DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model protection.

[0027] In the description of the utility model, it is understood that the terms "hole", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.

[0028] Please refer to Figures 1-6The utility model discloses a folding 3D printing equipment convenient to store, including base 1, the top rotation of base 1 is installed with printing support 2, the symmetry of base 1 is welded with hinged frame 3, two hinged frame 3 all are set up with two perforations 4, the side of printing support 2 close to two perforations 4 all are set up with jack 5, the side of printing support 2 and located the jack 5 is set up with the limiting hole 6, the perforation 4 and jack 5 are inserted with elastic plug-in component 7, elastic plug-in component 7 can be inserted in limiting hole 6, the middle of both ends of printing support 2 all are set up with long groove 8, the first magnetic piece 9 is located in long groove 8, the both ends of base 1 are symmetrically equipped with limiting mechanism 10, limiting mechanism 10 is fixedly installed with second magnetic piece 11, limiting mechanism 10 can be located in long groove 8, and the first magnetic piece 9 and second magnetic piece 11 can be mutually adsorbed.

[0029] Two perforations 4 are 90 ° between, and the edge of two perforations 4 is inverted bevel angle, the edge of limiting hole 6 close to the side of perforation 4 is inverted bevel angle.

[0030] In the normal use state of equipment, printing support 2 keeps perpendicular with base 1, at this time, the jack 5 on printing support 2 corresponds with the higher position of one perforation 4 on hinged frame 3, and elastic plug-in component 7 is inserted into perforation 4 and jack 5, because of its internal elastic structure, part of components will protrude into limiting hole 6 due to its own elastic effect, as long as there is no external force forcibly pulling between limiting hole 6 and elastic plug-in component 7, elastic plug-in component 7 will be firmly clamped in perforation 4, jack 5 and limiting hole 6, thereby effectively limiting the rotation of printing support 2 on hinged frame 3, and ensuring the stability of equipment structure during printing process.

[0031] When the requirement of storing or carrying equipment is needed, first, the position of printing nozzle and related driving components of the equipment needs to be adjusted, by controlling the motor on Z axis (the motor driving and printing nozzle position adjustment are existing mature technology, which will not be repeated here), the X axis driving part together with the printing nozzle is moved to the topmost position of the equipment, so as to ensure that the printing nozzle will not touch the base 1 during the subsequent folding process of printing support 2, so as to avoid the damage of printing nozzle due to collision.

[0032] After the X-axis drive part and the print head position adjustment are completed, the next step is to remove the restriction on the rotation of the print support 2, and the elastic plug-in assembly 7 is pulled by hand. Since the edge of the limiting hole 6 near the side of the through hole 4 and the through hole 4 itself are both inclined, the edge of the through hole 4 is inclined, which facilitates the subsequent insertion of the elastic plug-in assembly 7. During the process of pulling the elastic plug-in assembly 7, the protruding part inside the elastic plug-in assembly 7 gradually retracts. As the pulling action continues, the elastic plug-in assembly 7 smoothly leaves the limiting hole 6 and enters the insertion hole 5 and the through hole 4 in turn. Under the constraint of the inner diameter of the insertion hole 5 and the through hole 4, the internal protruding part remains retracted, waiting for the elastic plug-in assembly 7 to be separated from the through hole 4. At this time, the print support 2 can be rotated relative to the base 1. The rotation angle restriction of the print support 2 on the hinge frame 3 is completely removed. Repeat the operation. When the two elastic plug-in assemblies 7 on the print support 2 complete the above-mentioned restriction removal action, the print support 2 can be manually rotated on the hinge frame 3 until the insertion hole 5 on the print support 2 is rotated to the other through hole 4 on the hinge frame 3. At this time, the print support 2 is just located on the top of the base 1, and the folding is completed. Then, the elastic plug-in assembly 7 is inserted into the corresponding through hole 4 and insertion hole 5 in turn. When the internal part of the elastic plug-in assembly 7 moves to the area where the limiting hole 6 is located, the elastic potential energy stored in it is released due to the fact that it is no longer restricted by the inner diameter of the through hole 4 and the insertion hole 5. The part protrudes into the limiting hole 6 again, re-forming the restriction on the rotation of the print support 2, ensuring the position of the folded print support 2 is stable. Subsequently, the two limiting mechanisms 10 are manually rotated respectively to the opposite side, and finally the two limiting mechanisms 10 enter the long slot 8 at both ends of the print support 2 respectively. When the second magnetic part 11 on the limiting mechanism 10 is rotated to the position opposite to the first magnetic part 9 in the long slot 8, the first magnetic part 9 and the second magnetic part 11 are quickly attracted to each other. By using the limiting mechanism 10 to enter the long slot 8, the limiting mechanism 10 restricts the rotation of the middle part of the print support 2, enhancing the tightness and stability of the print support 2 and the base 1 in the folded state. The first magnetic part 9 and the second magnetic part 11 are quickly attracted to each other, which restricts the rotation of the limiting mechanism 10 itself during movement, effectively preventing the accidental rotation of the limiting mechanism 10 during transportation. Through the folding of the print support 2, the occupied area is greatly reduced, which is convenient for storage and carrying out. If the device needs to be used again later, it only needs to follow the reverse operation sequence to quickly restore the printing state by sequentially removing the magnetic attraction, pulling out the elastic plug-in assembly 7, rotating the print support 2 to the vertical state and reinserting the elastic plug-in assembly 7, and then adjusting the position of the print head.

[0033] In one embodiment, for the above-mentioned elastic plug-in assembly 7, the elastic plug-in assembly 7 comprises an insertion rod 701, and a placement rod 702 is fixedly installed inside the insertion rod 701. The placement rod 702 is symmetrically provided with a spring 703 inside.

[0034] Two ball bearings 704 are fixedly installed at the ends of the two springs 703 that are far apart from each other, and the two ball bearings 704 can be located in the limiting hole 6.

[0035] When it is necessary to store or carry the equipment, hold the insertion rod 701 and pull it outward. When the ball bearing 704 contacts the chamfer on the side of the limiting hole 6 near the through hole 4, as the pulling force increases, the ball bearing 704 is squeezed by the chamfer and retracts into the insertion rod 701, overcoming the elastic force of the spring 703. Continue to pull the insertion rod 701, and the ball bearing 704 completely disengages from the limiting hole 6 and enters the insertion hole 5. Since the inner diameter of the insertion hole 5 is smaller than the outer diameter of the ball bearing 704 when it is extended, the ball bearing 704 continues to be retracted under the constraint of the inner diameter of the insertion hole 5 until the insertion rod 701 disengages from the through hole 4 and the insertion hole 5. The rotation angle restriction of the print holder 2 on the hinge frame 3 is completely released. Repeat this operation until the two elastic insertion components on the print holder 2 are fully engaged. After completing the above-mentioned actions to remove the restrictions, the printer holder 2 can be manually rotated on the hinge frame 3 until the insertion hole 5 on the printer holder 2 rotates to another through hole 4 on the hinge frame 3. At this time, the printer holder 2 is exactly at the top of the base 1, completing the initial folding. Then, insert the insertion rod 701 into the new corresponding through hole 4 and insertion hole 5 in sequence. When the insertion rod 701 is inserted into place, the ball bearing 704 moves to the area where the limiting hole 6 is located. Since it is no longer restricted by the inner diameter of the through hole 4 and insertion hole 5, the spring 703 returns to its natural extended state, pushing the ball bearing 704 back into the limiting hole 6, re-establishing the restriction on the rotation of the printer holder 2, ensuring that the folded printer holder 2 is in a stable position.

[0036] In one embodiment, for the base 1, a connecting plate 101 is symmetrically fixedly installed on the base 1, and both limiting mechanisms 10 include a rotating rod 1001. The two rotating rods 1001 are rotatably installed on the two connecting plates 101 respectively, and a limiting rod 1002 is fixedly installed on the top of the rotating rod 1001.

[0037] A manual wheel 1003 is fixedly installed at the other end of the rotating rod 1001, and the second magnetic component 11 is fixedly installed at the top of the end of the limiting rod 1002 away from the rotating rod 1001.

[0038] When storing the device, the user rotates the manual wheel 1003. The rotation of the manual wheel 1003 drives the rotating rod 1001 to rotate around the connecting plate 101. The limiting rod 1002, which is fixedly connected to the top of the rotating rod 1001, also rotates. Since the position of the long groove 8 after the printing bracket 2 is folded is exactly corresponding to the movement trajectory of the limiting rod 1002, as the rotating rod 1001 continues to rotate, the limiting rod 1002 gradually enters the long groove 8. The limiting rod 1002 blocks the middle of the printing bracket 2, enhancing the tightness and stability of the printing bracket 2 and the base 1 in the folded state. The second magnetic component 11 at the top of the limiting rod 1002 and the first magnetic component 9 in the long groove 8 will attract each other. This not only further enhances the fixing effect of the limiting rod 1002 on the printing bracket 2, but also restricts the rotation of the limiting rod 1002 itself, making the device more stable in the folded state.

[0039] When the device needs to be unfolded for printing, the user turns the manual wheel 1003 again, causing the limiting rod 1002 to rotate under the drive of the rotating rod 1001. The second magnetic component 11 gradually moves away from the adsorption range of the first magnetic component 9. As the rotation continues, the limiting rod 1002 rotates out of the long groove 8, releasing the restriction on the middle part of the printing bracket 2, and preparing for the subsequent rotation of the printing bracket 2 to the working angle and the completion of the device unfolding operation.

[0040] In one embodiment, for the base 1, support legs 102 are fixedly installed at the four bottom corners of the base 1, and handles 103 are fixedly installed on the side wall of the base 1.

[0041] The support legs 102, which are fixedly installed at the four corners of the bottom of the base 1, provide stable support for the entire 3D printing equipment when the equipment is placed normally. When the user needs to move the folded equipment, he / she can hold the handle 103 and lift the handle 103 to move the entire folded 3D printing equipment.
