Through the utility model provides a pair of waterproof case, the through -hole upper end that can get into sleet on the engine case shell with the advertisement machine sets up the protection casing to seal in engine case shell advertisement machine is whole, effectively prevented the way that sleet got into, still do not influence the heat dissipation and broadcast image of advertisement machine, but make this advertisement machine anytime and anywhere use not receive the restriction in all ring edge borders.
Description
Technical field
The utility model relates to shell field, specifically a kind of waterproof case.
Background technology
Be not subject to mounting medium to affect, have the laser advertisement machine that high brightness can project at a distance, use out of doorsTime need to do to complete machine the processing of moistureproof and waterproof. If sleet or floating dust etc. enter into the shell of projectorIn, the normal work of projector is caused to adverse effect. Existing laser advertisement machine major part is not done waterproof and is arrangedExecute, can not directly use out of doors. Conventionally way is to build a civil engineering houselet, in laser advertisement machine is placed onFace, sees through clear glass and outwards throws in advertisement; Or laser advertisement machine is placed on to the indoor clear glass that sees through to be thrownBe shot out, such way makes the environment for use of laser advertisement machine be subject to very big limitation.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, and the way of existing laser advertisement machine waterproof makes laserThe environment for use of advertisement machine has been subject to very big circumscribed problem, has proposed a kind of waterproof case, for realizingLaser advertisement machine whenever and wherever possible complete machine is directly outdoor available, is not subject to impact and the limitation of surrounding enviroment.
In order to solve above-mentioned technical problem, the basic technical scheme the utility model proposes is:
A kind of waterproof case, comprises the chassis shell that a hollow is sealed, and the front end face of described chassis shell arranges a throwingShadow through hole, for exposing built-in projection lens to the open air; Described chassis shell arranges an opening above projection through holeThe first downward protective cover, for preventing that the impurity such as sleet from entering chassis shell by projection through hole; Described cabinetShell is provided with some ventilating openings for one week along middle part, outer face, and chassis shell arranges one along the top of some ventilating openingsFormula the second protective cover that Open Side Down, for preventing that the impurity such as sleet from entering chassis shell by ventilating opening.
Preferably, the rear side of each described ventilating opening is all fixed a DC fan, for outwards distributing middle level skyInterior heat prevents that extraneous impurity from entering against the wind simultaneously.
Preferably, the inner bottom surface of described chassis shell arranges wind direction heat conduction fan upward, for by chassis shellThe heat that bottom produces is pushed to top, then takes heat out of chassis shell by the DC fan of ventilating opening. ShouldStructure has ensured complete seal light source mechanism, has avoided entering impurity from the external world.
Preferably, described chassis shell adopts stainless steel to make, firm waterproof.
Preferably, the low eaves formula structure in high both sides in the middle of the top of described chassis shell adopts, for avoiding rainThe accumulation of snow day sleet, ensures the reliable use of complete machine out of doors.
Preferably, owing to being that outdoor use must relate to lightning protection measures, the inside of described chassis shell arranges oneArrester, effectively protects equipment not by broken by lightning.
Preferably, the bottom center of described chassis shell is fixed a supporting seat, and prop up relatively the bottom surface of described chassis shellA stacker is fixed in the position of support seat, the described stacker supporting seat that is slidably connected, and described stacker is fixed on onePlace in gripper shoe in the plane, for adjusting the new line angle of chassis shell.
Preferably, a clear glass piece is filled in the projection through hole on described chassis shell.
The beneficial effects of the utility model are: a kind of waterproof case providing by the utility model, and by advertisementThe through hole upper end that can enter sleet on the chassis shell of machine arranges protective cover, and by advertisement machine integrally closed at cabinetIn shell, effectively prevent the approach that sleet enters, also do not affected heat radiation and the playing video of advertisement machine, madeThis advertisement machine can be used the restriction that is not subject to surrounding enviroment whenever and wherever possible.
Brief description of the drawings
The external structure figure of the waterproof case that Fig. 1 provides for the utility model embodiment;
Identifier declaration in figure: 1-chassis shell, 2-projection through hole, 3-the first protective cover, 4-ventilating opening, 5-secondProtective cover, 6-eaves formula structure, 7-supporting seat, 8-stacker, 9-gripper shoe.
Detailed description of the invention
Below with reference to accompanying drawing 1 and embodiment, the utility model is described further, but should come with thisLimit protection domain of the present utility model.
As shown in Figure 1, the utility model provides a kind of waterproof case, comprises the cabinet of a hollow sealingShell 1, the front end face of described chassis shell 1 arranges a projection through hole 2, for exposing built-in projection lens to the open air;Described chassis shell 1 arranges first protective cover 3 that Open Side Down above projection through hole 2, for preventingThe impurity such as sleet enter chassis shell 1 by projection through hole; Described chassis shell 1 arranges along middle part, outer face for one weekHave some ventilating openings 4, chassis shell 1 arranges the second protective cover 5 of integral type along the top of some ventilating openings 4,Be used for preventing that the impurity such as sleet from entering chassis shell 1 by ventilating opening. Preferably, the projection on described chassis shellA clear glass piece is filled in through hole.
Preferably, the rear side of each described ventilating opening 4 is all fixed a DC fan, for outwards distributing middle levelHeat in space prevents that extraneous impurity from entering against the wind simultaneously.
Preferably, the inner bottom surface of described chassis shell 1 arranges wind direction heat conduction fan upward, for by cabinetThe heat that shell bottom produces is pushed to top, then takes heat out of chassis shell by the DC fan of ventilating opening.This structure has ensured complete seal light source mechanism, has avoided entering impurity from the external world.
Preferably, described chassis shell 1 adopts stainless steel to make, firm waterproof.
