[0014] The following is a detailed description of the specific implementation of the utility model in conjunction with the accompanying drawings:
[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0016] The utility model discloses a suspended movable guide rail frame structure, including a base. In the implementation case of the utility model, it includes a first arc guide rail frame 21 fixedly arranged on the base 1 and a second arc guide rail frame 22 that can slide back and forth relative to the base 1. The first arc guide rail frame 21 and the second arc guide rail frame 22 are combined to form a swing track 2. The swing track 2 on the base 1 is provided with two groups and is arranged opposite to each other. The first arc guide rail frame 21 and the second arc guide rail frame 22 are arranged in sequence along the front and rear directions and are relatively staggered left and right. The base 1 is also provided with an adjusting electric push rod 3 for driving the second arc guide rail frame 22 to slide back and forth.
[0017] The above technical solution is adopted and assembled into an electric massage chair or a massage sofa. At this time, the seat frame of the massage chair is located between the two sets of rocking tracks 2. At this time, by arranging support rollers on the seat frame, one set of support rollers is arranged corresponding to the first arc guide frame 21, and one set is arranged corresponding to the second arc guide frame 22, so that the seat frame can be suspended and supported. The first arc guide frame 21 and the second arc guide frame 22 cooperate to form a rocking track for rocking guidance and limiting of the seat frame, and the rocking track will be approximately arc-shaped. When the electric push rod 3 is adjusted to work and the distance between the first arc guide frame 21 and the second arc guide frame 22 is shortened, the total length of the rocking track is relatively reduced, and the travel of the seat frame remains unchanged. At this time, the seat frame can be swung to a higher position along the rocking track, that is, the swing height will become larger, and vice versa, the swing height of the seat frame will become smaller. The swing amplitude can be adjusted by swinging within the maximum range.
[0018] The first arc guide frame 21 and the second arc guide frame 22 are both provided with arc guide rails 4. At this time, the supporting rollers can be located in the arc guide rails 4 to support the seat frame to be relatively floating and relatively swingable, which can facilitate the installation and support of the seat frame.
[0019] The base 1 is provided with transverse guide rails 5 at positions corresponding to the second arc-shaped guide rail frames 22. The transverse guide rails 5 are provided with at least two groups along the transverse direction. The second arc-shaped guide rail frames 22 are provided with support rollers 6 for rotation corresponding to the transverse guide rails 5. The plurality of transverse guide rails 5 can prevent the second arc-shaped guide rail frames 22 from rotating relative to each other, thereby better guiding the second arc-shaped guide rail frames 22 to slide forward and backward. When the second arc-shaped guide rail frames 22 slide forward and backward, not only can the swing amplitude be adjusted, but also the function of lying down in zero space can be realized.
[0020] Both ends of the arc-shaped guide rail 4 are opened to form an assembly opening 7, and an anti-detachment cover 8 is provided on the assembly opening 7 (the anti-detachment cover 8 is most preferably fixed by bolts, but can also be fixed by welding, and the anti-detachment cover 8 is most preferably provided with an arc-shaped avoidance surface). The assembly opening 7 can facilitate the support roller 6 to enter the arc-shaped guide rail 4, thereby simplifying the difficulty of assembly, and blocking it through the anti-detachment cover 8, thereby preventing the support roller 6 from detaching from the arc-shaped guide rail 4.
[0021] The second arc-shaped guide rail frame 22 between the two sets of swing rails 2 is connected with a connecting rod 9. One end of the adjusting electric push rod 3 is hinged on the base 1, and the other end is hinged on the connecting rod 9. The stability effect is better during movement, and there will be no adjustment time error.
