Embodiment
Following examples are used to illustrate the utility model, but are not limited to scope of the present utility model.
As shown in Figure 1-Figure 3, a kind of dynamoelectric projection instrument crane, including drive mechanism and fixed mechanism, the fixed machine
Structure is arranged on below drive mechanism and fixed mechanism is connected with drive mechanism；
The fixed mechanism includes two pieces of fixed plates 1, and two pieces of fixed plates 1 are horizontally disposed and are parallel to each other, two pieces of fixed plates 1
It is bolted；
The drive mechanism includes upper bracket 2, lower carriage 3, the first pole 4, the second pole 5 and electric expansion cylinder 9, described
Upper bracket 2 is located at the top of lower carriage 3, and the lower carriage 3 is fixed therein in one piece of fixed plate 1, the two ends of first pole 4
It is hinged respectively with upper bracket 2 and lower carriage 3, the two ends of second pole 5 are hinged with upper bracket 2 and lower carriage 3 respectively, described
First pole 4 and the second pole 5 are located at the both sides of electric expansion cylinder 9 respectively, and the afterbody of the electric expansion cylinder 9 is located at upper bracket 2
Place, one end of the second pole of afterbody 5 of the electric expansion cylinder 9 is hinged, and the head of the electric expansion cylinder 9 is located at lower carriage 3
Place, the head of the electric expansion cylinder 9 and one end of the first pole 4 are hinged
In fact, electric expansion cylinder 9 drives fixed mechanism with the afterbody of electric expansion cylinder 9 and the pin joint of the second pole 5
For the center of circle so that fixed mechanism makees movement in a curve, so as to reach the purpose of height of projector change.
Preferably, the control for length of being stretched for convenience to electric expansion cylinder 9, the electric expansion cylinder 9 is electronics electricity
Dynamic telescoping cylinder, the electric expansion cylinder 9 is provided with stroke sensor.
Fitted preferably, matching somebody with somebody to projecting apparatus realization power supply is also electrically connected with electric control, the drive mechanism for convenience
Orchestration 7, the upper bracket 2 is provided with socket, and the socket is electrically connected by stroke sensor switch with power supply adaptor 7.
Preferably, the first pole 4 and the second pole 5 rotate more smooth for convenience, first pole 4 and
Two poles 5 are hinged by bearing pin 6 with lower carriage 3.
Preferably, the scope of application in order to increase the host rack, adapts to the projecting apparatus of various gauge sizes, the fixation
Plate 1 be arranged in parallel provided with two bar holes 8, two bar holes 8.
When mounted, it is only necessary to which projecting apparatus is placed between two pieces of fixed plates 1, then according to the width of projecting apparatus, adjust
Position of the bolt in bar hole 8 is saved, fastening is then realized, bar hole 8 here is primarily to the throwing of matching various sizes
Shadow instrument and design.
And it is normal in use, user directly fixes upper bracket 2 on top at home, by controlling electric expansion cylinder
9 elongation or shortening, and then the rising or decline of projecting apparatus are realized, for example：Electric expansion cylinder 9 extends, electric expansion cylinder 9
Top will head on lower carriage 3 and move it is because the top of electric expansion cylinder 9 is hinged with one end of the first pole 4, i.e., electric
The top of dynamic telescoping cylinder 9 will head on the first pole 4 and the tie point of lower carriage 3 is moved up, and such total can just disappear
