Description
Technical field
The present invention relates to the required double-projector hanger of a kind of passive tridimensional virtual reality optical projection system, specifically is a kind of double-projector hanger of can Three Degree Of Freedom independently adjusting.
Background technology
Existing projector hanger can only be that separate unit projector uses mostly, can't satisfy the requirement that the required dual-projection machine of passive tridimensional virtual reality optical projection system is independently adjusted pitching, yaw, side tilt angle.Even the projector hanger that has can satisfy the installation requirement of the required dual-projection machine of passive tridimensional virtual reality optical projection system, but its pitching, side tilt angle are to lean on the nut position of adjusting on two screw rods of projector installing plate front to adjust.Because screw rod is connected on the upper and lower crossbeam of suspension bracket, rigidity is very big, so the adjustable angle scope of projector's installing plate is very little, and generation is stuck easily in the adjustment process, uses extremely inconvenient.
Summary of the invention
The purpose of this invention is to provide a kind ofly can overcome above-mentioned defective, realize the angle of pitch, side rake angle, yaw angle Three Degree Of Freedom independently adjust, make two projection functions accurate double-projector hanger of just batching.Its technical scheme is:
Comprise length-adjustable suspension rod, suspension bracket frame, back vertical plate, ball pivot and two install adjustment mechanisms of cover projector; Wherein the suspension bracket frame is fixed on the suspension rod bottom; Back vertical plate is vertically fixed on the centre position of suspension bracket frame back, and every cover install adjustment mechanism includes a projector and decides plate and be positioned at the adjusting screw(rod) assembly that projector decide the plate both sides, it is characterized in that: overlapping install adjustment mechanism with one is example; Projector decides plate and is connected with back vertical plate through ball pivot; It is hinged with an end of adjusting screw(rod) assembly respectively that projector decides the front end of plate both sides, and the other end of two adjusting screw(rod) assemblies is hinged with the suspension bracket frame column that is positioned at the back vertical plate both sides respectively, sets up the motor-driven plate of projection; The same circumference of the motor-driven plate of projection is provided with four bolts hole; Corresponding with it, the same circumference that projector decides plate is provided with four guide grooves, and the motor-driven plate of projection is fixed on the bottom that projector decides plate through bolt passing through bolt hole and guide groove; Each adjusting screw(rod) assembly includes the top nut sleeve, is provided with the bolt and the lower nut sleeve of set nut; Wherein the thread rotary orientation at bolt two ends is opposite; The corresponding screw-in in top nut sleeve and the lower nut sleeve; It is hinged that the top of top nut sleeve and projector decide plate, and the bottom of lower nut sleeve and suspension bracket frame column are hinged.
Described double-projector hanger, four bolts hole are separately positioned on four angles of the motor-driven plate of projection.
Principle of work is:
Adjustment projector yaw angle: unclamp and connect the coupling bolt that the motor-driven plate of projection and projector decide plate, the motor-driven plate of rotation projection is waited to adjust the yaw angle and by bolt the motor-driven plate of projection and projector is decided plate again and fix.
The adjustment projector angle of pitch: unclamp the set nut in the adjusting screw(rod) assembly, rotating bolt can be adjusted the length of adjusting screw(rod) assembly, and then the luffing angle of adjustment projector, and adjustment finishes, and tightens set nut, fixedly the luffing angle of projector.
Adjustment projector side tilt angle; Unclamp set nut, the adjusting bolt of reverse rotation both sides can reduce or increase opposite side adjusting screw(rod) assembly length when increasing or reducing a side adjusting screw(rod) assembly length; And then the side tilt angle of adjustment projector; Adjustment finishes, and tightens set nut, can fix the side tilt angle of projector up and down.
The present invention compared with prior art, its advantage is:
1, the dual-projection machine that can realize passive tridimensional virtual reality system carries out the angle of pitch, side rake angle, yaw angle Three Degree Of Freedom respectively and independently adjusts; Make two projection functions accurate projector hanger of just batching; Thereby accurately adjust the projection angle of projector; Make projector fully just throw aligning, improve projection quality and effect.
2, use three ball pivots fixedly projector decide plate, guaranteed that it is a plane all the time that projector decides plate, warpage and the distortion of having avoided interference and projector in the adjustment process to decide plate.
3, simple in structure, reliable, easy to use, standardization processing, installation and maintenance simple and fast.
