Embodiment
Shown in Fig. 3 A, Fig. 3 B, be the first embodiment of the invention schematic representation.Fig. 3 A, Fig. 3 B are from different perspectives to embodiment's signal.Face shield 100 upper process form a fixed block 20, and this fixed block 20 is provided with the 3rd perforate 21.Other is provided with movable part 30, is the U-shaped metal parts, is provided with crossbeam 33 and bipod 34,35, and this bipod is provided with first perforate 31 and second perforate 32.During installation splayed shape spring 13 of the prior art is penetrated on the movable part 30 of U-shaped, be socketed on the crossbeam 33, again movable part 30 is enclosed within on the above-mentioned projection fixed block 20, make first perforate 31 on the bipod 34,35 of movable part 30 and second perforate 32 encase the 3rd perforate 21 on the fixed block 20, and above-mentioned three perforates are connected, pass above-mentioned three perforates with screw 12 again, just, screw 12 passes first perforate 31, the 3rd perforate 21, second perforate 32, thereby movable part 30 is fixed on the fixed block 20.In the present embodiment, the slightly larger in diameter of the 3rd perforate 21 is in the diameter of described first perforate 31 and second perforate 32, therefore screw 12 does not contact the 3rd perforate 21, and only contact and apply power thereon with second perforate 32 with first perforate 31 of this movable part 30, thus this movable part 30 is fixedly mounted on the fixed block 20.Because screw 12 does not directly contact with fixed block 20, just can not make fixed block 20 produce stress yet, and then can not destroy face shield yet, promptly face shield can not fall, and has improved Security.Except using screw 12 as the link, bolt or latch etc. also is fine.
As shown in Figure 4, be the second embodiment of the invention schematic representation, be with first embodiment's difference, crossbeam 33 extends to form extension part 36 and crooked to transverse direction, crooked end 37 snaps in the shrinkage pool of establishing on the face shield 100 101, and spring 13 is socketed on this extension part 36, because end 37 snaps in the shrinkage pool 101 of face shield 100, so spring 13 can not come off.Screw 12 passes first perforate 31, the 3rd perforate 21, second perforate 32, and then movable part 30 is fixed on the fixed block 20.Comparison diagram 4 and Fig. 3 B are as seen, the angle that movable part 30 inserts spring 13 among both is different, 90 degree have been changed, because the change of angle, the height of the dotted portion among Fig. 3 B, the height that is crossbeam 33 outstanding face shields 100 has not had, and has so just reduced the height that spring 13 is installed, and using scope is wider.
Fig. 5 A, Fig. 5 B, Fig. 5 C are the third embodiment of the invention schematic representation, and Fig. 5 A signal fixed block 20 wherein, Fig. 5 B illustrates movable part 30, Fig. 5 C to illustrate the state of integral installation of the present invention on face shield 100.As shown in the figure, fixed block 20 is inverted U-shaped projection.Inverted U-shaped top is provided with the 3rd perforate 21.Movable part 30 is horizontal U-shaped metal parts, and bipod 34,35 is provided with first perforate 31 and second perforate 32.First perforate 31 is the perforate to in-flanges, owing to use flued opening, can use sunk screw to fix the live metal sheet, under the situation that does not increase height, and the location of portable propelling spare 30 and fixed block 20.The pin 34 that is provided with first perforate 31 is to extending to form extension part 36 and crooked with the parallel direction in horizontal U-shaped top, and face shield 100 is withstood in crooked end 37.
During installation, splayed shape spring 13 of the prior art is inserted on extension part 36, again the pin that is provided with second perforate 32 35 of movable part 30 is passed inverted U-shaped fixed block 20, first perforate 31 is positioned at above inverted U-shaped fixed block 20 top drillings 21, and second perforate 32 is positioned at below inverted U-shaped fixed block 20 top drillings 21, three holes connect, and screw 12 passes this three hole, and fixedly movable part 30.Face shield 100 is withstood in the end 37 of the bending of extension part 36 at this moment, and then spring 13 is socketed between fixed block 20 and the movable part 30, can not come off.See also Fig. 5 C again, visible present embodiment is vertical mounting type, and movable part 30 inserts fixed block 20 from right to left, insert the back only screw 12 need be aimed at first perforate 31 just can, very laborsaving and save time when assembling.And because screw 12 direct touch fasteners 20 does not make fixed block 20 produce stress, so face shield 100 can not produce be full of cracks, so can not fall, improved Security.
Fig. 6 is the fourth embodiment of the invention schematic representation.Be with the 3rd embodiment's difference, increase by a reinforcer 22 in the end face one of fixed block 20, be provided with the 4th perforate (not shown) in the middle of this reinforcer, the 3rd perforate 21 at the 4th perforate and inverted U-shaped fixed block 20 tops connects.After having increased above-mentioned reinforcer 22, increased the thickness and the intensity of inverted U-shaped fixed block 20 end faces, made horizontal U-shaped movable part 30 can be easily fixed to this place, the efficient when improving completed knocked down products.
In addition, also on fixed block 20, be provided with several stiffening ribs 24.The setting of stiffening rib has been strengthened fixed block 20 and has been fixed on intensity on the face shield, more can not break away from face shield.
Fig. 7 is the fifth embodiment of the invention schematic representation.Be the different of fixed block 20 with the 3rd embodiment's difference.The position of top the 3rd perforate is promptly avoided in the position of internal deviation the 3rd perforate (not shown) of fixed block 20, is provided with the wall 26 that stretches out from face shield, and this wall 26 is connected with fixed block 20, and and fixed block 20 tops between leave space 27.The pin that is provided with second perforate 32 35 of movable part 30 passes this space 27.Distance between first perforate 31 in the present embodiment and second perforate 32 equals the distance in this space 27, can certainly be greater than the distance in this space 27.
At this moment, mounting type is identical with the 3rd embodiment.But because the pin 35 of 26 pairs of movable parts 30 of wall has the holder of Sheng effect, when tightening up a screw, can be without the fixing movable part 30 of another hand, direct just can tightening the screw, reduced assembling man-hour.
Fig. 8 is the sixth embodiment of the invention schematic representation.Also be the different of fixed block 20 with the 3rd embodiment's difference.The position of top the 3rd perforate 21 is promptly avoided in the position of internal deviation the 3rd perforate 21 of fixed block 20, is provided with the cylinder 28 that stretches out from face shield, and leaves space 27 between these cylinder 28 tops and inverted U-shaped fixed block 20 tops.The pin (not shown) that is provided with second perforate of movable part passes this space 27.Distance between first perforate in the present embodiment and second perforate equals the distance in this space 27, can certainly be greater than the distance in this space 27.
At this moment, mounting type is identical with the 3rd embodiment.But because 28 pairs of movable parts of cylinder pin of being provided with second perforate has the holder of Sheng effect, when tightening up a screw, can be without the fixing movable part of another hand, direct just can tightening the screw, reduced assembling man-hour.
