Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis model polishing technology, specifically a dental prosthesis model polishing device. Background Technology

[0002] Dental model is a core concept in prosthodontics. It refers to the basic mold or replica used to make dentures. It is usually an accurate, negative or positive replica of the relevant area in the patient's mouth (the edentulous area and adjacent tissues).

[0003] The process of making a denture model includes: taking an impression, where the dentist uses impression material and a tray to take a negative model of the edentulous area and surrounding tissues in the patient's mouth; pouring the model, where the technician pours the mixed model material (usually dental plaster or artificial stone) into the impression, and after the model material has completely solidified and hardened, carefully separates the impression from the solidified model; finishing and polishing, removing excess material, and finishing the base and edges of the model according to standard requirements to make it flat, aesthetically pleasing, and easy to install and operate on an articulator;

[0004] When polishing denture models, technicians usually use handheld dental polishing machines / miniature motors with various shapes of tungsten carbide burs and diamond burs to finely refine the edges and tooth details. This process generates a lot of debris and dust. Therefore, a dust collection device is used to collect the dust generated during the actual polishing operation. At the same time, to prevent high-speed flying debris from impacting the technicians, a transparent baffle is placed between the polishing area and the technicians. The transparent baffle intercepts the flying debris while maintaining a good observation angle.

[0005] However, the existing transparent baffle has a fixed tilt angle, and the angle between the transparent baffle and the viewer of technicians of different heights is different. An unsuitable tilt angle will affect the clarity, accuracy and comfort of the view. In addition, the fixed transparent baffle is not convenient for storing the device and cleaning the surface of the transparent baffle facing the grinding area. Based on this, a denture model grinding device is provided. Utility Model Content

[0006] The purpose of this invention is to provide a device for grinding denture models in order to solve the problems mentioned above.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dental prosthesis model grinding device, comprising a collection component for collecting dust and debris generated during grinding, wherein the collection component comprises a trapezoidal box, a grid plate, a suction pipe, and a rotating groove;

[0008] The grid plate is fixed to the top of the trapezoidal box, the suction pipe is fixed to one side of the trapezoidal box and communicates with the inner cavity of the trapezoidal box, and the suction pipe is connected to an external suction device through a hose. The suction force generated by the external suction device is transmitted to the grid opening of the grid plate through the suction pipe and the inner cavity of the trapezoidal box to realize the suction and collection of dust and debris.

[0009] The rotating slot is located at the top front end of the trapezoidal box. A protective component is installed on the trapezoidal box through the rotating slot. The protective component is used to intercept flying debris.

[0010] As a further embodiment of this utility model: the protective component includes a transparent baffle, a connecting seat, a rotating shaft, and a locking nut;

[0011] The bottom end of the transparent baffle is inserted into the inner side of the connector and is fixedly bonded to the connector with glue.

[0012] The rotating shaft is symmetrically fixed on both sides of the connecting seat. The connecting seat is distributed inside the rotating groove and is rotatably connected to the trapezoidal box through the rotating shaft. The rotating shaft is used to provide rotational support for the angular rotation of the transparent baffle.

[0013] One of the rotating shafts protrudes to the outside of the trapezoidal box and is formed with external threads. The locking nut is threaded to the outside of the rotating shaft and fits tightly against the side of the trapezoidal box to fix the tilt angle of the transparent baffle.

[0014] Transparent baffles at different angles are used to match the line of sight of technicians of different heights.

[0015] As a further improvement of this utility model: the rotating groove is connected to the upper surface of the grid plate, and the rotatable angle of the transparent baffle is greater than 180 degrees.

[0016] As a further embodiment of this utility model: the bottom of the inner wall of the rotating groove is formed with an arc-shaped groove, and a C-shaped rubber sleeve is bonded and fixed to the outer side of the connecting seat, with the outer wall of the C-shaped rubber sleeve tightly fitting the inner wall of the arc-shaped groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By incorporating a protective component with an angle-adjustable function, the transparent baffle can be tilted to accommodate the viewing angle of technicians of different heights.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 In this embodiment of the present invention, a dental model grinding device includes a collection component 1 for collecting dust and debris generated during grinding. The collection component 1 includes a trapezoidal box 101, a grid plate 102, a suction pipe 103, and a rotating groove 104.

[0027] The grid plate 102 is fixed to the top of the trapezoidal box 101, and the suction pipe 103 is fixed to one side of the trapezoidal box 101 and communicates with the inner cavity of the trapezoidal box 101. The suction pipe 103 is connected to an external suction device through a hose. The suction force generated by the external suction device is transmitted to the grid opening of the grid plate 102 through the suction pipe 103 and the inner cavity of the trapezoidal box 101 to realize the suction and collection of dust and debris.

[0028] A rotating slot 104 is formed at the top front end of the trapezoidal box 101. A protective component 2 is installed on the trapezoidal box 101 through the rotating slot 104. The protective component 2 is used to intercept flying debris.

[0029] Protective component 2 includes a transparent baffle 201, a connecting seat 202, a rotating shaft 203, and a locking nut 204;

[0030] The bottom end of the transparent baffle 201 is inserted into the inner side of the connector 202 and is fixedly bonded to the connector 202 with glue.

[0031] The rotating shaft 203 is symmetrically fixed on both sides of the connecting seat 202. The connecting seat 202 is distributed inside the rotating groove 104 and is rotatably connected to the trapezoidal box 101 through the rotating shaft 203. The rotating shaft 203 is used to provide rotational support for the angular rotation of the transparent baffle 201.

[0032] A rotating shaft 203 protrudes to the outside of the trapezoidal box 101 and is formed with external threads. A locking nut 204 is threaded to the outside of the rotating shaft 203 and fits tightly against the side of the trapezoidal box 101 to fix the tilt angle of the transparent baffle 201.

[0033] Transparent baffles 201 at different angles are used to match the line of sight of technicians of different heights;

[0034] The rotating groove 104 is connected to the upper surface of the grid plate 102, and the transparent baffle 201 has a rotation angle greater than 180 degrees.

[0035] In this embodiment, it should be noted that when the device is not in daily use, the transparent baffle 201 is folded and attached to the upper surface of the grille plate 102 (e.g., Figure 4 It can be easily stored and transported. At the same time, the transparent baffle 201 can also be flipped away from the trapezoidal box 101, so that the surface of the transparent baffle 201 near the polishing area faces upward, which facilitates the cleaning operation of this surface.

[0036] The following is how to use this device when grinding denture models:

[0037] Place the entire device on the workbench. The suction tube 103 is connected to the external suction equipment through the hose. Then, loosen the locking nut 204 to release it from the tight compression state with the outer wall of the trapezoidal box 101. At this time, the transparent baffle 201 can be manually flipped upward to the tilted state.

[0038] During this process, the tilt angle of the transparent baffle 201 can be determined according to the line of sight of the polishing technician: the line of sight of the polishing technician should be as close as possible to the perpendicular state of the surface of the transparent baffle 201. After determining the angle of the transparent baffle 201, tighten the locking nut 204 so that the locking nut 204 fits tightly against the outer wall of the trapezoidal box 101.

[0039] When the technician is polishing the denture model with a handheld polishing machine, the polishing area is located above the trapezoidal box 101, and the transparent baffle is located between the polishing area and the technician. At this time, the external suction device is activated. The external suction device generates suction to draw the dust and debris generated by polishing into the trapezoidal box 101, and finally it is drawn into the external suction device for filtration and collection.

[0040] Meanwhile, during the polishing process, the debris that flies towards the technicians will be intercepted by the transparent baffle 201, providing good protection.

[0041] Please refer to this carefully. Figures 1-5 The bottom of the inner wall of the rotating groove 104 is formed with an arc groove 105, and a C-shaped rubber sleeve 205 is bonded and fixed to the outside of the connecting seat 202. The outer wall of the C-shaped rubber sleeve 205 is tightly fitted with the inner wall of the arc groove 105.

[0042] In this embodiment: the friction between the C-shaped rubber sleeve 205 and the inner wall of the rotating groove 104 can provide an initial limit for the tilt angle of the transparent baffle 201. When the locking nut 204 is loosened, the transparent baffle 201 can remain stable and rotate without being pushed by an external force. When the transparent baffle 201 is pushed manually, the friction between the C-shaped rubber sleeve 205 and the inner wall of the rotating groove 104 can be overcome, so as to realize the convenient angle adjustment of the transparent baffle 201.

[0043] In addition, when the transparent baffle 201 is adjusted to any angle, the C-shaped rubber sleeve 205 and the rotating groove 104 remain in contact, providing a seal between the connecting seat 202 and the rotating groove 104, thereby achieving a good protective effect.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
