[0005] A wall-hanging keel for both clamping and hanging is formed by bending a plate, comprising a main body, one side of the main body having an opening, a cavity formed inside the main body, a clamping structure formed in the opening area of ​​the main body, and a hanging hole formed on one side of the opening of the main body or / and a side facing away from the opening.

[0006] The present application can realize two installation modes: hanging and clamping, and has strong adaptability.

[0008] The clamping structure comprises two clamping parts symmetrically arranged about the opening, and the clamping parts have a first folding plate, a second folding plate, a third folding plate and a fourth folding plate connected in sequence;

[0009] The first folding plate is connected to an end of the third side wall away from the second side wall, the first folding plate is perpendicular to the third side wall, and the first folding plate and the first side wall are respectively located on both sides of the third side wall;

[0011] The third folding plate is in contact with the inner side wall of the third side wall;

[0012] The fourth folding plate is arranged at an acute angle with the third folding plate.

[0013] In order to meet the elastic tolerance, the clamping force of the current clamping installation structure is generally insufficient, causing the panel to bulge outward.
