[0004] In order to solve the above technical problems, the utility model discloses a multi-faceted pyramid quick-connect grooved drill rod, comprising: a rod body; a male joint is provided at one end of the rod body, and a female joint is provided at the other end; the outer surface of the rod body is provided with a plurality of spiral chip grooves in an annular array, edges are formed between the chip grooves, the diameter of the female joint is larger than the diameter of the rod body, the chip grooves extend to the female joint, and raised drilling teeth are formed on the surface of the female joint; an annular clamping groove is provided at the bottom of the inner thread groove of the female joint, and a positioning groove is provided on the bottom surface, and a sealing ring is limited to the annular clamping groove and the positioning groove.

[0005] Furthermore, the drilling teeth are inclined along the axial direction of the rod body.

[0006] Furthermore, the female connector is in the shape of a cone.

[0007] Furthermore, the sealing ring is in a ring shape, and a ring-shaped array of protrusions is provided on one side thereof.

[0008] Furthermore, the sealing ring is in a ring shape, and a raised annular portion is provided on one side thereof.

[0009] Compared with the prior art, the present application can obtain the following technical effects:

[0010] The utility model provides a circle of drilling teeth on the outside of the female joint, which can expand and correct the drill hole and further break up the slag to prevent the drill hole from being blocked and excessive wear on the drill rod surface; an annular clamping groove and a positioning groove are provided inside the female joint, which can clamp the positioning sealing ring and ensure no leakage when the female joint and the male joint are matched.

[0011] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0018] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a drill rod according to an embodiment of the utility model; Figure 2 It is a cross-sectional schematic diagram of a drill rod according to one embodiment of the utility model.

[0019] A multi-faceted pyramid quick-connect grooved drill rod, comprising: a rod body 1; a male joint 2 is provided at one end of the rod body 1, and a female joint 3 is provided at the other end; a plurality of spiral chip grooves 4 in an annular array are provided on the outer surface of the rod body 1, edges 5 are formed between the chip grooves 4, the diameter of the female joint 3 is larger than the diameter of the rod body 1, the chip grooves 4 extend to the female joint 3, and raised drilling teeth 6 are formed on the surface of the female joint 3; an annular groove 7 is provided at the bottom of the inner thread groove of the female joint 3, a positioning groove 8 is provided on the bottom surface, and a sealing ring 9 is limited to the annular groove 7 and the positioning groove 8.

[0020] The drilling teeth 6 are inclined along the axial direction of the rod body 1, and the female joint 3 is conical; the sealing ring 9 is ring-shaped, and one side thereof is provided with a plurality of protrusions in an annular array, and the number and position of the positioning grooves 8 correspond one to one with the protrusions.

[0021] The sealing ring 9 is in a ring shape, and a raised annular portion is provided on one side thereof. The positioning groove 8 is an annular groove.

[0022] The sealing ring 9 is stuck on the inner side of the female connector 3. When the female connector 3 is matched with the male connector 2, the front end surface of the male connector 2 is pressed against the sealing ring 9. The position setting of the annular groove 7 and the positioning groove 8 can prevent the sealing ring 9 from falling off. The sealing ring 9 is replaced regularly to ensure the sealing between the drill rods.

[0023] In summary, the utility model provides a circle of drilling teeth 6 on the outside of the female connector 3, and the drilling teeth 6 can expand and correct the drill hole, and can also further break up the slag to prevent the drill hole from being blocked and avoid excessive wear on the drill rod surface; an annular groove 7 and a positioning groove 8 are provided inside the female connector 3, which can be clamped with a positioning sealing ring 9, so that there is no leakage when the female connector 3 and the male connector 2 are matched.

[0024] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
