The utility model discloses a wire arrangement and wiring device for a computer room, and relates to the technical field of wire arrangement of the computer room. The wire arranging device comprises a bottom plate, the top of the bottom plate is fixedly connected with a plurality of first positioning blocks, the wire arranging device further comprises wire arranging mechanisms, the wire arranging mechanisms are arranged at the top of the bottom plate, the number of the wire arranging mechanisms is multiple, and each wire arranging mechanism comprises a bottom block positioned and installed on the bottom plate. According to the wire arranging mechanism, specifically, a group of multiple wire harnesses are sleeved on an arc-shaped block, then an arc-shaped buckle plate is overturned and inserted into the inner side of an arc-shaped elastic plate, and a triangular clamping block II on the arc-shaped elastic plate is matched with a triangular clamping block I to clamp and fix the arc-shaped buckle plate, so that a better arranging effect can be achieved, excessive accumulation of the wire harnesses is avoided, and the wire harnesses are prevented from being damaged. The arc-shaped elastic plate is pulled and pushed open through the second protruding plate, then the arc-shaped buckle plate is turned over and opened, the mode is easy and convenient to operate, follow-up maintenance is facilitated, and workers can find the wire harness more conveniently.
