Description

Improved protective mask

This creation is about an improved protective mask, especially one that allows the headband adjustment mechanism to be less prone to looseness, comfort, and ease of disassembly.

According to the conventional protective mask, a mask is formed, a mask disposed on the end surface of the brim, and an elastic band disposed on both sides of the brim; thereby allowing the user to wear the elastic band on the head with the brim and the elastic band. The mask is used for face protection.

However, in the case of the above-mentioned protective mask, the elastic band cannot be adjusted according to the shape of each user's head when wearing, and therefore, different users often produce too loose or too tight when wearing. Occurs, resulting in a greatly reduced comfort when wearing, and after a period of use, the elastic band often leads to elastic fatigue due to constant pulling, so that the elastic band is loose and cannot be provided by the user; Moreover, since the elastic band cannot be removed from the cap, the user cannot continue to use the protective mask when the above-mentioned condition occurs during use.

The main purpose of this creation is to avoid the persistence of the above-mentioned formula, so that the adjustment of the appropriate tightness can be performed by using the adjustment unit and the fastening unit provided by the headband adjustment mechanism during the wearing to make the headband The adjustment mechanism conforms to the head shape of the user, and in addition, It is necessary to remove the headband adjusting mechanism on the brim for replacement, thereby making the headband adjusting mechanism less prone to looseness, comfortable, and easy to disassemble and replace.

To achieve the above objective, the present invention relates to an improved protective mask comprising: a brim; a headband adjustment mechanism coupled to the brim activity, comprising an adjustment unit disposed on one side of the brim and an active engagement with the adjustment unit And a fastening unit disposed on the other side of the brim; and a mask disposed on an end surface of the brim.

In an embodiment of the present invention, the brim is curved, and the two sides of the brim are respectively provided with a limiting hole combined with the movement of the headband adjusting mechanism, and respectively located at positions adjacent to the limiting holes respectively. A coupling hole is provided for combining with the mask movement.

In an embodiment of the present invention, the adjusting unit comprises a belt body, a rack portion disposed on at least one side of the belt body, and a movable end portion disposed on one end of the belt body and engaging with the limiting hole provided on one side of the brim body. The pivot axis.

In an embodiment of the present invention, the fastening unit includes a belt body, a sleeve portion disposed on the belt body, a buckle member disposed on the belt body and corresponding to the sleeve portion, and a belt disposed on the belt A pivoting shaft at one end of the body and movably coupled to the limiting hole provided on the other side of the brim.

In an embodiment of the present invention, the mask is curved, and the two sides of one end of the mask are respectively provided with perforations corresponding to the respective coupling holes, and each of the perforations of the mask is respectively a tip piece and a Binding to the pores for active binding.

Please refer to the "1st, 2nd, 3rd, and 4th drawings" for the three-dimensional appearance of the creation, the three-dimensional exploded view of the creation, the three-dimensional appearance of the other angle of the creation, and the adjustment state of the creation. . As shown in the figure, an improved protective mask is constructed, which is composed of at least one brim 1, a headband adjusting mechanism 2 and a side cover 3.

The cap 1 is curved in a curved shape, and the two sides of the cap 1 are respectively provided with a limiting hole 11 and 11a, and a coupling hole 12 is respectively disposed at a position adjacent to each of the limiting holes 11, 11a. 12a.

The headband adjusting mechanism 2 is movably coupled to the brim 1 and includes an adjusting unit 21 disposed on one side of the brim 1 and a fastening unit 22 movably engaged with the adjusting unit 21 and disposed on the other side of the brim 1 . The adjusting unit 21 includes a belt body 211, a rack portion 212 disposed on at least one side of the belt body 211, and a pivoting member disposed at one end of the belt body 211 and movably coupled with the limiting hole 11 provided on the side of the brim 1 The fastening unit 22 includes a belt body 221, a sleeve portion 222 disposed on the belt body 221, a buckle 223 disposed on the belt body 221 and corresponding to the sleeve portion 222, and a buckle The pivot shaft 224 is disposed at one end of the belt body 221 and is movably coupled to the limiting hole 11a provided on the other side of the cap 1 .

The mask 3 is disposed on one end surface of the brim 1 , and the mask 3 is curved, and the two sides of the mask 3 are respectively provided with perforations 31 , 31 a corresponding to the respective coupling holes 12 , 12 a , and Each of the perforations 31, 31a of the mask 3 is movably coupled to each of the coupling holes 12, 12a by a tip member 32, 32a. If so, combine the above technical features into a change Good protection mask.

When the user wears, the adjustment unit 21 and the fastening unit 22 of the headband adjustment mechanism 2 respectively correspond to the two sides of the head, and the belt 211 of the adjustment unit 21 is disposed through the fastening unit 22 The sleeve portion 222 is inserted into the sleeve portion 222, and the belt body 211 is pulled to move in the sleeve portion 222. When the position to conform to the shape of the user's head is pulled, the belt body 211 is stopped, and the rack portion 212 and the buckle of the adjustment unit 21 are buckled. The buckle 223 of the connecting unit 22 is formed into a buckle, so that the adjusting unit 21 and the belt body 211, 221 of the fastening unit 22 cooperate with the cap 1 to form a ring shape, so that the headband adjusting mechanism 2 on the brim 1 is properly tightened. It is worn on the user's head and is not easy to loosen and has better comfort.

When the user wants to take off the protective mask or re-adjust the elasticity of the headband adjusting mechanism 2, the two sides of the wearing portion 222 are directly pressed, and the rack portion 212 of the adjusting unit 21 and the fastening unit 22 are buckled. The 223 is separated, and the user can remove the belt 211 of the adjusting unit 21 from the wearing portion 222 of the fastening unit 22, so that the user can take off the protective mask or re-adjust the headband adjusting mechanism. 2 elastic adjustment.

In addition, the present invention enables the adjustment unit 21 and the fastening unit 22 of the headband adjustment mechanism 2 to be removed from the limiting holes 11, 11a of the brim 1 by using the pivot shafts 213 and 224, respectively, so that the user can Remove the headband adjustment mechanism 2 for replacement (for example, replace the headband adjustment mechanism of different sizes or replace it with an elastic band).

In summary, the improved protective face mask of the present invention is effective in improving the lack of the formula, and the adjustment unit and the fastening unit provided by the headband adjustment mechanism can be used to adjust the appropriate tightness to make the head The belt adjustment mechanism conforms to the shape of the user's head. In addition, the headband adjustment mechanism can be removed and removed on the brim as needed, thereby making the headband adjustment mechanism difficult. Loose, comfortable and easy to disassemble and replace, the creation of this creation is bound to be more progressive, practical and meet the needs of users, has the basic requirements of patent applications, and propose new applications in accordance with the law.

However, the above-mentioned ones are only preferred embodiments of the present invention.
