Abstract
The invention relates to a folded screen, which mainly comprises a frame, wherein a curtain is arranged at the upper end of the front part of the frame; the lower end of the curtain is fixedly connected with extension cloth; the lower half part of the extension cloth is in a folded form; an L plate seat is supported at the lower end of the extension cloth; a limiting baffle plate is arranged at the front end of the L plate seat in a manner of sliding back and forth; a spring is connected between the limiting baffle plate and the L plate seat; the limiting baffle plate abuts on the extension cloth; a connection plate which is fixedly connected with the tail end of the folded end of the extension cloth is welded at the front end of the limiting baffle plate; a linkage plate is welded at the rear end of the L plate seat and is connected with a polish rod in the sliding manner; the linkage plate and a ball screw are in threaded connection; and the ball screw is connected with a motor. The folded screen has the characteristics of being convenient to use and simple to operate, can roll up the curtain in a high automatic manner, and can play a good protecting role on the screen.
Description
Technical field
The present invention relates to video display entertainment field, specifically a kind of folding type screen.
Background technology
Gaining the name of " screen " this term is because early stage film curtain with the addition of silver powder or aluminium powder to increase reflectivity.
The curtain of showing a film, is made up of calico at first.Use the diffuse reflection screen that the cloth base scribbling barium sulphate or metal powder or plastics are made afterwards more.Also the useful bead reflective reflection screen of making, and with the transmission screen that trnaslucent materials is made.Silent film period, curtain scribbles matte white pigment, curtain face is smooth, fixes with permanent screen carrier, holds up on projection platform.After talkie is born, because of transaudient needs, rubber and plastic material is adopted to make porose screen.Device loudspeaker is behind the scenes sounded through screen.
In general; screen is time on the shelf; the dust in air is all becomed easily infected by the surface of screen and the sound penetrating hole of screen; and then affect screen projection time image and sound; so people want, when screen is on the shelf, screen is furled as curtain, play a protective role; but the traditional screen of problem often area, volume is comparatively large, makes people be difficult to carry out retracting operation to screen.
Summary of the invention
For above-mentioned technical matters, the present invention proposes a kind of folding type screen conveniently can carrying out wind-up operation.
A kind of folding type screen, mainly comprise framework, described frame front upper end is provided with curtain, described curtain lower end is fixed with extension cloth, the Lower Half of described extension cloth is in the shape that collapses, described extension cloth lower end is supported with L panel seat, described L panel seat front end is provided with postive stop baffle with front and back sliding type, spring is connected with between described postive stop baffle and described L panel seat, described postive stop baffle all offsets with extension cloth and closes, and described postive stop baffle front end is welded with the web joint be fixedly linked with the end held of collapsing of described extension cloth.
Described L panel seat rear end is welded with linkage board, and described linkage board slidably connects polished rod, and described linkage board has been threaded ball-screw, and described ball-screw is connected with motor.
Described ball-screw, polished rod all axially vertical bearing of trend are arranged on the rear portion of framework.
The said equipment in use, drives linkage board and L panel seat to carry out straight skidding by screw nut driven effect, and then makes L panel seat and postive stop baffle that extension cloth and curtain can be driven to carry out rising or declining.Wherein, when rising, extension cloth and curtain are in the state be retracted gradually, and the position that collapses of extension cloth bottom can be increased along with the height risen and volume increase, collapse position while increase, postive stop baffle can be squeezed, then forwards slippage, reaches the effect furled curtain.
The invention has the beneficial effects as follows:
Feature of the present invention is easy to use, and can carry out rolling in high automation mode to projection screen curtain, and easy to use simple to operate, can play a good protection to screen.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, invention is further illustrated.
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is the A-A sectional structure schematic diagram of the present invention about Fig. 1.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the present invention being set forth further.
As shown in Figure 1 to Figure 2, a kind of folding type screen, mainly comprise framework 1, described framework 1 nock is provided with curtain 2, described curtain 2 lower end is fixed with extension cloth 3, the Lower Half of described extension cloth 3 is in the shape that collapses, described extension cloth 3 lower end is supported with L panel seat 4, described L panel seat 4 front end is provided with postive stop baffle 5 with front and back sliding type, spring 6 is connected with between described postive stop baffle 5 and described L panel seat 4, described postive stop baffle 5 all offsets with extension cloth 3 and closes, described postive stop baffle 5 front end is welded with the web joint 10 be fixedly linked with the end held of collapsing of described extension cloth 3.
Described L panel seat 4 rear end is welded with linkage board 7, and described linkage board 7 slidably connects polished rod 11, and described linkage board 7 has been threaded ball-screw 8, and described ball-screw 8 is connected with motor 9.
Described ball-screw 8, polished rod 8 all axially vertical bearing of trend are arranged on the rear portion of framework 1.
The said equipment in use, drives linkage board 7 and L panel seat 4 to carry out straight skidding by screw nut driven effect, and then makes L panel seat 4 and postive stop baffle 5 that extension cloth 3 and curtain 2 can be driven to carry out rising or declining.Wherein, when rising, extension cloth 3 and curtain 2 are in the state be retracted gradually, and the position that collapses of extension cloth 3 bottom can be increased along with the height risen and volume increase, collapse position while increase, postive stop baffle 5 can be squeezed, then forwards slippage, reaches the effect furled curtain 2.
More than show and describe ultimate principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and instructions; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in claimed the present invention.Application claims protection domain is defined by appending claims and equivalent thereof.
