Description

Technical Field

[0001] This utility model belongs to the field of reaming drill bits, specifically a reaming drill bit that is easy to replace. Background Technology

[0002] A reamer is a drill bit specifically designed to enlarge existing holes. It is widely used in furniture manufacturing, especially in the processing of wood and wood composite materials. A reamer can efficiently and accurately enlarge existing holes, ensuring that the size and surface finish of the hole meet the requirements. In furniture manufacturing, reamers can be used to enlarge existing holes or cut new holes to meet specific design requirements or decorative needs.

[0003] In furniture manufacturing, it is often necessary to drill holes in wooden boards to install hardware accessories. When a piece of furniture needs to have multiple holes of different diameters enlarged, it is necessary to frequently change the reamer. The reamer is usually installed by threading, which requires the use of tools such as wrenches. This consumes a lot of time due to the need to change the drill bit. In addition, the threaded installation method means that the reamer can only rotate in one direction. When rotating in the opposite direction, the reamer is prone to falling off, which may damage the furniture and cause unnecessary losses.

[0004] In summary, this utility model provides an easily replaceable reaming drill bit to solve the above-mentioned problems. Utility Model Content

The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model. Example 1

[0021] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides an easily replaceable reaming drill bit, including a reamer body 1. The front of the reamer body 1 is fixedly connected to an installation port 2. A drill bit body 3 is provided on the front of the installation port 2. The rear end of the drill bit body 3 extends into the inner cavity of the installation port 2 and is detachably connected to the inner cavity of the installation port 2. Receiving grooves 4 are provided on both sides of the drill bit body 3. A locking block 5 is movably connected to the inner cavity of the receiving groove 4. A locking groove 6 is provided on both sides of the installation port 2. The two locking blocks 5 extend to the inner cavity of the locking groove 6 on the side that is far apart from each other and engage with the inner cavity of the locking groove 6. A disassembly mechanism 7 is provided on the surface of the installation port 2.

[0022] like Figure 1-4 As shown, after the locking block 5 is pushed into the receiving groove 4, the drill bit body 3 can be inserted into the mounting port 2. When the locking block 5 engages with the inner cavity of the slot 6, the drill bit body 3 can be fixed inside the mounting port 2. Since the mounting port 2 and the drill bit body 3 are connected by a locking mechanism, the drill bit body 3 will not fall off regardless of whether it rotates forward or backward, thus preventing damage to the furniture. The disassembly mechanism 7 can remove the slot 6 from its interior for quick disassembly and replacement, reducing the time consumed and improving the processing efficiency of the furniture. Example 2

[0023] Reference Figure 2 and 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0024] In this embodiment, the disassembly mechanism 7 includes a fixing block 701, which is located on both sides of the reamer body 1 and is fixedly connected to the reamer body 1. A push block 702 is slidably connected to the inner cavity of the fixing block 701. A push post 703 is fixedly connected to the side of the two push blocks 702 that are close to each other. One end of the push post 703 extends into the inner cavity of the receiving groove 4 and is movably connected to the inner cavity of the receiving groove 4.

[0025] A first spring 704 is fitted on the surface of the push column 703. One end of the first spring 704 is fixedly connected to the push block 702, and the other end of the first spring 704 is fixedly connected to the inner wall of the fixing block 701.

[0026] The front and back sides of the inner cavity of the fixing block 701 are provided with limiting grooves 705, and the front and back sides of the push block 702 are fixedly connected with limiting blocks 706. There are four limiting grooves 705 and four limiting blocks 706. One side of the limiting block 706 extends into the inner cavity of the limiting groove 705 and slides with the inner cavity of the limiting groove 705.

[0027] like Figure 2 and 4 As shown, the push block 702 is used to support and protect the internal components. By pressing the push block 702, the push column 703 can be moved. After the push column 703 moves into the inner cavity of the slot 6, it can squeeze the block 5 out of the slot 6 so that the drill body 3 can be disassembled and replaced. At the same time, the first spring 704 will deform due to pressure. The reset force of the first spring 704 is used to reset the push block 702 and the push column 703. When the limiting block 706 slides inside the limiting groove 705, it can limit the push block 702 to prevent the angle of the push block 702 from deflecting. Example 3

[0028] Reference Figure 1 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0029] In this embodiment, a second spring 8 is fixedly connected to the side of the two card blocks 5 that are close to each other, and the end of the second spring 8 away from the card block 5 is fixedly connected to the inner wall of the receiving groove 4.

[0030] The surface of the reamer body 1 is covered with an anti-slip pad 9, and the back of the reamer body 1 is movably connected to a hanging ring 10 via a bearing.

[0031] like Figure 1 As shown, the second spring 8 is used to reset the locking block 5. By taking the anti-slip pad 9, the friction between the hand and the reamer body 1 can be increased, thereby preventing the hand from slipping. By setting the hanging ring 10, the reamer body 1 can be suspended and stored, thereby saving space.

[0032] When in use, activating the reamer body 1 drives the drill bit body 3 to rotate, enabling the drill bit body 3 to enlarge holes in furniture. To install the drill bit body 3, first press the locking block 5 inwards, moving it into the inner cavity of the receiving groove 4. At this time, the second spring 8 will deform under pressure. Then, insert the drill bit body 3 into the mounting opening 2. When the locking block 5 moves to the slot 6, the pressure on the locking block 5 disappears. Under the restoring force of the second spring 8, the locking block 5 can enter the slot 6 and engage with it, thus installing the drill bit body 3. To disassemble and replace the drill bit body 3, first press the push block 702 inwards. Pressing the push block 702 moves the push column 703. After the push column 703 moves into the inner cavity of the slot 6, it can squeeze the locking block 5 out of the slot 6. At this time, the drill bit body 3 can be removed from the mounting opening 2. After removal, replace it with a drill bit body 3 of the required diameter.
