Connection piece structure for connecting joint screens

Abstract

The invention relates to the field of projection large-screen joint walls, in particular to a connection piece structure for connecting joint screens. The connection piece structure comprises a connection piece, wherein locating parts for locating the surfaces of adjacent screens are arranged in the contacted parts of the inner side of the bent part of the connection piece and the screens. As the locating parts are arranged in the contacted parts of the inner side of the bent part of the connection piece and the screens, when the connection piece is inserted in through holes of the adjacent screens for fixing, the locating parts and ejection plates between the adjacent screens are interacted to automatically form a locating effect on the surfaces of the screens, so that the surfaces of the adjacent screens can be smoothly aligned to each other to eliminate the surface range between the adjacent screens, the smooth transition of the joint surfaces of the adjacent screens is realized, and the frame completeness of the screens is guaranteed.

Description

technical field [0001] The present invention relates to the field of splicing walls for large projection screens, and more particularly, relates to a connector structure for connecting splicing screens. Background technique [0002] A large-screen projection video wall is generally composed of m * n projection units, and the imaging screen of each unit is generally made of a light diffusion layer and a Fresnel lens. Such as figure 2 As shown, the connection between adjacent spliced ​​screens 1 is generally realized through the through holes of the two adjacent screens 1 through the connecting piece 2, and the connecting piece 2 is generally a U-shaped metal nail. However, due to the limitations of the shape of the pins between the screens 1, the middle part of the pins connecting the two screens 1 generally presents an arc shape 11 after being bent twice, and a considerable bending arc must be ensured to meet the bending requirements. It is not easy to break, which makes t...

Problems solved by technology

However, due to the limitations of the shape of the pins between the screens 1, the middle part of the pins connecting the two screens 1 generally presents an arc shape 11 after being bent twice, and a considerable bending arc must be ensured to meet the bending requirements. It is not easy to break, which makes the screen 1 spliced ​​and installed, and the surface between adjacent screens 1 is prone to unevenness, and the level difference b of 0.1-0.3mm is easy to occur between the surfaces of adjacent two screens. Enlarging the splicing gap will lead to light leakage and affect the integrity of the picture. Especially for the light diffusion layer screen composed of multi-layer microstructures, the position of the pinhole on the surface will be in frictional contact with the bending position 12 of the pin nail, resulting in the surface of the screen Delamination damage, affecting screen performance
