Description
Technical field
The present invention relates to video display entertainment technologies field, specifically a kind of automatic gathering formula movie screen.
Background technology
With the raising increasingly of China's living standard per capita, the pursuit that people enjoy to amusement increasingly improves, film
Institute is that current most of people are favored as cheap and economical abstract the recreational consumption place.Now in order to improve silver of showing a film
The protectiveness of curtain, prevents the sound penetrating hole in screen to be infected with by the dust in air, typically after motion picture projection, can all use
Automatic winding mode is wound screen, plays certain protective effect, but needed the shortcomings that this winding by screen
One end is first wound on certain root axle, is then connected by a series of mechanically or electrically control device with the elongated end of this axle ability
Control this axle to rotate, the effect of reaching automatic winding and pull open, but be opening and the speed of winding the defects of this embodiment
It is too slow, it can also make it that mechanically or electrically control device is exposed outside, influence the visual experience that people view and admire film.
The content of the invention
For the deficiency of above-mentioned technology, the present invention is on the basis of with automatic deploying and retracting function, it is proposed that one kind can be in
Between one kind for collapsing of position is automatic collapses formula movie screen.
A kind of automatic gathering formula movie screen, including rearmounted seat and screen, the screen left part rear side, right-hand member rear side are respectively
Left fixed plate, right fixed plate are fixed with, before the left fixed plate, right fixed plate are slidably mounted at rearmounted seat with level
Lower end.
Upper end, the lower end of the left fixed postlaminar part have been respectively articulated with left connecting rod, the upper end of the right fixed postlaminar part, under
End has been respectively articulated with right connecting rod, has the center-pole realized and be hinged and connected the two between the left connecting rod and the right connecting rod,
The center rod rear end is connected with rope sheave, along the longitudinally fixed extension spring on the rearmounted seat.
There is the rope band that the two transmission is connected between two rope sheaves, fastening lock is fixed with the rope band, it is described rearmounted
The translot locked and be slidably installed in the horizontal direction will be fastened by being provided with seat, and the rearmounted base rear end is rotatably installed with and fastening lock screw thread
Connected ball-screw, the ball-screw are connected with motor by shaft coupling.
The fastening lock, central area of the lengthwise position of both translots between two rope sheaves.
The end slipway for installing two center-poles along longitudinal sliding motion is provided with the front end face of the rearmounted seat.
When needing to collapse screen, it is only necessary to start motor, by the gearing of ball-screw drive fastening lock to
Left horizontal slip, and then pulled rope band to the left by fastening lock so that two center-poles are as two rope sheaves are together towards horizontal stroke
Line slip is entered in position where groove, causes left connecting rod, right connecting rod rotation, and left fixed plate, right fixed plate are homogeneous with
Line slip enters in direction in portion, reach by screen carry out to centre collapsed the effect of.
When needing to deploy to show by screen, by motor reversal, drive fastening lock is horizontal to the right to slide, reach and rope sheave is entered
Row the effect of loosening, and two center-poles are slided to upper and lower respectively in the presence of extension spring, cause left connecting rod,
Right connecting rod is rotated round about, and left fixed plate, right fixed plate respectively to the left, right side enter line slip, reach by
Screen the effect of both sides are deployed to the left and right.
It is respectively positioned on it is a feature of the present invention that the present invention relates to most of mechanical controling part and electric controling part
Rearmounted seat rear or the rear of screen, will not be at preceding visual angle either when screen is collapsed or deploys to show in screen
On exposed, and then the relative visual perception for improving people, in addition the present invention use two-way screen gathering or bidirectional open side
For formula compared with traditional unidirectional opening or unidirectional tucked way, speed faster, and then can carry soon the time of film projection indirectly
Point.
The beneficial effects of the invention are as follows：
Automaticity of the present invention is high, by screw nut driven and the rope sheave kind of drive, reaches control screen and carries out certainly
The dynamic function of collapsing and deploy, plays the protective effect to screen；In addition not only screen gathering regards the present invention with what screen was opened
Feel that effect is good, and speed, carry soon the time point of film projection.
