Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation equipment, and in particular to a scapulohumeral periarthritis rehabilitation device. Background Art

[0002] For people who do long-term high-intensity training, muscle and joint injuries often occur. Long-term high-intensity training may cause muscle fiber tearing, inflammation, and wear of joint cartilage. These injuries may cause chronic pain, arthritis, frozen shoulder and other problems.

[0003] For the treatment of frozen shoulder, rehabilitation treatment is usually carried out through a rehabilitation device after drug treatment. The rehabilitation device in the prior art mainly includes a fixing frame, a fixed pulley, a traction rope and a handle. The fixing frame is used to fix the rehabilitation device on a wall or a door, the fixed pulley is installed on the fixing frame, one end of the traction rope passes through the fixed pulley, and the traction rope is hung on the fixed pulley. Handles are fixed at both ends of the fixed pulley. The patient's normal arm reciprocates by pulling the handle to lift the diseased arm back and forth to achieve rehabilitation treatment.

[0004] However, most of the rehabilitation devices in the prior art are manual traction devices, and patients are easily discouraged from undergoing rehabilitation treatment due to fatigue. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a scapulohumeral periarthritis rehabilitation device to solve the problem in the prior art that most rehabilitation devices are manual traction and patients are easily less motivated to undergo rehabilitation treatment due to fatigue.

[0006] The present invention solves the above technical problems by the following technical means: A scapulohumeral periarthritis rehabilitation device comprises a mounting frame, a driving wheel, a driven wheel, a traction rope, a driving assembly and an adjusting assembly. The driving wheel and the driven wheel are both rotatably mounted on the mounting frame, and the driven wheel can slide in the vertical direction of the mounting frame. The traction rope is hung on the driven wheel, the driving assembly is transmission-connected to the driving wheel, and the adjusting assembly is used to make the driven wheel approach or move away from the driving wheel. When the driven wheel approaches the driving wheel to clamp the traction rope, the driving assembly drives the driving wheel to rotate, and the traction rope is automatically pulled with the cooperation of the driven wheel.

[0007] By setting the above structure, when the patient is not tired, only the driven wheel can be used for manual traction. When the patient feels tired from manual traction, the driven wheel is brought close to the driving wheel and the traction rope is clamped by adjusting the component. The driving component drives the driving wheel to rotate, and the traction rope is automatically pulled with the cooperation of the driven wheel. While the patient is resting and relieving fatigue, he can also continue rehabilitation treatment, which effectively improves the patient's enthusiasm for rehabilitation treatment.

[0008] Furthermore, a mounting plate is provided on the mounting frame, and the adjusting assembly includes an adjusting block. A slide groove is provided on the mounting plate, and the adjusting block is slidably arranged in the slide groove. A coaxial adjusting column is rotatably installed on the driven wheel, and a guide slope is provided at one end of the adjusting block close to the adjusting column. When the adjusting block moves toward the adjusting column and the guide slope is connected to the adjusting column, the guide slope pushes the adjusting column to move upward, so that the driven wheel and the driving wheel clamp the traction rope.

[0009] By setting the above structure, the driven wheel can be controlled to approach or move away from the driving wheel only by moving the adjustment block, thereby realizing the switching between automatic traction and manual traction.

[0010] Furthermore, the mounting plate can be detachably mounted on the mounting frame, guide wheels are rotatably mounted on both ends of the mounting plate, and both ends of the traction rope are respectively hung on the two guide wheels.

[0011] By setting the above structure, when the patient needs to change the rehabilitation treatment position, the mounting plate can be directly removed from the mounting frame. After changing the position, the traction rope is hung on the guide wheels at both ends of the mounting plate for manual rehabilitation treatment.

When a pulling force is applied to the traction rope, the traction rope drives the guide wheel and the adjustment block to move toward the adjustment column, and the guide inclined surface pushes the adjustment column upward, so that the driven wheel and the driving wheel clamp the traction rope for automatic traction. When the pressure applied to the traction rope is released, the reset component resets the adjustment block, so that the driven wheel is away from the driving wheel, so that the traction rope can retreat, and there is no need to control the driving component to frequently turn.

[0014] Furthermore, the locking assembly includes a locking block, which is rotatably mounted on the adjusting block, and the locking block is provided with a first locking groove and a second locking groove, and the mounting plate is provided with a first locking column and a second locking column, and when the first locking groove of the locking block is locked with the first locking column, the driven wheel and the driving wheel are separated from each other, and when the second locking groove of the locking block is locked with the second locking column, the driven wheel and the driving wheel clamp the traction rope.

[0015] By setting the above structure, the adjusting block and the mounting plate can be quickly locked and released by moving the adjusting block and rotating the locking block, and the operation is simple and quick.

[0016] Furthermore, the reset assembly includes a support rod and a spring, the support rod is fixedly connected to the mounting frame, the spring is sleeved on the support rod, one end of the spring is fixedly connected to the mounting frame, and an avoidance hole is opened at the position of the adjustment block corresponding to the support rod.

[0018] Furthermore, a pressure sensor is arranged between the spring and the mounting frame, a control host is arranged on the mounting frame, and the pressure sensor and the driving component are both electrically connected to the control host.

[0019] By setting the above structure, the start and stop of the driving component can be controlled by the value change of the pressure sensor. When the two pressure sensors control the start, they can also control the rotation direction of the start respectively, effectively reducing the operation steps when the patient uses it.

[0020] Furthermore, the mounting frame includes a fixed bracket and a mounting bracket that are fixedly connected, the mounting bracket is provided with an axial hole, the driving wheel is provided with a rotating shaft, the rotating shaft is inserted into the axial hole, the mounting bracket is provided with a notch, and the adjusting column is slidably provided in the notch.

[0021] Through the above structure, the driving wheel and the driven wheel are rotatably connected to the mounting frame, and the driven wheel can slide along the vertical direction of the mounting frame.

[0022] Furthermore, the mounting bracket includes a first plate body and a second plate body, the tops of the first plate body and the second plate body are fixedly connected to the fixed bracket, the bottom of the first plate body is fixedly connected to the second plate body through a connecting plate, the notch is arranged on the first plate body, and the notch passes through the second plate body, and a through groove is opened on the first plate body, and the through groove is used for the traction rope to pass through.

[0031] 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.

[0032] like Figure 1-Figure 5 As shown, a scapulohumeral periarthritis rehabilitation device of the present invention comprises a mounting frame 1, a driving wheel 21, a driven wheel 22, a traction rope 23, a driving assembly 24 and an adjusting assembly 3. The driving wheel 21 and the driven wheel 22 are both rotatably mounted on the mounting frame 1, and the driven wheel 22 can slide in the vertical direction of the mounting frame 1. The traction rope 23 is hung on the driven wheel 22, and the driving assembly 24 is transmission-connected with the driving wheel 21. The adjusting assembly 3 is used to make the driven wheel 22 approach or move away from the driving wheel 21. When the driven wheel 22 approaches the driving wheel 21 to clamp the traction rope 23, the driving assembly 24 drives the driving wheel 21 to rotate, and the traction rope 23 is automatically pulled with the cooperation of the driven wheel 22. When the patient is not tired, only the driven wheel 22 can be used for manual traction. When the patient feels tired from manual traction, the driven wheel 22 is moved close to the driving wheel 21 and the traction rope 23 is clamped by adjusting the component 3. The driving component 24 drives the driving wheel 21 to rotate, and the traction rope 23 is automatically pulled with the cooperation of the driven wheel 22. While the patient is resting and relieving fatigue, he can also continue rehabilitation treatment, which effectively improves the patient's enthusiasm for rehabilitation treatment.

[0033] It should be noted that the driving assembly 24 of this embodiment is preferably a driving motor, and the output shaft of the driving motor is drivingly connected to the driving wheel 21.

[0034] In this embodiment, a mounting plate 4 is provided on the mounting frame 1, and the adjustment component 3 includes an adjustment block 31. A slide groove 41 is provided on the mounting plate 4. The adjustment block 31 is slidably arranged in the slide groove 41. A coaxial adjustment column 221 is rotatably installed on the driven wheel 22. A guide slope 32 is provided at one end of the adjustment block 31 close to the adjustment column 221. When the adjustment block 31 moves toward the direction close to the adjustment column 221, the guide slope 32 contacts the adjustment column 221, and the guide slope 32 pushes the adjustment column 221 to move up, so that the driven wheel 22 and the driving wheel 21 clamp the traction rope 23. When in use, only the adjustment block 31 needs to be moved to control the driven wheel 22 to approach or move away from the driving wheel 21, so as to realize the switching between automatic traction and manual traction. In some other embodiments, a cylinder can also be provided as the adjustment component 3, and the output shaft of the cylinder is fixedly connected to the adjustment column 221. The adjustment column 221 is driven to move up and down by the operation of the cylinder, so as to realize the switching between automatic traction and manual traction.

[0035] In this embodiment, the mounting plate 4 is detachably mounted on the mounting frame 1, and guide wheels 42 are rotatably mounted on both ends of the mounting plate 4, and both ends of the traction rope 23 are respectively hung on the two guide wheels 42. When the patient needs to change the rehabilitation treatment position, the mounting plate 4 can be directly removed from the mounting frame 1, and after changing the position, the traction rope 23 is hung on the guide wheels 42 at both ends of the mounting plate 4 for manual rehabilitation treatment.

[0036] In this embodiment, there are two groups of adjustment components 3, and the two groups of adjustment components 3 are respectively arranged corresponding to the two guide wheels 42. A connecting column 33 is arranged at one end of the adjustment block 31 away from the guide inclined surface 32, and the guide wheel 42 is rotatably mounted on the connecting column 33. A locking component 5 is arranged between the adjustment block 31 and the mounting plate 4, and the locking component 5 is used to lock the position of the adjustment block 31. A reset component 6 is arranged between the adjustment block 31 and the mounting frame 1, and the reset component 6 is used to reset the adjustment block 31. Now, take the right arm suffering from periarthritis of the shoulder as an example for explanation. During the use of (auxiliary traction), the right adjustment component 3 and the mounting plate 4 are first locked by the right locking component 5, so that the adjustment block 31 of the adjustment component 3 is away from the adjustment column 221, and the right guide wheel 42 is prevented from moving freely. Then, the left hand applies a pulling force to the left end of the traction rope 23, and the traction rope 23 drives the left guide wheel 42 and the adjustment block 31 to move toward the adjustment column 221, and compresses the reset component 6, and the guide slope 32 pushes the adjustment column 221 to move upward, so that the driven wheel 22 and the driving wheel 21 clamp the traction rope 23, and the traction is automatically performed under the drive of the working drive motor. After the left hand releases the left end of the traction rope 23, the reset component 6 resets the left adjustment block 31 and the guide wheel 42, so that the driven wheel 22 is away from the driving wheel 21, and the traction rope 23 is pulled back to the right side under the gravity of the right arm, and the rehabilitation treatment can be performed in this way. In this process, on the one hand, the drive motor only needs to control the driving wheel 21 to rotate clockwise, and there is no need to control the driving wheel 21 to rotate counterclockwise, and the traction rope 23 can also be retreated to the right side. The drive motor does not need to turn frequently, which effectively alleviates the heating of the drive motor and prolongs the service life of the motor. On the other hand, it is convenient for the patient to control the traction amplitude of the right arm so that the patient can adjust it according to his own situation. It should be noted that the pulling force applied by the left hand to the left end of the traction rope 23 is required to be much smaller than the pulling force applied by the left hand to the traction rope 23 during manual traction, so as to achieve a labor-saving effect.

[0037] In this embodiment, the locking assembly 5 is provided with two groups, and the two groups of locking assemblies 5 are respectively for two adjusting blocks 31. The locking assembly 5 includes a locking block 51, which is rotatably mounted on the adjusting block 31. The locking block 51 is provided with a first locking groove 511 and a second locking groove 512. The mounting plate 4 is provided with a first locking column 43 and a second locking column 44. When the first locking groove 511 of the locking block 51 is locked with the first locking column 43, the driven wheel 22 and the driving wheel 21 are separated, and manual traction can be performed at this time. When the second locking groove 512 of the locking block 51 is locked with the second locking column 44, the driven wheel 22 and the driving wheel 21 clamp the traction rope 23, and the driving motor is controlled to cycle forward and reverse, and automatic traction can be performed. When the locking block 51 is not locked, auxiliary traction in the above process can be performed. By moving the adjusting block 31 and rotating the locking block 51, the locking and disengagement between the adjusting block 31 and the mounting plate 4 can be quickly achieved, and the operation is simple and fast. In some other embodiments, the position of the adjustment block 31 can be locked directly by matching bolts and screw holes.

[0038] In this embodiment, the reset assembly 6 includes a support rod 61 and a spring 62. The support rod 61 is fixedly connected to the mounting frame 1. The spring 62 is sleeved on the support rod 61. One end of the spring 62 is fixedly connected to the mounting frame 1. The adjustment block 31 is provided with an escape hole 311 at a position corresponding to the support rod 61. The escape hole 311 is used to escape the support rod 61 so that the adjustment block 31 can smoothly squeeze the spring 62. When the pressure applied to the traction rope 23 is released, the spring 62 resets the adjustment block 31, so that the driven wheel 22 is away from the driving wheel 21, so that the traction rope 23 can retreat. In some other embodiments, the reset assembly 6 can also be set as a spring.

[0039] In this embodiment, a pressure sensor 7 is provided between the spring 62 and the mounting frame 1, and a control host is provided on the mounting frame 1, and the pressure sensor 7 and the drive assembly 24 are electrically connected to the control host. The start and stop of the drive assembly 24 are controlled by the value change of the pressure sensor 7. When the two pressure sensors 7 control the start, they can also control the rotation direction of the start respectively, which effectively reduces the operation steps when the patient uses it. When the value change of the pressure sensor 7 on the left exceeds the preset threshold, the control host controls the drive motor to work, driving the active wheel 21 to rotate clockwise. When the value change of the pressure sensor 7 on the right exceeds the preset threshold, the control host controls the drive motor to work, driving the active wheel 21 to rotate counterclockwise.

[0040] In some other embodiments, a gradient level can be set for the pressure value, and the speed of the motor can be controlled according to the size of the gradient level of the pressure value. For example, the greater the left hand pulling force, the faster the driving motor speed, and the faster the right hand rises; the smaller the left hand pulling force, the slower the driving motor speed, and the slower the right hand rises, so that the patient can save effort and control the speed of rehabilitation training according to his own situation.

[0041] In this embodiment, the mounting frame 1 includes a fixed bracket 11 and a mounting bracket 12 that are fixedly connected, an axial hole 13 is opened on the mounting bracket 12, a rotating shaft 211 is provided on the driving wheel 21, and the rotating shaft 211 is inserted into the axial hole 13, a notch 14 is provided on the mounting bracket 12, and an adjusting column 221 is slidably provided in the notch 14. The driving wheel 21 and the driven wheel 22 are rotatably connected to the mounting frame 1, and the driven wheel 22 can slide along the vertical direction of the mounting frame 1.

[0042] In this embodiment, the mounting bracket 12 includes a first plate 121 and a second plate 122. The tops of the first plate 121 and the second plate 122 are fixedly connected to the fixing bracket 11. The bottom of the first plate 121 is fixedly connected to the second plate 122 through a connecting plate. The notch 14 is provided on the first plate 121 and the notch 14 passes through the second plate 122. The first plate 121 is provided with a through slot 123 for the traction rope 23 to pass through. The notch 14 is provided on the first plate 121 and the notch 14 passes through the second plate 122. The two ends of the adjusting column 221 are respectively slidably clamped in the notch 14, so that the adjusting column 221 moves up and down more stably. In some other embodiments, only a single plate may be provided.

[0043] In this embodiment, a card slot 45 is provided on the mounting plate 4, and the card slot 45 is clamped on the mounting bracket 12. The mounting bracket 12 is rotatably connected with a locking plate 15, and a locking nut 16 is provided at the lower end of the locking plate 15. The locking nut 16 is used to lock the locking plate 15 with the mounting bracket 12, and the locking plate 15 is used to lock the mounting plate 4 on the mounting bracket 12. The detachable connection between the mounting plate 4 and the mounting bracket 1 is realized, and the operation is simple and convenient.

[0044] The scapulohumeral periarthritis rehabilitation device of the present invention, when used: During manual traction, the locking blocks 51 of the two locking assemblies 5 are locked with the corresponding first locking columns 43, and manual traction is then performed.

[0045] When the patient feels tired during manual traction and needs auxiliary traction, take the right arm with frozen shoulder as an example: First, the right side adjusting block 31 is locked with the mounting plate 4 by locking the right side locking block 51 with the corresponding first locking column 43. Then, the left hand applies tension to the left end of the traction rope 23, and the traction rope 23 drives the left guide wheel 42 and the adjustment block 31 to move closer to the adjustment column 221, and compresses the spring 62. The guide slope 32 pushes the adjustment column 221 upward, so that the driven wheel 22 and the driving wheel 21 clamp the traction rope 23.

[0046] When the value of the pressure sensor 7 on the left side changes beyond the preset threshold, the control host controls the driving motor to work, driving the driving wheel 21 to rotate clockwise. The driving wheel 21 cooperates with the driven wheel 22 to perform auxiliary traction.

[0047] When the left hand releases the left end of the traction rope 23, the spring 62 resets the left adjustment block 31 and the guide wheel 42, so that the driven wheel 22 moves away from the driving wheel 21, and the traction rope 23 is pulled back to the right under the gravity of the right arm, and rehabilitation treatment can be performed in this reciprocating manner.

[0048] When automatic traction is required, the locking block 51 of the locking assembly 5 on one side is locked with the corresponding second locking column 44, the driven wheel 22 and the driving wheel 21 clamp the traction rope 23, and the locking block 51 of the locking assembly 5 on the other side is locked with the corresponding first locking column 43, and the drive motor is controlled to cycle forward and reverse.
