The material of the lock mounting plate 1 is alloy steel, for example, 340LA.

[0044] In an embodiment, referring toFigure 1 The number of the flanges 12 is three, and the three flanges 12 are respectively connected with the upright column assemblies 3 corresponding to the upper side, the lower side and the inner side of the groove 32; two welding points are arranged on each flange 12.
