DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all, based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0032] As Figures 1-3 Indicated, the utility model provides a kind of walking machine core that massage head can open and close, including rack 1, rack 1 is slidably provided with massage machine core, and massage machine core includes shell 2 and is set on shell 2 massage head 3, walking machine core further includes position changing mechanism:

[0033] Position changing mechanism includes at least one guide part 111 and at least one adjusting assembly 4 (herein two guide parts 111 and two adjusting assemblies 4 are described as example, when corresponding two massage heads 3 can be close to each other or away from each other to open and close movement), guide part 111 is set on rack 1;

[0034] Adjusting assembly 4 includes pull rod 41, turntable 42, driving piece 44 and support rod 43;

[0035] Turntable 42 is rotationally arranged in shell 2, and one end of pull rod 41 is connected to one end of turntable 42;

[0036] Driving piece 44 is arranged at the other end of pull rod 41, and driving piece 44 passes through the bottom of shell 2 and contacts with guide part 111;

[0037] Support rod 43 is arranged at the other end of the top surface of turntable 42, and the top end of support rod 43 is provided with massage head 3;

[0038] When the massage mechanism core slides on the frame 1, the driving piece 44 moves along the guide part 111, the driving piece 44 drives the pull rod 41 to move, the pull rod 41 drives the rotating disc 42 to rotate, the rotating disc 42 drives the supporting rod 43 to rotate, so that the massage head 3 rotates around the rotating shaft of the rotating disc 42 along with the supporting rod 43, thereby changing the position of the massage head 3 on the shell 2, so that when the massage mechanism core moves, the position of the massage head 3 also changes, when a person leans on the massage head 3 of the massage mechanism core, different positions of the human body can be massaged, the massage position of the human body is increased, the experience of the person is better, and meanwhile, no additional power source is needed for driving, which is more energy-saving and environment-friendly.

[0039] When the pull rod 41 encounters an overload condition, deformation and joint loosening of the pull rod 41 may occur, thereby avoiding serious damage of the mechanism, and generally, the rotating disc 42 is driven to rotate by a power-driven gear transmission, which has no overload protection function, and once an overload occurs, the gear teeth are prone to wear and breakage, and even the entire transmission system is damaged.

[0040] By setting the pull rod 41 as an intermediate carrier, compared with directly setting the driving piece 44 on the rotating disc 42, the stress of the guide part 111 can be reduced, and by setting the pull rod 41, the rotating disc 42 and the driving piece 44 for transmission, the opening and closing movement of the massage head 3 is more stable.

[0041] As shown in Figure 1 and Figure 2 , the shell 2 comprises an upper shell 22 and a lower shell 21 which are detachably and fixedly connected, specifically by screws, so that when the driving mechanism 5 is damaged, it is convenient to overhaul, and the bottom surface of the lower shell 21 is horizontally provided with a transverse groove 211 along the direction perpendicular to the sliding direction of the massage mechanism core on the frame 1, and the driving piece 44 is slidably arranged in the transverse groove 211, by which the transverse groove 211 can ensure the same movement stroke of the massage head 3, so that the length of the transverse groove 211 is minimized, the slotting damage area of the lower shell 21 is reduced, and meanwhile, by such setting, the contact and wear stroke of the driving piece 44 with the transverse groove 211 is minimized when the driving piece 44 slides along the guide part 111.

[0042] As shown in Figure 3 , the rotating disc 42 is detachably and fixedly provided with a fixed shaft 45, the fixed shaft 45 penetrates the pull rod 41 and the bottom of the lower shell 21, and one end of the pull rod 41 is hingedly connected to the fixed shaft 45;

[0043] By such setting, the driving piece 44 slides along the guide part 111, the driving piece 44 moves in the transverse groove 211, and can drive the pull rod 41 to move, so that the pull rod 41 can drive the rotating disc 42 to rotate, and by setting the fixed shaft 45 to penetrate the bottom of the lower shell 21, the rotating disc 42 rotates more stably.

[0044] As shown in Figure 3 andFigure 4 As shown, the bottom surface of the lower shell 21 is provided with a first arc-shaped guide slot 212 and a second arc-shaped guide slot 213, the support rod 43 is slidingly arranged in the first arc-shaped guide slot 212, and the fixed shaft 45 is slidingly arranged in the second arc-shaped guide slot 213. The fixed shaft 45 here can be an axle;

[0045] By arranging the support rod 43 to move in the first arc-shaped guide slot 212 and the fixed shaft 45 to move in the second arc-shaped guide slot 213, a centering and guiding effect is further achieved, so that the rotation of the rotating disc 42 and the movement of the pull rod 41 are more stable;

[0046] As shown in Figure 3 A shaft sleeve 46 is fixed to the outer surface of the driving member 44. Since the driving member 44 not only slides in the second arc-shaped guide slot 213 but also slides in the guide portion 111, the wear of the driving member 44 is relatively more serious. Therefore, the shaft sleeve 46 can well protect the driving member 44 and prolong its service life.

[0047] As shown in Figure 2 and Figure 3 The support rod 43 is fixedly installed with a kneading gear 57 on the outer surface, and the housing 2 is provided with a driving mechanism 5 for driving the kneading gear 57 to rotate. By arranging the driving mechanism 5 to drive the kneading gear 57 to rotate, the support rod 43 is driven to rotate, and finally the rotating massage work of the massage head 3 is performed;

[0048] Specifically, the driving mechanism 5 includes a double-shaft motor 51 and two groups of first transmission gear sets. The two output ends of the double-shaft motor 51 are each fixedly installed with a worm 52. Each first transmission gear set includes a worm wheel 53, a first gear 54, a second gear 55, and a third gear 56. The worm wheel 53 and the first gear 54 are coaxially fixed and rotatably arranged on the lower shell 21. The second gear 55 and the third gear 56 are coaxially fixed and rotatably arranged on the lower shell 21. The worm wheel 53 and the worm 52 are in meshing engagement. The first gear 54 and the second gear 55 are in meshing engagement. The third gear 56 and the kneading gear 57 are in meshing engagement.

[0049] By driving the double-shaft motor 51 to drive the two worms 52 to rotate, the worm 52 drives the worm wheel 53 to rotate, the worm wheel 53 drives the first gear 54 to rotate, the first gear 54 drives the second gear 55 to rotate, the third gear 56 rotates with the second gear 55, and the third gear 56 drives the kneading gear 57 to rotate, thereby driving the support rod 43 to rotate, and finally performing the rotating massage work of the massage head 3;

[0050] By setting the size of the worm gear 53 greater than the size of the first gear 54, the size of the first gear 54 smaller than the size of the second gear 55, the size of the second gear 55 greater than the size of the third gear 56, the size of the third gear 56 smaller than the size of the kneading gear 57, the multi-stage transmission thus arranged has a large transmission ratio and a stronger output torque, avoiding limiting the rotation of the massage head 3 when the human body is too heavy and pressed on the massage head 3, and ensuring that the massage head 3 can rotate normally when the human body is pressed on the massage head 3.

[0051] As shown in Figure 3 The center points of the worm gear 53, the third gear 56 and the kneading gear 57 are arranged in a triangular shape, which can make the structural position of each gear more compact. The pull rod 41 is arc-shaped and its arc-shaped opening is directly opposite the second gear 55, which can avoid the contact and collision between the pull rod 41 and the center shafts of the second gear 55 and the third gear 56 when the pull rod 41 moves.

[0052] As shown in Figures 1-3 The walking mechanism further includes a walking gear 7 rotatably arranged on the lower shell 21 and protruding from the shell 2. The rack 12 is arranged on the frame 1 and engages with the walking gear 7. The second transmission gear set 6 is arranged in the shell 2 and includes a fourth gear 61, a fifth gear 62 and a sixth gear 63. The fourth gear 61 and the fifth gear 62 are coaxially fixed and rotatably arranged on the lower shell 21. The sixth gear 63 is coaxially fixed with the walking gear 7 and rotatably arranged on the lower shell 21. The first gear 54 engages with the fourth gear 61, and the fifth gear 62 engages with the sixth gear 63.

[0053] When the double-shaft motor 51 is started, the double-shaft motor 51 drives the worm gear 52 to rotate, the worm gear 52 drives the worm wheel 53 to rotate, the worm wheel 53 drives the first gear 54 to rotate, the first gear 54 drives the second gear 55 to rotate and simultaneously drives the fourth gear 61 to rotate, the fourth gear 61 drives the fifth gear 62 to rotate, the fifth gear 62 drives the sixth gear 63 to rotate, and the sixth gear 63 drives the walking gear 7 to rotate synchronously, so that the walking gear 7 moves along the rack 12, thereby completing the walking of the mechanism on the frame 1.

[0054] Similarly, by setting the size of the first gear 54 smaller than the size of the fourth gear 61, the size of the fourth gear 61 greater than the size of the fifth gear 62, the size of the fifth gear 62 smaller than the size of the sixth gear 63, and the size of the sixth gear 63 greater than the size of the walking gear 7, the multi-stage transmission thus arranged has a large transmission ratio and a stronger output torque, avoiding limiting the movement of the massage mechanism on the frame 1 when the human body is too heavy and pressed on the massage head 3.

[0055] As shown in Figure 1As shown, the guide part 111 is a guide groove or guide rail, symmetrically arranged on the back plate 11, and here, the guide part 111 is taken as the guide groove arranged on the back plate 11, which can reduce the overall weight on the one hand, and avoid additional guide rail on the other hand, thereby relatively lower cost.

[0056] As shown in the drawings, Figure 1 As shown, the rack 1 comprises a detachably fixed back plate 11, a vertical beam 13 and a cross beam 14, and the guide part 111 is arranged on the back plate 11.

[0057] Specifically, the back plate 11, the vertical beam 13 and the cross beam 14 are detachably fixed by screws, so as to facilitate replacement of the back plate 11 with different guide parts 111 having different trajectories, so as to meet the needs of different people for different movement strokes of the massage head 3.

[0058] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
