Abstract

The utility model provides a reflective-type projector housing comprising a plastic housing. The upper surface of the plastic housing is provided with a projection of a trapezoid-bench structure. The front and the rear surfaces of the trapezoid-bench structure are both provided with signal receivers. The front surface of the trapezoid-bench structure is also provided with a projection window. The reflective-type projector housing also comprises dustproof glass and a heatproof heat radiation window. The dustproof glass is laid on the projection window. The heatproof heat radiation window is molded through individual processing and is then arranged on a side surface of the plastic housing. The main advantages of the reflective-type projector housing of the utility model are that a projector lens is well protected and will not be polluted by dust; the projection effect is good; a signal reception scope is large; the usage is convenient; and the heatproof heat radiation window employs heatproof materials and is molded individually, thereby saving production costs.

Description

A kind of reflection-type projector shell

Technical field

The utility model relates to a kind of projector shell, relates in particular to a kind of reflection-type projector shell.

Background technology

Projector is used very extensive in the occasion such as meeting room, classroom, the projection lens of projector was all that directly sudden and violent leakage is aerial in the past, and dust is easy to fly into the camera lens that depollutes, and affects drop shadow effect; In projection process, mercury vapor lamp is steeped oneself-meeting and is emitted light and heat, and local temperature is raise, so the projector shell of producing need possess local heat-resisting function, if adopt one production can cause the increase of cost.Also have the projector shell surface before being exactly to be only provided with a signal receiver at a place, make signal range of receiving less, and if signal receiver one break down, will bring a lot of inconvenience.

Summary of the invention

The technical problems to be solved in the utility model; be to provide a kind of reflection-type projector shell; transform by projection window and radiator window to projector shell; be provided with multiple signal receivers simultaneously in many places; the camera lens of projector is better protected; the range of receiving of signal is wider, and production cost decreases.

The utility model is achieved in that a kind of reflection-type projector shell, comprises that a upper surface is provided with the plastic casing of a projection, and the front surface of described projection is provided with a projection window; Also comprise a dustproof glass, a plurality of signal receiver and a heat-resisting radiator window; Described dustproof glass is laid on described projection window; Described a plurality of signal receiver is spaced apart in the forward and backward surface of described projection; Described heat-resisting radiator window is located at the side of plastic casing.

Further, described projection is bucking ladder structure, and the front surface of described bucking ladder structure is with respect to the upper surface tilt alpha degree of plastic casing, and α is between 40 °≤α≤45 °; The rear surface of described bucking ladder structure is with respect to the upper surface inclination β degree of plastic casing, and β is between 80 °≤β≤85 °.

Further, between described dustproof glass and described projection window, be lined with sponge.

The utility model has the advantage of: 1, be equipped with dustproof glass at projection window, make the camera lens can be by contamination by dust, equipment be not fragile, and drop shadow effect is better; 2, multiple signal receivers are installed on plastic casing, make signal range of receiving larger, also can prevent from damaging because of signal receiver the work that has influence on; 3, heat-resisting radiator window has been carried out to independent processing, made the projector shell cost of producing.

Embodiment

Refer to shown in Fig. 1 and Fig. 2, a kind of reflection-type projector shell of the utility model, comprises a plastic casing 1, dustproof glass 2, signal receiver 31, signal receiver 32 and heat-resisting radiator window 4; The upper surface of described plastic casing 1 has a bucking ladder structure 5, and the front surface 51 of this bucking ladder structure 5 is provided with a projection window 21, and the side surface of described plastic casing 1 is also provided with a thermal window 41; Described dustproof glass 2 is laid on described projection window 21, and is lined with one deck sponge between dustproof glass 2 and projection window 21, for preventing dust better or preventing that glass from breaking because vibrating; Described heat-resisting radiator window 4 by independent machine-shaping after, be located in described thermal window 41, and this heat-resisting radiator window 4 for example adopts, higher than the resin material of set point of temperature (100 degrees Celsius) and makes; Described signal receiver 31 is positioned at the front surface 51 of described bucking ladder structure 5, described signal receiver 32 is positioned at the rear surface 52 corresponding with described front surface 51, and the upper surface angle of described front surface 51 and plastic casing 1 is α (α is between 40 °≤α≤45 °), the upper surface angle of described rear surface 52 and plastic casing 1 is β (β is between 80 °≤β≤85 °).The present embodiment has only been described signal receiver 31 and signal receiver 32 for example, but the utility model is not limited to this, can be that multiple signal receivers are distributed on a surface simultaneously.

What as shown in Figure 3, this figure showed is the areal map that signal receiver receives remote signal.A signal receiver was only installed at the front surface 51 of bucking ladder structure 5 by projector in the past, so the remote controller signal scope that it can receive is just limited in α 1 scope, when after people goes to projector, remote controller signal just may be stopped and the machine that cannot be projected receives.Adopt the utility model also to install after signal receiver in the rear surface 52 of bucking ladder structure 5, the remote controller signal scope that projection function receives will expand between (α 1+ α 2), α 1 represents to be positioned at the remote controller signal scope that the signal receiver of front surface 51 can receive, α 2 represents to be positioned at the remote controller signal scope that the signal receiver of rear surface 52 can receive, and this use that is us brings great convenience.

Although more than described embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art are in equivalent modification and the variation done according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
