Abstract
The invention discloses a kind of linking diamond thin-wall drill bits, including rotation connection cylinder, connecting cylinder and sanding block, rotating block is provided at the top of the rotation connection cylinder, the bottom of the rotation connection cylinder offers the first thread groove, the first threaded block compatible with the first thread groove is provided at the top of the connecting cylinder, the bottom of the connecting cylinder inner wall offers the second thread groove.The present invention can increase the length of linking diamond thin-wall drill bit to a certain extent, sanding block can be connected to the inside of connecting cylinder after connecting cylinder damage to continue to use, spare sanding block can be taken out after sanding block and diamond bit damage be connected to inside connecting cylinder continuing to use；And the part of damage can be abandoned when the damage of linking diamond thin-wall drill bit, and be unlikely to cause to waste by linking diamond thin-wall drill bit whole discarding.
Description
Technical field
The present invention relates to diamond tool technical field, specially a kind of linking diamond thin-wall drill bit.
Background technique
Diamond thin-wall drill bit is also known as rhinestone head, hollow boring bit, is mainly used in building, water, electricity, warm, coal gas, sky
Adjust, Pipe installing when beat porthole, the drilling of the foundation engineerings such as highway, airfield runway, bridge, tunnel, jacking, coring,
Stone material, ceramics etc. are nonmetallic to answer fragile material to punch.
Diamond Bobbi drill bit using when mostly be that the work such as drill is carried out using it, but common diamond core drill bit
Head length is inadequate, and drill bit easily damages since it is desired that carrying out intensive work, and the diamond cutter tooth meeting after damage
Abandoning perhaps depot repair with sanding block, directly discarding or maintenance will cause great waste in this way, and can pole
Big delays the duration, for this purpose, it is proposed that a kind of linking diamond thin-wall drill bit.
Summary of the invention
The purpose of the present invention is to provide a kind of linking diamond thin-wall drill bits, are asked with solve to propose in background technique
Topic.
To achieve the above object, the invention provides the following technical scheme: a kind of linking diamond thin-wall drill bit, including turn
Connecting cylinder, connecting cylinder and sanding block are moved, rotating block, the bottom of the rotation connection cylinder are provided at the top of the rotation connection cylinder
The first thread groove is offered, the first threaded block compatible with the first thread groove, the company are provided at the top of the connecting cylinder
The bottom of connect cylinder inner wall offers the second thread groove, and compatible with the second thread groove second is provided at the top of the sanding block
The bottom of threaded block, the sanding block inner wall is welded with diamond cutter tooth.
Preferably, first thread groove is identical as the size of the second thread groove, first threaded block and the second screw thread
The size of block is identical, and second threaded block can be installed on the inside of rotation connection cylinder by the first thread groove.
Preferably, the linking diamond thin-wall drill bit using when need to rotate the first threaded block and the first thread groove
Engagement is connected with each other to make to be rotatablely connected cylinder and connecting cylinder, then the second threaded block is engaged with the rotation of the second thread groove thus
It is connected with each other sanding block and connecting cylinder.
Preferably, the manufacture material of the rotation connection cylinder, connecting cylinder, the first threaded block, sanding block and the second threaded block
It is rigid material.
Preferably, the diamond cutter tooth is welded on the inner wall of sanding block by high-frequency welding manner.
Compared with prior art, the invention has the following advantages:
1, the present invention can increase the length of linking diamond thin-wall drill bit to a certain extent；
2, the inside that sanding block can be connected to connecting cylinder after connecting cylinder damages continues to use；
3, spare sanding block can be taken out after sanding block and diamond bit damage and is connected to inside connecting cylinder continue
It uses；
4, the part of damage can be abandoned when linking diamond thin-wall drill bit damages, and be unlikely to linking Buddha's warrior attendant
Stone thin drilling bit all abandons and causes to waste.
Detailed description of the invention
Fig. 1 is front view structural representation of the present invention；
Fig. 2 is rotating block main view schematic diagram of the present invention；
Fig. 3 is connecting cylinder main view schematic diagram of the present invention.
In figure: 1 rotation connection cylinder, 2 rotating blocks, 3 first thread grooves, 4 connecting cylinders, 5 first threaded blocks, 6 second thread grooves,
7 sanding blocks, 8 second threaded blocks, 9 diamond cutters tooth.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of linking diamond thin-wall drill bit, including rotation
Connecting cylinder 1, connecting cylinder 4 and sanding block 7, the top of the rotation connection cylinder 1 are provided with rotating block 2, the rotation connection cylinder 1
Bottom offers the first thread groove 3, and the top of the connecting cylinder 4 is provided with first threaded block compatible with the first thread groove 3
5, the bottom of 4 inner wall of connecting cylinder offers the second thread groove 6, and the top of the sanding block 7 is provided with and the second thread groove 6
Compatible second threaded block 8, first thread groove 3 is identical as the size of the second thread groove 6,5 He of the first threaded block
The size of second threaded block 8 is identical, and second threaded block 8 can be installed on the interior of rotation connection cylinder 1 by the first thread groove 3
Portion, the linking diamond thin-wall drill bit using when need engage the rotation of the first threaded block 5 and the first thread groove 3 to make
It is rotatablely connected cylinder 1 and connecting cylinder 4 is connected with each other, then engage to make to polish with the rotation of the second thread groove 6 by the second threaded block 8
Block 7 and connecting cylinder 4 are connected with each other, and the bottom of 7 inner wall of sanding block is welded with diamond cutter tooth 9, and the diamond cutter tooth 9 is logical
