Detailed Description
In order to make the creation features, technical means and achievement objects of the present invention easy to understand, the following description further explains embodiments of the present invention with reference to specific embodiments.
As shown in fig. 1-3, a drill pipe reducer union with adjustable diameter comprises a reducer knob 1, a reducer union sleeve 2, a push rod 3 and a connecting sleeve head 5; the reducing knob 1 comprises a first connecting rod 11, a fixing ring 12 and a connecting ring 13, one end of the first connecting rod 11 is connected with the outer periphery of the fixing ring 12, the other end of the first connecting rod is connected with the inner periphery of the connecting ring 13, a push rod 3 is fixed in the fixing ring 12, and the outer part of the connecting ring 13 is in threaded connection with the inner periphery of the reducing joint sleeve 2; the left side of the pushing rod 3 is cylindrical, the right side of the pushing rod is conical, threads are carved on the outside of the cone, and the fixing ring is fixedly connected with the left side cylinder; connecting sleeve head 5 includes second connecting rod 51, elastic ring 52 and arc connection iron 53, and second connecting rod 51 one end is connected with elastic ring 52 periphery, and one end is connected with arc connection iron 53 internal week, and elastic ring 52 internal week is connected with the right side circular cone end of push rod 3.
Preferably, the arc-shaped connecting iron 53 is externally threaded, so that the connection with the adapting drill rod or the drill bit 4 through threads can be realized, and the connection stability is improved.
Preferably, the cylinder on the left side of the push rod 3 is connected with the middle opening of the reducing knob 1 through a thread or a key.
