[0002] With the rapid development of technology, 3D printing, as an innovative manufacturing method, has been widely applied in many fields. 3D printing equipment can quickly and accurately manufacture objects with various complex structures by layering materials according to a computer-designed digital model. It has advantages such as high production efficiency, strong design flexibility, low material waste, and suitability for small-batch production, and is widely used in industrial manufacturing, medical, educational, architectural, and artistic creation fields.

[0003] Currently, there are many types of 3D printing equipment on the market, including desktop 3D printers, industrial-grade 3D printers, and medical-grade 3D printers. Desktop 3D printers have become the preferred choice for individual users and small businesses due to their relatively low price and ease of operation.

[0004] A 3D printer has a print head installed to eject material. The print head is bolted to the mounting base. In actual use, the print head will move frequently with the mounting base. During the movement, it is easy to vibrate. The vibration can cause the bolt to reverse and loosen, which in turn can cause the print head to loosen and affect the accuracy of material ejection.

[0005] Furthermore, 3D printers typically have guide shafts for guidance. After a certain period of use, lubricant needs to be applied to the outer wall of the guide shaft to prevent jerking during operation. However, the timing of adding lubricant is difficult to control; failure to lubricate in time will affect the normal operation of the device.

[0006] Therefore, a 3D printing device is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a 3D printing device, comprising a body 1, a guide shaft 2 disposed on the upper surface of the body 1, both the body 1 and the guide shaft 2 being part of a 3D printer, a slide block 5 slidably connected to the outer wall of the guide shaft 2, the slide block 5 being able to slide laterally along the guide shaft 2, a mounting base 3 fixedly connected to the front surface of the slide block 5, the slide block 5 and the mounting base 3 moving synchronously, a print head 4 disposed on the lower surface of the mounting base 3, an anti-loosening component disposed inside the mounting base 3, and an oiling component disposed on the upper surface of the slide block 5.

[0035] Reference Figure 1 - Figure 3 The anti-loosening component includes bolts 61. The print head 4 is fixed to the bottom of the mounting base 3 by bolts 61 to maintain stability. A positioning ring 62 is fixedly connected to the inner wall of the top of the mounting base 3. The positioning ring 62 is sleeved on the outer wall of the bolt 61 and does not contact the bolt 61. A positioning block 63 is fixedly connected to the lower surface of the positioning ring 62. A locking block 65 is elastically connected to the inner wall of the positioning block 63 by compression spring 64. Multiple sets of positioning blocks 63, compression springs 64 and locking blocks 65 are arranged in a circumferential array with the center of the positioning ring 62. A positioning groove 601 is opened on the upper surface of the bolt 61 and a locking groove 602 is opened on the outer wall of the bolt 61.

[0036] Reference Figure 1 , Figure 4 , Figure 5 The lubrication assembly includes a sponge pad 71, which is made of sponge and can absorb a certain amount of lubricating oil. When it is saturated, it will not continue to absorb lubricating oil. A lubrication tube 72 is connected through and fixedly to the upper surface of the slide block 5. The lubrication tube 72 is made of transparent material. A sealing cap 73 is inserted into the upper surface of the lubrication tube 72. A rubber ring 74 is fixedly connected to the outer wall of the sealing cap 73. The rubber ring 74 can maintain a seal. An annular groove 701 is opened at the top of the inner wall of the lubrication tube 72.

[0037] Reference Figure 1 - Figure 3The mounting base 3 and the machine body 1 are electrically connected. Operating the machine body 1 allows the mounting base 3 to move laterally. Bolt 61 passes through and is threaded onto the upper surface of the mounting base 3. Bolt 61 also passes through and is threaded onto the upper surface of the print head 4. Positioning block 63 is inserted into the inner wall of positioning groove 601, which is annular. Positioning block 63 can slide along the inner wall of positioning groove 601. Locking block 65 is inserted into the inner wall of locking slot 602, connecting positioning groove 601 and locking slot 602. One end of compression spring 64 is fixedly connected to the left surface of locking block 65. The other end of the compression spring 64 is fixedly connected to the inner wall on the left side of the positioning block 63. The locking block 65 passes through and slides on the right surface of the positioning block 63. When the locking block 65 moves to the left, it will retract into the positioning block 63 and squeeze the compression spring 64 to generate a reaction force. The right end of the lower surface of the locking block 65 is set as an arc surface. The front and rear surfaces of the locking block 65 are set as arc surfaces. During the insertion process of the locking block 65 and the slot 602, the arc surfaces of the lower and front surfaces of the locking block 65 will be squeezed. When the bolt 61 is unscrewed, the arc surface of the rear surface of the locking block 65 will be squeezed.

[0038] Reference Figure 1 , Figure 4 , Figure 5 The sponge pad 71 is fixedly connected to the inner wall of the slide block 5. The bottom end of the oil filling pipe 72 is set as a cone. The lower surface of the oil filling pipe 72 contacts the upper surface of the sponge pad 71. The upper surface of the sealing cap 73 is fixedly connected with a pull ring for easy pulling. The rubber ring 74 is inserted into the inner wall of the annular groove 701. The rubber ring 74 and the inner wall of the oil filling pipe 72 are interference fit. When the rubber ring 74 and the annular groove 701 are inserted, they can maintain a seal. The rubber ring 74 will deform when squeezed.

[0039] Working principle: When installing the printhead 4, first align the upper surface of the printhead 4 with the lower surface of the mounting base 3, and then tighten the bolt 61. During the tightening process of the bolt 61, the positioning block 63 will be inserted into the positioning groove 601, and the arc surface of the lower and front surfaces of the locking block 65 will be squeezed. The locking block 65 will retract into the positioning block 63 to release the obstruction and will squeeze the compression spring 64 to generate a reaction force. When the bolt 61 is tightened, the printhead 4 will be installed on the mounting base 3, and the slot 602 will be aligned with the locking block 65. The reaction force of the compression spring 64 will push the locking block 65 out and engage with the slot 602.

[0040] Before using the device, the amount of lubricating oil remaining inside the oil filling pipe 72 can be checked from the outside to determine whether oil needs to be added. If oil needs to be added, pull the pull ring upwards to disengage the sealing cap 73 from the oil filling pipe 72, and then add oil into the oil filling pipe 72. After the lubricating oil is added, insert the sealing cap 73 and the oil filling pipe 72 to complete the seal. When the sealing cap 73 is inserted and pulled out, the rubber ring 74 will be squeezed and deformed to prevent obstruction. When the sealing cap 73 and the oil filling pipe 72 are completely inserted, the rubber ring 74 will be inserted into the annular groove 701 to maintain stability.

[0041] At this point, the device can be used. During use, if the bolt 61 reverses due to vibration, it will be unable to rotate significantly due to the obstruction of the locking block 65. After the vibration is relieved, the locking block 65 will push out the squeezing groove 602 due to the force of the compression spring 64, causing the bolt 61 to rotate and tighten. During the movement of the slide 5, the lubricating oil in the sponge pad 71 will adhere to the outer wall of the guide shaft 2 to lubricate it. The lubricating oil in the oil filling pipe 72 will also be absorbed by the sponge pad 71 in time to ensure that the lubricating oil inside the sponge pad 71 is saturated.

[0042] When the printhead 4 needs to be disassembled, keep turning the bolt 61 in reverse. The slot 602 will press the arc surface of the rear surface of the card block 65, causing the card block 65 to retract into the positioning block 63 and release the obstruction. At this time, you can continue to turn the bolt 61 in reverse until it is unscrewed.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
