The invention provides a picture frame convenient to disassemble, assemble and transport. The picture frame convenient to disassemble, assemble and transport comprises a rectangular bottom plate, a border assembly and a frame pressing assembly which is located between the bottom plate and the border assembly, and a first magnet set is arranged on the periphery of the surface of the bottom plate; the frame pressing assembly comprises four independent pressing plates, each pressing plate is provided with a second magnet set, and the four pressing plates are in magnetic connection with the bottom plate by attraction force between the second magnet sets and the first magnet set; the border assembly comprises four independent borders, and the four pressing plates are pressed by the four borders respectively. According to the picture frame convenient to disassemble, assemble and transport, calligraphy and painting mounting can be achieved rapidly, and by means of the magnetic attraction force of the first magnet set and the second magnet sets, position locating of each pressing plate on the bottom plate can be completed automatically; during disassembly, the pressing plates are manually removed only, no tool is needed, and disassembly is facilitated greatly. The border assembly comprises the four independent borders, and therefore during transportation, the four borders and the four pressing plates are convenient to transport.
