Technical Field

[0001] This utility model relates to the field of support skeleton technology for vacuum 3D printing, and in particular to a support skeleton for vacuum 3D printing. Background Technology

[0002] Vacuum 3D printing is an additive manufacturing technology performed in a vacuum environment. It improves material properties, reduces defects, and enhances printing accuracy and finished product quality by placing the printing process in a vacuum or low-pressure environment. This technology is particularly suitable for fields with high requirements for material purity, structural integrity, and microstructure.

[0003] Vacuum 3D printing technology is becoming increasingly mature, and human models can also be made using this technology. However, human models require support and fixation during use to ensure their stability. Existing support and fixation devices for human models simply clamp and fix the limbs for protection. Since each part of the human model is different, conventional support and fixation devices cannot guarantee the absolute stability of the human model. Therefore, the support and fixation devices for human models made by vacuum 3D printing are inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the support and fixing devices for vacuum 3D printed human models cannot be properly fitted and fixed to the human model, and to provide a support skeleton for vacuum 3D printing.

[0006] In a preferred embodiment, the positioning block is slidably connected to the second base, and the positioning block is fixedly connected to the first base. Mounting blocks are fixedly connected to the outer surfaces of both the first base and the second base.

[0007] In a preferred embodiment, the connecting mechanism includes a pull rod, which is sleeved inside the base and slidably connected to the base. One end of the pull rod is provided with a limiting piece, which is fixedly connected to the pull rod.

[0008] In a preferred embodiment, a spring is sleeved on the outer surface of the pull rod, and the two ends of the spring are respectively fixedly connected to the outer surface of the limiting plate and the inner wall of the base.

[0019] 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. Example

[0020] like Figures 1-5 As shown, this utility model provides a technical solution: a support frame for vacuum 3D printing, comprising: a 3D model 1, a fixing mechanism 2 on the outer side of the 3D model 1, the fixing mechanism 2 including an insert block 21, an insert block 22 on one side of the insert block 21, both insert blocks 21 and 22 being fitted inside the 3D model 1, both insert blocks 21 and 22 being slidably connected to the 3D model 1, a fixing block 23 on one side of the insert block 21, a fixing block 24 on one side of the fixing block 23, both fixing blocks 23 and 24 being fitted inside the 3D model 1, and fixing blocks 21, 22, 23, 24 ... Both 3 and fixed block 24 are slidably connected to 3D model 1. One end of embedded block 1 21 and embedded block 22 is fixedly connected to support frame 1 25. One end of fixed block 1 23 and fixed block 24 is fixedly connected to support frame 26. One end of support frame 1 25 is fixedly connected to base 1 27. One end of support frame 26 is fixedly connected to base 28. A positioning block 29 is sleeved inside base 28. A connecting mechanism 3 is provided inside base 1 27. Positioning block 29 is slidably connected to base 28. Positioning block 29 is fixedly connected to base 1 27. Mounting block 201 is fixedly connected to the outer surface of base 1 27 and base 28.

[0021] In this embodiment, by setting embedding block 1 21 and embedding block 22, which can be embedded into the groove 1 at the connection between the torso and lower limbs of the 3D model 1 respectively, embedding block 1 21 and embedding block 22 can be connected to the 3D model 1 in a fitting manner. At the same time, fixing block 1 23 and fixing block 24 are set, which can be embedded into the groove 2 at the connection between the lower limb joints of the 3D model 1, so fixing block 1 23 and fixing block 24 can be connected to the 3D model 1 in a fitting manner. Thus, embedding block 1 21, embedding block 22, fixing block 1 23 and fixing block 24 will not affect the integrity of the 3D model 1 in use. Base 1 27 and base 28 are set, and base 1 27 and base 28 can be spliced ​​into a ring-shaped whole, so that the 3D model 1 can be supported and fixed from the outer side with the cooperation of support frame 1 25 and support frame 26. Example

[0022] like Figures 1-5 As shown, the connecting mechanism 3 includes a pull rod 31, which is sleeved inside the base 27 and slidably connected to the base 27. One end of the pull rod 31 is provided with a limiting piece 32, which is fixedly connected to the pull rod 31. A spring 33 is sleeved on the outer surface of the pull rod 31, and the two ends of the spring 33 are respectively fixedly connected to the outer surface of the limiting piece 32 and the inner wall of the base 27. One end of the pull rod 31 is provided with a pull plate 34, which is fixedly connected to the pull rod 31. One side of the pull plate 34 is provided with a locking rod 35, which is fixedly connected to the pull plate 34. The locking rod 35 is sleeved inside the base 28 and slidably connected to the base 28.

[0023] In this embodiment, a connecting mechanism 3 is provided, which can be used in conjunction with base 1 27 and base 2 28, so that base 1 27 and base 2 28 can be connected conveniently and stably, thus forming a whole for use. A pull plate 34 and a locking rod 35 are provided, and the locking rod 35 can be locked into the interior of base 2 28. Thus, support frame 1 25 can limit base 2 28, ensuring that base 2 28 and base 1 27 will not separate after being connected. At the same time, a spring 33 is provided, which can limit pull rod 31 and limiting piece 32. Thus, with the cooperation of other components of the connecting mechanism 3, the locking rod 35 can be tightly locked into the interior of base 2 28.

[0024] Working principle: like Figures 1-5As shown, in use, the 3D model 1 can be placed in a suitable position first, and then the fixing mechanism 2 can be used to support and fix the 3D model 1. At this time, the pull plate 34 is pulled first, and the pull plate 34 can drive the pull rod 31 to slide inside the base 27. At the same time, the pull rod 31 can also drive the limiting piece 32 to move simultaneously, so that the limiting piece 32 can compress the spring 33, and the spring 33 can generate elastic force. Then, the base 27 drives the support frame 25 and the embedded block 21 and embedded block 22 fixedly connected to one end of the support frame 25 to move, so that the embedded block 21 and embedded block 22 can partially fit into the groove 1 at the connection between the body and the lower limb of the 3D model 1. At the same time, the base 28 also drives the support frame 26 and the fixing block 23 fixedly connected to one end of the support frame 26 and the fixing block 22. When the second block 24 fits into the groove 2 at the lower limb joint connection of the 3D model 1, and the first embedded block 21, the second embedded block 22, the first fixing block 23, and the second fixing block 24 are fully fitted into the interior of the 3D model 1, the first base 27 will drive the positioning block 29 to be embedded into the second base 28 until the first base 27 and the second base 28 are in a close fit. At this time, the pull plate 34 is released, and the elastic force of the spring 33 can be released instantly, and the locking rod 35 is reset, so that the locking rod 35 can be tightly locked into the interior of the second base 28. Thus, the entire fixing mechanism 2 can be in a stable state, and the balance of the 3D model 1 is higher. If it is necessary to further fix the 3D model 1, expansion bolts can be used in conjunction with the mounting block 201. When the mounting block 201 is fixed by the expansion bolts, the 3D model 1 can be in a more stable state.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
