Description

Technical Field

[0001] The utility model relates to the technical field of training equipment, in particular to orthopedic foot and ankle strength training equipment. Background Art

[0002] The feet are the second heart of the human body, and the ankles are an important gateway for blood flow to the left and right feet. The smoothness of blood circulation in the lower body has a great impact on the blood circulation of the whole body. The ankles are an important part for blood flow to the left and right feet, so keeping the ankles soft and flexible through gymnastics or massage is beneficial to human health. If the ankles are soft and elastic, the venous blood returning to the heart can pass smoothly through the ankles. If the ankles are old and stiff, the venous blood returning to the heart will stagnate near the ankles like a traffic jam, which will increase the burden on the heart and increase the risk of high blood pressure in the long run.

[0003] Currently, when treating patients with foot and ankle injuries, the patient's ankle needs to be fixed to speed up the patient's recovery. However, long-term fixation will cause the ankle to age and become stiff. Therefore, the patient needs to undergo foot and ankle strength training to restore the elasticity of the patient's ankle. However, manual massage by the patient himself cannot achieve the desired effect. Therefore, an orthopedic foot and ankle strength training device is needed.

[0004] Chinese patent document CN211215234U discloses a foot and ankle muscle training device, including a base, a fixed block is installed on the inner side of the base, and the fixed block is connected to a foot pad through a connecting rod, a spring is connected to the connecting rod, a pad is provided at the front end of the base, and an elastic sleeve is installed on the upper side of the pad, the foot pad is connected to the base through a support rod, a massage ball is provided in the middle part of the foot pad, a sleeve rod is connected to the rear end of the base, and an insertion rod is inserted at the upper end of the sleeve rod, an armrest is connected to the upper end of the insertion rod, and a cushion is installed on the insertion rod. The above utility model trains the foot and ankle through three training methods, and the three training methods have different intensities, so that the trainee can choose the appropriate training method according to his or her own physical fitness, thereby improving the training efficiency, and also greatly improving the scope of application. However, the above patent document still has the following defects during use:

[0005] The above patent document is not convenient for multi-angle training of the ankle during use, and the trained ankle area is limited, and the limited training area may affect the training effect. Utility Model Content

DETAILED DESCRIPTION

[0025] 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 described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, an orthopedic foot and ankle strength training device includes a base 3, a support ring 31 is fixedly connected to the outer side of the upper end of the base 3, two connection blocks 2 are fixedly connected to the left and right sides of the outer surface of the base 3, and an armrest assembly 1 is fixedly connected to the upper ends of the two connection blocks 2 on the same side. A semicircular seat 6 is provided inside the support ring 31, and four adjustment assemblies 4 are provided in a circular array at the lower end of the semicircular seat 6. A support column 5 is fixedly connected to the circular array at the lower end of the base 3, and two foot pads 7 are fixedly connected to the upper end of the semicircular seat 6 symmetrically. Velcro 71 is fixedly connected to the front and back of the left and right ends of the two foot pads 7.

[0027] During the specific implementation of the utility model, the device is first moved to the training ground, and then the regulating component 4 can be used to limit the movement direction according to the training intensity of the user, and the front and rear ankle training, the left and right ankle training, and the all-round ankle training can be performed. At the same time, before training, the training intensity can also be adjusted according to the training intensity of the user to better meet the user's usage conditions. Then, according to the specific height of the user, the height of the armrest component 1 is adjusted to a gripping height suitable for the user, and the armrest component 1 is supported by the base 3 and the connecting block 2. Then, the user stands on the foot pad 7 on the upper part of the semicircular seat 6 holding the armrest component 1, and fixes the foot with Velcro 71. After completion, the semicircular seat 6 can be used for training.

[0028] The Velcro 71 mentioned above is composed of two mutually bonded male and female Velcros in the prior art. The two Velcros on the same side can be glued together to fix the sole of the foot. The two Velcros can be separated by tearing the upper Velcro to release the fixation of the sole of the foot.

[0029] The semicircular seat 6 is composed of a receiving plate and a semicircular balancing ball. When a user stands on the receiving plate, the user can tilt the seat in any direction.

[0030] The above-mentioned regulating components 4 can be installed and increased in number as needed, and training can be performed at more angles after the increase.

[0031] Specifically, in order to adjust the training angle, refer to Figure 2 and Figure 3 The handrail assembly 1 includes a sleeve rod 13, and the inner surfaces of the two sleeve rods 13 on the same side are slidably connected with a slide rod 11, and a buckle 12 is provided at the connection between the slide rod 11 and the sleeve rod 13;

[0032] For further information, see Figure 3The regulating component 4 includes a fixed block 43, the upper end of the fixed block 43 is fixedly connected to the force regulating component 42, the upper part of the force regulating component 42 is fixedly connected to the pad 41, the lower part of the pad 41 is provided with a threaded rod 44, and the upper end of the threaded rod 44 is fixedly connected to an elastic ball;

[0033] For further information, see Figure 3 , the fixing block 43 is fixedly connected to the base 3, and the four threaded rods 44 all penetrate the base 3 and extend to the lower part of the lower end of the pad 41 and are threadedly connected to the base 3;

[0034] The buckle 12 mentioned above is a real elastic buckle, which can fix the position between the slide rod 11 and the sleeve rod 13, and can also release the fixation so that the slide rod 11 slides inside the sleeve rod 13.

[0035] The initial positions of the upper parts of the plurality of threaded rods 44 are all far from the pad 41.

[0036] It can be seen from this that first, the fixation of the buckle 12 is released, and then the slide bar 11 is slid upward or downward according to the specific height of the user, until the height of the upper part of the slide bar 11 is suitable for the user's supporting height. Then, according to the user's training intensity, the regulating component 4 can be used to limit the movement direction, and front and rear ankle training, left and right ankle training, or all-round ankle training can be performed. When limiting, the threaded rod 44 can be rotated so that the threaded rod 44 gradually approaches the lower end of the pad 41 until it is tightly attached, so that the pad 41 on the same side will not be squeezed downward by the semicircular seat 6 when stepping on. At the same time, the elastic ball at the upper end of the threaded rod 44 can be smoothly rotated at the lower part of the semicircular seat 6 and the upper end of the base 3, so that the movement direction of the left and right sides of the semicircular seat 6 can be limited, and the movement direction of the front and rear sides can also be limited. It can be adjusted according to the specific training direction to further improve the practicality of the device.

[0037] Specifically, in order to adjust the intensity of training, refer to Figure 4 and Figure 5 The force adjustment component 42 includes a sleeve 422, the inner surface of the sleeve 422 is slidably connected to an extrusion rod 421, the lower end of the extrusion rod 421 and the bottom wall of the inner surface of the sleeve 422 are fixedly connected with a spring 424, the outer surface of the sleeve 422 is centrally symmetrically provided with two slide grooves, the inner surfaces of the two slide grooves are slidably connected to a limit assembly 423, the upper end of the extrusion rod 421 is fixedly connected to a ball, and the ball is movably connected to the pad 41 on the same side;

[0038] For further information, see Figure 4 , the sleeve 422 is fixedly connected to the fixing block 43 on the same side;

[0039] For further information, see Figure 5The limit assembly 423 includes a slip ring 4231 and two receiving blocks 4233. One side of the upper end of the slip ring 4231 is threadedly connected with a threaded rod 4232 that penetrates the slip ring 4231 and extends to the upper end of the receiving block 4233 on the same side and is rotatably connected to the receiving block 4233. The other side of the upper end of the slip ring 4231 is slidably connected with a limit rod 4234 that penetrates the slip ring 4231 and extends to the upper end of the receiving block 4233 on the same side and is fixedly connected to the receiving block 4233.

[0040] For further information, see Figure 4 The inner surface of the slip ring 4231 is slidably connected to the outer surface of the extrusion rod 421, the slip ring 4231 is slidably connected to the sleeve 422, and the slip ring 4231 is slidably connected to the slide groove;

[0041] The spring 424 is pressed against the backing plate 41 on the same side, and the backing plate 41 is pressed against the backing plate 41 on the same side, so that the training intensity is increased. If the training intensity is too large, the spring 424 can reduce the upward spring force of the backing plate 421. If the training intensity needs to be increased, the threaded rod 4232 is first rotated to drive the sliding ring 4231 to slide downward on the inner surface of the sleeve 422, and the sliding ring 4231 can be driven to slide downward on the inner surface of the sleeve 422. During the movement, the sliding ring 4231 slides on the outer surface of the limiting rod 4234 to maintain the stability of the sliding ring 4231 moving downward to avoid damage to the components. During the descending process of the backing plate 421, the spring 424 will be squeezed to move downward together. When the backing plate 41 moves downward, it will drive the backing plate 41 to move downward together, away from the moving distance of the semicircular seat 6, and the position of the backing plate 421 will be limited by the spring 424.

[0042] At this time, the spring 424 is squeezed and the elastic force generated becomes larger. If the squeezing rod 421 is pressed, a larger pedaling force is required, and the semicircular seat 6 is stepped on to squeeze the pad 41, which can be smoothly tilted downward with the cooperation of the ball. As the squeezing rod 421 squeezes the spring 424, the pedaling force needs to become larger, which can achieve the purpose of increasing the strength of ankle training. After the pedaling is completed, slowly flatten the sole of the foot, and then continue to pedal in the other direction, and repeat the training in this way.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
