Description

Technical Field

[0001] This utility model relates to the field of 3D printing, specifically a lifting platform for a 3D printer. Background Technology

[0002] A 3D printer, also known as a three-dimensional printer (3DP), is a machine that uses a cumulative manufacturing technology, or rapid prototyping technology. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are many ways to stack thin layers, and a wide variety of media can be used for printing, from a wide range of plastics to metals, ceramics, and rubber and other adhesive materials. Three-dimensional objects are created by printing layers of adhesive materials.

[0003] In existing technologies, printers typically have an adjustable mechanism to adjust the height of the printer's operating platform. However, existing lifting platforms are unstable during lifting, which can affect the lifespan of the equipment. Furthermore, the printing platen and lifting platform are often fixed in place, making it inconvenient to disassemble and clean them, which is very inconvenient when using the equipment. Therefore, in view of the above situation, there is an urgent need to develop a lifting platform for 3D printers to overcome the shortcomings in current practical applications. Utility Model Content

The lifting mechanism includes: a control component, a guide component, and a stabilizing component. The control component is disposed between the lifting platform and the mounting base, and a guide component is also disposed between the control component and the mounting base for cooperating with the control component to achieve the raising and lowering of the lifting platform.

[0009] As a further embodiment of this utility model: the stabilizing component includes: positioning posts and limiting balls. The positioning posts are symmetrically arranged inside the mounting base, with their bottom ends fixedly connected to the mounting base and penetrating through the guide frame on the same side. A plurality of limiting balls that abut against the outer wall of the positioning posts are rolledly connected inside the guide frame.

[0010] As a further embodiment of this utility model: the disassembly and assembly mechanism includes: a telescopic component, a control plate, a control tube, a piston component, a positioning protrusion, a locking tube, a sensing piston, a locking insert plate, and a insertion slot.
