Description
Technical Field
[0001] This utility model belongs to the field of rehabilitation equipment technology, and in particular relates to a leg training strap that is easy to wear. Background Technology
[0002] With societal development, the number of patients with limb movement disorders due to population aging and various diseases and accidents is increasing. Patients with functional impairments or disabilities caused by accidents, congenital defects, diseases, etc., urgently need effective medical rehabilitation. Numerous studies have found that rehabilitation training can promote the plasticity and functional reorganization of the central nervous system, maximizing the recovery or compensation of the patient's original limb functions, enabling patients to achieve maximum self-care and improve their quality of life. In reality, many devices are available for lower limb rehabilitation training, but most are complex in structure, expensive to manufacture, and inconvenient to wear on the legs, causing considerable inconvenience to users. Existing equipment has limitations in its ability to adjust the size of the device to accommodate different body types, such as waist width and leg length. This may not meet the needs of some users for leg training and may also make it difficult to tighten and secure the device to accommodate the differences in leg thickness. As a result, users may detach from the device during leg training, leading to falls. Therefore, we propose a leg training strap that is easy to wear. Utility Model Content
[0003] The purpose of this utility model is to provide a leg training strap that is easy to wear. By using a fixed frame, it solves the problem that the device is not good at freely adjusting the wearing size according to the waist width and leg length of users of different body types, which may not meet the wearing needs of some users for leg training. It is also not good at tightening and fixing according to the differences in the thickness of different users' legs, which may cause the user to detach from the device during leg training and cause the user to fall.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a leg training strap that is easy to wear, comprising several foot covers, each foot cover having an extension seat fixedly connected to its outer wall. A support rod is fixedly connected to the top outer wall of each extension seat. A knob is rotatably connected to the inner wall of each extension seat. A threaded rod is fixedly connected to the top outer wall of the knob. An extension rod is throttlely connected to the outer wall of the threaded rod. The outer wall of the extension rod is slidably connected to the inner wall of the support rod. A pivot block is rotatably connected to the inner wall of the end of the extension rod away from the knob. A connecting rod is rotatably connected to the outer wall of the pivot block. An adjustment mechanism is provided on the outer wall of the connecting rod. The adjustment mechanism includes several fixed frames, the outer walls of which are rotatably connected to the outer wall of the connecting rod. A slide rail is slidably connected to the outer wall of each fixed frame. A rotating shaft plate is rotatably connected to the inner wall of each fixed frame. A displacement block is rotatably connected to the inner wall of the rotating shaft plate at the end away from the fixed frame. A threaded rod is drivenly connected to the inner wall of the displacement block. A slide rail is rotatably connected to the outer wall of the threaded rod. The threaded rod passes through the slide rail to the outer wall. A knob is fixedly connected to the top outer wall of the threaded rod.
[0005] Furthermore, the outer wall of the support rod is provided with a tightening mechanism, which includes a fixing block, the inner wall of which is fixedly connected to the outer wall of the support rod.
[0006] Furthermore, a shrink sleeve is fixedly connected to the outer wall of the fixing block, and a shrink groove is formed on the inner wall of the shrink sleeve.
[0007] Furthermore, a toothed band is fixedly connected to the outer wall of the shrink sleeve, and a telescopic sleeve is fixedly connected to the outer wall of the shrink sleeve.
[0008] Furthermore, a telescopic rod is slidably connected to the inner wall of the telescopic sleeve, and a spring is fixedly connected to the outer wall of the telescopic sleeve.
[0009] Furthermore, a second rotating shaft block is fixedly connected to the outer wall of the end of the spring away from the telescopic sleeve, and the outer wall of the second rotating shaft block is fixedly connected to the outer wall of the telescopic rod.
[0010] Furthermore, a slider is rotatably connected to the outer wall of the second rotating shaft block, and a button is slidably connected to the outer wall of the slider.
[0011] Furthermore, the outer wall of the button is rotatably connected to several pivot seats, and the outer wall of the pivot seats is fixedly connected to the outer wall of the shrink sleeve.
[0012] This utility model has the following beneficial effects: 1. This utility model, by setting up a fixed frame, allows for easy adjustment of the extension rod's height by simply rotating a knob. The knob rotates the threaded rod, which in turn moves the extension rod. The height of the extension rod determines the wearing height of the device. The fixed frame secures the user's waist. To increase the spacing between the fixed frames, simply rotate knob two clockwise. Knob two rotates the threaded rod two, which in turn moves the displacement block downwards. The displacement block then rotates several rotating shaft plates, which in turn move the fixed frames. Once the fixed frames have moved further apart to a suitable position, rotating knob two can be stopped. This allows for free adjustment of the device's wearing size to suit different body types, including waist width and leg length, thus meeting the leg training needs of most users and indirectly improving the device's versatility.
[0013] 2. This utility model incorporates a locking strap that secures the user's thighs and calves. To adjust the tightness of the strap, simply press the button at the raised end. The button moves several sliders, which in turn move a telescopic rod, compressing a spring. Once the button is rotated to a certain angle and the strap is no longer pressed, the strap can move freely within the compression groove to adjust the tightness. After moving the strap to the desired position, releasing the button causes the spring to return the telescopic rod to its original position. The telescopic rod then moves the sliders back to their original position, which in turn moves the button back to its original position, thus pressing the strap and preventing it from moving. This design allows for appropriate and stable tightening and fixation to accommodate different leg sizes, preventing the user from detaching from the equipment and falling during leg training.
