[0033] Please refer to Figure 7 and Fig. 9 A first countersunk hole 942 is formed at the bottom end of the push rod 94, and a second countersunk hole 911 is formed on the bottom wall of the mounting shell 91. The two ends of the first compression spring 96 respectively conflict with the top wall of the first countersunk hole 942 and the bottom wall of the second countersunk hole 911; a first short shaft 941 is installed on the push rod 94, and a first long groove 951 and a second long groove 952 are respectively formed at the two ends of the rocker arm 95. The first short shaft 941 is slidably inserted into the first long groove 951. A second short shaft 973 is installed on the positioning rod 97, and the second short shaft 973 is slidably inserted into the second long groove 952.

[0034] In one embodiment, please refer to Figure 4 and Figure 8Two extension plates 972 are installed on the positioning rod 97 , and a second compression spring 98 is provided between the extension plate 972 and the cover 92 .

[0035] Specifically, a second countersunk hole 925 is opened on the cover 92, the upper end of the second compression spring 98 is in conflict with the top wall of the second countersunk hole 925, and the lower end is in conflict with the extension plate 972. By providing two second compression springs 98, the driving force is increased, thereby improving the reliability of the locking mechanism 9 when it is in a locked state.

[0036] In one embodiment, please refer to Figure 5 A C-shaped spring piece 99 is installed on the cover 92 , one end of the spring piece 99 is fixedly connected to the cover 92 , and the other end of the spring piece 99 is in contact with the bottom surface of the pressing plate 93 .

[0037] Specifically, the spring piece 99 is composed of a fixed section 991, a deformed section 992 and a supporting section 993 connected in sequence. A mounting groove 922 is provided on the top surface of the cover 92. The fixed section 991 is embedded in the mounting groove 922. Figure 6 A notch 9311 is provided at the bottom of the pressing plate 93, and the abutting section 993 abuts against the bottom wall of the notch 9311. The spring sheet 99 is elastic, and the pressing plate 93 is supported by the spring sheet 99. In addition, after the pressing plate 93 is pressed, the spring sheet 99 is reset, and the pressing plate 93 can also be driven to reset.

[0038] The pressure plate 93 is composed of a connected connecting rod 931 and a pressing portion 932. One end of the connecting rod 931 is rotatably connected to the support 923. A protrusion 933 is provided at the bottom of the pressing portion 932. The protrusion 933 abuts against the top surface of the push rod 94. The protrusion 933 is hemispherical.

[0039] In one embodiment, please refer to Figure 2 A pad 11 is pasted on the inner edge of the mask body 1.

[0040] After the medical staff puts the mask on the patient, they press the pressing portion 932 of the pressing plate 93, and the pressing plate 93 swings and presses the push rod 94 to move downward, and the first short shaft 941 drives the first long slot 951 to make the swing rod 95 swing clockwise (refer to Figure 4), and at the same time, the second long groove 952 of the swing rod 95 drives the second short shaft 973 to drive the positioning rod 97 to move upward (at this time, the first compression spring 96 and the second compression spring 98 are both compressed). Subsequently, the medical staff inserts the end 61 and the rack 84 into the movable hole 71, and makes the rack 84 mesh with the gear 83, and then operates the hand wheel 81 to rotate the gear 83 counterclockwise. The rotation of the gear 83 drives the rack 84 and the movable strap 6 to move, so that the length of the headband becomes smaller to a suitable length to fit the wearer's head. Then, the pressing part 932 is released, the spring piece 99 is reset, the first compression spring 96 and the second compression spring 98 are also reset, and at the same time, the positioning rod 97 is driven to move downward, and the locking head 971 is inserted into the corresponding tooth groove 841 to lock the position of the rack 84.

[0041] When the wearer feels that the headband is too tight or too loose against the head, the pressing portion 932 is pressed to move the positioning rod 97 upward and drive the locking head 971 out of the tooth groove 841. The hand wheel 81 is then operated to rotate the gear 83. The rotation of the gear 83 drives the rack 84 and the movable strap 6 to move to adjust the tightness between the headband and the wearer's head. After the adjustment, the pressing portion 932 is released, the positioning rod 97 is moved downward, and the locking head 971 is inserted into the corresponding tooth groove 841 to lock the position of the rack 84.

[0042] The present application can adjust the tightness of the headband, is easy to operate and adjust, and can meet the usage needs of different people, with good practicality.

[0043] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
