[0002] With the improvement of industrial level, there are many patients with wrist joint injuries in clinical practice. After the trauma, they have different degrees of wrist dysfunction. After rehabilitation treatment, the function can be significantly improved. Patients can train the proprioception of the wrist joint through wrist exercisers, including hand grip strength training, wrist joint flexibility training, and wrist joint control ability training, thereby improving the function of the wrist joint.

[0003] At present, common wrist exercisers are usually designed with springs or elastic bands, and their resistance can be adjusted to meet the needs of various exercise forces. However, there are also some shortcomings. For example, when the existing wrist exercisers use springs or elastic bands, the direction of their resistance is limited by the freedom of mechanical components, the direction is relatively single, not flexible enough, and the exercise process is boring. The wrist is a relatively flexible joint, and more comprehensive exercise is required during rehabilitation exercise. Therefore, the utility model proposes a wrist exerciser with higher flexibility and more fun. Utility Model Content

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0025] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Reference Figure 1 and Figure 2 As shown, a wrist exerciser includes a tray 1, a moving track 11 is provided on the tray 1, a counterweight assembly 3 is provided on the moving track 11, and the counterweight assembly 3 is detachably installed on the moving track 11. When exercising the wrist, the counterweight assembly 3 slides along the moving track 11 by controlling the force size and force direction of the wrist; a gripping handle 2 is connected to the tray 1.

[0027] Among them, the trajectory of the motion track 11 is an arc spiral. When the counterweight assembly 3 slides on the spiral motion track 11, its sliding path is continuous, and its torque change is also continuous, which is more suitable for patients who have just used the wrist exerciser. The trajectory of the motion track 11 can also adopt a square spiral. There are many corners on its square spiral. When exerting force, it is more necessary to pay attention to the change of force direction. The shape of the motion track 11 includes but is not limited to the two shapes mentioned in the utility model. When different trajectories are used, when exercising the wrist, the direction of wrist force and the frequency of rotation are different, and the effect of wrist exercise will also be different.

[0028] Sliding grooves 111 are provided on both sides of the motion track 11. The counterweight assembly 3 includes a connecting seat 32 and a gravity ball 31. The connecting seat 32 is provided in the sliding groove 111. The connecting seat 32 will not fall out of the motion track 11 when inserted into the sliding groove 111. The gravity ball 31 is rotatably connected to the connecting seat 32. The gravity ball 31 can be rotated when in use. When the gravity ball 31 rotates, it will obtain a rotational inertia. When the gravity ball 31 encounters a torque during rotation, trying to deflect its rotation axis, then according to the law of conservation of angular momentum, the rotor will generate a torque in the opposite direction. This torque will be fed back to the wrist through the tray 1 and the gripping handle 2, thereby providing a resistance in the opposite direction of the wrist rotation. The gravity ball 31 has multiple specifications such as 0.5kg, 1kg, 2kg and 3kg, which can provide options for patients with different hand dysfunctions.

[0029] A disassembly portion 12 is provided at one end of the moving track 11. When the counterweight assembly 3 is to be replaced, the counterweight assembly 3 is moved to the disassembly portion 12 and removed. The opening of the disassembly portion 12 is larger than the diameter of the connecting seat 32. The tray 1 is also provided with a slider 13. One end of the slider 13 can be retractably inserted into the moving track 11. When the slider 13 extends into the moving track 11, the connecting seat 32 is prevented from entering the disassembly portion 12, which can prevent the counterweight assembly 3 from falling off when wrist exercises are performed.

[0030] A mounting portion 14 is formed on one side of the tray 1, and the mounting portion 14 includes a circular track. The gripping handle 2 slides in the circular track. A nut is also provided on the gripping handle. By adjusting the tightness of the nut, the gripping handle and the mounting portion 14 can be switched between a sliding state and a fixed state. In the sliding state, the gripping handle slides in the circular track. When in use, there will be an uncertain force provided between the gripping handle 2 and the tray 1, making it more difficult to control the counterweight assembly 3, testing the patient's wrist control ability.

[0031] The gripping handle 2 uses an air bag, which can provide more proprioceptive input for the patient's hand and fit the patient's palm more closely. An adjustable valve 21 is provided on the air bag. By switching the adjustable valve 21, the gas content in the air bag can be adjusted to change the hardness of the air bag, and the hand gripping strength training can also be provided.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
