Automobile wire harness fixing support

Abstract

This utility model relates to the field of wire harness fixing technology and discloses an automotive wire harness fixing bracket, including a fixing rod, an elastic bracket fixedly installed on one side of the fixing rod, a positioning cylinder sleeved on the other end of the fixing rod, a fixing strip fixedly installed on the other end of the positioning cylinder, and a wedge block fixedly installed on the inner side of the fixing strip. This utility model's technical solution allows the inclined surface on the positioning cylinder to push the positioning rod, causing the positioning rod to push the left side of the elastic bracket to move to the right, thereby deforming the left side of the elastic bracket and compressing and limiting the wire harness within the elastic bracket. After the positioning rod is inserted into the positioning groove, the position of the positioning rod and the positioning cylinder is defined. Alternatively, the semi-circular block can push the wedge block, causing the wedge block to deform the fixing strip, thus causing the three fixing strips to abut against the inner wall of the screw hole, thereby limiting the installation of the fixing rod. This achieves simultaneous fixing of the bracket and the wire harness in place.
