[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-Figure 4 A leg training device as shown, comprising:

[0027] A seat 1, a fixing groove 2 is provided at the bottom of the seat 1, two limiting grooves 3 are provided at the bottom of the seat 1, and a fixing block 4 is fixedly connected to the bottom of the seat 1;

[0028] The moving assembly includes a bidirectional screw rod 5 rotatably connected to a fixed block 4. The fixed block 4 is provided, and the fixed block 4 can support the bidirectional screw rod 5 to prevent the bidirectional screw rod 5 from deviating and falling when rotating, thereby ensuring the stable use of the bidirectional screw rod 5;

[0029] The two-way screw rod 5 is externally threaded with two limit blocks 6, the bottoms of the two limit blocks 6 are hinged with a rotating rod 7 through a pin shaft, and the bottom of the rotating rod 7 is hinged with a dovetail block 8 through a pin shaft;

[0030] The training component includes a spring 9 fixedly connected to the bottom of the dovetail block 8, the bottom end of the spring 9 is fixedly connected to a moving block 10, the moving block 10 is internally threadedly connected to a threaded rod 11, and the threaded rod 11 is externally rotatably connected to a support block 12.

[0031] Two T-shaped blocks 13 are slidably connected in the fixed groove 2, and the two T-shaped blocks 13 are hinged with a connecting block 14 through a pin shaft. The bottom of the connecting block 14 is fixedly connected with a fixed leg 15. A plurality of air holes are provided in the seat 1, and a dovetail groove 16 is provided on the rear side of the fixed leg 15. By providing the dovetail groove 16, and the mutual cooperation between the dovetail groove 16 and the dovetail block 8, the dovetail block 8 can be prevented from being offset and stuck when moving, thereby ensuring the stable movement of the dovetail block 8;

[0032] The front end of the dovetail block 8 is slidably connected in the dovetail groove 16, the support block 12 is fixedly connected to the rear side of the fixed leg 15, the top of the threaded rod 11 and the left end of the bidirectional screw rod 5 are both provided with a stopper 17, and the tops of the two limit blocks 6 are respectively slidably connected in the two limit grooves 3. By setting the limit grooves 3, and the cooperation between the limit grooves 3 and the limit blocks 6, it is possible to avoid the limit blocks 6 from being offset and stuck during movement, thereby ensuring the stable movement of the limit blocks 6;

[0033] The bottom end of the threaded rod 11 and the right end of the bidirectional screw rod 5 are both provided with handles, the top of the seat 1 is fixedly connected with two armrests, the bottom of the seat 1 is fixedly connected with a support frame, and the front side of the fixed leg 15 is provided with a fixing clamp 18.

[0034] The working principle of the utility model is:

[0035] When using the device, first, the handle located at the top can be rotated according to the patient's body shape. The handle drives the bidirectional screw rod 5 to rotate synchronously, so that the two limit blocks 6 drive the rotating rod 7 and the dovetail block 8 to move synchronously in the limit groove 3, and the T-shaped block 13 drives the connecting block 14 and the fixed leg 15 to move synchronously. When the fixed leg 15 moves to a suitable position, the patient's leg is placed in the fixed leg 15, and the leg is fixed by the fixing clamp 18. Then, the two handles located at the bottom can be rotated, so that the handle drives the threaded rod 11 to rotate, and the moving block 10 moves upward, and the contraction length of the spring 9 can be adjusted, so as to adjust the training intensity. After that, when the fixed leg 15 is rotated, the dovetail block 8 is driven to move synchronously and slide upward in the dovetail groove 16, so that the spring 9 is in a stretched state, and one training is completed. Then, the above movement can be repeated.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
