[0025] The following further elaborates on a cartridge assembly of an inkjet printer proposed by the present utility model in conjunction with the attached drawings and specific embodiments. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the attached drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model. The same or similar reference numerals in the attached drawings represent the same or similar components.

[0026] A cartridge assembly of an inkjet printer, as Figures 1 to 5 shown, includes a cartridge body 1, a top snap-on bracket detachably connected to the top of the cartridge body 1, and a bottom snap-on bracket detachably connected to the bottom of the cartridge body 1. Limiting protrusions are provided on both sides of the cartridge body 1;

[0027] The top snap-on bracket includes a snap-on cross bar 2 and snap-on vertical bars 3 perpendicular to the snap-on cross bar 2. First snap-on portions 4 are provided at both ends of the snap-on cross bar 2, and second snap-on portions 5 are provided at both ends of the snap-on vertical bars 3. The first snap-on portions 4 are snapped onto both sides of the cartridge body 1, and the second snap-on portions 5 are snapped onto both ends of the cartridge body 1. A fitting portion 6 is further provided on the snap-on cross bar 2. The length direction of the fitting portion 6 is parallel to the length direction of the snap-on vertical bars 3. The fitting portion 6 fits onto the top of the cartridge body 1. An elastic pressing strip 7 is provided at one end of the fitting portion 6. The longitudinal section formed by the elastic pressing strip 7 and the fitting portion 6 is U-shaped;

[0028] The bottom snap-on bracket includes a U-shaped sliding bracket 8 with an upward opening. The sliding bracket 8 fits onto the bottom and both ends of the cartridge body 1. A drag reduction member 8a is rotatably provided at the bottom of the sliding bracket 8.

[0029] There is one snap-on cross bar 2 and two snap-on vertical bars 3. The snap-on cross bar 2 and the two snap-on vertical bars 3 form a "艹" shape. The fitting portion 6 is located between the two snap-on vertical bars 3.

[0030] Two sliding frames 8 are provided, and several sliding parts 8b are provided between the two sliding frames 8. The drag-reducing component 8a is located on the sliding frame 8 and the sliding part 8b (wherein the drag-reducing component 8a can be multiple rotating balls or a long strip roller as shown in the figure). The inner sides of both ends of the sliding frame 8, the inner side of the free end of the first fastening part 4, and the inner side of the free end of the second fastening part 5 are all provided with protrusions (not shown in the figure). The outer wall of the ink cartridge body 1 is provided with grooves that cooperate with the protrusions (but do not penetrate the ink cartridge body 1). Firstly, the first fastening part 4, the second fastening part 5, and the sliding frame 8 all have a certain degree of elasticity, preferably made of plastic or other materials. In this way, after elastic deformation, the protrusions can move to the side of the ink cartridge body 1. Finally, after the protrusions are engaged in the corresponding grooves, the connection stability between the top fastening frame and the bottom fastening frame and the ink cartridge body 1 can be improved. At the same time, the stability of the ink cartridge body 1 during assembly and movement can also be improved. An air inlet 1a (and an ink outlet) is provided on one side of the ink cartridge body 1, and the end of the elastic pressure strip 7 near the air inlet 1a is connected to the end of the fastening part near the air inlet 1a.

[0031] The top of the elastic pressure bar 7 is provided with a plurality of flexible stabilizing parts 9 at an angle, and the free ends of the flexible stabilizing parts 9 all face away from the air inlet 1a. The two ends of the flexible stabilizing parts 9 are flush with the two sides of the elastic pressure bar 7. A pressing part 10 is provided at the top of the end of the elastic pressure bar 7 away from the air inlet 1a, and the longitudinal section of the pressing part 10 is an arc shape with an opening facing downward.

[0032] The limiting protrusion includes an upper protrusion 11 and a lower protrusion 12. The upper protrusion 11 is higher than the lower protrusion 12. In use, both outer sides of the upper protrusion 11 and the lower protrusion 12 abut against the outside. The limiting protrusion also includes a stabilizing protrusion 13. The top of the stabilizing protrusion 13 is lower than the top of the lower protrusion 12. The vertical projection of the stabilizing protrusion 13 is located between the vertical projection of the lower protrusion 12 and the vertical projection of the air inlet 1a.

[0033] Two lower protrusions 12 are spaced apart, and a drag-reducing frame 14 is also included. Both ends of the drag-reducing frame 14 abut against the tops of the two lower protrusions 12. A drag-reducing frame 15 is provided on the lower side of the middle part of the drag-reducing frame 14. The drag-reducing frame 15 is a cover-shaped structure with an opening facing outwards. Several drag-reducing columns 16 are vertically rotatably arranged inside the drag-reducing frame 15. Guide portions 17 are provided on both sides of the drag-reducing frame 15. The two sides of the guide portions 17 are respectively attached to the drag-reducing frame 15 and the lower protrusions 12. The bottom of the guide portion 17 abuts against one side of the lower protrusion 12 and is inclined.

[0034] The utility model provides an ink cartridge assembly for an inkjet printer. The support base of the ink cartridge is used in cooperation with the ink cartridge assembly. The base includes a horizontal plate and a vertical plate perpendicular to the horizontal plate. At the same time, two openings are provided on the vertical plate for the air inlet 1a and the ink outlet of the ink cartridge body 1 to pass through. Secondly, limiting plates are provided on both sides of the horizontal plate, both sides of the vertical plate, and the top of the vertical plate to improve the strength of the base and also to limit the ink cartridge body 1.

[0035] When connecting the ink cartridge body 1 to the base, both sides of the ink cartridge body 1 abut against the side limiting plates, so as to ensure the horizontal position of the ink cartridge body 1. Secondly, the top snap-on rack and the ink cartridge body 1 are in a snap-on state, and the bottom snap-on rack is also in a snap-on state with the ink cartridge body 1, that is, both the top snap-on rack and the bottom snap-on rack can be snapped onto the ink cartridge body 1 at any time for use. Secondly, both the top snap-on rack and the bottom snap-on rack can be recycled, reducing the use cost. During the process of connecting the ink cartridge body 1 to the base, the sliding rack 8 is movably abutted against the support base through the friction-reducing member 8a that can rotate at its bottom, so that not only the assembly resistance is reduced, but also the ink cartridge body 1 and the support base can be protected.

[0036] After the ink cartridge body 1 is connected to the base, the bottom of the ink cartridge body 1 abuts against the horizontal plate, and at the same time, the upper side of the elastic pressing strip 7 is fitted to the bottom of the top limiting plate. Thus, under the elastic force of the elastic pressing strip 7, the upper and lower sides of the ink cartridge body 1 can also ensure the stability of their positions, so that the ink outlet and the air inlet 1a of the ink cartridge body 1 can be better connected to the outside, not only improving the assembly efficiency, but also better preventing the ink cartridge body 1 and the external connection structure from being damaged, and the assembly effect is better.

[0037] The cross shape formed by the snap-on horizontal strip 2 and the snap-on vertical strip 3 can improve the connection stability between the top snap-on rack and the ink cartridge body 1, and also improve the position and angle stability of the fitting part 6. When connecting the ink cartridge body 1 to the base, the ink cartridge body 1 is directly pushed towards the vertical plate; during the forward movement of the ink cartridge body 1, the connection end of the fitting part 6 and the elastic pressing strip 7 first acts on the lower side of the top limiting plate. At this time, the ink cartridge body 1 can be directly pushed forward, and the elastic pressing strip 7 can be pressed down by the limiting plate, or the pressing part 10 can be manually pressed down and then the ink cartridge body 1 can be pushed forward; when the position of the ink cartridge body 1 is appropriate, at this time, the top of the elastic pressing strip 7 is in interference contact with the lower side of the top limiting plate, which can improve the position stability of the ink cartridge body 1; not only that, since the flexible stabilizing part 9 can deform (such as made of rubber material), so if the ink cartridge body 1 has a tendency to move outwards, at this time, it will cause the flexible stabilizing part 9 to deform towards the trend of becoming thicker, so as to increase the resistance of the ink cartridge body 1 to move, thereby improving the position stability of the ink cartridge body 1.

[0038] During the installation of the ink cartridge body 1, a limiting strip is provided on the inner side of the limiting plate of the horizontal plate. The top of the limiting strip is attached to the top of the drag-reducing bracket 14. After installation, the limiting strip can also limit the components and the lower protrusion 12, further improving the positional stability of the ink cartridge body 1. At the same time, there is an opening on the downstream side of the limiting part, and there is an elastic strip inside the opening. The inner side of the free end of the elastic strip has a protrusion. This protrusion can be driven outward by the stabilizing protrusion 13 and finally abut against the side of the stabilizing protrusion away from the vertical plate. In this way, the protrusion and the elastic strip can further improve the connection stability between the ink cartridge body 1 and the base. At the same time, in the horizontal direction, the upper protrusion 11, the lower protrusion 12 and the stabilizing protrusion 13 can all abut against the inner side of the limiting plate, thus making the connection between the ink cartridge body 1 and the base more accurate.

[0039] Before installing the ink cartridge body 1 onto the base, the drag-reducing frame 15 needs to be installed onto the lower protrusion 12. During installation, simply insert the drag-reducing frame 15 downwards between the two lower protrusions 12. The inclined shape at the bottom of the guide 17 facilitates the installation of the drag-reducing frame 15 between the lower protrusions 12. When pushing the ink cartridge body 1, the drag-reducing post 16 can reduce some of the resistance of the ink cartridge body 1 (in actual use, the outer side of the drag-reducing post 16 can fully abut against the inner side of the limiting plate, while the lower protrusion 12 can abut, but the abutment force is small), making it relatively easy for the ink cartridge body 1 to be installed onto the base. Similarly, the drag-reducing bracket 14 and the drag-reducing frame 15 are reusable and not disposable.

[0040] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
