Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of adjustable projector 10, including variola
Plate 1, the bottom of ceiling 1 is connected by electric lifting rod 2 is fixing with the top of rocking equipment 3, permissible by electric lifting rod 2
Adjusting the upper-lower position of projector 10, the bottom of electric lifting rod 2 is in the center of rocking equipment 3, and the inside of rocking equipment 3 sets
Being equipped with the chute 15 suitable with scroll wheel 12, the top of rocking equipment 3 is provided with one layer of anti-gray film, by anti-gray film can in case
Only dust enters rocking equipment 3 inside, it is ensured that rocking equipment 3 more efficient being operated of energy, passes through at the axle center of scroll wheel 12
Welding block 11 is fixing with the top of projector 10 to be connected, and projector 10 and movable pulley can be made to connect by welding block 11 more firm,
The both sides of projector 10 are flexibly connected with the first pulley 14 and the second pulley 7, by the first pulley 14 and second by transmission rope 9
