Abstract

The invention discloses a locknut structure. The locknut structure comprises a nut body, wherein the nut body is provided with a threaded hole penetrating through the nut body in the axial direction;a cone-shaped ring groove concaved upward is arranged at the position, at the outside in the radial direction of the threaded hole, of the bottom end of the nut body; an open north penetrating throughthe radial direction is arranged at the sidewall in the radial inner side of the cone-shaped ring groove; the locknut structure further comprises a washer portion; the washer portion comprise a washer body; a washer frustum protruding upward is arranged on the washer body; and the washer frustum can be buckled in the cone-shaped ring groove and pushes the sidewall, at inner side in the radial direction, of the cone-shaped ring groove to shrink in the radial direction. According to the locknut structure, the problems that the use occasions in the prior art are limited, the reliability is poor,and the structure is complicated are overcome; and the axial force and the radial force are synchronously used by the locknut structure to solve the problem of loose, the locknut structure is simplein structure, convenient to install, high in applicability and beneficial to promote.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to an anti-loosening nut structure. Background technique [0002] In municipal facilities construction projects, the use of nuts is involved in many places, ranging from the installation of bridges, the connection of rails, the assembly of various prefabricated components, the structural beams and columns of buildings, to the installation of supports and hangers in pipeline laying. Use, installation of pipe brackets, connection of equipment and foundation, etc., it can be said that nuts are everywhere, and problems such as equipment maintenance and equipment replacement caused by "loosening" during operation abound. [0003] The anti-loosening measures for ordinary threaded connections generally include spring washers, double nuts, metal lock washers, lock nuts, toothed lock washers, nylon insert locking, slotted nuts, cotter pins, stop washers, wedge pressure Tight, d...
