Technical Field

[0001] This application relates to the field of dental prosthesis manufacturing technology, and in particular to a trimming device for dental prosthesis processing. Background Technology

[0002] With the continuous progress of society, economy, and technology, dental equipment is increasingly incorporating modern scientific technologies, and its functions, appearance, safety, and hygiene are constantly being developed and improved. Simplicity, ease of operation, and high efficiency are the main trends in the development of dental equipment. After aligning teeth on the wax rim, the wax rim with the dentures needs to be trimmed to the shape of the natural gum line.

[0003] A search revealed that Chinese Patent CN211049664U discloses a denture trimming knife, which has the function of storing and protecting the blade. However, after each use, the blade needs to be removed from the handle and put back into the storage box, and then reinstalled before each use. This repeated disassembly and reinstallation is inconvenient. Therefore, a denture trimming device is proposed to solve the above problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-4 This utility model provides a technical solution for a trimming device for denture processing:

[0024] A denture processing trimming device includes a handle 1, a storage part 2 fixedly connected to the top of the handle 1, a receiving cavity 3 formed inside the storage part 2, a connector 4 slidably connected to the inner wall of the receiving cavity 3, a trimming blade 5 detachably connected to the connector 4, an upper port 6 for the trimming blade 5 to extend from the top of the storage part 2, and the connector 4 moving downward can drive the trimming blade 5 to be stored inside the receiving cavity 3.

[0025] Specifically, the moving connector 4 drives the trimming blade 5 to be completely submerged into the receiving cavity 3, and the receiving groove protects and stores the trimming blade 5. Compared with the existing technology, this trimming device does not require disassembly and installation of the trimming blade 5 each time it is used, making it convenient and quick to use. The user holds the handle 1 and uses the trimming blade 5 to trim the denture.

[0026] The handle 1 is hollow, and the inner wall of the handle 1 is slidably connected to the slide rod 7. The top of the slide rod 7 is fixedly connected to the bottom of the connector 4. The movement of the slide rod 7 drives the connector 4 to move, which in turn drives the trimming knife 5 to move.

[0027] The surface of the handle 1 is provided with a groove, and a slider 8 is slidably connected to the inner wall of the groove. The slider 8 is connected to the slide rod 7 to drive the slide rod 7 to move. By setting the slider 8, it is convenient for the user to move the slide rod 7 using the slider 8.

[0028] The inner wall of the handle 1 is provided with a locking groove 9, and the surface of the slide rod 7 is provided with a groove 10. The inner wall of the groove 10 is slidably connected with a locking block 11 that matches the locking groove 9. A spring 12 is fixedly connected to the end of the locking block 11, and the other end of the spring 12 is fixedly connected to the inner wall of the groove 10. By setting the spring 12 to have an outward pushing force on the locking block 11, the locking block 11 is stably placed in the locking groove 9 to position the slide rod 7, thereby improving the stability of the trimming device.

[0029] A limiting groove 13 is provided on the surface of the slide bar 7. The slider 8 is slidably connected to the limiting groove 13. A transmission component connected to two locking blocks 11 is provided in the limiting groove 13. When the slider 8 squeezes the transmission component, it can drive the locking block 11 to move out of the locking groove 9. By setting the limiting groove 13, the slide bar 7 can move along the limiting groove 13 to act on the transmission component, so that the transmission component drives the locking block 11 to move out of the locking groove 9.

[0030] The transmission component is a pull rope 14. The two ends of the pull rope 14 pass through the inner walls of the two grooves 10 and are fixedly connected to the two locking blocks 11. The top of the slider 8 is provided with anti-slip texture. By setting the pull rope 14, when it is subjected to the pressure of the slider 8, the pull rope 14 deforms and its two ends drive the two locking blocks 11 to move out of the locking groove 9.

[0031] The connector 4 is a cylindrical object with threads on the inner wall and an open top. The bottom of the trimmer 5 is fixedly connected to a threaded block 15 with a surface that mates with the connector 4. The threaded block 15 is threadedly connected to the connector 4. The top of the storage part 2 is provided with a limiting ring 16. The upper port 6 is formed in the middle of the limiting ring 16. The diameter of the upper port 6 is not less than the diameter of the threaded block 15. By setting the threaded block 15 to mate with the connector 4, it is convenient to disassemble and replace the trimmer 5.

[0032] Working principle: When using this denture processing trimming device, the user first presses down on the slider 8, which squeezes the pull rope 14, causing the pull rope 14 to bend. The two ends of the pull rope 14 then move the two locking blocks 11 out of the locking groove 9. Then, the user moves the slider 8 upward, causing the slide rod 7 to move upward. The slide rod 7 moves the connecting piece 4, which in turn moves the trimming blade 5 upward and extends it. The user holds the handle 1 and uses the trimming blade 5 to trim the denture. After trimming, the user presses down on the slider 8 again, squeezing the pull rope 14. This causes the two ends of the pull rope 14 to move the two locking blocks 11 out of the locking groove 9. The user then moves the slider 8 downward, causing the slide rod 7 to move downward. The slide rod 7 moves the connecting piece 4, which in turn moves the trimming blade 5 downward and completely submerges it in the receiving groove. The receiving groove protects and stores the trimming blade 5. Compared to existing technologies, this trimming device eliminates the need for disassembling and reassembling the trimming blade 5 each time it is used, making it convenient and quick to use.
