Fastening connection assembly, fastening connection structure and rail structure

Abstract

Disclosed is a fastening connection structure. The fastening connection structure comprises a fastening connection assembly, a parent body and an appendage. The fastening connection assembly comprises a screw and a screw rotation stop sleeve. The hole wall of a rotation stop through hole of the screw rotation stop sleeve is provided with an axial screw rotation stop sleeve inner rotation stop part matched with a resisting part outer rotation stop part of the screw. A screw rotation stop sleeve rotation stop convex part is arranged on the periphery of the screw rotation stop sleeve. The appendage is provided with an appendage rotation stop convex part. The screw connects the parent body with the appendage together in a fastening mode. The resisting part outer rotation stop part and the screw rotation stop sleeve inner rotation stop part restrain the screw from rotating relative to the screw rotation stop sleeve in a resisting matched mode. The appendage rotation stop convex part resists the screw rotation stop sleeve rotation stop convex part circumferentially on one side of the screwed-in direction of the screw so as to restrain the screw rotation stop sleeve from rotating relative to the appendage in a matched mode. The screw, the appendage and the parent body are installed together non-rotationally. The fastening connection structure has the advantages that a rotation stop part is not needed, a rotation stop hole does not need to be machined in the appendage, installation and taking-out of the rotation stop sleeve are fast, convenient and reliable, and the screw does not rotate reversely or get loose.

Description

[0001] Technical field: [0002] The invention relates to a fastening connection technology for statically connecting two or more objects with threaded pairs; in particular, it relates to a method for statically connecting crankshaft linkage mechanisms, track structures, aircraft, ships, equipment, aerospace equipment, etc. through threaded pairs. Aircraft carrier, spaceship, rocket, engine, nuclear reaction equipment, train, high-speed rail, rail, steel structure building, steel structure bridge, automobile, etc. Fastening connection components and fastening connection structures and tracks of mechanical parts on key parts of mechanical equipment structure, the use environment of these mechanical parts is particularly harsh, such as large vibration, high temperature environment, heavy load, etc., and the connection reliability of the threaded mechanical static connection is particularly high. Background technique [0003] The thread pair mechanical static connection between o...

Problems solved by technology

[0015] Aiming at the problems existing in the prior art, the technical problem to be solved by the present invention is to overcome the existing anti-loosening technical solution that the anti-rotation sleeve is used to limit the reverse loosening of the threaded pair by those skilled in the art, because the anti-rotation sleeve is very Difficult or impossible to remove from the first anti-rotation hole, resulting in useless inertial thinking, providing a screw that will not be loosened due to reverse rotation and does not require disassembly tools, and the detachment of the anti-rotation sleeve is fast, convenient and reliable The fastening connection components and fastening connection structure, track structure
