AI Technical Summary
Replacing the printing plate in a traditional 3D printer's printing base is complex, time-consuming, and labor-intensive, and the fixing structure is prone to loosening, affecting printing accuracy and quality.
It adopts a combination design of elastic fasteners, driving components and linkage components, and realizes the synchronous movement of the two fixed structures through a single operating point. Combined with the inclined surface design and limit plate, it simplifies the replacement process and enhances the fixing stability.
It enables quick replacement of the printing disk, improves operational convenience and printing accuracy, reduces printing failures caused by looseness, and improves 3D printing efficiency and quality.

2. The quick change 3D printer print bed of claim 1, wherein, The elastic fastener (3) includes two fixing plates (31) respectively set on the top of the bearing plate (1); a slide rod (32) set between the two fixing plates (31); a slider (33) slidably sleeved on the outer wall of the slide rod (32); a spring (34) sleeved on the outer wall of the slide rod (32) and connected at both ends to the outer wall of one of the fixing plates (31) and the slider (33) respectively; and a fixing frame (35) set on the top of the slider (33), the fixing frame (35) being a J-shaped plate structure.
3. The quick change 3D printer build platform of claim 2, wherein, The driving component (4) includes a sliding sleeve (41) disposed on the top of the outer wall of the bearing plate (1); a slide bar (42) that can slide through the sliding sleeve (41); a handle (43) disposed on the outer wall of the slide bar (42); two hinge seats (44) respectively disposed on both sides of the outer wall of the slide bar (42) and two hinge seats respectively disposed on the outer walls of the two opposing sliders (33); the two opposing hinge seats (44) are hinged together by a connecting rod (45).
4. The quick change 3D printer build platform of claim 3, wherein, The linkage (5) includes a gear (51) rotatably mounted on the top of the support plate (1); and two toothed plates (52) respectively mounted on opposite sides of the two slide bars (42), with the two toothed plates (52) being staggered.
5. The quick change 3D printer build platform of claim 2, wherein, The contact surfaces of the printing plate (2) and the fixing frame (35) are both provided with inclined surfaces.
