Abstract
The invention relates to a reinforced type drill rod inner-thread protection sleeve which comprises a protection sleeve body (1) and an inner ring (2). The inner ring (2) is embedded into the protection sleeve body (1), two grooves (3) are formed in the opening position above the protection sleeve body (1), and connecting holes (4) are formed in the surface of each of the grooves (3). An air vent (5) is formed in the bottom of the protection sleeve body (1). Multiple threads (6) and multiple fixing holes (7) are formed on/in the outer wall of the protection sleeve body (1). The inner ring (2) is annular, and multiple mesh holes (8) are formed in the surface of the inner ring (2). The fixing holes (7) in the outer wall of the drill rod inner-thread protection sleeve facilitate the fixation of the inner ring via an ejection pin, plastic pouring is facilitated, the consistent wall thickness of the protection sleeve is also ensured, and moisture and scraps in a drill rod can be discharged through the air vent.
Description
Technical field
The present invention relates to a kind of enhancement mode drilling rod internal thread protective sleeve.
Background technology
Drilling rod connects drill bit in boring bar tool, in order to transmit the rod member of power.Connection between drilling rod is very general, so aobvious particularly important of protective sleeve.At present, general drilling rod protective sleeve does not have steam vent due to bottom, so moisture in drilling rod and scrap are difficult to drain, will affect the quality of oil in drilling rod like this; The protective sleeve variable thickness produced in addition causes, very inconvenient when installing in drilling rod, very improper.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and ensure that protective sleeve wall thickness is consistent and the moisture of draining in drilling rod and scrap can enhancement mode drilling rod internal thread protective sleeves.
The object of the present invention is achieved like this:
A kind of enhancement mode drilling rod internal thread protective sleeve, comprise protective sleeve body and inner ring, described inner ring is embedded in protective sleeve body, and the upper opening place of described protective sleeve body is provided with twice groove, and per pass groove surfaces is equipped with connecting hole; The bottom of described protective sleeve body is provided with air-vent; The outer wall of described protective sleeve body is provided with multiple tracks screw thread and multiple fixing hole; Described inner ring in the form of a ring, is provided with multiple mesh on the surface of inner ring.
Compared with prior art, the invention has the beneficial effects as follows:
The fixing hole of enhancement mode drilling rod internal thread protective sleeve outer wall of the present invention facilitates thimble to fix inner ring, is convenient to water injection molding material, also ensure that the wall thickness of protective sleeve can be consistent, and air-vent can be drained moisture in drilling rod and scrap in addition.

Detailed description of the invention
See Fig. 1-Fig. 3, enhancement mode drilling rod internal thread protective sleeve of the present invention, comprise protective sleeve body 1 and inner ring 2, described inner ring 2 is embedded in protective sleeve body 1, and described protective sleeve body 1 adopts plastic pouring to form.
The upper opening place of described protective sleeve body 1 is provided with twice groove 3, and per pass groove 3 surface is equipped with connecting hole 4; The bottom of described protective sleeve body 1 is provided with air-vent 5; The outer wall of described protective sleeve body 1 is provided with multiple tracks screw thread 6 and multiple fixing hole 7.
Described inner ring 2 in the form of a ring, is provided with multiple mesh 8 on the surface of inner ring 2.
Mesh 8 is convenient to water injection molding material outside inner ring 2, adopts thimble can fix inner ring 2 easily by fixing hole 7, enables the wall thickness of protective sleeve body 1 consistent.
