Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1

As shown in fig. 1, an inside corner closing line 1 is an integrally formed part and has an L-shaped strip structure, and the inside corner closing line 1 has a ceiling connecting surface 101, a wall surface connecting surface 102, and a board inserting surface 103. Due to the adoption of the integral forming technology, the whole internal corner closing line is stable in structure and high in strength, and the strength of the internal corner closing line is at least improved by more than 80% compared with that of a wood spliced internal corner closing line. The upper surface of the ceiling attachment surface 101 is a smooth planar structure, which is closely attached to the ceiling, and has a fixing and mounting hole 104 for fixing the reentrant corner entry line 1 to the ceiling. Because the whole internal corner closing line 1 only has one fixed mounting hole 104, the installation of the internal corner closing line can be finished only by screwing a screw into the fixed mounting hole 104, so that the whole internal corner closing line 1 is very convenient to install and can be quickly installed. When the fixing and installing hole 104 is located at 1/3 on the right end of the ceiling connecting surface 101, the installation of the internal corner closing line 1 is most convenient, the installation stability is best, and the fixing effect of the plate is best. The wall surface connecting surface 102 is vertically connected with the ceiling connecting surface 101 and clings to the wall surface. The board insertion surface 103 is perpendicular to the wall surface connection surface 102. The board splicing surface 103 has the same length and width, is of a square structure, has a decoration function, and is used for covering a gap between a ceiling and a wall surface.
