Abstract: A pivoting assembly with a positioning function includes a base and a casing assembled with the base. The base is provided with curved elastic arms and two fixing supports. Each fixing support has a pivotal hole. One surface of the casing is formed with a curved portion for allowing the curved elastic arm to abut against and two holes for allowing the fixing support to pass through. The other surface of the casing is formed with a protrusion pivotally connected to the pivotal hole. When the curved portion slides on the curved elastic arm, elastic abutment between the curved portion and the curved elastic arm makes the casing to be positioned by friction fit with respect to the base.

Each fixing support has a pivotal hole. One surface of the casing is formed with a curved portion for allowing the curved elastic arm to abut against and two holes for allowing the fixing support to pass through. The other surface of the casing is formed with a protrusion pivotally connected to the pivotal hole. When the curved portion slides on the curved elastic arm, elastic abutment between the curved portion and the curved elastic arm makes the casing to be positioned by friction fit with respect to the base. By this structure, the present invention can be positioned without a positioning pin or bolt. Further, the present invention is simple in structure, easy to assemble and low in production cost.

Abstract: The invention provides an assembly structure of a back light module having two horizontal frames, two vertical frames and an optical plate. At both ends of each horizontal frame and vertical frame is equipped noncircular holes and pillars, and a plurality of chutes is equipped on the corresponding surfaces of the two horizontal frames to intervene each other for assembling the two horizontal frames and the two vertical frames to a complete frame. The two sides of the optical plate are formed the fixed supports that have a slant corresponding to the chute for installing the optical plate into the complete frame, and the fixed support is embedded into the chute of the horizontal frame. In accordance with the design of embedded structure, the invention can achieve effects of easy assembly, firm structure, low cost and easy disassembling.
