The application discloses an acetylene bottle protective cover which comprises a top sunscreen cover in the shape of an umbrella for covering the top of an acetylene bottle to prevent the acetylene bottle from being exposed to sunlight, and a first bottle body protective cover arranged below the top sunscreen cover for accommodating and fixing the bottle body of the acetylene bottle to keep the acetylene bottle vertically placed, wherein a gap is arranged between the top sunscreen cover and the first bottle body protective cover for exposing the valve of the acetylene bottle. The acetylene bottle protective cover covers the top of the acetylene bottle through the top sunscreen cover to prevent the direct sunlight from causing the risk of burning or explosion. In addition, the first bottle body protective cover is arranged to fix the bottle body and keep the acetylene bottle vertically placed, thereby preventing acetone from flowing out and tempering, reducing the risk of valve damage and improving the safety in use.

This utility model relates to the field of door leaf profile technology and discloses a novel corner assembly insert for door leaves, including two corner assembly pieces arranged symmetrically. A first corner segment is fitted onto the outer side of the upper corner assembly, and a second corner segment is fitted onto the outer side of the lower corner assembly. This utility model's technical solution can, through the cooperation of a limiting plate on a positioning frame, limit the position of the two corner assembly pieces, avoiding the inconvenience of pre-fixing the corner assembly pieces with bolts. Furthermore, the first arc-shaped block can drive the clamping strip to abut against the inner walls of the first and second corner segments respectively, thereby achieving connection limitation between the corner assembly piece and the first and second corner segments. It also ensures the aesthetics of the connection between the first and second corner segments and eliminates the need for workers to cut the two corner segments into corresponding bevels, thus improving the assembly efficiency of the first and second corner segments.
