Description

Technical Field

[0001] This utility model relates to an oral diagnostic instrument, specifically to an instrument structure for tooth enamel removal. Background Technology

[0002] In the field of oral healthcare, enamel removal is a crucial step in orthodontic and restorative treatments, aiming to adjust tooth shape and interproximal spaces by removing a small amount of enamel from the tooth surface.

[0003] This device typically includes a gripping rod and a grinding disc. The grinding disc is made of different materials and is a consumable part. Therefore, in practical applications, specific types of grinding discs are replaced or disassembled as needed. In existing technology, the grinding disc is usually fixed to the end of the gripping rod by a snap-fit ​​or insertion method. This fixing method cannot form a firm fit and is prone to detachment or displacement, which causes problems with precision control in actual operation.

[0004] Therefore, the fixing of the abrasive blade to the end of the rod needs to be reinforced, and the disassembly after fixing should be easy to operate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, thereby providing a polishing and glazing removal instrument structure that enhances the fixing of the abrasive plate and allows for easy disassembly.

[0006] To achieve the above objectives, this utility model provides an oral polishing and enamel removal instrument, including a grip, fasteners, and a polishing and enamel removal blade assembly;

[0007] The grip bar has a fixing part, and the fixing part has a through hole;

[0008] A fastener is disposed on one side of the fixing part. The fastener has a threaded engagement part, a clamping plate, and a rotating clamping cylinder. The rotating clamping cylinder is threadedly engaged with the threaded engagement part. The clamping plate is located at the end of the threaded engagement part. The rotating clamping cylinder presses down on the clamping plate when tightening. The through hole passes through the middle of the threaded engagement part and the clamping plate.

[0009] The polishing and glaze removal knife set has a frame, a fixing rod, and an abrasive blade. The abrasive blade is fixed to one side of the frame, and the fixing rod is provided on the other side of the frame. The fixing rod is detachably installed in the through hole.

[0010] Preferably, the clamping plates are arranged circumferentially.

[0011] Preferably, the clamping plate is inclined outward from the side closest to the threaded mating part;

[0012] The outer inner wall of the rotating clamping cylinder forms an inclined wall surface, which is used to contact the clamping plate for pressing.

[0013] Preferably, the outer wall of the rotary clamping cylinder has multiple sets of axially arranged actuating plates, which are used to receive external forces to achieve rotational movement.

[0014] Preferably, the fixing rod has a positioning protrusion, and the inner wall of the fixing part has a positioning recess, and the positioning protrusion and the positioning recess cooperate to position the part.

[0015] Preferably, the positioning protrusion is an elastic protrusion.

[0016] Preferably, the positioning protrusion is a hemispherical structure.

[0017] Preferably, the three sets of hemispherical structures are evenly arranged on the circumferential surface of the fixed rod.

[0018] Preferably, the positioning recess is a multi-level structure, that is, there are multiple sets of positioning recesses in the axial direction of the inner wall of the fixing part, so as to achieve a fixed fit for the fixing rod at different depths.

[0019] Preferably, the grip bar has a curved raised wall in the middle.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. The fasteners ensure a firm fit between the abrasive disc and the gripping rod. When the rotating clamping cylinder overlaps with the threaded part, the contact between the inclined wall and the clamping disc gradually increases, thereby increasing the clamping force.

[0022] 2. The positioning protrusions and recesses make the frosted sheet fit more tightly with the grip bar and facilitate quick engagement by the user, thus achieving better position determination.

[0023] 3. The combination of fasteners, positioning protrusions, and positioning recesses increases the firmness of the abrasive sheet while making it easy to disassemble and operate, thus increasing work efficiency. Attached Figure Description

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] like Figures 1 to 5 As shown, this utility model provides an oral polishing and enamel removal instrument, including a gripping rod 10, a fastener 20, and a polishing and enamel removal blade assembly 30;

[0037] The grip rod 10 has a fixing part 11, and the fixing part 11 has a through hole 12;

[0038] Fastener 20 is disposed on one side of the fixing part 11. Fastener 20 has a threaded engagement part 21, a clamping plate 22 and a rotating clamping cylinder 23. The rotating clamping cylinder 23 is threadedly engaged with the threaded engagement part 21. The clamping plate 22 is located at the end of the threaded engagement part 21. When the rotating clamping cylinder 23 is tightened, it presses down on the clamping plate 22. The through hole 12 passes through the middle of the threaded engagement part 21 and the clamping plate 22.

[0039] The polishing and glaze removal knife assembly 30 has a frame portion 31, a fixing rod 32, and an abrasive disc 33. The abrasive disc 33 is fixed to one side of the frame portion 31, and the fixing rod 32 is provided on the other side of the frame portion 31. The fixing rod 32 is detachably disposed in the through hole 12.

[0040] In practical applications, the fixing rod 32 of the polishing and glaze removal knife assembly 30 is inserted into the through hole 12. After reaching the appropriate position, the clamping cylinder 23 is rotated to tighten it, so as to engage with the threaded part 21. During the tightening process of the clamping cylinder 23, the clamping plate 22 is gradually pressed inward to form a clamping and fixing operation on the fixing rod 32 in the middle. This securely achieves quick locking of the polishing and glaze removal knife assembly 30 and prevents displacement. Moreover, the disassembly process is very convenient. It is only necessary to manually rotate the clamping cylinder 23 in the opposite direction to separate it from the threaded part 21.

[0041] Preferably, the clamping plates 22 are arranged in a circumferential manner, with multiple plates arranged in the circumferential direction to achieve clamping and fixing operation of the fixing rod 32 in the middle position.

[0042] Preferably, such as Figure 3 As shown, the clamping plate 22 is gradually inclined outward from the side close to the threaded mating part 21, that is, it gradually tightens towards the middle, which makes it easier to clamp and fix the fixing rod 32 in the middle.

[0043] The outer inner wall of the rotary clamping cylinder 23 forms an inclined wall surface 231, which is used to contact the clamping plate 22 for pressing. When the rotary clamping cylinder 23 overlaps with the threaded mating part 21, the degree of contact between the inclined wall surface 231 and the clamping plate 22 gradually increases, thereby increasing the clamping force.

[0044] Preferably, the outer wall of the rotary pressing cylinder 23 has multiple sets of axially arranged actuating plates 24, which are used to receive external forces to achieve rotational movement.

[0045] Preferably, such as Figure 4 , Figure 6As shown, the fixing rod 32 has a positioning protrusion 321, and the inner wall of the fixing part 11 has a positioning recess 111. The positioning protrusion 321 and the positioning recess 111 cooperate for positioning. This structure makes the fit tighter and facilitates quick and easy installation for users, thus better determining the position. Each time the device is installed and fixed, the fixing rod 32 is moved within the through hole 12 until the positioning protrusion 321 is exactly engaged with the positioning recess 111, producing a "click" sound. This indicates that the two have achieved positioning and engagement, and the device is in the correct position. Then, the rotating clamping cylinder 23 and the clamping plate 22 can be fixed.

[0046] Preferably, the positioning protrusion 321 is an elastic protrusion. The elastic protrusion helps the fixing rod 32 move more smoothly within the through hole 12.

[0047] Preferably, the positioning protrusion 321 is a hemispherical structure.

[0048] Preferably, the three sets of hemispherical structures are evenly arranged on the circumferential surface of the fixed rod 32.

[0049] Preferably, the positioning recess 111 has a multi-level structure, that is, multiple sets of positioning recesses 111 are provided in the axial direction of the inner wall of the fixing part 11 to achieve fixed fit for the fixing rod 32 at different depths.

[0050] Preferably, the grip bar 10 has a curved raised wall in the middle to facilitate gripping.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
