Detailed implementation mode

[0033] An automatic massage fitness bed according to the present invention, as Figure 1 shown, includes a fixed frame 1, which is installed on the ground. Universal wheels can also be installed at the bottom of the fixed frame 1 to facilitate the movement of the overall device. As Figure 5 shown, a horizontally arranged rectangular frame 11 is installed at the upper end of the fixed frame 1. A massage roller 12 arranged along its width direction is installed on the rectangular frame 11. A transverse movement frame 13 that can move along the length direction of the rectangular frame 11 is installed in cooperation with the outer periphery of the rectangular frame 11. A connecting cloth 14 is installed between the two ends of the transverse movement frame 13. The connecting cloth 14 covers the upper side of the massage roller 12. During use, the user only needs to lie on the connecting cloth 14. The transverse movement frame 13 is connected with a reciprocating movement mechanism 2, and the reciprocating movement mechanism 2 can drive the transverse movement frame 13 to reciprocate on the outer periphery of the rectangular frame 11. The reciprocating movement mechanism 2 can be an existing crank and connecting rod mechanism, cam mechanism, or Geneva mechanism.

[0034] During the transverse movement of the transverse movement frame 13, the connecting cloth 14 thereon and the user move horizontally together. Under the action of the user's gravity, the connecting cloth 14 is pressed on the massage roller 12. Since the massage roller 12 is installed on the rectangular frame 11, the rectangular frame 11 and the massage roller 12 thereon do not move horizontally. When the connecting cloth 14 and the massage roller 12 move relatively horizontally, the massage roller 12 will rotate to massage the user's back.

[0035] At both ends of the transverse movement frame 13, a cervical and lumbar traction device 7 is installed, which can stretch and traction the lumbar and cervical vertebrae of the user. As Figure 6 and Figure 7 shown, the cervical and lumbar traction device 7 includes a foot stretching device installed at the rear end of the transverse movement frame 13, an armpit fixing device and a neck stretching device installed at the front end of the transverse movement frame 13. Among them, the foot stretching device includes a square tube 71 fixed on the transverse movement frame 13. An L-shaped tube 72 that can move along it is fitted inside the square tube 71. One end of the L-shaped tube 72 is located inside the square tube 71, and a foot clamping wheel 73 is installed at the other end of the L-shaped tube 72. A first rotating handle 74 is also installed on the square tube 71. Rotating the first rotating handle 74 can adjust the position of the L-shaped tube 72 inside the square tube 71. The foot clamping wheels 73 on the L-shaped tube 72 are in two rows to facilitate clamping the user's ankle. The L-shaped tube 72 between the two rows of foot clamping wheels 73 can also adopt a telescopic structure to further adjust the up and down position of the foot clamping wheels 73, which is convenient for users of different body types.

[0036] The armpit fixing device includes two vertical rods 75 fixed at the front end of the transverse movement frame 13. A longitudinal rotating shaft 76 is provided between the two vertical rods 75. Longitudinal moving sleeves 77 are fitted at both ends of the longitudinal rotating shaft 76, and armpit positioning rods 78 are installed on the longitudinal moving sleeves 77. The neck stretching device includes a wire winding pin 79 fixed on the longitudinal rotating shaft 76. The wire winding pin 79 is located between the longitudinal moving sleeves 77. One end of the longitudinal rotating shaft 76 passes through the vertical rod 75 and a second rotating handle 710 is installed. Rotating the second rotating handle 710 can make the wire winding pin 79 rotate without the longitudinal moving sleeve 77 rotating.

[0037] When using the cervical and lumbar traction device 7, first rotate the armpit positioning rod 78 and the longitudinal moving sleeve 77 around the longitudinal rotating shaft 76 until the armpit positioning rod 78 is located on the connecting cloth 14, so that the armpit positioning rod 78 is located on both sides of the user's armpits to fix it. Then rotate the first rotating handle 74 to extend the foot clamping wheels 73, so that the user's feet can easily extend into the foot clamping wheels 73. Then rotate the first rotating handle 74 in the reverse direction to pull the foot clamping wheels 73 away from the armpit positioning rod 78. On the premise that the armpit positioning rod 78 is relatively fixed, the above process is to stretch and traction the user's lumbar vertebrae. A cervical traction belt is used in cooperation with the neck stretching device. The user wears the cervical traction belt, and then hangs and fixes the connecting rope of the cervical traction belt on the wire winding pin 79. Rotating the second rotating handle 710 can make the wire winding pin 79 wind the connecting rope to traction and stretch the user's cervical vertebrae. The setting of the longitudinal moving sleeve 77 can ensure that the longitudinal rotating shaft 76 and the armpit positioning rod 78 rotate respectively. When adjusting the cervical vertebra stretching, it will not affect the position of the armpit positioning rod 78, and the mutual rotation will not interfere with each other.

[0038] Further, as Figure 5 shown, roller bearings 115 are installed on both sides of the rectangular frame 11. A transverse movement chute 116 that mates with the roller bearings 115 is formed inside the transverse movement frame 13. A plastic plate for reducing friction can also be installed in the transverse movement chute 116, which can reduce friction and minimize noise generation to the greatest extent.

[0039] Further, to facilitate the installation of the massage rollers 12, as Figure 8 shown, convex platforms 15 are provided on both sides of the inner circumference of the rectangular frame 11. A first vertical plate 16 is installed on the convex platforms 15. Mounting holes 17 that mate with the rotating shafts of the massage rollers 12 are formed in the first vertical plate 16. The massage rollers 12 are located on the first vertical plates 16 on both sides. To enable the massage rollers 12 to conform to the spinal curve of the user's back, a second vertical plate 18 is further provided on the outer side of the first vertical plate 16. The height of the second vertical plate 18 is higher than that of the first vertical plate 16. The massage rollers 12 are installed between the second vertical plates 18 on both sides, and the position of the second vertical plate 18 on the outer side of the first vertical plate 16 can be adjusted as required, so that the massage rollers 12 arranged in a staggered manner can conform to the spinal curve of the user's back and improve the overall massage effect. In addition, a flat plate 19 is installed at the front end between the first vertical plates 16 on both sides. The above-mentioned first vertical plate 16, second vertical plate 18, and flat plate 19 are all located below the connecting cloth 14. The setting of the flat plate 19 can replace some of the massage rollers 12. During the reciprocating massage process of the user, the flat plate 19 is designed to prevent the position of the head from being too low, resulting in increased intracranial pressure, and can prevent unnecessary side effects for users with high blood pressure or brain discomfort during the massage process.

[0040] To enable this device to adapt to users of different heights, as Figure 9 shown, a fixed pipe 117 is installed at the bottom of the flat plate 19. The fixed pipe 117 mates with the mounting holes 17. Both the flat plate 19 and the massage rollers 12 can move back and forth according to the user's body height. Among them, there are mainly three rows of massage rollers 12, which are used to massage the shoulders, back, waist, and legs at the same time. The massage rollers 12 can move up and down to the most comfortable height according to different body shapes. The second vertical plate 18 can be replaced with different height types to meet the above requirements. A massage roller 12 is also installed at the front end of the flat plate 19, which can prevent friction between the connecting cloth 14 and the flat plate 19. At the same time, moving the position of this massage roller 12 can also function to adjust the tightness of the connecting cloth 14. Different height headrests can also be placed on the flat plate 19 as required to increase comfort. The headrest is placed on the connecting cloth 14 at the position of the flat plate 19 and directly contacts the user's head.

[0041] Further, as Figure 10As shown, in order to facilitate the disassembly and fixing of the connecting cloth 14, one end of the connecting cloth 14 is fixed on the transverse movement frame 13. A sleeve 110 is installed at the other end of the connecting cloth 14. Sleeves 111 are fitted at both ends of the sleeve 110. The sleeve 111 is fixedly installed with a locking bolt 112. A positioning ring 113 matched with the locking bolt 112 is installed on the transverse movement frame 13. A locking nut 114 is also fitted on the locking bolt 112. After the locking bolt 112 extends into the positioning ring 113 and then is tightened with the locking nut 114, the connecting cloth 14 can be locked. The overall structure is simple, the positioning is firm and it is convenient for disassembly and assembly.

[0042] Another connection method of the connecting cloth 14 is as Figure 11 shown. One end of the connecting cloth 14 is fixed on the transverse movement frame 13. A sleeve 110 is installed at the other end of the connecting cloth 14. Locking and positioning tubes 118 with internal threads are installed at both ends of the sleeve 110. A connecting plate 119 is provided on the transverse movement frame 13. A locking and positioning screw 120 is provided on the connecting plate 119. The locking and positioning screw 120 is matched with the locking and positioning tube 118, which is convenient for adjusting the tightness of the connecting cloth 14.

[0043] Furthermore, in order to ensure that when the foot stretching device performs lumbar stretching, hard traction on the lumbar spine is avoided, a buffer device is installed between the square tube 71 and the transverse movement frame 13. The buffer device includes a mounting plate 711 fixed at the rear end of the transverse movement frame 13. A square hole 712 matched with the square tube 71 is opened on the mounting plate 711. Guide rods 713 are fixed on the mounting plate 711 on both sides of the square hole 712. Guide holes 714 matched with the guide rods 713 are opened on both sides of the square tube 71. Springs 715 are installed on the outer periphery of the guide rods 713. Washers 716 are sleeved on the guide rods 713 between the springs 715 and the square tube 71. The square tube 71 can move a certain distance relative to the mounting plate 711 and is not directly fixed on the transverse movement frame 13. When the foot stretching device performs lumbar stretching, the overall device has a moving distance within the compressible range of the spring 715, which can play a buffering role during the traction and stretching process. Washers 716 can also be sleeved on the guide rods 713. The number of washers 716 can be added as required. When encountering a user with a particularly tall height and the adjustment screw stroke of the L-shaped tube 72 is insufficient, increasing the number of washers 716 can move the square tube 71, the L-shaped tube 72 and the foot clamping wheel 73 backward to meet the usage requirements. Fixing screws and washers can be installed on the guide rods 713. Screws can be provided between the mounting plate 711 and the transverse movement frame 13 to facilitate disassembly and fixing.

[0044] Furthermore, the armpit positioning rod 78 can be telescopically adjusted to facilitate adjusting the armpit fixing position according to the requirements of the user. As Figure 12As shown, a positioning gear 717 is coaxially installed on a longitudinal rotating shaft 76 between a second rotating handle 710 and a vertical rod 75. A positioning pin 718 that cooperates with the positioning gear 717 is also installed on the vertical rod 75. After the neck stretching device is adjusted to a desired appropriate position, the positioning pin 718 is pushed out to enter the positioning gear 717 for positioning, which can prevent the longitudinal rotating shaft 76 from rotating and enable the neck stretching device to maintain traction stretching treatment at this position.

[0045] Further, in order to position the longitudinal displacement sleeves 77 on both sides, a limiting sleeve 719 is sleeved on the outer periphery of the longitudinal rotating shaft 76 between the longitudinal displacement sleeves 77. The limiting sleeve 719 is fixedly installed on the longitudinal rotating shaft 76 through a wire winding pin 79. The setting of the limiting sleeve 719 can limit the longitudinal displacement sleeves 77 on both sides, so that the axilla positioning rod 78 does not move longitudinally on the longitudinal rotating shaft 76 and can only rotate around the longitudinal rotating shaft 76. Among them, the limiting sleeve 719 fixedly connected to the longitudinal rotating shaft 76 can also rotate together with the longitudinal rotating shaft 76 to adjust the cervical traction stretching position, acting on the axilla fixing device and the neck stretching device respectively, and the structure is simple and easy to manufacture. At the same time, the action processes of the two will not interfere with each other.

[0046] An abdominal massage device 6 is also installed on the rectangular frame 11, as Figure 13 shown. The abdominal massage device 6 includes U-shaped tubes 61 installed on both sides of the rectangular frame 11. The U-shaped tubes 61 are arranged vertically. Positioning holes 62 are opened on the U-shaped tubes 61 along their height directions. Positioning rods 63 are installed in the positioning holes 62 in a matching manner. Abdominal massage rollers 64 are installed on the two positioning rods 63. Counterweight blocks can be added or subtracted at both ends of the abdominal massage rollers 64 as needed to achieve a weight loss effect. The abdominal massage rollers 64 can move up and down along the U-shaped tubes 61. The above-mentioned abdominal massage device 6 is equivalent to being fixed on the rectangular frame 11 without moving. When the user located on the connecting cloth 14 moves back and forth, the abdominal massage rollers 64 on the positioning rods 63 drop to the user's abdomen under the action of gravity, and there is a certain rising space above the abdominal massage rollers 64. As the user moves back and forth, the abdominal massage device 6 will rotate along with the abdominal curve of the user, thereby achieving the purpose of massage.

[0047] Further, in order to adjust the position of the U-shaped tubes 61 on the rectangular frame 11 as needed, transverse sliding rods 65 are fixedly installed on both sides of the rectangular frame 11. For the convenience of installation, the transverse sliding rods 65 can be directly installed on the longitudinal insertion plate 49. A transverse displacement sliding sleeve 66 that cooperates with the transverse sliding rods 65 is provided at the bottom of the U-shaped tubes 61, as Figure 14As shown in the figure, a guiding convex block 67 arranged along the length is provided at the bottom of the horizontal sliding rod 65. A guiding groove 68 matched with the guiding convex block 67 is formed at the bottom of the transverse sliding sleeve 66. A positioning screw 69 is further installed on the transverse sliding sleeve 66. Rotating the positioning screw 69 can fix the transverse sliding sleeve 66 on the horizontal sliding rod 65. The arrangement of the guiding convex block 67 and the guiding groove 68 plays a guiding role in the movement of the U-shaped tube 61 and can ensure that the U-shaped tube 61 always remains in a vertical state when moving on the horizontal sliding rod 65.

[0048] As Figure 15 shown in the figure, the reciprocating movement mechanism 2 includes a motor 21 and a turntable 22 installed on the fixed frame 1. The output shaft of the motor 21 is connected to the turntable 22 through a conveyor belt 23. A connecting rod 24 is provided on the turntable 22. One end of the connecting rod 24 is hinged to the turntable 22, and the other end of the connecting rod 24 is hinged to the transverse movement frame 13. The arrangement of the turntable 22 and the connecting rod 24 is similar to that of a crank and connecting rod, and can drive the transverse movement frame 13 to perform reciprocating movement under the drive of the motor 21. The motor 21 can adjust the movement speed according to different requirements.

[0049] Furthermore, in order to adjust the transmission ratio between the turntable 22 and the connecting rod 24 and adjust the length distance of the reciprocating movement of the transverse movement frame 13, as Figure 16 shown in the figure, at least two hinge seats 25 are installed along the diameter position of the turntable 22. The connecting rod 24 is connected to the hinge seat 25 through a spherical hinge 26. The hinge seats 25 at different diameter lengths can drive the connecting rod 24 to drive the transverse movement frame 13 to perform reciprocating movement at different distances. In order to prevent the spherical hinge 26 from changing the angle during rotation and affecting the connection stability of the connecting rod 24, a turning hinge 27 is further installed between the connecting rod 24 and the spherical hinge 26 to ensure that the spherical hinge 26 can still maintain the transmission coherence with the connecting rod 24 during rotation and prevent the connecting rod 24 from generating bending and torsion deformation.

[0050] The present invention can also be installed with a timing device to control the working time of the motor. The user can set the activity duration through the control panel or the remote control, and it can automatically stop after the activity time ends.

[0051] The technical solution of the present invention is not limited within the scope of the embodiments described in the present invention. The technical content not elaborately described in the present invention is all well-known technologies.
