Liquid crystal display with plug-in type mainboard assembly structure

The invention discloses a liquid crystal display with a plug-in type mainboard assembly structure, which comprises an outer shell bin, a cylindrical bin is mounted in the middle of one side of the outer shell bin, two groups of inner shell bins are symmetrically hinged to two ends of one side, far away from the cylindrical bin, in the outer shell bin, and liquid crystal display screens are mounted in the four groups of inner shell bins. A display screen unfolding assembly matched with the inner shell bin is arranged in the middle of the interior of the outer shell bin. Two sets of second lead screws are controlled to rotate synchronously, two sets of second internal thread blocks on the second lead screws are forced to be far away from each other, inner shell bins are pushed through connecting plates to turn outwards with hinge shafts of the inner shell bins and the outer shell bins as axes in the process, and at the moment, the four sets of inner shell bins are automatically opened towards the outer sides of
