The length of the cord is adjusted so that the length of the cord can be adjusted. Hereinafter, for convenience of description and illustration, the case where the coupling is attached to the coupling hole 210 of the mask base frame 200 will be described.

The mask strap length adjustment module 300 includes a body 310, the coupling protrusion 320, the opening 330 and the length adjusting portion 340.

First, the body 310 has a shape through which the inside of the mask string 400 can be penetrated. Specifically, the through hole 350 is formed along the length direction.

The coupling protrusion 320 protrudes from one side of the body 310 and is detachably coupled to the coupling hole 210 of the mask base frame 200. In the related drawings, a case in which a total of four coupling holes 210 and coupling protrusions 320 are provided is illustrated, but the number may be increased or decreased as necessary.

Next, the opening 330 is provided at one side of the body 310 to form a passage so that the mask string 400 inserted into the body 310 is exposed again to the outside. Referring to the method of combining the strings, the user inserts the mask string into the through hole 350 while unwinding both ends of the mask string 400 and withdraws both ends of the mask string to the outside of the body 310 through the opening 330. After moving both ends to the length adjustment unit 340, which will be described later to be used by binding both ends of the string. Here, the width or length of the opening 330 is preferably formed to be larger than a predetermined thickness than the thickness of the mask strap 400.

Next, the length adjusting part 340 is provided to communicate with the opening 330 on both sides of the opening 330, and is provided to enable the length adjustment by the user's force control by pressing the mask strap 400 more than a predetermined amount.

In one embodiment of the present invention, as shown in FIG. 5, the length adjusting part 340 communicates with the opening 330, but has a communication path 341 having a narrow passage area compared to the opening 330. And a pressure fixing hole 342 provided at an end thereof so as to communicate with the communication path 341.

Here, it is preferable that the communication path 341 is formed in a straight shape, and the passage area (cross-sectional area in the direction perpendicular to the length direction) is formed to be smaller than a certain thickness than the thickness of the usual mask string 400 to which no external force is applied. . Therefore, when the user withdraws the mask string 400 at both ends to the opening 330 and moves the mask string 400 to the pressure fixing hole 342 side along the communication path 341, the mask string 400 is moved in a sufficiently pressurized state. The length adjustment of the adjusted mask strap 400 can be fixed first. In other words, the user may adjust the overall string length by changing a portion of the mask string 400 drawn out through the opening 330 and entering the communication path 341. The communication path 341 may be provided to gradually reduce the cross-sectional area from the opening 330 toward the pressure fixing hole 342, and thus may firmly fix a specific portion of the mask strap 400.

The pressure fixing hole 342 is provided at the end of the communication path 341 so as to communicate with the communication path 341, and is fixed by pressing the mask string 400 moved to the inside of the predetermined or more times. The communication path 341 preferably has a shape corresponding to the cross-sectional area of the mask string 400, and the cross-sectional area of the mask string 400 in which no external force acts to press and fix the mask string 400 is fixed or more. It is preferable that it is formed smaller than a certain thickness than).

In another embodiment, as shown in FIG. 7, the communication path 341 may be formed in a zigzag shape without being formed in a straight line shape. In this case, the inside of the pressing fixing hole 342 is moved by the inner surface of the pressing fixing hole 342 and the string portion fixed to enter the communication path 341 side, so that the desired length control of the mask string cannot be changed or changed. The occurrence of the phenomenon is further prevented. In addition, although the communication path 341 has a passage area smaller than the thickness of the string, when the communication path 341 is formed in a straight line, the part of the string entering the communication path 341 is connected to the communication path 341 by external force. A problem of moving toward the opening 330 along the side may occur.

In the present invention, by stably restricting the movement of the string portion entering the communication path 341 toward the opening 330 through the zigzag shape of the communication path 341, the mask string length is stably adjusted and the adjusted state is controlled. Will be maintained. The number of zigzag may be provided at least once.

In another embodiment of the present invention, as shown in Figure 8 and 9, the inner surface of the pressure fixing hole 342 may be additionally provided with a plurality of pressing projections 343 for pressing the mask string 400. have. In addition, the communication path 341 is provided to gradually reduce the cross-sectional area toward the pressure fixing hole 342 side.

The pressing protrusions 343 may be provided in plural to be spaced apart along the inner circumferential direction of the pressing fixing hole 342 and may be provided in plural to be spaced apart from each other along the thickness direction of the pressing fixing hole 342. have.

The pressing protrusion 343 may further press the corresponding portion of the mask string 400 guided into the pressing fixing hole 342 and thus more stably maintains a state in which the length of the string is adjusted as a whole.
