Description
Technical field
The utility model relates to personal protective equipment field, is specially a kind of novel large eye window gas mask.
Background technology
Large visual field gas mask kind is a lot of in the market, for the demand of satisfied different occasion mainly contains portable filtration mask, is worn on left side or the right side of face shield by canister; Also the air-supply face shield of promising reduction respiratory resistance, or compressed-air actuated long-tube face shield is provided.But these face shields all can not for the librarian use of wearing glasses, can not permissible call in a noisy environment, the visual field that only slightly specifies than GB2890-2009 " respiratory protection self-absorbing filtering type gas defence face shield ", the visual field of these face shields is large simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of multi-functional large eye window gas mask, meets wearing of most people.
The utility model adopts following technical scheme to realize:
A kind of large eye window gas mask, comprise cover body, large eye window eyeglass is installed by eyeglass clip in described cover body top; The positive basifacial of described cover body installs compound main communication, and described compound main communication comprises call body, and the bottom of described call body arranges expiration valve seat, and described expiration valve seat central part installs outlet valve sheet; Described call body upper part is propped up and is obliquely installed call seat, the call mouth UNICOM on described call seat and call body top; Install metal call film by O type circle in described call seat, described metal call film is fixedly installed in call seat by connecting clamping frame.
Eyeglass is fixed on cover body by eyeglass clip by novel large eye window gas mask, and to be fixed on cover body by compound main communication by main communication clip and to form gas mask.Be placed on the valve fixing hole of expiration valve seat by conventional outlet valve sheet during use, and form airtight circle on contact surface boss, during guarantee personnel's air-breathing, external air flow can not enter in face shield.This large eye window gas mask adopts compound communication body structure outlet valve and call body being integrated one, and body of conversing loads in face shield, by the fixing communication of breathing of cassette tape on face shield, carries out face shield air leakage test, meets airtight requirement.
Further, the upper side in expiration valve seat of described call body arranges electroacoustic component interface.When being equipped with electroacoustic function element, connected by electroacoustic component interface, place lapel mike in main communication inside, microphone joint and the inner connecting hole of main communication couple together, and the sound that personnel are sent is transferred to the signal of telecommunication and spread out by the outside element that amplifies simultaneously.
Further, in order to the personnel of wearing spectacles can be made also to wear a gas mask, and eyesight is unaffected, adds vision correction mechanism.Be positioned at inside described cover body to arrange directly over eyeglass connect convex, the convex upper installation vision correction structure of described connection, described vision correction structure comprises Connection Block, axially be connected bottom described Connection Block positioning screw rod, on described positioning screw rod, threaded engagement installs stop nut and lower position nut, described positioning screw rod is set with between upper limit nut and lower position nut upper fixing element and lower fixture; The bridge of the nose section of spectacle frame is fixed between fixed and lower fixture.
During use, lens edge is placed in face shield draw-in groove, vision correction structure is placed on eyeglass fixing hole, spectacle fixing frame (both sides leg) disassembles when wearing face shield by the personnel of wearing glasses, retain picture frame, picture frame intermediate transverse girder position is placed between the upper fixing element of brace and lower fixture, is regulated the height of picture frame by upper and lower stop screw.
The technical problem that the present invention solves is to provide the gas mask that personnel that a kind of confession wears glasses wear, and can coordinate with the element that amplifies the face shield improving call performance, the mask wearer structure of its uniqueness can be the personnel of wearing and provides wide visual field more in addition simultaneously.
This gas mask designs two numbers types, can meet wearing of most people, newly-designed eyeglass effectively can improve total visual field and the binocular field of view of face shield, its total visual field reaches 92%, binocular field of view reaches 83%, than the total visual field 70% that GB2890-2009 " respiratory protection self-absorbing filtering type gas defence face shield " specifies, binocular field of view 55% improves 31% and 51% respectively, this face shield will effectively improve the position consciousness of the personnel that wear in enclosed environment, for the personnel of wearing provide more wide visual field, simultaneously reserved electroacoustic telephony interface can make face shield together with the element fusion that amplifies, strengthen the call function of face shield, the fixed mount mated with glasses is set up in addition in eyeglass upper end, can the glasses of near-sighted personnel be arranged in face shield, also the function can worn glasses the while of achieving masked.
The key technical indexes of the present utility model be to improve face shield wear after total visual field and binocular field of view, design new-type eyeglass simultaneously, making face shield good looking appearance, on eyeglass, be aided with eyesight correction device in addition, near-sighted personnel can being made to wear this gas mask when retaining glasses.
