[0025] See Figure 1 , this embodiment discloses a main pipe quick installation component for a small character inkjet printer. The main pipe 7 of the inkjet printer is connected to the inkjet printer housing 8 through this component, and the quick disassembly and assembly of the main pipe 7 of the inkjet printer can be realized through this component.

[0026] Combined with Figures 2 - 4 , the main pipe quick installation component for a small character inkjet printer includes a pipe fitting module 1 and a housing fitting module 2. The pipe fitting module 1 is used to connect the main pipe 7 of the inkjet printer, the housing fitting module 2 is used to connect the inkjet printer housing 8, and the pipe fitting module 1 is detachably connected to the housing fitting module 2.

[0027] Specifically, combined with Figure 5, the pipe fitting module 1 includes a pipe mounting block 11 and a plurality of first joint pipelines 12 connected to the pipe mounting block 11.

[0028] In this embodiment, the pipe mounting block 11 is configured as a rectangular block structure, which is convenient for processing and easy to install. In other embodiments, other shaped block structures can also be adopted according to actual needs. As Figure 5 shown, the pipe mounting block 11 is provided with threaded holes for connecting fasteners 9 such as bolts, and the use of these threaded holes will be specifically introduced below.

[0029] The first joint pipeline 12 is used to connect pipelines such as the ink pipe and the dilution pipe of the inkjet printer main pipe 7. The first joint pipeline 12 is arranged at the central position of the pipe mounting block 11. Correspondingly, the pipe mounting block 11 is provided with first mounting through holes 111 matching the number of the first joint pipelines 12. One end of the first joint pipeline 12 is inserted into the first mounting through hole 111, and the other end is connected to the inkjet printer main pipe 7. To ensure the connection tightness between the first joint pipeline 12 and the pipe mounting block 11 and prevent ink or cleaning liquid from leaking, in this embodiment, the pipe mounting block 11 is made of an organic synthetic material with a certain elasticity, the first joint pipeline 12 is made of stainless steel, and at least two groups of tower-shaped annular protrusions 121 are respectively provided at both ends of the first joint pipeline 12, and the outer diameter of the annular protrusion 121 is slightly larger than the inner diameter of the first mounting through hole 111. As Figure 7 shown, this structure can make the annular protrusion 121 tightly fitted in the first mounting through hole 111 and can also ensure the connection stability between the first joint pipeline 12 and the pipe mounting block 11.

[0030] Combined with Figure 6 , the housing fitting module 2 includes a housing mounting block 21 and a plurality of second joint pipelines 22 connected to the housing mounting block 21.

[0031] In this embodiment, the housing mounting block 21 and the pipe mounting block 11 have the same shape. Specifically, the pipe mounting block 11 and the housing mounting block 21 are respectively provided with a first threaded hole 3 and a second threaded hole 4 for connecting bolts. The first threaded hole 3 is used to connect the two mounting blocks to the inkjet printer main pipe 7 and the inkjet printer housing 8. The first threaded hole 3 is arranged at the four corners of the two mounting blocks to strengthen the connection stability; the second threaded hole 4 is used for connecting between the two mounting blocks, and it is arranged staggeredly between the first threaded holes 3. During installation, the housing mounting block 21 is butted against the pipe mounting block 11. After the fastening bolts pass through the second threaded hole 4 to fasten the two, they are installed on the inkjet printer main pipe 7, and then another type of fastening bolt is used to pass through the first threaded hole 3 to install the fastened two modules and the inkjet printer main pipe 7 on the inkjet printer housing 8.

[0032] On one side facing the pipe mounting block 11, the casing mounting block 21 is fixedly provided with a tubular protrusion 211 adapted to the first mounting through-hole 111. The tubular protrusion 211 extends to the other side of the first mounting through-hole 111, and a conveying pipeline is axially provided along the center of the tubular protrusion 211. Through the cooperation of the tubular protrusion 211 and the first mounting through-hole 111, not only can the flow channel connection be achieved, but also the positioning function can be realized, making the installation of the two mounting blocks faster and more accurate.

[0033] The casing mounting block 21 is provided with a second mounting through-hole 212 communicating with the conveying channel. One end of the second joint pipeline 22 is inserted into the second mounting through-hole 212, and the other end is connected to the ink pipe and the diluent pipeline of the ink path system in the inkjet printer casing 8. Through the connection of the first joint pipeline 12, the tubular protrusion 211, and the second joint pipeline 22, a complete flow channel for liquids such as ink or diluent to pass through is formed. The casing mounting block 21 and the pipe mounting block 11 are made of the same material. The second joint pipeline 22 and the first joint pipeline 12 have the same structure and material, and the matching structure with the second mounting through-hole 212 is the same as the matching structure of the first joint pipeline 12 and the first mounting through-hole 111.

[0034] Furthermore, the tubular protrusion 211 includes an integrally formed upper protrusion and a lower protrusion that are coaxial. The outer diameter of the upper protrusion is smaller than the outer diameter of the lower protrusion, and the structure of the corresponding side space of the first mounting through-hole 111 matches the structure of the tubular protrusion 211. In this embodiment, the main pipe quick-installation assembly further includes a sealing ring 5 sleeved outside the upper protrusion with a smaller outer diameter. The sealing ring 5 abuts against the inner wall of the first mounting through-hole 111. By installing the sealing ring 5, it can prevent ink or cleaning liquid from leaking from the connection position between the tubular protrusion 211 and the first mounting through-hole 111.

[0035] See Figure 4 , for the convenience of connecting the lines of the main pipe 7 of the inkjet printer, the casing mounting block 21 and the pipe mounting block 11 are respectively provided with through-holes 6. The lines of the main pipe 7 of the inkjet printer pass through the through-holes 6 and enter the inkjet printer casing 8 and are connected to the circuit board. The through-holes 6 can be set as a straight shape along the length direction of the mounting block, or can be set as an L shape or a U shape, which is selected according to actual needs. The through-holes 6 can also play a role in reducing the weight of the mounting block, making the overall installation more stable and reliable.

[0036] The main pipe quick-installation component for a small-character inkjet printer provided in this embodiment has a simple structure and low manufacturing cost. By arranging a pipe matching module 1 and a housing matching module 2 that are connected to each other between the main pipe 7 of the inkjet printer and the housing 8 of the inkjet printer, the quick installation and disassembly of the main pipe and the housing can be achieved. When replacing the main pipe, only the fastening bolts with the pipe installation block 11 need to be removed and a new main pipe with the pipe installation block 11 can be replaced, without the need to disassemble the pipelines in the ink path system. This embodiment can achieve the modular design of the main pipe. The joint pipelines, installation through holes, and sealing structures arranged between the two modules can achieve the connection of liquid pipelines such as ink pipes and dilution pipes, and ensure that liquids such as ink and dilution liquid do not leak under normal working pressure.
