The utility model discloses a novel wall lamp fixing structure of clamping groove formula, including lamp body, hanging plate and quick -mounting mechanism, wherein the lamp body includes wall box, and quick -mounting mechanism includes clamping position short pole and clamping position groove, and clamping position groove adopts again the structure setting of clamping access and limiting access, and clamping position short pole will be clamped into limiting access when cooperating clamping clamping position groove, at this moment, hanging plate will be completely embedded in the embedded groove, and the quick fixing of wall box is completed, the fixing structure restricts the freedom of lamp body to separate and to be far away from hanging plate through the cooperation of clamping position short pole and clamping position groove, and the horizontal freedom of lamp body is limited through the
abutment cooperation of hanging plate and embedded groove, prevents lamp body to sway, realizes the effect of the quick installation of lamp body on the wall, and also makes the installation of lamp body more firm and reliable.
