Abstract

The utility model discloses a double-seal drill rod, which comprises a drill rod body, wherein a female buckle is arranged at the left end of the drill rod body, a male buckle is arranged at the right end of the drill rod body, both the male buckle and the female buckle are provided with threads, and the threads on the male buckle are matched with the threads on the female buckle; the utility model has the advantages of reasonable design, convenient to use can effectively improve the leakproofness of drilling rod to prevent that the exploration in-process normal water from the inside of joint gap infiltration drilling rod.

Description

Double-sealing drill rod

Technical Field

The utility model belongs to the technical field of the exploration equipment and specifically relates to a double containment drilling rod is related to.

Background

The drilling rod is often required to be used in the geological exploration process for exploration and excavation, and the sealing performance of the gap between the traditional drilling rod and the assembled connection is poor, so that water is often infiltrated into the drilling rod from the gap due to external pressure in the exploration and excavation process, and the long-term use of the drilling rod is not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem of coming, provide a dual-seal drilling rod for this reason, including the drilling rod body, the left end of drilling rod body is provided with the box, the right-hand member of drilling rod body is provided with the pin thread, all be provided with the screw thread on screw thread and the pin thread on pin thread and the box and screw thread phase-match, the port position department and the root position department of pin thread all are provided with chamfer a, chamfer a's inclination is 15 degrees.

Preferably, chamfers a are also provided at the port position and the root position of the box.

The utility model has the advantages that: the utility model has the advantages of reasonable design, convenient to use can effectively improve the leakproofness of drilling rod to prevent that the exploration in-process normal water from the inside of joint gap infiltration drilling rod.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a partial structural schematic diagram of the present invention;

FIG. 3 is a schematic view of a section structure of the drill rod assembly of the present invention;

in the figure: 1. a drill rod body; 2. a male buckle; 3. and (4) a female buckle.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The double-seal drill rod shown in fig. 1, 2 and 3 comprises a drill rod body 1, wherein a female buckle 3 is arranged at the left end of the drill rod body 1, a male buckle 2 is arranged at the right end of the drill rod body 1, threads are arranged on the male buckle 2 and the female buckle 3, the threads on the male buckle 2 are matched with the threads on the female buckle 3, chamfer angles a are arranged at the port position and the root position of the male buckle 2, and the inclination angle of the chamfer angle a is 15 degrees.

Chamfers a are also arranged at the port position and the root position of the female buckle 3.

In the using process, the male buckle 2 of one drill rod body 1 and the female buckle 3 of the other drill rod body 1 are screwed and screwed mutually through threads, so that the drill rods are assembled; the setting of chamfer a can close the back soon at pin thread 2 and box 3 for pin thread port and box root position department of contacting and pin thread root and box tip position department of contacting are sealed inseparabler, thereby effectively play the inside effect of preventing water infiltration drilling rod.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
