Description

Technical Field

[0001] The utility model relates to the technical field of massagers, and particularly relates to a telescopic and retractable calf wall-mounted mechanism. Background Art

[0002] In the prior art, massage chairs usually adopt a reclining mode for massage, and it is necessary to rotate and lift the calf support. At this time, if a hip-twisting mechanism is added to the calf support, the height of the calf position will inevitably increase, and at this time, the calf part will be in a suspended state, and most of the force will act on the buttocks and waist positions, resulting in a poor experience during massage. Summary of the Invention

[0003] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a telescopic and retractable calf wall-mounted mechanism, which adopts a lifting frame to reduce the height of the calf support, so as to avoid better effects when the calf is suspended at a high height.

[0004] The utility model discloses a telescopic and retractable calf wall-mounted mechanism, which includes a seat, a backrest frame that can rotate and recline relative to the seat, a backrest frame driving member for driving the backrest frame to recline, a calf support that can rotate relative to the backrest frame, and a calf support driving member for driving the calf support to rotate and lift. The characteristics are as follows: It also includes a lifting frame and a driving assembly for driving the lifting frame to lift and retract, and the calf support is rotatably arranged on the lifting frame and lifts synchronously with it.

[0005] Adopting the above technical solution, during use, the backrest frame driving member can drive the backrest frame to recline. Further, the calf support driving member can drive the calf support to rotate and lift. At this time, the user's calf will almost be in a highly suspended state. At this time, the driving assembly drives the lifting frame to descend, thereby reducing the position of the calf, reducing the force on the waist and buttocks, making the massage chair applying this structure suitable for more customer groups, and by adjusting the lifting of the lifting frame, the position of the legs can also be controlled.

[0006] A further setting of the utility model: The driving assembly includes a base, a support connecting rod, and a lifting driving member for driving the support connecting rod to swing. One end of the support connecting rod is hinged to the base, and the other end is hinged to the lifting frame. And at least two groups of support connecting rods are provided, and the two groups of support connecting rods are respectively located on opposite sides of the lifting frame. Each group of support connecting rods has at least two, and the support connecting rod forms a parallelogram support structure with the base and the lifting frame. The base is arranged on the backrest frame, and the lifting driving member is arranged on the base and acts on the lifting frame.

[0007] With the above technical solution, the cooperation of the lifting drive member and the support link can drive the lifting frame to swing along an arc, which can not only drive the lifting frame to lift, but also drive the lifting frame to move back and forth, achieving multiple effects with one move. There is no need to set multiple drive members, which not only liberates the installation space but also reduces the manufacturing cost.

[0008] A further setting of the present utility model: An extension frame extending forward and upward is further provided on the lifting frame. The calf frame is arranged on the lifting frame through the extension frame, and the calf frame drive member is also arranged on the extension frame.

[0009] With the above technical solution, a space for avoidance is required for the relative rotation of the calf frame. The extension frame facilitates the installation of the calf frame and the calf drive member, and also facilitates the movement of the calf frame.

[0010] A further setting of the present utility model: A massage seat for foot massage is further provided on the calf frame. The massage seat is guided and slid on the calf frame, and a telescopic drive member for driving its guided sliding is also provided on the calf frame. A clamping member for clamping the foot is further provided on the massage seat.

[0011] With the above technical solution, the massage seat can massage the foot. Further, the telescopic drive member drives the massage seat to stretch and the clamping member clamps, which can further stretch the leg muscles.

[0012] A further setting of the present utility model: A hinge frame is arranged on the lifting frame corresponding to the position of the lifting drive member. An arc-shaped plate extending backward is arranged on the hinge frame, and the output end of the lifting drive member is hinged on the arc-shaped plate.

[0013] With the above technical solution, the use of the hinge frame and the arc-shaped plate facilitates the installation of the output end of the lifting drive member and the angle adaptation during operation. Description of the Drawings
