Description

Technical Field

[0001] This invention relates to the field of sarcopenia physiotherapy equipment technology, and more particularly to a physiotherapy device for sarcopenia. Background Technology

[0002] Because of insufficient muscle strength, patients with sarcopenia are prone to fatigue after a short period of exercise or standing. Therefore, their rest patterns during exercise differ from those of normal people, as standing is also a burden for them, and they can only rest by sitting. However, this way of resting during exercise affects the circulation of qi and blood in the body, which is not conducive to the recovery of muscle fatigue. In particular, the parts that come into contact with the seat are more likely to cause problems such as obstructed qi and blood circulation and lactic acid accumulation, which is not conducive to the sustainability of exercise for patients with sarcopenia. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a physiotherapy device for sarcopenia, which can improve blood circulation, accelerate muscle fatigue recovery, and increase exercise duration when used by sarcopenia patients.

[0004] This invention discloses a physiotherapy device for sarcopenia, comprising a box body with an opening at the top, a sliding plate slidably connected inside the box body, the sliding plate being able to move up and down along the inner wall of the box body, and a support frame mounted on the upper end of the sliding plate; it also includes a rotating sleeve body, a gear, and a shaft. The rotating sleeve body includes a gear portion, and the gear and support frame are fitted onto the outer wall of the shaft, with the gear and support frame slidably connected. The support frame is rotatable along the outer wall of the shaft, and the gear and support frame are distributed left and right along the axial direction of the shaft. A torsion spring is connected between the end face of the gear and the end face of the support frame, the torsion spring being fitted into the shaft and its two ends being fixed to the end face of the gear and the end face of the support frame, respectively. The second gear is located below the first gear and above the gear section, and meshes with both the first and second gears. It also includes a rotating sleeve, with a support frame corresponding to the rotating sleeve. The outer wall of the rotating sleeve has a ratchet section. A movable component is installed on the side of the support frame near the rotating sleeve. The movable component includes a movable rod, which can abut against the ratchet section and drive the rotating sleeve to rotate counterclockwise when it moves downward. It also includes a rocker arm, which abuts against the rotating sleeve to limit its clockwise rotation. When the support frame moves to its upper limit position, the top of the support frame is higher than the top of the second support frame. When the support frame moves to its lower limit position, the top of the support frame is lower than the top of the second support frame.

[0005] Furthermore, multiple movable components are distributed vertically and horizontally along the outer wall of the support frame. The movable components also include a fixed block. The movable rod is hinged to the fixed block. When the movable rod moves downward, the end of the movable rod away from the hinge point can be inserted into the ratchet part. A spring is fixedly installed on the movable rod. One end of the spring is fixedly connected to the movable rod, and the other end of the spring is fixedly connected to the support frame.

[0006] Furthermore, the swing arm is hinged to the support shaft, and the end of the swing arm away from the support shaft is inserted into the ratchet part. The support shaft is equipped with limit block one and limit block two, which are located on both sides of the swing arm swing direction. The swing arm is equipped with spring two, one end of spring two is fixed to the swing arm, and the other end of spring two is fixed to limit block two.

[0007] Furthermore, the outer wall of the support frame 2 is provided with wall surface 1 and wall surface 2. When wall surface 1 is rotated to the upper end, its top position is lower than the top position of wall surface 2 when it is rotated to the upper end.

[0008] Furthermore, the second wall surface is curved.

[0009] Furthermore, when the main body of the rotating sleeve rotates, gear one rotates, while support frame two remains stationary under the action of external force, so that the torsion spring generates torque.

[0010] Furthermore, when support frame one moves to its upper limit position, the external force acting on support frame two is reduced or removed, so that the torsion spring drives support frame two to rotate.

[0011] Furthermore, the support frame moves from its upper limit position to its lower limit position, and the main body of the rotating sleeve rotates 180 degrees.

[0012] Furthermore, binding ropes are installed on both sides of the outer wall of the box.

[0013] The beneficial effects of this invention are:

[0014] By slightly lifting the user with support frame one, the pressure exerted on the user by support frame two is released, preventing prolonged contact between support frame two and the user that could obstruct blood circulation at the contact point. By moving support frame one downwards again, the user once again contacts and sits on wall surface two. This process is repeated, causing wall surface two and the top of support frame one to alternately press on the user, creating a pressing effect. This allows patients with sarcopenia to improve blood circulation, accelerate muscle fatigue recovery, and increase exercise duration when using the physiotherapy device in this embodiment during exercise and rest.

Detailed Implementation

[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a physiotherapy device for sarcopenia includes a box body 1, which is rectangular in shape and has a cavity inside. The upper end of the box body 1 is open, and a sliding plate 2 is slidably connected inside the box body 1. The outer wall size of the sliding plate 2 matches the inner wall of the box body 1, and the sliding plate 2 can move up and down along the inner wall of the box body 1. An electric cylinder 3 is connected to the bottom of the sliding plate 2 and is installed on the inner bottom surface of the box body 1.

[0026] like Figure 1 As shown, a support frame 21 is installed on the upper end of the slide plate 2. The bottom of the support frame 21 is fixed to the upper end of the slide plate 2. The box body 1 includes two oppositely arranged side walls 11, and multiple support frames 21 are spaced apart along the length of the side walls 11. Figure 5 The support frame 21 is a long, block-shaped structure. When the support frame 21 moves upward to its limit position, the top of the support frame 21 extends out of the box body 1.

[0027] like Figure 5As shown, a shaft 4 is installed between the two side walls 11. Both ends of the shaft 4 are inserted into and fixed to the two side walls 11. A rotating sleeve 41 is fitted onto the outer wall of the shaft 4. A support frame 21 is correspondingly positioned with the rotating sleeve 41. The rotating sleeve 41 is slidably connected to the shaft 4 and can rotate along the outer wall of the shaft 4. The rotating sleeve 41 is located between the two side walls 11. Figure 6 The rotating sleeve 41 includes a gear part 411 and a rotating sleeve body 412. A gear 61 is meshed on the upper part of the gear part 411. The gear 61 is installed on the shaft body 6. The shaft body 6 is inserted into the side wall 11 and fixed. The gear 61 is inserted into the shaft body 6 and can rotate along the outer wall of the shaft body 6. A gear 51 is meshed on the upper part of the gear 61. The gear 51 is installed on the shaft body 5. The two ends of the shaft body 5 are inserted into the side walls 11 and fixed. The gear 51 can rotate along the outer wall of the shaft body 5. The gear part 411 rotates so that the gear 61 and the gear 51 rotate synchronously.

[0028] like Figure 5 As shown, a support frame 2 53 is also installed on the outer wall of the shaft 2 5. The support frame 2 53 is fitted into the shaft 2 5 and can rotate along the outer wall of the shaft 2 5. A torsion spring 52 is installed between the left end face of the support frame 2 53 and the right end face of the gear 1 51. The two ends of the torsion spring 52 are fixed to the end face of the gear 1 51 and the end face of the support frame 2 53, respectively.

[0029] like Figure 2 As shown, the support frame 2 53 includes two opposing wall surfaces 1 531 and two opposing wall surfaces 2 532. Wall surface 1 531 is a plane, and wall surface 2 532 is an arc surface. Figure 1 A comparison was made between two states in which wall surface 1 531 and wall surface 2 532 rotate to the top of support frame 2 53, respectively. The top position of wall surface 1 531 when it rotates to the top of support frame 2 53 is lower than the top position of wall surface 2 532 when it rotates to the top of support frame 2 53.

[0030] like Figure 2 As shown, the outer wall of the main body 412 of the rotating sleeve is provided with a ratchet portion 4121, which is arranged circumferentially along the outer wall of the main body 412 of the rotating sleeve, and the ratchet portion 4121 is a ratchet structure. Combined with... Figure 5 The side wall 11 is equipped with a support shaft 7, and is combined with Figure 4A rocker arm 71 is hinged to the support shaft 7. The rocker arm 71 can swing along the hinge point, and the swing surface is parallel to the rotation surface of the rotating sleeve body 412. The rocker arm 71 is located below the rotating sleeve body 412, and the end of the rocker arm 71 away from the support shaft 7 is inserted into and abuts against the ratchet part 4121. The support shaft 7 is equipped with a first limit block 72 and a second limit block 73, which are located on both sides of the swing direction of the rocker arm 71. A second spring 74 is installed on the rocker arm 71. One end of the second spring 74 is fixed to the rocker arm 71, and the other end of the second spring 74 is fixed to the second limit block 73. When the main body 412 of the rotating sleeve rotates counterclockwise, the rocker arm 71 rotates clockwise, the rocker arm 71 separates from the first limiting block 72, and the second spring 74 is compressed. When the main body 412 of the rotating sleeve rotates clockwise, the rocker arm 71 inserts into and abuts against the main body 412 of the rotating sleeve, and the rocker arm 71 abuts against the first limiting block 72 to restrict the clockwise rotation of the main body 412 of the rotating sleeve.

[0031] like Figure 2 , Figure 3 As shown, a movable component 211 is installed on the right side wall of the support frame 21. Multiple movable components 211 are distributed at intervals along the outer wall of the support frame 21. The movable component 211 includes a fixed block 2111, which is fixedly connected to the support frame 21. A movable rod 2112 is hinged to the fixed block 2111 via a hinge shaft 2113. A spring 2114 is fixedly installed on the movable rod 2112. One end of the spring 2114 is fixedly connected to the movable rod 2112, and the other end of the spring 2114 is fixedly connected to the support frame 21.

[0032] When the movable rod 2112 moves downward, the end of the movable rod 2112 away from the hinge point can be inserted into the ratchet part 4121. The spring 2114 pulls the movable rod 2112, allowing the movable rod 2112 to push the rotating sleeve body 412 downward, causing the rotating sleeve body 412 to rotate counterclockwise by a certain angle. This causes the gear 51 to rotate by a corresponding angle under the action of the gear part 411. (Combined) Figure 5 Since a torsion spring 52 is fixed between the second support frame 53 and the first gear 51, after the first gear 51 rotates a certain angle, if the second support frame 53 is controlled by an external force to not rotate, the torsion spring 52 will generate torque. When the external force controlling the second support frame 53 is removed, the second support frame 53 will rotate.

[0033] When the movable lever 2112 moves upward, the ratchet part 4121 pushes the movable lever 2112 away, the spring 1 2114 is compressed, and the movable lever 2112 does not exert a pushing effect on the ratchet part 4121 to rotate.

[0034] like Figure 1As shown, straps 12 are installed on both sides of the bottom of the box 1, which are used to fix the box 1 to the seat. In use, in the initial state, the support frame 21 is at its upper limit position, the wall surface 532 faces upwards, and the top of the support frame 21 is higher than the top of the wall surface 532. The user sits on the support frame 21. After the device is started, as shown... Figure 8 As shown, support frame 21 moves downward to its lower limit position, at which point the top of support frame 21 is lower than the top of support wall surface 532. During the downward movement of support frame 21, support frame 21 detaches from the user, who then sits on support wall surface 532. As support frame 21 moves downward to its lower limit position, the movable component 211 causes the rotating sleeve 412 to rotate 180 degrees counterclockwise, which in turn causes gear 51 to rotate 180 degrees under the action of gear part 411. At this time, the pressure of the user on support wall surface 532 restricts the rotation of support frame 53. Since a torsion spring 52 is fixed between support frame 53 and gear 51, the torsion spring 52 generates torque when twisted by gear 51. As the support frame 21 moves upward to its upper limit position under the drive of the electric cylinder 3, the rotating sleeve 412 does not rotate clockwise due to the contact between the swing rod 71 and the limiting block 72. The movable rod 2112 is pushed open by the ratchet part 4121, and the spring 2114 is compressed. The movable rod 2112 does not push the ratchet part 4121 to rotate, so the gear 51 does not rotate, and the corresponding torsion spring 52 maintains its torque state. When the support frame 21 moves upward until its top position is higher than the top of the wall surface 532, the support frame 21 slightly lifts the user, creating a pressing effect. At the same time, the pressure exerted by the user on the wall surface 532 decreases and is not enough to further restrict the rotation of the support frame 53. Under the action of the torsion spring 52, the support frame 53 twists and rotates 180 degrees. Figure 7As the second support frame 53 rotates until the first wall surface 531 faces upwards, the sudden increase in distance between the second support frame 53 and the user reduces the resistance exerted by the user on the second support frame 53 when supporting the second wall surface 532. Furthermore, the rotational speed of the second support frame 53 under the torque of the torsion spring 52 increases, allowing the second support frame 532, located on the opposite side of the rotation direction of the first wall surface 531, to have sufficient force to overcome the resistance exerted by the user and rotate to the top position. At this point, the torsion spring 52 returns to its initial state and generates no torque. Therefore, by slightly lifting the user with the first support frame 21, the pressure exerted by the second support frame 53 on the user is released, preventing prolonged contact between the second support frame 53 and the user that could obstruct blood circulation at the contact point. As the support frame 21 moves downward again, the user comes into contact with the wall surface 532 again and sits on the wall surface 532. The above process is repeated so that the wall surface 532 and the top of the support frame 21 alternately press on the user, forming a pressing effect. This allows patients with sarcopenia to improve their blood circulation, accelerate muscle fatigue recovery, and increase exercise duration when using the physiotherapy device in this embodiment during exercise and rest.

[0035] Due to the curved surface of the second wall 532, the rotation of the second wall 532 during the rotation of the second support frame 53 produces a stroking effect on the contact area between the user and the second support frame 53, which is also beneficial to the circulation of qi and blood.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
