Abstract
The utility model relates to cap-type oxygen measuring equipment which is firmer, safer, faster and more convenient, and comprises a housing and a measuring equipment body arranged inside the housing, wherein the housing comprises a front housing and a rear cover; the rear cover is designed to be shaped like a cap; and the front housing is fixed on the rear side of the cap-type rear cover through a fastener.
Description
Technical field
The utility model relates to a kind of apparatus for determination of gas, particularly a kind of hat type oxygen determinator.
Background technology
At present under coal mine because environment reason, have methane gas to produce naturally, methane concentration transfinites in air, when oxygen concentration is hanged down line, entail dangers to people's life security.
In the prior art, generally adopt portable oxygen determinator, this analyzer need be placed on that waist is seen or hand held in, use very inconvenient; Also have oxygen determinator is inhaled on safety helmet by the form of magnet, because magnet weight is very big, drop easily, safety can not be guaranteed.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of more firm, safer, hat type oxygen determinator more easily at above drawback.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of hat type oxygen determinator, by housing with place the analyzer body of housing to form, wherein, described housing is cap structure.
A kind of hat type oxygen determinator, wherein, described housing rear end is provided with two draw-in grooves, and analyzer body rear end is provided with boss, and during connection, the dual-side of described boss snaps in the corresponding described draw-in groove.
Above-mentioned a kind of hat type oxygen determinator, wherein, described housing front end is provided with safety miner's lamp, and described safety miner's lamp is installed on the housing front end by screw.
Beneficial effect of the present invention is: bonnet is designed to hat type, fixedlys connected with procapsid by fastener, and is more firm, lighter, increases safety and the convenience of using greatly.
Description of drawings
Fig. 1 is lateral view of the present utility model
Fig. 2 is front view of the present utility model
Fig. 3 is sectional view of the present utility model
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of hat type oxygen determinator as shown in the figure, by housing 3 with place the analyzer body 1 of housing to form, wherein, housing 3 is designed to the structure of safety helmet, housing 3 rear ends are provided with two draw-in grooves 6, analyzer body 1 rear end is provided with two boss 7,, analyzer body 1 is connected with housing 3 by the mode of inserting.Simultaneously, housing front end 4 is provided with safety miner's lamp 5, and described safety miner's lamp is installed on the housing front end 4 by screw
Oxygen determinator body 1 comprises oxygen sensor, oxygen signal amplification circuit, A/D change-over circuit, sound light alarming circuit and display circuit, oxygen determinator body 1 is placed in the housing, the start back is monitored oxygen density value in the air in real time, the concentration range of monitoring is 0-25%, when oxygen concentration is lower than the alarm point of setting, warning circuit is reported to the police, and display shows current oxygen density value.
In sum, the utility model product before is more firm, lighter, increases safety and the convenience of using greatly, has farthest guaranteed user of service's personal safety.
Here description of the present utility model and application is illustrative; be not to want with scope restriction of the present invention in the above-described embodiments; therefore, the present invention is not subjected to the restriction of present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
