First fixing frame is aimed to camera and it is linked on camera, the bolt of tightening on fixing frame makes it hold out against camera; The position of adjusting slider on horizontal cross bar again, makes the clamping chamber of fixture aim at the top of projector for real object armed lever, finally by the top of clamp projector for real object armed lever, is about to equipment of the present utility model and is installed on projector for real object.
In the time need to regulating the angle of camera, the angle of setting by the human-computer interaction interface input on steering engine controller, steering wheel automatically goes to this angle (attitude) and remains unchanged.When rotating, steering wheel drive driven gear to rotate along the bottom righthand side of Z-shaped bar by driving gear, driven gear and then the bottom righthand side axis along Z-shaped bar rotates by the montant drive horizontal cross bar affixed with it; Dead in line due to the camera of projector for real object and the center line of the hinge between armed lever and Z-type bar bottom righthand side, therefore the rotation of horizontal cross bar can drive fixing frame and camera along the hinge axis rotation of armed lever and camera, realizes the maintenance of camera and the rotation of steering wheel equal proportion and angle.
Compared with prior art, the beneficial effects of the utility model are:
One, the utility model drives montant to rotate along the bottom righthand side axis of Z-shaped bar by steering wheel, main driven gear, and and then the camera that drives projector for real object by cross bar, fixing frame along the camera hinge of the bottom righthand side dead in line with Z-shaped bar, rotate, thereby automatically, fine adjustment keep camera to the angle of setting,, its demonstration and teaching efficiency are good; Be particularly useful for the occasion that needs demonstration is demonstrated the thin portion of thing special angle.
Two, the utility model is clamped in the armed lever top of projector for real object and by fixing frame, is linked on the camera of projector for real object by fixture, can be installed on existing projector for real object, realize the function of automatic fine adjustment camera angle, and do not need the existing structure of projector for real object to do any change, be applicable to various projector for real object.
Further, the concrete formation of fixture of the present utility model is: the opposing side of two jaw middle and lower parts forms clamping chamber, and the top of two jaws coordinates with slide rail bottom, and the upper surface of slide rail forms fixture root; Jaw in two jaws is threaded with double rotational directions threaded stem one side, and another jaw is threaded with double rotational directions threaded stem opposite side, and the thread rotary orientation of double rotational directions threaded stem both sides is contrary; Described slide rail lower surface is fixedly connected with a positioning block by short montant, and the positioning hole of positioning block is linked on the smooth position at double rotational directions threaded stem middle part.
By rotation double rotational directions threaded stem, can make two jaws along slide rail generation move toward one another, clamp the top of armed lever; Counterrotating double rotational directions threaded stem can make two jaws opposing moving occur and unclamp armed lever along slide rail.Its clamping and convenient disassembly.And because double rotational directions threaded stem is linked in the positioning hole of positioning block, can guarantee that the vertical position of double rotational directions threaded stem and two jaws thereof is fixed.And then guaranteeing each dead in line that clamps the rear camera of projector for real object and the center line of the hinge between armed lever and Z-type bar bottom righthand side, two jaw V-type clamp faces can be determined the axis in clamping chamber automatically.
Further, fixing frame of the present utility model side is provided with gyroscope, and gyrostatic output terminal is connected with steering engine controller.
Gyroscope can accurately detect the angle between camera and horizontal plane, thereby facilitates the utility model to take the angular adjustment that horizontal plane is reference.
Further, steering engine controller of the present utility model is for receiving the controller of infrared remote-controlled signal.
Like this, can by remote controller, accurately control the camera angle of swing of projector for real object, be convenient to user and carry out Remote operation.
Below in conjunction with accompanying drawing and concrete mode of execution, the utility model is described in further detail.
