Description

Technical Field

[0001] The utility model relates to the field of wrist joint training, in particular to a wrist joint rotation training device. Background Art

[0002] In the past, wrist rotation training often required patients to hold the handle of the training device and perform active wrist rotation movements in a circular trajectory. In actual use, this type of training device, on the one hand, requires a high grip strength of the patient. Patients with poor grip strength cannot hold the handle and cannot train the wrist joint. On the other hand, it is inconvenient for patients to operate, because after holding the handle, as the hand rotates, for example, from the left to the right, it is necessary to loosen the handle, adjust the direction of the palm and back of the hand, and then hold the handle again to complete a complete rotation. Therefore, how to reduce the grip strength requirements of the patient during wrist rotation training and avoid repeated loosening and adjusting the direction are problems that technicians in this field urgently need to solve. Utility Model Content

[0003] The purpose of the present invention is to provide a wrist joint rotation training device to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wrist joint rotation trainer comprising a supporting base plate, an upward-facing support plate fixed to the rear end of the base plate, and a connecting rod rotatably connected to the support plate, capable of clockwise or counterclockwise rotation. The end of the connecting rod is equipped with a latching mechanism that facilitates clockwise or counterclockwise rotation and angle adjustment after hand insertion. Compared to wrist exercises on the market, the latching mechanism here not only allows the connecting rod to rotate around the support plate but also allows it to rotate on its own, which has the advantage of preventing the wrist from being twisted. Furthermore, the palm of the hand can be inserted into the trainer, requiring less grip strength.

[0005] Preferably, the holding mechanism includes a support ring mounted at the end of the connecting rod, and a guide cavity with a C-shaped cross-section opening toward the center is provided within the support ring. Furthermore, the support ring further includes a rotating mechanism disposed within the support ring. After grasping the rotating mechanism, the hand can rotate and twist around the support ring, thereby driving the connecting rod to rotate around the support plate for exercise. The rotating mechanism can rotate around the support ring, thereby allowing the wrist to be twisted to a desired angle, providing greater comfort and facilitating exercise.

[0006] Preferably, the rotating mechanism includes a horizontal plate installed in the support ring along the radial direction, with both ends of the horizontal plate inserted into the guide cavity of the support ring, and the horizontal plate is provided with a strip-shaped slot for inserting the palm. The slot is convenient for four fingers to pass through and can be set in grooves corresponding to the four fingers.

[0007] Preferably, arc-shaped guide rods are provided at both ends of the transverse plate and are inserted into the guide cavity. The guide rods are bent along the guide cavity.

[0008] Preferably, the device further comprises a telescopic mechanism arranged between the connecting rod and the supporting ring. During the rotation process, the position of the hand changes, and the telescopic mechanism makes the hand more comfortable.

[0009] Preferably, the telescopic mechanism includes a telescopic plate sleeved on one end of the connecting rod away from the support plate, and the other end of the telescopic plate is fixed to the support ring. The cross section of the connecting rod is square or circular. If it is circular, it can rotate and change the angle of the hand, while the square one will not.

[0010] Preferably, the end of the support plate is connected to the bottom of the inner cavity of the telescopic plate by a rubber strip, which can also be a spring to prevent the telescopic plate from slipping.

[0011] Preferably, the bottom plate is provided with an airbag cushion for convenient placement of the elbow joint, making it more comfortable for the elbow joint and the arm to be placed thereon. At the same time, in order to be more flexible, the middle part of the airbag cushion can be fixed while the periphery is not fixed, so that the twisting angle can be larger and more comfortable.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Put four fingers through the slots and you can buckle them or lightly grasp them. Place your elbow on the airbag cushion and then rotate your hand. This way, the connecting rod rotates around the support plate to achieve a circular motion, while the horizontal plate can rotate around the support ring. This way, the hand can twist and rotate around itself to change the angle, which is more comfortable and more conducive to exercise.

[0014] 2. The telescopic plate is telescopic on the connecting rod, so it is convenient to change the distance during exercise;

[0015] 3. Compared with traditional methods, patients do not need to hold the handle, and the grip strength requirement is not high. As long as the hand is inserted and can be hooked, it will be fine. BRIEF DESCRIPTION OF THE DRAWINGS
