Description

Technical Field

[0001] The utility model relates to the technical field of light boxes, in particular to a light box with a self-dropping light box cover. Background Art

[0002] The light box is a viewing light box (illuminator) for viewing X-ray photos (negative films). The light box is generally made of light sheets, preferably PC boards, which can withstand high temperatures of up to 145 degrees and low temperatures of up to -55 degrees. When replacing the internal LED light, the operation is complicated and the replacement is inconvenient.

[0003] The Chinese utility model patent with application number 202120853024.7 discloses a light box with a self-falling light box cover. The above technical scheme is provided with two second grooves at the front and rear ends of one side of the bottom of the inner groove, and the limit blocks are fixed at the bottom ends of the two second grooves.
