Description

Improve the face shield fixed mount of structure

Technical field

The utility model relates to a kind of face shield fixed mount that improves structure.

Background technology

The fixed rack structure of traditional face shield, mainly be to be provided with in the fixed mount left and right sides and to insert the through hole of inlay card location slightly for face shield, and the length of general face shield the length than fixed mount is longer usually, and the setting of cooperation hatband, can be bent into required radian according to the head dummy size of human body by this in order to wearing, but because fixed mount is different with the radius of curvature of the emerald green bending of face, not only assembling difficulty, and easily cause user's inconvenience, the more normal situation that fracture is arranged slightly of inserting that is articulated in face shield and fixed mount of severe patient, and face shield only is pivoted on the fixed mount by pin, there is no stop part between the two and can make face shield be positioned the predetermined position of fixed mount, therefore often cause user's inconvenience.

Summary of the invention

The purpose of this utility model provides the face shield fixed mount of the improvement structure that a kind of user of being convenient to wears.

Above-mentioned purpose of the present utility model is to realize like this, a kind of face shield fixed mount that improves structure, fixed mount is formed by the punching out of plastic material one, being provided with the complex trace reinforcement in fixed mount one side reins in, each laterally stubborn folding is the skeleton frame of concavity in the fixed mount two ends, and stretching out in skeleton frame one can set firmly the placing part that positioning pivot pivots slightly for inserting, and be provided with a plurality of stop blocks in this placing part, and establish the location port that wears for hatband in the auspicious cutter in fixed mount end; Wherein, skeleton frame both sides frame is not contour, can be in fixed mount bending and during the device face shield, can provide a preferable applying angle, and then make and insert the elastic force effect that is difficult for slightly because of face shield and have and come off.

Be provided with plural clipping block in the location port of fixed mount of the present utility model both sides, can be when wearing, really fixedly hatband in the port of location and unexpected getting loose.

Of the present utility model insert reaching the prominent flange that can be placed in face shield apical margin through hole of establishing on the positioning pivot slightly, positioning pivot is engaged really with face shield, and then face shield can be pivoted on the fixed mount and unexpected dull, and the positioning pivot side protrudes out a stop block, this stop block can be replaced with the mutual inlay card of the stop block in the placing part, and the location and the rotation that positioning pivot can be pivoted on make suitable angle on the placing part.

The utility model is elaborated with instantiation below in conjunction with accompanying drawing.

Drawing reference numeral explanation: 1 fixed mount; 10 reinforcement are reined in; 11 skeleton frames; 12 placing parts; 121,142 stop blocks; 13 insert slightly; 131,141 flanges; 14 positioning pivots; 15 location ports; 151 clipping blocks; 16 packing rings; 161,31 through holes; 2 hatbands; 3 face shields.

The specific embodiment

Fig. 1 is the three-dimensional combination figure of the utility model one preferred embodiment, and referring to Fig. 2 B, can be clear that from figure, and the utility model mainly is by a fixed mount 1, a hatband 2, and a face shield 3 combines; Wherein fixed mount 1 mainly is to be formed by the punching out of plastic material one, be provided with the complex trace reinforcement in fixed mount 1 one sides and rein in 10, use and strengthen whole structure and flexibility, and in fixed mount 1 two ends each laterally stubborn folding is skeleton frame 11 of concavity, wherein, skeleton frame 11 both sides frames are to be not contour design (in addition referring to Fig. 3 A), inboard frame length is longer, stretching out in skeleton frame 11 one can be for inserting 13 placing parts that set firmly 12 slightly, be equipped with a flange 131 in pin 13 bottoms, this flange 131 is in harmony and can be placed in the through hole 31 on face shield 3 tops, can pivotly join a location pivot 14 in the placing part 12, this positioning pivot 14 outwards also extends a flange 141 (shown in Fig. 2 B) that can be placed in the face shield 3 top through holes 31, and protrude out a stop block 142 in the side of positioning pivot 14, this stop block 142 can be replaced with the stop block 121 mutual inlay cards in the placing part 12, and make positioning pivot 14 can be pivoted on the rotation of making certain angle on the placing part 12, and establish the location port 15 that can supply hatband 2 to wear in fixed mount 1 terminal cutter, be provided with plural clipping block 151 in this location port 15; Hatband 2 its materials are to be elastic material, can be in joining for a suitable elasticity binding force; Face shield 3 is provided with plurality of through holes 31 in the apical margin appropriate location.

When combination, 1 liang of fixed mount is auspicious little to crooked (shown in Fig. 2 A), and make 2 liang of auspicious location ports 15 that are arranged in fixed mount 1 end of hatband, and make fixed mount 1 crooked location be default radian, by the clipping block 151 in the location port 15, can be really fixedly hatband 2 in the port 15 of location and unexpected getting loose, and positioning pivot 14 is placed in the placing part 12, to insert 13 through hole 31 and positioning pivots 14 slightly again through face shield 3 apical margins, and be positioned on the placing part 12 of fixed mount 1, and make and insert slightly 13 and the flange 131 of positioning pivot 14,141 place respectively in the through hole 31 of face shield 3, promptly finish combination.

When using, can suitably set up a packing ring 16 according to the dimensional thickness of face shield 3, when the thinner thickness of face shield 3, then add a packing ring 16, insert slightly 13 and the flange 131 of positioning pivot 14 and make, 141 can engage with the through hole 31 of face shield 3 really, and then face shield 3 can be pivoted on the fixed mount 1 and unexpected dull, and by the not contour design of skeleton frame 11 both sides frames, in the time of can installing face shield 2 in fixed mount 1 bending, one preferable applying angle (shown in Fig. 3 B) can be provided, and then make slotting 13 difficult elastic force effects slightly that the anxiety that comes off be arranged because of face shield 2, and the stop block 142 by positioning pivot 14 is replaced with the stop block 121 mutual inlay cards in the placing part 12, and the location and the rotation that positioning pivot 14 can be pivoted on make suitable angle on the placing part 12, by above-mentioned structure, make the utility model wear facility to reach the user, and the structure of using flexibly.

By the above as can be known, the face shield fixed mount of improvement structure of the present utility model has really and wears comfortable effect, and has solved the problem that hatband and fixed mount are easy to come off.

The above is preferred embodiment of the present utility model only, is not to be used for limiting scope of the present utility model, and therefore all equalizations of doing according to the utility model training centre change and modify, and all fall into scope of the present utility model.
