Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically a fixing base suitable for 3D printing of dentures. Background Technology

[0002] In the field of modern dental prosthodontics, 3D printing technology for dentures has been widely used due to its advantages such as high precision and personalized customization. During the 3D printing process, the mounting base, as a key component supporting and securing the denture model, directly affects the quality and precision of the printed denture.

[0003] In existing technologies, denture models often have complex shapes and overhanging parts, such as denture models containing multiple crowns and those exhibiting complex gingival morphology. During 3D printing, if the base cannot provide sufficient support points or suitable support angles for these overhanging parts, the denture model is prone to positional shifts or local deformations during the printing process, resulting in the final printed denture failing to meet the precision requirements for clinical use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a fixed base suitable for 3D printing of dentures, solving the problem that existing bases cannot provide sufficient support points or suitable support angles.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a fixed base suitable for 3D printing of dentures, including a base, and further including: a fixed frame fixedly connected to the inner side of the base, a support component fixedly connected to the inner side of the fixed frame, a connecting component fixedly connected to the top of the support component, the connecting component being used to fix the denture model on the top of the support component, and by adjusting the height of the support component on the fixed frame, the position of each connecting component is adapted to the bottom of the denture model;

[0008] The support assembly includes a fixed block, an internally threaded swivel ring rotatably connected to the inner side of the fixed block, a hollow threaded rod threadedly connected to the inner side of the internally threaded swivel ring, and a limit rod slidably connected to the inner side of the hollow threaded rod. The limit rod restricts the rotation of the hollow threaded rod, ensuring that the hollow threaded rod can only move in the vertical direction.

[0009] The connecting assembly includes a connecting seat, a spherical block is slidably connected to the inner side of the connecting seat, a threaded post is fixedly connected to the top of the spherical block, and the bottom of the denture model is threadedly connected to the threaded post.

[0010] Preferably, the support components are arranged in a ring along the central axis of the fixing frame, the outer side of the fixing block is fixedly connected to the inner wall of the fixing frame, the inner side of the fixing frame is fixedly connected to the top of the limiting rod, the top of the internal threaded swivel is fixedly connected to a knob, and the top of the hollow threaded rod is fixedly connected to the bottom of the connecting component. Rotating the knob causes the internal threaded swivel to rotate inside the fixing block.

[0011] Preferably, a compression spring is fixedly connected to the inner side of the connecting seat, a slider is fixedly connected to the top of the compression spring, and a limit rod is fixedly connected to the top of the slider. When the limit rod is dislodged from the slot, the compression spring is compressed, and the spherical block can slide inside the connecting seat.

[0012] Preferably, the bottom of the connecting seat is fixedly connected to the top of the hollow threaded rod, and the inner wall of the slider is slidably connected to the outer wall of the connecting seat. Sliding the slider downwards can cause the slider to drive the limiting rod to move downwards and disengage from the slot.

[0013] Preferably, the inner wall of the connecting seat is slidably connected to the outer wall of the limiting rod, and the top end of the limiting rod is inserted into the outer side of the spherical block through a slot, and the slot is opened in the wall of the spherical block. When the top end of the limiting rod is inserted into the corresponding slot, the spherical block can be fixed in the connecting seat.

[0014] (III) Beneficial Effects

[0015] This invention provides a fixing base suitable for 3D printing of dentures. It has the following beneficial effects:

[0016] (i) The base is equipped with a support component. By rotating the knob, the internal threaded ring rotates inside the fixed block. At this time, the hollow threaded rod moves up and down along its axial direction under the restriction of the limiting rod. The limiting rod restricts the rotation of the hollow threaded rod, ensuring that the hollow threaded rod can only move in the vertical direction, thereby achieving precise adjustment of the height of the support component to meet the needs of different shapes of denture models.

[0017] (ii) The base is equipped with a connecting component. The slider slides down, causing the slider to move the limiting rod downward and disengage it from the slot. At this time, the compression spring is compressed, and the spherical block can slide inside the connecting seat. When the denture model is installed in place, the slider is released. At this time, under the elastic force of the compression spring, the slider drives the limiting rod to reset, so that the top of the limiting rod is reinserted into the corresponding slot, thereby fixing the spherical block in the connecting seat and thus fixing the denture model to accommodate different installation angles of the denture model.

[0023] 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.

[0024] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a fixed base for 3D printing of dentures, including a base 1, and further including: a fixing frame 2 fixedly connected to the inner side of the base 1, a support component 3 fixedly connected to the inner side of the fixing frame 2, and a connecting component 4 fixedly connected to the top of the support component 3, the connecting component 4 being used to fix the denture model to the top of the support component 3; the base 1 is placed and fixed on the printing platform, and then the height of the support component 3 on the fixing frame 2 is adjusted so that the position of each connecting component 4 is adapted to the bottom of the denture model.

[0025] The support assembly 3 includes a fixing block 31, with an internally threaded swivel ring 32 rotatably connected to the inner side of the fixing block 31. A hollow threaded rod 33 is threadedly connected to the inner side of the internally threaded swivel ring 32, and a limit rod 34 is slidably connected to the inner side of the hollow threaded rod 33. The support assembly 3 is arranged in a ring along the central axis of the fixing frame 2. The outer side of the fixing block 31 is fixedly connected to the inner wall of the fixing frame 2, and the inner side of the fixing frame 2 is fixedly connected to the top of the limit rod 34. A knob 35 is fixedly connected to the top of the internally threaded swivel ring 32, and the top end of the hollow threaded rod 33 is fixedly connected to the bottom of the connecting assembly 4. When fixing the denture model, the knob 35 can be rotated. The rotation of the knob 35 causes the internally threaded swivel ring 32 to rotate inside the fixing block 31. At this time, the hollow threaded rod 33 will move up and down along its axial direction under the restriction of the limit rod 34. The limiting rod 34 restricts the rotation of the hollow threaded rod 33, ensuring that the hollow threaded rod 33 can only move in the vertical direction, thereby achieving precise adjustment of the height of the support component 3 to adapt to the different shapes of the denture model.

[0026] The connecting assembly 4 includes a connecting seat 41, a spherical block 45 slidably connected to the inner side of the connecting seat 41, a threaded post 46 fixedly connected to the top of the spherical block 45, a compression spring 42 fixedly connected to the inner side of the connecting seat 41, a slider 43 fixedly connected to the top of the compression spring 42, a limiting rod 44 fixedly connected to the top of the slider 43, the bottom of the connecting seat 41 fixedly connected to the top of the hollow threaded rod 33, the inner wall of the slider 43 slidably connected to the outer wall of the connecting seat 41, the inner wall of the connecting seat 41 slidably connected to the outer wall of the limiting rod 44, the top of the limiting rod 44 being inserted into the outer side of the spherical block 45 through a slot 47, and the slot 47 being opened in the wall of the spherical block 45, and the bottom of the denture model being threadedly connected to the threaded post 46. During installation, slide the slider 43 downwards, causing the slider 43 to move the limiting rod 44 downwards and disengage it from the slot 47. At this time, the compression spring 42 is compressed, and the spherical block 45 can slide inside the connecting seat 41. After the denture model is installed in place, release the slider 43. At this time, under the elastic force of the compression spring 42, the slider 43 drives the limiting rod 44 to reset, so that the top of the limiting rod 44 is reinserted into the corresponding slot 47, thereby fixing the spherical block 45 in the connecting seat 41, and thus fixing the denture model to accommodate different installation angles of the denture model.

[0027] In use, the base 1 is placed on the printing platform and fixed. Then, by adjusting the height of the support component 3 on the fixing frame 2, the position of each connecting component 4 is adapted to the bottom of the denture model.

[0028] When fixing the denture model, the knob 35 can be rotated. The rotation of the knob 35 causes the internal threaded ring 32 to rotate inside the fixing block 31. At this time, the hollow threaded rod 33 will move up and down along its axial direction under the restriction of the limiting rod 34. The limiting rod 34 restricts the rotation of the hollow threaded rod 33, ensuring that the hollow threaded rod 33 can only move in the vertical direction, thereby achieving precise adjustment of the height of the support component 3 to adapt to the different shapes of the denture model.

[0029] When the denture model needs to be installed, the bottom of the denture model is threadedly connected to the threaded post 46. During installation, slide the slider 43 downwards, causing the slider 43 to move the limiting rod 44 downwards and disengage it from the slot 47. At this time, the compression spring 42 is compressed, and the spherical block 45 can slide inside the connecting seat 41. After the denture model is installed in place, release the slider 43. At this time, under the elastic force of the compression spring 42, the slider 43 drives the limiting rod 44 to reset, so that the top of the limiting rod 44 is reinserted into the corresponding slot 47, thereby fixing the spherical block 45 in the connecting seat 41, and thus fixing the denture model to accommodate different installation angles of the denture model.
