[0002] A mathematical model is a mathematical structure that is generally or approximately expressed using mathematical language or a physical model with reference to the characteristics or quantitative dependencies of a certain system of things, and assists in expressing mathematical relationships. Mathematical models include solid geometric models. A 3D printer is a device of rapid prototyping technology that can construct three-dimensional objects based on digital model files and is often used in the modeling of mathematical models. In summary, the problems existing in the prior art are: when a 3D printer is used, the model is established by controlling the movement position of a printing gun through data. The printing gun is equipped with a nozzle through bolts. The size of the nozzle will be replaced according to the fineness of the model, and the nozzle will be worn out after long-term use and needs to be replaced. When replacing, professional tools are required to disassemble multiple bolts. After the bolts are removed, the hands need to be protected before holding the nozzle. The nozzle is hot and can easily cause safety hazards if touched directly by hand. This nozzle replacement method takes a long time and has low installation performance, which is not convenient enough. However, the 3D printer used in the existing mathematical model modeling does not have a component for conveniently replacing the nozzle as needed. This technology is sometimes also called a mathematical model modeling device, so a mathematical model modeling device is proposed to solve the above problems. Utility Model Content

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4As shown, a mathematical model modeling device provided by an embodiment of the utility model includes a 3D printer 1 and a printing gun 2. The printing gun 2 is arranged on the surface of the 3D printer 1. The bottom of the printing gun 2 is fixedly connected to a mounting shell 3. The inner cavity of the mounting shell 3 is movably connected to a device shell 4. The inner cavity of the device shell 4 is fixedly connected to a nozzle 5. A limiting device 6 is arranged inside the device shell 4.

[0022] refer to Figure 4 The limiting device 6 includes two limiting blocks 601, and the opposite sides of the two limiting blocks 601 penetrate the device shell 4 and extend to the outside of the inner cavity of the device shell 4. A stabilizing hole 602 is opened on the surface of the limiting block 601. The opposite sides of the two limiting blocks 601 are fixedly connected with springs 603, and the opposite sides of the two springs 603 are fixedly connected to the inner cavity of the device shell 4.

[0023] With the above solution, by providing the limiting device 6 , when the nozzle 5 moves to the position where it is installed on the printing gun 2 , the limiting device 6 has a limiting effect on the position of the nozzle 5 .

[0024] refer to Figure 4 The bottom of the limit block 601 is movably connected to the two extrusion rotating rods 7 through a rotating shaft.

[0025] The above solution is adopted: by setting an extrusion rotating rod 7, when the extrusion rotating rod 7 moves, it can drive the moving block 8 to move along the inner cavity of the moving frame 9, and when the extrusion rotating rod 7 moves, it will rotate through the rotating shaft, and when the extrusion rotating rod 7 rotates, it can drive the limit block 601 to move.

[0026] refer to Figure 4 The top of the extrusion rotating rod 7 is movably connected with a moving card block 8 through a rotating shaft, the inner cavity of the device shell 4 is fixedly connected with a moving frame 9 used in conjunction with the moving card block 8, and the surface of the moving card block 8 is movably connected with the inner cavity of the moving frame 9.

[0027] The above solution is adopted: by setting the moving block 8 and the moving frame 9, when the extrusion rotating rod 7 moves, the moving block 8 will be driven to move along the inner cavity of the moving frame 9. The coordinated use of the moving block 8 and the moving frame 9 has a limiting effect on the moving position of the extrusion rotating rod 7.

[0028] refer to Figure 4 The inner cavity of the device shell 4 is movably connected to two control frames 10, the bottom of the control frame 10 passes through the device shell 4 and extends to the outside of the inner cavity of the installation shell 3, and the top of the control frame 10 is movably connected to the surface of the extrusion rotating rod 7 through a rotating shaft.

[0029] The above solution is adopted: by setting the control frame 10, pulling the two control frames 10, when the control frame 10 moves, the four extrusion rotating rods 7 can be driven to rotate and move at the same time.

[0030] refer to Figure 4 Two stabilizing rods 11 used in conjunction with the stabilizing holes 602 are fixedly connected to the inner cavity of the device shell 4 , and the surfaces of the stabilizing rods 11 are in contact with the inner cavity of the stabilizing holes 602 .

[0031] The above solution is adopted: by setting the stabilizing rod 11 and the stabilizing hole 602, when the limit block 601 moves, the stabilizing hole 602 can be driven to move along the surface of the stabilizing rod 11. The coordinated use of the stabilizing hole 602 and the stabilizing rod 11 has a limiting effect on the moving position of the limit block 601.

[0032] refer to Figure 3 The front and rear sides of the inner cavity of the mounting shell 3 are both provided with limiting grooves 12 for use with the limiting block 601 , and the surface of the limiting block 601 is in contact with the inner cavity of the limiting groove 12 .

[0033] The above scheme is adopted: by setting the limit groove 12, when the device shell 4 moves to the inner cavity of the installation shell 3, the control frame 10 is released, and the restoring force generated by the spring 603 restoring its shape will drive the limit block 601 to be stuck into the inner cavity of the limit groove 12. The coordinated use of the limit block 601 and the limit groove 12 has a limiting effect on the position of the device shell 4.

[0034] The working principle of this utility model:

[0035] During use, when the 3D printer 1 used for mathematical model building needs to conveniently replace the nozzle 5 as needed, the user first removes the nozzle 5 that needs to be replaced, and then pulls the control frame 10 to the opposite side of the two control frames 10. When the control frame 10 moves, it will drive the extrusion rod 7 to move. When the extrusion rod 7 moves, it will drive the moving block 8 to move along the inner cavity of the moving frame 9. When the moving block 8 moves, the extrusion rod 7 will rotate through the rotating shaft. When the extrusion rod 7 rotates, it will drive the two limit blocks 601 to move toward each other. When the limit block 601 moves, it will drive The stabilizing hole 602 moves along the surface of the stabilizing rod 11. When the limit block 601 moves, the force generated causes the spring 603 to undergo elastic deformation. When the limit block 601 is completely moved to the inner cavity of the device shell 4, the device shell 4 is moved into the inner cavity of the mounting shell 3, and then the two control frames 10 are released. The restoring force generated by the spring 603 restoring its shape will drive the limit block 601 to be stuck into the inner cavity of the limit groove 12. The coordinated use of the limit block 601 and the limit groove 12 has a limiting effect on the position of the device shell 4 and the nozzle 5. At this time, the 3D printer 1 used for mathematical model modeling can complete convenient replacement of the nozzle 5 as needed.

[0036] To sum up: the mathematical model building device, by setting the limit device 6, the limit block 601, the stabilizing hole 602, the spring 603 and the limit groove 12 for coordinated use, solves the problem of the existing 3D printer building the model by controlling the moving position of the printing gun through data when using the existing 3D printer. The printing gun is equipped with a nozzle through bolts. The size of the nozzle will be replaced according to the fineness of the model, and the nozzle will be worn out after long-term use and needs to be replaced. When replacing, professional tools are needed to disassemble multiple bolts. After the bolts are removed, the hands need to be protected before holding the nozzle. The nozzle is hot and it is easy to cause safety hazards if touched directly by hand. This nozzle replacement method takes a long time and has low installation performance, which is not convenient enough. However, the 3D printer used for existing mathematical model modeling does not have a component for conveniently replacing the nozzle as needed.
