Improve as one:
Described cross-brace frame is air spring structure, be provided with telescopic horizontal piston rod, the end of horizontal piston rod is provided with fixture, projector is arranged on fixture, and fixture is provided with draw ring, and draw ring is connected with bracing wire, bracing wire is connected with motor through holder, described motor is fixed on cabinet, and described motor is electrically connected with control panel, and control panel controls the rotating forward of motor, reversion and idle running; Control panel is electrically connected with projector, projection screen respectively.
As further improvement:
Described vertical supporting frame is air spring structure, and be provided with telescopic vertical piston rod, holder is arranged on the end of vertical piston rod, and holder is provided with pulley, and bracing wire is parallel with vertical supporting frame through pulley.
As further improving:
Described motor is provided with protective cover, and the bottom of control panel is rotatably installed on protective cover.
Be provided with the snap ring of fixing projection screen immediately below described projection screen, described snap ring is fixedly installed on cabinet.
Owing to have employed technique scheme, compared with prior art, the utility model has the following advantages:
(1), easy to use, during use, control Power Drive Unit, under the thrust of air spring, bracing frame is opened, and controls projector and projection screen and just can use; The not used time, control Power Drive Unit, under the traction of Power Drive Unit, air spring shrinks, and bracing frame is packed up, and equipment pushes away away;
(2), balance is strong, and after during use, bracing frame rises, balance device is opened automatically, keeps the stability of equipment, not easily damage equipment.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation

Embodiment
Embodiment: as shown in Figure 1, a kind of Mobile Teaching projector, comprise cabinet 1, the front end of described cabinet 1 is provided with angle sheave 2 rear end and is provided with road wheel 3, described cabinet 1 is fixed with vertical supporting frame 4, the end anchorage 6 of described vertical supporting frame 4, holder 6 is laterally provided with cross-brace frame 5, the end of described cross-brace frame 5 is provided with projector 8, and described holder 6 is provided with projection screen 9.
Described cross-brace frame 5 is air spring structure, be provided with telescopic horizontal piston rod 51, the end of horizontal piston rod 51 is provided with fixture 7, projector 8 is arranged on fixture 7, and fixture 7 is provided with draw ring, and draw ring is connected with bracing wire 10, bracing wire 10 is connected with motor 14 through holder 6, described motor 14 is fixed on cabinet 1, and described motor 14 is electrically connected with control panel 13, and control panel 13 controls the rotating forward of motor 14, reversion and idle running; Control panel 13 is electrically connected with projector 8, projection screen 9 respectively.
Described vertical supporting frame 4 is air spring structure, is provided with telescopic vertical piston rod 41, and holder 6 is arranged on the end of vertical piston rod 41, and holder 6 is provided with pulley 11, and bracing wire 10 is parallel with vertical supporting frame 4 through pulley 11.
Described motor 14 is provided with protective cover 15, and the bottom of control panel 13 is rotatably installed on protective cover 15.
Be provided with the snap ring 12 of fixing projection screen 9 immediately below described projection screen 9, described snap ring 12 is fixedly installed on cabinet 1.
The principle of work of air spring: air spring is using inert gas as elastic medium, seal lubrication is given and the flexible member of transmission of pressure with fluid, be called for short air spring, it is actually a kind of modification of telescopic air spring, there is the general characteristic of air spring constructions, air spring is generally made up of cylinder barrel, piston rod, seal and joint outer part, and the damping on piston makes rod chamber and rodless cavity communicate, and makes two cavity pressures equal.Utilize the compressibility of the gentle body of two chamber stress surface product moments to produce elastic force, air spring has light structure, and impulse stroke is large; Stable movement, can play damping buffering effect; Have stable close to constant characteristic line; Easy and simple to handle, safe and reliable.
Principle of work: during beginning, as shown in Figure 2, vertical supporting frame 4 and cross-brace frame 5 are all in compressive state, operation control panel 13 makes motor 14 be in idling conditions, vertical supporting frame 4 and cross-brace frame 5 start to extend under the pressure of self, until vertical supporting frame 4 stretches out complete, then cross-brace frame 5 crosses out to terminal, put down projection screen 9, projector 8 starts working.
After being finished, maneuvering and control plate 13, projection screen 9 is packed up, projector 8 closes, motor 14 works, and the belt wheel of its motor is wound around bracing wire 10, and cross-brace frame 5 first shrinks, after contraction, vertical supporting frame 4 starts to shrink, after treating that vertical supporting frame 4 shrinks, operation control panel 13, makes motor 14 quit work, and control panel 13 is put well, equipment set is removed.
Whole operating process can control automatically, easy to use, not easily damage equipment when advancing or use.
