The utility model provides a double-projector hanging bracket comprising a length adjustable hanging rod, a hanging bracket frame, adjusting screw rod assemblies, a spherical hinge, a projector fixed plate and a rear vertical plate, wherein the hanging bracket frame is fixed at the bottom of the hanging rod; and the rear vertical plate is vertically fixed in the middle position of the rear part of the hanging bracket frame. The double-projector hanging bracket is characterized in that the projector fixed plate is connected with the rear vertical plate through the spherical hinge; the front ends at two sides of the projector fixed plate are respectively articulated with one end of the adjusting screw rod assemblies; the other ends of the two adjusting screw rod assemblies are respectively articulated with upright posts of the hanging bracket frame at two sides of the rear vertical plate; a projector movable plate is added; four bolt holes are arranged on the same circumference of the projector movable plate; correspondingly, four guide slots are arranged on the same circumference of the projector fixed plate; and the projector movable plate is fixed at the bottom of the projector fixed plate by the bolts passing through the bolt holes and the guide slots. The utility model has the advantages that the three rotating degrees of freedom of the two projectors can be independently and accurately adjusted, the complete orthographic projection and alignment of the projectors are realized, and the projection quality is improved.

Description

Double-projector hanger
Technical field
The utility model relates to the required double-projector hanger of a kind of passive tridimensional virtual reality projecting system, specifically is a kind of double-projector hanger of can Three Degree Of Freedom independently adjusting.
Background technique
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 projecting 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 projecting system, but its pitching, side tilt angle are to adjust through the nut position on two screw rods of projector mounting plate front by adjustment.Because screw rod is connected on the upper and lower crossbeam of suspension bracket, rigidity is very big, so the angle adjustable scope of projector's mounting plate is very little, and generation is stuck easily in the adjustment process, uses extremely inconvenient.
The model utility content
The purpose of this utility model provides a kind ofly can overcome above-mentioned defective, realize pitching angle, just the batching double-projector hanger of standard of two projection functions independently is adjusted, made to angle of heel, yaw angle Three Degree Of Freedom.Its technological scheme is:
Comprise length-adjustable suspension rod, the suspension bracket frame, the adjusting screw rod assembly, ball pivot, projector decides plate, back vertical plate, wherein the suspension bracket frame is fixed on the suspension rod bottom, back vertical plate is vertically fixed on the neutral position of suspension bracket frame back, it is characterized in that: projector decides plate and is connected with back vertical plate by ball pivot, it is hinged with an end of adjusting screw rod assembly respectively that projector decides the front end of plate both sides, 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, set 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.
Described double-projector hanger, each adjusting screw rod assembly includes the upper cap nut sleeve, is provided with the bolt and the lower nut sleeve of locking nut, wherein the thread rotary orientation at bolt two ends is opposite, the corresponding screw-in in upper cap nut sleeve and the lower nut sleeve, it is hinged that the top of upper cap 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.
Working principle is:
Adjust projector's yaw angle: unclamp and connect the connecting bolt that the motor-driven plate of projection and projector decide plate, the motor-driven plate of rotation projection, good yaw angle to be adjusted is decided plate by bolt with the motor-driven plate of projection and projector again and is fixed.
Adjust projector's pitching angle: unclamp the locking nut in the adjusting screw rod assembly, rotating bolt can be adjusted the length of adjusting screw rod assembly, and then adjusts the luffing angle of projector, and adjustment finishes, and tightens locking nut, fixedly the luffing angle of projector.
Adjust projector's side tilt angle, unclamp locking nut, the adjusting bolt of counterrotating both sides, can when increasing or reducing a side adjusting screw rod assembly length, reduce or increase opposite side adjusting screw rod assembly length, and then the side tilt angle of adjustment projector, adjustment finishes, and tightens locking nut, can fix the side tilt angle of projector up and down.
The utility model compared with prior art, its advantage is:
1, the dual-projection machine that can realize passive tridimensional virtual reality system carries out pitching angle, angle of heel, 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 phenomenon in the adjustment process and projector to decide plate.
3, simple in structure, reliable, easy to use, standardization processing, installation and maintenance simple and fast.
