摘　　要：通常螺纹只能在轴向有作用力,压紧或者拉紧两物件。本文介绍了一种在轴向和径向双向同时具备约束力的自锁螺纹,此螺纹特点是在径向也能拉紧或者压紧两物件。同时介绍了利用这种自锁螺纹进行接缝连接的方法,自锁螺纹螺杆旋入设置自锁螺纹的两物件接缝处,以通过螺杆的自锁螺纹与工件的自锁螺纹之间的连接实现螺杆与物件的连接。Usually the thread can only apply an axial force to compress or tighten two objects.This article introduces a self-locking thread that has binding force in both axial and radial directions.The feature of this thread is that it can also tighten or compress two objects in the radial direction.At the same time,this article also introduces the method of using self-locking threads with both axial and radial constraints for joint connection.The self-locking thread screw is screwed into the joint of two objects with self-locking threads to achieve the connection between the self-locking thread of the screw and the self-locking thread of the workpiece.
