Consult Fig. 6-1 and Fig. 6-2, in the present invention one specific embodiment: d-cinema projectors 31 is arranged on bikini support adjustment mechanism 32, bikini support adjustment mechanism 32 connects, in order to adapt to the projection demand of different movie theatre with additional support arm 33 again.
Consulting Fig. 7, is another mode of execution of the present invention.Be that bikini support adjustment mechanism 41 and additional support arm 42 connect equally, this mode is applicable to lays demand to the lifting of projector.
Fig. 6-1 with embodiment illustrated in fig. 7 in: the side on support arm (33,42) is provided with for vertical adjustment assembly hard-wired support platform 34, in order to guarantee that overall structure has enough rigidity.
The bikini support adjustment mechanism that the present invention is used for d-cinema projectors is also furnished with projector safety protection device; as shown in fig. 1; it is a safety rope bolt in the present embodiment; be arranged on flat bracket 11 or on support arm by two type rings and wire rope; be used for flat bracket 11 and support arm to carry out additonal limit (shown in Fig. 6-1 and Fig. 7), to strengthen reliable connection when system works.
Working principle of the present invention is:
Consult Fig. 4, when d-cinema projectors needs to adjust, adjusting knob 51 on the left of the system that turns clockwise, vertical leading screw 52 fixing with it rotates thereupon, and then drive upright slide block 53 to move upward, and then move up with the cross sliding clock 54 that upright slide block 53 connects, now the bulb of intermediate support assembly and then rotates, the effect that the flat bracket 55 finally reaching left side moves up.The adjustment on right side is similar.When the upright slide block location dimension of both sides is held in phase co-altitude, is then the pure luffing angle adjustment to projector, when the upright slide block position height as both sides is different, then reaches the additional effect reversing adjustment.
Accompanying drawings 4, when needing the angle adjusting horizontal nutation, turn to the inside adjusting handle 61, and handwheel moves right on horizontal screw lead 62, and then drive right side ball cup 63 to move simultaneously.The support block 64 adjacent with ball cup moves thereupon, and now the bulb of intermediate support assembly and then rotates, and finally reaches the effect that flat bracket 65 is swung to the right.When flat bracket 65 swings, support pressing plate 66 and guide runner 67 form sliding bearing pair to move, thus ensure the accurate of adjustment and lubrication.Locked by lock screw 68 after adjusting to the right place.
Left and right sides of the present invention vertically adjusts assembly and by-level adjustment assembly and can realize multi-direction, multi-freedom degree and adjust simultaneously, and mutual noninterference, the screw structure of employing can ensure the highi degree of accuracy of adjustment and the convenience of hand operation.
Above-mentioned case study on implementation can in addition some changes under not departing from the scope of the present invention, thus above illustrate in institute to comprise and the structure shown in accompanying drawing should be considered as exemplary, and be not used to the protection domain of restriction the present patent application patent.
