Description
Technical field
This utility model relate to a kind of adjustment device, has been specifically related to a kind of projector holding device.
Background technology
Projector, also known as scialyscope, be a kind of can by the equipment on image or VIDEO PROJECTION to curtain, it is possible to be connected the corresponding video signal of broadcasting by the different same computers of interface, VCD, DVD, BD, game machine, DV etc..Projector is widely used in family, office, school and public place of entertainment, different according to working method, has CRT, LCD, DLP etc. dissimilar.
In the past in school's multi-media classroom, projector can be installed, projector is typically mounted at wall top, a projector controlled expansion link installed above, expansion link is fixedly connected on wall, after installing projector, need again installation curtain on the wall at dais, the installation site of curtain needs the position according to projector to determine, but often due to install deviation, the side as relatively curtain that projector is launched on curtain can be made, 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 distort, thus affecting quality of instruction.
Utility model content
This utility model is intended to provide a kind of projector holding device making imaging coordinate.
Projector holding device in this programme, it is arranged on wall, including expansion link, wall is provided with chute, expansion link is arranged over the chute being fixed in wall, slide block is slidably connected in chute, expansion link is fixedly connected on slide block, gripper shoe is slidably connected between the two side of chute, expansion link run through gripper shoe and with gripper shoe matched in clearance, gripper shoe is connected with base, base is slidably connected on chute wall, base is hinged with crank, the free end of crank is hinged with connecting rod, connecting rod is hinged with jacking block, jacking block is through gripper shoe and is slidably connected on the supporting plate.
The know-why of this programme and have the beneficial effect that and open projector, adjustable telescopic rod, make projector imaging 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 regulating the left and right position of projector, so that the left and right position that projector is on curtain is coordinated；After adjusting position, rotating crank, crank handle turns connecting rod swing, connecting rod drives jacking block to move upward, gripper shoe is motionless, jacking block moves to and shoe contact always, is rotated further crank, and jacking block will hold out against slide block, hold out against bottom slide block and chute, slide block is made more to be stably fixed to the position being suitable for, so that slide block is not susceptible to mobile, it is ensured that imaging left and right position is coordinated.
Further, slide block is connected to cylinder.The setting of cylinder, facilitates the adjustment in the left and right direction of slide block.
Further, jacking block, base, crank and connecting rod are two, and two jacking blocks, base, crank and connecting rod are all symmetrically disposed about with expansion link.Rotating two cranks, two connecting rods of two crank handle turns drive together, and two connecting rods drive two jacking blocks to move upward, and two jacking blocks hold out against slide block symmetrically so that slide block is more uniformly stressed, and enhances and holds out against effect.
Further, two cranks are respectively connected with motor.Two motors of synchronous averaging, the rotation that two motor controlled yeast production handles are random, thus facilitating the control of crank.
Further, two jacking block tops are respectively connected with block rubber.Block rubber has elasticity, and the second jacking block drives block rubber to hold out against slide block, and block rubber is by flexible deformation so that holds out against more firm, further increases the stability of slide block.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model projector holding device embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: chute 1, slide block 2, gripper shoe 3, base 4, crank 5, connecting rod 6, expansion link 7, block rubber 8.
nullEmbodiment is basic with reference to shown in Fig. 1: projector holding device，It is arranged on wall，Including expansion link 7，Expansion link 7 is arranged over the chute 1 being fixed in wall，Slide block 2 is slidably connected in chute 1，The front end of chute 1 inner slide 2 movement locus is provided with cylinder，Slide block 2 is connected on cylinder，Expansion link 7 is welded on slide block 2，Gripper shoe 3 is slidably connected between the two side of chute 1，Expansion link 7 through gripper shoe 3 and with gripper shoe 3 matched in clearance，Gripper shoe 3 is connected with two bases 4 symmetrical centered by expansion link 7，Two bases 4 are slidably connected at a left side for chute 1、On right side wall，Two bases 4 are all hinged with crank 5，Two cranks 5 are all hinged with connecting rod 6，Two connecting rods 6 are all hinged with jacking block，Two jacking blocks both pass through gripper shoe 3 and are slidably connected in gripper shoe 3，The top of two jacking blocks is bonded with block rubber 8，Two cranks 5 are respectively connected with motor，Two motors are slidably connected on chute 1 wall.
Start cylinder, the left and right slip of cylinder band movable slider 2, slide block 2 drives expansion link 7 to move, expansion link 7 drives the left and right motion of gripper shoe 3, gripper shoe 3 drives jacking block to move together, base 4, crank 5 interlock together with jacking block with connecting rod 6, after adjusting left and right position, start two motors, two motor in synchrony drive two connecting rods 6 to be swung up, two connecting rods 6 drive two jacking blocks upward sliding in gripper shoe 3, and two jacking blocks drive two block rubbers 8 to move upward, and slide block 2 is held out against by two block rubbers 8.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
