Technical Field

[0001] The utility model relates to the technical field of hand joint training, in particular to an intelligent hand joint training instrument telescopic device. Background Art

[0002] After hand bone and joint injury, half of the treatment depends on treatment, and the other half depends on functional training. The more you use the hand, the more flexible it becomes. Therefore, early functional training is very important for hand function recovery. The hand joint trainer is a commonly used device for recovery training of hand bones and joints.

[0003] At present, the hand joint training devices on the market are mainly electric and mechanical. Electric hand joint training devices require power supply, and the noise of the motor may affect the patient's experience. At the same time, they can usually only perform simple finger movement exercises, which leads to the fact that the functions of electric hand joint training devices are relatively simple; mechanical training devices are usually more complex in structure and require regular maintenance and care, which leads to increased costs. At the same time, they have poor adjustability and mobility, and are adjustable and large in size and heavy in weight, which is inconvenient for patients to carry and move, resulting in inconvenience for patients to train. Utility Model Content

[0004] In order to overcome the shortcomings of the existing hand joint training instruments that have relatively single functions and are inconvenient to use, the purpose of the utility model is to provide an intelligent hand joint training instrument telescopic device that has relatively comprehensive functions and is easy to use.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] Embodiment 1: A telescopic device for an intelligent hand joint training apparatus, such as Figure 1-Figure 3 As shown, it includes a base 1, a support plate 2, a movable plate 201, a limiting ring 202, an arm guard 3, a training glove 4, a movable part 5, an air bag 6, a driving mechanism, an auxiliary retraction and extension mechanism, an elastic rope 8, a pull rope 9, a pulley 10 and a wrist pneumatic mechanism. The upper part of the base 1 is connected to the support plate 2, the right part of the support plate 2 is rotatably connected to the movable plate 201, the upper right side of the movable plate 201 is connected to the limiting ring 202, the upper part of the support plate 2 is installed with an arm guard 3, the right side of the arm guard 3 is provided with a training glove 4, the training glove 4 is divided into a palm part and a five-finger part, the limiting ring 202 An airbag 6 is installed inside, and the airbag 6 contacts the palm part of the training glove 4. A movable part 5 is provided between the training glove 4 and the arm guard 3. A driving mechanism for inflating the airbag 6 is provided on the base 1, and an auxiliary retraction and expansion mechanism for grasping the fingers is provided on the limiting ring 202. A plurality of elastic ropes 8 are connected to the right part of the movable plate 201, and the elastic ropes 8 are all connected to the training glove 4 through the upper part of the limiting ring 202. A plurality of pull ropes 9 are also connected to the lower part of the training glove 4. A pulley 10 equal to the number of pull ropes 9 is provided above the movable plate 201, and a wrist pneumatic mechanism is provided on the movable plate 201.

[0019] like Figure 1-Figure 2 As shown, the driving mechanism includes an air pump 61 and a first air pipe 62 . The air pump 61 is installed on the right part of the base 1 , and the first air pipe 62 is connected between the air pump 61 and the airbag 6 .

[0020] like Figure 1-Figure 3 As shown, the auxiliary folding and unfolding mechanism includes a guide rail 71, a slider 72, a hinged rod 73, a connecting block 74 and a reset spring 75. The right part of the limiting ring 202 is connected to five guide rails 71, and the left part of the guide rails 71 is rotatably connected to the pulley 10, and the pulley 10 is in contact with the adjacent pull rope 9. The guide rails 71 are slidably connected to the slider 72, and the reset spring 75 is connected between the slider 72 and the right side of the guide rail 71. The five finger parts of the training glove 4 are connected to five connecting blocks 74, and the connecting blocks 74 and the adjacent guide rails 71 are rotatably connected with the hinged rod 73. The hinged rods 73 are all tilted to the right, so that the slider 72 can better pull the connecting block 74 and the five finger parts of the training glove 4 through the hinged rod 73, so that the fingers can bend better.

[0021] like Figure 2As shown, the wrist pneumatic mechanism includes a second air pipe 111, a telescopic piston cylinder 112 and an air intake pipe 113. Two telescopic piston cylinders 112 are installed on the right side of the support plate 2. The telescopic piston cylinder 112 includes a piston rod and a cylinder barrel. The second air pipe 111 is installed on the left side of the air pump 61. The air intake pipe 113 is connected between the second air pipe 111 and the right side of the telescopic piston cylinder 112.

[0022] First, put the palm that needs to perform joint training into the training glove 4 so that the fingers are inserted into the five finger parts of the training glove 4 accordingly, and control the air pump 61 so that the air pump 61 inflates the airbag 6 through the first air pipe 62. The inflation of the airbag 6 will squeeze the palm part of the training glove 4, so that the palm part of the training glove 4 moves upward. At this time, the connecting block 74 will pull the five finger parts of the training glove 4, so that the five finger parts of the training glove 4 move downward, thereby rotating the connecting block 74. At this time, the five finger parts of the training glove 4 will cause the human fingers to bend. During the upward movement of the palm part of the training glove 4, the elastic rope 8 will be deformed. At this time, the elastic rope 8 has a pulling force on the training glove 4, thereby preventing the position of the training glove 4 from shifting during the rising process.

[0023] When the palm part of the training glove 4 moves upward, it will pull the drawstring 9. Under the action of the pulley 10, the slider 72 will move toward the direction close to the limit ring 202. At this time, the reset spring 75 is stretched, and the slider 72 moves toward the direction close to the limit ring 202, which will pull the connecting block 74 through the hinge rod 73, and then pull the five-finger part of the training glove 4. Since the hinge rod 73 is tilted to the right, the slider 72 can better pull the connecting block 74 and the five-finger part of the training glove 4 through the hinge rod 73, so that the human fingers can be grasped through the five-finger part of the glove, so that the human hand joints can be better trained. The operation is simple and the noise is low, which facilitates the use of the device.

[0024] When the fingers need to be released, the air pump 61 is controlled to discharge the gas in the airbag 6 through the first air pipe 62. At this time, the airbag 6 contracts and no longer squeezes the training glove 4. The elastic rope 8 is restored, and the training glove 4 moves downward to return to its original position under the action of gravity. At the same time, the reset spring 75 is restored, so that the slider 72 moves away from the limit ring 202 to reset. The pull rope 9 also moves with the slider 72. The slider 72 no longer pulls the hinged rod 73, and the hinged rod 73 no longer pulls the connecting block 74 and the five-finger part of the training glove 4. At this time, the fingers in the training glove 4 are in a released state.

[0025] The air pump 61 is controlled so that the air pump 61 inflates the first air pipe 62 and the second air pipe 111 at the same time. The air in the second air pipe 111 then enters the cylinder of the telescopic piston cylinder 112 through the air inlet pipe 113. At this time, under the action of pressure, the telescopic piston rod will move in the direction close to the adjacent telescopic piston cylinder 112, so that the movable plate 201 rotates, and then the training glove 4 drives the human wrist to rotate upward, so that the finger joints can be trained while the wrist joints can be trained, thereby improving the hand joint training efficiency and increasing the training function of the device. When the air pump 61 is controlled to deflate the airbag 6, the second air pipe 111 and the air inlet pipe 113 can also release the gas in the telescopic piston cylinder 112. At this time, the movable plate 201 will reverse and return to its original position under the action of gravity, and the telescopic piston rod will also move to its original position.

[0026] Embodiment 2: Based on embodiment 1, Figure 1 As shown, a fixing belt 12 is also included, and the supporting plate 2 is provided with the fixing belt 12. The fixing belt 12 can fix the human arm, thereby preventing the arm from deflecting during the hand joint training process.

[0027] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
