The first presser 220 is not connected to the cantilever 300 as an example. When the printing platform is installed, the printing platform assembly 100 is moved into the accommodating space between the first pressing block 220 and the fixed assembly 210, gaps are formed between the first pressing block 220 and the fixed assembly 210 and between the first pressing block 220 and the printing platform assembly 100, the printing platform assembly 100 can move relative to the first pressing block 220 and the fixed assembly 210 to adjust the position, then the fastening assembly 230 is adjusted to enable the fastening assembly 230 to act on the fixed assembly 210 and/or the first pressing block 220, the fixed assembly 210 and the first pressing block 220 are close to each other, the accommodating space is reduced, further, the gap between the first pressing block 220 and the fixed assembly 210 and the printing platform assembly 100 is reduced, the locking degree of the printing platform assembly 100 is enhanced, when the gap between the first pressing block 220 and the fixed assembly 210 and the printing platform assembly 100 disappears, the first pressing block 220 and the fixed assembly 210 press the printing platform assembly 100 from two sides, and the printing platform assembly 100 is clamped.
In some embodiments, when the first pressing block 220 and the fixing component 210 clamp the printing platform component 100, the first pressing block 220 and the fixing component 210 abut against each other at the same time, so that the stability of the positions of the first pressing block 220 and the fixing component 210 is ensured, and unstable clamping caused by relative movement of the first pressing block 220 and the fixing component 210 is avoided. The movable connection embodiment of the first pressing block 220 and the fixing member 210, and the abutting embodiment of the first pressing block 220 and the fixing member 210 will be exemplified and described in detail later.
The fastening assembly 230 is used to make the first pressing block 220 and the fixing assembly 210 approach or move away from each other, and the fastening assembly 230 may be implemented in various ways, for example, the fastening assembly 230 is a bolt, which is movably threaded on the fixing assembly 210 and then is screwed on the first pressing block 220, and by screwing the bolt, pushing the first pressing block 220 to approach or move away from the fixing assembly 210 through a screw pushing action, the printing platform assembly 100 is clamped and loosened. Alternatively, a structure in which the first pressing block 220 is close to or far from the fastening assembly 230 of the fixing assembly 210 by pressing the first pressing block 220 to different degrees will be described in detail below, so as to fix the printing platform assembly 100 more quickly.
In addition, the use of the connecting mechanism is not limited to the 3D printer, and is not limited to the fixed printing platform assembly 100, and the connecting mechanism can be used in any two scenes that need to be connected, for example, the connecting mechanism can be used for fixing the trough, for example, the fixing assembly 210 is used for connecting to the base of the 3D printer, and the fixing assembly 210 and the first pressing block 220 are used for clamping the trough, so that the trough can be stably fixed on the base, and the trough is prevented from being unstable in position during the demolding process of the model.
According to the connecting mechanism, the printing platform device and the 3D printer, the printing platform assembly is fixed through the fixing assembly and the first pressing block in an extruding mode, so that the printing platform assembly is stable in position and not prone to loosening, and the mounting process is simple to operate.
