Abstract
The utility model designs a kind of waterproof gas detecting instrument, comprise front cover shell, rear casing, inner housing, detecting unit, display unit, hummer, first pad, described front cover shell is connected with rear casing, inner housing is provided with in it, described inner housing is provided with detecting unit, display unit and hummer mounting hole, described hummer mounting hole is divided into, in, lower three parts, mid diameter is little compared with upper and lower, described hummer is arranged on the hummer mounting hole top of inner housing, described first pad is annular, be arranged in hummer mounting hole top, between hummer and hummer mounting hole, the utility model structure is simple, there is water-proof function, increase the serviceable life of product.
Description
Technical field
The utility model relates to a kind of waterproof gas detecting instrument, and particularly a kind of gas detecting instrument of Portable movable, belongs to mechanical field.
Background technology
Common portable gas detector all can be provided with on inner housing hummer mounting hole for installing hummer, this hummer mounting hole communicates with external environment.When air humidity in external environment is comparatively large or gas detecting instrument has moisture, moisture can flow to gas detecting instrument easily via hummer mounting hole, affects the use of instrument, reduces the serviceable life of instrument.
Utility model content
Utility model object: the purpose of this utility model is to solve above the deficiencies in the prior art, provides a kind of gas detecting instrument with water-proof function.
Technical scheme: waterproof gas detecting instrument described in the utility model, comprise front cover shell, rear casing, inner housing, detecting unit, display unit, hummer, first pad, described front cover shell is connected with rear casing, inner housing is provided with in it, described inner housing is provided with detecting unit, display unit and hummer mounting hole, described hummer mounting hole is divided into top, middle part, three, bottom part, mid diameter is little compared with upper and lower, described hummer inserts hummer mounting hole top, described first pad is annular, be arranged in hummer mounting hole top, so effectively can be stopped by the first pad when moisture flows to hummer mounting hole along the gap of hummer on hummer mounting hole, middle part and the bottom of hummer mounting hole can not be flow to further.
In order to solve the problem further, also comprise the second pad, described second pad is annular, is positioned at the bottom of the hummer mounting hole of inner housing, can stops that moisture enters gas detecting instrument along the bottom of hummer mounting hole further.
In order to solve the problem further, described first pad and the second pad are made up of rubber, because rubber is the material with very strong elasticity, so certain pressure can be applied to it when mounted, utilize the elastic deformation of material effectively can reduce space, increase the sealing property of the first and second pads.
Beneficial effect: waterproof gas detecting instrument disclosed in the utility model, structure is simple, can effectively prevent moisture from entering gas detecting instrument.
Accompanying drawing explanation
Fig. 1 is inner housing, hummer structural representation,
Fig. 2 is the inner shell structure schematic diagram being provided with the first pad and the second pad.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
See Fig. 1 to 2, the utility model discloses a kind of waterproof gas detecting instrument, comprise front cover shell, rear casing, inner housing 10, detecting unit, display unit, hummer 11, first pad 12, described front cover shell is connected with rear casing, inner housing 10 is provided with in it, described inner housing 10 is provided with detecting unit, display unit and hummer mounting hole, described hummer mounting hole is divided into top 21, middle part 22, 23 3, bottom part, middle part 22 diameters compared with top 21 and bottom 23 little, described hummer 11 is arranged on the hummer mounting hole top 21 of inner housing 10, described first pad 12 is annular, be arranged in hummer mounting hole top 21.Second pad 13 is annular, is positioned at hummer mounting hole bottom 23, and when installing inner housing 10, hummer mounting hole bottom 23 is connected with rear casing.Certain first pad 12 and the second pad 13 are also being circular.First pad 12 and the second pad 13 are made up of rubber in the present embodiment, certainly also can be made up with regard to resilient material of other.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
