The other end of the first rotating shaft 434 is rotatably connected to the inner wall of the movable groove 433. The baffle 436 is willow leaf shaped. Figure 4As shown, this structure is used to rotate the first rotating shaft 434 by rotating the adjusting ring 431, under the action of the meshing of the driving gear 432 and the movable groove 433, so that the internal baffle 436 rotates synchronously, adjusting the internal diameter of the first connecting hole 42, thereby fixing the air tube and improving the applicability of the device.
[0021] Furthermore, the locking assembly 44 includes a fixed plate 441, a second rotating shaft 442, and a movable plate 443. Two sets of fixed plates 441 are fixedly connected to the outer side of the positioning block 41. A second rotating shaft 442 is rotatably connected between the two sets of fixed plates 441. A movable plate 443 is fixedly connected to the outer surface of the second rotating shaft 442. A torsion spring 444 is movably sleeved on the outer surface of the second rotating shaft 442. One end of the torsion spring 444 is connected to the fixed plate 441, and the other end is connected to the movable plate 443. Figure 4 As shown, this structure is used to press one end of the movable plate 443, and under the action of the second rotating shaft 442 and the fixed plate 441 rotating connection, the other end of the movable plate 443 is disengaged from the surface of the adjusting ring 431. At the same time, the torsion spring 444 deforms, canceling the limit on the adjusting ring 431. After the adjusting ring 431 is adjusted, the end of the movable plate 443 is released. Under the elastic action of the torsion spring 444, the inner end of the torsion spring 444 is re-attached to the surface of the adjusting ring 431, preventing the movable plate 443 from rotating.
[0022] Furthermore, a second fixing rod 8 is fixedly connected to the bottom of each of the two sets of adjusting plates 3, and a Velcro 9 is movably fitted onto the outer surface of the second fixing rod 8. For example... Figure 2 As shown, this structure is used to attach Velcro 9 to the outside of the second fixing rod 8, which facilitates the fixing of other connecting pipes and improves the convenience of the device.
[0023] Furthermore, a protective pad 10 is fixedly connected to the inner wall of the support plate 1 and the adjusting plate 3. The protective pad 10 is made of silicone and has an arc-shaped surface. Ventilation holes 11 are provided inside the adjusting plate 3. Figure 2 As shown, this structure is used to protect the support plate 1 and the adjustment plate 3 from contact with the patient's body surface through the protective pad 10, so as to prevent scratches to the patient. The ventilation holes 11 enhance the breathability of the device and improve the patient's comfort.
[0024] Working principle: When using, such as Figure 1 As shown, the support plate 1 is attached to the patient's body surface via the straps 6, and then adjusted according to the patient's face, such as... Figure 2 As shown, by rotating the adjusting plate 3 using the movable rod 22, the inner wall of the adjusting plate 3 is brought into contact with the patient's body surface. After adjustment, the movable ring 24 is rotated to make the pad 25 fit against the surface of the adjusting plate 3, thus limiting the adjustment plate 3. Then, the fixing buckle 7 is pulled to fix the entire device. Figure 3 and Figure 4 As shown, pressing one end of the movable plate 443 causes the other end of the movable plate 443 to detach from the surface of the adjusting ring 431 under the action of the rotational connection between the second rotating shaft 442 and the fixed plate 441. At the same time, the torsion spring 444 deforms, releasing the limiting effect on the adjusting ring 431. Rotating the adjusting ring 431 causes the first rotating shaft 434 to rotate under the action of the meshing of the drive gear 432 and the movable groove 433, causing the internal baffle 436 to rotate synchronously, adjusting the internal diameter of the first connecting hole 42, thereby fixing the air tube. After adjusting the adjusting ring 431, the end of the movable plate 443 is released. Under the elastic action of the torsion spring 444, the inner end of the torsion spring 444 is reattached to the surface of the adjusting ring 431, preventing the movable plate 443 from rotating. The above is the complete working principle of this utility model.
