[0029] Reference Figures 1 to 5 A protective cover securely mounts an ink cartridge, comprising: an ink cartridge body 100 and a protective cover 200. The ink cartridge body 100 has an ink outlet 110, and a snap-fit portion 120 is provided on the lower front side of the ink cartridge body 100. The protective cover 200 has a snap-fit mating portion 210, a lower support portion 220, an upper limit portion 230, a left limit portion 240, and a right limit portion 250. The snap-fit mating portion 210 engages with the snap-fit portion 120, the lower support portion 220 supports the ink cartridge body 100, the upper limit portion 230 limits the upper end of the ink cartridge body 100, and the left and right limit portions 240 and 250 respectively limit the left and right ends of the ink cartridge body 100. The lower support portion 220, upper limit portion 230, left limit portion 240, and right limit portion 250 together form the ink cartridge snap-fit position. The ink cartridge body 100 is engaged with the snap-fit part 120 and the snap-fit mating part 210. The ink cartridge is restricted by the snap-fit mating part 210 from detaching from the protective cover 200 in the front-back direction. The protective cover 200 is engaged with one end of the ink cartridge body 100 by the ink cartridge snap-fit position.
[0030] The ink cartridge described above has its lower front side 100 snapped into the protective cover 200 via a snap-fit part 120. The snap-fit structure restricts the protective cover 200 from coming off. The upper, lower, left, and right ends of the ink cartridge body 100 are respectively limited or supported by the upper limit part 230, the lower support part 220, the left limit part, and the right limit part, so that the protective cover 200 can be firmly installed in the ink cartridge with good installation stability.
[0031] In this embodiment, the ink cartridge body 100 is designed such that, when the ink cartridge body 100 and the protective cover 200 are assembled, its lower front side can be tilted and inserted into the ink cartridge latching position, so that the latching part 120 can engage with the latching mating part 210. When the protective cover 200 is pressed against the ink cartridge body 100, the protective cover 200 can engage one end of the ink cartridge body 100 through the ink cartridge latching position. With the above structure, the installation of the protective cover 200 is convenient. When it is necessary to remove the protective cover 200, the operation can be reversed.
[0032] In this embodiment, the protective cover 200 may be made of plastic or elastic material, thereby allowing for a certain degree of deformation to facilitate assembly and disassembly.
[0033] In this embodiment, the lower support portion 220 includes two support plates 221, which are spaced apart to the left and right, forming a lower limiting position between them. The lower end of the ink cartridge body 100 is inserted into the lower limiting position and is limited by the two support plates 221 to the left and right. This structure better limits the ink cartridge body 100, making the installation of the protective cover 200 more stable.
[0034] In this embodiment, the lower support portion 220 has an upwardly protruding protrusion 2211 at its front end. The locking portion 120 is a block, and the locking mating portion 210 is a slot located on the front side of the protrusion 2211 and adjacent to it. Using the above structure, the locking mating portion 210 is configured as a slot, and the front side of the protrusion 2211 of the lower support portion 220 is used as the locking mating portion 210. This structure is simple and provides a stable fit with the locking portion 120.
[0035] It is conceivable that in some embodiments, the snap-fit part 120 may also be a snap-fit slot, while the snap-fit mating part 210 may be a block, and the specific configuration can be made according to the actual situation.
[0036] In this embodiment, a sliding guide surface 2212 is provided on the rear side of the protrusion 2211. The sliding guide surface 2212 slides with the engaging portion 120 and guides the engaging portion 120 over the protrusion 2211. With this structure, the engaging portion 120 can easily enter the position where it engages with the engaging portion 210. Specifically, the sliding guide surface 2212 can be a sloped surface or an arc-shaped surface.
[0037] In this embodiment, the ink cartridge body 100 is provided with a recess 130 corresponding to the protrusion 2211, and the recess 130 is used to engage with the protrusion 2211. With the above structure, the engagement between the ink cartridge body 100 and the protective cover 200 can be further strengthened. Furthermore, when assembling and disassembling the protective cover 200, the protective cover 200 can also form a pivot structure through the engagement of the recess 130 and the protrusion 2211, facilitating the installation and opening of the protective cover 200.
[0038] In this embodiment, the snap-fit parts 120 are arranged in pairs on the left and right sides of the ink cartridge body 100, and the snap-fit mating parts 210 and the protrusions 2211 are arranged in pairs corresponding to the snap-fit parts 120, so that the snap-fit mating is more balanced and stable.
[0039] In this embodiment, the upper limit stop 230 includes an upper left portion 231 and an upper right portion 232. The upper left portion 231 and the upper right portion 232 are respectively provided with a left right-angled groove and a right right-angled groove for engaging with the upper left and upper right corners of the ink cartridge body 100. With the above structure, the upper limit stop 230 can limit the upper left and upper right corners of the ink cartridge body 100 through the two right-angled grooves, respectively, and the limiting is stable.
[0040] In this embodiment, a handle portion 260 is provided at the upper end of the protective cover 200, and the handle portion 260 is located between the upper left portion 231 and the upper right portion 232. With the above structure, the handle portion 260 can be used to assist in the disassembly of the protective cover 200, thereby facilitating operation.
[0041] In this embodiment, the protective cover 200 is provided with a sealing gasket 270, which seals the ink outlet 110. It is conceivable that in some embodiments, the ink outlet 110 can also be directly sealed by the main body of the protective cover 200.
[0042] In this embodiment, the protective cover 200 includes a front side plate 201, a bottom side plate 202, a left side plate 203, and a right side plate 204. The front end of the bottom side plate 202 is connected to the lower end of the front side plate 201. The front end and lower end of the left side plate 203 are connected to the left end of the front side plate 201 and the left end of the bottom side plate 202, respectively. The front end and lower end of the right side plate 204 are connected to the right end of the front side plate 201 and the right end of the bottom side plate 202, respectively. A lower support portion 220 is disposed on the bottom side plate 202. A left limiting portion 240 and a right limiting portion 250 are disposed on the left side plate 203 and the right side plate 204, respectively. An upper limiting portion 230 is connected to the upper end of the front side plate 201. The protective cover 200 described above has a simple and compact structure and is easy to implement.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
