DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The present invention discloses an exercise device suitable for osteoporosis patients, comprising:

[0035] Base 1: A lifting chair 6 is fixedly connected to the top of the base 1;

[0036] First exercise mechanism: The first exercise mechanism includes a mounting seat 2, a stopper 16 and a locking elastic part. Two mounting seats 2 are provided. The two mounting seats 2 are symmetrically arranged about the lifting chair 6. The two mounting seats 2 are both located above the base 1. The two mounting seats 2 are both fixedly connected to the locking elastic part. The stopper 16 is fixedly connected to the opposite side of the two mounting seats 2. The stopper 16 is provided with an arc groove on the side away from the mounting seat 2.

[0037] The second exercise mechanism: The second exercise mechanism includes a pedal 14, an adjustable elastic part and an auxiliary exercise part. Second fixed blocks 9 are fixedly connected to the two mounting seats 2. Adjustable elastic parts are installed on the top of the two second fixed blocks 9. The pedal 14 is fixedly connected to the adjustable elastic part. The auxiliary exercise part is fixedly connected to the side of the two second fixed blocks 9 away from the lifting chair 6. The auxiliary exercise part is fixedly connected to the top of the mounting seat 2 and is connected to the adjustable elastic part.

[0038] Further references Figure 1In order to improve the comfort of the user, a flexible rubber pad 17 is fixed in the arc groove.

[0039] Further references Figure 1 , 3 In order to allow the user to pedal better and avoid the foot from being separated from the pedal during the pedaling process, straps 18 are fixedly connected on both sides of the pedal 14, and buckles 19 are fixedly connected at the ends of the straps 18. The two straps 18 are detachably connected through the buckles 19.

[0040] Further references Figure 1 , 3 A plurality of anti-skid protrusions 15 are fixedly connected to the pedal 14. The anti-skid protrusions 15 can not only play an anti-skid role, but also massage the user's feet.

[0041] Further references Figure 1 , 3 The auxiliary exercise part includes a first fixed block 3, an incomplete gear 5 and a tooth plate 4. The first fixed block 3 is fixedly connected to the top of the mounting seat 2. The first fixed block 3 is located on the side of the second fixed block 9 away from the lifting chair 6. The tooth plate 4 is arranged on the side of the first fixed block 3 close to the second fixed block 9. A connecting block 26 is fixedly connected to the side of the tooth plate 4 away from the first fixed block 3. The connecting block 26 is connected to the adjustable elastic part. A second slide groove is provided on the side of the first fixed block 3 close to the second fixed block 9. A second slider 23 is slidably connected in the second slide groove. The second slider 23 is fixedly connected to the tooth plate 4. An incomplete gear 5 is arranged above the tooth plate 4. The incomplete gear 5 is meshed with the tooth plate 4. A hand grip 12 is fixedly connected to the top of the incomplete gear 5. The bottom of the hand grip 12 is hinged to the first fixed block 3.

[0042] The user holds the handle bar 12 and swings the handle bar 12, thereby driving the incomplete gear 5 to rotate around the hinge point between the handle bar 12 and the first fixed block 3. The movement of the incomplete gear 5 drives the toothed plate 4 meshing therewith to move, and the toothed plate 4 drives the adjustable elastic part to move through the connecting block 26. This arrangement not only allows the user's arms to be exercised, but also for users with weak leg strength, the adjustable elastic part can be driven to move through the arms, thereby reducing the force on the user's legs and assisting the user in leg exercise.

[0043] Further references Figure 3 , the incomplete gear 5 is a fan-shaped structure.

[0044] Further references Figure 1 , 3 In order to allow the user to better hold the handle bar 12, a non-slip cover 13 is provided on the top fixing cover of the handle bar 12.

[0045] Further references Figure 1 , 3The adjustable elastic part includes a lead screw 20 and a first spring 21. A first slide groove is provided at the top of the second fixed block 9. The first slide groove is located at the end of the second fixed block 9 close to the lifting chair 6. The lead screw 20 is rotatably connected in the first slide groove. A first slider 22, a third slider 27 and a first spring 21 are sleeved on the lead screw 20. The first slider 22 is located on the side away from the lifting chair 6. A support assembly is installed on the first slider 22. The support assembly is hinged to the second fixed block 9. The pedal 14 is fixed to the support assembly. The third slider 27 is screwed to the lead screw 20. The first slider 22 and the third slider 27 are both slidably connected to the first slide groove. The first spring 21 is located between the first slider 22 and the third slider 27, and the two ends of the first spring 21 are respectively fixed to the first slider 22 and the third slider 27. The end of the second fixed block 9 close to the lifting chair 6 is rotatably connected to the first knob 7, and the first knob 7 is coaxially fixed to the lead screw 20.

[0046] Rotating the first knob 7 drives the lead screw 20 to rotate, and the lead screw 20 drives the third slider 27 to move, thereby adjusting the pre-elastic force of the first spring 21 between the first slider 22 and the third slider 27, thereby changing the difficulty of stepping on the pedal 14 to meet the usage requirements of different users.

[0047] Further references Figure 1 , 3 The support assembly includes a bending rod 10 and a hinged rod 11. The hinged rod 11 is hinged at the top of the first slider 22, the bending rod 10 is hinged at the top of the second fixed block 9, the end of the hinged rod 11 is hinged to the middle of the bending plate, and the pedal 14 is fixed to the end of the bending rod 10.

[0048] When the pedal 14 is stepped on, the pedal 14 drives the bending rod 10 to move, the bending rod 10 drives the hinged rod 11 hinged thereto to move, and the hinged rod 11 drives the first slider 22 to overcome the elastic force of the first spring 21 and move toward the third slider 27 .

[0049] Further references Figure 3 , 4 The second fixed block 9 is fixedly connected to a fixed plate 28 and a fixed rod 35 at one end close to the lifting chair 6. The fixed plate 28 is located above the fixed rod 35. A screw 8 is rotatably connected to the fixed plate 28. A screw sleeve 29 is threadedly provided on the screw 8. The screw sleeve 29 is located below the fixed plate 28. First connecting rods 30 are hinged on both sides of the screw sleeve 29. A second connecting rod 31 is hinged at the end of the first connecting rod 30. An arc-shaped splint 32 is hinged at the end of the second connecting rod 31. The thin rod of the first knob 7 passes through the space formed by the two arc-shaped splints 32. A third connecting rod 34 is fixedly connected to the bottom end of the arc-shaped splint 32. The end of the third connecting rod 34 is hinged to the fixed rod 35.

[0050] Due to the limiting effect of the first connecting rod 30, the second connecting rod 31 and the third connecting rod 34, the screw sleeve 29 can move along the length direction of the screw rod 8. When the screw sleeve 29 moves downward, it drives the first connecting rod 30, the second connecting rod 31 and the third connecting rod 34 to work together, so that the arc clamping plate 32 clamps the thin rod of the first knob 7 to prevent the vibration generated during the movement from causing the lead screw 20 to rotate itself, thereby ensuring the stability of the preset force. When the preset force needs to be adjusted, the screw sleeve 29 moves upward so that the arc clamping plate 32 no longer clamps the thin rod of the first knob 7.

[0051] Further references Figure 4 In order to make the arc-shaped clamping plate 32 more stably limit the rotation of the knob, a friction plate 33 is fixedly connected to the inner side of the arc-shaped clamping plate 32.

[0052] Further references Figure 1 , 2 , 5, 6, 7, the locking elastic part includes a second spring 24, two third sliding grooves are provided at the top of the base 1, the two third sliding grooves are symmetrically arranged about the lifting chair 6, guide rods 25 are rotatably connected in the two third sliding grooves, the two guide rods 25 are coaxially fixed, fourth sliders 36 are slidably connected in the two third sliding grooves, a limiting hole is provided on the fourth slider 36, the two guide rods 25 respectively pass through the two fourth sliders 36 through the limiting holes, a limiting component is provided on the side of the fourth slider 36 away from the lifting chair 6, the limiting component is fixedly connected to the guide rod 25, the two mounting seats 2 are respectively fixedly connected to the two fourth sliders 36, the second spring 24 is fixedly connected to the side of the fourth slider 36 away from the lifting chair 6, the end of the second spring 24 is fixedly connected to the inner wall of the third sliding groove, the second spring 24 is sleeved on the guide rod 25, a second knob 38 is rotatably connected to the base 1, and the second knob 38 is coaxially fixedly connected to a guide rod 25.

[0053] When the second knob 38 is turned to offset the limit assembly from the limit hole, the fourth slider 36 cannot slide in the third slide groove, which can prevent the mounting base 2 from moving laterally when using the pedal 14 for training, thereby preventing the user from being injured. When it is necessary to support the mounting base 2 for lateral movement for training by the support block 16, the second knob 38 is turned to make the limit assembly correspond to the limit hole, and the fourth slider 36 can slide on the guide rod 25.

[0054] Further references Figure 5 , 6 7. The limit assembly includes a limit block 37. The limit block 37 is fixedly connected to the guide rod 25. The limit block 37 is located on the side of the fourth slider 36 away from the lifting chair 6. The shape of the combined projection of the guide rod 25 and the limit block 37 is compatible with the projection shape of the limit hole.

[0055] Further references Figure 6 There are two limit blocks 37, and the included angle between the two limit blocks 37 is 180°.

[0056] Further references Figure 2 A slideway is provided in the second knob 38, and a slide plate 40 is slidably connected in the slideway. A limiting protrusion 41 is fixedly connected to the side of the slide plate 40 close to the base 1, and the end of the limiting protrusion 41 passes through the second knob 38. A third spring 39 is fixedly connected to the side of the slide plate 40 away from the base 1, and the end of the third spring 39 is fixedly connected to the inner wall of the slideway. A limiting recess is provided on the side of the base 1 close to the second knob 38, and the limiting recess is adapted to the end of the limiting protrusion 41.

[0057] By providing the limiting protrusion 41 and the limiting recess, the rotation angle of the second knob 38 can be conveniently limited, thereby ensuring that the limiting block 37 can lock or release the fourth slider 36 .

[0058] Furthermore, two limiting recesses are provided, the two limiting recesses are arranged along the circumferential direction, and the two limiting recesses form an angle of 90°.

[0059] Instructions for use: When the user needs to step on the pedal 14 for leg training, the locking elastic part is locked to prevent the mounting seat 2 from moving laterally, the preset force of the adjustable elastic part is adjusted, and then the user sits on the lifting chair 6 and steps on the pedal 14 with his legs to overcome the elastic force of the adjustable elastic part to achieve the training purpose. If the user's leg strength is weak, the arm is used to drive the auxiliary adjustment part to move, and then drive the adjustable elastic part to move, so as to relieve the force on the patient's legs. At the same time, the user's arm can also be trained. At the same time, the auxiliary adjustment part can also be used alone to train the arm. When the user needs to use the leg to drive the mounting seat 2 to move laterally through the stop block 16 for training, the locking elastic part is no longer locked, and then training can be carried out.
