Description
Technical field
The present invention relates to video display entertainment field, specifically a kind of folding type screen.
Background technology
" screen " this term is gained the name, because early stage film curtain with the addition of silver powder or aluminium in order to increase reflectivity
Powder.
The curtain showed a film, is initially made up of calico.Afterwards it is many using the cloth base for scribbling barium sulfate or metal dust or
The diffusing reflection screen that plastics are made.Also the reflection screen that useful bead reflective is made, and the transmission being made of trnaslucent materials
Screen.In silent film period, matte white pigment is scribbled on curtain, curtain face is smooth, is fixed with permanent screen carrier, holded up in putting
Reflect on platform.After sound film is born, because of transaudient needs, hole screen is formed with using rubber and plastic material.Make device behind the scenes
Loudspeaker send sound through screen.
In general, screen becomes easily infected by overhead when on the shelf in the surface of screen and the sound penetrating hole of screen
Dust in gas, and then image and sound when influenceing screen to show, so people are want when screen is on the shelf, by screen
Furled as curtain, played a protective role, but the traditional screen of problem often area, volume are larger so that people is difficult
Retracting operation is carried out with to screen.
The content of the invention
For above-mentioned technical problem, the present invention proposes a kind of folding type screen that can conveniently carry out wind-up operation.
A kind of folding type screen, mainly including framework, the frame front upper end is provided with curtain, and the curtain lower end is consolidated
Extension cloth is connected with, in the shape that collapses, the extension cloth lower end is supported with L panel seats, the L panel seats front end for the lower half of the extension cloth
Postive stop baffle is provided with front and rear sliding type, spring, the limiting block are connected between the postive stop baffle and the L panel seats
Plate offsets conjunctions with cloth is extended, and the postive stop baffle front end is welded with the company being fixedly linked with the end at the end that collapses for extending cloth
Fishplate bar.
The L panel seats rear end is welded with linkage board, and the linkage board slidably connects polished rod, the linkage board threaded connection
There is ball-screw, the ball-screw is connected with motor.
The ball-screw, polished rod are so that axially bearing of trend is arranged on the rear portion of framework vertically.
When in use, can act on drive linkage board and L panel seats by screw nut driven carries out longitudinal cunning to the said equipment
Move, and then enable that L panel seats and postive stop baffle drive extension cloth and curtain to be risen or declined.Wherein, rising
When, extend cloth and curtain and be in the state being gradually retracted, and extend the position that collapses of cloth bottom can be with the height for rising
Degree increases and volume increases, and collapses position while increase, and postive stop baffle can be squeezed, and then slide forwards, reach
The effect furled to curtain.
The beneficial effects of the invention are as follows：
It is characteristic of the invention that it is easy to use, and projection screen curtain can be wound in automation mode high, and make
It is simple to operate with facilitating, screen can be played a good protection.
Brief description of the drawings
Invention is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is main structure diagram of the invention；
Fig. 2 is the A-A cross section structure diagrams on Fig. 1 of the invention.
Specific embodiment
In order that the technological means realized of the present invention, creation characteristic, reached purpose and effect are easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1 to Figure 2, a kind of folding type screen, mainly includes framework 1, and the nock of the framework 1 is provided with curtain
Cloth 2, the lower end of the curtain 2 is fixed with extension cloth 3, and the lower half for extending cloth 3 is in collapse shape, the lower end branch of the extension cloth 3
L panel seats 4 are held, the front end of L panel seats 4 is provided with postive stop baffle 5, the postive stop baffle 5 and the L plates with front and rear sliding type
Be connected with spring 6 between seat 4, the postive stop baffle 5 with extend cloth 3 and offset conjunction, the front end of the postive stop baffle 5 be welded with it is described
Extend the connecting plate 10 that the end at the end that collapses of cloth 3 is fixedly linked.
The rear end of L panel seats 4 is welded with linkage board 7, and the linkage board 7 slidably connects polished rod 11, the spiral shell of the linkage board 7
Line is connected with ball-screw 8, and the ball-screw 8 is connected with motor 9.
The ball-screw 8, polished rod 8 are so that axially bearing of trend is arranged on the rear portion of framework 1 vertically.
When in use, can act on drive linkage board 7 and L panel seats 4 by screw nut driven carries out longitudinal direction to the said equipment
Sliding, and then enable that L panel seats 4 and postive stop baffle 5 drive extension cloth 3 and curtain 2 to be risen or declined.Wherein,
When rising, extend cloth 3 and curtain 2 and be in the state being gradually retracted, and extend the position that collapses of the bottom of cloth 3 can be with
The height of rising increases and volume increases, and collapses position while increase, and postive stop baffle 5 can be squeezed, then forwards
Sliding, reaches the effect furled to curtain 2.
General principle of the invention, principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, the simply present invention described in above-described embodiment and specification
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improvement is both fallen within claimed invention.The claimed scope of the invention is by appending claims and its equivalent circle.
It is fixed.
