[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figure 1 to Figure 2 As shown, an orthopedic activity device for preventing deep vein thrombosis of lower limbs according to an embodiment of the present invention comprises a base 1, the upper surface of which is fixedly connected with two lower limb exercise mechanisms 2, the lower limb exercise mechanisms 2 comprising a guide rod 21, a spring 1 22, a slide groove 23, a slider 24, a foot support plate 25, a leg support plate 26, a vertical plate 27, a spring 28, a strap 29, a leg support block 210, and a telescopic rod 211.

[0037] A spring 22 is arranged between the lower surface of the guide rod 21 and the upper surface of the base 1. Two springs 22 are symmetrically arranged. The springs 22 are arranged vertically. The upper end of the spring 22 is fixedly connected to the lower surface of the guide rod 21, and the lower end of the spring 22 is fixedly connected to the upper surface of the base 1. The spring 22 is a reinforced spring with a large elastic force and can withstand the weight of the user.

[0038] The guide rod 21 is arranged horizontally, and a slide groove 23 is provided on the upper surface of the guide rod 21, and both ends of the slide groove 23 are closed. A slider 24 is slidably installed in the slide groove 23, and the top of the slider 24 extends out of the slide groove 23 and is fixedly connected to the lower surface of the foot support plate 25, so that the foot support plate 25 can move horizontally left and right. The foot support plate 25 is arranged horizontally. The leg support plate 26 is arranged vertically, and one side of the foot support plate 25 is fixedly connected to the bottom of the leg support plate 26, and the foot support plate 25 and the leg support plate 26 are formed integrally. A vertical plate 27 is fixedly connected to one end of the guide rod 21, and the vertical plate 27 is arranged vertically, and the vertical plate 27 is formed integrally with the guide rod 21.

[0039] A spring 28 is arranged between the side of the leg support plate 26 away from the foot support plate 25 and the vertical plate 27. Two springs 28 are symmetrically arranged. The springs 28 are arranged horizontally. One end of the spring 28 is fixedly connected to the side of the vertical plate 27 close to the leg support plate 26, and the other end of the spring 28 is fixedly connected to the side of the leg support plate 26 close to the vertical plate 27. The spring 28 is a reinforced spring with a large elastic force, which can withstand the pressure applied by the user's legs.

[0040] Specifically, a strap 29 is provided on the leg support plate 26 , and the user's legs can be tied to the side of the leg support plate 26 away from the second spring 28 through the strap 29 .

[0041] Specifically, a leg support block 210 is provided on the side of the leg support plate 26 away from the spring 28. The leg support block 210 is made of silicone material. The user's legs are attached to the surface of the leg support block 210 and tied to the side of the leg support plate 26 away from the spring 28. When the user's legs apply pressure to the leg support plate 26 to compress the spring 28, the leg support block 210 can increase the comfort of the user's legs.

[0042] Specifically, a telescopic rod 211 is provided between the lower surface of the guide rod 21 and the upper surface of the base 1 , so that the guide rod 21 is more stable when moving up and down.

[0043] The working principle and use process of the embodiment of the present invention are as follows: first, the user places the foot on the foot support plate 25, and then the user uses the strap 29 to tie the leg to one side of the leg support plate 26 and the surface of the leg support block 210; when the user's foot exerts force downward, the spring 22 is compressed, and the user moves the guide rod 21 downward; when the user stops moving, the user's foot is reset under the elastic restoring force of the spring 22, and the user exercises in the above manner. Under the above exercise, the user's foot continuously exerts force downward, thereby continuously exercising the user's foot; when the user's leg exerts force in the direction close to the vertical plate 27 At this time, spring 28 is compressed, and the user carries the leg support plate 26 to move in the direction close to the vertical plate 27. When the user stops moving, the user's legs are reset under the elastic restoring force of spring 28, and exercise is performed in the above manner. Under the above-mentioned exercise, the user's legs continuously exert force in the direction close to the vertical plate 27, thereby continuously exercising the user's legs. In the above-mentioned manner, during the exercise process, the user's lower limbs continuously change positions, and the user's lower limbs are not only fully exercised, but also the user's physical fitness is enhanced. This method can effectively exercise the lower limbs and effectively prevent the formation of deep vein thrombosis in the lower limbs.

[0044] like Figure 3 to Figure 4 As shown, two support columns 3 are symmetrically arranged on the upper surface of the base 1, and the support columns 3 are arranged vertically. The bottom of the support columns 3 is fixedly connected to the upper surface of the base 1, and a protective mechanism 4 is connected to the support columns 3. The protective mechanism 4 includes a wearable component 41, and the wearable component 41 includes a fixed ring 411, an annular groove 412, an inner ring plate 413, a protective airbag 414, a protective plate 415, and an elastic plate 416. The fixed ring 411 is connected to the support column 3, and an annular groove 412 is provided on the inner side of the circumference of the fixed ring 411, and the inner ring plate 413 is rotatably installed in the annular groove 412. The outer side of the protective airbag 414 is fixedly connected with a protective plate 415, and the protective plate 415 is provided with multiple and evenly distributed on the outer side of the protective airbag 414. A plurality of elastic plates 416 are arranged between the protective plate 415 and the inner side of the inner ring plate 413, and when the protective plate 415 is close to the fixed ring 411, the elastic plate 416 is compressed.

[0045] Specifically, existing devices for preventing deep vein thrombosis of the lower limbs promote blood circulation in the lower limbs by continuously exercising the user's lower limbs, thereby effectively preventing the occurrence of deep vein thrombosis of the lower limbs. However, when users are exercising their lower limbs, they may unknowingly increase the intensity of their lower limb activities. For the elderly or users who have just completed orthopedic surgery, they are often prone to falling without protection.

[0046] Therefore, the present invention solves this problem by setting up a certain structure. First, the user enters the protective airbag 414. Since the protective airbag 414 is annular, it can wrap the user's waist. Then, the protective airbag 414 is inflated so that the inner wall of the protective airbag 414 is close to the user's waist. The protective airbag 414 is convenient for adapting to people of different fat and thin sizes. The protective airbag 414 can also cooperate with the elastic plate 416 to provide cushioning for the user's movement to avoid the user's lower limbs from being subjected to greater impact and causing discomfort during exercise. The protective airbag 414 wraps the user's waist and allows the user to freely choose the intensity of the lower limb activity. It is safer and solves the problem that the user will unknowingly increase the intensity of the lower limb activity during lower limb exercise, which may cause the elderly or users who have just finished orthopedic surgery to fall without protection.

[0047] Embodiment 2

[0048] like Figures 5 to 9 As shown, compared with the first embodiment, the present embodiment is different from the first embodiment in that: the protection mechanism 4 further includes a moving member 42 , and two moving members 42 are symmetrically arranged and respectively located on both sides of the fixed ring 411 .
