Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a lifting platform for 3D printing. Background Technology

[0002] A 3D printer, also known as a three-dimensional printer, is a type of cumulative manufacturing technology, or rapid prototyping technology. It uses a digital model file as a basis and employs special waxes, powdered metals, or plastics and other adhesive materials to create three-dimensional objects by printing layers of adhesive materials. Currently, 3D printers are used to manufacture products, using a layer-by-layer printing method to construct objects. The stand for a 3D printer is crucial for maintaining the stable operation of the printer, but traditional 3D printer stands cannot adjust the height of the printer and are inconvenient to move, failing to meet the needs of practical use.

[0003] A user-friendly 3D printer base with patent number 201721093600.2 includes a housing. A motor is fixedly connected to the bottom of the inner cavity of the housing. A toothed block is movably connected to the top of the motor shaft, which passes through the housing and extends to the outside of the housing. A fixing block is movably connected to the surface of the motor shaft. The bottom of the fixing block is fixedly connected to the top of the housing. A first connecting rod is fixedly connected to the left side of the fixing block. A first vertical rod is fixedly connected to the right side of the top of the first connecting rod.

[0004] The 3D printer base mentioned above has a fixed height, which requires a certain height from the user. It cannot be adjusted according to the operator's actual height, which is very inconvenient. Although the 3D printer base is equipped with casters to make it easy to move, it does not have a braking structure, which makes it easy to move when the 3D printer is working, resulting in inaccurate printing.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] To make the content of this utility model easier to understand, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0022] according to Figures 1 to 4 As shown, a lifting platform for 3D printing includes a support frame 1, characterized in that the support frame 1 is provided with a lifting device 2, the lifting device 2 is provided with a quick release device 3, and a pair of storage devices 4 are symmetrically arranged on both sides of the support frame 1, and the storage devices 4 are provided with a limiting device 5.

[0023] In this embodiment, the lifting device 2 includes a lifting motor 201 installed below the support frame 1. This motor is a reversible motor to enable the vertical movement of the lifting platform. A lifting sleeve 202 is fixedly installed above the support frame 1, ensuring it is perpendicular and stable. Next, one end of the lifting threaded rod 204 is fixedly connected to the output end of the lifting motor 201, and the other end passes through the lifting sleeve 202 and is rotatably mounted on top of the lifting sleeve 202 to ensure smooth rotation. A screw nut pair 205 is installed on the lifting threaded rod 204. This nut pair fits tightly with the threaded rod and can move up and down as the threaded rod rotates.

[0024] In this embodiment, the quick-release device 3 includes symmetrically installed lifting connecting rods 206 on both sides of the lead screw nut pair 205. These connecting rods pass through the strip-shaped through holes 203 on the lifting sleeve 202 and are fixedly connected to the lifting fixing plate 207 at their ends. Subsequently, a quick-release fixing plate 301 is installed on the outer wall of the lifting fixing plate 207, and a quick-release connecting rod 302 is inserted thereon. One end of the quick-release connecting rod 302 is fixedly connected to the lifting plate 303, and the other end is machined with a quick-release thread 304 for installing quick-release nut one 305 and quick-release nut two 306. By rotating these two nuts, the tightness between the lifting plate 303 and the quick-release fixing plate 301 can be easily adjusted to achieve quick disassembly and assembly.

[0025] In this embodiment, the storage device 4 includes connecting rod 1 401 and connecting rod 2 402 symmetrically installed on both sides of the support frame 1, with a support groove 403 fixed at their ends.

A limiting connecting frame 501 is fixed above the support groove 403, and a limiting rod 502 is inserted onto it. One end of the limiting rod 502 is fixed to a limiting pull plate 503, and the other end is inserted into the limiting groove 407. A baffle 504 is installed on the limiting rod 502, and a limiting spring 505 is provided between the baffle and the limiting connecting frame 501. By changing the relative position between the limiting rod 502 and the limiting groove 407, the angle of the caster wheel 406 can be adjusted, thus stabilizing the device. Conversely, supporting the caster wheel 406 facilitates movement of the device.

[0027] In summary, this utility model employs a motor drive and a threaded transmission mechanism to ensure the smoothness and accuracy of lifting; the quick-release device simplifies the replacement and maintenance process of the lifting platform; and the combination of the storage device and the limiting device enables convenient movement and stable fixation of the lifting platform.
