Beschreibung
Zusammenfassung:	The invention discloses a pulling-prevention rod thread gluing combined nut for a fracturing pump, and belongs to the technical field of fracturing pump hydraulic end supporting devices. The pump comprises a pump box and a pull rod, the pull rod is connected to the outer side of the pump box, the pull rod is sleeved with a tensioning nut in a thread manner, the inner thread of the tensioning nut is matched with the pull rod, the outer thread of the tensioning nut is matched with the locking nut, a locking gasket is arranged between the locking nut and the pump box, the tensioning nut is sleeved with the locking gasket, the locking gasket is in spline connection with the tensioning nut, one end of the locking gasket is attached to the outer wall of the pump box, the other end of the lockinggasket is attached to the locking nut, the manner that a traditional fracturing pump pull rod is dismounted by one tensioning nut is changed into combination of the tensioning nut and the locking nutto achieve tensioning of
