[0024] Furthermore, bolts 10 for fixing the mounting frame 3 are installed below the mounting frame 3, so as to facilitate fixing the mounting frame 3 in the printer base.

[0025] The utility model replaces the conventional screw fixing connection mode outside the ink cartridge body 1 with a connecting rod mechanism, so that the ink cartridge body 1 can have a movable characteristic, thereby facilitating the ink cartridge body 1 to avoid the blind area blocked by the printing roller.

[0026] See also Figure 2 In this embodiment, the top of the ink cartridge body 1 has a recessed portion for the ink roller of the printing press to penetrate between the ink cartridge body 1 and the ink cartridge cover 2.

[0027] In this embodiment, the connecting rod mechanism includes a first swing rod 4 and a second swing rod 5 rotatably connected to the mounting frame 3, and the connecting rod mechanism is provided with one on both sides of the ink cartridge body 1. A connecting plate 6 is fixedly installed on the bottom of the ink cartridge body 1, wherein the other ends of the first swing rod 4 and the second swing rod 5 away from the mounting frame 3 are both rotatably connected to the connecting plate 6, and the first swing rod 4 and the second swing rod 5 are arranged horizontally with each other.

[0028] With this design, the first swing arm 4 and the second swing arm 5 can be connected to the mounting frame 3 and the connecting plate 6 to form a parallelogram structure for swinging. On the one hand, the movement trajectory of the ink cartridge body 1 can be changed, so that when the ink cartridge body 1 is pushed outward, it can swing in an arc to the lower low point position to pass over the printing press ink roller that restricts the position of the ink cartridge body 1. On the other hand, the ink cartridge body 1 can be maintained always horizontal to the mounting frame 3, so as to expose the inner wall of the ink cartridge body 1.

[0029] In order to fix the position of the ink cartridge body 1 after the movement, a bottom plate 7 is fixedly installed under the connecting plate 6 in this embodiment. The bottom plate 7 extends to the outside of the connecting plate 6 and is located below the mounting frame 3. A supporting foot 8 for supporting the bottom plate 7 is fixedly installed at the lower end of the bottom plate 7.

[0030] It should be noted that the support foot 8 is threadedly connected to the bottom of the base plate 7 , and the extension length of the support foot 8 relative to the base plate 7 can be changed by rotating the support foot 8 , thereby completing the position support of the base plate 7 .

[0031] In this embodiment, a limiting structure for limiting the lifting of the bottom plate 7 is provided below the mounting frame 3, the limiting structure includes a sliding sleeve 11 fixedly mounted below the mounting frame 3 and a locking member located on the sliding sleeve 11, the locking member includes a cam 12 rotatably connected to the sliding sleeve 11 and a lever 13 located outside the cam 12, and the direction of the raised end of the cam 12 can be changed by toggling the lever 13;

[0032] It also includes a pressing plate 15 located in the sliding sleeve 11 and a pressing pad 17 located on the pressing plate 15 . The sliding sleeve 11 is provided with a mounting hole 14 connected to the middle cavity of the sliding sleeve 11 . The pressing plate 15 and the pressing pad 17 are both slidably connected to the mounting hole 14 .

[0033] Preferably, the mounting hole 14 is T-shaped, the pressure plate 15 and the upper half of the mounting hole 14 are slidably connected to each other, the extrusion pad 17 and the lower half of the mounting hole 14 are slidably connected to each other, and a connecting rod 16 is fixed between the pressure plate 15 and the extrusion pad 17, so that the extrusion pad 17 can be pushed by the pressure plate 15.

[0034] It should be noted that a spring 18 for pushing the pressure plate 15 to return to its original position is installed in the upper half of the mounting hole 14 . One end of the spring 18 is fixedly connected to the lower end of the pressure plate 15 , and the other end is fixed to the inner wall of the mounting hole 14 .

[0035] A limit rod 9 slidably connected to the sliding sleeve 11 is installed below the mounting frame 3 in this embodiment. The limit rod 9 can slide relative to the sliding sleeve 11 and abut against the bottom plate 7 to limit the lifting of the bottom plate 7. At the same time, the limit rod 9 can be squeezed by the squeezing pad 17 to achieve self-locking of the position of the limit rod 9.

[0036] The working principle of the above embodiment is:

[0037] When the ink cartridge body 1 needs to be cleaned, the support foot 8 under the bottom plate 7 is rotated to adjust the extension length relative to the bottom plate 7. At this time, the ink cartridge body 1 connected by the connecting plate 6 can be swung relative to the mounting frame 3. At this time, the ink cartridge body 1 swings around the parallelogram structure formed by the first swing rod 4 and the second swing rod 5, and passes over the limiting position of the printer ink roller on the recess above the ink cartridge body 1 in an arc shape, so that the ink cartridge body 1 moves from the highest point position to the lowest point position, and then the position of the support frame 8 can be adjusted again, and after adjusting the extension length of the limit rod 9 relative to the sliding sleeve 11 by toggling the lever 13, the lever 13 is reset again to limit the position of the limit rod 9, so that the positioning of the ink cartridge body 1 can be achieved, and the inner wall of the ink cartridge body 1 can be completely exposed to the outside, which is convenient for the operator to clean.
