Anti-loosing structure and backlight module

A backlight module, comprising:

• a first frame;
• a second frame;
• and
• an anti-loosing structure, comprising:
• a first buckle element mounted to the first frame, and comprising a first substrate and a clamping portion disposed on the first substrate;
• and
• a second buckle element mounted to the second frame, and comprising a second substrate, an embedding portion disposed on the second substrate, and an anti-loosing block;
• wherein the embedding portion is made of an elastic material, the anti-loosing block is movably disposed in the embedding portion, and is configured to cause the embedding portion to be elastically expanded, wherein the embedding portion is configured to be inserted into the clamping portion, causing the embedding portion to connect to the clamping portion by interference fitting.
