Example Embodiment

[0023]Example 1:

[0024]As attachedFigure 1-Figure 3As shown, the present invention discloses a preferred embodiment of an anti-loosening fastening nut washer assembly, including a nut 1 and a washer 6. The nut 1 is a regular hexagonal prism, and the middle of the nut 1 has a circular screw hole. 5. The inner wall of the screw hole 5 is provided with threads, and the inner wall of the end of the screw hole 5 is provided with a connecting ring 4 extending upward; the nut 1 is movably connected to the washer 6 through the connecting ring 4. The top and bottom of the side edges of the nut 1 are provided with chamfers.

[0025]The top of the nut 1 is provided with six locking protrusions 2, and the top of the nut 1 is provided with six middle locking protrusions 3, the middle locking protrusions 3 and the locking protrusions 2 are arranged alternately. , The six locking protrusions 2 are symmetrically arranged along the axis of the nut 1, the upper surface of the locking protrusion 2 is an i...

Abstract

The invention discloses an anti-loosening fastening nut and gasket assembly which comprises a nut and a gasket. The nut is movably connected with the gasket; the nut is in a regular hexagonal prism shape; a round screw hole is formed in the middle of the nut; a thread is arranged on the inner wall of the screw hole, and a connecting ring is arranged on the inner wall of the end portion of the screw hole in an upward extending mode; and six locking protrusions are arranged at the top of the nut, and the six locking protrusions are symmetrically arranged along the center of the axis of the nut.The anti-loosening fastening nut and gasket assembly can effectively resist the harm phenomena of rotation, loosening, tripping deformation and the like of a fastening piece continuously in high-temperature, high-pressure, high-frequency and strong-vibration impact environments for a long time, and achieves excellent safe and reliable movable connection; by arranging more middle locking protrusions, the cross sectional area of a non-return stress surface is improved, and the fastness of the nut is improved; by arranging a plurality of non-return protrusions connected end to end, the strength of a non-return part of the working face can be improved, and the anti-loosening effect is improved.

Description

technical field [0001] The invention relates to the field of nut washer, in particular to an anti-loosening fastening nut washer assembly. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials. several types. Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specification can be connected together through internal threads. The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic load. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. Among them, the use of lock nuts is one of the anti-loosening measures. [0003] Th...
