Technical Field
[0001] The utility model relates to the technical field of orthopedic rehabilitation training devices, in particular to a training device. Background Art
[0002] Orthopedics is one of the most common departments in major hospitals, mainly studying the anatomy, physiology and pathology of the musculoskeletal system, and using drugs, surgery and physical methods to maintain and develop the normal form and function of this system. With the progress of technology, through orthopedic surgery and other treatments, most common orthopedic diseases can be cured.
[0003] Considering that during orthopedic surgery, the cells, nerves and muscles of the injured part will be damaged, so a rehabilitation training device is needed for adjuvant treatment. And the conditions and training needs of each patient are different, so some recovery training devices with special structural functions can be applied.
[0004] Generally, the traditional recovery training device needs to be adjusted to an appropriate position before the patient uses it. During the adjustment process, since the patient needs to be in the designated position of the training device, for patients with foot injuries, the patient needs to grab items such as crutches with both hands to ensure that they can walk. Therefore, the patient cannot adjust the training device first, which leads to the inability to complete the adjustment by themselves and requires the cooperation of nursing staff to achieve the adjustment purpose. Moreover, the training device generally cannot adjust the training intensity, so it is impossible to carry out rehabilitation training differently. And to increase the intensity through external objects, the cooperation of nursing staff for taking, disassembling and assembling is required and cannot be completed by oneself. Content of the Utility Model

Detailed implementation manners
[0031] The following will describe the present utility model in detail with reference to the accompanying drawings.
[0032] In order to make the purpose, technical solutions and advantages of the present utility model more clear, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0033] Embodiment 1
[0034] As Figure 1-2A training device as shown includes a base 1, on which there is a height adjustment device 2 capable of height adjustment. The height adjustment device 2 is provided with a first turntable 24, and inside the height adjustment device 2, there is also a displacement device 21 capable of lifting movement. The displacement device 21 is connected to the first turntable 24, and a pedal device 3 is also provided on the displacement device 21. In this way, when a patient uses the device, if they feel that the height of the pedal device 3 is not suitable, they can independently control the displacement device 21 by rotating the first turntable 24, so that the displacement device 21 makes a lifting movement inside the height adjustment device 2. Since the displacement device 21 is connected to the pedal device 3, when the displacement device 21 moves, it can drive the pedal device 3 to move synchronously, enabling the patient to adjust the height of the pedal device 3 without moving their own position.
[0035] Furthermore, the height adjustment device 2 is connected to a horizontal adjustment device 4. The horizontal adjustment device 4 includes a linkage component 45 and a sliding component 44. The linkage component 45 includes a second screw rod 41. One end of the second screw rod 41 is rotatably connected to the displacement device 21, and the other end is threadedly connected to the sliding component 44. The bottom of the sliding component 44 is connected to a lifting seat 5, and the lifting seat 5 is slidably connected to the base 1. When the patient has adjusted the height of the pedal device 3 and finds that the distance between the lifting seat 5 and the pedal device 3 is too far, they can rotate the second screw rod 41. Since one end of the second screw rod 41 can be rotatably connected to the displacement device 21 and the displacement device 21 is limited in the horizontal position, when the patient rotates the second screw rod 41, the sliding component 44 threadedly connected to the second screw rod 41 will receive a force in the horizontal direction. Since the sliding component 44 is connected to the lifting seat 5 and the lifting seat 5 is slidably connected to the base 1, when the sliding component 44 receives the force applied in the horizontal direction, it will drive the lifting seat 5 to displace, thereby achieving the adjustment of the horizontal position of the lifting seat 5.
[0036] Specifically, the height adjustment device 2 includes a mounting frame 22 fixedly connected to the base 1. The mounting frame 22 is provided with a chute 221 along its vertical direction, and the displacement device 21 is arranged in the chute 221, so that the displacement device 21 can make a lifting movement in the chute 221. The displacement device 21 includes a first screw hole block 211, the first screw hole block 211 is provided with a first screw rod 212 along the vertical direction, and the first screw rod 212 is threadedly connected to the first screw hole block 211.
[0037] Further, a sliding portion 222 is also provided inside the mounting bracket 22. There are two sliding portions 222, which are symmetrically arranged on both sides of the sliding groove 221. On the first screw hole block 211 arranged in the sliding groove 221, first sliding blocks 213 are symmetrically provided, and the first sliding blocks 213 are adapted to the sliding portion 222, so that the first sliding blocks 213 can move along the sliding portion 222. And because the sliding portion 222 limits the first sliding blocks 213, the first screw hole block 211 can be prevented from rotating. Thus, when the operator rotates the first screw 212 through the first turntable 24, the first screw hole block 211 threadedly connected to the first screw 212 cannot rotate and then starts to perform a lifting motion;
[0038] Further, a pedal device 3 is connected to one end of each first sliding block 213 away from the first screw hole block 211. This can ensure that the patient can adjust the height of the foot pedal according to their own needs when adjusting the height of the foot pedal, as Figure 1-2 shown.
[0039] As described above, a pair of auxiliary handrails 25 are provided on the mounting bracket 22, so that the patient can use the training device by grasping the auxiliary handrails 25 by themselves.
[0040] As described above, the first screw hole block 211 and the linkage member 45 are rotatably connected. The linkage member 45 includes a second screw 41 for driving. One end of the second screw 41 is connected to the first screw hole block 211, and a bearing is provided at the connection. Through the bearing, the second screw 41 can rotate after being connected to the first screw hole block 211;
[0041] Further, a sleeve 42 is provided at one end of the second screw 41 away from the first screw hole block 211, and the sleeve 42 is threadedly connected to the second screw 41. A baffle 43 is provided at one end of the sleeve 42 away from the second screw 41. A sliding member 44 is provided at one end of the baffle 43 not connected to the sleeve 42. The sliding member 44 is connected to a lifting seat 5, and the lifting seat 5 is slidably connected to the base 1;
[0042] Since the mounting bracket 22 cannot move, the movement of the first screw hole block 211 is all along the sliding groove 221. When the second screw 41 is rotatably connected to the first screw hole block 211, the patient rotates the second screw 41. Since the horizontal position of the first screw hole block 211 is fixed, when the second screw 41 rotates, the sleeve 42 threadedly connected to the second screw 41 will receive a force applied in the horizontal direction. And since the sleeve 42 is connected to the sliding member 44 through the baffle 43, and the sliding member 44 is provided with a lifting seat 5, and the lifting seat 5 is slidably connected to the base 1 (that is, when the patient can control the displacement of the sleeve 42 through the second screw 41, so that the lifting seat 5 is displaced on the base 1), as Figure 1 shown.Figure 6 as shown
[0043] As described above, the linkage member 45 includes a second turntable 451, which is fixedly connected to the second screw 41. Such a setting enables the patient to control the rotation of the second screw 41 through the second turntable 451, as Figure 6 shown
