[0050] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0051] Example

[0052] Figure 1 Schematic diagram of the structure of a 3D printer 1000 in one embodiment of the present application; Figure 2 for Figure 1 A top view of a portion of the structure of the 3D printer 1000 in the illustrated embodiment; Figure 3 for Figure 1 Schematic diagram of the assembled state of the leveling assembly 100, the target component 200a and the base component 300a in the illustrated embodiment.

[0053] See also Figure 1 and Figure 2 An embodiment of the present application provides a 3D printer 1000 , including a leveling component 100 , a printing platform 200 , and a base 300 .

[0054] See also Figure 3 The leveling assembly 100 is used to support the target part 200a on the base part 300a. The printing platform 200 includes the target part 200a, and the base 300 includes the base part 300a. During use, the distance between the printing platform 200 and the base 300 is adjusted by adjusting the leveling assembly 100. For example, the leveling assembly 100 can be adjusted to reduce the distance between the printing platform 200 and the base 300, thereby lowering the printing platform 200 relative to the base 300, or to increase the distance between the printing platform 200 and the base 300, thereby raising the printing platform 200 relative to the base 300.

[0055] In some embodiments, as Figure 1 and Figure 2 As shown, the base 300 includes a base body 301 and a slide 302, and the slide 302 is movable relative to the base body 301. The printing platform 200 is connected to the slide 302, and the printing platform 200 is used to carry the consumables and shape them. Optionally, the printing platform 200 includes a heating plate 201 and a carrying plate 202, the heating plate 201 is connected to the slide 302, and the carrying plate 202 is connected to the side of the heating plate 201 away from the slide 302. In this embodiment, the target part 200a can be the heating plate 201, and the base part 300a can be the slide 302. The leveling assembly 100 supports the heating plate 201 on the slide 302 to adjust the distance between the heating plate 201 and the slide 302, thereby changing the distance between the carrying plate 202 and the base 300.

[0056] In some embodiments, as Figure 4 As shown, the number of the leveling components 100 is four, and the four leveling components 100 are arranged in a rectangular manner so that the printing platform 200 can be adjusted separately by adjusting each leveling component 100 (see FIG. Figure 1 ) and the distance between the four corners of the base 300. For example, by adjusting each leveling assembly 100, the side surface of the supporting plate 202 away from the base 301 and the side surface of the base 301 close to the supporting plate 202 can be parallel.

[0057] Figure 4 for Figure 1 A cross-sectional view of a portion of the leveling assembly 100, the target member 200a, and the base member 300a in the illustrated embodiment; Figure 5 for Figure 1 a perspective view of the leveling assembly 100 in the illustrated embodiment; Figure 6 for Figure 1 Exploded view of the leveling assembly 100 in the illustrated embodiment.

[0058] See also Figures 4 to 6 The leveling assembly 100 in this embodiment includes a support tube 10 and a jackscrew 20. The support tube 10 has a first end 11 and a second end 12 along the axial direction. The first end 11 is connected to the target member 200a, and the second end 12 is threadedly connected to the base member 300a. The jackscrew 20 can move axially relative to the base member 300a to adjust the distance between the target member 200a and the base member 300a. The jackscrew 20 is connected to the second end 12 of the support tube 10 and can move axially relative to the support tube 10 until it contacts the base member 300a.

[0059] In the leveling assembly 100, the first end 11 of the support tube 10 is connected to the target member 200a, and the second end 12 is threadedly connected to the base member 300a. This allows the support tube 10 to be fixed relative to both the target member 200a and the base member 300a, thereby supporting the target member 200a on the base member 300a. Furthermore, by rotating the second end 12 relative to the base member 300a, the support tube 10 can be moved axially relative to the base member 300a, thereby driving the target member 200a to move relative to the base member 300a and changing the distance between the target member 200a and the base member 300a. Furthermore, because the push screw 20 is connected to the second end 12 of the support tube 10 and can axially abut the base member 300a, after adjustment, the push screw 20 prevents the support tube 10 from moving toward the base member 300a. This improves the reliability of the support tube 10's support of the target member 200a and secures the target member 200a more securely relative to the base member 300a.

[0060] Optionally, the jackscrew 20 is threadedly connected to the second end 12 of the support tube 10. During use, the jackscrew 20 can be rotated relative to the second end 12, so that one end of the jackscrew 20 protrudes from the second end 12 and the end of the jackscrew 20 protruding from the second end 12 can axially abut the base member 300a. In other embodiments, the jackscrew 20 and the second end 12 of the support tube 10 can also be connected using a ball and ball lock groove or other connection methods.

[0061] During use, the axial direction of the support tube 10 can be vertical, so that the leveling assembly 100 can adjust the height of the target member 200a relative to the base member 300a. Specifically, when it is necessary to raise a corner of the target member 200a, the support tube 10 corresponding to the corner can be operated to rotate the second end 12 relative to the base member 300a, so that the first end 11 is raised axially relative to the base member 300a, thereby driving the target member 200a to be raised relative to the base member 300a. Then, the top screw 20 is moved axially relative to the support tube 10 toward the side closer to the base member 300a. For example, when the top screw 20 is threadedly connected to the second end 12, the top screw 20 is rotated relative to the second end 12 until the top screw 20 axially contacts the base member 300a, thereby preventing the support tube 10 from sliding relative to the base member 300a. When it is necessary to lower a corner of the target part 200a, the top screw 20 is first moved axially relative to the support tube 10 toward the side away from the base part 300a, so that the end of the top screw 20 away from the support tube 10 is axially spaced from the base part 300a, and then the second end 12 is rotated relative to the base part 300a to lower the first end 11 axially relative to the base part 300a, thereby driving the target part 200a to sink relative to the base part 300a, and then the top screw 20 is moved axially relative to the support tube 10 toward the side close to the base part 300a, so that the top screw 20 presses against the base part 300a in the axial direction.

[0062] In some embodiments, as Figure 4 As shown, the leveling assembly 100 further includes a locking member 30 (e.g., a nut), which is threadedly connected to the first end 11. A support portion 13 is protruding from the outer periphery of the support tube 10, and the target part 200a is supported by the support portion 13 and locked between the support portion 13 and the locking member 30. In this way, the first end 11 and the target part 200a can be locked or unlocked by rotating the locking member 30 relative to the first end 11. When adjusting the leveling assembly 100, the locking member 30 can be loosened first to allow the support portion 13 to rotate relative to the target part 200a, thereby facilitating the operation of operating the support tube 10 to rotate the second end 12 relative to the base member 300a, thereby facilitating adjustment. After adjustment, the locking member 30 is tightened again, thereby pressing the target part 200a between the locking member 30 and the support portion 13, so that the first end 11 is securely fixed relative to the target part 200a.

[0063] Alternatively, as Figure 4 As shown, the support portion 13 is located between the target member 200a and the base member 300a and is capable of axially supporting the target member 200a on the side closest to the base member 300a. The first end 11 partially protrudes from the side of the target member 200a away from the base member 300a. The locking member 30 is located on the side of the target member 200a away from the base member 300a to facilitate operation of the locking member 30.

[0064] In some embodiments, as Figure 4 As shown, the leveling assembly 100 further includes an elastic member 40, which elastically presses against the support portion 13 and the base member 300a to apply an elastic force to the support portion 13 axially away from the base member 300a, thereby axially tightening the support tube 10. This in turn increases the friction between the second end 12 and the base member 300a, making it difficult for the second end 12 to loosen relative to the base member 300a. Therefore, when the locking member 30 is operated to rotate relative to the first end 11, the support tube 10 is prevented from rotating relative to the base member 300a, thereby facilitating operation.

[0065] In some embodiments, as Figures 4 and 5 As shown, the elastic member 40 is a coil spring, which is sleeved outside the support tube 10 to limit the elastic member 40 through the support tube 10 and provide a guide for the axial expansion and contraction of the elastic member 40.

[0066] In some embodiments, as Figure 4 As shown, the support tube 10 is provided with a through center hole 10b in the axial direction, and the top screw 20 is threadedly connected to the center hole 10b. In this way, the top screw 20 can be operated by extending into the center hole 10b, making the operation convenient.

[0067] In some embodiments, as Figure 4As shown, a first operating hole 20b is defined on the end surface of the top screw 20 near one end of the support tube 10. The first operating hole 20b communicates with the center hole 10b. During use, a tool (such as a screwdriver) can be inserted into the first operating hole 20b to twist the top screw 20, causing it to rotate relative to the second end 12, thereby moving the top screw 20 axially relative to the second end 12. In this embodiment, the first operating hole 20b is a hexagonal hole.

[0068] In some embodiments, as Figure 4 As shown, the support tube 10 has a second operating hole 10b1 at one end away from the jackscrew 20. This second operating hole 10b1 communicates with the center hole 10b and is used to threadably adjust the relative position of the support tube 10 and the base member 300a. During use, a tool (such as a screwdriver) can be inserted into the second operating hole 10b1 and used to tighten the first end 11, thereby rotating the support tube 10 relative to the base member 300a and moving the support tube 10 axially relative to the base member 300a. In this embodiment, the second operating hole 10b1 is a hexagonal hole.

[0069] In some embodiments, as Figure 4 As shown, the base member 300a is provided with a connecting hole 300a1, which is a blind hole. The outer peripheral surface of the second end 12 of the support tube 10 is threadedly connected to the connecting hole 300a1, and the top screw 20 can be threadedly adjusted relative to the support tube 10 to abut against the bottom surface of the connecting hole 300a1, so that the top screw 20 can abut against the base member 300a along the axial direction.

[0070] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application should not depart from the spirit and scope of the technical solutions of the present application.
