Description

Technical Field

[0001] The utility model relates to the technical field of protective masks, in particular to a protective mask with adjustable straps. Background Art

[0002] A protective mask is a device used to protect the respiratory tract from airborne particles such as particulate matter, bacteria or viruses. Common masks include medical masks and dust masks. Medical masks are generally used in medical environments, while dust masks are used in industrial, construction and general environments.

[0003] Some people who use protective masks need to wear glasses while wearing masks due to vision problems, while some people have a collapsed nose bridge, which makes it difficult to keep glasses fixed and they are easy to slip off. In addition, since the surface of the mask is relatively smooth and covers the bridge of the nose, it is easier for the glasses to fall off while wearing the mask. In addition, when wearing a mask in cold weather, when the wearer exhales, the hot air can easily contact the glasses lenses through the gap between the top side of the mask and the face and the skin, causing the lenses to fog up and affecting the field of vision. Utility Model Content

[0004] The technical problems to be solved by the utility model are as follows: since the surface of the mask is relatively smooth and covers the bridge of the nose, it is easier for glasses on the surface to fall off when the mask is worn; when the wearer exhales, hot air easily contacts the glasses lenses through the gap between the top side of the mask and the skin of the face, thereby causing the lenses to fog.

Figure 1 and Figure 3 As shown, the anti-skid pad 106 is made of rubber material, which can increase the friction between the top support 105 and the eyeglass frame;

[0031] A baffle 109 is fixedly connected to the top of the back side of the main body 101. Figure 2 As shown, the baffle 109 is made of silicone. When the mask 1 is worn, the baffle 109 fills the gap between the wearer's face and the main body 101 and blocks the hot air exhaled by the wearer;

[0032] The outer wall of the main body 101 is fixedly connected to the elastic parts 107 on both sides, and the other sides of the two elastic parts 107 are fixedly connected to the connecting parts 110. Figure 2 As shown, the elastic portion 107 may be a rubber band or other elastic material;

[0033] The outer wall of the connecting portion 110 and the upper and lower ends thereof which are located away from the elastic portion 107 are fixedly connected with a drawstring 108, and the connecting portions 110 on both sides are connected to each other through two drawstrings 108. Figure 1 As shown, when the mask is worn, the drawstring 108 is bound to the wearer's head;

[0034] The adjustment mechanism 2 includes a connecting sleeve 201, a sliding groove 202 is provided on the middle inner wall of the connecting sleeve 201, and the inner lower end of the sliding groove 202 is symmetrically fixedly connected to the limit axis 203. A through hole 204 is provided on the middle inner wall of the connecting sleeve 201 and above the limit axis 203. The inner wall of the through hole 204 is connected to the strap rope 108 through and through. Figure 1 As shown, by adjusting the position of the connecting sleeve 201 on the drawstring 108, the wearable length of the drawstring 108 can be adjusted;

[0035] The inner wall of the slide groove 202 is slidably connected with a pressure rod 205, and the pressure rod 205 is T-shaped. The outer wall of the pressure rod 205 and one end located inside the slide groove 202 is fixedly connected with an extrusion ring 206. The bottom of the extrusion ring 206 is fixedly connected with a spring 207. The bottom end of the spring 207 is fixedly connected to the inner wall of the slide groove 202.

[0037] The working principle of this utility model:

[0038] When adjusting the length of the strap rope 108, press the pressure rod 205 downward. At this time, the squeezing ring 206 squeezes the spring 207 downward, the spring 207 contracts, and the pressure rod 205 drives the fixing part 208 to descend in the slide groove 202, so that the fixing part 208 is separated from the strap rope 108 in the through-hole 204. At this time, the strap rope 108 can be pulled to change the wearing length of the strap rope 108. After adjusting the outer wall, release the pressure rod 205, the spring 207 releases the elastic potential energy to lift the squeezing ring 206, and the pressure rod 205 lifts the fixing part 208. The fixing part 208 squeezes the strap rope 108 in the through-hole 204 and clamps the strap rope 108 in the through-hole 204.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
