Title:
FASTENING CONNECTION STRUCTURE, ROTATION STOPPING STRUCTURE, FASTENING CONNECTION ASSEMBLY AND CRANKSHAFT CONNECTING ROD MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/039949
Kind Code:
A1
Abstract:
Disclosed is a fastening connection structure, comprising a fastening connection assembly, a parent body (14) and an appendage body (15). The fastening connection assembly comprises a screw rod (1) and a rotation stopping sleeve (2). A rotation stopping boss (11) of the rotation stopping sleeve, for restraining the rotation stopping sleeve (2) from rotating in the direction in which the screw rod would become loose, is axially provided on one end face of the rotation stopping sleeve (2) in a projecting manner. The parent body (14) and the appendage body (15) are fastened and connected to each other via the screw rod (1). The rotation stopping sleeve (2) is installed outside a rotation-stopping resisting portion (5) of the screw rod (1). The rotation stopping boss (11) of the rotation stopping sleeve is inserted into a rotation stopping hole (17) of the appendage body. The rotation stopping boss (11) of the rotation stopping sleeve is resisted by the rotation stopping hole (17) of the appendage body on a side in the direction in which the screw rod would become loose, and the screw rod (1) penetrates a rotation stopping through hole (9) so as to jointly restrain the rotation stopping sleeve (2) from rotating relative to the appendage body (15). A screw-rod rotation stopping portion (8) cooperates with an inner rotation-stopping portion (10) of the rotation stopping sleeve (2) so as to restrain the rotation-stopping resisting portion (5) from rotating relative to the rotation stopping sleeve (2). The present invention has the advantages of not requiring a rotation stopping piece and the machining of a rotation stopping hole on the appendage body. The rotation stopping sleeve is quick, convenient, and reliable to install and remove. The screw rod cannot rotate in reverse and become loose.
