Description

Technical Field

[0001] This utility model relates to the field of additive manufacturing technology, specifically to a chassis structure and a 3D printing device. Background Technology

[0002] The primary function of a 3D printer chassis is to protect the printer's internal components, preventing dust and debris from entering the machine and thus extending the printer's lifespan. Chassis are typically airtight, effectively isolating the printer from external environmental interference. Furthermore, the chassis provides a stable operating environment; the enclosed design reduces noise and vibration, offering a quieter printing experience.

[0003] However, the assembled 3D printer frame presents two problems. On the one hand, the finished 3D printer has a large shipping volume, which increases shipping costs. On the other hand, existing 3D printers are not convenient for placing printing consumables. Therefore, a chassis structure and 3D printer that can be quickly assembled and convenient for placing consumables are needed. Utility Model Content

[0004] This invention provides a chassis structure and a 3D printing device to solve the technical problems of high transportation costs and inconvenience in placing consumables in existing 3D printers.

[0005] To solve the above problems, the chassis structure provided by this utility model adopts the following technical solution: It includes an upper shell, columns, and a printing platform, wherein the number of columns is three, the three columns are evenly distributed, the top ends of the three columns are fixedly connected to the upper shell by bolts, and the bottom ends of the three columns are fixedly connected to the printing platform by bolts. In this method, the upper shell, column, and printing platform can be quickly installed and disassembled, enabling disassembled transportation, saving space and reducing transportation costs.

[0006] It also includes side panels and door panels, with two side panels in total, and the side panels and door panels are respectively located between two adjacent columns to form an enclosed space; The side panels and door panels are detachably connected to the column. By setting the side panels and door panels, the noise during the operation of the 3D printer can be reduced, and a stable working environment can be provided for the 3D printer, such as ensuring that the internal temperature of the 3D printer remains stable.

[0007] The outer wall of the side plate is provided with an elongated hole, and the inner side of the elongated hole is provided with a hanging component that can be flipped outward for hanging consumables. In practical applications, the upper shell is also equipped with a feeding hole. The filament roll is suspended on the hanging component. The filament passes through the feeding hole and enters the 3D printer. The hanging component makes it easy to place the filament when the 3D printer is working.

[0008] Furthermore, the hanging assembly includes a fixed shell, which is an open structure. The fixed shell is located inside the side plate and corresponds to the position of the elongated hole. A movable rod is rotatably connected to the bottom of the fixed shell. The rotation angle range of the movable rod is 0°-90°. That is, when the movable rod is set in the horizontal direction, the angle between the movable rod and the fixed shell is 90°. When the movable rod is not in use, the movable rod is stored in the fixed shell.

[0009] Furthermore, the bottom inner wall of the fixed shell is also provided with a connecting plate, the bottom end of the movable rod has an extension section, and the connecting plate has a protrusion on the side near the extension section of the movable rod. When the movable rod is retracted into the fixed shell, the protrusion limits the extension section of the movable rod to prevent the movable rod from rotating freely to the outside of the side plate.

[0010] Furthermore, the elongated hole, the fixed shell, and the movable rod are all arranged in a vertical direction. In order to ensure that the movable rod can rotate to the outside of the side plate, the opening length of the elongated hole is greater than the length of the rotating end of the movable rod.

[0011] Furthermore, the door panel is mounted on two adjacent posts via a door frame, and a hinge is provided on one side of the door frame, through which the door panel is rotatably connected to the door frame.

[0012] Furthermore, a sealing strip is provided on the outside of the door frame. The sealing strip is made of a flexible material. In application, the sealing strip can be made of EVA foam, which is adhered to the outside of the door frame.

[0013] Furthermore, magnets are provided on both the door panel and the door frame. When the door panel is closed, the magnets on the door panel and the door frame attract each other. The installation of magnets facilitates the opening and closing of the door panel. The door panel will not open when it is not affected by external force or a very small external force, thus improving its practicality.

[0014] Furthermore, a groove is provided at the outer edge of the top of the upper shell, and a hook is provided on the outer wall of the top of the side plate. The hook is adapted to the groove to achieve quick positioning and installation of the side plate.

[0015] Furthermore, the top of the upper shell is also provided with a cover plate, which is fixedly connected to the upper shell, and ventilation holes are provided on the cover plate. The ventilation holes are designed to facilitate heat dissipation or air intake for electrical components installed inside the upper shell.

[0016] This utility model also provides a 3D printing device, including a chassis structure.

[0017] The beneficial effects of the chassis structure provided by this utility model are: This invention, through the combination of an upper shell, columns, and a printing platform, allows for quick installation and disassembly, enabling disassembled transport and saving space, thus reducing transportation costs. Side panels and door panels, positioned between adjacent columns to form enclosed spaces, are detachably connected to the columns. These panels reduce noise during 3D printer operation and provide a stable working environment, such as maintaining a stable internal temperature. The material-holding assembly facilitates the placement of consumables during printer operation. This utility model features a connecting plate on the inner wall of the bottom of the fixed shell, an extension section at the bottom of the movable rod, and a protrusion on the side of the connecting plate near the extension section of the movable rod. When the movable rod is retracted into the fixed shell, the protrusion limits the extension section of the movable rod, preventing the movable rod from rotating freely to the outside of the side plate, thus enhancing its practicality. This utility model incorporates magnets on both the door panel and the door frame. When the door panel is closed, the magnets on the door panel and the door frame attract each other. The magnets facilitate the opening and closing of the door panel, and the door panel can remain closed when it is not affected by external forces or only by very small external forces. This invention achieves rapid positioning and installation of the side panel by setting a groove at the outer edge of the top of the upper shell and setting a hook on the outer wall of the top of the side panel, with the hook matching the groove.

[0021] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0022] The principles of this utility model will be explained in detail below with reference to several representative embodiments.

[0023] An embodiment of the chassis structure and 3D printing device provided by this utility model: Example

[0024] like Figures 1 to 11 As shown, a chassis structure includes an upper shell 1, columns 2, and a printing platform 3. There are three columns 2, which are evenly distributed. The top ends of the three columns 2 are fixedly connected to the upper shell 1, and the bottom ends of the three columns 2 are fixedly connected to the printing platform 3. In practical applications, the top and bottom ends of the columns 2 are provided with threaded holes. The upper shell 1 and the columns 2 are fixedly connected by bolts. In this way, the upper shell 1, columns 2, and printing platform 3 can be quickly installed and disassembled, and can be transported in parts, saving space and reducing transportation costs. like Figure 1 and 2As shown, the chassis structure also includes side panels 5 and door panels 6. There are two side panels 5. The side panels 5 and door panels 6 are respectively located between two adjacent columns 2 to form a closed space. By setting the side panels 5 and door panels 6, the noise during the operation of the 3D printer can be reduced on the one hand, and a stable working environment can be provided for the 3D printer on the other hand, such as ensuring that the internal temperature of the 3D printer remains stable. The top and bottom of the side panels 5 are fixedly connected to the upper shell 1 and the printing platform 3 respectively. like Figure 1 , Figures 8 to 10 As shown, the outer wall of the side plate 5 has an elongated hole 8. The inner side of the elongated hole 8 has a material hanging component that can be flipped outward for hanging consumables. The upper shell 1 also has a feeding hole 17. The consumable roll is suspended on the material hanging component. The consumable passes through the feeding hole 17 and enters the 3D printer. The setting of the material hanging component makes it easy to place consumables when the 3D printer is working. The material hanging component includes a fixed shell 15. The fixed shell 15 has an open structure. The fixed shell 15 is located inside the side plate 5 and corresponds to the position of the elongated hole 8. The bottom of the fixed shell 15 is rotatably connected to a movable rod 16. The rotation angle range of the movable rod 16 is 0°-90°. That is, when the movable rod 16 is set in the horizontal direction, the angle between the movable rod 16 and the fixed shell 15 is 90°. When the movable rod 16 is not used, the movable rod 16 is stored in the fixed shell 15. Example

[0025] like Figure 1-11 As shown, based on Embodiment 1, the bottom inner wall of the fixed shell 15 is also provided with a connecting plate 1501, the bottom end of the movable rod 16 has an extension section, and the connecting plate 1501 has a protrusion 1502 on the side near the extension section of the movable rod 16. When the movable rod 16 is retracted into the fixed shell 15, the protrusion 1502 limits the extension section of the movable rod 16 to prevent the movable rod 16 from freely rotating to the outside of the side plate 5. The elongated hole 8, the fixed shell 15 and the movable rod 16 are all arranged in the vertical direction. In order to ensure that the movable rod 16 can rotate to the outside of the side plate 5, the opening length of the elongated hole 8 is greater than the length of the rotating end of the movable rod 16.

[0026] In one embodiment, the outer wall of the side plate 5 is also provided with a hand-held hole 7. The hand-held hole 7 is provided to facilitate manual handling. In order to keep the hand-held hole 7 closed, a baffle 13 is also installed on the inner wall of the side plate 5 at the position corresponding to the hand-held hole 7. One side of the baffle 13 is movably connected to the side plate 5, and a torsion spring 14 is also provided at the connection between the side plate 5 and the baffle 13. The baffle 13 keeps the hand-held hole 7 closed under the action of the torsion spring 14.

[0027] The cross-section of the side plate 5 is arc-shaped, which can increase the internal space of the 3D printing device. In addition, in order to improve the strength of the side plate 5, the inner wall of the side plate 5 is also provided with reinforcing ribs 502.

[0028] To ensure that the movable rod 16 can rotate to the outside of the side plate 5, the opening length of the elongated hole 8 is greater than the length of the rotating end of the movable rod 16.

In application, the sealing strip 10 can be made of EVA foam, which is adhered to the outside of the door frame 9. Magnets 12 are provided on both the door panel 6 and the door frame 9. When the door panel 6 is closed, the magnets 12 on the door panel 6 and the door frame 9 attract each other. The setting of the magnets 12 facilitates the opening and closing of the door panel 6. The door panel 6 will not open when it is not affected by external force or a very small external force, thus improving its practicality.

[0030] In one embodiment, a groove 101 is provided at the top outer edge of the upper shell 1, and a hook 501 is provided on the top outer wall of the side plate 5. The hook 501 is adapted to the groove 101 to realize the quick positioning and installation of the side plate 5. The top of the upper shell 1 is also provided with a cover plate 4, which is fixedly connected to the upper shell 1. A ventilation hole 401 is provided on the cover plate 4.
