Preferably, the sealing washer has been cup jointed through the screw thread at the top of screw pole surface, the oil feed tank has been seted up to the surface of sealing washer, the fixed intercommunication in inside of oil feed tank has into oil pipe, the internal thread that advances oil pipe has cup jointed the screw valve, through having seted up the oil feed tank, utilizes the internally mounted of oil feed tank to have into oil pipe to with lubricating oil through advancing oil pipe and feeding to the surface of screw pole, then will advance oil pipe closure through the screw rotation utilizing the screw valve, thereby prevent dust and water through advancing the surface that oil pipe got into the screw pole.
Preferably, the diameter of the sealing ring has a value greater than the diameter of the turn, when the diameter of the sealing ring has a value greater than the turn, so that the turn is located inside the sealing ring.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. this combination formula self tapping nut, set up hollow groove through the inside both sides at self tapping nut, through be equipped with the fixture block with the lead screw both sides, through upwards joint into hollow groove with lead screw both sides fixture block, thereby with the lead screw joint in self tapping nut's inside, then utilize the helicoid of the circle of screw spiral removal and joint inside self tapping nut, thereby fix self tapping nut and lead screw, thereby can advance the self tapping nut of looks adaptation through the joint of different lead screws, the advantage of changing different self tapping nuts has been realized, the practicality has been improved.
2. This combination formula self-tapping nut, through having seted up the oil feed tank at the surface of sealing washer, advance oil pipe and screw valve, the medial surface that utilizes the sealing washer is equipped with the internal thread, pass through the screw pole rebound with the sealing washer through the screw rotation, thereby cover the gap at self-tapping nut top, when the sealing washer is ageing, through rotatory screw valve, remove the closure to advancing oil pipe, carry the surface of advancing the screw pole with lubricating oil through advancing oil pipe and oil feed tank, thereby make the screw pole can rotate out, dismantle and change the sealing washer, thereby self-tapping threaded life has been improved.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, a combined self-tapping nut includes a self-tapping nut 1 and a screw rod 2, hollow grooves 4 are formed in both sides of an inner wall of the self-tapping nut 1, fixture blocks 5 are fixedly connected to both sides of an outer surface of a top of the screw rod 2, the screw rod 2 is fixedly clamped in the hollow grooves 4 through the fixture blocks 5, the screw rod 2 is located inside the self-tapping nut 1, a top thread of the screw rod 2 is sleeved with a thread ring 3, and the thread ring 3 is located below the self-tapping nut 1.
