Description
Technical Field
[0001] The utility model relates to the technical field of massagers, and particularly relates to a wall-mounted telescopic mechanism that can meet different leg lengths. Background Art
[0002] In the prior art, a massage chair includes a base, a seat back frame, and a calf rest. The specific fixation between the calf rest and the seat back frame cannot be adjusted relatively. Since the lengths of people's feet in society vary, it can only be set according to approximate specifications. When some people have relatively long or short feet, the massage position will deviate greatly, thus affecting the massage effect for customers. Summary of the Invention
[0003] Objective of the utility model: In order to overcome the defects of the prior art, the utility model provides a wall-mounted telescopic mechanism that can meet different leg lengths. Through a telescopic frame, the calf rest can be driven to adjust back and forth independently, so as to be suitable for groups with different leg lengths to use, and it is more comfortable when in use.
[0004] The utility model discloses a wall-mounted telescopic mechanism that can meet different leg lengths, which includes a base, a seat back frame that can recline relative to the base, a seat back frame driving member for driving the seat back frame to rotate and recline, a calf rest that can rotate relative to the seat back frame, and a calf rest driving member for driving the calf rest to rotate and lift. The characteristics are as follows: A telescopic frame is further provided on the seat back frame, and a telescopic driving member for driving the telescopic frame to extend and retract along the length direction of the base is provided. The calf rest is rotatably arranged on the telescopic frame and extends and retracts synchronously with it.
[0005] Adopting the above technical solution, during use, the seat back frame driving member can drive the seat back frame to recline. Further, the calf rest driving member can drive the calf rest to rotate and lift. At this time, since the calf rest rotates around a circumference, the overall length of the calf rest cannot be adjusted. At this time, by the relative extension and retraction of the telescopic frame, the position of the calf rest can be adjusted, thereby indirectly adjusting the length of the calf rest, so as to be suitable for people with different leg lengths to use. And when the telescopic frame extends and retracts, the seat depth can also be changed.
[0006] A further setting of the utility model: An installation frame is provided on the seat back frame, a guide rail is provided on the installation frame, the telescopic frame is guided and slid on the guide rail, the telescopic driving member is an electric push rod, the electric push rod is hinged on the telescopic frame, and the output end of the electric push rod is hinged on the installation frame.
[0007] Adopting the above technical solution, the guide of the guide rail can make the telescopic frame more stable when extending and retracting, and the hinged setting is convenient for the installation of the electric push rod and the adaptive change of the angle of the electric push rod during operation.
[0008] A further setting of the present utility model: A guide groove is provided at a position corresponding to the guide rail on the telescopic frame, and balls for reducing friction are further provided between the inner wall of the guide rail and the guide groove.
[0009] By adopting the above technical solution, the friction when the telescopic frame slides can be reduced, and the noise can also be reduced.
[0010] A further setting of the present utility model: A plurality of balls are arranged horizontally, and the notch position of the guide groove is bent to form a limiting plate. The balls are located above the limiting plate, and a blocking plate is arranged above the balls on the guide rail. The blocking plate and the limiting plate are cooperatively clamped on opposite sides of the balls.
[0011] By adopting the above technical solution, setting a plurality of balls can increase the structural stability, and the cooperation of the blocking plate, the limiting plate and the inner wall of the guide groove can prevent the balls from shifting. Moreover, the limiting plate can be hooked under the balls, and the telescopic frame can be prevented from disengaging from the guide rail when sliding through the blocking of the blocking plate.
[0012] A further setting of the present utility model: A foot massage seat is further provided on the calf frame. The foot massage seat is guided to slide on the calf frame, and a massage seat driving member for driving the foot massage seat to slide is further provided. A clamping member for clamping the foot is further provided on the foot massage seat.
[0013] By adopting the above technical solution, the foot massage seat can be driven by the massage seat driving member to stretch independently, and the effect of stretching the leg muscles can be achieved through the clamping of the clamping member.
[0014] A further setting of the present utility model: The seat-back frame includes a seat cushion frame and a backrest frame. A part of the telescopic frame extends to the position of the seat-back frame and can slide outwards to increase the seat depth.
[0015] By adopting the above technical solution, the seat depth can be adjusted by the telescopic movement of the telescopic frame, which can further meet the needs of customers with different leg lengths. BRIEF DESCRIPTION OF THE DRAWINGS
