[0049] In order to make the purpose, technical solutions and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0050] In the description of this application, the meaning of "plurality" is at least two, for example, two, three, etc., unless otherwise specifically defined. All directional indications in the embodiments of this application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement of the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0051] To provide a more detailed and complete description of the present disclosure, the following provides illustrative descriptions of the embodiments and examples of the present application; however, these descriptions are not intended to be the only ways to implement or use the embodiments of the present application. The embodiments cover features of various embodiments, as well as the method steps and sequences for constructing and operating these embodiments. However, other embodiments may also be used to achieve the same or equivalent functionality and step sequences.

[0052] Please refer to Figures 1-16 The embodiment of the present application provides a rotating structure and a three-dimensional printing device, which can adjust the tilt angle of the display screen according to needs during use, and store the display screen during transportation or handling, effectively avoiding damage to the display screen. Please refer to Figure 1 , which is a structural schematic diagram of a rotating structure provided in an embodiment of the present application, wherein the rotating structure includes a first connecting member 10 and a second connecting member 20 plugged into the first connecting member 10.

[0053] As an optional embodiment, the first connector 10 and the second connector 20 are connected in a plug-in manner. Figure 3 and Figure 5 ,in Figure 3 This is a structural diagram of the insertion channel 12 in the rotating structure provided in an embodiment of the present application. Figure 5The structural schematic diagram of the connector 11 in the rotating structure provided in the embodiment of the present application shows that the present application provides a connector 11 between the first connector 10 and the second connector 20, and a plug-in channel 12 is provided on the side of the first connector 10 close to the second connector 20. The connector 11 is arranged inside the plug-in channel 12. At this time, one end of the connector 11 elastically abuts against the plug-in channel 12, and the other end of the connector 11 extends from the plug-in channel 12 through the plug-in through hole 13 to the first connector 10.

[0054] Specifically, a first protrusion 111 is provided at the other end of the connector 11. In the embodiment of the present application, the end provided with the first protrusion 111 is arranged close to the plug-in hole 13. By arranging the above-mentioned plug-in hole 13 at positions corresponding to the first protrusion 111 on the first connector 10 and the second connector 20, the first protrusion 111 can pass through the plug-in hole 13.

[0055] It should be noted that when actually opening the plug-in hole 13, the diameter of the plug-in hole 13 should be avoided from being too large so that the connector 11 falls off the plug-in hole 13. It is necessary to ensure that only the first protrusion 111 can move in the plug-in hole 13 during the rotation of the connector 11.

[0056] Since the connector 11 elastically abuts against the plug channel 12 set inside the first connector 10, the first protrusion 111 will move relative to the plug hole 13 under the action of external force, so that the connector 11 will move in the plug channel 12 in a direction away from or close to the plug hole 13.

[0057] Taking the application of the above-mentioned rotating structure to a three-dimensional printing device as an example, since the printer needs to be controlled through the display screen 30 or the printing status needs to be known in real time through the display screen 30 during the 3D printing process, it is usually necessary to equip the building platform 40 with a corresponding display screen 30 for use. In the related art, the display screen 30 is usually directly fixed on the building platform 40. This method cannot adjust the angle of the display screen 30, which affects the user experience to a certain extent.

[0058] In the examples of this application, please refer to Figure 11, which is a structural schematic diagram of the movable groove 421 in the three-dimensional printing device provided by an embodiment of the present application. The above-mentioned first connecting member 10 and the second connecting member 20 can be relatively arranged on both sides of the building platform 40. The present application provides a connecting hole 42 on the side wall of the building platform 40 that is adapted to the outer wall of the above-mentioned first connecting member 10. At this time, the side of the first connecting member 10 close to the second connecting member 20 is arranged in the connecting hole 42, and the side of the first connecting member 10 away from the second connecting member 20 is arranged outside the building platform 40. The second connecting member 20 is arranged inside the building platform 40 and plugged into the first connecting member 10.

[0059] Furthermore, the present application provides a plurality of wavy movable grooves 421 distributed along the circumferential direction on the connecting hole 42, and the first protrusion 111 of the plug-in connector 11 is passed through the plug-in hole 13 and abuts against the corresponding movable groove 421. Since the plug-in connector 11 elastically abuts against the plug-in channel 12 provided inside the first connector 10, the first protrusion 111 will shrink inward or move outward relative to the plug-in hole 13 under the action of the movable groove 421 during the rotation process.

[0060] As an optional implementation, please refer to Figure 2 , which is a three-dimensional assembly diagram of the rotating structure provided in an embodiment of the present application. In the present application, a first rotating shaft 14 for rotatingly connecting the display screen 30 is provided on the side of the first connecting member 10 away from the second connecting member 20. The display screen 30 is provided through the first rotating shaft 14 so that the display screen 30 can rotate relative to the first connecting member 10, and then the plug-in member 11 provided in the first connecting member 10 is matched with the movable groove 421, so that the first connecting member 10 and the second connecting member are rotated relative to the building platform 40, thereby realizing the adjustment of the position of the display screen 30, making it convenient for the user to adjust the display screen 30 to the desired position and tilt angle, thereby improving the user experience.

[0061] For details, please refer to Figure 5 The plug-in channel 12 provided in the present application includes two first baffles 121 arranged opposite to each other and a second baffle 122 for connecting the two first baffles 121. It can be observed that the two first baffles 121 are arranged on both sides of the plug-in hole 13 and together with the second baffle 122 form the plug-in channel 12, which restricts the connector 11 in the plug-in channel 12 so that only the first protrusion 111 in the connector 11 passes through the plug-in hole 13.

[0062] In the embodiment of the present application, a second protrusion 112 is provided at one end of the above-mentioned connector 11 away from the plug-in hole 13, and a first spring 113 is provided on the outer wall sleeve of the second protrusion 112. The elastic abutment between the connector 11 and the plug-in channel 12 is achieved by abutting the other end of the first spring 113 with the second baffle 122.

[0063] In this way, since the second protrusion 112 and the second baffle 122 are elastically connected by the first spring 113, during the rotation of the above-mentioned rotating structure, the first protrusion 111 will move toward or away from the second baffle 122 under the action of the movable groove 421, and the second protrusion 112 will compress or rebound the first spring 113 on the first protrusion 111, so that the rotated first protrusion 111 will again abut against the corresponding movable groove 421, waiting for the next rotation action.

[0064] As an optional implementation, please refer to Figure 4 , which is a structural schematic diagram of the first connecting member 10 in the rotating structure provided in an embodiment of the present application. In order to achieve a snap-on connection between the first connecting member 10 and the second connecting member 20, the present application is provided with a first limiting step 15 extending in the direction of the first connecting member 10 close to the second connecting member 20. It can be observed that the first limiting step 15 protrudes from the plane where the first connecting member 10 is located.

[0065] Please refer to Figure 6 , which is a structural schematic diagram of the second connecting member 20 in the rotating structure provided in an embodiment of the present application. The present application provides a first docking groove 21 adapted to the first limiting step 15 at the position of the second connecting member 20 corresponding to the first limiting step 15, so that the second connecting member 20 can be inserted into the first connecting member 10 by snapping the first limiting step 15 into the first docking groove 21.

[0066] Furthermore, in order to improve the processing accuracy of the above-mentioned rotating structure and prevent the first connecting member 10 and the second connecting member 20 from falling off or shaking significantly during the rotation process, the present application provides a first arc-shaped groove 151 in the inward groove of the outer wall of the first limiting step 15, and a first docking protrusion adapted to the first arc-shaped groove 151 is provided at the position of the second connecting member 20 corresponding to the first arc-shaped groove 151. When the second connecting member 20 is inserted into the first connecting member 10, the first arc-shaped protrusion 211 passes through the first arc-shaped groove 151.

[0067] Specifically, it is preferred to set the position of the first arc-shaped protrusion 211 close to the first connecting member 10, so that when the first limiting step 15 is passed through the corresponding first docking groove 21, the first arc-shaped protrusion 211 set close to the first connecting member 10 will naturally be engaged with the first arc-shaped slot set on the outer wall of the first limiting step 15, effectively improving the connection strength and connection accuracy between the first connecting member 10 and the second connecting member 20.

[0068] In an optional embodiment, the number of the above-mentioned first limiting steps 15, the first docking groove 21, the first arc-shaped groove 151 and the first arc-shaped protrusion 211 is at least two, preferably set to two, and the two first limiting steps 15, the first docking groove 21, the first arc-shaped groove 151 and the first arc-shaped protrusion 211 can be respectively arranged on both sides of the connector 11 along the circumferential direction; of course, the number of the above-mentioned first limiting steps 15, the first docking groove 21, the first arc-shaped groove 151 and the first arc-shaped protrusion 211 can also be adjusted according to actual needs. In principle, the first limiting step 15, the first docking groove 21, the first arc-shaped groove 151 and the first arc-shaped protrusion 211 must be set at the same time and satisfy the matching relationship with each other.

[0069] Please continue to refer to Figure 4 In this application, a mounting portion 16 is provided on a side of the first connecting member 10 away from the second connecting member 20, and a rotatable connection between the rotating structure and the display screen 30 is achieved through the mounting portion 16 and the first rotating shaft 14 provided through the mounting portion 16.

[0070] For details, please refer to Figure 3 The above-mentioned first rotating shaft 14 includes a first end 141 and a second end 142. In the present application, the first end 141 of the first rotating shaft 14 can be rotatably connected to the mounting portion 16, for example, by means of threaded screw holes, and the second end 142 of the first rotating shaft 14 is elastically connected to the mounting portion 16. For example, a second spring 143 can be sleeved on the second end 142 of the first rotating shaft 14, so that the other end of the second spring 143 is elastically connected to the mounting portion 16. In this way, the first end 141 of the first rotating shaft 14 is rotatably connected to the mounting portion 16, and the second end 142 of the first rotating shaft 14 is elastically connected to the mounting portion 16.

[0071] As an optional embodiment, the present application provides a first limiting strip 161 that protrudes upward on one side of the mounting portion 16 corresponding to the first end 141 of the first rotating shaft 14 .

[0072] Further, please refer to Figure 7 , which is a structural schematic diagram of the display screen 30 in the rotating structure provided in an embodiment of the present application. In the present application, a connecting portion 31 is extended on one side of the display screen 30 close to the first connecting member 10. It can be observed that an axial hole 311 for the first rotating shaft 14 to pass through is provided on the connecting portion 31. In actual application, the first rotating shaft 14 needs to pass through the axial hole 311 on the connecting portion 31 for setting.

[0073] Furthermore, a first limiting groove 312 adapted to the first limiting bar 161 is provided on one side of the mounting portion 16 close to the first end 141 of the first rotating shaft 14. When the first rotating shaft 14 is set through the connecting portion 31, the first limiting groove 312 provided at the bottom of the connecting portion 31 will abut against the first limiting bar 161 provided on the mounting portion 16, and the rotation of the display screen 30 is limited by the matching relationship between the first limiting groove 312 and the first limiting bar 161.

[0074] In the embodiment of the present application, the number of the above-mentioned first limiting grooves 312 is at least two. Taking the example of at least two first limiting grooves 312 being provided at the bottom of the connecting portion 31, the two first limiting grooves 312 are vertically arranged and intersect at the shaft hole 311. Through this arrangement, the rotation angle of the display screen 30 relative to the mounting portion 16 can be limited to 90 degrees. Of course, three first limiting grooves 312 can also be provided at the bottom of the connecting portion 31. At this time, the three first limiting grooves 312 are arranged at 60 degrees apart from each other and intersect at the shaft hole 311, so that the rotation angle of the display screen 30 relative to the mounting portion 16 will be limited to 60 degrees.

[0075] For details, please refer to Figure 7 , taking the example of two first limiting grooves 312 being arranged vertically and intersecting the shaft hole 311 for explanation, since the first end 141 of the first rotating shaft 14 is rotationally connected to the mounting portion 16, and the second end 142 of the first mounting portion 16 is elastically connected to the mounting portion 16, during the rotation of the display screen 30, the display screen 30 will squeeze the second spring 143 arranged on the top upward. At this time, the first limiting groove 312 arranged at the bottom of the connecting portion 31 will fall off the first limiting bar 161 arranged on the mounting portion 16. Since two first limiting grooves 312 perpendicular to each other are arranged at the bottom of the connecting portion 31, the rotation angle of the display screen 30 will be limited to 90 degrees.

[0076] After the display screen 30 is rotated to a preset angle such as 90 degrees as mentioned above, under the action of the elastic force of the second spring 143, the first limiting groove 312 at the bottom of the connecting part 31 after rotation will also abut against the first limiting bar 161 set on the mounting part 16, waiting for the next rotation action of the display screen 30.

[0077] Furthermore, the present application provides at least two specific implementations of the mounting portion 16 .

[0078] Please continue to refer to Figure 4In this specific embodiment, the above-mentioned mounting portion 16 includes an annular baffle 162 arranged on the outer side wall of the first connecting member 10. It can be observed that a rotation groove 163 for the display screen 30 to rotate is provided on the annular baffle 162. At this time, the first rotating shaft 14 sequentially passes through the top and top of the annular baffle 162, and when the display screen 30 rotates to the side close to the first connecting member 10, the display screen 30 abuts against the side wall of the first connecting member 10. The first connecting member 10 can also effectively limit the rotation angle of the display screen 30 relative to the first connecting member 10.

[0079] Similarly, the first end 141 of the first rotating shaft 14 is rotationally connected to the annular baffle 162, and the other end of the first rotating shaft 14 is elastically connected to the annular baffle 162 through the second spring 143. It can be observed that the first rotating shaft 14 is set through the top and bottom of the annular baffle 162, and the present application provides a first limit bar 161 that protrudes upward at the bottom of the annular baffle 162.

[0080] Please refer to Figures 8-10 ,in, Figures 8-10 The first, second, and third application examples of the rotating structure provided in the embodiment of the present application are shown respectively, and Figures 8-10 For application Figure 4 The application embodiment diagram of the mounting portion 16 structure shown in FIG. Figure 8 In the embodiment, the display screen 30 is tilted relative to the first plane 41 of the building platform 40. The display screen 30 can be rotated by the above-mentioned rotating structure provided in the embodiment of the present application. Figure 9 , it can be observed that the display screen 30 rotates to the side wall of the building platform 40 and is perpendicular to the first plane 41. At this time, the other end of the display screen 30 is away from the side wall of the rotating platform 40. Figure 10 , the display screen 30 is rotated through the first rotating shaft 14 so that the display screen 30 is in contact with the side wall of the building platform 40 and is perpendicular to the first plane 41, so that the inclined display screen 30 is gradually stored in the side wall of the building platform 40; as for how to rotate the display screen 30 from the side wall of the building platform 40 to be inclined relative to the first plane 41, this application will not go into details here.

[0081] Please refer to Figure 13 , is a structural schematic diagram of the adapter seat 164 in the rotating structure provided in an embodiment of the present application. In another specific embodiment provided in the present application, the mounting portion 16 includes a adapter seat 164 connected to the outer wall of the first connecting member 10. The adapter seat 164 is preferably extended in a direction away from the plug-in connector 11. It can also be understood that, with the direction of the second connecting member 20 toward the first connecting member 10 as the first direction, the adapter seat 164 is extended in a direction perpendicular to the first direction.

[0082] Further, please refer to Figure 14 , which is a structural schematic diagram of the first limit plate 167 in the rotating structure provided in an embodiment of the present application. It can be observed that the longitudinal section of the adapter seat 164 is whistle-shaped and the interior is hollow. The internal hollow structure is used to pass the wire 32 of the display screen 30. The present application provides a first mounting plate 165 and a second mounting plate 166 at the end of the adapter seat 164 away from the connector 11, so that the second mounting plate 166 is flush with the end of the adapter seat 164, and the first rotating shaft 14 is passed through the first mounting plate 165 and the second mounting plate 166. At this time, the first end 141 of the first rotating shaft 14 is rotatably connected to the first mounting plate 165, and the second end 142 of the first rotating shaft 14 is elastically connected to the second mounting plate 166 through the second spring 143, and a first limit bar 161 is also provided on the side of the first mounting plate 165 close to the second mounting plate 166, which protrudes upward.

[0083] It can be understood that the distance between the first mounting plate 165 and the second mounting plate 166 should be greater than the length of the connecting portion 31 of the display screen 30. When connecting the display screen 30 to the above-mentioned adapter 164, the first rotating shaft 14 passes through the connecting portion 31 of the display screen 30, and the display screen 30 is rotated and connected between the first mounting plate 165 and the second mounting plate 166 through the first rotating shaft 14, so as to realize the rotation of the display screen 30 relative to the adapter 164.

[0084] Preferably, a first limit plate 167 can be connected to the side of the first mounting plate 165 and the second mounting plate 166 away from the first rotating shaft 14. When the display screen 30 is rotated to be close to the building platform 40, the display screen 30 will abut against the first limit plate 167, so that the rotation angle of the display screen 30 can be effectively limited by the first limit plate 167.

[0087] It can be observed that in this embodiment, by setting the mounting portion 16 as an adapter seat 164 with a whistle-shaped longitudinal section, the display screen 30 can be rotated to above the first plane 41. The above two settings of the mounting portion 16 are both feasible and can be selected according to actual needs, which should be known to those skilled in the art.

[0088] As an optional embodiment, the present application provides wire holes 17 for the wires 32 to pass through on the connecting part 31, the first connecting part 10 and the second connecting part 20, so that the wires 32 in the display screen 30 can be connected to the building platform 40 through the connecting part 31, the mounting part 16, the first connecting part 10 and the second connecting part 20.

The present application rotates one end of the rotating structure to the building platform 40 and rotates the other end of the rotating structure to the display screen 30, thereby realizing the position movement of the display screen 30 relative to the building platform 40 through the rotating structure.

[0090] In the embodiment of the present application, the display screen 30 can be moved from the first position to the third position via the second position, or the display screen 30 can be moved from the third position to the first position via the second position through the above-mentioned rotating structure.

[0091] Among them, when the display screen 30 is in the first position, the display screen 30 is inclined relative to the first plane 41 where the building platform 40 is located; when the display screen 30 is in the second position, the display screen 30 is arranged on the side of the building platform 40 and is perpendicular to the first plane 41; when the display screen 30 is in the third position, the display screen 30 is in contact with the side of the building platform 40 and is perpendicular to the first plane 41.

The display screen 30 is arranged on the side of the building platform 40 and is in contact with the side wall of the building platform 40 and is perpendicular to the first plane 41. The present application can move the display screen 30 from the first position to the third position via the second position through the above-mentioned rotating structure, or move the display screen 30 from the third position to the first position via the second position, thereby improving the user experience during the printing process.

[0093] As an optional implementation, please continue to refer to Figure 11 In this application, a connection hole 42 is opened on the side wall of the building platform 40, which is compatible with the outer wall of the first connecting member 10. By setting the first connecting member 10 in the connection hole 42 and setting the second connecting member 20 inside the building platform 40, the second connecting member 20 is inserted into the first connecting member 10.

[0094] Furthermore, the present application provides a plurality of wavy movable grooves 421 distributed along the circumferential direction on the connecting hole 42, so that the first protrusion 111 of the connector 11 abuts against the movable groove 421, and the display screen 30 is installed on the mounting portion 16 of the first connector 10. The display screen 30 can be rotated so that the display screen 30 is in contact with and away from the side wall of the building platform 40, and the first connector 10 and the second connector 20 can be rotated so that the first protrusion 111 of the connector 11 is moved in the movable groove 421, thereby adjusting the inclination of the display screen 30 relative to the first plane 41.

[0095] Please refer to Figure 12 , which is a structural schematic diagram of the limiting protrusion 43 in the three-dimensional printing device provided in an embodiment of the present application. It can be observed that the present application provides a second arc-shaped groove 22 on the inner groove of the outer wall of the second connecting member 20, and a limiting protrusion 43 is provided on the inner wall of the building platform 40. The limiting protrusion 43 is arranged close to the second arc-shaped groove 22 and is clamped in the second arc-shaped groove 22, thereby limiting the rotation angle of the display screen 30 to a preset angle.

[0096] Furthermore, the number of the first limiting grooves 312 can be set to two, so that the two first limiting grooves 312 are set vertically and intersect with the axial hole 311, thereby limiting the rotation angle of the display screen 30 relative to the side wall of the building platform 40 to 90 degrees, and then by setting the central angle corresponding to a number of circumferentially distributed wavy movable grooves 421 to 60 degrees, the inclination angle of the display screen 30 relative to the first plane 41 is limited to 0-60 degrees; of course, the angle of the above-mentioned display screen 30 relative to the side wall of the building platform 40 and the inclination angle of the display screen 30 relative to the first plane 41 can also be adaptively adjusted.
