Abstract

The utility model relates to a splicing structure for large screen projecting displaying walls, which comprises a spliced single screen and connected metal strip frames, wherein convex wedges are arranged on every side wall of the single screen, the side walls of the thin and narrow metal strip frames are provided with corresponding rectangular connecting holes, the wedges are respectively inserted into the corresponding rectangular connecting holes from the left and the right, and the metal strip frames are respectively and orderly connected into a complete structure horizontally and vertically. A seam occupies small width and does not damage image areas, and the circumference of the single screen is surrounded by the metal strip frames; thus, the utility model prevents deformation caused by various reasons, has supporting strength and can bear by self.

Description

Large screen projection display wall splicing construction

The utility model belongs to the electronic display unit technical field, specially refers to the splicing that utilizes the large screen projection display wall.

Along with rapid development of science and technology, utilize electronic display technology to carry out information interchange, more and more become indispensable means.No matter in military affairs, command centres such as public security, railway, the aviation dispatching center, still in finance, the securities information display centre, all needing to carry out in time information shows, owing to contain much information, the personnel that watch simultaneously are many, therefore be sought after the bigger screen display of broad, so as not to constantly skipping, the display packing majority that adopts in the world is that large screen projection shows at present, for requiring the more situation of large scale demonstration, for example width surpasses 200 inches situation, and is perhaps more for information source, the situation that whole screen display resolution is had relatively high expectations, just the splicing that must adopt large screen projection to show is about to a plurality of projectors and projection screen and forms display, by suitable structure screen is coupled together and forms the very big Projection Display " wall " of one side, the fundamental purpose of splicing construction, only little optical displays is connected into large tracts of land, whether the width that to estimate its good and bad leading indicator be seam destroys the quality that image shows, whether projection screen in use is out of shape and bearing strength.

At present the splicing construction that adopts in the world has several: 1, adopt on the screen and punch, connect with the metal wire perforation, but that seam occupies width is big, technology is complicated, and yield rate is not high; 2, adopt and to punch on the metal tank bracket, the punching of screen sidewall connects together screen and framework with pin feature again, but has big stress on this method screen, connect on the level comparatively difficult, also easy deformation; 3, bonding method, the firm intensity difference of this method is not suitable for than large-screen splicing.

In sum, domestic each optical projection system group company wishes that all a kind of comparatively science is arranged, practical joining method comes out, and rely on external import splicing construction and expensive price simply to change, thereby we needs in conjunction with this, have developed a kind of new structure.

The purpose of this utility model, defectives such as chain link is wide in the existing large-screen splicing structure, yield rate is low in order to overcome, yielding and firm intensity difference, and design a kind of new splicing construction, promptly joint gap is thin, yield rate is high, not yielding, the joining method that bearing strength is big.

The utility model relies on following technical proposals to realize, a kind of splicing construction of large screen projection display wall, comprise the single screen that is spliced and the metal frame of connection, it is characterized in that, each sidewall of single screen is provided with the projection of chock shape, sidewall at carefully narrow metal frame has corresponding rectangle connecting hole, inserts from right and left respectively for chock, is in turn connected into complete structure in level with vertical direction respectively.

The advantage of this programme is that it is little that this seam occupies width, do not destroy image area, is surrounded by metal frame around the single screen, promptly prevents the distortion that screen causes because of a variety of causes, has support strength again, reaches the self-supporting effect.

Further specify embodiment below in conjunction with accompanying drawing:

Description of drawings:

Fig. 1 is single screen construction synoptic diagram;

Fig. 2 is for connecting the structural representation of metal frame;

Fig. 3 is the structural drawing of the large screen projection display wall of having spliced.

Wherein, single display screen 1, its sidewall is connected with the projection 2 of chock shape, the side width of metal frame 3 is identical with the thickness b of single screen, the thickness a in metal frame 3 fronts is the width of splicing seams, is very narrow as can be known, is distributed in the rectangle aperture 4 of metal frame side, the chock that protrudes with single screen side just in time coincide, and constitutes complete giant-screen.

This splicing construction is not limit the quantity that is spliced single screen, according to the area size of required giant-screen, and the corresponding single screen number that is spliced of choosing.

The most preferred embodiment example is made six, nine single screens respectively and is pieced together the giant-screen structure of tying, and shields thick 6mm, and metal frame is that stainless steel is made, and the wide a=3mm of bar, sidewall open the jack cross section and be (2 * 5) mm ²The large-screen picture clear display, splicing intensity is firm.

Claims

1, a kind of splicing construction of large screen projection display wall, comprise the single screen that is spliced and the metal frame of connection, it is characterized in that, each sidewall of single screen is provided with the projection of chock shape, sidewall at carefully narrow metal frame has corresponding rectangle connecting hole, insert from right and left respectively for chock, be in turn connected into complete structure in level with vertical direction respectively.

2, structure according to claim 1 is characterized in that, this splicing construction is not limit the quantity that is spliced single screen, according to the area size of required giant-screen, and the corresponding single screen number that is spliced of choosing.
