Detailed implementation mode

[0027] A multifunctional fitness bed according to the present invention, as Figure 1 shown, includes a fixed frame 1. The fixed frame 1 is installed on the ground, and universal wheels can also be installed at the bottom of the fixed frame 1 to facilitate the movement of the overall device. As Figure 5As shown in the figure, a horizontally arranged rectangular frame 11 is installed at the upper end of the fixed frame 1. A massage roller 12 is installed on the rectangular frame 11 and arranged along its width direction. A transverse movement frame 13 that can move along the length direction of the rectangular frame 11 is fitted and installed on the outer periphery of the rectangular frame 11. A connecting cloth 14 is installed between the two ends of the transverse movement frame 13, and 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 to 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 - connecting rod mechanism, cam mechanism or Geneva mechanism.

[0028] During the transverse movement of the transverse movement frame 13, the connecting cloth 14 on it and the user move horizontally together. Under the action of the user's gravity, the connecting cloth 14 is pressed against 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 on it do not move horizontally. When the connecting cloth 14 and the massage roller 12 move relatively horizontally, the massage roller 12 will rotate, massaging the user's back.

[0029] As Figure 6 shown in the figure, an arm stretching device 3 is also installed at the front end of the transverse movement frame 13 to facilitate the user's flexion, extension, lifting and lowering exercises of the upper limbs. The arm stretching device 3 includes a first U - shaped frame 31 hinged at both sides of the transverse movement frame 13. A first longitudinal rotating shaft 32 is installed at the front end of the fixed frame 1. The two sides of the first U - shaped frame 31 are respectively connected to the first longitudinal rotating shaft 32 through first connecting rods 33. One end of the first connecting rod 33 is hinged on the first U - shaped frame 31, and the other end of the first connecting rod 33 is fixed on the first longitudinal rotating shaft 32.

[0030] Among them, the first longitudinal rotating shaft 32 on the arm stretching device 3 is relatively fixed to the fixed frame 1, and the bottom of the first U - shaped frame 31 is installed on the transverse movement frame 13 and can move horizontally with it. When the transverse movement frame 13 moves to the right in the Figure 2 shown direction, the hinged position at the bottom of the first U - shaped frame 31 moves to the right together, and the first connecting rod 33 rotates counter - clockwise around the first longitudinal rotating shaft 32. As the transverse movement frame 13 continuously moves to the right, it gradually pushes the first U - shaped frame 31 to swing to the left in the Figure 2 shown direction. When the transverse movement frame 13 moves to the left, the first connecting rod 33 rotates clockwise around the first longitudinal rotating shaft 32. As the transverse movement frame 13 continuously moves to the left, it gradually pushes the first U - shaped frame 31 to swing to the right. Driven by the reciprocating movement mechanism 2, the arm stretching device 3 can complete the reciprocating swing to both sides. When the user's upper limb grasps the first U - shaped frame 31, the flexion, extension, lifting and lowering exercises of the upper limb are completed.

[0031] Further, in order to enable the height position of the first U-shaped frame 31 to meet the needs of users with different arm lengths, such as Figure 7 As shown, at the bottoms of both sides of the first U-shaped frame 31, first sliding sleeves 37 are cooperatively installed. First positioning holes 34 which are matched with each other are formed in both the first sliding sleeves 37 and the first U-shaped frame 31. One end of the first sliding sleeve 37 is hinged to the transverse movement frame 13, and the other end of the first sliding sleeve 37 is fixedly connected to the first U-shaped frame 31. By adjusting the positions of different first positioning holes 34 between the first sliding sleeve 37 and the first U-shaped frame 31, the height of the overall first U-shaped frame 31 can be adjusted as required, and thus the needs of users with different arm lengths can be met.

[0032] Further, in order to enable the arm lifting device 3 to swing with different amplitudes during the reciprocating movement of the transverse movement frame 13, such as Figure 8 As shown, second sliding sleeves 35 which are matched with the first connecting rods 33 are installed at both ends of the first longitudinal rotating shaft 32. Second positioning holes 36 which are matched with each other are formed in both the second sliding sleeves 35 and the first connecting rods 33. One end of the first connecting rod 33 is hinged to the first sliding sleeve 37, and the other end of the first connecting rod 33 is fixedly connected to the second sliding sleeve 35. By adjusting the length distance that the first connecting rod 33 extends out of the second sliding sleeve 35 to adjust the hinged length distance between the first U-shaped frame 31 and the first longitudinal rotating shaft 32, the reciprocating swing amplitude of the first U-shaped frame 31 can be adjusted during the reciprocating movement of the transverse movement frame 13, so as to meet different exercise amounts during the upper limb flexion and extension exercise.

[0033] Such as Figure 9 As shown, a four-limbs flat-opening swing device 4 is installed at the bottom of the transverse movement frame 13. When the user lies on the connecting cloth 14, the upper limbs and lower limbs on both sides can be placed on the four-limbs flat-opening swing device 4 and driven by the reciprocating movement mechanism 2 to perform reciprocating flat-opening movement of the four limbs. The four-limbs flat-opening swing device 4 includes a first mounting frame 41 installed at the front end of the bottom of the transverse movement frame 13 and a second mounting frame 42 installed at the rear end of the bottom of the transverse movement frame 13. First vertical rotating shafts 43 are installed on both sides of the first mounting frame 41, and hand swing arms 44 are installed on the first vertical rotating shafts 43. A pull ring 45 is installed at one end of the hand swing arm 44 extending out of the transverse movement frame 13, and the user holds the pull ring 45 with the hand to play a role in fixing the arm. Second vertical rotating shafts 46 are installed on both sides of the second mounting frame 42, and leg swing arms 47 are installed on the second vertical rotating shafts 46. A leg placing plate 48 is installed at one end of the leg swing arm 47 extending out of the transverse movement frame 13 for placing the feet or calves of the user. Such as Figure 10As shown, longitudinal insertion plates 49 are fixedly installed on both sides of the rectangular frame 11. Avoidance grooves 410 that match the longitudinal insertion plates 49 are formed on the transverse movement frame 13. A positioning folding plate 411 is installed at one end of the longitudinal insertion plate 49 that passes through the avoidance groove 410. The positioning folding plate 411 is arranged along the length direction of the transverse movement frame 13. Second connecting rods 412 are provided between the positioning folding plate 411 and the hand swing arm 44, and between the positioning folding plate 411 and the leg swing arm 47. One end of the second connecting rod 412 is hinged to the positioning folding plate 411, and the other end of the second connecting rod 412 is hinged to the swing arm. The reciprocating movement mechanism 2 is connected to the transverse movement frame 13 through a first mounting bracket 41.

[0034] The horizontal swing structures of the above-mentioned hand swing arm 44 and leg swing arm 47 are the same. Here, the structure of the hand swing arm 44 is used to explain its movement process in detail. One end of the hand swing arm 44 is installed on the first mounting bracket 41 through a first vertical rotating shaft 43. Since the first mounting bracket 41 is fixedly installed on the transverse movement frame 13, one end of the hand swing arm 44 hinged to the first mounting bracket 41 can follow the transverse movement frame 13 to reciprocate. A second connecting rod 412 is also connected between the hand swing arm 44 and the positioning folding plate 411. Among them, the positioning folding plate 411 is fixedly installed on the rectangular frame 11. The second connecting rod 412 installed between the positioning folding plate 411 and the hand swing arm 44 is equivalent to hinging a connection point position of the hand swing arm 44 to the rectangular frame 11. The overall connection condition of the hand swing arm 44 is equivalent to one end being fixed and the other end swinging. During the reciprocating movement of the transverse movement frame 13, the hand swing arm 44 swings around the position hinged to the second connecting rod 412 as the center point. Taking Figure 3 the direction shown as an example, when the transverse movement frame 13 moves to the right, the hand swing arm 44 rotates clockwise around the position hinged to the second connecting rod 412. When the transverse movement frame 13 moves to the left, the hand swing arm 44 rotates counterclockwise around the position hinged to the second connecting rod 412. When the transverse movement frame 13 reciprocates, the hand swing arm 44 simultaneously makes a reciprocating horizontal swing. The swing structure principle of the leg swing arm 47 is the same as the above. Driven by the reciprocating movement mechanism 2, the hand swing arm 44 and the leg swing arm 47 can simultaneously make a reciprocating horizontal swing.

[0035] As Figure 11As shown in the figure, in order to adapt to the different arm lengths of users and enable stretching operations of the upper limb on the hand swing arm 44, a stretching adjustment device is installed on the hand swing arm 44. The stretching adjustment device includes a telescopic rod 429 fixedly installed on the hand swing arm 44. The telescopic rod 429 can be controlled by a lead screw nut mechanism to adjust the distance that the telescopic rod 429 extends out of the hand swing arm 44. A first fixed sleeve 413 is installed on the telescopic rod 429. A screw rod 414 is installed in the first fixed sleeve 413 in a matching manner. A first rotating handle 415 is installed at one end of the screw rod 414 extending out of the first fixed sleeve 413. A nut sleeve 416 is installed in a matching manner at the other end of the screw rod 414. A limit block 417 is installed on the screw rod 414 near the first rotating handle 415 at one end in the first fixed sleeve 413. A pull ring 45 is fixedly installed on the nut sleeve 416. After the user's hand grasps the pull ring 45, rotating the first rotating handle 415 can drive the nut sleeve 416 and the pull ring 45 to retract, thereby stretching the user's upper limb.

[0036] As Figure 28 shown in the figure, the lead screw nut mechanism between the telescopic rod 429 and the hand swing arm 44 includes a fixed sleeve 431 installed in the hand swing arm 44. A positioning sleeve 432 is installed at one end of the fixed sleeve 431. A positioning hole matching the positioning sleeve 432 is provided on the hand swing arm 44. A positioning pin is installed in the positioning hole to fix the fixed sleeve 431 in the hand swing arm 44 through the positioning sleeve 432. A nut is installed at the other end of the fixed sleeve 431. A support plate 433 is provided on the outer periphery of the nut. The support plate 433 fits with the internal space of the hand swing arm 44 to prevent the position of the nut from shifting. A screw rod is installed in the nut in a matching manner. A positioning nut 434 is installed at the other end of the screw rod. A screw rod fixing plate 435 is provided at the end of the telescopic rod 429. A through hole matching the screw rod is provided on the screw rod fixing plate 435. A keyway is provided at the end of the screw rod passing through the through hole. The middle part is threaded and a rotating handle is installed. The wheel handle on the rotating handle can be folded up when not in use. When the rotating handle rotates, it can drive the telescopic rod 429 to telescopically move in the hand swing arm 44.

[0037] As Figure 31 shown in the figure, in order to avoid hard injury to the upper limb during the stretching process, a buffering function is added in the first fixed sleeve 413. A plug is provided at the front end of the first fixed sleeve 413. A bolt is screwed at the rear end of the nut sleeve 416. The bolt fixes a gasket at the rear end of the first fixed sleeve 413. A buffer spring is provided on the outer periphery of the first fixed sleeve 413. The buffer spring is located between the gasket and the plug. Pulling the first fixed sleeve 413 to move can compress the buffer spring, thereby playing a buffering role.

[0038] Furthermore, as Figure 12As shown in the figure, in order to adapt to the different lengths of the user's lower limbs, a second fixing sleeve 418 is installed on the leg swing arm 47. A telescopic tube 419 is fitted inside the second fixing sleeve 418. A leg placement plate 48 is fixedly installed on the telescopic tube 419. A long slot 420 arranged along its length is formed at the bottom of the second fixing sleeve 418. A long convex block 421 matched with the long slot 420 is installed on the telescopic tube 419. The arrangement of the long slot 420 and the long convex block 421 can prevent the leg placement plate 48 from rotating during the stretching process, so that the leg placement plate 48 always faces upward to support the user's legs. A stretching adjustment device can also be installed on the leg swing arm 47, and the traction of the user's legs can also be completed in cooperation with the traction foot sleeve.

[0039] Further, in order to enable the four - limb swing - out device 4 to meet the differences between the upper and lower limbs of different users, the distance between the first mounting bracket 41 and the second mounting bracket 42 can be adjusted. The first mounting bracket 41 is fixedly installed on the transverse movement frame 13. As Figure 13 shown, corresponding to the position of the second mounting bracket 42, slideways 422 are provided inside both sides of the transverse movement frame 13. A horizontally arranged lead screw 423 is fixedly installed on the first mounting bracket 41. A nut 430 matched with the lead screw 423 is installed on the second mounting bracket 42. One end of the lead screw 423 passing through the first mounting bracket 41 is provided with a second rotating handle 424. The other end of the lead screw 423 is fixed to the second mounting bracket 42 through the nut 430. Rotating the second rotating handle 424 can make the second mounting bracket 42 move relative to the transverse movement frame 13 on the slideways 422, thereby adjusting the distance between the first mounting bracket 41 and the second mounting bracket 42, so that the distance between the hand swing arm 44 and the leg swing arm 47 meets the requirements of the differences between the upper and lower limbs of the user.

[0040] Further, as Figure 14 shown, a third positioning hole 425 is formed along the length direction of the positioning folding plate 411. Fourth positioning holes 426 are formed along the length directions of the hand swing arm 44 and the leg swing arm 47. One end of the second connecting rod 412 can be hinged in cooperation with the third positioning hole 425, and the other end of the second connecting rod 412 can be hinged in cooperation with the fourth positioning hole 426. By selecting the second connecting rod 412 to be hinged in cooperation with the third positioning holes 425 and the fourth positioning holes 426 at different positions, the reciprocating swing amplitude of the hand swing arm 44 and the leg swing arm 47 can be adjusted to meet the different exercise volume requirements of the user.

[0041] When only the stretching and traction function of the four - limb flat - opening swing device 4 is required, without requiring the hand swing arm 44 and the leg swing arm 47 to follow the reciprocating movement of the transverse movement frame 13, it is only necessary to disconnect the connection between the swing arm and the positioning folding plate 411, connect all the swing arms to the transverse movement frame 13, so that the swing arm only follows the movement of the transverse movement frame 13 without swinging. A positioning plate 427 parallel to the positioning folding plate 411 is installed on the transverse movement frame 13. A fifth positioning hole 428 is opened along the length direction of the positioning plate 427. The fifth positioning hole 428 can cooperate with the fourth positioning hole 426 for positioning. When the fifth positioning hole 428 and the fourth positioning hole 426 are in positioning cooperation, the whole swing arm is equivalent to being installed on the transverse movement frame 13 and will not swing. The cooperation between the fifth positioning hole 428 and the fourth positioning hole 426 can use the second connecting rod 412 or an existing countersunk bolt that cooperates with the fifth positioning hole 428 and the fourth positioning hole 426.

[0042] As Figure 15 shown, 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 third connecting rod 24 is provided on the turntable 22. One end of the third connecting rod 24 is hinged to the turntable 22, and the other end of the third connecting rod 24 is hinged to the first mounting frame 41. The turntable 22 and the third connecting rod 24 are arranged similar to a crank - connecting rod, and can drive the first mounting frame 41 and 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.

[0043] Further, in order to adjust the transmission ratio between the turntable 22 and the third connecting rod 24 and adjust the length distance of the reciprocating movement of the transverse movement frame 13, at least two hinge seats 25 are installed along the diameter position of the turntable 22. The third connecting rod 24 is connected to the hinge seat 25 through a ball joint 26. The hinge seats 25 at different diameter lengths can drive the third connecting rod 24 to drive the transverse movement frame 13 to perform reciprocating movement at different distances. In order to prevent the angle of the ball joint 26 from changing during rotation, thus affecting the connection stability of the third connecting rod 24, a flipping hinge 27 is also installed between the third connecting rod 24 and the ball joint 26 to ensure that the ball joint 26 can still maintain the transmission coherence with the third connecting rod 24 during rotation and prevent the third connecting rod 24 from generating bending and torsion deformation.

[0044] Further, for the convenience of installing the massage roller 12, as Figure 16As shown in the figure, on both sides of the inner circumference of the rectangular frame 11, there are convex platforms 15. On the convex platforms 15, there are first vertical plates 16 installed. On the first vertical plates 16, there are installation holes 17 that match the rotating shafts of the massage rollers 12. The massage rollers 12 are located on the first vertical plates 16 on both sides. In order to make the massage rollers 12 conform to the back spinal curve of the user, on the outer side of the first vertical plates 16, there are also second vertical plates 18. The height of the second vertical plates 18 is higher than that of the first vertical plates 16. Between the second vertical plates 18 on both sides, there are massage rollers 12 installed, and the position of the second vertical plates 18 on the outer side of the first vertical plates 16 can be adjusted as needed, so that the massage rollers 12 arranged in a scattered height can conform to the back spinal curve of the user and improve the overall massage effect. In addition, at the front end between the first vertical plates 16 on both sides, there is also a flat plate 19 installed. The above-mentioned first vertical plates 16, second vertical plates 18, and flat plate 19 are all located under the connecting cloth 14. The setting of the flat plate 19 can replace part 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, causing increased cranial pressure, and can prevent unnecessary side effects for users with high blood pressure or brain discomfort during the massage process. In order to make this device adaptable to users of different heights, such as Figure 26 As shown in the figure, at the bottom of the flat plate 19, there is a fixed tube 117 installed. The fixed tube 117 matches the installation hole 17. Both the flat plate 19 and the massage rollers 12 can move back and forth according to the body height of the user. 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 plates 18 can be replaced with different height types to meet the above requirements. At the front end of the flat plate 19, there is also a massage roller 12 installed, which can prevent the connecting cloth 14 from rubbing against the flat plate 19. At the same time, moving the position of this massage roller 12 can also play a role in adjusting the tightness of the connecting cloth 14. On the flat plate 19, headrests of different heights can also be placed according to requirements to increase comfort. The headrest is placed on the connecting cloth 14 at the position of the flat plate 19 and directly contacts the head of the human body.

[0045] Furthermore, as shown in Figure 17 the figure, in order to facilitate the disassembly, assembly, and fixation of the connecting cloth 14, one end of the connecting cloth 14 is fixed on the transverse movement frame 13. At the other end of the connecting cloth 14, there is a sleeve 110 installed. At both ends of the sleeve 110, there are sleeves 111 installed in a matching manner. The sleeves 111 are fixedly installed with locking bolts 112. On the transverse movement frame 13, there is a positioning ring 113 that matches the locking bolts 112. On the locking bolts 112, there are also locking nuts 114 installed in a matching manner. After the locking bolts 112 extend into the positioning ring 113 and then are tightened in cooperation with the locking nuts 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.

[0046] Another connection method of the connecting cloth 14 is as shown inFigure 29 As shown, one end of the connecting cloth 14 is fixed on the transverse movement frame 13, and a sleeve 110 is installed at the other end of the connecting cloth 14. Locking and positioning tubes 118 with internal screw threads are installed at both ends of the sleeve 110. A connecting plate 119 is provided on the transverse movement frame 13, and a locking and positioning screw 120 is provided on the connecting plate 119. The locking and positioning screw 120 cooperates with the locking and positioning tube 118 to facilitate adjusting the tightness of the connecting cloth 14.

[0047] Further, as Figure 5 shown, roller bearings 115 are installed on both sides of the rectangular frame 11. Transverse movement chutes 116 that cooperate with the roller bearings 115 are provided inside the transverse movement frame 13. Plastic plates for reducing friction can also be installed in the transverse movement chutes 116, which can reduce friction and minimize the generation of noise to the greatest extent while.

[0048] A leg massage device 5 is installed at the rear end of the transverse movement frame 13, which can be used by the user to complete swinging massage in a lower limb inverted position, deep squat exercises for the knee joint and hip joint, and massage the legs and the soles of the feet. As Figure 18 shown, the leg massage device 5 includes a second U-shaped frame 51 hinged at both sides of the transverse movement frame 13. A second longitudinal rotating shaft 52 is installed at the rear end of the fixed frame 1. The two sides of the second U-shaped frame 51 are respectively connected to the second longitudinal rotating shaft 52 through fourth connecting rods 53. One end of the fourth connecting rod 53 is hinged on the second U-shaped frame 51, and the other end of the fourth connecting rod 53 is fixed on the second longitudinal rotating shaft 52. Leg massage rollers 54 are also installed between the two sides of the second U-shaped frame 51.

[0049] Among them, the second longitudinal rotating shaft 52 on the leg massage device 5 is relatively fixed to the fixed frame 1, and the bottom of the second U-shaped frame 51 is installed on the transverse movement frame 13 and can move horizontally with it. When the transverse movement frame 13 moves Figure 2 right in the direction shown, the hinged position at the bottom of the second U-shaped frame 51 also moves right, and the fourth connecting rod 53 rotates clockwise around the second longitudinal rotating shaft 52. As the transverse movement frame 13 continuously moves right, it gradually pushes the second U-shaped frame 51 to swing left in the Figure 2 direction shown. When the transverse movement frame 13 moves left, the fourth connecting rod 53 rotates counterclockwise around the second longitudinal rotating shaft 52. As the transverse movement frame 13 continuously moves left, it gradually pushes the second U-shaped frame 51 to swing right. Driven by the reciprocating movement mechanism 2, the leg massage device 5 can complete reciprocating swinging to both sides. When the user's legs are placed on the massage rollers 54, the flexion, extension, lifting and lowering exercises of the lower limbs can be completed.

[0050] Further, in order to enable the height position of the second U-shaped frame 51 to meet the needs of users with different leg lengths, as Figure 19As shown, third sliding sleeves 55 are fitted and installed at the bottoms on both sides of the second U-shaped frame 51. Sixth positioning holes 511 which match each other are formed in both the third sliding sleeves 55 and the second U-shaped frame 51. One end of each third sliding sleeve 55 is hinged to the transverse movement frame 13, and the other end of each third sliding sleeve 55 is fixedly connected to the second U-shaped frame 51. By adjusting the positions of different sixth positioning holes 511 between the third sliding sleeves 55 and the second U-shaped frame 51, the height of the overall second U-shaped frame 51 can be adjusted as required, thereby meeting the needs of users with different leg lengths.

[0051] Further, in order to enable the leg massage device 5 to swing by different amplitudes during the reciprocating movement of the transverse movement frame 13, as Figure 20 shown, fourth sliding sleeves 56 which match the fourth connecting rods 53 are installed at both ends of the second longitudinal rotating shaft 52. Seventh positioning holes 57 which match each other are formed in both the fourth sliding sleeves 56 and the fourth connecting rods 53. One end of each fourth connecting rod 53 is hinged to the fourth sliding sleeve 56, and the other end of each fourth connecting rod 53 is fixedly connected to the fourth sliding sleeve 56. By adjusting the length of the fourth connecting rod 53 extending out of the fourth sliding sleeve 56 to adjust the hinged length between the second U-shaped frame 51 and the second longitudinal rotating shaft 52, the reciprocating swing amplitude of the second U-shaped frame 51 can be adjusted during the reciprocating movement of the transverse movement frame 13, meeting different exercise amounts during the lower limb flexion and extension exercise.

[0052] Further, in order to adjust the height position of the leg massage rollers 54 as required to facilitate the massage of the user's legs or the soles of the feet, fifth sliding sleeves 58 which match the two side edges of the second U-shaped frame 51 are installed at both ends of the leg massage rollers 54. Eighth positioning holes 59 which match each other are formed in both the fifth sliding sleeves 58 and the second U-shaped frame 51. By selecting eighth positioning holes 59 with different height positions for matching, the height position of the leg massage rollers 54 on the second U-shaped frame 51 can be adjusted to meet the needs of users of different heights. A bent beam 510 which inclines forward is further provided at the upper end of the second U-shaped frame 51. The setting of the bent beam 510 increases the space for the user's leg activities to facilitate exercises such as knee bending and leg stretching.

[0053] An abdominal massage device 6 is installed on the rectangular frame 11, as Figure 21As shown in the figure, 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 vertically arranged. A ninth positioning hole 62 is provided on the U-shaped tube 61 along its height direction. A positioning rod 63 is fitted and installed in the ninth positioning hole 62. Abdominal massage rollers 64 are installed on the positioning rods 63 on both sides. Counterweights are added to both ends of the abdominal massage rollers 64. The abdominal massage rollers 64 can move up and down along the U-shaped tubes 61. The above-mentioned abdominal massage device 6 is fixed on the rectangular frame 11 and does not move. 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. 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, thus achieving the purpose of massage.

[0054] Further, in order to adjust the position of the U-shaped tube 61 on the rectangular frame 11 as required, 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 movement sliding sleeve 66 is provided at the bottom of the U-shaped tube 61 and is matched with the transverse sliding rods 65. As Figure 22 shown, a guiding convex block 67 is arranged at the bottom of the transverse sliding rod 65 along its length. A guiding groove 68 matched with the guiding convex block 67 is provided at the bottom of the transverse movement sliding sleeve 66. A positioning screw 69 is also installed on the transverse movement sliding sleeve 66. Rotating the positioning screw 69 can fix the transverse movement sliding sleeve 66 on the transverse 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 transverse sliding rod 65.

[0055] A cervical and lumbar traction device 7 is installed at both ends of the transverse movement frame 13, which can stretch and traction the lumbar and cervical vertebrae of the user. As Figure 23 and Figure 24 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 and installed in 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 third rotating handle 74 is also installed on the square tube 71. Rotating the third 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 arranged in two rows to facilitate clamping the user's ankle part. The L-shaped tube 72 between the two rows of foot clamping wheels 73 can also adopt a telescopic structure, so as to adjust the up and down position of the foot clamping wheels 73, which is convenient for users of different body types.

[0056] The axilla fixing device includes two vertical rods 75 fixedly installed at the front end of the transverse moving frame 13. A third longitudinal rotating shaft 76 is arranged between the two vertical rods 75. Longitudinal moving sleeves 77 are fitted and installed at both ends of the third longitudinal rotating shaft 76. An axilla positioning rod 78 is installed on the longitudinal moving sleeve 77. The neck stretching device includes a wire winding pin 79 fixed on the third longitudinal rotating shaft 76. The wire winding pin 79 is located between the longitudinal moving sleeves 77. One end of the third longitudinal rotating shaft 76 passes through the vertical rod 75 and is installed with a fourth rotating handle 710. Rotating the fourth rotating handle 710 can make the wire winding pin 79 rotate without the longitudinal moving sleeve 77 rotating.

[0057] When using the cervical and lumbar traction device 7, first rotate the axilla positioning rod 78 and the longitudinal moving sleeve 77 around the third longitudinal rotating shaft 76 until the axilla positioning rod 78 is located on the connecting cloth 14, so that the axilla positioning rod 78 is located on both sides of the user's axilla to fix it. Then rotate the third rotating handle 74 to make the foot clamping wheel 73 extend, so that the user's foot can easily extend into the foot clamping wheel 73. Then rotate the third rotating handle 74 in the reverse direction to pull the foot clamping wheel 73 away from the axilla positioning rod 78. On the premise that the axilla positioning rod 78 is relatively fixed, the above process can stretch and traction the user's lumbar spine. 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 to the wire winding pin 79. Rotating the fourth rotating handle 710 can make the wire winding pin 79 wind the connecting rope to traction and stretch the user's cervical spine. The setting of the longitudinal moving sleeve 77 can ensure that the third longitudinal rotating shaft 76 and the axilla positioning rod 78 rotate respectively. When adjusting the cervical spine stretching, it will not affect the position of the axilla positioning rod 78, and the mutual rotation will not interfere with each other.

[0058] Further, to ensure that the foot stretching device avoids rigid traction on the lumbar spine during lumbar spine stretching, 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 to the rear end of the transverse movement frame 13. A square hole 712 matching the square tube 71 is provided 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 matching the guide rods 713 are provided on both sides of the square tube 71. A first spring 715 is installed on the outer periphery of the guide rod 713, and a washer 716 is sleeved on the guide rod 713 between the first spring 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 to the transverse movement frame 13. When the foot stretching device performs lumbar spine stretching, the overall device has a moving distance within the compressible range of the first spring 715, which can play a buffering role during the traction stretching process. A washer 716 can also be sleeved on the guide rod 713, and the number of washers 716 can be added as needed. 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 rod 713, and screws can be provided between the mounting plate 711 and the transverse movement frame 13 for easy disassembly and fixing.

[0059] Further, the armpit positioning rod 78 can be telescopically adjusted to facilitate adjusting the position of armpit fixation according to the requirements of the user. As Figure 25 shown, a positioning gear 717 is coaxially installed on a third longitudinal rotating shaft 76 between the fourth rotating handle 710 and the vertical rod 75. A positioning pin 718 matching the positioning gear 717 is also installed on the vertical rod 75. After the neck stretching device is adjusted to the required appropriate position, the positioning pin 718 is pushed out to enter the positioning gear 717 for positioning, which can prevent the third longitudinal rotating shaft 76 from rotating and keep the neck stretching device in this position for traction stretching treatment.

[0060] Further, to position the longitudinal movement sleeves 77 on both sides, a limiting sleeve 719 is sleeved on the outer periphery of the third longitudinal rotating shaft 76 between the longitudinal movement sleeves 77. The limiting sleeve 719 is fixedly installed on the third longitudinal rotating shaft 76 through a wire winding pin 79. The setting of the limiting sleeve 719 can limit the longitudinal movement sleeves 77 on both sides, so that the armpit positioning rod 78 does not move longitudinally on the third longitudinal rotating shaft 76 and can only rotate around the third longitudinal rotating shaft 76. The limiting sleeve 719 fixedly connected to the third longitudinal rotating shaft 76 can also rotate together with the third longitudinal rotating shaft 76 to adjust the cervical traction stretching position, acting on the armpit fixing device and the neck stretching device respectively, with a simple structure and easy to manufacture, and there will be no interference in the action processes of the two.

[0061] The fixation between the second sliding sleeve 35 and the first connecting rod 33, and between the fourth sliding sleeve 56 and the fourth connecting rod 53 can be directly achieved by a positioning pin, or by a Figure 27 pin positioning device as shown. The pin positioning device includes a vertical plate 81 fixedly installed on the sliding sleeve. On the vertical plate 81, a first guiding cylinder 82 and a second guiding cylinder 83 are concentrically installed. An L-shaped pin 84 is fitted and installed in the first guiding cylinder 82 and the second guiding cylinder 83. A vertical groove 85 matching with the L-shaped pin 84 is formed on the side wall of the first guiding cylinder 82. The L-shaped pin 84 can drop onto the second guiding cylinder 83 and cooperate with the positioning hole in the sliding sleeve for positioning. When it is necessary to release the positioning, only need to lift the L-shaped pin 84 onto the first guiding cylinder 82, and then rotate it by a certain angle so that the upper end of the L-shaped pin 84 is separated from the vertical groove 85 and rests on the upper part of the first guiding cylinder 82.

[0062] Furthermore, in order to facilitate the L-shaped pin 84 to automatically enter the second guiding cylinder 83 when it is separated from the first guiding cylinder 82, and to prevent the second guiding cylinder 83 located in the second guiding cylinder 83 from being separated due to vibration or external force, etc., as Figure 30 shown, a vertical guiding sleeve 86 is installed on the first guiding cylinder 82. A second spring 87 is installed in the vertical guiding sleeve 86. A vertical rod 88 is provided at the top of the L-shaped pin 84. A limiting plate 89 is installed on the outer periphery of the vertical rod 88. The second spring 87 is located on the outer periphery of the vertical rod 88 above the limiting plate 89 and always has a tendency to push the L-shaped pin 84 downward. When it is necessary to release the fixation between the second sliding sleeve 35 and the first connecting rod 33, and between the fourth sliding sleeve 56 and the fourth connecting rod 53, overcome the elastic force of the second spring 87 and lift the L-shaped pin 84 onto the first guiding cylinder 82. When it is necessary to perform fixation, rotate the L-shaped pin 84 to the position of the vertical groove 85. Under the action of the elastic force of the second spring 87, the L-shaped pin 84 will be pushed into the second guiding cylinder 83 for positioning, and due to the elastic force of the second spring 87, the L-shaped pin 84 will not easily be separated from the second guiding cylinder 83.

[0063] The present invention can also be equipped 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.

[0064] 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 described in detail in the present invention is all well-known technologies.
