Technical Field
[0001] This invention relates to the field of protective technology, and more particularly to a protective device for rheumatism. Background Technology
[0002] Rheumatism is a chronic inflammatory disease that commonly affects the elderly. When exposed to damp and cold weather, it can cause pain in the joints and muscles, especially the knees. To alleviate the pain, protective measures are necessary.
[0003] There are few and inconvenient ways to care for rheumatism patients. They either use knee pads to protect their knee joints or massage chairs to massage their legs. However, knee pads only provide support and warmth and cannot provide massage. Massage chairs can only be used when the patient is not walking, as they cannot accelerate blood circulation in the knee joint through massage when walking.
[0004] Therefore, there is an urgent need to invent a rheumatism prevention device that automatically massages the body while walking. Summary of the Invention
[0005] To overcome the shortcomings of knee pads that only provide support and warmth but cannot provide massage, and massage chairs that can only be used when the patient is not walking and cannot accelerate blood circulation in the knee joint through massage while walking, this invention provides a rheumatism protection device that automatically massages while walking.
[0006] A protective device for rheumatism includes a locking block, the locking block being wrapped with a strap, the strap being fixedly connected to a first sleeve, the first sleeve being fixedly connected to a connecting sleeve, the connecting sleeve being fixedly connected to a second sleeve, the first sleeve, the second sleeve and the connecting sleeve being made of a tough material, the connecting sleeve being fixedly connected to a plaster plate, and the first sleeve being provided with a massage component for massaging the leg at the knee joint.

The rotating rollers press the first and second sleeves to massage the patient's legs. A first spring is fixedly connected between the slider and an adjacent fixing frame. A lever is fixedly connected to the slider near the first telescopic assembly, and the lever engages with the first telescopic assembly.
[0008] As a preferred embodiment of the present invention, the rotating rod and the first telescopic component together form a triangle to enhance stability.
[0009] As a preferred embodiment of the present invention, it further includes a fixing ring fixedly connected to the first sleeve. The first sleeve is fixedly connected to a circumferentially distributed elastic band, which is made of a soft material. The elastic band is fixedly connected to a guide plate. The first sleeve is fixedly connected to a circumferentially distributed second telescopic assembly. A pushing ring is fixedly connected between the telescopic ends of the circumferentially distributed second telescopic assemblies. The pushing ring is fixedly connected to a circumferentially distributed pushing ball, which engages with the adjacent guide plate. The pushing ring is fixedly connected to a third telescopic assembly, which is fixedly connected to a rack. A gear is fixedly connected to a second rotating shaft near the first sleeve, and the gear meshes with the rack.
[0010] As a preferred embodiment of the present invention, the vertical distance between the side of the guide plate closer to the fixing ring and the elastic band is less than the vertical distance between the side of the guide plate farther from the fixing ring and the elastic band.
[0011] As a preferred embodiment of the present invention, it further includes a pressure ball, which is fixedly connected to the fixing frame near the push ring. The push ring is fixedly connected to an air cylinder, and the pressure ball is connected to an air pipe. The air pipe is slidably connected to the air cylinder, and a second spring is fixedly connected between the air pipe and the air cylinder.
[0012] As a preferred embodiment of the present invention, it further includes a first fixing plate, which is fixedly connected to the fixing ring. The first fixing plate is slidably connected to a wedge-shaped frame, which cooperates with the pushing ring. A third spring is fixedly connected between the wedge-shaped frame and the first fixing plate.
[0013] As a preferred embodiment of the present invention, the pushing ring has a limiting hole that cooperates with the wedge-shaped frame.
[0014] As a preferred embodiment of the present invention, it further includes a second fixing plate, which is fixedly connected to the connecting cylinder.

[0015] As a preferred embodiment of the present invention, it further includes a driving rod, which is fixedly connected to a second rotating shaft near the second sleeve. A fixing ring is fixedly connected to the second sleeve, and symmetrically distributed fourth telescopic components are fixedly connected to the fixing ring. A lifting frame is fixedly connected between the symmetrically distributed fourth telescopic components. The lifting frame is in a pressing fit with the driving rod. A circumferentially distributed striking plate is rotatably connected to the fixing ring. A first torsion spring is fixedly connected between the striking plate and the fixing ring. A one-way plate is rotatably connected to the striking plate. The one-way plate is in a pressing fit with the lifting frame. A second torsion spring is fixedly connected between the one-way plate and the adjacent striking plate.
[0016] Beneficial effects: 1. When the patient walks, the continuous bending and straightening of the knees drives the rollers to roll back and forth, thereby massaging the leg joints at the knees and relieving rheumatic pain.
[0017] 2. When the patient walks, the continuous bending and straightening of the knees can intermittently and slightly relax the tightness of the first sleeve on the legs, preventing poor blood circulation when the patient's knees are straight during walking.
[0018] 3. When the patient sits down to rest after wearing this device, the pressure ball is squeezed by the chair or stool, causing the push ring to move the push ball closer to the fixed ring, so that the patient can relax the tightness of the first sleeve on the legs when resting and sitting down.
[0019] 4. After the patient sits down to rest, the push ring can be manually pushed so that the wedge frame is engaged in the limiting hole, thereby limiting the push ring. This allows the first sleeve to be kept slightly loose during the resting process, and also increases the loosening force.
[0020] 5. After the patient puts on this device, the smoothing frame rotates to apply pressure evenly to the plaster on the plaster plate, so that the plaster is evenly squeezed to the knee and the effect of the application is improved.
[0021] 6. When the patient walks with their knees straight, the lower second pivot drives the lever to rotate, causing the tapping plate to rotate inward and tap the second sleeve, achieving the effect of tapping and massaging the lower joint of the knee while walking, further relieving rheumatic pain.

Detailed Implementation
[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0035] Example 1: A protective device for rheumatism, such as Figures 1-3 As shown, it includes a locking block 1, a strap 101 wrapped around the locking block 1, a first sleeve 102 fixedly connected to the strap 101, a connecting sleeve 103 fixedly connected to the right side of the first sleeve 102, and a second sleeve 104 fixedly connected to the connecting sleeve 103. The first sleeve 102, the second sleeve 104 and the connecting sleeve 103 are all made of a tough material. A plaster plate 105 for applying rheumatism plaster is fixedly connected to the right side of the connecting sleeve 103. The first sleeve 102 is provided with a massage component. When the rheumatism patient walks, the massage component is driven to massage the leg at the knee joint back and forth to relieve rheumatic pain.
[0036] like Figure 4 As shown, the massage assembly includes a first rotating shaft 2, which is rotatably connected to a connecting cylinder 103. Vertically distributed rotating rods 201 are fixedly connected to the first rotating shaft 2. Fixing blocks 203 are fixedly connected to the front sides of both the first sleeve 102 and the second sleeve 104. The fixing blocks 203 are fixedly connected to adjacent rotating rods 201. A second rotating shaft 202 is rotatably connected to the front side of the fixing blocks 203. A first telescopic component 204 is fixedly connected between the two second rotating shafts 202. The two rotating rods 201 and the first telescopic component 204 together form a triangle to enhance stability. Fixing frames 208 are fixedly connected to both the first sleeve 102 and the second sleeve 104. The fixing frame 208 is U-shaped, with the ends of the upper and lower fixing frames 208 in contact with each other. The fixing frame 208 is slidably connected to symmetrically distributed sliders 205. Adjacent sliders 205 are rotatably connected to rollers 206. The rollers 206 are in contact with the first sleeve 102 and the second sleeve 104 respectively. The rollers 206 rotate to roll and press the first sleeve 102 and the second sleeve 104 for massaging the patient's legs. A first spring 207 is fixed between the slider 205 and the adjacent fixing frame 208. A lever 209 is fixed to the front slider 205. The lever 209 is pressed and engaged with the first telescopic component 204.
[0037] Before wearing this device, rheumatism patients first apply a plaster for relieving rheumatic pain to the plaster tray 105. Then, the leg is passed through the strap 101, the first sleeve 102, the connecting sleeve 103, and the second sleeve 104 in sequence, with the plaster positioned at the knee joint. The leg strap 101 is then tightened around the thigh. After wearing the device, the patient can walk freely. During walking, the knee will flex and straighten, causing the first sleeve 102 and the connecting sleeve 103 to flex and straighten. The rotating rod 201 drives the upper second rotating shaft 202 to rotate back and forth around the first rotating shaft 2. The second rotating shaft 202 drives the first telescopic component 204 to rotate back and forth around the lower second rotating shaft 202. Under the squeezing action of the first telescopic component 204 and the restoring action of the first spring 207, the lever 209 drives the roller 206 to roll back and forth through the slider 205, thereby performing roller massage on the legs at the first sleeve 102 and the second sleeve 104. Before removing this device, loosen the strap 101.
[0038] In summary, when patients walk, the continuous bending and straightening movements of their knees drive the roller 206 to roll back and forth, thereby massaging the leg joints at the knee and relieving rheumatic pain.
[0039] Example 2: Based on Example 1, as follows Figures 5-6 As shown, it also includes a fixing ring 3, which is fixed to the first sleeve 102. The first sleeve 102 is fixed with a circumferentially distributed elastic band 302, which is made of soft material. The elastic band 302 is fixed with a guide plate 301. The vertical distance between the left side of the guide plate 301 and the elastic band 302 is less than the vertical distance between the right side of the guide plate 301 and the elastic band 302. The first sleeve 102 is fixed with a circumferentially distributed second telescopic component 304. A push ring 303 is fixed between the telescopic ends of the circumferentially distributed second telescopic component 304. A circumferentially distributed push ball 305 is fixed to the right side of the push ring 303. The push ball 305 is in a limiting engagement with the adjacent guide plate 301. A third telescopic component 306 is fixed to the front of the push ring 303. A rack 307 is fixed to the telescopic end of the third telescopic component 306. A gear 308 is fixed to the upper second rotating shaft 202. The gear 308 meshes with the rack 307.
[0040] When the patient walks with their knees upright, the fixing ring 3, guide plate 301, elastic band 302, push ring 303, second telescopic component 304, push ball 305, third telescopic component 306, rack 307, and gear 308 rotate upright along with the first sleeve 102 and connecting cylinder 103. Due to the change in the stroke of gear 308, gear 308 drives rack 307 to move, thereby squeezing third telescopic component 306. When third telescopic component 306 is compressed to its limit, rack 307 drives push ring 303 through third telescopic component 306 to squeeze second telescopic component 304. Push ring 303 simultaneously drives push ball 305 to move closer to fixing ring 3. Push ball 305 pulls guide plate 301 outward. Guide plate 301 intermittently and slightly loosens first sleeve 102 outward through elastic band 302.
[0041] When the patient bends their knee while walking, the gear 308 rotates clockwise relative to the rack 307, thereby causing the rack 307 to move in the opposite direction. The third telescopic component 306 resets, and the rack 307 pulls the push ring 303 to move in the opposite direction through the third telescopic component 306. The second telescopic component 304 resets, and the push ring 303 is no longer tightened by the guide plate 301. The first sleeve 102 relaxes and returns to its original position.
[0042] In summary, when patients walk, the continuous bending and straightening movements of their knees can intermittently and slightly relax the binding of the first sleeve 102 on the legs, preventing poor blood circulation when the knees are straight during walking.
[0043] like Figure 7 As shown, it also includes a pressure ball 4, which is fixed to the upper frame 208. When the patient sits down to rest, the chair or stool squeezes the pressure ball 4, and the right side of the push ring 303 is fixed to the air cylinder 402. The pressure ball 4 is connected to the trachea 401, and the trachea 401 is slidably connected to the air cylinder 402. A second spring 403 is fixed between the trachea 401 and the air cylinder 402.
[0044] When the patient sits down to rest after wearing this device, the pressure ball 4 is squeezed by the chair or stool, which forces gas through the air tube 401 into the air cylinder 402. The air pressure pushes the air cylinder 402 to move, which in turn pushes the push ring 303 to move. This causes the push ring 303 to move the push ball 305 to the side closer to the fixed ring 3. In this way, the first sleeve 102 can be relaxed on the legs when the patient is resting and sitting down.
[0045] like Figure 8 As shown, it also includes a first fixing plate 5, which is fixed to the top of the fixing ring 3. A wedge-shaped frame 501 is slidably connected to the right side of the first fixing plate 5. The pushing ring 303 has a limiting hole that cooperates with the wedge-shaped frame 501. The wedge-shaped frame 501 cooperates with the pushing ring 303. A third spring 502 is fixed between the wedge-shaped frame 501 and the first fixing plate 5.
[0046] During the above process, when the pushing ring 303 moves towards the side closer to the fixed ring 3, it will not contact the wedge frame 501 due to the small driving force. After the patient sits down to rest, the pushing ring 303 can be manually pushed, so that the pushing ring 303 squeezes the wedge frame 501 and the third spring 502 is compressed. When the wedge frame 501 corresponds to the limiting hole, the third spring 502 resets and drives the wedge frame 501 to be inserted into the limiting hole, thereby limiting the pushing ring 303. In this way, the first sleeve 102 can be kept slightly loose during the resting process, and the loosening force can be increased.
[0047] like Figure 9 As shown, it also includes a second fixing plate 6, which is fixed to the connecting cylinder 103. A motor 601 is fixed to the second fixing plate 6, and a smoothing frame 602 is fixed to the output shaft of the motor 601. The smoothing frame 602 is used to spread the plaster on the plaster tray 105 evenly.
[0048] After the patient puts on the device, they can start the motor 601. The output shaft of the motor 601 drives the smoothing frame 602 to rotate, thereby applying a certain amount of pressure to the plaster on the plaster plate 105, so that the plaster is evenly squeezed to the knee, improving the efficacy of the application. When removing the device, the motor 601 is turned off.
[0049] like Figures 10-11 As shown, it also includes a driving rod 7, which is fixed to the second rotating shaft 202 on the lower side. A fixing ring 703 is fixed to the lower part of the second sleeve 104. The fixing ring 703 is fixed to a fourth telescopic component 702 that is symmetrically distributed front and rear. A lifting frame 701 is fixed between the telescopic ends of the fourth telescopic component 702 that is symmetrically distributed front and rear. The lifting frame 701 is in a pressing fit with the driving rod 7. The driving rod 7 rotates downward to press the lifting frame 701 to move downward. The fixing ring 703 is rotatably connected to a circumferentially distributed tapping plate 704. The tapping plate 704 rotates inward to tap and massage the joint below the knee. A first torsion spring 705 is fixed between the tapping plate 704 and the fixing ring 703. The tapping plate 704 is rotatably connected to a one-way plate 706. The one-way plate 706 is in a pressing fit with the lifting frame 701. A second torsion spring 707 is fixed between the one-way plate 706 and the adjacent tapping plate 704. The second torsion spring 707 restricts the one-way plate 706 to rotate only upward.
[0050] When the patient's knees are straight during walking, the lower second pivot 202 drives the drive rod 7 to rotate, causing the drive rod 7 to press the lifting frame 701 downward. The fourth telescopic component 702 is compressed, and the lifting frame 701 drives the striking plate 704 to rotate outward through the one-way plate 706. The first torsion spring 705 deforms. When the lifting frame 701 moves downward and disengages from the one-way plate 706, the first torsion spring 705 resets, causing the striking plate 704 to rotate inward and strike the second sleeve 104.
[0051] When the second rotating shaft 202 at the bottom drives the driving rod 7 to rotate in the opposite direction and disengage from the lifting frame 701, the fourth telescopic component 702 resets and drives the lifting frame 701 to move upward. The lifting frame 701 presses against the one-way plate 706 and rotates upward. The second torsion spring 707 deforms. When the lifting frame 701 moves upward past the one-way plate 706, the second torsion spring 707 resets and drives the one-way plate 706 to rotate downward and reset.
[0052] In summary, when the patient's knee is upright while walking, the lower second pivot 202 drives the lever 7 to rotate, causing the striking plate 704 to rotate inward and strike the second sleeve 104, achieving the effect of tapping and massaging the lower joint of the knee while walking, further relieving rheumatic pain.
[0053] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
