Description
Technical field
This utility model relates to engineering drilling, mine locating drilling tool accessory field, coal seam, is exactly specifically that a kind of MQT combines extension bar.
Background technology
In coal drilling process, extension bar is needed to carry out operation, need between extension bar and extension bar to be attached, realize the exploitation of deep coal, in extension bar connection procedure, connective stability between two extension bars has influence on work efficiency and the service life in later stage, being connected instability between extension bar with extension bar can cause extension bar in later stage drilling process to loosen, between extension bar and extension bar, attachment force is excessive, extension bar phenomenon of rupture is there will be, thereby ensure that effectively connecting between extension bar is important step during coal drilling well in drilling process.
Summary of the invention
The purpose of this utility model is to provide a kind of MQT to combine extension bar, and this combination extension bar is completely embedded each other, realizes bilayer by the securing member of screw thread and outer layer and connects, the stability of connection is effectively ensured.
The technical scheme in the invention for solving the technical problem is: MQT combines extension bar, including combination box cupling body and extension bar body, described combination box cupling body is internal hollow cylinder body, the two ends of described combination box cupling body are provided with symmetrical milling face, the two ends of described combination box cupling body are internally provided with counterbore, described combination box cupling body is positioned at the inside of counterbore and is provided with female thread, the two ends of described extension bar body are provided with the external screw thread corresponding with the female thread combined on box cupling body, described combination box cupling body two ends are threaded connection with extension bar body, described combination box cupling body and connecting rod junction are provided with securing member, described securing member is connected with combination box cupling body by screw.
As optimization, described extension bar body be internally provided with middle limbers.
As optimization, the two ends of described extension bar body is provided with cone.
As optimization, being periphery outside described securing member, medial surface is corresponding with the lateral surface being provided with milling face on combination box cupling body, and described securing member can horizontally slip on combination box cupling body.
As optimization, the cross section of described extension bar body is regular hexagon.
The beneficial effects of the utility model are: compared with prior art, MQT of the present utility model combines extension bar, the connection between extension bar is realized by internal and external threads, and the position connected is provided with securing member, realize bilayer fixing, guarantee stability, and effectively prevent the abrasion of the connection of screw thread, increase the service life.
