Abstract

The invention discloses a retaining and anti-loosening combined nut. The retaining and anti-loosening combined nut comprises a main nut, a movable ring, a pressing ring, side grooves and protruding strips, a mounting groove with an upward opening is formed in the main nut, a main threaded hole is formed in the bottom of the mounting groove, the inner diameter of the mounting groove is larger thanthe inner diameter of the main threaded hole, the mounting groove and the main threaded hole are coaxial with the main nut correspondingly, a plurality of vertically-arranged side grooves are formed in the side wall of the mounting groove and extend downwards to the bottom of the mounting groove from the top of the mounting groove, the movable ring is arranged in the mounting groove, the thicknessof the movable ring is smaller than the depth of the mounting groove, a plurality of protruding strips in one-to-one correspondence with the side grooves are arranged on the outer wall of the movablering, the protruding strips are embedded into the side grooves, and an internal thread is arranged on the inner wall of the movable ring. According to the retaining and anti-loosening combined nut, the pressing ring is matched with the movable ring, so that the main nut and a screw rod can be locked through the pressing ring after being tightened, and the combined nut has good retaining and anti-loosening performance.

Description

【Technical field】 [0001] The invention relates to the technical field of fasteners, especially the technical field of nuts. 【Background technique】 [0002] Nut is a commonly used fastener with a wide range of applications. For different occasions, the requirements for nuts are also different. In some occasions, we need the nut to have a good anti-retraction and anti-loosening effect to ensure the effectiveness of the connection. The effect of the existing anti-back and anti-loosening nuts is not ideal enough, and cannot well meet the demand. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a combined anti-backward and anti-loosening nut, which can make the nut have good anti-backward and anti-loosening performance. [0004] In order to achieve the above object, the present invention proposes a combined anti-retraction and anti-loosening nut, including a main nut, a movable ring, a pressure ring, ...
