The utility model relates to a sucker rod centralizer, which comprises an upper nozzle, a wear-resistant sleeve, a sealing sleeve, a lower nozzle and a threaded sleeve. The right surface of the upper nozzle is installed on the left surface of the wear-resistant sleeve and is located on the same axis. The upper nozzle has a cylinder structure of 3CM and 5CM high, and the wear-resistant sleeve is embedded on the left surface of the sealing sleeve and adopts an interval sleeve. The lower nozzle is a cylindrical structure with a diameter of 2CM and a height of 3CM. The utility model relates to a sucker rod centralizer, in which the thread sleeve is aligned with the sucker rod and rotated tightly, and the upper nozzle is connected with a centralizer. The wear-resistant sleeve radius is larger than the sucker rod when the sucker rod is working, and the sucker rod can not hit the inner wall. When the wear-resistant layer is replaced, the sucker rod rod is rotated by rotating ring, which drives the second rotating shaft The column moves, the transmission connecting column pushes the limit block outward, the limit block pushes the wear-resisting layer outward, separates the wear-resisting layer from the limit block, and replaces the new wear-resisting layer with the sealing edge sleeve. When replacing the wear-resisting sleeve, the disassembly is more convenient and the practicability is higher.
