[0027] 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.

[0028] Example: Figure 1-6As shown, this utility model provides a 3D printing layered positioning support structure, including a support platform 1. Several anti-slip seats 11 are fixedly arranged on the lower surface of the support platform 1. By setting the anti-slip seats 11, the stability of the support platform 1 can be improved when it is placed on the printing table of the 3D printing equipment. Assembly holes 12 are provided at the four corners of the support platform 1. Through the assembly holes 12 and the action of the assembly bolts, the support platform 1 can be fixed to the printing table of the 3D printing equipment. Several first support columns 13, second support columns 14, and third support columns 15 are respectively arranged on the upper surface of the support platform 1. By setting the first support columns 13, second support columns 14, and third support columns 15 on the support platform 1... The third support column 15 can support the printed model during the 3D printing process. The support platform 1 is equipped with an installation component 2 for the first support column 13. By setting the installation component 2, the first support column 13 and the second support column 14 can be easily fixed on the support platform 1. It is also easy to disassemble the first support column 13 and the second support column 14. The first support column 13, the second support column 14 and the third support column 15 are equipped with a connecting component 3. By setting the connecting component 3, the third support column 15 can be easily connected to the first support column 13. The connection process is convenient and quick. At the same time, the third support column 15 can be disassembled individually, which is flexible and convenient.

[0029] Mounting component 2 includes several through holes 21. These through holes 21 are equidistantly distributed on the upper surface of the support platform 1. The outer wall of one end of the first support column 13 is in contact with the inner wall of the through hole 21. A movable hole 22 is provided below the through hole 21. One end of the first support column 13 is in contact with the bottom wall of the movable hole 22. By providing the through holes 21 and the movable hole 22, the bottoms of the first support column 13 and the second support column 14 can pass through the through holes 21 and enter the movable hole 22, thereby connecting the first support column 13 and the second support column 14 to the support platform 1.

[0030] Several arc-shaped limiting blocks 23 are slidably arranged on the bottom wall of the movable hole 22. One end of the first support column 13 is located between the arc-shaped limiting blocks 23. An anti-slip pad 24 is fixedly arranged on the other side of the arc-shaped limiting block 23. One side of the anti-slip pad 24 is in movable contact with the outer wall of one end of the first support column 13. By setting the arc-shaped limiting blocks 23 and the anti-slip pad 24, the arc-shaped limiting blocks 23 can clamp the bottom of the first support column 13 or the second support column 14 through the anti-slip pad 24, thereby... Support column 13 and support column 14 are fixed on support platform 1. An arc-shaped guide plate 25 is fixedly installed at one end of the arc-shaped limiting block 23. The arc-shaped guide plate 25 is inclined. By setting the inclined arc-shaped guide plate 25, when the bottom end of support column 13 or support column 14 passes through the insertion hole 21, the bottom end of support column 13 or support column 14 contacts the arc-shaped guide plate 25. As support column 13 or support column 14 is pushed downwards, it is pressed down... Force can cause the arc-shaped guide plate 25 to move horizontally, thereby causing the four arc-shaped limiting blocks 23 to move away from each other. This allows the bottom of the first support column 13 or the second support column 14 to enter the movable hole 22. Several Z-shaped elastic elements 26 are fixedly installed on the peripheral wall of the movable hole 22. One end of the Z-shaped elastic element 26 is fixedly connected to one side of the arc-shaped limiting block 23. By setting the Z-shaped elastic element 26, the Z-shaped elastic element 26 can cause the arc-shaped limiting block 23 to move horizontally through its own elasticity. The four arc-shaped limiting blocks 23 are in a state of mutual proximity, which can clamp the bottom end of the first support column 13 or the second support column 14. A guide block 27 is fixedly installed on the other end of the arc-shaped limiting block 23. The guide block 27 is slidably installed on the bottom wall of the movable hole 22. By setting the guide block 27, the guide block 27 can slide horizontally on the bottom wall of the movable hole 22, thereby guiding the arc-shaped limiting block 23 in the horizontal direction and keeping the arc-shaped limiting block 23 moving in the horizontal direction.

[0031] The connecting assembly 3 includes external threaded studs 32. Rotating rings 31 are rotatably mounted on each of the first support post 13, the second support post 14, and the third support post 15. Several external threaded studs 32 are arranged in a ring array and fixed to the outer wall of the rotating rings 31. Internal threaded sleeves 33 are rotatably mounted on the outer wall of each external threaded stud 32. By configuring the rotating rings 31, external threaded studs 32, and internal threaded sleeves 33, when the rotating ring 31 is manually rotated, the external threaded studs 32 on the rotating ring 31 can rotate in a circular motion. When two first support posts 13 or one first support post 15 are rotated... After the external threaded studs 32 on a No. 2 support column 14 or a No. 3 support column 15 are aligned, the internal threaded sleeve 33 can be rotated to the corresponding external threaded stud 32 by rotating the internal threaded sleeve 33. This achieves the connection of two No. 1 support columns 13, or the connection of No. 2 support column 14 with No. 1 support column 13, or the connection of No. 3 support column 15 with No. 2 support column 14, or the connection of No. 3 support column 15 with No. 1 support column 13. The outer wall of the internal threaded sleeve 33 is provided with anti-slip textures 34, which facilitates the manual rotation of the internal threaded sleeve 33 by the operator.

[0032] Working principle: When installing support column 13 and support column 14, the operator first vertically inserts them into the corresponding insertion holes 21. The bottom end of support column 13 or support column 14 passes through the insertion hole 21 and contacts the four corresponding arc-shaped guide plates 25. The downward thrust of support column 13 or support column 14, through the four arc-shaped guide plates 25, causes the four arc-shaped limiting blocks 23 to move away from each other. Simultaneously, the Z-shaped elastic element 26 contracts until support column 13 or support column 14 is vertically inserted into the corresponding movable hole 22. After the bottom is reached, the four Z-shaped elastic elements 26 extend and reset, causing the four arc-shaped limiting blocks 23 to approach each other. The four arc-shaped limiting blocks 23 clamp the bottom end of the first support column 13 or the second support column 14 through the corresponding anti-slip pads 24, thus facilitating the quick installation of the first support column 13 and the second support column 14. At the same time, the first support column 13 and the second support column 14 can be removed by pulling them in the opposite direction, improving the convenience of the installation and disassembly of the first support column 13 and the second support column 14. It also makes it convenient to select the appropriate number of the first support column 13 and the second support column 14 on the support platform 1 according to the printing situation.

[0033] Subsequently, the third support column 15 is placed around the first support column 13, and the external threaded post 32 on the first support column 13 is aligned with the external threaded post 32 on the third support column 15. Then, the internal threaded sleeve 33 is rotated, and one internal threaded sleeve 33 is threaded onto another external threaded post 32. At this time, the third support column 15 is fixed around the first support column 13, thus facilitating the installation of the third support column 15. This makes it easier to set up the corresponding layered support according to the printing situation, so that the support matches the shape of the printed model and meets the support requirements of the printed model.

[0034] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
