Claim:
A computer housing comprising: a computer chassis comprising a rear panel; a bracket being attached to the rear panel of the computer chassis, the bracket comprising a crossbeam, the crossbeam comprises spaced first and second side plates perpendicular to the rear panel; a first cover and a second cover each pivotally attached to the bracket and rotated reversely, the first cover rotating relative to a pivot end thereof adjacent to the first side plate of the crossbeam, the second cover rotating relative to a pivot end thereof adjacent to the second side plate of the crossbeam, a blocking plate extending perpendicularly from the pivot end of the first cover, a lug extending perpendicularly from the pivot end of the second cover, the lug defining a through aperture, the crossbeam being located between the first and second covers; and a locking device comprising a latch and a spring, the latch including a first pin portion, a second pin portion, and a flange located between the first pin portion and the second pin portion; the latch being slidably mounted to the crossbeam while the first pin portion is able to pass through the first side plate of the crossbeam and the second pin portion is able to pass through the second side plate of the crossbeam, the flange being received between the first and second side plates, and two ends of the spring abutting against the second side plate and the flange respectively; wherein when the first cover is closed, the blocking plate of the first cover presses the first pin portion of the latch so that the second pin portion of the latch is inserted into the through aperture of the lug of the second cover and wherein when the first cover is open, the blocking plate of the first cover leaves the first pin portion of the latch so that the second pin portion of the latch is withdrawn from the through aperture of the lug of the second cover.
