Abstract

The utility model discloses a lifting facial fire-fighting thermal imager, wherein the middle-lower part in the transparent glass of the existing fire-fighting face mask is internally and externally provided with a box respectively; the inner box is provided with a battery, an electric motor, a gear, a rack and a lifting box; the inner box is internally provided with a micro-display, the bottom of which is provided with a thermal imager power switch; and the outer box is provided with a thermal imager and an electric motor switch. The thermal imager power switch is switched on when the electric motor drives the lifting box to lift up to a dead point, and a user can see a virtual image of amplified object through a near-eye observation hole of the display. The utility model frees the hands without carrying with hands, thereby overcoming the problems of large view screen since the display is arranged outside the cover, high cost, and unclear observation due to bad environmental influence, and also overcoming the disadvantage that a fixed facial fire-fighting thermal imager always shields one eye. The thermal imager can be manufactured on all existing fire-fighting full face masks with large space, and can be embedded on the original frame of the existing fire-fighting full face mask with small space by reconstructing the transparent glass but the edge shape cannot be changed. The utility model is special fire-fighting device and is applicable to fire-fighting situations.

Description

Liftable face mask type fire-fighting thermal imager

Technical field

The utility model relates to a kind of liftable face mask type fire-fighting and holds the picture instrument

Background technology

The fire-fighting thermal imager, fire fighting in smog, use when rescuing people etc., it can see through dense smoke, see object clearly, equipped more general limit at present abroad, but on version, be that employing is portable mostly, the i.e. thermal imager of portable a band small display, portable an instrument enters the dense smoke field, for example the product F of the upright greatly company in Hangzhou ₂The special-purpose thermal imager of series fire-fighting, another kind is a helmet-type, promptly thermal imager is contained on the helmet, and display places OFP at the moment, U.S. RJ-9 type helmet-type thermal imager for example, these products the former need portablely, do not liberate both hands, and latter's structure is complicated, and bigger shortcoming be their display all at OFP, far away from order like this, screen needs big cost height, and because of interference such as cover foreign cigarette, steam, dirt, it is not too clear to look thing.Except above-mentioned points, Zhejiang Province Leibang Industry Co., Ltd is also producing a face mask type fire-fighting thermal imager, and it is installed in display in the face shield, compact conformation, looking thing, to put fruit clearly good, but also covered the sight line of an eye at ordinary times, 180 ° specification requirement about not reaching smoke helmet and seeing at ordinary times.

Summary of the invention

The purpose of this utility model is the shortcoming at the existence of above-mentioned thermal imager, and a kind of liftable face mask type fire-fighting thermal imager is provided.Achieve the above object for this reason, the utility model has adopted the elevated principle of the periscope on the submarine, promptly the rubber mouth and nose in side middle and lower part and the cover protect between the bowl within the clear glass in existing fire-fighting full facepiece mask, the rectangular-shaped cover inner box that an outside becomes camber is set, box is divided into several chambers, it is the battery chamber, motor room wiring board chamber and gear, the lifting box lead-frame that the tooth plate chamber becomes with circummure by inner box, top in the lifting box is being provided with display, lifting box front side is vertical is being provided with a tooth bar, it is meshed with motor gear, motor rotates like this, just can make the rise of lifting box or falls.

The lifting box bottom before inboard, a thermal imager mains switch is being set, when box is raised up to top dead-centre, this switch opens, thermal imager is started working, the picture that thermal imager obtains just can have been seen in the display inspection hole of rise.Above the respiratory siphon heel of the middle and lower part, the outside of cloche near the full cover of former fire-fighting, fixing the outer box of a cover, it is made up of end box and lid two parts, in establish thermal imager.Inside and outside 2 boxes are after the waterproof washer is filled out in the transparent bright cloche outside, link to each other with screw, and have inside and outside the guide hole perforation.

The utility model compared with prior art has following distinguishing feature and good effect.

1, fire-fighting thermal imagery manual-free is carried, has been liberated both hands, the portability more tools with do more action.

2, the display because of thermal imager places in the face shield, has avoided the influence of extraneous adverse circumstances, makes clear picture, also owing to apart from eye closely, can reduce screen, reduces cost.

3, because of display can descend, increased the visual field, 180 ° specification requirement about reaching.

4, simple in structure, easy to make, waterproof, thermal insulation are good.

The utility model is the fire-fighting special equipment, is applicable to the fire-fighting occasion.

Below in conjunction with accompanying drawing and embodiment, the utility model will be further described:

Description of drawings

Accompanying drawing 1 is the utility model overall structure and office's cutaway view.

Accompanying drawing 2 be the utility model A-A to cutaway view.

Embodiment:

Shown in accompanying drawing 1,2, the utility model divides two parts, is formed by connecting with screw (18).First partly is cover inner box (1), loam cake (4) is arranged, lower cover (5) is formed, be arranged on the inboard, middle and lower part of glass transparent glass (20), and mouth and nose protect between the bowl (30), the left side is battery chamber (22) in the box, middle upper portion is motor room (23), built-in motor (24), the bottom is line wiring board chamber (25) and wiring board (32), the place ahead, right side is specially moving chamber (26), in motor arranged pinion (13) be meshed with it be fixed on tooth bar (12) on the lifting box (2) and thrust pellet shot from a slingshot (11), its rear is lifting box (2) and lead-frame (27) thereof, the first half in lifting box (2) is display room (28), is equipped with a miniature nearly order display (29), and lower front wall is provided with a thermal imager mains switch (10); Second partly is cover outer box base (14) and lid (15) thereof, with screw (17) they are twisted and to close, be arranged on the middle and lower part of cloche (20), locate near outgoing call haustorium joint (31), built-in thermal imager (7) and wiring board (8) thereof also are provided with two motor direction switches (16) outside box.
