Description

Technical Field

[0001] The utility model belongs to the technical field of artificial teeth manufacturing, and particularly relates to an artificial teeth undercut marking device. Background Art

[0002] Dentures are artificial teeth that are placed after teeth fall out or are extracted to restore chewing, aesthetics, pronunciation and other functions. During oral rehabilitation treatment, when designing dentures for patients, it is necessary to determine the position of the denture undercut and mark it. Traditionally, doctors hold dentures to complete the marking process, which is inefficient. However, with the development of technology, some denture marking devices have emerged that can clamp dentures and adjust them at multiple angles, effectively improving the marking efficiency.

[0003] For example, patent application No. CN201822206362.2 discloses a denture undercut marking device, which aims to solve the problem that since there is no clamping device on the marking table to fix the denture model on the marking table, when the marking table is tilted, the denture model placed thereon is prone to position displacement or even falling, resulting in difficulty in marking the undercut area of ​​the denture, thereby reducing the denture quality and work efficiency. The device comprises a base, a bracket and a marking table, and is characterized in that: the marking table is mounted on the base, and a magnet is installed at the bottom of the marking table, an iron disc matching the magnet is installed at the top of the bottom, and a locking device is installed at the top of the marking table. The clamping device installed on the marking table of the utility model can clamp the denture model on the marking table to prevent it from shifting while marking the undercut area of ​​the denture, thereby improving the denture quality and work efficiency.

[0004] In the prior art, by setting a universal ball and a tightening bolt, the marking table can not only clamp and fix the denture but also complete the adjustment at multiple angles to complete the marking process. However, there are still many shortcomings: First, although the universal ball in the prior art can realize the adjustment conversion at multiple angles, it is easy to shake and slip during use, and it is easy to rotate without force due to excessive pressure, resulting in the denture being unable to complete the marking process smoothly, affecting the marking quality; secondly, the surface of the denture is complex and the limit column in the prior art can realize three-point clamping, but the existence of the special-shaped surface cannot fully guarantee the complete contact of the clamping points, which can easily lead to unstable clamping and cannot guarantee stable clamping and fixation. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a denture undercut marking device. The utility model uses a rubber arc cover and an anti-slip strip to cooperate with the upper arrangement of an arc panel, so that the ball head rod can ensure good stability when rotating, effectively avoiding the occurrence of random shaking or slipping and loss of force, ensuring the accuracy of the marking, and can effectively clamp and fix the denture in cooperation with the clamping component, so that the denture can complete efficient marking processing.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a denture undercut marking device comprises a base 10 and an operating frame 11. The operating frame 11 is arranged in the base 10, a ball head seat 16 is arranged at the bottom of the operating frame 11, a ball head rod 23 with a spherical bottom is rotatably arranged in the ball head seat 16, an anti-skid component is arranged outside the ball head rod 23 in the ball head seat 16, a connecting disk 24 is connected to the end surface of the ball head rod 23, a clamping disk 15 is rotatably arranged on the connecting disk 24, a clamping component is arranged on the end surface of the clamping disk 15, and a marking pen 22 is arranged on one side of the clamping disk 15 on the operating frame 11;

[0036] The anti-skid component includes a rubber arc cover 27 arranged on the inner circular surface of the ball head seat 16 outside the spherical surface of the ball head rod 23, and a plurality of arc panels 28 for clamping the ball head rod 23 are slidably arranged inside the rubber arc cover 27. A plurality of anti-skid strips 31 in contact with the outer circular surface of the ball head rod 23 are arranged on the inner circular surface of the rubber arc cover 27 outside the arc panel 28.

[0037] The bottom end face of the ball head rod 23 is spherical and rotatably fits in the ball head seat 16, so that the connecting disk 24 can rotate in multiple directions, and the rotating surface is effectively increased. The anti-slip component can prevent the ball head rod 23 from being out of force during rotation, ensuring that the ball head rod 23 has a certain stability and will not shake at will, thereby ensuring the accuracy of the denture marking; the clamping component on the clamping disk 15 can clamp the denture, so that the staff can mark various positions of the denture with the marking pen 22, and the clamping disk 15 is rotatably set on the connecting disk 24, so that the connecting disk 24 itself can rotate in various directions. The clamping disk 15 can also rotate based on the connecting disk 24, so that the staff can complete the marking process in multiple directions when completing the denture clamping at a single time, thereby reducing the number of clamping times.

[0038] The rubber arc cover 27 and the anti-skid strip 31 are both made of anti-skid rubber material, which can perform anti-skid and stable treatment on the outer cylindrical surface of the ball head rod 23 to prevent the ball head rod 23 from shaking at will. The arc panel 28 can clamp the ball head rod 23, and the arc panel 28 can adjust the clamping force so that the ball head rod 23 can complete the rotation under a certain pressure, thereby avoiding the occurrence of force loss during manual rotation.

[0039] Further, such as Figure 4 , Figure 5 and Figure 6 As shown, the anti-skid assembly also includes a push cylinder 29 arranged in the ball head seat 16 on one side of each arc panel 28, and a push rod 30 is slidably arranged in the push cylinder 29. One end of the push rod 30 extends out of the end surface of the push cylinder 29 and is connected to the arc panel 28.

[0040] The push cylinder 29 and the push rod 30 can push and retract the arc panel 28 and adjust the clamping force.

[0041] Further, such as Figure 5 and Figure 6 As shown, the anti-skid assembly also includes an arc elastic sheet 32 ​​that is evenly arranged on the inner circumferential surface of the rubber arc cover 27 and is bent downward along the circumferential direction.

[0042] Only one end of the downward curved elastic sheet 32 ​​is connected to the inner surface of the rubber arc cover 27. When the ball head rod 23 loses force or rotates abnormally, it will generate vibration during the contact process with the ball head rod 23, thereby eliminating the rotation force and reducing the rotation speed of the ball head rod 23 to force it to stop.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, the clamping assembly includes three polygonal columns 25 arranged on the clamping plate 15, each polygonal column 25 is sleeved with a clamping tube 17, and a plurality of anti-slip groove surfaces 33 are arranged on the end surface of the polygonal column 25 that contacts the clamping tube 17.

[0044] The polygonal column 25 is provided with at least six planes, so that the clamping tube 17 can be stably sleeved on the outside of the polygonal column 25, and the multiple anti-slip groove surfaces 33 on the clamping tube 17 can effectively improve the stability effect.

[0045] Further, such as Figure 7 and Figure 8 As shown, the clamping assembly also includes a driving frame 19 arranged below one of the polygonal columns 25 and within the end surface of the clamping disk 15. A screw rod 20 with one end extending out of the outer cylindrical surface of the clamping disk 15 is rotatably arranged within the driving frame 19, and a transmission block 39 connected to the bottom of the polygonal column 25 is arranged on the screw rod 20 for transmission.

[0046] The two polygonal columns 25 and the clamping cylinder 17 are fixed, and one of the polygonal columns 25 will move toward the two fixed polygonal columns 25 under the action of the screw rod 20 and the transmission block 39, thereby performing a three-point clamping process on the denture surface.

[0047] Further, such as Figure 8 As shown, the clamping assembly also includes a plurality of annular grooves 34 uniformly arranged on the outer circumferential surface of the clamping tube 17 along a straight line direction, each annular groove 34 is provided with an arc convex plate 35, and a spherical particle 36 is provided at the bottom of the annular groove 34 on one side of the arc convex plate 35.

[0048] The curved convex plate 35 and the clamping tube 17 are both made of elastic rubber material, which can prevent the surface of the denture from being damaged when clamping the denture. Multiple curved convex plates 35 that protrude outward but have a certain deformation ability can better fit on the various special-shaped surfaces of the denture, thereby improving the clamping and fixing effect of the denture. In the above relationship, the curved convex plate 35 will bend and deform inward under greater pressure, and the inward-bent curved convex plate 35 will contact the spherical particles 36, so that the spherical particles 36 can contact the surface of the denture through the curved convex plate 35, thereby providing multiple point fixation treatments.

[0049] like Fig. 9 and Fig.10 As shown, a rotating ring groove 37 is provided on the end surface of the connecting disk 24 below the clamping disk 15, a rotating slider 40 is slidably provided in the rotating ring groove 37, the top of the rotating slider 40 is connected to the clamping disk 15, and an anti-slip ring 38 is provided outside the rotating slider 40 in the rotating ring groove 37.

[0050] The clamping plate 15 rotates in the rotating ring groove 37 through the rotating slider 40. The anti-skid ring 38 in the rotating slider 40 is made of anti-skid rubber, which can increase the rotational friction between the rotating slider 40 and the rotating ring groove 37, thereby preventing the clamping plate 15 from rotating at will.

[0051] like Figure 1 and Figure 2As shown, a slide bar 12 is provided at one side of the operation frame 11, and a connecting arm 13 which can be adjusted at multiple angles is slidably provided on the slide bar 12, and a pen holder 14 for placing a marking pen 22 is connected to one end of the connecting arm 13.

[0052] The connecting arm 13 has multiple degrees of freedom arms, which is a prior art and will not be elaborated in detail herein. The pen holder 14 is used to place the marking pen 22 .

[0053] like Figure 1 As shown, a control panel 21 is provided on one end surface of the base 10 .

[0054] The staff can adjust the operation of each moving part inside the device according to the control panel 21.

[0055] In this embodiment: when the denture is concave and needs to be marked at various positions, the staff will place the denture against the outer circumferential surfaces of the two fixed clamping cylinders 17, and then rotate the screw 20. The screw 20 will drive the transmission block 39 and the polygonal column 25 on the transmission block 39 to move toward the surface of the denture, thereby driving the clamping cylinder 17 on the polygonal column 25 and the multiple curved convex plates 35 on the outer circumferential surface of the clamping cylinder 17 to move toward the denture, thereby clamping and fixing the denture. During the clamping process, the multiple curved convex plates 35 will deform under pressure and fit onto the surface of the denture, thereby better clamping the special-shaped surface of the denture and ensuring that the denture will not move during marking.

[0056] When the denture is fixed, the staff can send a pressure parameter instruction to the push cylinder 29 through the control panel 21, so that the push cylinder 29 pushes the push rod 30 and the arc panel 28 to move, so that the clamping force of the arc panel 28 on the outer cylindrical surface of the ball head rod 23 can be adjusted to a comfortable force when the human body rotates the ball head rod 23.

[0057] The staff can then swing the connecting plate 24 and the ball head rod 23 in all directions, front, back, left, and right, so that all positions of the denture can be displayed outwards. The staff can then swing the connecting arm 13 so that the marking pen 22 can mark various places on the surface of the denture. During this process, the anti-slip strip 31 in the rubber arc cover 27 and the arc elastic sheet 32 ​​can ensure that the ball head rod 23 will not shake at will.

[0058] During the swinging of the ball head rod 23, the staff can also rotate the clamping plate 15 so that the rotating slider 40 at the bottom of the clamping plate 15 rotates in the rotating ring groove 37 and contacts the anti-slip ring 38, thereby stably completing the rotation adjustment process and allowing the staff to better complete the marking process.

[0059] Embodiment 2:

[0060] like Figure 1As shown, a denture undercut marking device, the clamping assembly also includes a plurality of elastic bands 18 connected between two fixed clamping cylinders 17.

[0061] As a further embodiment, when the denture is too small to abut against the outer circumferential surfaces of the two fixed clamping tubes 17, the staff can put two clamping tubes 17 connected with multiple elastic bands 18 on the outside of the polygonal column 25, so that during the clamping process, the multiple elastic bands 18 can limit and fix one end of the denture. The elastic band 18 is made of elastic metal wire, has a certain deformation ability and a certain hardness, and can effectively clamp and fix the denture.

[0062] Embodiment three:

[0063] like Fig.10 As shown, a denture undercut marking device is provided, wherein a scale surface 26 is provided on the end surface of the connecting disk 24 , and a plurality of indicating arrows 41 are provided on the scale surface 26 on the outer circumferential surface of the clamping disk 15 .

[0064] As a further embodiment, the scale surface 26 is engraved according to a standard angle. When the clamping disk 15 is rotated to adjust the angle, the staff can judge the rotation angle of the clamping disk 15 by the relationship between the indicating arrow 41 and the scale surface 26, so that the parameters can be better recorded and the marking effect is improved.
