Abstract:
A fastening connector structure comprising a parent (1), an attachment (2), and a fastening connector component. The fastening connector component comprises a threaded rod (5), a fastening nut (6), and a rotation-stopping sleeve (7). The threaded rod (5) runs through the parent (1) and the attachment (2) to be threadedly connected with the fastening nut (6). Provided on the fastening nut (6) are a first rotation-stopping hole (10) and two or more extraction grooves (20) running through the wall of the first rotation-stopping hole (10), the periphery of the fastening nut (6), and the top surface of the wall of the first rotation-stopping hole (10). The rotation-stopping sleeve (7) is mounted on the exterior of the threaded rod (5) and within the first rotation-stopping hole (10) and is axially limited within the first rotation-stopping hole (10). A first rotation-stopping part (11) on the wall of the first rotation-stopping hole (10) of the fastening nut (6) fits a second rotation-stopping part (13) at the periphery of the rotation-stopping sleeve (7) to restrain rotation of the fastening nut (6) relative to the rotation-stopping sleeve (7). A third rotation-stopping part (14) on the wall of a rotation-stopping through hole (12) of the rotation-stopping sleeve (7) fits a fourth rotation-stopping part (19) of the threaded rod (5) to restrain rotation of the rotation-stopping sleeve (7) relative to the threaded rod (5). The threaded rod (5) is non-rotatably mounted together with the fastening nut (6). The fastening connector structure prevents the fastening nut (6) from rotating in reverse and coming loose relative to the threaded rod (5) and allows the rotation-stopping sleeve (7) to be extracted conveniently, quickly, and reliably from the first rotation-stopping hole (10).
