The invention discloses a high-strength firm trapezoidal nut facilitating oil injection. The nut comprises a nut body, a fixed ring, a movable ring, a sleeve, an oil injection hole, a hole-sealing body and an oil seepage hole, wherein the nut body is a transversely arranged cylindrical body, the left and right ends of the nut body are open, a trapezoidal thread is arranged on the inner wall of thenut body, the nut body is externally sleeved with the sleeve coaxial with the nut body, the fixed ring is fixed to the left side of the sleeve, the fixed ring is fixed to the side wall of the nut body, the sleeve, the nut body and the fixed ring define an oil storage cavity with an opening on the right side, the outer wall close to the right end of the nut body is provided with external threads,the inner wall of the movable ring is provided with internal threads matched with the external threads, the movable ring is screwed on the nut body, and the movable ring seals the opened end of the right end of the oil storage cavity. According to the nut, the oil storage cavity is arranged outside the nut body, so that more oil can be stored in the trapezoidal nut, and the trapezoidal nut can beeffectively lubricated.
Description
【Technical field】 [0001] The invention relates to the technical field of mechanical parts, especially the technical field of trapezoidal nuts. 【Background technique】 [0002] The trapezoidal nut is a commonly used drive nut, which is often matched with the screw. The trapezoidal nut needs to be lubricated during use, if the lubrication is not enough, it is easy to damage the nut and the screw rod matched with it. The lubricating effect of the existing trapezoidal nut is not ideal enough. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a high-strength and firm trapezoidal nut that is convenient for oil filling, which can make the trapezoidal nut easy to oil and make the trapezoidal nut have good lubricating performance. [0004] In order to achieve the above object, the present invention proposes a high-strength firm trapezoidal nut that is convenient for oil injection, including a nut body, a fix...
