Description

Technical Field

[0001] The utility model relates to the technical field of drill rod joints, in particular to a convenient drill rod connector. Background Art

[0002] When using a drilling rig for drilling operations, due to the deep drilling depth, drill rods are often added. The existing drill rods are connected by threads. To disassemble the drill rods, pliers or mechanical clamps and mechanical rotational power are required. When the torque is large during the construction process, the thread tightness of the drill rod is too high and it is difficult to disassemble. It requires a large power to disassemble, which needs to be improved. Utility Model Content

[0014] 1. The utility model is provided with a male head and a female head, an L-shaped protrusion and a clamping block are provided on the outside of the male head, and a through slot adapted to the L-shaped protrusion is provided on the female head. When in use, the L-shaped protrusion is passed through the through slot, and when the clamping block is aligned with the clamping slot on the side of the through slot, the male head is twisted to insert the clamping block into the clamping slot to complete the connection. When disassembly is required, the male head is twisted in the opposite direction to withdraw the clamping block from the clamping slot, and then the L-shaped protrusion is withdrawn from the through slot. It can be completed without pliers or mechanical clamps, and is easy to disassemble and assemble.

[0015] 2. There are outward-protruding side grooves on both sides of the through groove, and the L-shaped protrusion and the card block are both provided with flanges that cooperate with the side grooves, that is, the through groove is a dovetail groove, and the L-shaped protrusion and the side edges of the card block form a dovetail tenon. The side of the card slot is provided with side grooves that cooperate with the flanges of the card block, so that the fit between the male and female heads is tighter.

DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 4 When the drill rod is in use, at least one end of the drill rod is equipped with a male head 1 or a female head 2. When the two drill rods need to be connected, the L-shaped protrusion 4 of the male head is aligned with the through slot 7 and inserted. When the block 5 is aligned with the slot 8, the drill rod is twisted to drive the male head 1 to rotate and the block 5 is stuck in the slot 8 to complete the drill rod connection. When it needs to be withdrawn, the drill rod is twisted in the opposite direction to withdraw the block 5 from the slot 8. When the L-shaped protrusion 4 is completely withdrawn from the through slot 7, the drill rod can be disassembled. The drill rod can be disassembled quickly and conveniently without pliers or mechanical clamps.

[0023] When the clamping block 5 is in the shape of a square, the clamping block 5 is in the shape of a square, and the clamping block 5 is in the shape of a square.

[0024] Specifically, a guide head 11 is provided at the front end of the connecting column 3, and a guide hole 12 is provided in the connecting hole 6 to cooperate with the guide head 11. When the guide head 11 is fully inserted into the guide hole 12, the card block 5 is just aligned with the card slot 8, making the connection between the male head 1 and the female head 2 more convenient.

[0025] Specifically, the male head 1 is provided with a first through hole 13 along the axial direction, and the female head 2 is provided with a second through hole (not shown in the figure) adapted to the first through hole 13 along the axial direction. The mud and water outside the drill rod can flow into the pipe through the first through hole 13 and the second through hole, thereby reducing the soil and water pressure of the drill rod.
