[0034] Reference Figure 1, the flip self-positioning mechanism, the main body is an axis assembly, which is used to position the flip part on the fixed part; the axis assembly includes an axis seat 1 locked on one side of the fixed part, an axis body 2 supporting the flip part, and a suspended limiter 3 and a rotating ring 4; the end face of the axis seat 1 is formed with an arc-shaped recessed groove 11, the suspended limiter 3 is movably arranged in the arc-shaped recessed groove 11, and a spring 5 is arranged between the two, and the spring 5 is used to maintain the tendency of the suspended limiter 3 to always convex outward; the axis body 2 passes through the axis hole of the flip part and the rotating ring 4 in turn, and the end is locked on the end face of the axis seat 1, and the rotating ring 4 is locked on one side of the flip part, and can rotate with the flip part, and the end face of the rotating ring 4 is used to contact the suspended limiter 3; one end face of the suspended limiter 3 and the rotating ring 4 is formed with a concave clamping position 31, and the other end face of the suspended limiter 3 and the rotating ring 4 is formed with a convex clamping position 41, and the convex clamping position 41 slides into the concave clamping position 31 to form positioning.

[0035] In this structure, two concave latching positions 31 are provided on one side of the suspension limit member 3, corresponding to the working state and the storage state of the flip part respectively; a protruding latching position 41 is provided on one side of the rotating member 4, and a resistance ring 42 is also provided within the radius width range occupied by the protruding latching position 41, and the resistance ring 42 is used to resist against the end face of the shaft seat 1 and the suspension limit member 3 to reduce the rotation resistance.

[0036] The suspension limiter 3 and the arc-shaped sink groove 11 are both semicircular structures, and a through hole 12 is formed at the bottom of the arc-shaped sink groove 11; a positioning column 32 corresponding to the through hole is integrally formed at the bottom of the suspension limiter 3, and the positioning column 32 passes through the end of the through hole 12 and is screwed with a limit screw 33. The limit screw head can contact the outer end surface of the through hole 12 to form a limit to prevent it from slipping out, but it does not affect its retreat by overcoming the spring force. More specifically, a positioning column 32 and a through hole 12 are correspondingly arranged in the center of the suspension limiter 3 and the arc-shaped sink groove 11, and a spring 5 is arranged at symmetrical positions on both sides of the through hole 12 to support the suspension limiter 3 in a balanced manner.

[0037] The shaft body 2 and the shaft seat 1 abut against the end surface, and are respectively formed with a matching column hole 21 and a screw column 13, as well as a convex pin 22 and a concave hole 14 for assembly indication, which not only facilitates alignment during assembly, but also improves the supporting capacity and torsion resistance of the joint between the two.

[0038] Reference Figures 2 to 7 A lower limb massager comprises a base 6, a cover 7 and a flip cover 8. The cover 7 is directly locked on the base 1 to form an integral body. The flip cover 8 is Figure 1 The flip self-positioning mechanism is positioned on the base 6, which is convenient for opening when massaging the legs. For this purpose, a massage source for the legs is arranged on the inner side of the flip cover. This is a conventional technology and does not involve any technical association, so it is omitted in the figure. A massage assembly 9 is installed on the base 6 to provide foot massage, and an opening 71 for inserting the feet is provided on the cover 7, which can independently massage the soles of the feet.

[0039] The flip cover 8 is wrapped around the top and both sides of the cover 7, and has a U-shaped notch 81 corresponding to the opening 71 of the cover, leaving both sides to form positioning arms 82, which are used to position the cover on the base 6 by flipping the shaft assembly in the self-positioning mechanism.

[0040] When only foot massage is needed, the feet can be put in and out from the opening 71 exposed by the U-shaped notch 81 without opening the flip cover. If foot massage is selected at the same time, the flip cover 8 needs to be opened and positioned in the working state so that the legs can be placed against the massage source. The top of the flip cover 8, which is the top that is opened and erected away from the positioning arm 82, has a mountain-shaped structure on its inner side and has two grooves 85 for the calves to rest against, and a massage source, such as an air bag or a mechanical massage head, or a combination of the two, is arranged in the groove 85.

[0041] like Figure 1 , Figure 4 , Figure 6 and Figure 7 , the specific positioning structure of the flip cover 8, the shaft seat 1 in the shaft assembly is locked on the base 6 through an L-shaped sheet metal part 61, the shaft seat 1 is penetrated through the reserved hole 72 of the cover, and the end face of the shaft seat 1 is convexly arranged on the outside of the reserved hole 72, that is, the cover 7 is not subjected to force; the shaft body 2 in the shaft assembly is penetrated through the shaft hole 83 on the flip cover positioning arm, and forms a rotation support for the flip cover 8; the rotating ring 4 in the shaft assembly is locked on the inner side of the positioning arm shaft hole 83, and abuts on the end face of the shaft seat 1, and cooperates with the suspension limiter 3 to form the positioning of the working position.

[0042] The end of the shaft body 2 away from the shaft seat 1 is formed with a flange 23, and the outer edge of the flange 23 is also connected with an arc-shaped tooth 24, which is used to abut against the outer end surface of the positioning arm shaft hole 83, that is, the shaft body 2 is inserted and assembled from the outside of the flip cover 8, and screwed from the outside. For this purpose, a decorative cover 86 is arranged on the shaft hole 83; the outer end surface of the shaft hole 83 is provided with a latching tooth 84 on the relative rotation track of the arc-shaped tooth 24. When the flip cover 8 is flipped to the working state, the latching tooth 84 abuts against the arc-shaped tooth 24, which can form the main support for the back flip, and bear a greater force of the leg leaning back. The suspension limiter 3 is used to prevent the flip cover 8 from accidentally flipping in the covering direction.
