Title:
FASTENING CONNECTION STRUCTURE, FASTENING CONNECTION ASSEMBLY AND CRANKSHAFT CONNECTING ROD MECHANISM
Document Type and Number:
WIPO Patent Application WO/2018/039948
Kind Code:
A1
Abstract:
Disclosed is a fastening connection structure, comprising a fastening connection assembly, a parent body (16) and an appendage body (17). The fastening connection assembly comprises a screw rod (1), a locknut (2) and a rotation stopping sleeve (3). A rotation stopping boss (14) of the rotation stopping sleeve, for restraining the rotation stopping sleeve (3) 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 (3) in a projecting manner. The parent body (16) and the appendage body (17) are fastened and connected to each other via the screw rod (1) and the locknut (2). The rotation stopping sleeve (3) is installed outside the locknut (2); the rotation stopping boss (14) of the rotation stopping sleeve is inserted into a rotation stopping hole (22) of the appendage body; and the rotation stopping sleeve (3) is axially limited outside the locknut (2). The rotation stopping boss (14) of the rotation stopping sleeve is resisted by the rotation stopping hole (22) of the appendage body on a side in the direction in which the locknut would become loose so as to restrain the rotation stopping sleeve (3) from rotating relative to the appendage body (17). The parent body (16) and the appendage body (17) are fastened and connected to each other via the screw rod (1) and the locknut (2) in a non-rotatable manner. 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.
