[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] The present invention provides a 3D printing demonstration device for practical training and teaching, comprising a demonstration box 1 and a 3D printing device 11 located at the inner top of the demonstration box 1, and further comprising a printing table 2. The bottom of the demonstration box 1 is provided with a through slot 12, and the through slot 12 extends to the rear side of the demonstration box 1. The printing table 2 is located in the demonstration box 1 and is in a horizontal position. An adjustment mechanism 3 for controlling the rotation and tilt of the printing table 2 is provided at the bottom of the printing table 2, and a pressure rod 4 for operating the adjustment mechanism 3 is provided at the through slot 12 of the demonstration box 1.

[0025] After the 3D product is printed, the demonstrator can open the lid of the demonstration box 1, and then press, lift, or pull the pressure rod 4 to the left or right to make the printing table 2 move the printed product in the demonstration box 1 to tilt at multiple angles and display it at left and right angles, so that students can observe the 3D printed product from multiple angles, so as to have a deeper understanding of the detailed features of the 3D printed product.

[0026] In a further preferred embodiment, the adjustment mechanism 3 includes a baffle 31, a support member 32 and a support rod 33. The baffle 31 is placed horizontally below the printing table 2. Two support members 32 are provided, and the two support members 32 are symmetrically arranged at both ends of the baffle 31. The bottoms of the two support members 32 are fixedly connected to the inner bottom of the demonstration box 1. The two ends of the baffle 31 are rotatably connected to the two support members 32 respectively. The support rod 33 is vertically arranged in the middle section of the baffle 31 and is located at the bottom of the printing table 2. The top of the support rod 33 is fixedly connected to the bottom of the printing table 2, and the bottom of the support rod 33 passes through the baffle 31 and extends a distance below the baffle 31 to form an extended end 34. The support rod 33 is rotatably connected to the baffle 31, and the end of the pressure rod 4 facing the front side of the demonstration box 1 is fixedly connected to the bottom extended end 34 of the support rod 33;

[0027] Because both ends of the baffle 31 are rotatably connected to the two support members 32, when the end of the pressure rod 4 is pressed, the front end of the pressure rod 4 will drive the support rod 33 and the printing table 2 to tilt toward the rear side of the demonstration box 1 with the rotational connection between the baffle 31 and the two support members 32 as the axis, so that the product on the printing table 2 can be slightly tilted for students to observe;

[0028] When the end of the pressure rod 4 is lifted upward, the support rod 33 can drive the printing table 2 to tilt toward the front side of the demonstration box 1, so that the printed product can be observed from the top of the product from a bird's-eye view.

[0029] When the end of the pressure rod 4 is held and pulled to the left or right, the pressure rod 4 can drive the printing table 2 to rotate to the left or right direction with the support rod 33 and the baffle 31 as the axis, so that the printed product can be observed by the trainee in the left or right direction;

[0030] Secondly, when pressing or lifting the end of the pressure rod 4, you can also pull the pressure rod 4 slightly to the left or right, so that the pressure rod 4 can drive the printing table 2 to be tilted and rotate to the left or right, so that students can observe from all directions.

[0031] In a further preferred embodiment, a limit block 5 for limiting the pressure rod 4 is provided on the rear side of the demonstration box 1. The top of the limit block 5 is rotatably connected to the rear side of the demonstration box 1. The bottom end of the limit block 5 is provided with a groove 51 for the pressure rod 4 to be inserted in a horizontal state. The position of the groove 51 on the limit block 5 is the same as the position of the pressure rod 4 in the horizontal state, so that the bottom of the limit block 5 has a C-shaped structure.

[0032] When a 3D printed product is needed, the limit block 5 can be flipped downward, and at the same time, the pressure rod 4 can be pulled toward the opening direction of the groove 51 of the limit block 5, so that the pressure rod 4 will not block the limit block 5. Then, the pressure rod 4 is pulled toward the limit block 5, so that the pressure rod 4 is gradually inserted into the groove 51 of the limit block 5, thereby limiting the upward and downward movable state of the pressure rod 4. Since the position of the groove 51 on the limit block 5 is the same as the position of the pressure rod 4 in the horizontal state, the pressure rod 4 will drive the printing table 2 to be in a horizontal state after being inserted into the groove 51 of the limit block 5, so that the printing table 2 can cooperate with the 3D printing device 11 for 3D printing.

[0033] In a further preferred embodiment, a silicone pad is provided on the groove 51 of the limit block 5. The silicone pad provided on the groove 51 of the limit block 5 can increase the friction force when the pressure rod 4 is engaged with the groove 51 of the limit block 5, so as to prevent the pressure rod 4 from falling out of the groove 51. At the same time, combined with the design of the groove 51 on the limit block 5, the movement state of the pressure rod 4 on the left and right sides can be restricted.

[0034] In a further preferred embodiment, a magnetic stone 6 is provided on the rear side of the demonstration box 1, and a metal sheet 61 that can be magnetically adsorbed with the magnetic stone 6 is provided on the side of the demonstration box 1 after the limit block 5 is flipped upward. When the limit block 5 is not used to limit the pressure rod 4, the limit block 5 can be flipped upward so that the metal sheet 61 on the limit block 5 is attached to the magnetic stone 6 on the rear side of the demonstration box 1 and produces magnetic adsorption, so that the limit block 5 remains in a flipped downward state and avoids obstruction to the movement of the pressure rod 4 due to the downward flipping.

[0035] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
