A length-adjustable gutter cover having an anti-burglar device is provided to prevent the outward separation of each gutter cover against dynamic impact and to prevent the danger of burglaries. A length-adjustable gutter cover having an anti-burglar device comprises a first length-adjustment cover(1000) having a support wing(1200) projected to one side of the bottom of an inflow plate(1100) provided with a flowing-water hole(1110) and one or more anti-separation hinges(1300) projected to the other side, a second length-adjustment cover(2000) having a support wing(2200) projected to one side of the bottom of an inflow plate(2100) provided with a flowing-water hole(2110) and one or more anti-separation hinges(2300) projected to the other side correspondingly to the anti-separation hinges of the first length-adjustment cover, and an anti-burglar device fixing the first and second length-adjustment covers to a gutter and dividing into fixing bars(3100) formed on two side walls(W) and fixing spaces(2210) formed to the two length-adjusting covers, wherein the fixing bars are suspended on the bottom forming horizontal insertion spaces(2212) to each support wing to keep the two length-adjustment covers not to be separated outward, and the dynamic impact added on each length-adjustment cover is concentrated on the contact surface between the inflow plates of the length-adjustment covers and the contact surface between flowing-water projections(1500,2500) of each support wing and angles(3000,4000) to minimize the dynamic impact transferred to each anti-separation hinge. |
