Abstract
The invention relates to a tool joint provided with an all-steel protecting cap, and is characterized by comprising a joint body (1), wherein a protecting cap (2) is sleeved on one end of the joint body (1), the protecting cap (2) is connected to an external thread through an internal thread of the joint body (1), and a rubber gasket (3) is further arranged between the protecting cap (2) and the joint body (1). According to the tool joint provided with the all-steel protecting cap, the protecting cap, which is made of all-steel, is arranged on one end of the joint body, so that abrasion of a drill rod in a transport process can be avoided, and furthermore, the rubber gasket is arranged between the protecting cap and the joint body, so that tightness of the toll joint is ensured, and the tool joint is not easyto leak oil.
Description
Technical field
The present invention relates to a kind of tool joint with all steel protective cap.
Background technology
In the drilling process of oil, natural gas, water source and mineral reserve, all need to use drilling rod, an end of drilling rod is connected with joint, although the structure of tool joint is simple, its quality requirement that will reach is higher.Usually tool joint easily is worn in transportation, thereby causes can't normally connecting between drilling rod, even causes security incident.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of not easy to wear, the tool joint with all steel protective cap that sealing is strong.
The object of the present invention is achieved like this:
The tool joint of band all steel protective cap of the present invention, comprise joint body, and an end cover of described joint body has protective cap, and described protective cap is connected with the external screw thread of joint body by its internal thread, also is provided with rubber washer between described protective cap and joint body.
The tool joint of band all steel protective cap of the present invention has the following advantages:
The tool joint of band all steel protective cap of the present invention adds at an end of joint body the protective cap that all steel is made; so just, can avoid drilling rod to be worn in transportation; and increase rubber washer between protective cap and joint body, guaranteed the sealing of tool joint, not easy oil leakage.
Description of drawings
Fig. 1 is the structural representation of the tool joint of band all steel protective cap of the present invention.
In figure: joint body 1, protective cap 2, rubber washer 3.
The specific embodiment
Referring to Fig. 1; the present invention relates to a kind of tool joint with all steel protective cap; comprise joint body 1; one end cover of described joint body 1 has protective cap 2; can avoid drilling rod to be worn in transportation, described protective cap 2 is connected with the external screw thread of joint body 1 by its internal thread, also is provided with rubber washer 3 between described protective cap 2 and joint body 1; this rubber washer 3 has guaranteed the sealing of tool joint, makes its not easy oil leakage.
