[0021] This utility model embodiment provides a post-traumatic traction and stretching device, such as... Figure 1-4 As shown, the post-traumatic traction and stretching device includes: a base plate 1, with a vertical frame 2 fixed to the top of the base plate 1; a counterweight box 3 disposed on one side of the base plate 1, with a removable counterweight plate 4 inside the counterweight box 3 for counterweighting during post-traumatic traction and stretching; a mounting box 5 fixed to the top of the counterweight box 3, with a winding reel 6 rotatably mounted inside the mounting box 5, and a steel wire rope 8 disposed on the winding reel 6 for traction and stretching; a first motor 7 fixed to the mounting box 5, the output shaft of the first motor 7 being fixedly connected to the shaft of the winding reel 6 via a coupling; a gripping rod 9 mounted on one end of the steel wire rope 8, with a gripping sleeve 10 fixed on the gripping rod 9 for gripping by a person; a laterally adjustable seat 11 disposed on the base plate 1; an adjustment mechanism disposed on the base plate 1 for controlling the lateral movement of the seat 11; and an adjustable lower limb training mechanism disposed on the vertical frame 2.
[0022] In this embodiment, the base plate 1 serves as the supporting foundation for the entire device, and its stability and load-bearing capacity are crucial. A vertical frame 2 is fixed to the top of the base plate 1, providing installation positions for other components. The vertical frame 2, fixed to the base plate 1, supports and installs other key components, such as the mounting box 5 and the lower limb training mechanism. A counterweight box 3 is located on one side of the base plate 1, containing a removable counterweight plate 4. The weight of the counterweight plate 4 can be adjusted according to the patient's rehabilitation needs and training intensity, providing appropriate traction resistance. The mounting box 5 is fixed to the top of the counterweight box 3, and a winding reel 6 is rotatably mounted inside. The mounting box 5 provides protection and support for the winding reel 6. The winding reel 6 is rotatably mounted inside the mounting box 5 and has a steel wire rope 8 mounted on it. One end of the steel wire rope 8 is connected to the winding reel 6, and the other end is gripped by a gripping rod 9 for the patient to grasp. When the patient pulls forcefully, the counterweight box 3 rises, and the pull and release action achieves a traction and stretching effect. The first motor 7 is fixed on the mounting box 5, and its output shaft is fixedly connected to the shaft of the winding reel 6 via a coupling. The rotation of the first motor 7 drives the winding reel 6 to rotate, thereby controlling the winding and unwinding of the wire rope 8 and adjusting the height of the grip bar 9. The grip bar 9 is mounted on one end of the wire rope 8 for the patient to grip and perform traction and stretching. A grip sleeve 10 is fixed on the grip bar 9, increasing the comfort and stability of the grip. The seat 11 is set on the base plate 1 and can be adjusted laterally. The design of the seat 11 allows the patient to sit comfortably for rehabilitation training. The adjustment mechanism is set on the base plate 1 and is used to control the lateral movement of the seat 11. Through the adjustment mechanism, the position of the seat 11 can be adjusted according to the patient's body shape and rehabilitation needs, improving the flexibility and comfort of training. The lower limb training mechanism is set on the vertical frame 2 and can be adjusted to adapt to the training needs of different patients.
[0023] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a screw 12 rotatably mounted on the base plate 1; an assembly block 13 threaded onto the screw 12, the top of the assembly block 13 being fixedly connected to the bottom of the seat 11; and a second motor 14 fixed on the base plate 1, the output shaft of the second motor 14 being fixedly connected to the screw 12 via a coupling.
[0024] In this embodiment, the screw 12 is rotatably mounted on the base plate 1, serving as the main transmission component for adjusting the position of the seat 11. The assembly block 13 is threaded onto the screw 12, forming a threaded engagement. When the screw 12 rotates, the assembly block 13 moves along the axial direction of the screw 12. The bottom of the seat 11 is fixedly connected to the top of the assembly block 13. Therefore, when the assembly block 13 moves, the seat 11 also moves accordingly, thereby achieving seat position adjustment. The second motor 14 is fixed on the base plate 1, and its output shaft is fixedly connected to the screw 12 via a coupling. The rotation of the second motor 14 can drive the screw 12 to rotate. By driving the screw 12 to rotate through the second motor 14, the assembly block 13 and the seat 11 move along the screw axial direction, achieving automated adjustment of the seat position. This adjustment method is more convenient and accurate than manual adjustment, improving training efficiency and patient comfort. Due to the threaded engagement between the screw 12 and the assembly block 13, the seat 11 can move within a large range on the base plate 1. This allows the device to be adapted to patients of different heights and body types, meeting their personalized training needs.
[0025] In a further preferred embodiment of the present invention, the lower limb training mechanism includes: a first electric telescopic rod 15 fixed on the vertical frame 2, with a mounting shell 16 fixed on the output rod of the first electric telescopic rod 15; a slide rod 17 slidably mounted on the mounting shell 16, with a foot pedal 18 fixed on the slide rod 17 for use by a person's foot; and a spring 19 sleeved on the slide rod 17.
[0026] In this embodiment, the first electric telescopic rod 15 is fixed on the vertical frame 2 and serves as the power source for the lateral movement of the lower adjustable mounting shell 16, thereby ensuring that the foot pedal 18 is always at a suitable height for the patient; when the person applies force to step on the foot pedal 18, the elastic feedback of the spring 19 makes the patient need to overcome a certain resistance during the stepping process, which helps to enhance the strength and endurance of the lower limb muscles.
[0027] In a further preferred embodiment of this utility model, an mounting sleeve 20 is fixed on the vertical frame 2, and a second electric telescopic rod 21 is fixed on the mounting sleeve 20. A bracket 22 is fixed on both the output rod of the second electric telescopic rod 21 and the mounting sleeve 20. A guide wheel 23 is rotatably mounted on the bracket 22 for guiding the wire rope 8.
[0028] In this embodiment, the mounting sleeve 20 is fixed to the vertical frame 2, providing an installation position for the second electric telescopic rod 21. The design of the mounting sleeve 20 allows the second electric telescopic rod 21 to be securely fixed to the vertical frame 2 while maintaining a certain degree of flexibility. The output rod of the second electric telescopic rod 21, fixed to the mounting sleeve 20, can extend and retract according to a control signal. The extension and retraction of the second electric telescopic rod 21 can drive the connected components to move up and down. The bracket 22 is fixed to both the output rod of the second electric telescopic rod 21 and the mounting sleeve 20. The design of the bracket 22 allows the guide wheel 23 to be securely mounted on it while maintaining a certain degree of rotational flexibility. The guide wheel 23 is rotatably mounted on the bracket 22 and is used to guide the wire rope 8. The smooth surface of the guide wheel 23 reduces the frictional resistance of the wire rope 8 during the guiding process, allowing the wire rope 8 to move smoothly.
[0029] In a further preferred embodiment of the present invention, an assembly groove is provided on the base plate 1. The assembly groove is not only used for assembling the screw 12 and the second motor 14, but also for guiding the assembly block 13.
[0030] In this embodiment, an assembly slot is formed on the base plate 1. This assembly slot is not only used for assembling the screw 12 and the second motor 14, but also provides a guiding function for the assembly block 13. The design of the assembly slot allows components such as the screw 12, the second motor 14, and the assembly block 13 to be stably mounted on the base plate 1 and maintain a certain relative positional relationship.
[0031] In a further preferred embodiment of the present invention, a sliding hole is provided on the mounting shell 16, the sliding hole is adapted to the sliding rod 17, and a limit block is fixed on one end of the sliding rod 17.
[0032] In this embodiment, a sliding hole adapted to the slide rod 17 is formed on the mounting housing 16. This sliding hole design allows the slide rod 17 to slide smoothly within the mounting housing 16 without obstruction or jamming; a limiting block is fixed to one end of the slide rod 17. The limiting block is designed to limit the sliding range of the slide rod 17 within the mounting housing 16, preventing it from sliding out of the mounting housing 16 or moving excessively.
[0033] In a further preferred embodiment of this utility model, support columns are symmetrically fixedly installed on the bottom of the base plate 1, and foot pads are fixed on the bottom ends of the support columns to increase friction.
[0034] In this embodiment, support columns are symmetrically fixedly installed on the bottom of the base plate 1. These support columns provide stable support for the base plate 1, ensuring the stability and load-bearing capacity of the entire device. Foot pads are fixed to the bottom of the support columns. The foot pads are designed to increase friction with the ground and prevent safety hazards caused by sliding or displacement of the device during use.
[0035] In summary, the lateral adjustment mechanism adapts to patients of different heights and body types, meeting their personalized training needs. The lower limb training mechanism is mounted on the vertical frame 2 and can be adjusted to suit the training needs of different patients. The rotation of the first motor 7 drives the winding reel 6 to rotate, thereby controlling the winding and unwinding of the wire rope 8 and adjusting the height of the grip bar 9, improving the flexibility and convenience of training. The rotation of the second motor 14 drives the screw 12 to rotate, which in turn moves the assembly block 13 and the seat 11 along the screw axis, realizing the automatic adjustment of the seat position.
