Description
Technical Field
[0001] The utility model relates to the technical field of sharpening equipment, in particular to a sharpening device for a handheld periodontal subgingival scraper. Background Art
[0002] The periodontal subgingival scaler is a professional tool used by dentists to treat periodontal disease, especially for deep cleaning of periodontal pockets. There are usually many types and models of periodontal subgingival scalers to meet the needs of different tooth positions, periodontal pocket depths and root shapes, but the original shape of the working end of different models of scalers is the same.
[0003] As shown in the attached figure Figure 1 As shown, the existing scraper includes a hand-held rod 04 and working ends 05 located at both ends of the hand-held rod 04, as shown in the accompanying drawings. Figure 2 As shown, the working end 05 is set to an arc shape, such as Figure 3 As shown, from the cross-sectional view of the working end 05, the top of the working end 05 is a first arcuate surface 01 that is concave downward, the bottom of the working end 05 is a second arcuate surface that is convex downward, and the ridge where the first arcuate surface 01 intersects the second arcuate surface is the blade surface 03. When in use, the blade surface 03 is brought into contact with the tooth surface to clean the teeth.
[0004] The blade of the scaler should be kept sharp during operation, so the blade that becomes blunt after wear needs to be sharpened regularly. Currently, there are two types of tools for sharpening scalers: electric and manual. However, the basic principle is the same. They both sharpen the side of the second curved surface close to the blade surface in a straight line. This method not only destroys the original curved shape of the second curved surface, but also only sharpens the side of the blade close to the second curved surface, while not sharpening the side of the blade close to the first curved surface, making the blade surface not sharp enough after sharpening, and the sharpening effect is poor.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] like Figure 1 and Figure 2 As shown, the present invention provides a sharpener for a handheld periodontal subgingival scaler, which mainly sharpens both sides of the blade surface 03 by moving the grindstone 32 to improve the sharpening effect.
[0030] The sharpener for a handheld periodontal subgingival scaler comprises a base plate 10, a fixing structure 20 for fixing a handheld rod 04 is provided on one side of the top of the base plate 10, and a sharpening structure 30 for sharpening a working end 05 is provided on the other side of the top of the base plate 10;
[0031] The sharpening structure 30 includes a vertical plate 31, a grinding stone 32 is provided on the side of the vertical plate 31 close to the fixed structure 20, a first slide groove 33 penetrating the vertical plate 31 is provided on the side of the vertical plate 31 close to the grinding stone 32, and the first slide groove 33 is consistent with the extension direction of the working end 05, and both are set to be arc-shaped, a first slider 34 is provided inside the first slide groove 33, and the first slider 34 is fixedly connected to the grinding stone 32, so that the first slider 34 slides along the first slide groove 33, thereby driving the grinding stone 32 to move along the path of the first slide groove 33;
[0032] A groove 35 is formed on the grindstone 32 away from the vertical plate 31. The top of the inner wall of the groove 35 is a downwardly convex first grinding surface 36, and the bottom of the inner wall of the groove 35 is a downwardly concave second grinding surface 37. The first grinding surface 36 matches the first curved surface 01 near the blade surface 03, and the second grinding surface 37 matches the second curved surface 02 near the blade surface 03, so as to sharpen both sides of the blade surface 03 respectively.
[0033] At present, the tools for sharpening the scaler are all linearly sharpened on the side of the second curved surface 02 close to the blade surface 03. This method not only destroys the original curved shape of the second curved surface 02, but also only sharpens the side of the blade surface 03 close to the second curved surface 02, while not sharpening the side of the blade surface 03 close to the first curved surface 01. As a result, the blade surface 03 is not sharp enough after sharpening, and the sharpening effect is poor. Therefore, it is necessary to develop a sharpening tool that does not destroy the original shape of the working end 05 and has a better sharpening effect.
[0034] This embodiment enables the grindstone 32 to move along the arc extension direction of the working end 05 to sharpen the first arc surface 01 and the second arc surface 02 on both sides of the blade surface 03 respectively. The original shapes of the first arc surface 01 and the second arc surface 02 can be maintained, and both sides of the blade surface 03 can be sharpened at the same time. Compared with the existing method of sharpening only one side, the blade surface 03 after sharpening is sharper, thereby improving the sharpening effect.
[0035] In actual use, 1. fix the scraper hand-held rod 04 on the fixed structure 20 so that the scraper hand-held rod 04 is placed vertically, and place the scraper working end 05 in the groove 35 of the grindstone 32;
[0036] 2. Adjust the height of the handle 04 so that the first grinding surface 36 fits closely with the first curved surface 01 near the blade surface 03;
[0037] 3. Pushing the first slider 34 back and forth makes the first slider 34 move back and forth inside the first slide groove 33, so that the first grinding surface 36 on the grindstone 32 moves along the first arc surface 01 on the working end 05 of the scraper, thereby sharpening the first arc surface 01;
[0038] 4. Adjust the height of the handle 04 so that the second grinding surface 37 fits the second curved surface 02 close to the blade surface 03;
[0039] 5. By pushing the first slider 34 back and forth, the first slider 34 moves back and forth inside the first slide groove 33, so that the second grinding surface 37 on the grindstone 32 moves along the second arcuate surface 02 on the working end 05 of the scraper, thereby sharpening the second arcuate surface 02.
[0040] As a preferred embodiment of the present embodiment, the fixing structure 20 is described in detail below. The fixing structure 20 includes a column 21 and a clamping structure 40 disposed on one side of the column 21. The clamping structure 40 is connected to the column 21 for sliding up and down, so as to adjust the height of the working end 05. The working end 05 is raised so that the first curved surface 01 close to the blade surface 03 is in contact with the first grinding surface 36, and the working end 05 is lowered so that the second curved surface 02 close to the blade surface 03 is in contact with the second grinding surface 37. The scaler is fixed by the clamping structure 40, and then the height of the scaler is adjusted by moving the clamping structure 40 up and down.
[0041] The clamping structure 40 is further described below. Figure 6As shown, the clamping structure 40 includes a moving block 41 and a fixing ring 42 fixedly connected to one side of the moving block 41, a first threaded rod 43 is threadedly connected inside the fixing ring 42, and a clamping block 44 is fixedly connected to one end of the first threaded rod 43 close to the fixing ring 42, and the clamping block 44 is arranged inside the fixing ring 42, so that the first threaded rod 43 is rotated to adjust the distance between the clamping block 44 and the inner wall of the fixing ring 42. The hand-held rod 04 is passed through the fixing ring 42, and then the first threaded rod 43 is tightened to fix the hand-held rod 04.
[0042] The column 21 is provided with a second slide groove 22 on one side close to the moving block 41, and a second slider 23 is fixedly connected to one side of the moving block 41. The second slider 23 is connected to slide up and down inside the second slide groove 22, and a second threaded rod 24 is rotatably connected to the top of the second slider 23. The second threaded rod 24 is threadedly connected to the column 21, and the moving block 41 is adjusted to move up and down by rotating the second threaded rod 24. By rotating the second threaded rod 24, the second threaded rod 24 moves up and down, thereby driving the second slider 23 to move up and down inside the second slide groove 22, thereby adjusting the height of the scraper so that the grinding stone 32 matches the working end 05.
