Description

Projector adjustment tight-push unit
Technical field
The present invention relates to a kind of controlling device, be specifically related to a kind of projector adjustment tight-push unit.
Background technique
Projector, also known as projector, be a kind of can by image or VIDEO PROJECTION to the equipment on curtain, same to computer, VCD, DVD, BD, gaming machine, DV etc. can be connected and play corresponding video signal by different interfaces.Projector is widely used in family, office, school and entertainment places, 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 flexible rod that above projector, installation one is controlled, flexible rod is fixedly connected on wall, after installing projector, need again, on the wall at dais, curtain is installed, the mounting point 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 flexible rod, 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 projector adjustment tight-push unit that imaging is coordinated.
Projector adjustment tight-push unit in this programme, be arranged on wall, comprise flexible rod, wall is provided with chute, the chute be fixed in wall is provided with above flexible rod, slide block is slidably connected in chute, flexible rod is fixedly connected on slide block, dunnage is slidably connected between the two side of chute, flexible rod run through dunnage and with dunnage Spielpassung, base is provided with below dunnage, base sliding is connected on chute wall, base is hinged with connecting rod, connecting rod is hinged with continuous motion stem, continuous motion stem is hinged with jacking block, jacking block passes dunnage and is slidably connected on the supporting plate, also comprise push rod, push rod is hinged with connecting rod, connecting rod, connecting rod and continuous motion stem are by same chain connection.
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 flexible rod, and flexible rod 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, upwardly push rod, push rod drives connecting rod upwards to swing, connecting rod promotes hinged place and moves to the direction away from push rod, connecting rod swing, continuous motion stem promotes jacking block and moves upward, and jacking block moves to and shoe contact always, continue to promote push rod, jacking block will hold out against slide block, 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, slide block is connected with the first cylinder.The setting of cylinder, facilitates the adjustment in the left and right direction of slide block.
Further, base, connecting rod, continuous motion stem, connecting rod and jacking block are two, and two bases, connecting rod, continuous motion stem, connecting rod and jacking blocks are all arranged symmetrically centered by flexible rod, and two connecting rods are all hinged on push rod.Rotating push-rod, push rod drives two connecting rods to move upward together, and two connecting rods drive hinged place to move to the direction away from push rod, connecting rod swing, continuous motion stem moves jacking block and moves upward, and two jacking blocks hold out against slide block symmetrically, make slide block stressed more even, enhance and hold out against effect.
Further, push rod is connected with the second cylinder, the second cylinder is fixedly connected between two bases.Start the second cylinder, the second cylinder can control the random upper and lower motion of push rod, thus facilitates the control of push rod.
Further, two jacking block tops are all connected with block rubber.Block rubber has elasticity, and jacking block 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.
