Description

Technical Field

[0001] This application relates to the field of stationery technology, and more specifically to an ink cartridge storage device. Background Technology

[0002] As a classic writing instrument, the fountain pen is favored by many writing enthusiasts and professionals. The use of a fountain pen is inseparable from its ink cartridges, which serve as the ink supply device, providing a convenient way to refill the ink. However, with the increasing use of ink cartridges, their storage and management issues have become increasingly prominent. Traditional ink cartridge storage methods often involve placing them haphazardly on desks, in drawers, or cardboard boxes. This not only easily leads to collisions and compression between cartridges but also can cause dust or stains to accumulate on the surface, affecting the cartridge's seal and lifespan. Furthermore, when it's time to replace an ink cartridge, users often have to spend a significant amount of time searching for a suitable cartridge in a cluttered environment, greatly reducing writing efficiency. On the other hand, the material of ink cartridges is usually quite soft and easily deformed or damaged by external forces. Once a cartridge is damaged, ink may leak, not only contaminating surrounding items but also potentially damaging the fountain pen. In addition, the differences in size and shape of ink cartridges between different brands and models of fountain pens further complicate the standardized storage of ink cartridges. Currently, while there are some simple storage boxes or pencil cases on the market for storing pens and ink cartridges, these products are mostly single-function and cannot meet users' diverse needs for ink cartridge sorting, protection, and convenient access. Therefore, there is still a need for an ink cartridge storage device that can effectively protect ink cartridges, facilitate sorting and storage, and allow for quick access. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide an ink cartridge storage device that adopts a press-type locking mechanism. The latch and the locking mechanism are locked and unlocked by pressing the cover. The storage seat automatically pops out when the device is unlocked by adding a first elastic element. This not only effectively protects the ink cartridge, but also has the advantages of simple and labor-saving operation and quick access to the ink cartridge.

[0004] This application provides an ink cartridge storage device, including a housing and a storage base. The storage base is slidably installed inside the housing and can pop out or retract relative to the housing. The storage base has a storage cavity for accommodating multiple ink cartridges. The top of the storage base has a cover for opening and closing the housing. The housing has a locking mechanism, and the bottom of the storage base has a latch adapted to the locking mechanism. The latch is slidably connected to the locking mechanism to lock the storage base inside the housing. A first elastic element is provided between the storage base and the housing. The cover is pressed against the storage base to unlock the latch from the locking mechanism, and the storage base pops out relative to the housing under the action of the first elastic element.

[0005] In this technical solution, the storage base is slidably installed inside the housing, giving it a retractable function. Users can pull the storage base out or push it back in as needed for convenient access and storage of ink cartridges. The storage cavity allows multiple ink cartridges to be placed together, avoiding collisions and compression between them, and also facilitating the classification and management of the ink cartridges. A cover is provided on the top of the storage base. When the storage base slides out, it extends the cover to open the housing; when the storage base slides back, it retracts the cover to close the housing, effectively protecting the ink cartridges inside the storage cavity and preventing dust, stains, or other external factors from contaminating them. A locking mechanism is provided inside the housing, and a latch is provided at the bottom of the storage base. The cooperation of the locking mechanism and the latch enables the fixing and unlocking functions between the storage base and the housing. The locking mechanism adopts a press-type locking mechanism. Pressing the cover locks and unlocks the latch and the locking mechanism, linking the latch and the cover, so that the cover not only protects the storage cartridges but also... The cavity also serves as a locking and unlocking mechanism. When the cover is pressed, it triggers the locking mechanism via the storage seat, simplifying the operation and reducing the need for additional buttons or components, making the entire device more concise and compact. A first elastic element is provided between the storage seat and the housing. After the locking mechanism is unlocked, the first elastic element pushes the storage seat to slide out. When the user presses the cover, the storage seat causes the locking mechanism to slide downwards, and the locking mechanism is engaged, locking the storage seat inside the housing while the cover remains closed. When the user presses the cover again, the storage seat causes the locking mechanism to slide downwards, disengaging from the locking mechanism and unlocking the storage seat. Under the elastic restoring force of the first elastic element, the storage seat automatically pops out from the housing, allowing the user to directly retrieve the ink cartridge from inside. This not only improves the convenience and enjoyment of operation but also reduces manual operation steps, enhancing the user experience.

[0006] As an improvement, the storage base is provided with at least one partition plate extending along the center of the storage base towards its side wall to evenly divide the storage cavity into multiple sections. In this technical solution, the partition plate inside the storage base divides the storage cavity into multiple independent storage areas, each capable of accommodating multiple ink cartridges. This allows the storage device to better adapt to ink cartridges of different sizes and shapes, while also facilitating user classification and management of the ink cartridges. The partition plate can be fixed or adjustable, and its number and layout can be adjusted according to the size and shape of the storage cavity. The specific design depends on the purpose of the storage device and user needs, enhancing the user experience and the practicality of the storage device.

[0007] As an improvement, the storage base is provided with a connecting rod, and the cover is provided with a first mounting groove adapted to the connecting rod. The top of the connecting rod is inserted into the first mounting groove. In this technical solution, a connecting rod is provided on the storage base, and the connecting rod is integrally formed on the storage base. The integrally formed connecting rod and the storage base are structurally more robust, and both production and installation are simplified. The connecting rod connects the storage base and the cover together, and transmits pressing force to realize the locking and unlocking operations of the latch and locking mechanism. The cover is provided with a first mounting groove, the shape and size of which match the connecting rod, so that the connecting rod can be inserted into it and form a stable connection with the cover. The user only needs to press the cover, and the force is transmitted to the latch through the connecting rod to realize unlocking. The structure is simple, the operation is convenient, and no additional fasteners are required, reducing manufacturing costs and assembly difficulty.

[0008] As an improvement, the top of the connecting rod is provided with a first positioning protrusion, and the first mounting groove is provided with a first positioning hole adapted to the first positioning protrusion. The first positioning protrusion and the first positioning hole are connected to restrict the relative rotation of the storage base and the cover. In this technical solution, the top of the connecting rod is provided with a first positioning protrusion, which is integrally formed with the connecting rod. The first mounting groove is provided with a first positioning hole, the shape and size of which match the first positioning protrusion to ensure that the two can fit tightly. When the connecting rod is inserted into the first mounting groove, the first positioning protrusion will be inserted into the first positioning hole. This not only realizes the mechanical connection between the storage base and the cover, but also restricts the relative rotation between the two through the cooperation of the positioning protrusion and the positioning hole. This ensures that the cover can stably transmit force during the pressing operation without causing operational failure due to rotation.

[0009] As an improvement, the side wall of the storage base is provided with a second positioning protrusion, and the inner wall of the housing is provided with a slide rail adapted to the second positioning protrusion. The second positioning protrusion is connected to the slide rail so that the storage base can slide relative to the housing. In this technical solution, the side wall of the storage base is provided with a second positioning protrusion, which is integrally formed with the storage base. The inner wall of the housing is provided with a slide rail, the shape and size of which match the positioning protrusion to ensure that the two can fit tightly. The slide rail extends along the sliding direction of the storage base, providing guidance and support for the sliding of the storage base. When the storage base is installed in the housing, the second positioning protrusion will insert into the slide rail, which not only realizes the connection between the storage base and the housing, but also provides guidance and support for the sliding of the storage base through the slide rail. The sliding of the storage base is more stable and smooth, enhancing the structural stability between the storage base and the housing.

[0010] As an improvement, the height of the side wall of the storage holder is less than or equal to half the height of the housing. The inner wall of the housing is provided with a limiting protrusion adapted to the storage holder. The limiting protrusion is used to abut against the top of the side wall of the storage holder, so that the side wall of the storage holder is confined within the housing when the storage holder pops out. In this technical solution, by setting the height of the side wall of the storage holder to be less than or equal to half the height of the housing, it is ensured that when the storage holder pops out, its side wall will not exceed the range of the housing. This ensures that the storage holder will not obstruct the user from taking out the ink cartridge when it is extended, leaving sufficient space for the user to take it out. The limiting protrusion on the inner wall of the housing is used to abut against the top of the side wall of the storage holder. When the storage holder pops out, the limiting protrusion will abut against the top of the side wall of the storage holder, thereby limiting the sliding range of the storage holder. This ensures that the storage holder will not exceed the range of the housing when it pops out. The user can easily reach into the storage cavity to directly take out the ink cartridge without being blocked by the side wall of the storage holder, improving usage efficiency and satisfaction.

[0011] As an improvement, the housing includes a sleeve and a base, which are detachably connected. The storage seat is slidably connected to the sleeve, and the locking mechanism is mounted on the base. In this technical solution, the housing is divided into two main parts: a sleeve and a base. The sleeve is mainly used to accommodate the storage seat and provide a sliding track, while the base is used to install the locking mechanism and provide support for the entire device. The detachable connection design of the sleeve and base makes the assembly and maintenance of the entire device more convenient. Users can easily disassemble the sleeve and base for cleaning or replacement of parts.

[0012] As an improvement, the base is provided with a first mounting seat adapted to the locking mechanism. The locking mechanism is installed inside the first mounting seat, and the first elastic element is fitted outside the first mounting seat. In this technical solution, a first mounting seat is added to the base. Its shape and size are designed to accommodate and fix the locking mechanism, ensuring stable installation of the locking mechanism inside the base, providing precise positioning and support, reducing damage caused by external impacts or vibrations, and improving the operational reliability of the locking mechanism.

[0013] As an improvement, the base is provided with a second mounting seat adapted to the first elastic element, and the bottom of the storage seat is provided with a third mounting seat adapted to the first elastic element. One end of the first elastic element is located within the second mounting seat, and the other end of the first elastic element is located within the third mounting seat. In this technical solution, the base is provided with a second mounting seat, the shape and size of which are designed to accommodate one end of the first elastic element. The bottom of the storage seat is provided with a third mounting seat, the shape and size of which are designed to accommodate the other end of the first elastic element. Both the second and third mounting seats have a certain depth and shape to match the shape of the first elastic element, ensuring that it can be firmly installed between the storage seat and the base, reducing the shaking or displacement of the first elastic element during use, and improving the reliability of the entire device.

[0014] As an improvement, the outer wall of the sleeve is provided with a plurality of third positioning protrusions, and the inner wall of the base is provided with a snap groove that matches the third positioning protrusions. The third positioning protrusions and the snap groove are elastically snapped together to lock the sleeve and the base together. In this technical solution, the third positioning protrusion is a protruding part on the outer wall of the sleeve. The third positioning protrusion has a certain degree of elasticity. The inner wall of the base is provided with a locking groove. The shape and size of the locking groove match the third positioning protrusion, ensuring that when the sleeve is inserted into the base, the third positioning protrusion can smoothly enter the locking groove and achieve elastic locking. The elastic deformation of the third positioning protrusion achieves engagement or disengagement with the locking groove. The connection between the sleeve and the base is reliable, effectively preventing the sleeve from accidentally loosening during normal use and ensuring the stability of the entire device. Moreover, the elastic locking design makes the assembly and disassembly of the sleeve and the base very convenient. The user only needs to insert the sleeve into the base, and the third positioning protrusion will automatically lock into the locking groove to complete the connection. When disassembling, only a certain external force needs to be applied to make the third positioning protrusion disengage from the locking groove. When the user needs to clean or replace parts, the sleeve and the base can be easily disassembled for maintenance operations and then reassembled. The operation is simple and quick.

[0026] like Figures 1 to 6 As shown, this application discloses an ink cartridge storage device, including a housing 1 and a storage base 2. The storage base 2 is slidably installed inside the housing 1. The storage base 2 can pop out or retract relative to the housing 1. The storage base 2 is provided with a storage cavity 21 for accommodating multiple ink cartridges. The top of the storage base 2 is provided with a cover 3 for opening and closing the housing 1. The storage base 2 is slidably installed inside the housing 1, so that the storage base 2 has a telescopic function. Users can pull out or push back the storage base 2 from the housing 1 as needed, which is convenient for taking out and storing ink cartridges. The setting of the storage cavity 21 allows multiple ink cartridges to be placed in a concentrated manner, avoiding mutual collision and compression between ink cartridges. It also makes it convenient for users to classify and manage ink cartridges. The cover 3 is provided on the top of the storage base 2. When the storage base 2 pops out, it drives the cover 3 to extend and open the housing 1. When the storage base 2 slides back, it drives the cover 3 to retract and close the housing 1, effectively protecting the ink cartridges in the storage cavity 21 and preventing dust, stains or other external factors from contaminating the ink cartridges.

[0027] The housing 1 is equipped with a locking mechanism 4, and the bottom of the storage base 2 is equipped with a latch 22 that is compatible with the locking mechanism 4. The latch 22 is slidably connected to the locking mechanism 4 to lock the storage base 2 inside the housing 1. The cooperation between the locking mechanism 4 and the latch 22 realizes the fixing and unlocking functions between the storage base 2 and the housing 1. The locking mechanism 4 is a press-type locking mechanism 4. By pressing the cover 3, the latch 22 and the locking mechanism 4 are locked and unlocked. The latch 22 and the cover 3 are linked, so that the cover 3 not only protects the storage cavity 21, but also undertakes the locking and unlocking functions. When the cover 3 is pressed, the cover 3 triggers the latch 22 to separate or engage with the locking mechanism 4 through the storage base 2, which simplifies the operation steps, reduces the need for additional buttons or parts, and makes the whole device more concise and compact.

[0028] like Figure 2and Figure 3 As shown, a first elastic element 5 is provided between the storage base 2 and the housing 1. The cover 3 is pressed against the storage base 2, causing the latch 22 to be unlocked by the locking mechanism 4. Under the action of the first elastic element 5, the storage base 2 pops out relative to the housing 1. The first elastic element 5 is provided between the storage base 2 and the housing 1. After the latch 22 is unlocked by the locking mechanism 4, the first elastic element 5 pushes the storage base 2 out. When the user presses the cover 3, the storage base 2 drives the latch 22 to slide down. The latch 22 is connected to the locking mechanism 4, so that the storage base 2 is locked inside the housing 1. The cover 3 remains closed to the housing 1. When the user presses the cover 3 again, the storage base 2 drives the latch 22 to slide down. The latch 22 is disengaged from the locking mechanism 4, so that the storage base 2 slides out. Under the elastic restoring force of the first elastic element 5, the storage base 2 will automatically pop out from the housing 1, making it convenient for the user to directly take out the ink cartridge from the storage base 2. This not only improves the convenience and fun of operation, but also reduces the steps of manual operation by the user, thus improving the user experience.

[0029] More specifically, such as Figure 2 and Figure 3 As shown, the storage base 2 is provided with at least one partition plate 23. The partition plate 23 extends along the center of the storage base 2 towards the side wall of the storage base 2 to evenly divide the storage cavity 21 into multiple parts. The partition plate 23 is added to the storage base 2 to divide the storage cavity 21 into multiple independent storage areas. Each area can accommodate multiple ink cartridges, so that the storage device can better adapt to ink cartridges of different sizes and shapes. It also makes it easier for users to classify and manage ink cartridges. The partition plate 23 can be fixed or adjustable. The number and layout of the partition plate 23 can be adjusted according to the size and shape of the storage cavity 21. The specific design depends on the purpose of the storage device and user needs, improving the user experience and the practicality of the storage device.

[0030] More specifically, such as Figures 3 to 5 As shown, the storage base 2 is provided with a connecting rod 24, and the cover 3 is provided with a first mounting groove 31 that is adapted to the connecting rod 24. The top of the connecting rod 24 is inserted into the first mounting groove 31. The connecting rod 24 is set on the storage base 2 and is integrally formed on the storage base 2. The integrally formed connecting rod 24 and the storage base 2 are more structurally robust, and the production and installation are simplified. The connecting rod 24 connects the storage base 2 and the cover 3 together and transmits the pressing force to realize the locking and unlocking operation of the latch 22 and the locking mechanism 4. The cover 3 is provided with a first mounting groove 31. The shape and size of the first mounting groove 31 match the connecting rod 24, so that the connecting rod 24 can be inserted into it and form a stable connection with the cover 3. The user only needs to press the cover 3 simply, and the force is transmitted to the latch 22 through the connecting rod 24 to unlock. The structure is simple, the operation is convenient, and no additional fasteners are required, which reduces the manufacturing cost and assembly difficulty.

[0031] More specifically, such as Figures 3 to 5 As shown, the top of the connecting rod 24 is provided with a first positioning protrusion 241, and the first mounting groove 31 is provided with a first positioning hole 311 that matches the first positioning protrusion 241. The first positioning protrusion 241 is connected to the first positioning hole 311 to restrict the relative rotation of the storage base 2 and the cover 3. The top of the connecting rod 24 is provided with a first positioning protrusion 241, which is integrally formed with the connecting rod 24. The first mounting groove 31 is provided with a first positioning hole 311, and the shape and size of the first positioning hole 311 match the first positioning protrusion 241 to ensure that the two can fit tightly. When the connecting rod 24 is inserted into the first mounting groove 31, the first positioning protrusion 241 will be inserted into the first positioning hole 311. This not only realizes the mechanical connection between the storage base 2 and the cover 3, but also restricts the relative rotation between the two through the cooperation of the positioning protrusion and the positioning hole, ensuring that the cover 3 can stably transmit force during the pressing operation without causing the operation to fail due to rotation.

[0032] More specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the side wall of the storage base 2 is provided with a second positioning protrusion 25, and the inner wall of the housing 1 is provided with a slide rail 11 adapted to the second positioning protrusion 25. The second positioning protrusion 25 is connected to the slide rail 11 so that the storage base 2 can slide relative to the housing 1. The side wall of the storage base 2 is provided with a second positioning protrusion 25, and the second positioning protrusion 25 is integrally formed with the storage base 2. The inner wall of the housing 1 is provided with a slide rail 11. The shape and size of the slide rail 11 match the positioning protrusion to ensure that the two can fit tightly. The slide rail 11 extends along the sliding direction of the storage base 2, providing guidance and support for the sliding of the storage base 2. When the storage base 2 is installed in the housing 1, the second positioning protrusion 25 will be inserted into the slide rail 11. This not only realizes the connection between the storage base 2 and the housing 1, but also provides guidance and support for the sliding of the storage base 2 through the slide rail 11. The sliding of the storage base 2 is more stable and smooth, enhancing the structural stability between the storage base 2 and the housing 1.

[0033] More specifically, such as Figure 2 and Figure 3As shown, the height of the side wall of the storage base 2 is less than or equal to half the height of the housing 1. The inner wall of the housing 1 is provided with a limiting protrusion 12 that is adapted to the storage base 2. The limiting protrusion 12 is used to abut against the top of the side wall of the storage base 2, so that when the storage base 2 pops out, the side wall of the storage base 2 is limited to inside the housing 1. By setting the height of the side wall of the storage base 2 to be less than or equal to half the height of the housing 1, the height of the side wall of the storage base 2 is limited to ensure that when the storage base 2 pops out, its side wall will not exceed the range of the housing 1, so that the storage base 2 will not be extended in the extended state. To prevent obstruction of the user's access to the ink cartridge and to provide sufficient space for the user to access it, a limiting protrusion 12 is provided on the inner wall of the housing 1. The limiting protrusion 12 is used to abut against the top of the side wall of the receiving base 2. When the receiving base 2 pops out, the limiting protrusion 12 will abut against the top of the side wall of the receiving base 2, thereby limiting the sliding range of the receiving base 2 and ensuring that the receiving base 2 will not exceed the range of the housing 1 when it pops out. The user can easily put his hand into the storage cavity 21 and directly take out the ink cartridge without being blocked by the side wall of the receiving base 2, which improves the efficiency and satisfaction of use.

[0034] More specifically, such as Figure 2 and Figure 3 As shown, the housing 1 includes a sleeve 13 and a base 14, which are detachably connected. The storage seat 2 is slidably connected to the sleeve 13, and the locking mechanism 4 is mounted on the base 14. This design divides the housing 1 into two main parts: the sleeve 13 and the base 14. The sleeve 13 primarily accommodates the storage seat 2 and provides a sliding track, while the base 14 is used to mount the locking mechanism 4 and provides support for the entire device. The detachable connection design of the sleeve 13 and the base 14 makes the assembly and maintenance of the entire device more convenient. Users can easily disassemble the sleeve 13 and the base 14 for cleaning or replacement of parts.

[0035] More specifically, such as Figure 2 and Figure 6 As shown, the base 14 is provided with a first mounting seat 141 adapted to the locking mechanism 4. The locking mechanism 4 is installed in the first mounting seat 141, and the first elastic member 5 is fitted on the outside of the first mounting seat 141. The first mounting seat 141 is added to the base 14. Its shape and size are designed to accommodate and fix the locking mechanism 4, ensuring the stable installation of the locking mechanism 4 in the base 14, providing precise positioning and support, reducing damage caused by external impact or vibration, and improving the operational reliability of the locking mechanism 4.

[0036] More specifically, such as Figures 2 to 4 , Figure 6As shown, the base 14 is provided with a second mounting seat 142 adapted to the first elastic member 5, and the bottom of the storage seat 2 is provided with a third mounting seat 26 adapted to the first elastic member 5. One end of the first elastic member 5 is located in the second mounting seat 142, and the other end of the first elastic member 5 is located in the third mounting seat 26. The base 14 is provided with the second mounting seat 142, the shape and size of which are designed to accommodate one end of the first elastic member 5. The bottom of the storage seat 2 is provided with the third mounting seat 26, the shape and size of which are designed to accommodate the other end of the first elastic member 5. Both the second mounting seat 142 and the third mounting seat 26 have a certain depth and shape to match the shape of the first elastic member 5, ensuring that it can be firmly installed between the storage seat 2 and the base 14, reducing the shaking or displacement of the first elastic member 5 during use, and improving the reliability of the entire device.

[0037] More specifically, such as Figure 2 and Figure 6 As shown, the outer wall of the sleeve 13 is provided with multiple third positioning protrusions 131, and the inner wall of the base 14 is provided with a locking groove 143 that matches the third positioning protrusions 131. The third positioning protrusions 131 and the locking groove 143 are elastically connected to lock the sleeve 13 to the base 14. The third positioning protrusion 131 is a protruding part on the outer wall of the sleeve 13 and has a certain elasticity. The inner wall of the base 14 is provided with a locking groove 143. The shape and size of the locking groove 143 match the third positioning protrusion 131 to ensure that when the sleeve 13 is inserted into the base 14, the third positioning protrusion 131 can smoothly enter the locking groove 143 and achieve elastic locking. The elastic deformation enables the sleeve 13 to engage or disengage from the slot 143, ensuring a reliable connection between the sleeve 13 and the base 14. This effectively prevents the sleeve 13 from accidentally loosening during normal use, ensuring the stability of the entire device. Furthermore, the elastic buckle design makes the assembly and disassembly of the sleeve 13 and the base 14 very convenient. Users only need to insert the sleeve 13 into the base 14, and the third positioning protrusion 131 will automatically engage with the slot 143 to complete the connection. When disassembling, only a certain amount of external force needs to be applied to disengage the third positioning protrusion 131 from the slot 143. When users need to clean or replace parts, they can easily disassemble the sleeve 13 and the base 14 for maintenance and then reassemble them. The operation is simple and quick.

[0038] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
