[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 4 , In the utility model: A recumbent lower limb rehabilitation device for patients with coronary heart disease, comprising a bed 1, a seat 2 is fixedly connected to the top of the bed 1, a slide groove 3 is opened on the top of the bed 1, and a screw rod 4 is rotatably connected to the inner wall of the slide groove 3, a motor 5 is fixedly connected to the right side of the bed 1, the output shaft of the motor 5 is fixedly connected to the screw rod 4, a slider 6 is sleeved on the screw rod 4 and threadedly connected thereto, and two connecting blocks 7 are detachably connected to the right side of the slider 6 by bolts, a slide plate 8 is slidably connected to the top of the bed 1, and the bottom of the slide plate 8 is fixedly connected to the two connecting blocks 7 respectively, a vertical slot 9 is opened on the left side of the slide plate 8, and the inner wall of the vertical slot 9 is rotatably connected to the It is connected to a threaded rod 10, and a motor 2 11 is fixedly connected to the front of the skateboard 8. The output shaft of the motor 2 11 is fixedly connected to the threaded rod 10. Two moving blocks 12 threadedly connected thereto are sleeved on the threaded rod 10. Two track grooves 13 are provided on the left side of the skateboard 8. Blocks 14 are slidably connected to the inside of the two track grooves 13. A placement box 15 is fixedly connected between two adjacent blocks 14. Two elastic bands 16 are fixedly connected to the two placement boxes 15. Screws 17 rotatably connected to the two placement boxes 15 are inserted on the two placement boxes 15. One end of the two screws 17 is respectively inserted into the two moving blocks 12 and threadedly connected thereto.

[0027] In the present invention, when in use, the patient first sits on the seat 2, then bends his legs and inserts his feet into the placement box 15 respectively. The elastic band 16 can fix the soles of the feet in the placement box 15. At this time, the preparation work is completed, and then the user turns on the motor 15. The motor 15 will drive the screw rod 4 to rotate. Since the screw rod 4 is threadedly connected to the slider 6, the rotation of the screw rod 4 will drive the slider 6 to slide along the inner wall of the slide groove 3. During the movement of the slider 6, the slider 6 will drive the slide plate 8 to move through the connecting block 7. After the slide plate 8 moves, it will move through the placement box 15. Then the patient's legs will be straightened. After the patient's legs are straightened, the user turns on the motor 15 in the reverse direction. At this time, the slide plate 8 will move to the left. At this time, the patient's legs will bend. With the positive and negative start of the motor 15, the patient's legs will be bent and straightened, thereby achieving anti-toxic exercise for the patient's legs.

[0028] After a period of bending and straightening exercises, the user can drive the threaded rod 10 to rotate by turning on the motor 2 11. Since the threaded rod 10 is threadedly connected to the moving block 12 and the threaded rod 10 is double-threaded, the threaded rod 10 will drive the two moving blocks 12 to move in opposite directions along the track groove 13 after rotation. The screw 17 is used to connect the placement box 15 and the moving block 12, thereby driving the two placement boxes 15 to move in opposite directions. At this time, the patient's legs will open, and then the user turns on the motor 2 11 in the reverse direction, and the patient's legs will close. Repeatedly starting the motor 2 11 in forward and reverse directions can drive the patient's legs to open and close, thereby increasing the way to exercise the patient's legs.

[0029] After a period of rehabilitation exercise, when the patient's legs have recovered to a certain extent, the user can remove the bolt and screw 17. At this time, the user can directly perform bending and straightening exercises or opening and closing exercises without the need for assistance, thereby improving the effect of the patient's lower limb exercise.

[0030] See also Figure 2 , wherein: two limit grooves 18 are opened on the top of the bed 1, the inner walls of the two limit grooves 18 are slidably connected to the limit blocks 19, and the tops of the two limit blocks 19 are fixedly connected to the slide 8.

[0031] In the present invention, the arrangement of the limiting groove 18 and the limiting block 19 can limit the slide plate 8 , thereby improving the stability of the movement of the slide plate 8 .

[0032] See also Figures 1 to 3 , wherein: the inner wall of the limit groove 18 is slidably connected to two mounting blocks 20, a spring 21 is fixedly connected between the two mounting blocks 20, the right side of the right mounting block 20 is rotatably connected to an adjusting rod 22, and the right end of the adjusting rod 22 is inserted into the bed 1 and threadedly connected thereto.

[0033] In the present utility model, the user can drive the two mounting blocks 20 to move toward the limit block 19 by rotating the adjustment rod 22. At this time, after the slide plate 8 moves to the left, the limit block 19 will contact the mounting block 20 on the left. If the user wants to straighten his legs, he needs to overcome the elastic force of the spring 21, thereby increasing the intensity of the patient's lower limb exercise and improving the practicality of the device.

[0034] See also Figure 4 , wherein: a screw hole 23 is opened on the placement box 15, and the inner wall of the screw hole 23 is adapted to the thread of the screw rod 17.

[0035] In the present invention, the setting of the screw hole 23 can place the screw 17, and after the screw 17 is screwed into the screw hole 23, the screw 17 will contact the slide plate 8. When the user performs lower limb opening and closing training, the user needs to overcome the friction between the screw 17 and the slide plate 8, thereby increasing the intensity of the patient's lower limb exercise and improving the practicality of the device.

[0036] See also Figures 1 to 3 , wherein: the right side of the seat 2 is fixedly connected with a backrest 24, and the top of the seat 2 is fixedly connected with a seat cushion 25.

[0037] In the present invention, the arrangement of the backrest 24 and the seat cushion 25 can improve the comfort of the patient when using the device, thereby improving the practicality of the device.

[0038] See also Figure 1 , wherein: a controller 26 for controlling the opening and closing of motor 1 5 and motor 2 11 is fixedly connected to the top of the bed 1.

[0039] In the present invention, the configuration of the controller 26 can facilitate the user to control the on and off of the motor 1 5 and the motor 2 11, thereby improving the practicality of the device.

[0040] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
