117 be provided above outer access port 119, outer access port 119 includes USB interface and power interface.
Additionally, see Fig. 1 and Fig. 3, in the present embodiment, the bottom of projector main body 110 is provided with tread plate 118, anti-skidding
Bar 118 is arc, and protrudes from the bottom of projector main body 110, owing to the projector main body 110 in the present embodiment is square
Structure, is square bottom it, and this tread plate 118 is arranged at four angles of bottom, and curved design.Tread plate 118
Arrange, it is simple to place projector main body 110, and projector main body 110 can be effectively prevented slide, it is ensured that projector main body 110
Stability, drop shadow effect is more preferable.
Designer of the present utility model finds under study for action, and the design of existing dustproof device for projector is the most ingenious, easily exists
Because dust affects drop shadow effect after using a period of time so that it is projection imaging is unintelligible, needs periodic maintenance to clear up, but light
Machine 111 and projection light source 112 are the core components of projector, the most fragile, often safeguard and are easy to cause damage it.
In order to solve this difficult problem of prior art, designer of the present utility model is when designing dust-proof projector 100, excellent
Change the dustproof construction of projector main body 110.
Specifically, see Fig. 1, realize dust reduction capability, this enforcement by the dust excluding plate 120 being connected with projector main body 110
Dust excluding plate 120 in example is used for covering or open the first through hole 113 and the second through hole 114, due to ray machine 111 and projection light source
112 stretch out the first through hole 113 and the second through hole 114 respectively, when dust excluding plate 120 covers the first through hole 113 and the second through hole 114
Time, i.e. it is blinded by ray machine 111 and projection light source 112, by utilizing dust excluding plate 120 to cover ray machine 111 and projection light source 112, has
The dust preventing to effect the external world enters ray machine 111 and projection light source 112, is conducive to protection ray machine 111 and projection light source 112.
Dust excluding plate 120 is by realizing covering or opening the first through hole 113 and the second through hole with the connection of projector main body 110
114, wherein, dust excluding plate 120, by having multiple with the connected mode of projector main body 110, such as, is slidably connected, is rotationally connected
Or removably connect.
Seeing Fig. 1 and Fig. 4, in the present embodiment, preferably dust excluding plate 120 is slidably connected with projector main body 110, by sliding
Connect realization cover or open the first through hole 113 and the second through hole 114.Specifically, by arranging cunning on projector main body 110
Dynamic groove 121, arranges protruding 122, protruding 122 on dust excluding plate 120 and is embedded in sliding tray 121, and slide even with sliding tray 121
Connect.
Owing to the projector main body 110 in the present embodiment is cube structure, projector main body 110 be positioned at the first through hole
113 and second the face at through hole 114 place be square structure, in the present embodiment, sliding tray 121 is arranged at the both sides in this face, and
Sliding tray 121 slides up and down.Wherein, the area of dust excluding plate 120 be projector main body 110 be positioned at the first through hole 113 and second
The 1/2 of the face area at through hole 114 place, ray machine 111 and projection light source 112 are positioned at the top half in this face, and dust excluding plate 120 is being slided
During Dong, during when dust excluding plate 120 upward sliding and with the top contact in this face, dust excluding plate 120 covers ray machine 111 and projected light
Source 112；When dust excluding plate 120 slide downward and contacting with the bottom in this face, dust excluding plate 120 opens ray machine 111 and projection light source
112。
When dust excluding plate 120 slides into the bottom in this face, it can be resisted against on projector main body 110, but work as dust excluding plate
120 upward slidings and during with the top contact in this face, need to position it, it is to avoid dust excluding plate 120 under gravity to
Lower slider.In the present embodiment, by arranging locating slot 123 on dust excluding plate 120, sliding tray 121 arranges locating piece 124,
When dust excluding plate 120 covers ray machine 111 and projection light source 112, hole, location coordinates with locating slot 123.Locating piece 124 and locating slot
Dust excluding plate 120 can be fixed on projector main body 110 by the cooperation of 123, thus avoids the slip of dust excluding plate 120.
Seeing Fig. 1 and Fig. 2, hand-strap 130 is connected with projector main body 110, it is simple to moves or carries projector main body
110, in the present embodiment, hand-strap 130 is strip or banded structure, and both sides with projector main body 110 respectively, its two ends are fixed
Connect, and be respectively arranged with fixing hole (not shown) at the two ends of hand-strap 130, projector main body 110 is provided with circle
Flange 131, this flange 131 protrudes from projector main body 110, install hand-strap 130 time, fixing hole is fastened on flange
In gap between 131 and projector main body 110, thus play the effect of fixing hand-strap 130.The top of projector main body 110
And there is certain gap between hand-strap 130, when moving or carrying projector main body 110, hands can be stretched into this by user
Gap, it is simple to grasp hand-strap 130.Projector main body 110 can also be hung and project by hand-strap 130 simultaneously, widens
The range of dust-proof projector 100 and occupation mode.
Seeing Fig. 1, the operation principle of dust-proof projector 100 is: when dust-proof projector 100 operationally, by dust excluding plate 120
Slide downward, opens the first through hole 113 and the second through hole 114, it is simple to ray machine 111 and projection light source 112 project, and when dust-proof throwing
When shadow instrument 100 does not works, by dust excluding plate 120 upward sliding, cover the first through hole 113 and the second through hole 114, thus cover ray machine
111 and projection light source 112, it is to avoid extraneous dust enters ray machine 111 and projection light source 112.Owing to, in the present embodiment, first leads to
Hole 113 is disposed on projecting the bottom of concave surface 115, and the second through hole 114 is arranged at the bottom of light source concave surface 116, and projects recessed
Face 115 tilts towards the first through hole 113, and light source concave surface 116 tilts towards the second through hole 114.Projection concave surface 115 and light source concave surface
116 not only can spread ray machine 111 and the light of projection light source 112, and projection concave surface 115 and light source concave surface 116 can simultaneously
The dust preventing top falls in ray machine 111 and projection light source 112, meanwhile, and projection concave surface 115 and the inclining of light source concave surface 116
Tiltedly the dust landing in setting, beneficially ray machine 111 and projection light source 112, is effectively prevented from the dust impact on drop shadow effect.
In sum, ray machine 111 of the present utility model and projection light source 112 are led to by stretching out the first through hole 113 and second
Hole 114 projects, when not using projector, when utilizing dust excluding plate 120 to cover the first through hole 113 and the second through hole 114, i.e.
Being blinded by ray machine 111 and projection light source 112, arranging of dust excluding plate 120 can be effectively prevented from dust entrance or be deposited in ray machine 111
With in projection light source 112, thus reduce ray machine 111 and the maintenance of projection light source 112 or cleaning frequency, improve ray machine 111 He
In the service life of projection light source 112, additionally, free from dust is piled up in ray machine 111 and projection light source 112, be conducive to improving dust-proof throwing
The drop shadow effect of shadow instrument 100.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle
Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
