A pair of slits 20 are respectively introduced by the curved surface 10 and arranged obliquely, and the angle between the valley portion 13 and the slit 20 is greater than or equal to the angle between the slit 20 and the peak portion 11, wherein equal to 90 degrees, greater than So it means between 90 degrees and 135 degrees. Preferably, the pair of slits 20 are respectively introduced by the valley portion 13, and the distance between the upper and lower pair of slits 20 is between 20 mm and 50 mm, and the distance between the left and right pair of slits 20 is between Between 20mm and 65mm.

When using the fixed sheet 1 of the utility model mask strap, as shown in Figure 2, first pick up the mask, the mask side strap 2 is attached to one of the pair of slits 20 of the utility model fixed sheet 1, and then Put on the mask, pull the unfixed lanyard 2 to the back of the head, and place it on the valley 13 first, then the lanyard 2 can automatically slide along the curved surface 10 and easily slide into another pair of slits 20 to fix it, and adjust the bridge of the nose Then stretch the mask so that it completely covers the mouth, nose and chin, and the whole wearing process is completed.

The wearing method is changed from ear hanging to head hanging, so it can avoid the discomfort of wearing the ear for a long time, making it comfortable to wear and more suitable for long-term wearing. Constrict or snug around the ear.

The design of the peaks 11 and valleys 13 connected by the curved surface 10 above makes the strap 2 automatically slide along the curved surface 10 and easily slide into the slit 20 (or groove 30 ) after being placed on the valley 13 for rapid positioning. And it is easier, convenient and time-saving to attach and hang.

In addition, through the technology that the slit 20 is arranged obliquely and the angle between the valley portion 13 and the slit 20 is greater than or equal to the angle between the slit 20 and the peak portion 11, the force direction of the lanyard 2 after hanging is facing away from The notch of the slit 20 is oriented so that when the position is properly pulled and adjusted, the fixing effect of the hanging strap 2 is better.

In addition, during the attaching process, two pairs of slits 20 with an appropriate distance (within the range of 20 mm to 65 mm) are used to fix the strap 2 after it is attached. There are several types of head shapes designed and developed for the general public. Style, in order to meet the needs of better elastic.

Please refer to shown in Fig. 3, it is the second structural representation of the fixed piece 1 of the utility model mouth mask hanging strap, and it is mainly the same as the previous disclosed embodiment, and its difference is that:

A pair of slits 30 are adjacent to the pair of slits 20, and the pair of slits 30 are respectively introduced by the peaks 11 and arranged obliquely, and the angle between the peaks 11 and the slits 30 is smaller than that between the slits 30 and the valleys. 13, wherein less than means between 0 degrees and 45 degrees. In addition, the pair of slots 30 can also be introduced from between the peaks 11 and the valleys 13 (not shown) and be inclined, and the angle between the valleys 13 and the slots 30 is greater than or equal to that of the slots. The angle between 30 and peak 11.

An opening 40 can be approximately elliptical, and is formed between the pair of slits 20 through the fixing sheet 1 .

To attach the lanyard 2 to the fixed piece 1, as shown in Figure 4, the lanyard 2 on one side of the mask can be attached to the pair of slits 20, and finally another lanyard 2 can be attached here On the cutting groove 30, the head hanging and the whole wearing process are completed.
