Detailed Description

The utility model is further described in the following embodiments with reference to the figures, see fig. 1-3:

a bandeau for wearing respirator face guard, with the bandeau 1 of the laminating mutually of hindbrain spoon, both ends all are provided with latch mechanism 2 about the bandeau 1, and latch mechanism 2 that is located the bandeau 1 left end is including shaping in the hasp board 20 of bandeau 1 left end, has seted up rectangle knot hole 21 on the hasp board 20, and the right side wall in the rectangle knot hole 21 has tongue board 22 to the left shaping, and the lower terminal surface of tongue board 22 is the deformation angle that forms to be less than 180 with the lower terminal surface of hasp board 20, bandeau 1 and latch mechanism 2 injection moulding as an organic whole.

In the specific use process, firstly, the left end and the right end of the respirator mask are fixed with elastic bands for wearing, and the elastic bands are made of adhesive tapes. Before the headband is used, the left end of a locking plate of the left locking mechanism 2 is pushed upwards, the left end of the lock tongue plate 22 is pushed to the upper end of the locking plate 20, the left end of the lock tongue plate is deformed, then an elastic band is inserted into the rectangular buckling hole 21 from the lower part of the left end of the lock tongue plate 22, and the elastic band is locked by utilizing the elasticity generated by deformation of the lock tongue plate, so that the headband is installed; the left locking mechanism is the same.

The girdle 1 on the head belt is made of plastic, has certain structural strength, and can fix and wrap the hindbrain spoon, thereby achieving good fixing effect; when the elastic band is adjusted, the fixing length of the elastic band can be adjusted by only pulling the bolt plate 22 to a large deformation degree.

Preferably, a hinge thin plate 23 is formed between the bottom of the right end of the latch plate 22 and the bottom of the right side wall in the rectangular buckling hole 21, the right end surface of the latch plate 22 is perpendicular to the upper surface of the latch plate 22, the right side wall in the rectangular buckling hole 21 extends leftwards and is formed with an abutting surface inclined plate 210, the right end of the latch plate 22 rotates in the right side wall in the rectangular buckling hole 21 through the hinge thin plate 23, and when the left end of the latch plate 22 rotates to the highest position, the right end surface of the latch plate 22 abuts against the abutting surface inclined plate 210.

In the above structure, the hinge thin plate 23 mainly has the function of enabling the latch plate 22 to have a certain deformation amount during the hinge process so as to prevent breakage; in addition, when the left end of the latch plate 22 rotates to the highest position, the right end surface of the latch plate 22 is propped against the propped surface inclined plate 210, so as to provide a proper hinging range and avoid the phase change of the latch plate 22 from breaking.

Preferably, the lower surface of the left end of the latch plate 22 is formed with a plurality of first friction protrusions 220 extending downward and parallel, and the left side wall in the rectangular buckle hole 21 is formed with a plurality of second friction protrusions 211 extending rightward, and the first friction protrusions 220 and the second friction protrusions 211 are longitudinally staggered. The first friction protrusions 220 and the second friction protrusions 211 which are staggered in the longitudinal direction can lead the tongue locking plate 22 to have good guiding function in the deformation process, so that the tongue locking plate is not easy to twist, and the tongue locking plate is more fastened when an elastic band is locked.

Preferably, the lower end surface of the second friction protrusion 211 is an inclined surface. The first friction protrusion 220 can be smoothly moved upward to generate deformation.

Preferably, the left end of the inner wall of the rectangular button hole 21 is formed with a button portion 212. The end of the locking plate is held when the user wears the elastic band.
