[0016] The beneficial effects of the present invention are:

[0017] (1) The respiratory training device for respiratory rehabilitation described in the present invention has a training structure on the fixing seat, a locking structure on the training structure, and a limiting structure on the locking structure. The training structure allows the patient to perform respiratory training and exercise the patient's respiratory muscles. The locking structure can fix the hose to prevent the hose from becoming larger in diameter after repeated use, resulting in loose connections and air leakage. The limiting structure can limit the locking assembly when no respiratory training is performed, so that the hose can be fixed by the locking assembly during training. That is, when respiratory training is required, the hose and the inhalation tube can be connected and fixed by a rubber block. The hose can be limited and damage to the hose can be avoided during docking. When the hose is plugged into the suction pipe, one end of the locking belt is pulled to pass the other end of the locking belt through the rubber block. At this time, the card block on the locking belt can enter the rubber block and conflict with the resistance block, so that the resistance block compresses the first spring piece. When the locking belt is continuously pulled, the resistance block can conflict with different card blocks. When the locking belt is tightened, the locking belt is released, and the resistance block can be reset by the elastic force of the first spring piece and conflict with the right-angled side of the card block to fix the locking belt and prevent the locking belt from loosening. Then, one end of the locking belt can be inserted into the fixing groove on the fixing block to put the excess locking belt in. The hose and the inhalation tube can be fixed with a locking belt, and air leakage can be avoided with a rubber ring. Repeated plugging and use will prevent the diameter of one end of the hose from becoming larger, causing air leakage at the connection. After the hose is fixed, plug the mouthpiece and the other end of the hose. During breathing training, the patient can hold the fixing seat, maintain normal breathing, put the mouthpiece in the mouth, inhale slowly and evenly to make the piston ball in the gas tank rise to the marked position on the gas tank, maintain inhalation for 2 to 3 seconds, then release the mouthpiece, exhale slowly, adjust breathing and then train again. After the training, the mouthpiece can be removed from the hose and the rubber ring can be pulled. The pull block on the block drives the pull rope to move, changes the direction of force through the pulley, and applies upward force to the resistance block, so that the resistance block compresses the first spring sheet. At this time, the locking belt can be taken out of the rubber block, and the hose is no longer fixed. The hose and the suction pipe are separated, and then the locking belt is clamped in the limiting groove on the rubber block, and the locking belt is fixed by the protrusion and groove, and one end of the locking belt is inserted into the fixing groove on the fixing block to fix the locking belt to prevent the locking belt from scattering outside. After cleaning the hose and the mouthpiece, one end of the hose and the mouthpiece can be plugged and placed in the fixing frame, and the other end of the hose can be clamped in the bracket to fix the hose.

[0018] (2) The respiratory training device for respiratory rehabilitation described in the present invention has a rotating structure on the training structure, a transmission structure on the fixed seat, and a fixed structure on the rotating structure; different identification images can be adjusted by the rotating structure to enhance the interest of training and enhance the initiative of patient training; multiple identification images can be adjusted simultaneously by the transmission structure; the position of the identification image can be kept fixed after adjustment by the fixed structure to avoid the rotation of the identification plate during patient training and affect the patient's training, that is: during inhalation training, the piston ball can be controlled to suspend at different positions in the gas tank by inhalation, and the patient controls the piston ball to be at three targets on the gas tank one by one. After completing the training task, the plug block can be pressed so that the plug block is no longer engaged with the slot, and the second spring sheet can be compressed and retracted into the slider, and the slider can be slid to release the plug block. At this time, the sliding slider can drive the bar rack to slide in the fixed seat, and the bar rack and the first gear are meshed to drive the fixed shaft fixed to the first gear to rotate, and then the transparent identification plate in the gas tank can be driven to rotate by the cross bar and the connecting rod. When the identification plates with different identification images are located at the three targets on the gas cylinder, the elastic force of the second spring piece can make the plug block and the second slot in the fixing seat engage, fix the slider, and then fix the identification plate, so as to prevent the identification plate from rotating during patient training and affecting the patient's control of the piston ball to stay at different identification plate positions. When the patient completes the training task again, the plug block can be continued to be pressed. When the plug block is no longer engaged with the slot, the slider is slid and released, and the identification plate is driven to rotate again by sliding the slider. When the identification image on the identification plate is changed again, the elastic force of the second spring piece can make the plug block and the third slot in the fixing seat engage, fix the identification plate, and enable the patient to control the piston ball to continue breathing training, thereby enhancing the fun of training and improving the patient's interest in training. When the patient pushes the slider to change the identification image, since the second gears are fixedly connected to the three fixed shafts, and the three second gears are meshed through the rack ring, when one of the fixed shafts rotates, the other two fixed shafts can be driven to rotate, and the identification plates on the three gas cylinders can be adjusted at the same time.
