Abstract

A projector shell is composed of an upper cover and a lower cover made of aluminum materials. A view screen projection port, a first element arrangement frame, a second element arrangement frame, a third element arrangement frame and four studs are arranged on the back face of the upper cover, seven first screw holes are formed along the edge of the back face of the upper cover, and three fixing grooves are formed along the edge wall of the back face of the upper cover. Seven second screw holes are formed along the edge of the lower cover, three fixing blocks are arranged at the edge of the lower cover, a projection port arrangement groove is formed in the edge wall of the lower cover, and a fourth element arrangement frame is arranged at the bottom of the lower cover. The projector shell is made of the aluminum materials, so that the heat dissipation effect is good, and good application effects are maintained. The element arrangement frames of the projector shell are reasonable in layout, the component structure is precise, the shakeproof effect is quite good after electronic elements are correspondingly installed, and good application effects are further maintained.

Description

A kind of projector shell

Technical field

The invention belongs to a kind of novel machine casing, be specifically related to a kind of projector shell.

Technical background

Projector, also known as projector, be a kind of can by image or VIDEO PROJECTION to the equipment on curtain, same to computing machine, VCD, DVD, BD, game machine, DV etc. can be connected and play corresponding vision signal by different interfaces.Projector is widely used in family, office, school and public place of entertainment, and different according to working method, have CRT, LCD, DLP etc. are dissimilar.

Optical system notes the dust-proof of environment for use and ventilation and heat.The polysilicon LCD plate of projector is all compare fearness high temperature, newer type is all equipped with temperature sensor near LCD plate, when air inlet and dirt filtrating screen blocked, when air-flow is smooth, projection built-in temperature can raise rapidly, and at this moment temperature sensor can be reported to the police and be cut off lamp source circuit immediately.And generally have special fan to carry out air-supply cooling with the flow of tens litres of air per minute to it because projector LCD plate fully dispels the heat, high velocity air also likely carries small dust secretly after dirt filtrating screen, they mutually rub and produce electrostatic and be adsorbed in cooling system, and this will have an impact to projected picture.Therefore, dust-proof extremely important in projector's environment for use, must absolutely no smoking, because smokeshade is more easily adsorbed in optical system.Therefore dirt filtrating screen that is frequent or periodic cleaning air inlet is wanted.So, keep the unimpeded of air inlet.

Meanwhile, when projector mechanical aspects is strictly on guard against strong collision, extruding and vibrations.Because macroseism can cause the displacement of LCD panel, the convergence of three LCD during impact projection, there is the phenomenon that RGB color does not overlap, and the lens in optical system, catoptron also can produce distortion or damage, and effect diagram is as drop shadow effect, and zoom lens can make rail damage under impact, cause camera lens stuck, even camera lens breaks and cannot use.

How many current projector, because the reason such as shell mechanism and constituent material, all can be subject to the impact of above-mentioned factor.

Summary of the invention

Object of the present invention is just to provide brand-new a kind of projector shell.Specifically comprise: this shell is made up of upper cover and lower cover, and this shell makes of aluminium.

The present invention is achieved through the following technical solutions:

1, a projector shell, is in technical scheme: this shell is made up of upper cover (1) and lower cover (2).

Described upper cover (1) is one piece of plate face, the reverse side of upper cover (1) is provided with screen projection mouth (3), component positioning frame one (4), component positioning frame (5), component positioning frame three (6), four studs (7), its edge of reverse side along upper cover (1) is provided with seven screws one (8), and its limit wall of reverse side along upper cover (1) is provided with three fixed grooves (9).

Described lower cover (2) is a box body, edge along lower cover (2) is provided with seven screws two (10), the edge of lower cover (2) is provided with three fixed blocks (11), the limit wall of lower cover (2) is provided with projection mouth resettlement groove (12), the bottom of lower cover (2) is provided with component positioning frame four (13).

When above-mentioned upper cover (1) and lower cover (2) combination, be by the reverse side closing lid of upper cover (1) on lower cover (2), making the screen of upper cover (1) project mouth (3) during closing lid is placed in the projection mouth resettlement groove (12) that lower cover (2) limit wall is provided with, three fixed blocks (11) that three fixed groove (9) alignment lower cover (2) edges that upper cover (1) Bian Bisuo is provided with are provided with, seven screws two (10) that seven screws one (8) alignment lower cover (2) edge that upper cover (1) edge is provided with is provided with, and tighten with screw, form a projector shell entirety thus.

2, a projector shell, is in technical scheme: this shell makes of aluminium.

Tool of the present invention has the following advantages:

1, its structure of the present invention composition design science is reasonable.

2, traditional projector is in overheated hot environment, and return and make some element function of electronic product inside unstable, the function directly affecting product uses.The present invention makes of aluminium, and radiating effect is very good, keeps the effect of high-quality.

3, in the present invention, each component positioning frame is rationally distributed, and modular construction is accurate, and after electronic component correspondence is installed, shockproof effect is good especially, keeps the effect of high-quality.
