Abstract
The utility model provides an air-filtering safety helmet which comprises a safety helmet body. A helmet shell on the helmet brim of the safety helmet body is provided with a plurality of fasteners, a protruding column is arranged between every two fasteners, an air-filtering helmet cover is connected to the fasteners in a clamped mode, the air-filtering helmet cover comprises an outer shell, an inner supporting frame, an outer supporting frame and a filtering membrane, the lower edge of the outer shell is provided with a plurality of screw holes, the two sides of the outer shell are respectively provided with an air outlet, and tube casings are arranged in the air outlets. The filtering membrane is arranged between the inner supporting frame and the outer supporting frame, the lower edge of the inner supporting frame and the lower edge of the outer supporting frame are provided with connecting holes, the connecting holes are matched with the screw holes in the outer shell, screws penetrate through the screw holes and the connecting holes to enable the inner supporting frame and the outer supporting frame to be connected with the outer shell, and then the air-filtering helmet cover is formed. The air-filtering safety helmet is simple in structure and convenient to use, has dual functions of a safety helmet and air filtering, improves impact resistance, is large in air-filtering area, good in effect, long in filtering membrane service life and low in cost, and guarantees health of workers.
Description
Technical field
The utility model relates to appliances for labor protection, especially a kind of air filtration safety cap.
Background technology
At present, safety cap is a kind of safety appliance that the staff of a lot of industries must wear, safety cap is that user protects head to alleviate injury at work, it only has the function of safety cap, and without the function of filtered air, at some dust, the enterprise that dust is larger, as mine, the enterprises such as cement plant, staff just need wear anti-dust respirator at work, and common anti-dust respirator is to carry out Chalk-dust filtering by dustproof filter membrane, but the diameter of filter membrane generally only has 6-8cm left and right, filter area is little, dust easily stops up filter membrane, therefore inspiratory resistance rises, need the frequent filter membrane of changing, otherwise cause human body uncomfortable, affect the result of use of anti-dust respirator.
Summary of the invention
The purpose of this utility model is improved above shortcoming exactly, provides a kind of simple in structure, easy to use, energy filtered air, and membrane filtration area is large, the air filtration safety cap that cost is low.
Concrete scheme of the present utility model is: air filtration safety cap, there is safety cap body, it is characterized in that: the cap shell of the shade top of safety cap body is provided with some clips, between clip, be provided with between two projection, on described clip, clamping connection has an air filtration calotte, and the overanxious calotte of described air includes shell, inner support frame, outer support frame and filter membrane, and the lower edge of described shell is provided with some screws, the both sides of shell are respectively provided with a venthole, are all furnished with pipe box in venthole; Between inner support frame and outer support frame, establish one deck filter membrane, the lower edge of inner support frame and outer support frame be equipped with shell on the connecting hole that matches of screw, inner support frame passes screw with outer support frame by screw and is connected with shell with connecting hole, forms air filtration calotte.
Described air filtration safety cap, is characterized in that: the clip on described cap shell is provided with 4-6.
Described air filtration safety cap, is characterized in that: the projection between described clip can be established 2-3.
The utility model is simple in structure, easy to use, has the dual-use function of safety cap and filtered air, not only improved the anti-impact force of safety cap, and air filtration area is large, effective, the service time of filter membrane is long, and cost is low, has guaranteed that staff's is healthy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is explosive view of the present utility model.
In figure, 1-safety cap body, 2-clip, 3-projection, 4-inner support frame, 5-outer support frame, 6-connecting hole, 7-shell, 8-venthole, 9-pipe box, 10-screw, 11-filter membrane.
The specific embodiment
Referring to Fig. 1-2, the utility model air filtration safety cap, there is safety cap body 1, the cap shell of the shade top of safety cap body 1 is provided with some clips 2, is provided with between two projection 3 between clip, and on described clip 2, clamping connection has an air filtration calotte, the overanxious calotte of described air includes shell 7, inner support frame 4, outer support frame 5 and filter membrane 11, the lower edge of described shell 7 is provided with some screws 10, and the both sides of shell 7 are respectively provided with a venthole 8, is all furnished with pipe box 9 in venthole 8; Between inner support frame 4 and outer support frame 5, establish one deck filter membrane 11, the lower edge of inner support frame 4 and outer support frame 5 be equipped with shell on the connecting hole 6 that matches of screw 10, inner support frame 4 passes screw 10 with outer support frame 5 by screw and is connected with shell 7 with connecting hole 6, forms air filtration calotte; Clip 2 on described cap shell is provided with 4-6; Projection 3 between described clip can be established 2-3.During installation, first filter membrane is clipped between inside and outside bracing frame, then with screw, inside and outside bracing frame is fixing in the enclosure, form air filtration calotte, again air filtration calotte is clipped on the clip of safety cap, projection on safety cap withstands the lower edge of the inner support frame of air filtration calotte, makes to leave certain gap between air filtration calotte and safety cap, and the pipe box of the shell both sides of last air filtration calotte only need be connected and can use with the air inlet pipe of the face shield that matches; Airfiltering principle is, air enters the gap between air filtration calotte and safety cap, in air filtration calotte, by filter membrane, filters, and the air after filtration out enters in face shield from gas outlet.Filter membrane diameter of the present utility model is 40-50cm, be the 30-45 of common dust mask filter membrane area doubly, inspiratory resistance obviously improves, and breathes freely comfortablely, is applicable to various dust works place.
