Abstract
The utility model relates to an equilateral fillet triangular drill rod, and belongs to the field of drill rods. The drill rod comprises an inner connecting end, an outer connecting end and a rod body, wherein the outer contour sections of the inner connecting end, the outer connecting end and the rod body are triangular; arc-shaped bevels are arranged at the three corners of the triangle; a connecting hole is formed in the inner connecting end; a connecting lug boss is arranged on the outer connecting end; connecting internal threads are formed in the connecting hole; connecting external threads are formed in the connecting lug boss; the connecting hole and a breather pipe penetrating the connecting lug boss are formed in the rod body; and a plurality of strips of grooves are formed in the side rod surface of the rod body. Through the adoption of the thread structure of the internal threads and the external threads to strengthen the stability of the connecting structure, the deslagging quantity of the breather pipe is increased by combining the thread tooth-shaped structure; and through the adoption of the structure integrally formed by the inner connecting end, the outer connecting end and the rod body, the strength is improved; so that the problems of serious breaking and unsmooth deslagging when the drill rod is in use are solved.

The utility model content
The utility model is in order to improve the problem that breakage problem is serious and deslagging has some setbacks in the use of triangle drilling rod, a kind of equilateral fillet triangle drilling rod that can connective stability is strong, the effective intensity of deslagging is high is provided, to achieve these goals, the technical solution of the utility model is as follows:
A kind of equilateral fillet triangle drilling rod, connect end, external connection end and the body of rod in comprising, and in to connect the outline cross section of end, external connection end and the body of rod triangular in shape, and leg-of-mutton three angles are provided with arc angling, connect end in described and be provided with connecting hole, external connection end is provided with the connection boss, and be provided with the connection internal thread in the described connecting hole, described connection boss is provided with the connection external screw thread, offer a connecting hole and run through the ventilating pipe that is connected boss at the body of rod, and body of rod side direction pole face is provided with many grooves.
In above-mentioned a kind of equilateral fillet triangle drilling rod, described connecting hole be connected boss for being trapezoidal, and described internal thread and external screw thread are for being trapezoidal thread.
In above-mentioned a kind of equilateral fillet triangle drilling rod, described trapezoidal thread is that an oblique angle is that another oblique angle, right angle is the trapezoidal thread of 58-62 degree.
In above-mentioned a kind of equilateral fillet triangle drilling rod, described external screw thread and internal thread are the trapezoidal thread of 3-3.5 tooth/inch.
In above-mentioned a kind of equilateral fillet triangle drilling rod, the tooth height of described trapezoidal thread is 2-2.1mm.
In above-mentioned a kind of equilateral fillet triangle drilling rod, it is one-body molded to connect end, external connection end and the body of rod in described.
In above-mentioned a kind of equilateral fillet triangle drilling rod, connect the arc angling in end, external connection end outline cross section greater than the arc angling in body of rod outline cross section in described.
The beneficial effect that the utlity model has: the stability of having strengthened its syndeton by internal thread and externally threaded helicitic texture, improve the bed drain purge of ventilating pipe in conjunction with its form of thread structure, improve its intensity by interior end, external connection end and the body of rod integrated formed structure of connecing again, and then solved its problem that in use breakage problem is serious and deslagging has some setbacks.
