Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] When in use, the legs are placed on the fixing frame, and after the legs are positioned and fixed by the fixing straps, the legs are trained by changing the angle of the fixing frame.

[0043] In the related art, rehabilitation training of the lower limbs is generally performed by gradually changing the leg posture. However, the structure of the lower limb training device is relatively complex. Although it can achieve good training effects, in actual use, it is overall heavy and inconvenient to adjust the position of the lower limb training device. It has certain limitations and is inconvenient to use.

[0044] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a lower limb training device with a positioning function. When it is needed, it is only necessary to use the driving mechanism to adjust the position of the slider 22, so that the placement frame 12 can be telescoped and folded to achieve lower limb training. At the same time, the position of the training device can be easily adjusted through the moving wheel 32, which is more convenient and quick, thereby improving the convenience of the device.

[0045] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Combination Figure 1-Figure 4 The embodiment of the present application provides a lower limb training device with a positioning function, including a frame assembly 1; the frame assembly 1 includes: a base 11 on which a placement frame 12 is arranged; a training assembly 2 is arranged on the base 11; the training assembly 2 includes: a slide 21 symmetrically opened on the base 11; a slider 22 is slidably connected to the slide 21; a connecting rod 23 is rotatably connected to the slider 22; a control box 24 is arranged on the top of the base 11; a switch 25 is arranged on the top of the control box 24, and a driving mechanism and a power supply are arranged in the base 11;

[0047] The bottom of the base 11 is provided with an adjustment assembly 3; the adjustment assembly 3 comprises: a box 31 fixedly connected to the bottom of the base 11; an adjustment plate 33 slidably connected to the box 31; a moving wheel 32 is provided at the bottom of the adjustment plate 33; and an electric push rod 34 is fixedly connected to the box 31;

[0048] A sliding assembly 4 is provided on the base 11; the sliding assembly 4 includes: a fixed seat 41 fixedly connected to the base 11; a push rod 42 slidably connected in the fixed seat 41; a push block 43 fixedly connected to the outer side of the push rod 42 and slidably connected in the fixed seat 41; a spring 44 is provided in the fixed seat 41, and the two ends of the spring 44 are respectively fixedly connected to the push block 43 and the fixed seat 41; a fixed plate 45 is fixedly connected to the bottom of the push rod 42; a slide groove 46 is opened on the box body 31, and the fixed plate 45 passes through the box body 31 through the slide groove 46; a fixed block 47 is fixedly connected to the bottom of the slider 22.

[0049] When in use, after the moving wheel 32 contacts the ground or the carrying platform, the base 11 is directly pushed to adjust the position of the base 11, and the patient's lower limbs are fixed to the placement rack 12 through the straps. The electric push rod 34 is turned on through the switch 25 on the control box 24 to shrink the output end. The gravity of the base 11 and the equipment thereon acts between the box body 31 and the adjustment plate 33, so that the moving wheel 32 drives the adjustment plate 33 to slide into the box body 31. Then, the driving mechanism is turned on through the control box 24 to adjust the position of the slider 22, so that the slider 22 pushes the placement rack 12 through the connecting rod 23. 2-shaped telescopic folding is used to train the lower limbs. When the driving mechanism is turned on, the slider 22 slides horizontally in the slide groove 21. When the slider 22 slides to the leftmost side, the placement frame 12 is completely folded. When the slider 22 slides to the rightmost side, the placement frame 12 is extended. At this time, the driving mechanism is continued to be used to make the slider 22 push the push rod 42 to slide downward in the fixed seat 41 through the fixed block 47, and push the adjustment plate 33 while sliding in the slide groove 46 through the fixed plate 45, so that the adjustment plate 33 pushes the moving wheel 32 to slide out from the bottom of the base 11, thereby completing the training, and the position of the base 11 can be easily adjusted;

[0050] Specifically, the driving mechanism is composed of a motor, a screw and a sensor. There are always three sensors to monitor the position of the slider 22. When the slider 22 slides to the position of the first sensor, the placement frame 12 is folded. When the slider 22 slides to the position of the second sensor, the placement frame 12 is extended. At this time, the motor screw is continued to be used to make the slider 22 continue to slide, so that the slider 22 reaches the position of the third sensor. At this time, the slider 22 and the fixed block 47 push the push rod 42, the fixed plate 45 and the adjustment plate 33. The first sensor and the third sensor are arranged on the outside, and the second sensor is arranged in the middle. The first sensor is close to the human body, and the third sensor is close to the control box 24. Because the coordinated use of the screw motor and the sensor belongs to the prior art, it will not be elaborated here.

[0051] In some embodiments, the adjustment assembly 3 further includes: a guide rod 35 fixedly connected to the box body 31, and the guide rod 35 passes through the adjustment plate 33, so that the adjustment plate 33 can only slide longitudinally, making the moving wheel 32 more stable when moving.

[0052] In some embodiments, the fixed seat 41, the push rod 42, the push block 43 and the spring 44 are a group, two groups are arranged on the base 11, and the two ends of the fixed plate 45 are respectively fixedly connected to the two springs 44, so that the two sliders 22 push the two push rods 42 and one fixed plate 45 through the two fixed blocks 47 respectively, so that the adjustment plate 33 is evenly stressed.

[0053] In some embodiments, the push rod 42 is provided with an inclined surface to facilitate the fixing block 47 to push the push rod 42 .

[0054] In some embodiments, an auxiliary component 5 is provided in the base 11; the auxiliary component 5 includes: a positioning rod 51 slidably connected in the base 11 and fixedly connected to the placement rack 12; a fastening bolt 52 is threadedly connected to the positioning rod 51, and one end of the fastening bolt 52 is tightly pressed against the positioning rod 51.

[0055] When in use, the fixing bolt 52 is grasped to separate one end thereof from the positioning rod 51, and then the placement rack 12 is pulled to slide out of the positioning rod 51, and the initial position of the placement rack 12 is adjusted, thereby increasing the adjustment range.

[0056] In some embodiments, the positioning rod 51 is a round-headed rod, and the positioning rod 51 is separated from the base 11 .

[0057] In some embodiments, a limiting assembly 6 is provided on the adjustment plate 33; the limiting assembly 6 includes: a rod body 61 fixedly connected to the top of the adjustment plate 33; a limiting groove 62 is opened on the base 11, and the rod body 61 passes through the box body 31, the adjustment plate 33 and the base 11 through the limiting groove 62; a limiting hole 63 is opened on the outside of the positioning rod 51, and one end of the rod body 61 is inserted into the limiting hole 63.

[0058] During use, when the adjustment plate 33 slides up and down, the rod body 61 is pushed to interact up and down in the limit groove 62. When the adjustment plate 33 slides upward, the rod body 61 slides out of the limit hole 63, and the lock of the positioning rod 51 is cancelled. Conversely, when the adjustment plate 33 slides downward, the rod body 61 is inserted into the limit hole 63 to fix the position of the positioning rod 51. When the driving mechanism is used for lower limb training, the moving wheel 32 is stored in the box body 31 and the rod body 61 is inserted into the limit hole 63. Conversely, after the training is completed, when the driving mechanism is reset, the moving wheel 32 slides out from the bottom of the box body 31, and the rod body 61 slides out from the limit hole 63 at the same time, which is convenient for moving and changing the position of the placement frame 12, thereby facilitating the user to remove the lower limbs from the training device.

[0059] In some embodiments, a plurality of the limiting holes 63 are provided, so that the rod body 61 can be inserted into the limiting holes 63 at different positions, thereby fixing the positioning rod 51 at multiple positions.

[0060] In some embodiments, the placement frame 12 is provided with a fixing strap. When in use, patients who cooperate can directly place their legs on the placement frame 12 for rehabilitation training. Patients who do not cooperate or cannot control themselves can perform rehabilitation training by using fixing straps to fix their legs on the placement frame 12.

[0061] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0062] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
