of a human body, and the other side of the backrest 2 is provided with a leaning surface 4 for leaning on for long-day use, a handle rope is provided on the top or bottom of the backrest 2, and positioning pins 100 at both ends of the backrest 2 are pinned in the cavity 10, and the backrest 2 rotates on the seat 1 around the pin joint of the positioning pin 100.

[0032] When in use, by flipping the backrest 2, the massage surface 3 or the leaning surface 4 can be directed toward the user's waist, thereby meeting the user's needs for massage or long-term sitting.

[0033] It can be understood that the backrest 2 can be directly pulled to rotate by the handle rope on the backrest 2, so as to quickly realize the flipping action, which is convenient for the user to operate.

[0034] In some embodiments, the outer contour of the seat 1 is adapted to the curve of the human body, the outer wall of the seat 1 is provided with a fully wrapped first soft package 11, the backrest 2 includes a base plate 20, and the outer wall of the base plate 20 is provided with a fully wrapped second soft package 21. By wrapping the seat 1 and the backrest 2 with the first soft package 11 and the second soft package 21 respectively, the comfort of the seat can be further improved.

[0035] In some embodiments, both ends of the base plate 20 are provided with a slide rail 200 for inserting the positioning pin 100. When the base plate 20 rotates, it will be restricted by the pin connection of the positioning pin 100, thereby avoiding separation from the seat 1, making the seat 1 equipped with the sliding and flipping massage mechanism of the chair more integrated.

[0036] Furthermore, a slide groove cavity 201 is provided in the slide groove rail 200 for the positioning pin 100 to slide. When the base plate 20 rotates, the base plate 20 can move along the positioning pin 100 through the slide groove rail 200, so that the base plate 20 can be pulled outward and pushed back again when it rotates, thereby reducing the space required for the base plate 20 to be close to the side of the seat 1 when it rotates.

[0037] In some embodiments, the positioning pin 100 is inserted into the slide rail 200 and is provided with a positioning foot 101 to prevent derailment, and the linear rail 20 is provided with a positioning cavity 202 for the positioning foot 101 to be inserted. The positioning foot 101 on the positioning pin 100 is always inserted in the positioning cavity 202 on the linear rail 20, thereby preventing the backrest 2 from detaching from between the positioning pins 100, so as to ensure that the backrest 2 can always be flipped.

[0038] In some embodiments, the massage surface 3 includes a massage terminal 30 that simulates hand pressure, and the massage terminal 30 is fixed on the substrate 20 .

[0039] In some embodiments, at least one of the positioning pins 100 is hollow so that a power line of the massage terminal 30 can pass through.

[0040] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
