[0037] Example

[0038] like Figure 1 As shown, the utility model proposes a multifunctional flexion and extension device for finger rehabilitation training, including a wristband 1 sleeved on the user's wrist, and the two ends of the wristband 1 are bonded together by Velcro 11, so that the wristband 1 can be fixed on wrists of different thicknesses. An elastic box 2 is installed below the wristband 1, and one side of the elastic box 2 is connected to multiple groups of finger sleeves 4 through multiple groups of connecting rods 3. The number of connecting rods 3 and finger sleeves 4 is five, just corresponding to five fingers. The finger sleeves 4 are sleeved on the fingertips and drive the connecting rods 3 to move when the hand is opened. Each group of connecting rods 3 includes a first fixed rod 31 fixedly connected to the finger sleeves 4, and each group of connecting rods 3 also includes a second adjustment rod 32 fixedly connected to the second rotating block 74. The second adjustment rod 32 is installed with a first threaded rod 33 at one end close to the first fixed rod 31, and the first threaded rod 33 is threadedly connected to the first fixed rod 31, so that the overall length of the connecting rod 3 can be adjusted, so that the device is suitable for people with different finger lengths. At the same time, the setting of the connecting rod 3 replaces the elastic rope connection, avoiding the influence of aging after use.

[0039] For further information, see Figure 2The flexion and extension device includes an elastic component 5 for providing elastic force to exercise the finger muscles, and the elastic component 5 is arranged in the elastic box 2. The elastic component 5 includes five groups of spring chambers 51 equidistantly arranged in the elastic box 2, and a moving rod 52 is arranged in each of the five groups of spring chambers 51. One end of the moving rod 52 protrudes from the surface of the elastic box 2 and is connected to the end of the connecting rod 3 away from the finger sleeve 4, so that when the finger sleeve 4 moves, the moving rod 52 can be driven to move by the connecting rod 3. The moving rod 52 is slidably connected to the elastic box 2, so that the movement of the moving rod 52 is stable. The outer ring of each group of moving rods 52 is sleeved with a spring 53, and the spring 53 is arranged in the spring chamber 51. The end of the moving rod 52 away from the connecting rod 3 is also fixedly connected to the squeezing disk 54, and the moving rod 52 drives the squeezing disk 54 to move synchronously when moving. The squeezing disk 54 is slidably connected in the spring chamber 51. When the squeezing disk 54 moves synchronously with the moving rod 52, it slides in the spring chamber 51, and the moving rod 52 can be limited to make it move smoothly. One end of the spring 53 is fixedly connected to the extrusion disk 54. When the extrusion disk 54 moves, it squeezes the spring 53 to obtain elastic force, so that the patient is affected by the elastic force when opening his hand, thereby achieving the purpose of rehabilitation training.

[0040] Furthermore, if Figure 3As shown, the flexion and extension device also includes an adjustment mechanism 6 for adjusting the elastic force of the elastic component 5, and the adjustment mechanism 6 is installed on the elastic box 2. The adjustment mechanism 6 includes an adjustment chamber 61 opened in the elastic box 2, and the adjustment chamber 61 is connected to the multiple groups of spring chambers 51. An adjustment plate 62 is slidably connected in the adjustment chamber 61, and the adjustment plate 62 slides smoothly in the adjustment chamber 61. Multiple groups of moving rods 52 all penetrate the adjustment plate 62 and are slidably connected in the adjustment plate 62. The moving rods 52 and the adjustment plate 62 are limited by each other when moving, and move smoothly. Two groups of first slide grooves 63 opened on the elastic box 2 are provided on the side of the adjustment chamber 61 away from the wristband 1. The two groups of first slide grooves 63 are slidably connected to the limiting blocks 64, and the limiting blocks 64 slide smoothly in the first slide grooves 63. The two groups of limiting blocks 64 are fixedly connected to the adjustment plate 62, and are used to drive the limiting blocks 64 to move synchronously when the adjustment plate 62 moves. The limit block 64 is slidably connected with a limit rod 65, and the limit block 64 is limited by the limit rod 65 when moving, so that the limit block 64 moves smoothly, and the adjustment plate 62 moves smoothly. Both ends of the limit rod 65 are fixedly connected with a fixing plate 66, and the fixing plate 66 is fixedly set on the side of the elastic box 2 away from the wristband 1. The positions of the limit rod 65 and the fixing plate 66 are fixed. A second threaded rod 67 is also rotatably connected between the two sets of fixing plates 66, and the second threaded rod 67 rotates in place. One end of the second threaded rod 67 passes through the fixing plate 66 on one side, so that the second threaded rod 67 can be rotated by a screwdriver. The outer ring of the fixing plate 66 is threadedly connected with a moving block 68, which is used to drive the moving block 68 to move along the length direction of the second threaded rod 67 when the second threaded rod 67 rotates. The moving block 68 is arranged between the two groups of fixed plates 66. The elastic box 2 is also provided with a second slide groove 69 that cooperates with the moving block 68. The moving block 68 is slidably connected in the second slide groove 69. The moving block 68 is fixedly connected to the adjustment plate 62. When the moving block 68 moves, it drives the adjustment plate 62 to move synchronously.

[0041] Finally, see Figure 4 The flexion and extension device further includes a connection assembly 7 disposed at the connection between the connection rod 3 and the moving rod 52. The connection assembly 7 includes a first fixed seat 71 fixedly connected to one end of the moving rod 52 away from the extrusion plate 54, a first rotating block 72 rotatably connected to the first fixed seat 71, a second fixed seat 73 fixedly connected to the side of the first rotating block 72 away from the first fixed seat 71, a second rotating block 74 rotatably connected to the second fixed seat 73, the connection rod 3 is fixedly connected to the second rotating block 74, the rotation axes of the first rotating block 72 and the second rotating block 74 are perpendicular to each other, so that the connection rod 3 can be deflected at multiple angles, which is convenient for driving the deflection movement of the connection rod 3 when the palm is opened.

[0042] In this embodiment, when performing rehabilitation training, the patient's palm is facing down, and the wristband 1 is placed on the patient's wrist, and the wristband 1 is fixed to the patient's wrist by Velcro 11. At this time, the first fixed rod 31 is rotated according to the length of the patient's fingers. Since the first fixed rod 31 is threadedly connected with the first threaded rod 33, the overall length of the connecting rod 3 can be adjusted, so that the position of the finger sleeve 4 is suitable for patients with different finger lengths. The patient wears five sets of finger sleeves 4 on five fingers in turn. At this time, the patient opens his palm. Due to the setting of the connecting component 7, the connecting rod 3 can be easily deflected, so that the finger sleeve 4 moves and drives the moving rod 52 to move through the connecting rod 3. At this time, the moving rod 52 slides in the elastic box 2 and drives the extrusion disk 54 to move the extrusion spring 53. Under the influence of the elastic force of the spring 53, the patient is helped to perform effective rehabilitation training and promote the recovery of finger muscles and the improvement of function. When the rehabilitation training is carried out to the later stage, the patient's hand muscles have recovered to a certain extent. At this time, a screwdriver can be used to rotate the second threaded rod 67. When the second threaded rod 67 rotates, the moving block 68 is driven to move along the length direction of the second threaded rod 67, so that the moving block 68 moves to the side away from the finger sleeve 4, and at the same time drives the adjustment plate 62 fixedly connected to the moving block 68 to move synchronously. At this time, the adjustment plate 62 moves smoothly under the limiting action of the adjustment cavity 61 and the moving rod 52, and at the same time drives the two groups of limiting blocks 64 to slide on the fixed limiting rod 65 for limiting, so that the movement of the adjustment plate 62 is more stable. At this time, the adjustment plate 62 moves and squeezes the spring 53, so that the patient can obtain a greater elastic force when the patient opens his hand to drive the moving rod 52 to move, which is suitable for rehabilitation training needs at different stages, improves the training effect, and helps patients recover finger function faster.

[0043] The above specific embodiment is only an optional embodiment of the present invention.
