By rotating the rotary control member to wind up the wire ropes to pull the movable locking members to disengage the convex cards from the slots to achieve unlocking, and releasing the rotary control member to release the wound wire ropes under the action of the elastic member.

[0007] The unlocking mechanism of the present application realizes unlocking by winding up the wire ropes through the rotary control member, with fewer parts, simplifies the structure and the transmission mechanism, reduces the manufacturing cost and the assembly difficulty, improves the smoothness of adjustment, has good stability, high reliability, reduces the failure rate, and improves the service life.

[0008] Furthermore, the first ends of the two wire ropes are connected to the adjustment frame, and the rotary control member is configured with a driving part that acts on the two wire ropes when rotating. Through the rotary control member, the user can conveniently realize operations such as pulling, tightening or releasing the wire ropes.

[0009] Furthermore, the first ends of the two wire ropes are connected to the position of the adjustment frame corresponding to the rotation center of the rotary control member, and the rotary control member is offset from the rotation center and provided with driving parts corresponding to the two wire ropes. This design ensures that the first ends of the two wire ropes are firmly connected to the adjustment frame, thus ensuring the reliability of the wire rope connection. Under normal conditions, the rotary control member is not stressed and remains in a stable state. Only when operation is required will it drive the wire ropes to move by rotation to achieve precise control. The driving part is offset from the rotation center design, increasing the moment of driving the wire ropes and making the operation more convenient.

[0010] Furthermore, the adjustment frame is configured with shaft protrusions for installing the rotary control member, the first ends of the two wire ropes are fixed by hanging on the shaft protrusions, the rotary control member is offset from the rotation center and provided with a plurality of protrusions, and driving grooves for the two wire ropes to pass through are formed between the protrusions, and both sides of the driving grooves are configured as the driving parts.

[0011] As an alternative solution, the adjusting frame structure has a shaft convex for installing a rotating control member. The first ends of two wire ropes are fixed to the shaft convex by hanging. The rotating control member is provided with a convex portion offset from the rotation center. The convex portion is provided with a driving groove through which the two wire ropes pass, and both sides of the driving groove are configured as the driving portions.

[0012] Furthermore, the shaft convex is configured on the inner top wall of the adjusting frame. The rotating control member is installed on the lower side of the two wire ropes through a shaft hole, and the driving groove is stuck on the outer sides of the two wire ropes. Adopting this design enables the first ends of the two wire ropes to be limited by the rotating control member, thus simplifying the connection structure.

[0013] Furthermore, the outer side of the positioning disk is configured with a folding portion, and the folding portion is configured with a plurality of the slots arranged indirectly. Further, the end of the folding portion is configured with a structural ring. The configuration of the folding portion and the structural ring plays a strengthening role, increasing the cooperation distance with the clamping convex, and the structural ring can effectively prevent the clamping convex from disengaging from the slot.

[0014] Furthermore, the adjusting frame includes a housing and a strengthening skeleton fixedly assembled in the housing. The strengthening skeleton extends to the connection end. Shaft seats are configured on both sides of the main body. The positioning disk is installed on the outer side of the shaft seat through a middle hole. The strengthening skeleton is configured with a shaft hole, and the shaft hole is rotatably connected to the shaft seat through a shaft convex connecting seat.

[0031] Refer to Figures 1 to 13 , an embodiment of the lower limb massager of the present application, includes a main body 1, a massage mechanism 2, an adjusting frame 3, a positioning mechanism 4 and an unlocking mechanism 5; the main body 1 is configured with two spaced-apart massage cavities 100; the massage mechanism 2 is installed on the main body 1 and acts on the massage cavity 100; both sides of the adjusting frame 3 are relatively close to each other and both ends are configured as connection ends 3.1, and the connection ends 3.1 are rotatably connected to both sides of the main body 1; the positioning mechanism 4 includes a positioning disk 4.1 fixedly connected to the main body 1 and having a plurality of radial slots 4.10 arranged on the edge, and movable locking members 4.2 installed on both sides of the adjusting frame 3, the end of the movable locking member 4.2 is configured with one or more convex cards 4.21 cooperating with the slots 4.10, and an elastic member 4.3 acting on the movable locking member 4.2 to reset it towards the positioning disk 4.1; the unlocking mechanism 5 includes a rotating control 5.1 rotatably assembled in the middle of the adjusting frame 3 and having a control part 5.1' at least partially extending out of the outside of the adjusting frame 3, and two wire ropes 5.2 arranged inside the adjusting frame 3 and having a first end 5.21 coupled to the rotating control 5.1, specifically, the first end is fixedly connected to the rotating control 5.1, and the second end 5.22 is respectively fixedly connected to the corresponding side movable locking member 4.2, by rotating the rotating control 5.1 to wind up the wire rope 5.2 to pull the movable locking member 4.2 to disengage the convex card 4.21 from the slot 4.10 to achieve unlocking, and releasing the rotating control 5.1 to release the wound-up wire rope 5.2 under the action of the elastic member 4.3.

[0032] When it is necessary to adjust the angle of the host 1, the user rotates the unlocking mechanism 5 to wind up the wire rope 5.2 through the control part 5.1', and pulls the movable locking part 4.2 to make the convex part 4.21 disengage from the slot 4.10. At this time, the adjusting frame 3 can be rotated relative to the host 1 to the required angle, such as Figure 3 the horizontal use angle shown, or Figure 4 the inclined use angle shown; of course, in some embodiments, a vertical angle can be configured, such as Figure 1 the angle shown. At this time, the adjusting frame 3 can be used as a handle for the lower limb massager, which is convenient for the user to move. When the angle of the adjusting frame 3 is adjusted, the rotation control 5.1 is released. Under the action of the elastic member 4.3, the rotation control 5.1 rotates in the reverse direction to release the wound part of the wire rope 5.2, and the convex part 4.21 of the movable locking part 4.2 plugs into the corresponding slot 4.10 to lock the adjusting frame 3 at the selected angle.

[0033] Therefore, in order to increase the range of positionable angles, a plurality of slots 4.10 can be constructed around the center of the positioning disk 4.1. It should be noted that generally, they are constructed at equal distances, which is convenient for the cooperation of the convex part 4.21.

[0034] In order to increase the stability and reliability of the locking, a plurality of convex parts 4.21 are constructed, such as 3 as shown in the attached drawings of the present application. The 3 convex parts 4.21 are spaced apart and cooperate with the three slots 4.10 on the positioning disk 4.1 at the same time.

[0035] The unlocking mechanism 5 of the present application realizes unlocking by winding up the wire rope 5.2 through the rotation control 5.1, with fewer parts, simplified structure, reduced manufacturing cost and assembly difficulty, improved smoothness of adjustment, good stability, high reliability, reduced failure rate, and increased service life.

[0036] The wire rope 5.2 of the present application is a high-strength rope, such as a steel wire rope. Of course, it can also be other existing ropes that can meet the strength requirements.

[0037] Such as Figures 1 to 4 , Figures 9 to 11 As shown, the control part 5.1' of the rotation control 5.1 extends outwards through the control hole 300 on the adjusting frame 3. It is used to rotate the rotation control 5.1 through the control part 5.1' when unlocking.

[0038] See Figures 1 to 4 , the part of the rotation control 5.1 extending out of the adjusting frame 3 faces the user side in the use state. Using the above scheme, when the adjusting frame 3 supports to the ground, the extended part of the rotation control 5.1 is located on the upper side, which is convenient for the user to operate.

[0039] Such as Figure 1 , Figure 10 AndFigure 11 As shown, the adjusting frame 3 is provided with a supporting part 3.4' in contact with the ground, which can be locally heightened, such as thickening the bending parts on both sides.

[0040] See Figures 1 to 4 , Figures 9 to 11 , at least part of the control part 5.1' is constructed as an arc. By adopting the above solution, the convenience and comfort of the user's operation can be improved. As shown in the embodiment in the attached drawing, the outer periphery of the control part 5.1' is arc-shaped. In some embodiments, the outer periphery of the control part 5.1' can be constructed with an anti-slip structure, such as patterns, concave-convex structures, etc., to increase the friction when the user operates, better transmit the driving force of the user, and prevent slipping.

[0041] See Figure 5 , Figures 9 to 13 , the first ends 5.21 of the two wire ropes 5.2 are connected to the adjusting frame 3, and the rotating control 5.1 is constructed with a driving part 5.11 that acts on the two wire ropes 5.2 during rotation. By rotating the rotating control 5.1, the user can conveniently perform operations such as pulling, tightening, or releasing the wire ropes 5.2.

[0042] In some embodiments, the first ends 5.21 of the two wire ropes 5.2 are connected to the position of the adjusting frame 3 corresponding to the rotation center of the rotating control 5.1, and the rotating control 5.1 is offset from the rotation center and provided with driving parts 5.11 corresponding to the two wire ropes 5.2. This design ensures that the first ends 5.21 of the two wire ropes 5.2 are firmly connected to the adjusting frame 3, thus ensuring the reliability of the connection of the wire ropes 5.2. Under normal conditions, the rotating control 5.1 is not stressed and remains in a stable state. Only when operation is required will it drive the wire ropes 5.2 to move by rotation to achieve precise control. The design of the driving part 5.11 being offset from the rotation center increases the torque for driving the wire ropes 5.2, making the operation more convenient.

[0043] As shown in Figure 13, hanging rings are provided at both the first end 5.21 and the second end 5.22 of the wire rope 5.2. For example, a wire rope hanging ring can be formed by clamping the end of the wire rope 5.2 bent by a metal cylinder. Of course, other technical means for fixing the end of the wire rope 5.2 to form a hanging ring can also be used, such as connection welding, connectors, etc.

[0044] See Figures 9 to 13, the adjusting frame 3 is configured with a shaft convex 3.2 for installing the rotary control 5.1. The first ends 5.21 of the two wire ropes 5.2 are fixed to the shaft convex 3.2 by hanging. The rotary control 5.1 is provided with a number of protrusions 5.10 offset from the rotation center. A driving groove 5.11' for the two wire ropes 5.2 to pass through is formed between the protrusions 5.10. Both sides of the driving groove 5.11' are configured as the driving parts 5.11. The shaft convex 3.2 serves to rotatably connect the rotary control 5.1 and at the same time ensures that the first ends 5.21 of the wire ropes 5.2 are firmly hung, enhancing the connection reliability. In addition, the protrusions 5.10 are designed with an offset to form the driving groove 5.11' for the wire ropes 5.2 to pass through, and both sides of the driving groove 5.11' constitute the driving parts 5.11. Specifically, the rotary control 5.1 is rotatably connected to the shaft convex 3.2 through a shaft hole 50. Both sides of the driving groove 5.11' are configured as the driving parts 5.11, enabling the rotary control 5.1 to wind up the wire ropes 5.2 in both forward and reverse directions, providing a good user experience.

[0045] In other embodiments (not shown), the adjusting frame 3 is configured with a shaft convex 3.2 for installing the rotary control 5.1. The first ends of the two wire ropes 5.2 are fixed to the shaft convex 3.2 by hanging. The rotary control 5.1 is provided with protrusions offset from the rotation center, and the protrusions are provided with a driving groove for the two wire ropes 5.2 to pass through. Both sides of the driving groove are configured as the driving parts.

[0046] See Figures 9 to 13 , the shaft convex 3.2 is configured on the inner top wall of the adjusting frame 3. The rotary control 5.1 is installed below the two wire ropes 5.2 through a shaft hole 50, and the driving groove 5.11' is stuck on the outside of the two wire ropes 5.2. This design limits the first ends 5.21 of the two wire ropes 5.2 by the rotary control 5.1, thus simplifying the connection structure.

[0047] In Figures 9 to 10 In the illustrated embodiment, the protrusions 5.10 are multiple arc-shaped convex walls, and the driving groove 5.11' is formed by the gap between two adjacent arc-shaped convex walls. The protrusions 5.10 are configured on the arc-shaped convex walls. When unlocking, the wire rope 5.2 is driven by the side of the driving groove 5.11'. Since the first end 5.21 and the second end 5.22 are fixed, when the rotary control 5.1 rotates, the wire rope 5.2 is wound on the outside of the arc-shaped convex walls.

[0048] On the inner wall of the adjusting frame 3, a first ring wall 3.3 is configured at a position inside the protrusions 5.10. The first ring wall 3.3 is oppositely configured with a channel 3.30 for the wire rope 5.2 to pass through along the extending direction of the adjusting frame 3. In the normal state, the driving groove 5.11' corresponds to the channel 3.30, that is, the driving part 5.11 corresponds to the outside of the channel 3.30. This is used to make the operation of the rotary control 5.1 smoother when unlocking.

[0049] In some embodiments, a second annular wall 3.4 is radially spaced outside the first annular wall 3.3. The height of the second annular wall 3.4 is lower than that of the first annular wall 3.3. The cord 5.2 passes over the top of the second annular wall 3.4, and the position of the cord 5.2 is restricted by the top of the second annular wall 3.4, thereby ensuring the smoothness when operating the rotary control 5.1.

[0050] The protrusion 5.10 is inserted into the space between the first annular wall 3.3 and the second annular wall 3.4, and the space between the first annular wall 3.3 and the second annular wall 3.4 is designed to be larger than the wall thickness of the protrusion 5.10. When the rotary control 5.1 rotates to wind up the cord 5.2, it will be received in the space between the protrusion 5.10, the first annular wall 3.3 and the second annular wall 3.4. Specifically, the radial width between the first annular wall 3.3 and the second annular wall 3.4 is preferably designed to be larger than the sum of the wall thickness of the protrusion 5.10 and the diameter of the cord 5.2.

[0051] See Figures 5 to 9 and Figure 12 As shown in, the adjustment frame 3 includes a housing 3' and a reinforcing skeleton 3.4 fixedly assembled inside the housing 3'. The reinforcing skeleton 3.4 extends to the connection end 3.1. Axle seats 1.1 are constructed on both sides of the main body 1. The positioning disk 4.1 is installed outside the axle seat 1.1 through the middle hole 40. The reinforcing skeleton 3.4 is provided with an axle hole 3.40, and the axle hole 3.40 is rotatably connected to the axle seat 1.1 through a shaft convex connection seat 1.12. The reinforcing skeleton 3.4 functions to connect the adjustment frame 3 and the main body 1 and bear forces. The first end 5.21 of the elastic member 4.3 is connected to the movable locking member 4.2, and the second end 5.22 is connected to the reinforcing skeleton 3.4, such as hanging on the hanging portion of the reinforcing skeleton 3.4. In one embodiment, the reinforcing skeleton 3.4 is made of metal sheet metal, and the movable locking member 4.2 is also made of metal sheet metal. The movable locking member 4.2 slidably cooperates with the reinforcing skeleton 3.4. It should be noted that the specific assembly structure of the reinforcing skeleton 3.4 and the movable locking member 4.2 is not an improvement of this application and can be achieved by referring to existing technical means.

[0052] See Figures 10 to 11, the outer shell 3' includes a base shell part 3.1' constructed outside the adjustment frame 3, a first inner cover part 3.2' and a second inner cover part 3.3'. The shaft convex 3.2, the first annular wall 3.3 and the second annular wall 3.4 are integrally formed on the top wall of the base shell part 3.1'. Two reinforcing skeletons 3.4 are respectively connected to both sides of the base shell part 3.1', such as by screw fixed connection. Of course, in order to enhance the connection strength, positioning convex columns and positioning holes are constructed between the two reinforcing skeletons 3.4 and the base shell part 3.1'. The first inner cover part 3.2' and the second inner cover part 3.3' respectively correspond to the middle inner side and the side inner side of the base shell part 3.1'. After the two wire ropes 5.2 and the rotation control 5.1 are assembled to the shaft convex 3.2, they are limited by the first inner cover part 3.2'. The first inner cover part 3.2' and the second inner cover part 3.3' are connected and fixed to the base shell part 3.1' by means of screws and the like.

[0053] See Figures 1 to 5 , a flexible lining 2.4 is coated on the side wall and the bottom wall of the massage cavity 100. The massage mechanism 2 includes a sole massage mechanism 2.1 installed at the bottom of the massage cavity 100, a lateral massage mechanism 2.2 installed at the side of the massage cavity 100, and a driving mechanism 2.3. One solution for the bottom massage mechanism 2.1 is a cam-type massage mechanism, and one solution for the lateral massage mechanism 2.2 is an airbag massage mechanism. Correspondingly, the driving mechanism 2.3 includes a motor and a transmission mechanism, and an air pump for controlling the airbag massage mechanism. It should be noted that the massage mechanism 2 is not an improvement of this application and will not be described in detail.

[0054] See Figures 6 to 8 , a folding part 4.11 is constructed on the outside of the positioning disk 4.1. A plurality of the slots 4.10 are indirectly arranged on the folding part 4.11. A structural ring 4.111 is constructed at the end of the folding part 4.11. The configuration of the folding part 4.11 and the structural ring 4.111 plays a strengthening role, increasing the matching distance with the clamping convex 4.21. The structural ring 4.111 can effectively prevent the clamping convex from disengaging from the slot. One embodiment of the positioning disk 4.1 is made of a metal material.

[0055] See Figures 5 to 9 , and Figure 12 , connection seats 1.1' are constructed on both sides of the main body 1.
