[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] Example 1

[0024] like Figure 1-3 As shown, this utility model provides a fracture rehabilitation training tensioner, including a fixation plate 1, a base 2 on the upper surface of one end of the fixation plate 1, an operation panel 201 mounted on the top of the base 2, slide rails 3 on both sides of the fixation plate 1, movable blocks 301 on the surface of the slide rails 3, a fixing rod 4 mounted on the top of the movable block 301, a movable shaft 401 mounted on the top of the fixing rod 4, a connecting rod 5 on the side away from the fixing rod 4, and a rotating shaft 501 mounted on the top of the connecting rod 5. An action component 6 is provided between the moving shafts 501. The action component 6 protrudes upward at the middle of the slide rail 3 based on the moving block 301, and the action component 6 is used to drive the limb movement. A moving groove 7 is installed in the middle of the fixed rod 4. A telescopic spring 701 is installed at one end of the moving groove 7. A connecting strip 702 is installed at one end of the telescopic spring 701. A connecting frame 703 is installed at one end of the connecting strip 702. A buckle 704 is provided on the inner side of the connecting frame 703. The connection relationship between the buckle 704 and the fixed plate 1 is a fixed connection.

[0025] Its device is as follows Figure 1 As shown, when the leg is placed in the motion component 6, the motion based on the moving block 301 can change as follows: Figure 2In this form, the telescopic spring 701 is shortened, and the user can remove the connecting frame 703 from the buckle 704. When the user moves their leg again while holding the connecting frame 703 with a single hand, the hand will also generate a pulling force due to the movement of the moving block 301. When the leg is straightened, the hand generates a pulling force, and after the hand pulls, the leg changes to a bent state, thus forming a coordinated effect between the hand and the leg. Since the pulling force generated by the telescopic spring 701 is provided by the moving block 301 and the fixed rod 4, and is not directly exerted by the user, if the user cannot hold the connecting frame 703, the extension distance of the telescopic spring 701 can be adjusted in time by the operation panel 201.

[0026] Furthermore, the central part of the motion assembly 6 includes a bending shaft 601, with symmetrical side plates 602 at both ends of the bending shaft 601. The ends of the side plates 602 are rotatably connected to both ends of the bending shaft 601. The rear side of the bending shaft 601 is hinged to the moving shaft 401 via the side plates 602, and the front side of the bending shaft 601 is hinged to the rotating shaft 501 via the side plates 602. A crossbar 603 is installed on the inner side of both side plates 602, and a nylon strap 604 is installed in the middle of the crossbar 603. Figure 1 and 2 As shown, the motion assembly 6 is also activated by the moving block 301 and the fixed rod 4. The side plate 602 at the rear end of the bending shaft 601 rotates via the top rotating shaft 501 of the fixedly installed connecting rod 5, and the side plate 602 at the front end also rotates at both ends of the torsion shaft 402, causing the bending shaft 601 with a fulcrum at the bottom to move upward, forming a motion as shown in the diagram. Figure 2 The nylon strap 604 in the middle of the side panel 602 will bend downwards when the user places their limbs on it, thus providing better comfort.

[0027] Furthermore, a torsion shaft 402 is installed in the middle of the moving shaft 401, and a foot plate 403 is installed at the top of the torsion shaft 402. A fixing layer 404 is provided on the surface of the foot plate 403 for fixing the limb. The torsion shaft 402 includes a torsion spring inside; thus, the foot plate 403 is in a normal state. Figure 1 As shown, when a user needs to move their ankle or wrist, they can press their wrist downwards toward the base 2 until it touches the base 2, and then release it at the footplate 403 to return to its original position.

[0028] The movable block 301 includes a drive motor and gears inside, and the side wall of the slide rail 3 includes a rack. The gears and racks are meshed together. The movable block 301 is mainly connected to the inside of the base 2. The operation of the drive motor is controlled by the operation panel 201, so that the movable block 301 moves back and forth in the slide rail 3.

[0029] The surface of the fixing layer 404 includes Velcro, and a limiting plate 405 is installed at the bottom of the fixing layer 404, so that when the user's foot is placed on the fixing layer 404, the instep is fixed by Velcro, and the limiting plate 405 can also be used to place the heel.

[0030] Working principle:

[0031] This utility has multiple ways of use. One of them is to place the foot on the action component 6 and fix the sole of the foot on the foot plate 403. By controlling the operation panel 201, the moving block 301 moves in the slide groove 203, so that the leg can form a stretching effect of bending and straightening.

[0032] Since there are further movable slots 7 on both sides of the fixed plate 1 that move together with the movable block 301 and the fixed rod 4, after the telescopic spring 701 is shortened, the user can remove the connecting frame 703 on one side from the buckle 704 and pull it by hand. When the leg exerts force or the movable block 301 assists in moving, the hand will also generate pulling force.

[0033] Furthermore, on this basis, the other foot can be placed on the other side of the moving groove 7, with the heel placed inside the moving groove 7. As the foot on the action component 6 continuously generates gravity downwards, the other foot can also step forward from the side to move backwards on the moving groove 7 until both sides of the telescopic springs 701 are stretched, thus forming a coordinated movement effect of the user's limbs. The entire movement can be completed by the moving block 301 alone, achieving the tension effect of rehabilitation without the need for complex structural design.

[0034] Example 2

[0035] like Figure 3 As shown, the difference from Embodiment 1 is that a pressure sensor 8 is provided on the surface of the base 2 near the foot plate 403. The pressure sensor 8 and the base 2 are electrically connected. The base 2 includes an MCU microcontroller chip, a wireless connection module and a storage module. The operation panel 201 and the base 2 are electrically connected.

[0036] An insertion port 202 is provided between the side of the operation panel 201 and the base 2. The operation panel 201 and the base 2 are electrically connected through the insertion port 202. A sliding groove 203 is provided between the bottom of the operation panel 201 and the base 2. The operation panel 201 and the sliding groove 203 are slidably connected.

[0037] Since the user cannot control the moving block 301 through the operation panel 201 when it is moving as in Embodiment 1, especially when the user is using it alone, the operation panel 201 is made into a detachable module through the provided socket 202 and slide 203 structure. The operation panel 201 includes a lithium battery. After being detached, the operation panel 201 can be connected to the wireless connection module inside the base 2 based on the internal wireless transmission module. The moving length of the moving block 301 can be controlled by the operation panel 201.

[0038] A pressure sensor 8 is also installed at the base 2. When the foot plate 403 rotates, the pressure sensor 8 can transmit the pressure generated by the foot plate 403 to the storage module inside the base 2 for recording. After the data is recorded, it can be viewed in real time on the display screen on the operation panel 201 to realize the monitoring of the user's health data.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
