The invention discloses a straight sleeve and relates to the field of automobile spare parts. The straight sleeve comprises a sleeve body. The outer diameter surface of the sleeve body is provided with an inwards-concaved rotary groove, one end of the rotary groove is the installation end, and the other end of the rotary groove is the matching end. The outer diameter size of the installation end is smaller than the outer diameter size of the matching end. An installation hole is formed in the installation end in the axial direction. A matching hole is formed in the matching end in the axial direction. A plurality of installation grooves are formed in the rotation inner wall of the installation hole and are evenly distributed on the circumferential face. Angles between the connected installation grooves are the same. The installation grooves and the rotary groove are located at the same axial height. According to the straight sleeve, connecting deformation of a connecting part in the butt-joint process can be avoided, and the connecting sleeve is high in manufacturing precision, convenient to install and uninstall, high in matching tightness, reliable and durable.
Description
technical field [0001] The invention relates to the field of auto parts processing, in particular to a straight sleeve. Background technique [0002] In the electrical circuit connection of automobiles, the shaft parts are generally connected by docking each other. In order to improve the safety of the connection between structures and avoid breakage due to weak butt joints, tubular parts are usually used at two or more connections. The sleeve is closed butt joint. After the interconnected parts of the structures are inserted into the sleeves, it is necessary to use a pressure device to connect and fix them on the sleeves, which leads to operational complexity in connection and disassembly of the structures. Moreover, the deformation of the sleeve is very easy to cause the connection part to loosen and fall off. Contents of the invention [0003] The main technical problem to be solved by the invention is to provide a straight sleeve, which has a reasonable design and a ...
