[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3 The arm extension rehabilitation clamp with a damping device shown in the figure comprises a machine base 1, a mounting groove 2 is provided on the inner side of the top of the machine base 1, a rotating base 3 is fixedly connected to both ends of the inner wall of the mounting groove 2, a damping rotating shaft is fixedly connected to the inner side of the rotating base 3, a rotating plate 4 is fixedly connected to the axis of the damping rotating shaft, the rotating base 3 is rotatably connected to the rotating plate 4 through the damping rotating shaft, and a stretching exercise plate 7 is fixedly connected to the top of the rotating plate 4;

[0020] A fixed groove 8 is provided inside the machine base 1, and a rack 81 is slidably connected to the inner wall of the fixed groove 8. A fan gear 41 is fixedly connected to the bottom end of the rotating plate 4, and the fan gear 41 and the rack 81 are meshed with each other. A spring cylinder 9 is fixedly connected to the inside of the fixed groove 8, and a spring 91 is placed inside the spring cylinder 9. An output rod 92 is slidably connected to one end of the inner wall of the spring cylinder 9, and an adjusting rod 93 is slidably connected to the other end of the inner wall of the spring cylinder 9. One end of the output rod 92 is fixedly connected to the rack 81. A handle 6 is rotatably connected to one side of the machine base 1, and one end of the handle 6 is fixedly connected to a screw rod 61. A sliding groove 62 is provided inside the machine base 1, and the sliding grooves 62 and 63 are slidably connected. The screw rod 61 and the adjusting rod 93 are connected by a threaded sleeve.

[0021] When in use, the patient places the elbow of the arm on the inner wall of the limiting groove 13 at the top of the latex pad 12, and then holds the handle 73 with the palm of the hand in a forward or reverse grip, and then the forearm can be rotated outward to perform stretching exercises, and the forearm can be rotated inward to perform inward rotation rehabilitation exercises;

[0022] When rotating, the rotating plate 4 drives the sector gear 41 to rotate at the top of the rack 81, thereby driving the rack 81 and the output rod 92 to move linearly, thereby stretching or squeezing the spring 91, and then performing rehabilitation training. After each stretching or compression of the spring 91, when the hand is released, it is slowly reset under the action of the damping shaft, thereby effectively avoiding rapid reset due to the elastic force of the spring 91, causing arm damage;

[0023] When holding the handle 73, it is convenient to slide up and down on the inner wall of the limiting slide groove 71 according to the patient's forearm, which is convenient for adjustment. At the same time, during the rotation process, when the elbow position is fixed, the position of the hand often changes slightly. Therefore, the sliding mode of the limiting slide plate 72 is adopted to effectively improve the patient's exercise experience.

[0024] In addition, when different exercise angles are needed, the handle 6 is rotated and then the screw rod 61 is used to push the adjusting rod 93 to slide on the inner wall of the spring tube 9, and then the spring 91 and the output rod 92 drive the rack 81 to slide, and the fan gear 41 is used to change the angle of the rotating plate 4 and the stretching exercise plate 7, so as to facilitate the patient to perform flexion and extension at different angles and improve the patient's exercise experience. In addition, when the spring 91 is squeezed or stretched and the rack 81 is moved to the limit position, the deformation force of the spring 91 will be increased, thereby changing the patient's exercise force. However, the exercise direction and angle at this time are relatively single, and only flexion and extension exercises can be performed at the maximum angle in one direction.

[0025] The bottom end of the base 1 is fixedly connected to the bottom plate 5 by bolts for disassembly and assembly and inspection of internal components. Placement grooves 11 are provided on both sides of the top of the base 1, and latex pads 12 are placed on the inner walls of the placement grooves 11. Limiting grooves 13 are provided on the top of the latex pads 12. Limiting slide grooves 71 are provided on both sides of the stretching exercise plate 7. The inner walls of the limiting slide grooves 71 are slidably connected to the limiting slide plate 72. A handle 73 is fixedly connected to one side of the limiting slide plate 72. The handle 73 can be used for the patient's hand to perform forward or reverse grip for arm flexion and extension exercises. One end of the spring 91 is fixedly connected to one end of the adjusting rod 93, and the other end of the spring 91 is fixedly connected to one end of the output rod 92.

[0026] In summary, the utility model has the following working principle: when in use, the patient places the elbow of the arm on the inner wall of the limit groove 13 at the top of the latex pad 12, and then holds the handle 73 with the palm of the hand in a forward or reverse grip, and then the forearm can be rotated outward to perform stretching exercises, and the forearm can be rotated inward to perform inward rotation rehabilitation exercises;

[0027] When rotating, the rotating plate 4 drives the sector gear 41 to rotate at the top of the rack 81, thereby driving the rack 81 and the output rod 92 to move linearly, thereby stretching or squeezing the spring 91, and then performing rehabilitation training. After each stretching or compression of the spring 91, when the hand is released, it is slowly reset under the action of the damping shaft, thereby effectively avoiding rapid reset due to the elastic force of the spring 91, causing arm damage;

[0028] When holding the handle 73, it is convenient to slide up and down on the inner wall of the limiting slide groove 71 according to the patient's forearm, which is convenient for adjustment. At the same time, during the rotation process, when the elbow position is fixed, the position of the hand often changes slightly. Therefore, the sliding mode of the limiting slide plate 72 is adopted to effectively improve the patient's exercise experience.

[0029] In addition, when different exercise angles are needed, the handle 6 is rotated and then the screw rod 61 is used to push the adjusting rod 93 to slide on the inner wall of the spring tube 9, and then the spring 91 and the output rod 92 drive the rack 81 to slide, and the fan gear 41 is used to change the angle of the rotating plate 4 and the stretching exercise plate 7, so as to facilitate the patient to perform flexion and extension at different angles and improve the patient's exercise experience. In addition, when the spring 91 is squeezed or stretched and the rack 81 is moved to the limit position, the deformation force of the spring 91 will be increased, thereby changing the patient's exercise force. However, the exercise direction and angle at this time are relatively single, and only flexion and extension exercises can be performed at the maximum angle in one direction. In this way, the overall workflow of the device is completed.

[0030] 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.
