As shown in fig. 1 to 7, an embodiment of the present invention provides a 3D printer forming platform 100.
As shown in fig. 1, the 3D printer forming platform 100 includes a printing plate 110, a connecting rod 120, and a support 130, wherein the support 130 is connected with the printing plate 110 through the connecting rod 120;
a first opening and a first chamber are formed on a first side surface of the support 130, the first side surface is a side surface of the support 130 facing the printing plate 110, the first opening is communicated with the first chamber, a clasping assembly 140 is arranged in the first chamber, and the clasping assembly 140 comprises a first through hole; the first end of the connecting rod 120 extends into the first through hole, the aperture of the first through hole is adjustable, so that the first end of the connecting rod 120 is in a movable state or an immovable state in the first through hole, and the second end of the connecting rod 120 is connected with the printing flat plate 110.
In the embodiment of the present invention, as shown in fig. 1, the support 130 of the 3D printer forming platform 100 is connected to the printing plate 110 through the connecting rod 120. A first cavity is formed in the supporting member 130, a clasping assembly 140 is arranged in the first cavity, the clasping assembly 140 comprises a first through hole, and the first end of the connecting rod 120 extends into the first cavity and is accommodated and limited in the first through hole of the clasping assembly 140. Wherein the first end of the connecting rod 120 may be represented as an upper end as shown in fig. 1, and the second end of the connecting rod 120 may be represented as a lower end as shown in fig. 1.
The first through hole of the clasping assembly 140 has an adjustable aperture so that the first end of the connecting rod 120 is in a movable state or an immovable state in the first through hole. It can be understood that, under the condition that the aperture of the first through hole is larger, that is, the aperture of the first through hole is larger than the diameter of the first end of the connecting rod 120, the first end of the connecting rod 120 is in a movable state in the first through hole, and the connecting rod 120 can change the angle between the connecting rod and the supporting member 130 through swinging, so as to drive the printing flat plate 110 to be adjusted to be parallel to the blasting screen of the 3D printer; when the aperture of the first through hole is reduced to be closely matched with the first end of the connecting rod 120, a certain pressure can be applied to the first end of the connecting rod 120 by the hole wall of the first through hole, so that the first end of the connecting rod 120 can not move in the first through hole and can be locked.
In the embodiment of the present invention, the first end of the connecting rod 120 is defined in a first through hole of the clasping assembly 140 and is fixedly connected to the supporting member 130, and the aperture of the first through hole is adjustable, so that the first end of the connecting rod 120 is in an active state or an inactive state. In the active state, the connecting rod 120 can be operated to level the angle of the printing plate 110, and then the first end of the connecting rod 120 can be locked by reducing the aperture of the first through hole, so that the leveled angle of the connecting rod 120 is fixed and cannot be changed, and the leveling effect of the 3D printer forming platform 100 is improved.
Optionally, as shown in fig. 2, the clasping assembly 140 includes a clasping sleeve 141 and a first locking member 142, the first through hole is formed in the clasping sleeve 141, and the first locking member 142 is connected to the clasping sleeve 141 and is used for adjusting the aperture of the first through hole.
In this embodiment, the clasping assembly 140 comprises a clasping sleeve 141 and a first locking member 142. As shown in fig. 2, the clasping sleeve 141 may be a ring sleeve with a through slot, the first through hole is formed in the middle of the ring sleeve, and the first locking member 142 may change the opening width of the through slot, so as to adjust the aperture of the first through hole.

Optionally, as shown in fig. 1, the 3D printer forming platform 100 further includes a sealing ring 150, and the sealing ring 150 is sleeved on the connecting rod 120 and is used for sealing the first opening.
Because the first end of the connecting rod 120 extends into the clasping component 140 in the first chamber through the first opening, in order to enable the connecting rod 120 to swing at any angle and freely move in the first through hole when the first end of the connecting rod 120 is in a movable state, the caliber of the first opening is usually larger than the diameter of the connecting rod 120. However, during or after the 3D printing process of the 3D printer forming platform 100 is completed, a large amount of photosensitive resin remains on the printing platform 110 and around the printing platform, and if the subsequent 3D printer forming platform 100 is improperly placed, for example, when the printing platform is placed upside down as shown in fig. 4, the remaining photosensitive resin flows into the first cavity and the first through hole through the first opening and is cured, so that the first end of the connecting rod 120 is not movable, thereby affecting the leveling of the printing platform 110.
In this embodiment, as shown in fig. 1 and 4, a sealing ring 150 is disposed around the connecting rod 120 to close the first opening, so as to prevent the photosensitive resin and other substances from entering the first chamber. The seal ring 150 is mostly made of soft rubber, and can be tightly fitted with the connecting rod 120, so that the connecting rod 120 is not hindered from swinging when the connecting rod 120 swings at the movable first end, and the connecting rod 120 can be always attached to ensure a sealing effect.
