Document Type and Number:
WIPO Patent Application WO/2018/039947
Kind Code:
A1
Abstract:
Disclosed is a fastening connection structure, comprising a fastening connection assembly, a parent body (46) and an appendage body (47). The fastening connection assembly comprises a screw rod (31) and a screw-rod rotation stopping sleeve (40). A hole wall of a rotation-stopping through hole (41) of the screw-rod rotation stopping sleeve (40) is provided with an axial inner rotation-stopping portion (42), cooperating with an outer rotation-stopping portion (35) of a resisting portion (34) of the screw rod (31), of the screw-rod rotation stopping sleeve (40). A rotation-stopping projecting portion (43) of the screw-rod rotation stopping sleeve (40) is provided at an outer periphery of the screw-rod rotation stopping sleeve (40). A rotation-stopping projecting portion (48) of the appendage body (47) is provided on the appendage body (47). The parent body (46) and the appendage body (47) are fastened and connected to each other via the screw rod (31). The outer rotation-stopping portion (35) of the resisting portion (34) cooperates with the inner rotation-stopping portion (42) of the rotation stopping sleeve (40) of the screw rod (31) in a resisting manner so as to restrain the screw rod (31) from rotating relative to the screw-rod rotation stopping sleeve (40). The rotation-stopping projecting portion (48) of the appendage body (47) cooperates with the rotation-stopping projecting portion (43) of the screw-rod rotation stopping sleeve (40) in a circumferential resisting manner on a side of a screwing direction of the screw rod (31) so as to restrain the screw-rod rotation stopping sleeve (40) from rotating relative to the appendage body (47), such that the screw rod (31), the appendage body (47) and the parent body (46) are installed together in a non-rotating manner. The present invention has advantages of not requiring a rotation stopping piece and the machining of a rotation stopping hole on the appendage body (47). The rotation stopping sleeve (40) is quick, convenient, and reliable to install and remove. The screw rod (31) cannot rotate in reverse and become loose.
