Abstract
Description
Technical Field

[0002] The knee joint is composed of the lower end of the femur, the upper end of the tibia and the patella. It is the largest and most complex joint in the human body. It bears almost all of the body weight and also undertakes various leg movement tasks. Knee osteoarthritis is the most common musculoskeletal disease and the main cause of disability in the middle-aged and elderly. It can cause knee pain, joint swelling, and even joint stiffness and deformation, leading to functional impairment.
[0003] The knee joint massager can massage the knee joint through built-in massage components, heating components and other functional components, which can relieve knee joint discomfort and assist in the recovery of knee joint function. Existing knee joint massagers are roughly divided into two types: wearable massagers with massage components set in the elastic fabric body and wearable massagers realized by the casing and fixing parts such as straps. The wearable massager adapts to the size and curvature of the knee joints of users of different body shapes through the elasticity provided by the elastic fabric, but the low structural strength of the elastic fabric affects the massage effect of the massage component. The casing of the wearable massager has high structural strength, the massage component is firmly installed, and the massage effect is good, but the wearing cavity in the casing cannot be adjusted, and it cannot match the knee joints of different users, which will also affect the use effect.

Correspondingly, see Figure 6 As shown, the connecting buckle 15 includes a buckle plate 151 and two buckle arms 152 protruding from one side of the buckle plate 151 and distributed radially at intervals. Each buckle arm 152 forms a radially outwardly protruding buckle 153 at the end away from the buckle plate 151. The buckle plate 151 also has two limiting grooves 154 on both sides of the radial direction staggered from the two buckle arms 152.
[0045] Recombination Figure 7 As shown, when the lower wrapping shell 12 and the knee wrapping shell 13 are rotatably connected by the left and right connecting plates 14 and the corresponding two connecting buckles 15, the corresponding end of the knee wrapping shell 13 can be firstly overlapped in the lower wrapping shell 12, so that the fourth connecting hole 136 on the knee wrapping shell 13 is aligned with the second connecting hole 124 on the lower wrapping shell 12; then, a pin 142 of the connecting plate 14 can be inserted from the outside of the lower wrapping shell 12 into the second connecting hole 124 and then inserted into the fourth connecting hole 136 of the knee wrapping shell 13 until the limiting step 143 on the periphery of the pin 142 abuts against the second step 125 at the outer end of the second connecting hole 124; then, the connecting buckle 15 is inserted into the fourth connecting hole 136 from the inside of the knee wrapping shell 13, so that the two buckle arms on the connecting buckle 15 152 is elastically deformed by being squeezed and inserted into the insertion hole 144 of the pin 142 which has been placed in the fourth connecting hole 136. When the plate body 151 of the connecting buckle 15 abuts against the fourth step 137 at the inner end of the fourth connecting hole 136, the buckles 153 at the ends of the two buckle arms 152 of the connecting buckle 15 are just snapped into the two corresponding slots 146 opened on the outer periphery of the pin 142 under the action of elastic force. At the same time, the two plug blocks 145 at the ends of the pin 142 are also inserted into the two corresponding limit grooves 154 opened on the buckle plate 151 of the connecting buckle 151, so as to realize the fixed connection between the connecting buckle 15 and the connecting plate 14. The lower wrapping shell 12 and the knee wrapping shell 13 are respectively clamped between the connecting plate 14 and the connecting buckle 15 through the second connecting hole 124 and the fourth connecting hole 136 and can realize relative rotation around the pin 142.
[0046] Similarly, the corresponding end of the knee wrap shell 13 is overlapped in the upper wrap shell 11, so that the third connecting hole 134 on the knee wrap shell 13 is aligned with the first connecting hole 114 on the upper wrap shell 11, and then the other pin 142 of the connecting plate 14 is inserted from the outside of the upper wrap shell 11 into the first connecting hole 114 and then into the third connecting hole 134 of the knee wrap shell 13 until the limiting step 143 on the periphery of the pin 142 abuts against the first step 115 at the outer end of the first connecting hole 114; then, a connecting buckle 15 is inserted into the third connecting hole 134 from the inside of the knee wrap shell 13, so that the two buckle arms 152 on the connecting buckle 15 are squeezed and elastically deformed and inserted into the third connecting hole 13 4, when the plate body 151 of the connecting buckle 15 abuts against the third step 135 at the inner end of the third connecting hole 134, the buckles 153 at the ends of the two buckle arms 152 of the connecting buckle 15 are just snapped into the two corresponding slots 146 on the outer periphery of the plug pin 142 under the action of elastic force. At the same time, the two plug blocks 145 at the ends of the plug pin 142 are also inserted into the two corresponding limiting slots 154 on the buckle plate 151 of the connecting buckle 151, so as to realize the fixed connection between the connecting buckle 15 and the connecting plate 14. The upper wrapping shell 11 and the knee wrapping shell 13 are respectively clamped between the connecting plate 14 and the connecting buckle 15 through the first connecting hole 114 and the third connecting hole 134 and can realize relative rotation around the plug pin 142.
[0047] According to different embodiments of the present application, the number and distribution of the buckle arms 152 and the limiting grooves 154 on the above-mentioned connecting buckle 15 are not limited to the illustrated embodiment. Similarly, the number and distribution of the slots 146 and the plug blocks 145 on the pin 142 of the connecting plate 14 are also not limited to the illustrated embodiment. As long as they correspond to each other and are staggered to form a buckle limiting fixation of the connecting buckle 15 and the connecting plate 14, it will be sufficient.
[0048] According to the above embodiment of the present application, the shell 10 of the knee joint massager 100 is composed of an upper wrapping shell 11 and a lower wrapping shell 12 which are rotatably connected to the two ends of the knee wrapping shell 13 to form a three-section design.
