Description
Technical field
The present invention relates to video display entertainment technologies field, a kind of gathering formula movie screen automatically.
Background technology
Along with the raising increasingly of China's living standard per capita, the pursuit that amusement is enjoyed by people improves day by day,
Cinema is favored as the cheap and economical the most current most of people in abstract the recreational consumption place.Now in order to
Improve the protectiveness of screen of showing a film, prevent the sound penetrating hole in screen to be infected with by the dust in air, one
As after motion picture projection, all can use automatic winding mode that screen is carried out rolling, play certain protection
Effect, but the shortcoming of this rolling is to need by one end elder generation rolling of screen on certain root axle, then by one
The mechanically or electrically control device of series is connected with the elongated end of this axle and could control the rotation of this axle, reaches automatic
Rolling and the effect pulled open, but the defect of this embodiment is to open the speed with rolling too slowly, also can make
Obtain mechanically or electrically control device exposed outside, affect people and view and admire the visual experience of film.
Summary of the invention
For the deficiency of above-mentioned technology, the present invention is on the basis of having automatic deploying and retracting function, it is proposed that a kind of
A kind of gathering formula movie screen automatically that can draw in centre position.
A kind of automatically draw formula movie screen in, including rearmounted seat and screen, on rear side of described screen left part, right-hand member
Rear side has been respectively fixedly connected with left fixed plate, right fixed plate, and described left fixed plate, right fixed plate are all slided with level
Mode is arranged on the front lower end of rearmounted seat.
The upper end at described left fixed plate rear portion, lower end have been respectively articulated with left connecting rod, described right fixed plate rear portion
Upper end, lower end have been respectively articulated with right connecting rod, have realization and incite somebody to action the two between described left connecting rod and described right connecting rod
The center-pole being hinged and connected, described center-pole rear end is all connected with rope sheave, is arranged on rearmounted seat along longitudinally fixed
Extension spring.
There is between two rope sheaves the rope band the two transmission being connected, described rope band is fixed with fastening lock, institute
Stating and have the translot being slidably installed in the horizontal direction by fastening lock on rearmounted seat, described rearmounted base rear end rotates peace
Equipped with the ball-screw being connected with fastening lock screw thread, described ball-screw is connected by shaft coupling motor.
Described fastening is locked, the lengthwise position of both translots central area between two rope sheaves.
Have, on the front end face of described rearmounted seat, the end slipway installed by two center-poles along longitudinal sliding motion.
When screen is drawn in by needs, it is only necessary to start motor, ordered about tightly by the gearing of ball-screw
Admittedly level to the left of locking is slided, and then is pulled to the left by rope band by fastening lock so that two center-poles are along with two
Individual rope sheave together slides towards the position at translot place, causes left connecting rod, right connecting rod to rotate, and left
Fixed plate, right fixed plate are homogeneous carries out sliding with towards direction, middle part, reaches to carry out screen carrying out to centre
The effect drawn in.
When screen is launched projection by needs, by motor reversal, drive fastening to lock level to the right and slide, reach
Effect that rope sheave is loosened, and two center-poles are all under the effect of extension spring, enter to upper and lower respectively
Line slip, causes left connecting rod, right connecting rod to rotate round about, and left fixed plate, right fixed plate
The most to the left, right side carry out sliding, reach effect that screen both sides to the left and right are carried out launches.
It is a feature of the present invention that and the present invention relates to major part mechanical controling part and electric controling part
It is respectively positioned on rearmounted seat rear or the rear of screen, when either drawing in screen or launch projection in screen,
All will not expose on front visual angle, and then relatively improve the visual perception of people, the present invention uses in addition
Two-way screen gathering or bidirectional open mode unidirectional are opened or compared with unidirectional tucked way with traditional, and speed is more
Hurry up, and then indirectly can carry soon the time point of film projection.
The invention has the beneficial effects as follows:
Automaticity of the present invention is high, by screw nut driven and the rope sheave kind of drive, reaches to control screen
Automatically the function drawn in and launch, plays the protective effect to screen；In addition the present invention not only screen is received
Hold together the good visual effect opened with screen, and speed, carry soon the time point of film projection.
