Document Type and Number:
WIPO Patent Application WO/2023/165306
Kind Code:
A1
Abstract:
Provided in the present application are a nut structure and an electric valve, the nut structure comprising: a nut body; a limiting structure protrudingly arranged on the outer circumferential surface of the nut body, the limiting structure having a stop face and a mating face; a spiral guide groove arranged on the outer circumferential surface of the nut body, the spiral guide groove being positioned on the side of the limiting structure with the mating face, and one end of the spiral guide groove taking the mating face as a starting point or taking the direction of extension of the mating face as a starting point; and a stop ring rotatably arranged in the spiral guide groove, the stop ring having a stop fit with the stop face. Using the present solution, during installation of the stop ring in the nut body, the mating face guides the installation of the stop ring, and the end of the stop ring closest to the spiral guide groove can directly enter the spiral guide groove in the direction of extension of the mating face, improving the installation precision and the installation efficiency of the stop ring. The stop ring has a stop fit with the stop face in order to limit the range of movement of the stop ring on the spiral guide groove, ensuring the reliability of the nut structure.
