Description

Technical Field

[0001] The utility model relates to the technical field of diamond drill construction, in particular to an anti-seepage diamond drill bit device. Background Art

[0002] In building construction, it is often necessary to open through holes in the wall to facilitate the laying of corresponding pipelines and other facilities.

[0003] After retrieval, a Chinese patent with the publication number CN214392487U discloses a construction drill bit, which includes a drill bit body, a mounting plate, a sleeve, a first dust-proof ring, and a second dust-proof ring; one end of the drill bit body penetrates through the mounting plate and is fixedly connected to the mounting plate; the sleeve is sleeved outside the mounting plate, a groove is provided inside the sleeve, the inner wall of the groove abuts against the mounting plate, the sleeve is movably connected to the mounting plate, the drill bit body penetrates through the sleeve, and a part of the drill bit body is received in the groove; a part of the first dust-proof ring is received in the groove and is fixedly connected to the sleeve, and the second dust-proof ring is received in the groove and is fixedly connected to the mounting plate.

[0004] Based on the above retrieval and in combination with the prior art, it is found that:

[0005] After the above drill bit finishes drilling, the drilled hole is relatively single. Since there is a gap between the pipeline and the hole, a small amount of seepage water flows to the wall through the gap, which will pollute the wall after a period of time, not only affecting the beauty of the wall, but even causing leakage and other phenomena, so there are certain limitations. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides an anti-seepage diamond drill bit device, which realizes the setting of double holes by setting two misaligned drill bits. By installing a drain pipe on the outer hole, even if there is still a gap between the pipeline and the hole, the seepage water can be drained to the outside of the wall through the drain pipe, thereby ensuring that the wall will not be polluted.

[0007] The technical solution for achieving the purpose of the utility model is: an anti-seepage diamond drill bit device, including a first drill bit, a plurality of first saw teeth are fixedly installed at equal intervals at the bottom of the first drill bit, a connecting piece is fixedly installed at the top of the first drill bit, a second drill bit is arranged in the middle of the first drill bit, and a plurality of second saw teeth are fixedly installed at equal intervals at the bottom of the second drill bit.

[0008] In some embodiments, a plurality of hollow strips are arranged at equal intervals on the outer peripheral wall of the second drill bit.

[0009] In some embodiments, a plurality of chutes are arranged at equal intervals in the middle of the first drill bit, and a plurality of threaded holes are arranged at equal intervals inside the chutes.

[0010] In some embodiments, an adjusting ring is fixedly installed at the end of the second drill bit. A plurality of sliders are fixedly installed equidistantly inside the adjusting ring, and the sliders are slidably engaged with the sliding grooves.

[0011] In some embodiments, a fastening bolt is threadedly connected to the adjusting ring and the slider, and the end of the fastening bolt is threadedly connected inside the threaded hole.

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

[0013] Firstly: The first drill bit and the second drill bit provided by this utility model can perform double drilling on the wall. The second drill bit is spaced a certain distance from the first drill bit and the diameter of the second drill bit is larger than that of the first drill bit. Therefore, after the first drill bit drills through, the second drill bit does not drill through. At this time, by installing a drain pipe in the hole drilled by the second drill bit, the seepage water generated at the gap can be drained, thereby preventing pollution to the wall and improving the aesthetics of the wall. In addition, by using the provided hollow strips, the range of the gap between the first drill bit and the second drill bit can be covered, which is convenient for cleaning the debris at any position and improving the stability of the device for drilling holes.

[0014] Secondly: By setting an adjusting ring, the second drill bit can be adjusted through the sliders on the adjusting ring and the sliding grooves on the second drill bit, and can be continuously adjusted according to the thickness of the wall. After adjusting to the appropriate position, the second drill bit is fixed with the fastening bolt cooperating with the threaded hole on the sliding groove, which is convenient for drilling operations and improves the practicability of the device.

[0015] It solves the problem that after the above-mentioned drill bit finishes drilling, the drilled hole is relatively single. Since there is a gap between the pipeline and the hole, a small amount of seepage water flows to the wall through the gap, which will cause pollution to the wall after a period of time, not only affecting the aesthetics of the wall, but even causing leakage and other phenomena.
