Abstract
The utility model relates to a drill pipe which comprises a drill pipe body. An inner threaded end part and an outer threaded end part are respectively arranged at two ends of the drill pipe body. The drill pipe is characterized in that the a connection part of the inner threaded end part and the drill pipe body is thicker than the drill pipe body, and a bar-shaped rib body parallel to an axis of the drill pipe body is arranged on the drill pipe body. The drill pipe has the advantages of being small in thickness of the drill pipe body, light in weight, and reliable in intensity.
Description
Technical field
The utility model belongs to the drilling equipment technical field, particularly relates to a kind of drilling rod.
Background technology
Drilling rod be connect drill bit in the drilling tool, in order to the rod member of transferring power, be mainly used in the fields such as hydrogeologic prospecting, well and oil drilling.Drilling rod mainly is comprised of drill pipe body, internal threaded end, external screw thread end, and internal threaded end and male end section are located at respectively the two ends of drill pipe body, and internal threaded end and external screw thread end on two drilling rods can be equipped with, and realize the connection of two drilling rods with this.In order to guarantee the force intensity that is subjected to of drilling rod, require drill pipe body must have certain thickness, the excessive drill pipe body of thickness can increase overall volume and the weight of drilling rod, is not easy to transportation and the dismounting of drilling rod.
Summary of the invention
A kind of body thickness is little, lightweight, the reliable drilling rod of intensity for the technical problem that exists in the solution known technology provides for the utility model.
The utility model for the skill that exists in the solution known technology, the technical scheme that the art problem is taked is: a kind of drilling rod, the two ends that comprise drill pipe body, described drill pipe body are respectively equipped with internal threaded end and external screw thread end, it is characterized in that: the thickness at the handing-over position of described internal threaded end and described drill pipe body is greater than the thickness of described drill pipe body, and described drill pipe body is provided with the muscle body of the strip parallel with the axis of drill pipe body.
The utility model can also adopt following technical scheme:
The thickness of described external screw thread end is less than described drill pipe body, and the junction of described external screw thread end and described drill pipe body is provided with shoulder.
Described drill pipe body, internal threaded end, external screw thread end and muscle body are one of the forming.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, be provided with the muscle body at drill pipe body, the muscle body is strip muscle body.The order of this structure can suitably reduce drill pipe body thickness under the prerequisite that has guaranteed drilling rod intensity, with diameter and the weight that reduces drilling rod, make drilling rod more be convenient to transportation and dismounting.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, drill pipe body; 2, internal threaded end; 3, external screw thread end; 4, muscle body; 5, sealing ring.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of drilling rod.Comprise drill pipe body 1, internal threaded end 2 and external screw thread end 3, wherein the two ends of drill pipe body 1 are located at respectively in internal threaded end 2 and external screw thread end 3, and drill pipe body 1 is provided with the muscle body 4 of strip, and the muscle body 4 of strip is parallel to the axis of drill pipe body 1.Under the prerequisite that guarantees drilling rod intensity, the thickness of drill pipe body 1 is little in this structure, and the diameter of drilling rod is little, lightweight, and drilling rod is convenient to transportation and dismounting.
Above-mentioned internal threaded end 2 is the position that the drilling rod working stress is concentrated the most with the handing-over position of drill pipe body 1, and in the utility model, the thickness at this position further guarantees the intensity of drilling rod greater than the thickness of drill pipe body.
The thickness of external screw thread end 3 is less than drill pipe body, external screw thread end 3 is provided with shoulder with the junction of drill pipe body 1, and when the internal threaded end in two drilling rods and external screw thread end are equipped, but youngster sets up sealing ring 5 on the shoulder, improve the sealing performance of drilling rod, avoid the drilling rod internal pressure loss.
Above-mentioned embodiment only is to functional descriptions of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model all drop within the protection domain of the present utility model.
Claims (3)
