Title:
FASTENING CONNECTOR COMPONENT AND STRUCTURE, REMOVING METHOD, TRACK STRUCTURE, CRANKSHAFT CONNECTING MECHANISM, FRAME CONNECTING APPARATUS, AND FRAME CONNECTING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/020865
Kind Code:
A1
Abstract:
A fastening connector structure comprising a parent (1), an attachment (2), a fastening connector component. The fastening connector component comprises a threaded bolt (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). An extraction structure for extracting the rotation-stopping sleeve (7) from a first rotation-stopping hole (10) is provided on the periphery of the rotation-stopping sleeve (7) mounted within the first rotation-stopping hole (10) protruding the fastening nut (6). 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. 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 first 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 nut (6) does not rotate in reverse and come loose relative to the threaded rod (5). The rotation-stopping sleeve (7) can be extracted conveniently, quickly, and reliably from the first rotation-stopping hole (10).
