Air dust particle/air sampler is a kind of instrument of air gathering atmosphere pollution or polluted; and the mode that current air dust particle/air sampler housing many employings plastic casing splices mutually with sheet metal; its intensity is more weak; instrument can not be protected well from collision injury; during assembling, case surface also can leave screw, affects attractive in appearance.In addition, ventilating heat dissipating hole of the prior art is distributed in shell two sides, can not effectively prevent the dust in air from entering instrument internal, can not thoroughly prevent rainwater from entering instrument internal from ventilating heat dissipating hole during rainy day sampling, cause instrument damage, and the face of the LCDs that current air dust particle/air sampler housing is installed is many becomes 90 degree with level ground, and liquid crystal touch display screen is easily subject to direct collision and causes liquid crystal touch display screen to break.
Utility model content
The purpose of this utility model is just to provide a kind of rain-proof dust-prevention type Instrument shell to solve the problem, it can realize the raising greatly of Instrument shell compactedness, can effectively prevent rainwater from entering instrument internal during sampling, and prevent the dust in air from entering instrument internal to a certain extent, reach rain-proof dust-proof.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of rain-proof dust-prevention type Instrument shell of the present utility model, comprise shell and base plate, wherein, described base plate is fixed with backboard to contact with described outer casing inner wall, one sidewall of described backboard and described shell, base plate form the parking space of instrument, another sidewall of described backboard and described outer casing inner wall form one to semi-enclosed heat radiation inner chamber of under shed, and described base plate and described backboard are provided with several ventilating heat dissipating holes.
Further, described heat radiation inner chamber bottom is provided with the electric fan to canyon.
Further, also comprise the display screen installing port being arranged on described shell front side face, the leading flank of described shell is the inclined-plane becoming 65 ° ~ 85 ° of angles with described base plate plane, and described display screen installing port both sides are provided with two Crashworthy plates.
Further, two described Crashworthy plates are separately positioned on the two sides institute of described shell in the plane.
Further, described Crashworthy plate and described shell are structure as a whole.
Further, described base plate and described backboard are structure as a whole.
The beneficial effects of the utility model are: shell of the present utility model makes the processing technology adopting aluminum compression mod, substantially increases the compactedness of Instrument shell; Its ventilating heat dissipating hole is distributed on base plate and backboard, instead of on shell, effectively prevent rainwater enter instrument internal when the rainy day samples, and the dust that also prevent to some extent in air enters instrument internal, reaches the effect of rain-proof dust-proof; The leading flank of shell of the present utility model is the inclined-plane becoming 65 ° ~ 85 ° of angles with base plate plane; display screen installing port both sides are provided with two Crashworthy plates; it is not only convenient to observed data, and Crashworthy plate can protect liquid crystal touch display screen to cause breaking of liquid crystal touch display screen from direct collision.
