Description
Technical field
The present invention relates to projector equipment field, more particularly to a kind of projection angle are easy to adjust and with camera lens dustproof construction
Projector.
Background technology
Projector, also known as scialyscope, be a kind of can be by image or VIDEO PROJECTION to the equipment on curtain, can be by not
The same computer of same interface, VCD, DVD, BD, game machine, DV etc. are connected and play corresponding video signal.Projector extensively should
For family, office, school and public place of entertainment, according to working method difference, there are CRT, LCD, DLP etc. dissimilar.Projection
Instrument mounting means is divided into that desktop is just thrown, furred ceiling is just thrown, desktop rear-projection, furred ceiling rear-projection.Just throwing is scialyscope and spectators in side;The back of the body
Throwing is scialyscope with spectators respectively at screen two ends.If interim use, optional desktop furred ceiling mode.If space is larger,
There is overall arrangement during civil engineering, select rear-projection mode whole structure best, such as space is less, the method for optional rear-projection refraction.
When using furred ceiling, just the mode of throwing is installed, projector is fixedly connected by screw with suspension rod, the projector after installation
Position, deflection angle, angle of inclination cannot all change.In theory, picture accurate can be projected by the projector after installation
On shadow curtain, but the picture of practical situation often occurs certain skew, is unfavorable for viewing.Also, the throwing after being fixedly connected
The dismounting of shadow instrument is very inconvenient, and disassembly and assembly time is long, and during dismounting, projector is easily damaged.
At present, the projector in the multimedia Room (or classroom) be typically all be fixed on away from ground higher where, camera lens lead to
It is all often that the exposed dust outside, being accumulated on camera lens of long-time directly affects projector projects effect.In existing projector,
Had is covered camera lens using lens cap, it is to avoid dust pollutes.But this lens cap can only stop portions dust, thinner dust
Inside camera lens, therefore granule still can invade, and dust-proof effect is poor.Also, as projector is in higher position, the tearing open of lens cap
Fill very inconvenient.Lens cap easily falls, and after lens cap drops, camera lens still must be arrived dust-proof process.
Content of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of position of projected picture freely can adjust accurate positioning,
There is the projector for being cleaned automatically dust-proof structure to camera lens.
For solving above-mentioned technical problem, the present invention is employed the following technical solutions：
A kind of easy to adjust and projector with camera lens dustproof construction of projection angle, including body, is provided with camera lens on body,
Body top is provided with rotary head, and the turning end of rotary head is hinged with suspension rod, and it is scalable that body top is also hinged with 1-4 root
Pole, the other end per root pole is all hinged with fixed cover, and fixed cover is socketed on suspension rod；Dust cover is provided with camera lens,
One end of dust cover and the frame articulation of camera lens；Dedusting fan is installed on dust cover, dedusting fan is electrically connected with the circuit of body
Connect, on dust cover, be additionally provided with some dedusting holes.
Used as the preferred version of the present invention, the pole includes rotating bar and expansion link, and one end of rotating bar is articulated with machine
On body, the other end of rotating bar and the scalable connection in one end of expansion link, the other end of expansion link is hinged with fixed cover.
Used as the preferred version of the present invention, the fixed cover is made up of two semicircular rubber rings, one of rubber
The end of circle is provided with pin thread, and the end of another rubber ring is provided with box.
Used as the preferred version of the present invention, the radical of the pole is 4.
