Description
Technical field
The present invention relates to a kind of projecting apparatus, and in particular to a kind of durable meeting shadow equipment.
Background technology
Projecting apparatus is also known as projector, is by image or video by digital optical processing technique or LCD liquid crystal imagings technology
The equipment for projecting or reflexing on screen, can be by different signal sources, and such as computer, mobile phone, DVD, DV access are corresponding
Image and vision signal, realize and play.Projecting apparatus is widely used in the places such as education, commercial affairs, engineering, family expenses.
Projector is moving, extremely easily acted on by external force in transportation, produces strong concussion, macroseism can cause to throw
LCD panel in shadow machine produces displacement, three LCD convergence during influence projection, the misaligned phenomenon of RGB color occurs, and optics
Lens in system, speculum also can be deformed or damage, and influence image projection effect, and zoom lens can make under impact
Rail damage, causes camera lens stuck, or even camera lens rupture can not be used.
In addition, in the prior art, after we lift projector, often only noting the environment of surrounding, and hot-air is forgotten
The problem of rising, the projector worked on the ceiling, its environment temperature is generally greater than temperature below, and plus projection
The heat spreader that machine itself is produced is bad, the strong influence optical property and service life of projector lens.
The content of the invention
It is an object of the invention to provide a kind of durable meeting shadow equipment, solve projecting apparatus of the prior art by
Internal components are easy to deformation or damaged during macroseism, the problem of influenceing image projection effect；Solve to be arranged on day in the prior art
Projector on card is chronically in hot environment, bad, the problem of its service life is affected of radiating.
The present invention is achieved through the following technical solutions：
A kind of durable meeting shadow equipment, including projector body, the projector body are a cuboid, in projector
A rectangular protecting frame, in addition to 8 damping springs, one end of the damping spring and the corner of projector body are cased with outside body
The interior angle of fixed, another side and rectangular protecting frame is fixed, and 8 damping springs are in a center of symmetry on the center of gravity of projector body；
Rectangular protecting frame bottom is additionally provided with a deep bead, and the deep bead caves inward to form arc away from the side of rectangular protecting frame
Shape face, the both sides of the projector body, which are also provided with thermovent, the thermovent, is provided with fin, the two of rectangular protecting frame
Side is also respectively provided with a fan, and the fan is symmetrical on the perpendicular bisector of two thermovent central point lines.
The present invention devises a kind of new projecting apparatus, and the projecting apparatus includes projector body and rectangular protecting frame, in projector
8 damping springs, 8 damping springs 8 corners respectively with projector body, rectangle protection are set between body and rectangular protecting frame
8 interior angles of frame, which are corresponded, to be fixed, and forms a centrosymmetric structure, projector body is limited in rectangular protecting frame with this
Between.When projecting apparatus is by strong concussion, if some or several damping springs are produced deformation by the effect of impact, lead
Projector body is caused to be subjected to displacement, then one or more damping springs positioned at projector body opposite side can also be produced one by compression
Individual reaction force makes projector body towards the opposite direction motion being subjected to displacement, and reaches the mesh for making projector body keep balance and stability
, projecting apparatus of the prior art is solved with this and is easy to deformation or damage by internal components during macroseism, influence image is thrown
The problem of shadow effect.
One deep bead is set in the bottom of rectangular protecting frame again, the bottom of deep bead is set to an arc groove
Shape, so beneath hot-air are contacted after rising with the arcwall face of deep bead, then barrier effect of the hot-air by arcwall face
Arcuately the oblique moved beneath in face, thus is avoided that projector body is influenceed by the hot-air risen.Fin absorbs projector
The heat of body, a fan is also respectively provided with the both sides of rectangular protecting frame, the fan is on two thermovent central points
The perpendicular bisector of line is symmetrical, and two fans are worked simultaneously, and effectively fin can be cooled, and solving projector body with this dissipates
Hot bad, the problem of service life is affected.
It is preferred that, the lifting arm being connected with ceiling is additionally provided with the top of rectangular protecting frame, is provided with lifting arm
Infrared remote receiver, controller, motor, the motor are connected with lifting arm, wherein：
Infrared remote receiver：Receiving infrared-ray signal, and infrared signal is transferred to controller；
Controller：The infrared signal of infrared remote receiver transmission is received, and is sent infrared signal as trigger signal
Driving instruction is to motor；
Motor：The driving instruction that controller is sent is received, driving lifting arm vertically rises or falls.Enter one
Step, the middle arm of prior art is designed as liftable structure by the present invention, can easily adjust projector with respect to projection wall
Position, controller by the use of infrared signal as trigger signal send driving instruction to motor, people can be used infrared
Remote control is controlled it, convenient and practical, very with hommization.
The present invention compared with prior art, has the following advantages and advantages：
A kind of durable meeting shadow equipment of the present invention, sets 8 damping bullets between projector body and rectangular protecting frame
Spring, 8 damping springs 8 corners respectively with projector body, 8 interior angles of rectangular protecting frame are corresponded and fixed, and form one
Individual centrosymmetric structure, can make projector body keep balance and stability, projecting apparatus of the prior art is solved by macroseism with this
When internal components be easy to deformation or damage, influence image projection effect the problem of；Stop hot-air, two wind using deep bead
Fan works simultaneously, effectively fin can be cooled, solving existing arm hanging type projector with this is chronically at high temperature
In environment, bad, the problem of its service life is affected of radiating.
