[0040] The purpose of the utility model is to provide a substrate device that improves the area utilization of the substrate and makes the substrate easy to disassemble and assemble;

[0041] Another object of the present invention is to provide a 3D printing device having the above-mentioned substrate device.

[0042] like Figure 1 and Figure 2As shown, the embodiment of the present invention discloses a substrate device, comprising a substrate body 100, a support platform 200, and a locking portion 300. A mounting groove is provided on a side of the substrate body 100 facing away from the working surface, and the support platform 200 can be inserted into the mounting groove, so that the substrate body 100 is mounted and connected to the support platform 200 through the mounting groove. Furthermore, each sidewall of the mounting groove is provided with a first limiting hole, and the support platform 200 is also provided with a second limiting hole 210 corresponding to the first limiting hole. At the same time, the locking pin 310 of the locking portion 300 is slidably placed in the second limiting hole 210. After the working surface of the substrate body 100 is subjected to a preset pressure, the locking pin 310 located in the second limiting hole 210 slides, and the first end of the locking pin 310 extends into the first limiting hole. At this time, the substrate body 100 is locked and fixed on the support platform 200 through the mutual cooperation of the first limiting hole, the second limiting hole 210, and the locking pin 310, ensuring that the substrate body 100 has good stability. After the pressure on the working surface is removed, the first end of the locking pin 310 is withdrawn from the first limiting hole, that is, the limiting of the substrate body 100 is unlocked, so that the substrate body 100 can be directly removed from the support platform 200, making the substrate device provided by this embodiment easy to disassemble and assemble.

[0043] like Figure 2 、 Figure 3 and Figure 4 As shown, the locking portion 300 includes a travel slider 320 and a first limiting spring 330. A sliding groove 220 is defined on the side of the support platform 200 facing the substrate body 100, and a second limiting hole 210 extends through the sidewall of the sliding groove 220. The travel slider 320 and the sliding groove 220 are clearance-fitted, allowing the travel slider 320 to slide within the sliding groove 220. When pressure is applied to the substrate body 100, the travel slider 320, located between the support platform 200 and the substrate body 100, pushes the travel slider 320 to slide within the sliding groove 220. The travel slider 320, in turn, pushes the locking pin 310 to slide within the second limiting hole 210, causing the first end of the locking pin 310 to extend into the first limiting hole. After the pressure of the substrate body 100 is removed, the first limit spring 330 compressed between the stroke slider 320 and the sliding groove 220 has elastic potential energy. The first limit spring 330 applies a thrust to the stroke slider 320 to reset the stroke slider 320 again to ensure normal operation next time, and at the same time cancels the force of the stroke slider 320 on the locking pin 310. At this time, the end face of the stroke slider 320 is higher than the end face of the support platform 200, that is, the distance from the end face of the stroke slider 320 to the end face of the support platform 200 is the sliding distance of the stroke slider 320. When the substrate body 100 pushes the end face of the stroke slider 320 to be flush with the end face of the support platform 200, the locking pin 310 completes the limiting fixation of the substrate body 100.

[0044] like Figure 2 and Figure 6 As shown, the locking portion 300 also includes a second limiting spring 340, the second end of the locking pin 310 extends into the sliding groove 220, and the second end of the locking pin 310 is also provided with an adjustment block 311. After the second limiting spring 340 is sleeved on the locking pin 310, one end of the second limiting spring 340 abuts against the inner wall of the sliding groove 220, and the other end abuts against the adjustment block 311. After the travel slider 320 slides and applies a thrust to the locking pin 310, the locking pin 310 moves toward the first limiting hole. At this time, the second limiting spring 340 located between the adjustment block 311 and the inner wall of the sliding groove 220 is compressed and has elastic potential energy. After the travel slider 320 is reset and the force applied to the locking pin 310 is cancelled, the second limiting spring 340 with elastic potential energy applies an elastic force through the adjustment block 311, causing the locking pin 310 to move away from the first limiting hole, and then the first end of the locking pin 310 withdraws from the first limiting hole to unlock the substrate body 100 and the support table.

[0045] In a specific embodiment, the travel slider 320 is provided with a pushing protrusion 321, and the travel slider 320 pushes the movement of the locking pin 310 by abutting the pushing protrusion 321 with the adjustment block 311 at the second end of the locking pin 310, and the matching profile of the pushing protrusion 321 and the adjustment block 311 can be adjusted, such as by designing the outer profile of the adjustment block 311, the outer profile of the pushing protrusion 321, or adjusting the outer profile of the pushing protrusion 321 and the adjustment block 311 at the same time, so as to adjust the distance that the first end of the locking pin 310 extends into the first limiting hole, so as to adjust the efficiency of the locking part 300 in locking and unlocking the substrate body 100.

[0046] like Figure 6 and Figure 7As shown, the outer contours of the push protrusion 321 and the adjustment block 311 are both configured with mutually matching arcs. The continuous and smooth arcs enhance the smoothness and flexibility of the movement of the travel slider 320 in pushing the locking pin 310. Furthermore, as the travel slider 320 moves toward the bottom of the sliding groove 220, the arc of the adjustment block 311 gradually extends toward the travel slider 320, i.e., the distance between the arc of the adjustment block 311 and the travel slider 320 gradually decreases. As the travel slider 320 slides toward the bottom of the sliding groove 220, the distance that the push protrusion 321 and the adjustment block 311 contact and push the locking pin 310 into the first limiting hole gradually increases until the substrate body 100 is locked and fixed. In addition, the first end of the locking pin 310 is set to a hemispherical shape, which not only improves the smoothness of the first end of the locking pin 310 entering the first limiting hole, but also the smooth hemispherical shape can reduce the blocking force of the first end of the locking pin 310 on the substrate body 100 after unlocking, thereby ensuring the smoothness of the unlocking of the lifting and lowering movement between the substrate body 100 and the support platform 200, and facilitating the disassembly work between the substrate body 100 and the support platform 200.

[0047] like Figure 5 As shown, a spring mounting hole 221 is formed at the bottom of the sliding groove 220, and a spring sleeve 322 is provided on the travel slider 320. Thus, the first limit spring 330 is placed in the spring mounting hole 221. At the same time, the spring sleeve 322 is sleeved on the outside of the first limit spring 330, thereby ensuring the stability of the first limit spring 330 after installation. The spring sleeve 322 of the travel slider 320 is integrally connected to the pushing protrusion 321, and there is a clearance fit between the spring sleeve 322 and the spring mounting hole 221, allowing the spring sleeve 322 to slide within the spring mounting hole 221. A sliding gap is left between the spring sleeve 322 and the bottom of the spring mounting hole 221, thereby ensuring the sliding of the travel slider 320 in the sliding groove 220, so that the travel slider 320 pushes the movement of the locking pin 310.

[0048] like Figure 2As shown, the locking portion 300 is provided with a connecting bolt 350 to mount the travel slider 320 on the support platform 200. Specifically, a through hole is provided in the travel slider 320, which passes through the pushing protrusion 321 and the spring sleeve 322 in sequence, and a connecting threaded hole 222 is provided at the bottom of the sliding groove 220 to be threadedly engaged with the connecting bolt 350. The center of the connecting threaded hole 222 is located on the same axis as the center of the spring mounting hole 221. Therefore, the connecting bolt 350 passes through the travel slider 320 and the first limit spring 330 in sequence through the through hole and is connected to the connecting threaded hole 222. At the same time, the travel slider 320 can slide along the extension direction of the connecting bolt 350 to ensure that the travel slider 320 pushes the locking pin 310. In addition, a countersunk hole is provided in the travel slider 320 so that the nut of the connecting bolt 350 after installation is located in the countersunk hole. This design is concealed to avoid the connection bolt 350 from affecting the interaction process between the travel slider 320 and the substrate body 100. The connecting bolt 350 not only serves to install the travel slider 320, but also the nut of the connecting bolt 350 serves to limit the travel slider 320 during the sliding process of the travel slider 320, so that the travel slider 320 can be reset to a preset position when pushed by the first limit spring 330.

[0049] like Figure 2 As shown, the center of the stroke slider 320, the center of the through hole, the center of the spring mounting hole 221 and the center of the connecting threaded hole 222 are all located on the center line of the support platform 200, so that the stroke slider 320, the first limit spring 330, and the connecting bolt 350 are arranged in the center of the support platform 200, thereby improving the uniformity of force between the stroke slider 320 and the substrate body 100. When the working surface of the substrate body 100 is subjected to external force, the substrate body 100 can better promote the sliding of the stroke slider 320, thereby improving the sensitivity and reliability of operation. Furthermore, multiple first limiting holes are symmetrically arranged with the center of the substrate body 100 as the symmetry center. For example, a first limiting hole is provided on each of the four side walls of the placement groove in the substrate body 100 provided in this embodiment, and the first limiting holes on the corresponding two side walls are symmetrically arranged with the center of the substrate body 100. At the same time, the second limiting holes 210 corresponding to the first limiting holes are symmetrically arranged on the four side walls of the sliding groove 220. The uniform distribution of the first limiting holes and the second limiting holes 210 improves the stability and stability of the locking and fixing of the substrate body 100 and the support platform 200.

[0050] The present invention also discloses a 3D printing device including a substrate device. Since the 3D printing device includes the substrate device, it has all the technical effects of the substrate device, which will not be described in detail herein.

[0051] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
