Back frame structure for display panel and display device

The invention provides a back frame structure for a display panel and a display device. The back frame structure comprises a back plate, a middle frame and an outer frame, and the back plate is provided with a bottom face and a side wall surrounding the bottom face so as to define a containing space; the middle frame is provided with a clamping unit, the clamping unit is located on the side, away from the containing space, of the side wall, and the clamping unit is configured to deform under the action of external force; the outer frame is located on the side, away from the side wall, of the middle frame, and the outer frame is connected with the clamping unit in a clamped mode. Therefore, according to the back frame structure, through deformation of the clamping units, the outer frame and the middle frame can be conveniently and rapidly disassembled and assembled, the manufacturing cost is reduced, the assembling efficiency is improved, and the back frame structure is good in stability and has a good using e
