Description

Technical Field

[0001] This utility model relates to the field of conduit fixing structure technology, specifically to a fixing structure for the ink supply conduit of an inkjet printer. Background Technology

[0002] Inkjet printers are a common office device, consisting of a printhead and ink cartridges that supply ink to the printhead. Early inkjet printers integrated the ink cartridge with the printhead, moving together on the printhead guide rail. Therefore, to minimize the drive load on the printhead, the cartridge volume was generally small, and the ink supply capacity was limited. In recent years, to increase the ink capacity of the cartridges and reduce the frequency of cartridge replacement, a continuous ink supply system has been widely adopted. In a continuous ink supply system, the cartridge and printhead are separate, and ink is transferred between them via ink supply conduits. That is, the cartridge does not move with the printhead; instead, ink is delivered to the printhead via the ink supply conduits. These conduits typically consist of four or more tubes arranged side-by-side, with a main surface and side surfaces. This continuous ink supply system greatly improves the ink supply capacity of the cartridges while also reducing the drive load on the printhead.

[0003] This application improves upon the existing technology. In the existing technology, after a period of use, the ink in the ink supply conduit solidifies and tends to adhere to the inner wall of the conduit, which reduces the ink supply capacity of the ink supply conduit. Therefore, it is necessary to disassemble the ink supply conduit regularly for maintenance or replacement. However, the existing fixed structure of the ink supply conduit makes it inconvenient to disassemble the ink supply conduit, and it is also inconvenient to reinstall after disassembly, maintenance or replacement, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing structure for the ink supply conduit of an inkjet printer, which solves the problem that the existing fixing structure for the ink supply conduit in the background art is inconvenient to operate when disassembling the ink supply conduit, and is also inconvenient to install after disassembly, maintenance or replacement, which is time-consuming and labor-intensive.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A fixing structure for an ink supply conduit of an inkjet printer includes a fixing plate, a first conduit fixing block fixedly connected to the top of the fixing plate, and a second conduit fixing block movably disposed behind the first conduit fixing block; a transmission assembly disposed inside the fixing plate, the transmission assembly including grooves symmetrically formed on the upper surface of the fixing plate, a transmission screw rotatably disposed inside the grooves, and a moving block threadedly connected to the outer wall of the transmission screw; a limit rod movably disposed through the lower end surface of the moving block, the top of the moving block being fixedly connected to the transmission block, and the top of the transmission block being fixedly connected to the bottom of the second conduit fixing block.

[0006] Preferably, a mounting plate is fixedly connected to the rear end face of the fixing plate, and one of the mounting plates has multiple positioning holes arranged in a circular array on one side, and a rotating plate is rotatably provided on one side of the positioning holes.

[0007] Preferably, a handle is fixedly connected to the left side of the rotating plate, and a positioning screw is movably disposed through the surface of the rotating plate, with one end of the positioning screw threaded inside one of the positioning holes.

[0008] Preferably, a worm gear is fixedly connected to the other side of the rotating plate via a connecting rod, and a worm wheel is drivenly connected to the top of the worm gear, with the worm wheel and the transmission screw fixedly connected via a transmission rod.

[0009] Preferably, the top of the fixing plate has multiple positioning grooves between two adjacent grooves, and an arc-shaped plate is inserted into the positioning groove. The arc-shaped plate is made of an elastic element.

[0010] Preferably, mounting blocks are fixedly connected to both sides of the fixing plate, and fixing holes are formed through the surface of the mounting blocks.

[0012] 2. Through the structural design of positioning holes, positioning screws, positioning grooves, and arc-shaped plates, after the ink supply conduit is installed, the positioning screws can be passed through the rotating plate and screwed into the matching positioning holes to fix the rotating plate and prevent it from rotating, thereby improving the stability of the ink supply conduit after installation. At the same time, after the ink supply conduit is installed, multiple arc-shaped plates are inserted into the positioning grooves to better fix the ink supply conduit, so that the ink supply conduit fits against the outer wall of the fixing plate, thereby improving the fixing effect of the ink supply conduit.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-6 An ink supply conduit fixing structure for an inkjet printer includes a fixing plate 1, a first conduit fixing block 7 fixedly connected to the top of the fixing plate 1, and a second conduit fixing block 8 movably disposed behind the first conduit fixing block 7. The transmission assembly is located inside the fixed plate 1. The transmission assembly includes grooves symmetrically opened on the upper surface of the fixed plate 1. A transmission screw 9 is rotatably arranged inside the grooves. A moving block 13 is threadedly connected to the outer wall of the transmission screw 9. A limit rod 17 is movably provided through the lower end surface of the movable block 13. A transmission block 10 is fixedly connected to the top of the movable block 13, and the top of the transmission block 10 is fixedly connected to the bottom of the second guide tube fixing block 8. A mounting plate 16 is fixedly connected to the rear end face of the fixing plate 1. One side of the mounting plate 16 has multiple positioning holes 11 arranged in a ring array. A rotating plate 4 is rotatably provided on one side of the positioning holes 11. A handle 5 is fixedly connected to the left side of the rotating plate 4. A positioning screw 12 is movably provided through the surface of the rotating plate 4, and one end of the positioning screw 12 is threaded inside one of the positioning holes 11. A worm gear 6 is fixedly connected to the other side of the rotating plate 4 through a connecting rod. A worm wheel 3 is drivenly connected to the top of the worm gear 6, and the worm wheel 3 is fixedly connected to the transmission screw 9 through a transmission rod. Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, when installing the ink supply conduit, it can be placed between the first conduit fixing block 7 and the second conduit fixing block 8, and made to fit against the inner wall of the first conduit fixing block 7. Then, by holding the handle 5 and rotating the rotating plate 4, the rotating plate 4 drives the worm gear 6 to rotate. The rotation of the worm gear 6 drives the two worm wheels 3 to rotate simultaneously. The rotation of the two worm wheels 3 drives the two transmission screws 9 to rotate through the two transmission rods. The rotation of the two transmission screws 9 drives the two moving blocks 13 to move. The movement of the two moving blocks 13 drives the second conduit fixing block 8 to move closer to the first conduit fixing block 7 through the two transmission blocks 10, until it contacts the outer wall of the ink supply conduit, thus realizing the installation of the ink supply conduit. Similarly, by rotating the rotating plate 4 in the opposite direction, the ink supply conduit can be disassembled. The operation is simple and the disassembly and assembly are efficient. It solves the problem that the existing ink supply conduit fixing structure is inconvenient to operate when disassembling the ink supply conduit, and it is also inconvenient to install after disassembly, maintenance or replacement, which is time-consuming and laborious.

[0017] The top of the fixing plate 1 has multiple positioning grooves 14 between two adjacent grooves. An arc plate 15 is inserted into the positioning groove 14. The arc plate 15 is made of an elastic element. Mounting blocks 2 are fixedly connected to both sides of the fixing plate 1. Fixing holes are opened through the surface of the mounting blocks 2. Specifically, such as Figure 1 and Figure 5 As shown, during use, after the ink supply conduit is installed, the positioning screw 12 can be passed through the rotating plate 4 and screwed into the matching positioning hole 11 to fix the rotating plate 4 and prevent it from rotating, thereby improving the stability of the ink supply conduit after installation. At the same time, after the ink supply conduit is installed, multiple arc plates 15 are inserted into the positioning groove 14 to better fix the ink supply conduit, so that the ink supply conduit fits against the outer wall of the fixing plate 1, thereby improving the fixing effect of the ink supply conduit. At the same time, before the ink supply conduit needs to be disassembled, the arc plates 15 need to be moved until the multiple arc plates 15 are disengaged from the positioning groove 14, and then the positioning screw 12 is rotated until the positioning screw 12 is disengaged from the rotating plate 4, thereby facilitating the subsequent disassembly of the ink supply conduit.

[0018] Working Principle: In this application, when the ink supply conduit needs to be installed, it can be placed between the first conduit fixing block 7 and the second conduit fixing block 8, and made to fit against the inner wall of the first conduit fixing block 7. Then, by holding the handle 5 and rotating the rotating plate 4, the rotating plate 4 drives the worm gear 6 to rotate. The rotation of the worm gear 6 drives the two worm wheels 3 to rotate simultaneously. The rotation of the two worm wheels 3 drives the two transmission screws 9 to rotate through the two transmission rods. The rotation of the two transmission screws 9 drives the two moving blocks 13 to move. The movement of the two moving blocks 13 drives the second conduit fixing block 8 to move closer to the first conduit fixing block 7 through the two transmission blocks 10, until... The ink supply conduit is installed by contacting the outer wall of the conduit. Similarly, the conduit can be disassembled by rotating the rotating plate 4 in the opposite direction. The operation is simple and the disassembly and assembly are efficient. After the ink supply conduit is installed, the positioning screw 12 can be passed through the rotating plate 4 and screwed into the matching positioning hole 11 to fix the rotating plate 4 and prevent it from rotating, thereby improving the stability of the ink supply conduit after installation. At the same time, after the ink supply conduit is installed, multiple arc-shaped plates 15 are inserted into the positioning groove 14 to better fix the ink supply conduit, so that the ink supply conduit fits against the outer wall of the fixing plate 1, thereby improving the fixing effect of the ink supply conduit.
