Description

Technical Field

[0001] This utility model relates to the field of drill bit structure technology, and in particular to a drilling drill bit structure. Background Technology

[0002] Geology refers to the properties and characteristics of the Earth, mainly including the Earth's material composition, structure, tectonics, and developmental history. This includes the Earth's strata differentiation, physical properties, chemical properties, rock properties, mineral composition, the occurrence and contact relationships of rock strata and rock masses, the Earth's tectonic development history, biological evolution history, climate change history, and the occurrence and distribution patterns of mineral resources. Drills are needed to drill holes in the Earth's surface when conducting geological research.

[0003] In existing technologies, during rotary drilling, the outer wall of the drill bit continuously contacts and moves relative to the borehole wall, generating friction. As drilling depth and time increase, this friction causes gradual wear on the drill bit's outer wall material. This wear is particularly pronounced in hard rock formations or when the borehole diameter is small and the gap between the drill bit and the borehole wall is narrow. Wear on the outer wall can affect the normal use of the drill bit. However, in traditional drill bits, the outer wall is often integrated with the drill bit itself, resulting in high replacement costs. Utility Model Content

[0004] The purpose of this invention is to solve the problem that wear on the outer wall of the drill bit may affect its normal use, but in traditional drill bits, the outer wall is integrated with the drill bit, resulting in high replacement costs. Therefore, this invention proposes a new drilling bit structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drilling bit structure, comprising a drill bit body, two slots symmetrically formed on the outside of the drill bit body, a storage groove formed on the top surface of the slot, a first threaded hole formed through the inner wall of the storage groove, a first threaded rod threadedly connected inside the first threaded hole, a handle fixedly installed on the top of the first threaded rod, a locking block fixedly installed on the bottom of the first threaded rod, insert plates slidably installed inside both slots, locking grooves formed through the top of the insert plates, a first outer shell and a second outer shell fixedly installed at opposite ends of the two insert plates respectively, control plates fixedly installed at both ends of the first outer shell, control grooves formed at both ends of the second outer shell, and the two control plates slidably connected to the two control grooves respectively.

[0006] Preferably, the bottom of the drill bit body is provided with a top head, the top of the top head is provided with a connecting groove, and the inner side wall of the connecting groove is provided with a fixing groove.

[0007] Preferably, the drill bit body has an operating groove inside, and a second threaded hole is formed through the top surface of the operating groove. A second threaded rod is threadedly connected inside the second threaded hole. A handle is fixedly installed on the top of the second threaded rod, and a pressure plate is movably connected to the bottom of the second threaded rod.

[0008] Preferably, a connecting plate is fixedly installed at the bottom of the drill bit body. A limiting groove is formed on the side of the connecting plate opposite to the drill bit body. A spring is fixedly installed on the inner wall of the limiting groove. A limiting plate is fixedly installed at one end of the spring. A fixing block and a push plate are fixedly installed on the outer wall of the limiting plate. One end of the push plate enters the operating groove, and one end of the fixing block penetrates the connecting plate.

[0009] Preferably, a protective ring is fixedly installed at the bottom of the handle, and a protective groove is provided at the top of the drill bit body.

[0010] Preferably, the outer wall of the pressure plate is in contact with the inner wall of the operating groove.

[0011] Preferably, the outer wall of the insert plate is fitted to the inner wall of the slot, and the outer wall of the card block is fitted to the inner wall of the card slot.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when the first or second outer shell is worn, the operator rotates the handle, which drives the first threaded rod to rotate. The first threaded rod rises along the first threaded hole, thereby driving the locking block to rise. The locking block leaves the slot, and the operator pulls the first or second outer shell, causing the insert plate to leave the slot and the control plate to leave the control slot. Then, the operator replaces the first or second outer shell by inserting the insert plate into the slot. The operator then rotates the handle in the opposite direction, and the locking block enters the slot. This completes the replacement, allowing for the replacement of only the first or second outer shell, thus reducing costs.

[0014] 2. In this utility model, when the top head is damaged, the operator turns the handle, which drives the second threaded rod to rotate, causing the second threaded rod to descend along the second threaded hole. This causes the pressure plate to descend, and the pressure plate contacts the inclined surface of the push plate. The push plate moves, and then, through the limiting plate, it drives the fixing block away from the fixing groove. At this time, the operator can remove the top head and replace it with a new one. The connecting plate is inserted into the connecting groove, and the inclined surface of the fixing block contacts the inner wall of the connecting groove. The fixing block is squeezed into the limiting groove, and the spring is compressed. When the fixing groove moves to the side of the fixing block, the elastic force of the spring pushes the fixing block into the fixing groove, thus completing the replacement and improving the replacement efficiency.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figures 1-4 As shown, this utility model provides a drilling bit structure, including a drill bit body 1. Two slots 5 are symmetrically opened on the outside of the drill bit body 1. A storage groove 6 is opened on the top surface of the slot 5. A first threaded hole 7 is opened through the inner wall of the storage groove 6. A first threaded rod 8 is threadedly connected inside the first threaded hole 7. A handle 9 is fixedly installed on the top of the first threaded rod 8. A locking block 10 is fixedly installed on the bottom of the first threaded rod 8. Insert plates 24 are slidably installed inside the two slots 5. A locking groove 25 is opened through the top of the insert plates 24. A first outer shell 2 and a second outer shell 3 are fixedly installed on opposite ends of the two insert plates 24, respectively. Control plates 27 are fixedly installed on both ends of the first outer shell 2. Control grooves 26 are opened on both ends of the second outer shell 3. The two control plates 27 are slidably connected to the two control grooves 26, respectively.

[0023] The overall effect of Embodiment 1 is that when the first outer shell 2 or the second outer shell 3 is worn, the operator rotates the handle 9, which drives the first threaded rod 8 to rotate. The first threaded rod 8 rises along the first threaded hole 7, thereby driving the locking block 10 to rise. The locking block 10 leaves the locking slot 25. At this time, the operator pulls the first outer shell 2 or the second outer shell 3, the insert plate 24 leaves the slot 5, and the control plate 27 leaves the control slot 26. Then, the operator replaces the first outer shell 2 or the second outer shell 3, inserts the insert plate 24 into the slot 5, and the operator rotates the handle 9 in the opposite direction, so that the locking block 10 enters the locking slot 25. In this way, the replacement can be completed. This allows for the replacement of the first outer shell 2 or the second outer shell 3 individually, reducing costs.

[0024] Example 2, as Figures 1-4 As shown, further, a top head 4 is provided at the bottom of the drill bit body 1, a connecting groove 28 is provided at the top of the top head 4, and a fixing groove 29 is provided on the inner side wall of the connecting groove 28.

[0025] Furthermore, the drill bit body 1 has an operating groove 17 inside, and a second threaded hole 18 is opened through the top surface of the operating groove 17. A second threaded rod 19 is threadedly connected inside the second threaded hole 18. A handle 21 is fixedly installed on the top of the second threaded rod 19, and a pressure plate 20 is movably connected to the bottom of the second threaded rod 19.

[0026] Furthermore, a connecting plate 11 is fixedly installed at the bottom of the drill bit body 1. A limiting groove 12 is opened on the side of the connecting plate 11 opposite to the drill bit body 1. A spring 13 is fixedly installed on the inner wall of the limiting groove 12. A limiting plate 14 is fixedly installed at one end of the spring 13. A fixing block 15 and a push plate 16 are fixedly installed on the outer wall of the limiting plate 14. One end of the push plate 16 enters the operating groove 17, and one end of the fixing block 15 passes through the connecting plate 11.

[0027] Furthermore, a protective ring 23 is fixedly installed at the bottom of the handle 21, and a protective groove 22 is provided on the top of the drill bit body 1 to prevent external dust and dirt from contacting the second threaded rod 19.

[0028] Furthermore, the outer wall of the pressure plate 20 is in contact with the inner wall of the operating groove 17 to prevent the pressure plate 20 from rotating when the second threaded rod 19 rotates.

[0029] Furthermore, the outer wall of the insert plate 24 fits against the inner wall of the slot 5, and the outer wall of the card block 10 fits against the inner wall of the card groove 25. When the card block 10 enters the card groove 25, the insert plate 24 can be fixed.

[0030] The effect achieved by the entire embodiment 2 is as follows: when the top head 4 is damaged, the operator turns the handle 21, which drives the second threaded rod 19 to rotate, causing the second threaded rod 19 to descend along the second threaded hole 18, causing the pressure plate 20 to descend. The pressure plate 20 contacts the inclined surface of the push plate 16, causing the push plate 16 to move. This, in turn, drives the fixing block 15 away from the fixing groove 29 through the limiting plate 14. At this time, the operator can remove the top head 4 and replace it with a new top head 4. The connecting plate 11 is inserted into the connecting groove 28, and the inclined surface of the fixing block 15 contacts the inner wall of the connecting groove 28. The fixing block 15 is squeezed into the limiting groove 12, and the spring 13 is compressed. When the fixing groove 29 moves to the side of the fixing block 15, the elastic force of the spring 13 pushes the fixing block 15 into the fixing groove 29, thus completing the replacement and improving the replacement efficiency.

[0031] Working principle: When the first outer shell 2 or the second outer shell 3 is worn, the operator rotates the handle 9, which drives the first threaded rod 8 to rotate. The first threaded rod 8 rises along the first threaded hole 7, thereby driving the locking block 10 to rise. The locking block 10 leaves the slot 25. At this time, the operator pulls the first outer shell 2 or the second outer shell 3, the insert plate 24 leaves the slot 5, and the control plate 27 leaves the control slot 26. Then, the operator replaces the first outer shell 2 or the second outer shell 3, inserts the insert plate 24 into the slot 5, and rotates the handle 9 in the opposite direction. The locking block 10 enters the slot 25, thus completing the replacement. This allows for the replacement of only the first outer shell 2 or the second outer shell 3, reducing costs. When the top head 4 is damaged, the operator turns the handle 21, which drives the second threaded rod 19 to rotate, causing the second threaded rod 19 to descend along the second threaded hole 18. This causes the pressure plate 20 to descend, and the pressure plate 20 contacts the inclined surface of the push plate 16. The push plate 16 moves, and then, through the limiting plate 14, it drives the fixing block 15 away from the fixing groove 29. At this time, the operator can remove the top head 4 and replace it with a new one. The connecting plate 11 is inserted into the connecting groove 28, and the inclined surface of the fixing block 15 contacts the inner wall of the connecting groove 28. The fixing block 15 is squeezed into the limiting groove 12, and the spring 13 is compressed. When the fixing groove 29 moves to the side of the fixing block 15, the elastic force of the spring 13 pushes the fixing block 15 into the fixing groove 29. This completes the replacement and improves the replacement efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
