    • PROBLEM TO BE SOLVED: To provide a joint structure for directly connecting a plurality of pipes. SOLUTION: A first pipe 10 has: a connection end face 11 for which laser machining is applied at a predetermined angle to an axis; and tenons 12 formed in the connection end face. A second pipe 20 has a connection end face 21 for which laser machining is applied at a predetermined angle to an axis and mortises 22 formed in the connection end face. The joint structure of the two pipes 10, 20 is formed by fitting the tenons 12 of the first pipe 10 in the mortises 22 of the second pipe 20. Surface contact of the connection end face 11 of the first pipe 10 and the connection end face 21 of the second pipe 20 is made with whole wall thickness of the pipes. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种用于直接连接多个管道的接头结构。 解决方案:第一管10具有:以与轴成预定角度施加激光加工的连接端面11; 榫头12形成在连接端面上。 第二管20具有连接端面21,激光加工以预定的角度施加在轴线上,并且形成在连接端面上的榫眼22。 通过将第一管10的榫头12装配到第二管20的榫眼22中,形成两根管10,20的接合结构。第一管10的连接端面11与连接端面 第二管20的21由管的整个壁厚制成。 版权所有(C)2007,JPO&INPIT
