Description
Technical field
The present invention relates to a kind of regulating device for projector.
Background technology
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.
In the past in school's multi-media classroom, projector can be installed, projector is generally arranged on wall top, the expansion link that above projector, installation one is controlled, expansion link is fixedly connected on wall, after installing projector, need again, on the wall at dais, curtain is installed, the installation site of curtain needs to determine according to the position of projector, but the deviation often owing to installing, a side of curtain is partial to by the picture that projector can be made to launch on curtain, and on, lower direction can be regulated by expansion link, projector is left, right direction but can not regulate, cause into the picture gone out left, right direction is inharmonious, or make imaging distortion, thus affect quality of instruction.
Summary of the invention
The invention is intended to provide a kind of regulating device for projector that imaging is coordinated.
The regulating device for projector in this programme, be arranged on wall, comprise expansion link, wall is provided with chute, slide block is slidably connected in chute, expansion link is fixedly connected on slide block, slidably connects back up pad between the two side of chute, expansion link run through back up pad and with back up pad clearance fit, connecting rod is slidably connected on the downside of back up pad, connecting rod is fixedly connected with the first voussoir, the first voussoir has the second voussoir mutually, the second voussoir passes back up pad and is slidably connected with back up pad.
The know-why of this programme and beneficial effect are: open projector, adjustable telescopic rod, make the imaging of projector on curtain, upper and lower position is coordinated, then sliding slider, slide block drives the left and right motion of expansion link, and expansion link drives the left and right motion of projector, thus regulate the left and right position of projector, coordinate to make the left and right position of projector on curtain; After adjusting position, pull connecting rod, connecting rod drives the first wedge block movement, and drive second voussoir moves upward by the first voussoir, back up pad is motionless, and move to and shoe contact, pull connecting rod continuously, the second voussoir will hold out against slide block; always hold out against bottom slide block and chute, make slide block more stable be fixed on suitable position, thus slide block is not easily moved, ensure that imaging left and right position is coordinated.
Further, one end of chute inner slide movement locus is provided with the first cylinder, and slide block is connected on the first cylinder.The setting of the first cylinder, facilitates the adjustment in the left and right direction of slide block.
Further, the quantity of the first voussoir, the second voussoir is two, and two the first voussoirs are symmetricly set on connecting rod, and two the second voussoir symmetries are established on the supporting plate.Pull connecting rod, connecting rod drives two the first voussoirs to move together, and two the first voussoirs drive two the second voussoirs to move upward, and two the second voussoirs hold out against slide block symmetrically, makes slide block stressed more even, enhances and hold out against effect.
Further, the side of connecting rod is connected with the second cylinder, and the second cylinder slide is connected on chute.Start the second cylinder, the second cylinder can the left and right motion arbitrarily of control link, thus facilitates the control of connecting rod.
Further, two screw tip are all connected with block rubber through back up pad.Block rubber has elasticity, and the second voussoir drives block rubber to hold out against slide block, and block rubber, by flexible distortion, makes to hold out against more firm, further increases the stability of slide block.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the regulating device embodiment of projector.
