[0002] Drill bit protection structure refers to a structure that can effectively protect the drill bit, preventing it from being damaged by collisions, wear, or other factors during transportation, storage, or short-distance transfer of the drill bit to work scenarios.

[0003] The prior art discloses a high-strength protective structure for drill bits, with application number CN202420384095.0, which relates to the field of drill bit protection technology. This utility model, through the cooperation between the protective sleeve, connecting seat, drill bit, bidirectional lead screw, clamping block, arc-shaped clamping groove, rotating plate and lever, allows the protective sleeve to be directly inserted into the surface of the drill bit, and then the clamping block clamps and fixes the drill bit, thereby protecting the drill bit. It eliminates the need to disassemble the drill bit for storage and protection when the electric drill is moved short distances. The operation is simple, convenient and practical. The cooperation between the through hole, the first bearing, the second bearing and the storage groove allows the rotating plate to be rotated to drive the bidirectional lead screw to rotate, making the operation even simpler and more convenient.

[0004] There are many specifications of drill bits in current production, with lengths ranging from a few centimeters to tens of centimeters, but the protective sleeve of the above-mentioned protective structure has a fixed length and cannot be adapted to drill bits of different lengths.

[0016] (1) In this utility model, the protective sleeve is composed of an inner cylinder, an outer cylinder and a fixing ring. During the protective operation, the fixing ring is fixed to the drill bit body. Then, by adjusting the position of the inner cylinder on the outer cylinder, the length of the protective sleeve can be adjusted. At the same time, the handle is rotated to make the protrusion fit tightly with the inner cylinder to fix the length of the protective sleeve.

[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a high-strength protective structure for drill bits is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a high-strength protective structure for a drill bit according to an embodiment of the present utility model includes a protective sleeve 1. The protective sleeve 1 is composed of an inner cylinder 2, an outer cylinder 3, and a fixing ring 12. The inner cylinder 2 is sleeved with the outer cylinder 3. A fixing ring 12 is provided on the upper part of the outer cylinder 3. The fixing ring 12 is installed on the surface of the drill bit body 15. A through hole 7 is provided on the side surface of the outer cylinder 3, and a hinge seat 6 is provided at the through hole 7. The hinge seat 6 is connected to a handle 8 through a rotating shaft. A protrusion 9 is provided on the side surface of the handle 8, and the protrusion 9 is made of rubber. The protrusion 9 is fitted with the inner cylinder 2.

[0027] In one embodiment, during protective operation, the retaining ring 12 is fixed to the drill bit body 15. Then, by adjusting the position of the inner cylinder 2 on the outer cylinder 3, the length of the protective sleeve 1 can be adjusted. At the same time, the handle 8 is rotated to make the protrusion 9 fit tightly against the inner cylinder 2, thus fixing the length of the protective sleeve 1. Then, it is put on the outside of the drill bit body 15 and connected to the retaining ring 12, so that it can fit tightly to drill bit bodies 15 of various lengths. This ensures that drill bit bodies 15 of different specifications can be fully protected, eliminating the need to frequently replace the entire protective structure for drill bit bodies 15 of different lengths. This improves the versatility and efficiency of the protective structure and reduces costs.

[0028] Specifically, magnetic rings 10 are provided on the inner side of the outer cylinder 3 and the surface of the fixing ring 12, and a first filling ring 11 is provided on the outer side of the magnetic ring 10.

[0029] In one embodiment, when performing protective operations, the magnetic ring 10 inside the outer cylinder 3 and the magnetic ring 10 at the fixing ring 12 magnetically attract each other, thereby enabling the quick installation and disassembly of the protective sleeve 1 and the drill bit body 15, improving work efficiency. The setting of the first filling ring 11 can increase the friction between the protective sleeve 1 and the fixing ring 12, which is beneficial to improving their connection tightness.

[0030] Specifically, a second filling ring 13 is provided inside the fixing ring 12.

[0031] In one embodiment, it is used to fill the space between the retaining ring 12 and the drill bit body 15, making the connection between the retaining ring 12 and the drill bit body 15 tighter and preventing the retaining ring 12 from falling off the drill bit body 15.

[0032] Specifically, the outer cylinder 3, the inner cylinder 2, and the fixing ring 12 are all made of aluminum alloy.

[0033] In one embodiment, aluminum alloy has advantages such as light weight, high strength, and corrosion resistance, which can reduce the overall weight while ensuring the strength of the protective structure, making it easier for operators to use.

[0034] Specifically, both the outer cylinder 3 and the inner cylinder 2 are provided with a silicone buffer layer 4, and the inner side of the silicone buffer layer 4 is provided with a protective pad 5.

[0035] In one embodiment, the silicone buffer layer 4 and the protective pad 5 can further protect the drill bit and effectively absorb the vibration and impact generated during the transfer of the drill bit.

[0036] Specifically, the outer surface of the outer cylinder 3 is provided with anti-slip strips 14 in a ring array.

[0037] In one embodiment, it helps operators increase friction when holding the protective sleeve 1, preventing the hand from slipping and improving the safety and convenience of operation.

[0038] Working principle: During protective operation, the fixing ring 12 is fixed to the drill bit body 15. Then, by adjusting the position of the inner cylinder 2 on the outer cylinder 3, the length of the protective sleeve 1 can be adjusted. At the same time, rotating the handle 8 causes the protrusion 9 to fit tightly with the inner cylinder 2, fixing the length of the protective sleeve 1. Then, it is put on the outside of the drill bit body 15 and connected to the fixing ring 12, so that it can fit tightly to drill bit bodies 15 of various lengths, ensuring that drill bit bodies 15 of different specifications can be fully protected. There is no need to frequently replace the entire protective structure for drill bit bodies 15 of different lengths, improving the versatility and efficiency of the protective structure and reducing costs. When performing protective operation, the magnetic ring 10 inside the outer cylinder 3 and the magnetic ring 10 at the fixing ring 12 attract each other, thereby realizing the quick installation and removal of the protective sleeve 1 and the drill bit body 15, improving work efficiency. The setting of the first filling ring 11 can increase the friction between the protective sleeve 1 and the fixing ring 12, which is conducive to improving the tightness of the connection.
