[0046] In the related art, the display device is usually fixedly arranged on the machine body and protrudes from the machine body, which causes inconvenience in setting protection measures for the display device during logistics transportation, and the display device is easily bumped or damaged during the logistics transportation, greatly affecting the user's use experience and the service life of the machine.

[0047] Based on the above problems and ideas, please refer to Figures 1 to 10The utility model provides a kind of 3D printer, 3D printer includes display device 1 and fuselage 2, display device 1 is equipped with limiting piece 11 and locking piece 12;Fuselage 2 is equipped with limiting groove 22 and locking groove 21, limiting piece 11 and limiting groove 22 are along the first direction plug-in fit, locking groove 21 is along the first direction and is set, locking protrusion 211 is equipped in locking groove 21, the both sides of locking protrusion 211 are equipped with unlocking space 212 and locking space 213;

[0048] Wherein, display device 1 has with the locking state of locking of fuselage 2 and the unlocking state of unlocking of fuselage 2;In locking state, locking piece 12 is located in locking space 213, locking protrusion 211 cooperates with the groove wall of locking groove 21 in the first direction and limits locking piece 12, limiting piece 11 is inserted into limiting groove 22;In unlocking state, locking piece 12 is located in unlocking space 212, limiting piece 11 is suitable for pulling out from limiting groove 22.

[0049] In the embodiment, as Figures 1 to 5 As shown, by the plug-in fit of limiting piece 11 and limiting groove 22 and the locking fit of locking piece 12 and locking groove 21, display device 1 realizes the detachable connection with fuselage 2, when logistics transportation, display device 1 can be detached from fuselage 2, and is fully protected, to avoid display device 1 from being damaged when transporting;Meanwhile, the assembly structure of display device 1 and fuselage 2 is simple, easy to assemble, when using, user can easily and quickly assemble display device 1 and fuselage 2.

[0050] It can be understood that, in the embodiment, limiting piece 11 and limiting groove 22 are along the first direction plug-in fit, when limiting piece 11 is inserted into limiting groove 22, limiting piece 11 and the groove wall of limiting groove 22 abut limiting, only in the first direction has freedom degree.And locking groove 21 is along the first direction and is provided with unlocking space 212 and locking space 213, since the position of locking piece 12 and limiting piece 11 on display device 1 is relatively fixed, locking piece 12 is inserted into limiting groove 22 by the slot of locking groove 21, actually, only can also move along the first direction, therefore, after limiting piece 11 is inserted into limiting groove 22 along the first direction, locking piece 12 also enters locking space 213 from unlocking space 212 along the first direction, under the limiting fit of locking protrusion 211 and locking groove 21, locking piece 12 cannot move freely along the first direction, limiting piece 11 is also limited in limiting groove 22, cannot move along the first direction.So display device 1 is in the locking state of locking with fuselage 2, cannot move relative to fuselage 2 in the state of unlocking, further avoid display device 1 from appearing to shake or fall off when using 3D printer, improve the installation stability of display device 1.

[0051] The display device 1 also has an unlocked state in which the body 2 is unlocked, in the unlocked state, the locking piece 12 is located in the unlocking space 212 of the locking slot 21, at this time, the limiting piece 11 can be freely moved along the first direction, and the limiting piece 11 and the locking piece 12 can be taken out from the limiting slot 22 and the locking slot 21, and the display device 1 can be disassembled.

[0052] In actual implementation, in the process that the locking piece 12 enters the locking space 213 from the unlocking space 212 along the first direction, the locking piece 12 is elastically deformed by being pressed by the locking protrusion 211, so as to bypass the locking protrusion 211, and after entering the locking space 213, the locking piece 12 restores the original shape due to the loss of the pressure of the locking protrusion 211, the locking piece 12 is clamped into the locking space 213 and is limited by the locking protrusion 211, so that the display device 1 enters the locked state. Correspondingly, in the process that the locking piece 12 is pushed into the unlocking space 212 from the locking space 213 along the first direction, the locking piece 12 is also elastically deformed by being pressed by the locking protrusion 211, so as to bypass the locking protrusion 211 and enter the unlocking space 212, so that the display device 1 enters the unlocked state. It can be understood that the locking piece 12 will be subjected to a certain resistance in the process of bypassing the locking protrusion 211, therefore, a certain external force needs to be applied to the locking piece 12 to overcome the resistance, so as to realize the unlocking of the display device 1, and thus the stability of the display device 1 installed on the body 2 can be ensured.

[0053] In an embodiment of the present application, as shown in Figures 4 to 5 The body 2 is provided with a mounting surface 23, the locking slot 21 penetrates through the mounting surface 23 and forms a first opening 214, the first opening 214 is arranged along the first direction and is in communication with the unlocking space 212 and the locking space 213.

[0054] In the embodiment, the first opening 214 is in communication with the unlocking space 212 and the locking space 213 at the same time, when the locking piece 12 moves between the unlocking space 212 and the locking space 213, the first opening 214 plays a role of avoiding the locking piece 12 to avoid that the edge of the first opening 214 blocks the movement of the locking piece 12.

[0055] In the process of installing the display device 1, the locking piece 12 extends into the unlocking space 212 from the first opening 214 along the second direction, wherein the second direction can be perpendicular to the plane in which the mounting surface 23 is arranged. The locking process of the display device 1 is that the locking piece 12 extends into the unlocking space 212 along the second direction and then is clamped into the locking space 213 along the first direction. Alternatively, the locking piece 12 is arranged along the second direction and is in the form of a rod or a stick.

[0056] Optionally, the limiting groove 22 also extends along the first direction, and the slot of the limiting groove 22 is arranged at the end of the limiting groove 22, and correspondingly, the limiting member 11 also extends along the first direction, so as to be inserted into the limiting groove 22 along the first direction.

[0057] Since the limiting member 11 and the locking member 12 are relatively fixed on the display device 1, when the locking member 12 extends into the unlocking space 212 along the second direction, the limiting member 11 should also move along the second direction and be aligned with the slot of the limiting groove 22; when the locking member 12 moves to the locking space 213 along the first direction, the limiting member 11 is inserted into the limiting groove 22 along the first direction. In the embodiment, the plane of the slot of the limiting groove 22 is arranged in parallel with the second direction, so as to align the slot of the limiting groove 22 when the limiting member 11 moves along the second direction. Specifically, when the slot of the mounting groove is arranged at the end of the mounting groove, a protrusion or a clearance recess can be arranged on the mounting surface 23, and the plane of the side wall of the protrusion or the plane of the side wall of the clearance recess is parallel with the second direction, and the slot of the limiting groove 22 is arranged on the side wall of the protrusion or the clearance recess, so that the plane of the slot of the mounting groove is arranged in parallel with the second direction.

[0058] Further, the first opening 214 is actually the slot of the locking groove 21, and the first opening 214 in the embodiment is arranged at the side of the locking groove 21.

[0059] In another embodiment of the utility model, the locking groove 21 penetrates through the mounting surface 23 and forms the first opening 214, the first opening 214 is arranged at the end of the locking groove 21 and only directly communicates with the unlocking space 212, the first direction is arranged at an angle with the plane of the mounting surface 23, and the second direction is actually arranged in parallel with the first direction. In the process of mounting the display device 1, the locking member 12 extends into the unlocking space 212 along the first direction from the first opening 214, and then continues to enter the locking space 213 from the unlocking space 212 along the first direction, and the locking is completed. In the embodiment, the limiting groove 22 also extends along the first direction, and when the locking member 12 extends into the unlocking space 212 along the first direction, the limiting member 11 also extends into the limiting groove 22 along the first direction and abuts against the side wall of the limiting groove 22 for limiting, and when the locking member 12 is clamped into the locking space 213, the limiting member 11 is also limited in the limiting groove 22. Optionally, the first direction is arranged perpendicular to the plane of the mounting surface 23, and the limiting member 11 and the mounting member are arranged in a columnar or rod shape along the first direction.

[0060] In an embodiment of the utility model, as shown in Figure 4 and Figure 10 The locking member 12 and / or the locking protrusion 211 are provided with a guide inclined surface 121 for guiding the locking member 12 to enter the locking space 213 from the unlocking space 212.

[0061] In the embodiment, the guide slope 121 can reduce the resistance of the locking member 12 to enter the locking space 213 from the unlocking space 212 in the first direction, so as to reduce the difficulty of the locking member 12 to be clamped into the locking space 213, and facilitate the user to install the display device 1 on the fuselage 2.

[0062] In actual implementation, the guide slope 121 can be arranged on the locking member 12 only, or on the locking protrusion 211 only, or on both the locking member 12 and the locking protrusion 211, which is not limited here. When the guide slope 121 is arranged on the locking member 12, the guide slope 121 is arranged to be inclined away from the locking protrusion 211 in the direction from the unlocking space 212 to the locking space 213, based on the position where the locking member 12 and the guide slope 121 abut against each other. When the guide slope 121 is arranged on the locking protrusion, the guide slope 121 is arranged to be inclined close to the locking member 12 in the direction from the unlocking space 212 to the locking space 213, based on the position where the locking member 12 and the guide slope 121 abut against each other.

[0063] It can be understood that when the guide slope 121 is arranged on both the locking member 12 and the locking protrusion 211, the guide slope 121 on the locking member 12 and the guide slope 121 on the locking protrusion 211 are arranged to be parallel, so as to achieve a better guiding effect.

[0064] Optionally, the cross section of the locking protrusion 211 in the first direction is approximately a right-angled triangle, the hypotenuse of the triangle faces the unlocking space 212, and the right angle of the triangle faces the locking space 213, wherein the hypotenuse corresponds to the projection of the guide slope 121 on the cross section. In this way, only the resistance of the locking member 12 to be clamped into the locking space 213 is reduced, and the resistance of the locking member 12 to enter the unlocking space 212 from the locking space 213 is not reduced, so as to facilitate the user to install the display device 1, and also ensure the stability of the display device 1 installed on the fuselage 2. When the locking member 12 is moved from the locking space 213 to the unlocking space 212, the user can manually lift the locking member 12 away from one end of the locking protrusion 211 to avoid the locking protrusion 211, and then move the locking member 12 to the unlocking space 212 in the first direction, so that the display device 1 enters the unlocking state.

[0065] Optionally, the cross section of the locking member 12 in the first direction can be approximately a right-angled triangle or a right-angled trapezoid, wherein the inclined surface of the right-angled triangle or the right-angled trapezoid corresponds to the projection of the guide slope 121 on the cross section.

[0066] In an embodiment of the utility model, as shown in Figure 10 the locking member 12 is provided with a guide slope 121, and the groove wall of the locking space 213 is provided with an abutting surface parallel to the guide slope 121; in the locking state, the locking member 12 is located in the locking space 213, and the guide slope 121 abuts against the abutting surface.

[0067] It can be understood that, since the locking member 12 is provided with the guide slope 121, in order to improve the stability of the locking member 12 being limited in the locking space 213, the groove wall of the locking space 213 facing the guide slope 121 is arranged in parallel with the guide slope 121, that is, the abutting surface in the embodiment, and when the locking member 12 is located in the locking space 213, the guide slope 121 abuts against the abutting surface.

[0068] In an embodiment of the present application, as shown in Figures 4 to 10 The limiting member 11 includes an included angle arranged extending portion 111 and a limiting portion 112, the extending portion 111 is connected to the display device 1, the limiting portion 112 is connected to one end of the extending portion 111 away from the display device 1, the limiting groove 22 includes a first groove body 221 and a second groove body 222 in communication, the first groove body 221 is arranged through the mounting surface 23 and forms a second opening 223; in the locked state, the extending portion 111 extends into the second opening 223, and the limiting portion 112 is inserted into the second groove body 222; in the unlocked state, the extending portion 111 extends into the second opening 223, and the limiting portion 112 is located in the first groove body 221.

[0069] In the embodiment, the second opening 223 is arranged on the mounting surface 23 and is arranged in communication with the first groove body 221 only. When installing the display device 1, the limiting portion 112 of the limiting member 11 is aligned with the second opening 223 and extends into the first groove body 221 along the second direction, and correspondingly, the locking member 12 also extends into the unlocking space 212 of the locking groove 21 along the second direction, at this time, the display device 1 is in the unlocked state, and the limiting member 11 and the locking member 12 can be taken out from the limiting groove 22 and the unlocking groove; then the limiting member 11 is moved along the first direction to make the limiting portion 112 inserted into the second groove body 222 and abut against the groove wall of the second groove body 222 for limiting, and correspondingly, the locking member 12 also enters the locking space 213 along the first direction, so that the locking of the display device 1 is completed. When the limiting member 11 moves along the first direction, the extending portion 111 also moves along the first direction, and the second opening 223 plays a role of avoiding the second direction.

[0070] It can be understood that the second opening 223 in the present application is actually a slot of the limiting groove 22 and is located at the side of the limiting groove 22.

[0071] Alternatively, the extending portion 111 and the limiting portion 112 can be arranged perpendicularly, that is, the limiting member 11 is arranged in an L shape, the second direction is arranged perpendicularly to the plane where the mounting surface 23 is located, the first direction is arranged in parallel to the plane where the mounting surface 23 is located, and the second opening 223, the first groove body 221 and the second groove body 222 are all arranged along the first direction.
