[0002] Lung function examination is one of the necessary examinations for respiratory diseases. By detecting the patency of the respiratory tract and the size of lung capacity, the condition of the lungs and respiratory tract can be judged, so as to prescribe the right medicine. For patients with respiratory tract problems during the rehabilitation process, a breathing trainer is used to exercise lung function, and blowing can effectively relieve symptoms such as asthma and cough of the patients.

[0003] At present, when the existing breathing trainer is in use, it usually uses a nozzle to connect to an air pipe, and the connection between the nozzle and the air pipe is only by means of plugging. When the user trains frequently, it is easy to cause the air pipe to fall off and air leakage during use, thus affecting the normal training of the user. For this reason, we propose a blowing training device to solve the above problems. Content of the Utility Model

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Referring to Figures 1-5 , a blowing training device includes a training air cylinder 1. A nozzle 2 is connected to the side of the training air cylinder 1, and an air pipe 3 is sleeved outside the nozzle 2. The training principle of the training air cylinder 1 is the prior art and will not be elaborated here. Support plates 4 are distributed on the side wall of the training air cylinder 1, and a threaded rod 5 is connected to the inside of the support plate 4 through a bearing. Two moving plates 6 are sleeved outside the threaded rod 5, and clamping plates 7 are provided on the sides of the moving plates 6. Rotating rods 9 are equidistantly connected to the top of the threaded rod 5. Opposite external threads in two opposite directions are symmetrically provided at the upper and lower ends of the threaded rod 5 (not shown in the figure). Thread grooves adapted to the external threads are respectively provided inside the two moving plates 6. Therefore, when the threaded rod 5 rotates, the two moving plates 6 can be driven to move towards each other. Through the connection of the rotating rods 9, it is convenient for the user to quickly rotate the threaded rod 5.

[0024] Furthermore, referring to Figure 3 and Figure 4 , it can be known that the clamping plate 7 is set as an arc structure, and rubber strips 8 are evenly distributed on the inner wall of the clamping plate 7. Through the arc-structured clamping plate 7 and the connection of multiple groups of rubber strips 8, the clamping effect on the air pipe 3 can be improved.

[0025] Furthermore, referring to Figure 3 , it can be known that a guiding rod 10 is vertically connected to the inner wall of the threaded rod 5, and a moving groove adapted to the guiding rod 10 is provided inside the moving plate 6. Through the connection of the guiding rod 10, the guiding of the moving plate 6 can be realized, effectively preventing the moving plate 6 from rotating simultaneously with the threaded rod 5, so as to ensure the smooth up and down movement of the two moving plates 6.

[0026] Furthermore, referring to Figure 2 and Figure 4 , it can be known that an anti-slip ring 12 is connected to the side of the support plate 4, and the anti-slip ring 12 is connected to the training air cylinder 1 through bolts. Through the mutual cooperation of the anti-slip ring 12 and the bolts, the disassembly and installation between the training air cylinder 1 and the support plate 4 can be realized. When the threaded rod 5 has faults such as slipping threads after long-term use, maintenance personnel can separate the anti-slip ring 12 from the training air cylinder 1 and replace it, without discarding the entire device.

[0027] Furthermore, referring to Figure 3 and Figure 4 , it can be known that positioning rods 11 are respectively connected to the sides of the clamping plates 7 close to each other, and a clamping groove adapted to the positioning rods 11 is provided inside the air pipe 3. Through the mutual cooperation of the clamping plates 7 and the clamping grooves, the limiting effect on the air pipe 3 can be improved.

[0028] Furthermore, referring to Figure 3 and Figure 4It can be known that the outer surface of the positioning rod 11 is equidistantly sleeved with anti-slip rings 12, and the outer diameter of the anti-slip ring 12 is matched with the inner diameter of the slot. By using multiple groups of anti-slip rings 12 made of rubber material, the tightness of the anti-slip ring 12 in the slot can be effectively guaranteed, thereby further improving the tightness of the ventilation pipe 3 and the air nozzle 2 during the connection process.

[0029] Further, see Figure 3 , Figure 4 and Figure 5 It can be known that a docking groove 13 compatible with the movable plate 6 is provided inside the splint 7, an insertion rod 14 is inserted into the outer wall of the splint 7, a positioning groove compatible with the insertion rod 14 is provided inside the movable plate 6, and the end of the insertion rod 14 is connected to a rotating block 15. Through the mutual cooperation of the docking groove 13 and the insertion rod 14, the disassembly and assembly operation between the movable plate 6 and the splint 7 can be realized. When the splint 7 needs to be replaced, it is only necessary to pull the rotating block 15 to pull the insertion rod 14 out from the inside of the movable plate 6 and the splint 7 to release the limit on the splint 7, thereby facilitating the user to quickly replace the damaged splint 7.

[0030] When the user presses the lever 9 together, the two guide rails 7 are in a closed position, and the two guide rails 7 are in a closed position, so that the user can easily move the two guide rails 7 together, and then the user can turn the lever 9 to move the two guide rails 7 together, so that the two guide rails 7 can move in a closed position.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
