Description

Technical Field

[0001] This utility model relates to the field of ink cartridge technology, and in particular to a precision assembly and positioning structure for regenerated ink cartridges. Background Technology

[0002] Ink cartridges are among the fastest-consumed components in printing equipment. To save costs and protect the environment, the recycling of remanufactured ink cartridges has become a common practice in the industry. The manufacturing process of remanufactured ink cartridges includes disassembling, cleaning, ink filling, and finally reassembling the waste cartridges.

[0003] In this reassembly process, the assembly of the cartridge body and the lid is a crucial step. This assembly step not only affects the structural stability of the ink cartridge but also directly determines its sealing performance to prevent internal ink leakage during transportation or use.

[0004] In the existing technology, the connection between the cartridge body and the cover of the regenerated ink cartridge is mostly achieved by a simple snap-fit ​​structure or conventional bolt fixing. Although the simple snap-fit ​​structure is quick to assemble, it is prone to wear after repeated disassembly and assembly, which can cause the snap-fit ​​to loosen and create a gap between the cartridge body and the cover, seriously affecting the assembly precision and sealing effect.

[0005] While conventional bolt fixing offers high connection strength, it's difficult to guarantee the precise relative position between the cartridge cover and body during tightening, resulting in low positioning accuracy and a relatively cumbersome assembly process. Therefore, existing assembly methods generally suffer from inaccurate positioning, poor structural stability, and a tendency to loosen over long-term use, failing to meet the high-precision assembly and reliable sealing requirements of regenerated ink cartridges.

[0006] Therefore, this utility model proposes a precision assembly and positioning structure for regenerated ink cartridges to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of insufficient positioning, unstable connection, poor sealing, and easy loosening and ink leakage after repeated disassembly and assembly in the existing assembly structure for regenerated ink cartridges, this utility model aims to provide a precision assembly and positioning structure for regenerated ink cartridges with improved structure that can effectively solve the above problems.

[0008] This utility model provides a precision assembly and positioning structure for regenerated ink cartridges, including: a cartridge body and a positioning mechanism disposed on the cartridge body.

[0009] The top of the cartridge has an opening for filling with ink, and the side wall of the cartridge is connected to an ink outlet.

[0010] The positioning mechanism includes a lid, which is detachably placed over the opening of the box. The bottom of the lid has an integrally formed sliding plate extending along its length. The top inner wall of the box has a groove that slides with the sliding plate. The box has a slot near the end of the groove.

[0011] The positioning mechanism also includes a hollow short block fixed to the side wall of the box cover. A locking post is slidably disposed inside the hollow short block. One end of the locking post can extend out of the hollow short block and elastically engage with the locking groove. A V-shaped spring is also disposed inside the hollow short block. The V-shaped spring elastically abuts against the inner wall of the hollow short block and the other end of the locking post to drive the locking post to reset.

[0012] The positioning mechanism also includes fixing bolts, which pass through the pre-set through holes of the lid and are threaded to the box body to fasten the lid to the box body. This structure, which combines sliding guidance, elastic locking and bolt locking, ensures the ease of assembly of the box body and lid, the accuracy of positioning and the long-term stability of the connection.

[0013] Preferably, the structure also includes a protective mechanism disposed on the cartridge body, which is used to selectively seal the ink outlet when the regenerated ink cartridge is not in use.

[0014] Preferably, the protective mechanism includes a rotating plate, which is rotatably connected to the cartridge body near the ink outlet groove. A square flexible pad is fixedly connected to the rotating plate, and a connector block is fixedly connected to the cartridge body. The connector block is arranged around the ink outlet groove and has a groove for tightly fitting with the square flexible pad through flexible deformation.

[0015] Preferably, a grooved plate is integrally formed at the end of the rotating plate away from the square flexible pad, and a corresponding placement slot is provided on the cartridge body. The placement slot is used to store the grooved plate when the ink outlet is in the open state, so as to avoid the protective mechanism from interfering with the use of the ink cartridge.

[0016] Preferably, the protective mechanism further includes a hollow block and a spring-loaded rod. The hollow block is fixed to the side wall of the box and adjacent to the placement slot. The spring-loaded rod is slidably disposed inside the hollow block and can extend under its elastic force to abut against and fix the grooved plate stored in the placement slot, preventing it from shaking during use.

[0017] Preferably, the cross-sectional shape of the slide plate and the cross-sectional shape of the slide groove are mutually compatible trapezoidal structures. This structural design provides vertical limiting while sliding, preventing the cover from tilting or coming off before the fixing bolts are tightened.

[0018] Preferably, the square flexible gasket is made of silicone rubber or thermoplastic elastomer material, which has good elasticity and ink corrosion resistance, ensuring the reliability and durability of the seal.

[0019] Preferably, the protruding end of the locking post is provided with a guide slope, and the entrance of the locking slot is provided with a mating slope. This design allows the locking post to be automatically guided and compressed when the lid slides into place, and then smoothly springs into the locking slot after it is in place, achieving quick and automatic locking and simplifying the assembly operation.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problems of inaccurate positioning, cumbersome operation, unstable connection, and easy loosening in the assembly of regenerated ink cartridge bodies and covers in the prior art by setting a positioning mechanism that combines sliding guide of the slide plate and slide groove, elastic locking of the locking post and the locking groove, and final locking of the fixing bolt. It achieves the technical effect of rapid assembly, accurate positioning, and long-term use without loosening, and significantly improves the assembly accuracy, structural stability and sealing performance of regenerated ink cartridges.

[0021] 2. This utility model, by setting a rotatable rotating plate and using the rotating plate to drive a square flexible pad to selectively seal the ink outlet tank, solves the problem in the prior art of ink leakage, waste, and pollution of the equipment environment caused by the exposed ink outlet tank when the regenerated ink cartridge is not in use. It achieves the technical effect of effectively preventing ink leakage, reducing waste, and keeping the equipment clean and safe.

[0022] 3. This utility model integrates a precise positioning mechanism with a clever protective mechanism, and designs a storage structure for the protective mechanism that does not affect its use. This solves the problems of single function and inadequate structural design in the prior art, and achieves the technical effect of compact structure, complete function, convenient operation and user-friendliness, thus comprehensively improving the practicality and user experience of regenerated ink cartridge products.

Detailed Implementation

[0025] 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. Example

[0026] Please refer to Figures 1 to 4 This utility model provides a precision assembly and positioning structure for regenerated ink cartridges, which aims to solve the problems in the prior art such as inaccurate assembly and positioning of the regenerated ink cartridge body 1 and the cover 201, unstable connection, poor sealing and risk of ink leakage.

[0027] like Figure 1 and Figure 2 As shown, a precision assembly and positioning structure for regenerated ink cartridges includes a cartridge body 1 and a positioning mechanism 2 detachably mounted on the cartridge body 1. The top of the cartridge body 1 has an opening for filling ink, and an ink outlet groove 4 is connected to the side wall of the cartridge body 1. The positioning mechanism 2 is designed to achieve a precise seal and secure fixation of the opening of the cartridge body 1.

[0028] Specifically, the positioning mechanism 2 includes a lid 201, which is used to cover the opening of the box body 1. The bottom of the lid 201 is integrally formed with a sliding plate 202 extending along its length. In order to achieve guidance and initial positioning, a groove 204 is provided on the inner wall of the top of the box body 1 to slide and cooperate with the sliding plate 202. The cross-sectional shape of the sliding plate 202 and the cross-sectional shape of the groove 204 are trapezoidal structures that are adapted to each other. During assembly, the sliding connection between the sliding plate 202 and the groove 204 not only achieves precise guidance for the installation process of the lid 201, but also prevents the lid 201 from detaching upwards during use by utilizing the cooperation of the trapezoidal structure.

[0029] To further achieve rapid positioning and locking, a slot 203 is provided on the box body 1 near the end of the slide groove 204. In conjunction with this, the positioning mechanism 2 also includes a hollow short block 207 fixed to the side wall of the box cover 201. A locking post 205 is slidably disposed within the hollow short block 207. One end of the locking post 205 can extend out of the hollow short block 207 and elastically engage with the slot 203, thereby completing rapid pre-positioning. A V-shaped spring piece 206 is also provided inside the hollow short block 207. The 6 elastically abuts against the inner wall of the hollow short block 207 and the other end of the locking post 205, providing a continuous pop-out driving force for the locking post 205; in order to make the locking process smoother, the protruding end of the locking post 205 is provided with a guiding slope, and the entrance of the slot 203 is provided with a mating slope. When the slide plate 202 slides in along the slide groove 204, the two slopes contact and engage, guiding the locking post 205 to automatically compress until it slides into place. Then, the locking post 205 automatically pops into the slot 203 under the action of the V-shaped spring piece 206.

[0030] Finally, to ensure stability and sealing during long-term use and to prevent loosening due to vibration or aging, the positioning mechanism 2 also includes fixing bolts 208. The fixing bolts 208 pass through the preset through holes of the cover 201 and are threadedly connected to the box body 1. By tightening the fixing bolts 208, the cover 201 and the box body 1 are finally fastened and locked, thereby completely eliminating the assembly gap between the two and achieving the effect of precise positioning and no loosening during long-term use.

[0031] Please refer to Figure 1 and Figure 4 The protective mechanism 3 includes a rotating plate 303, which is rotatably connected to the housing 1 near the ink outlet 4. A square flexible pad 302 is fixedly connected to one end of the rotating plate 303. The square flexible pad 302 is made of silicone rubber or thermoplastic elastomer to ensure the flexible deformation capability required for sealing. Correspondingly, a connector block 301 is fixedly connected to the housing 1. The connector block 301 is arranged around the ink outlet 4 and has a groove for tightly fitting with the square flexible pad 302 through flexible deformation. When it is necessary to seal the ink outlet 4, the rotating plate 303 is rotated, which can drive the square flexible pad 302 to be tightly pressed into the groove of the connector block 301. The flexible deformation of the pad achieves a reliable seal on the ink outlet 4, thereby effectively preventing ink leakage when not in use.

[0032] To prevent interference with the protective mechanism 3 when not in use, a grooved plate 304 is integrally formed on the end of the rotating plate 303 away from the square flexible pad 302. Correspondingly, a placement slot 305 is provided on the cartridge body 1 to accommodate the grooved plate 304 when the ink outlet 4 is in the open state. When the rotating plate 303 is pushed upward to open the ink outlet 4, the grooved plate 304 will swing and be stored in the placement slot 305. This structural design ensures that the protective mechanism 3 is compact in the non-working state and does not affect the normal installation and use of the ink cartridge.

[0033] In a preferred embodiment, to reliably secure the protective mechanism 3 when it is stored, the protective mechanism 3 further includes a hollow elongated block 307 and a spring-loaded pull rod 306. The hollow elongated block 307 is fixed to the side wall of the cartridge body 1 and adjacent to the placement slot 305. The spring-loaded pull rod 306 is slidably disposed in the hollow elongated block 307 and can extend under its elastic force to abut against and secure the grooved plate 304 stored in the placement slot 305. This structure can effectively prevent the grooved plate 304 from shaking or accidentally moving out when stored, ensuring the stability of the ink cartridge during use.

[0034] As another preferred embodiment, in order to enhance the stability and limiting effect of the lid 201 and the box body 1 during the sliding process, the cross-sectional shape of the slide plate 202 and the cross-sectional shape of the slide groove 204 are mutually adapted trapezoidal structures. This dovetail-like matching method can effectively resist vertical separation force while providing smooth sliding guidance, thus providing reliable vertical limiting for the lid 201 before the fixing bolt 208 is tightened.

[0035] As another preferred embodiment, in order to enable the locking post 205 to automatically and smoothly engage in the slot 203, the protruding end of the locking post 205 is provided with a guide slope, and the entrance of the slot 203 is provided with a mating slope. In the final stage of the slide plate 202 sliding into the slide groove 204, the guide slope of the locking post 205 contacts and interacts with the mating slope of the slot 203, forcing the locking post 205 to overcome the elasticity of the V-shaped spring 206 and retract. When the slide plate 202 slides into place, the locking post 205 immediately aligns with the slot 203 and automatically springs in, achieving unobstructed and rapid locking.

[0036] As another preferred embodiment, in order to ensure the reliability and durability of the protective mechanism 3 sealing the ink outlet 4, the square flexible pad 302 is made of silicone rubber or thermoplastic elastomer. Such materials have excellent elasticity and resistance to ink corrosion, which can ensure that they can still fit tightly with the groove of the connector block 301 after multiple uses, forming an effective sealing interface.

[0037] Working principle: When using the positioning mechanism 2, first insert the sliding plate 202 at the bottom of the cover 201 on the upper part of the cartridge 1 into the sliding groove 204 of the cartridge 1. After insertion to the bottom, release the V-shaped spring 206 in the hollow short block 207. The V-shaped spring 206 restores its elasticity and pushes the locking post 205 into the locking groove 203 to achieve rapid positioning and assembly. Finally, tighten the fixing bolt 208 to reinforce it. This achieves a precision assembly and positioning effect between the cartridge 1 and the cover 201, which is fast assembly without deviation, precise positioning without gaps, and long-term use without loosening. This can adapt to scenarios where regenerated ink cartridges have requirements for component assembly accuracy, sealing and structural stability. When using the protective mechanism 3, rotating the rotating plate 303 causes the square flexible pad 302 to rotate. The square flexible pad 302 will lock into the groove of the connector block 301 through its own flexible deformation, sealing the ink outlet 4 to prevent the internal ink from flowing out when not in use. When needed, the rotating plate 303 is pushed upward to drive the groove plate 304 into the placement slot 305. Then, the elastic lever 306 inside the hollow long block 307 is released and springs back into the storage without affecting subsequent use. This effectively avoids ink leakage when not in use, reduces ink waste, and avoids pollution to the surrounding environment caused by ink leakage, creating a clean and safe operating environment for the equipment.
