Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training devices, and in particular to an adjustable hand grip rehabilitation training device. Background Technology

[0002] A hand grasping rehabilitation trainer is a rehabilitation device specifically designed to help patients improve hand function. It is mainly used for training and restoring hand grasping ability and is commonly used in rehabilitation treatment after stroke, traumatic brain injury, hand injury or other neuromuscular diseases.

[0003] Hand grip rehabilitation trainers typically consist of two handles and a spring. They utilize the spring's reaction force to train grip strength. The spring is usually directly attached to the connection between the two handles. Thus, when using two handles for hand grip training, the reaction force exerted by the two handles on the hand is constant. Different training stages require different grip strengths. Consequently, hand grip rehabilitation trainers with the same force are not convenient for adjusting their elasticity according to training needs. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides, for example Figure 1-4 The image shows an adjustable hand-grip rehabilitation training device.

[0017] Example 1 The device includes a connecting housing 1, a first grip 2, a second grip 3, an ear plate 4, a connecting block 5, a tension spring 6, and an adjustment assembly 7. The first grip 2 is fixedly connected to the bottom of the connecting housing 1, the second grip 3 is rotatably connected to one end of the connecting housing 1 via a hinge, the ear plate 4 is fixedly connected to the top of the second grip 3, the outer wall of the connecting block 5 is slidably connected to the connecting housing 1, and the tension spring 6 is hooked between the connecting block 5 and the ear plate 4. The tension spring 6 can exert a pulling force on the second grip 3 away from the rotation of the first grip 2 through the ear plate 4, so that the hand grips the first grip 2 and the second grip 3 together, thus performing hand grip strength training. The adjustment assembly 7 is set on the connecting housing 1 and is used to drive the connecting block 5 to slide on the connecting housing 1 to change the initial deformation of the tension spring 6, thereby changing the hand grip strength required when the first grip 2 and the second grip 3 are together.

[0018] In particular, the adjustment assembly 7 includes a drive block 71, an adjustment screw 72, a limit seat 73, and a fixing collar 74. The drive block 71 is slidably disposed inside the connecting housing 1. The bottom of the connecting block 5 is fixedly connected to the drive block 71, and the top of the connecting housing 1 has a sliding hole corresponding to the connecting block 5. The adjustment screw 72 is disposed inside the connecting housing 1, and the outer wall of the adjustment screw 72 is threadedly connected to the drive block 71. Thus, rotating the adjustment screw 72 can cause the drive block 71 to move the connecting block 5. The limit seat 73 is fixedly installed inside the connecting housing 1, and one end of the outer wall of the adjustment screw 72 is rotatably sleeved with the limit seat 73. The fixing collar 74 is sleeved on the outside of the adjustment screw 72 and is fixedly connected to the inside of the connecting housing 1. Under the action of the fixing collar 74 and the limit seat 73, the adjustment screw 72 can be stably rotated and installed inside the connecting housing 1.

[0019] Furthermore, the adjustment assembly 7 also includes a knob 75, a mounting collar 76, and a positioning rod 77. The knob 75 is located at the end of the adjustment screw 72. One side of the mounting collar 76 is fixedly connected to the knob 75. The mounting collar 76 is slidably sleeved on the end of the outer wall of the adjustment screw 72. The outer wall of the positioning rod 77 is slidably inserted into the mounting collar 76. The outer wall of the adjustment screw 72 has a through hole that matches the positioning rod 77. Under the action of the positioning rod 77, the knob 75 can drive the adjustment screw 72 to rotate through the mounting collar 76 and the positioning rod 77.

[0020] Furthermore, the adjustment assembly 7 also includes a first arc block 781, a second arc block 782, and a limiting assembly 79. The first arc blocks 781 are symmetrically installed at the ends of the connecting housing 1, and the two first arc blocks 781 are fixedly installed by fasteners and bolts. By removing the bolts and rotating the two first arc blocks 781, the joint of the two first arc blocks 781 is located on one side of the fastener, so that the two first arc blocks 781 can be separated and disassembled. The second arc block 782 is fixedly connected to one side of the first arc block 781, and the second arc block 782 is used to limit the positioning rod 77. By removing the first arc block 781 and the second arc block 782, the positioning rod 77 can be pulled out, thereby disassembling the knob 75. The limiting assembly 79 is set on one side of the first arc block 781, and the limiting assembly 79 is used to lock and limit the mounting collar 76.

[0021] Example 2 Based on Embodiment 1, the limiting component 79 includes a connecting plate 791, a hemispherical block 792, a limiting spring 794, a T-shaped member 793, and a guide rod 795. The connecting plate 791 is disposed on one side of the first arc block 781. The hemispherical block 792 is fixedly connected to the side of the connecting plate 791 facing the mounting collar 76. The outer wall of the mounting collar 76 has grooves in a ring array that match the hemispherical block 792. The limiting spring 794 is disposed on the side of the connecting plate 791 away from the hemispherical block 792. Under the action of the limiting spring 794, the hemispherical block 792 has a spring-like force that propels it toward the mounting collar 76. The force is applied to keep the hemispherical block 792 in corresponding engagement with the groove, thus ensuring the stability of the knob 75 when it is stationary. Rotating the knob 75 can separate the mounting collar 76 from the hemispherical block 792. The T-shaped piece 793 is fixedly connected to one side of the first arc block 781. One end of the guide rod 795 is fixedly connected to the connecting plate 791. The outer wall of the guide rod 795 is slidably sleeved with the limiting spring 794. One end of the guide rod 795 passes through the T-shaped piece 793 and is fixedly connected to the limiting block 796. The guide rod 795 can ensure the stability of the hemispherical block 792 when the connecting plate 791 drives it.
