Summary:The utility model relates to a diameter variable screw thread pair connecting device, comprising a middle standing pillar, a head beam, a diameter variable nut, a base and a connection stud; the middle standing pillar, fixed through the connection stud and the diameter variable nut, is arranged between the head beam and the base; the internal screw-thread of the diameter variable screw thread pair is a diameter variable nut with higher dedendum as well as conical dedendum path, and the external screw-thread is a stud with circle arc dedendum and the hardening treated tooth surface; when the crew thread pair receives a bigger alternating impact load, due to the heightener of the dedendum deformation, which enables the screw thread pair in good self locking performance, the mechanical linkage in high intensity without looseness, and the effective length of screw thread pair engagement is added. The utility model has the advantages of simple structure, low cost, high intensity mechanical linkage, visible self locking performance; the ability to endure the alternating impact load enhances more than three times.
