Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a quick-install and removable ink cartridge clip structure. Background Technology

[0002] In printers, the insertion and removal of ink cartridges from the printhead typically relies on a latch on the cartridge. Currently, the latch is usually integrated with the cartridge's base, achieved through the elastic deformation of the injection-molded material. Most products on the market use this elastic deformation method. Because the latch requires elastic deformation, the type of injection-molded material is limited; polypropylene is generally used, as other materials are brittle, prone to breakage and deformation. Furthermore, this type of elastically deformable plastic has a short lifespan, is prone to aging, and once the latch is damaged, it cannot be replaced, rendering the entire cartridge unusable, resulting in poor overall practicality.

[0003] To address this, utility model CN213920308U discloses a novel ink cartridge latch, comprising an ink cartridge body, a latch body two mounted on the side wall of the ink cartridge body, latch body two and the ink cartridge body hinged together by a positioning post two, and a latch body one mounted on the top wall of latch body two, latch body one and the ink cartridge body hinged together by the positioning post one. An elastic device is provided between latch body two and the ink cartridge body. During installation, the ink cartridge body is aligned with the guide groove of the printer, and then an upward force is applied to latch body one. When latch body two reaches the slot, no further force is applied to latch body one, allowing latch body two to latch into the slot within the print head through the elastic force of the elastic device. Therefore, this device has a simple structure, is easy to use, and has an extended service life. If the ink cartridge latch is damaged, only the latch body needs to be replaced, while the ink cartridge body remains intact and can continue to be used.

[0004] However, the existing technology has its shortcomings in use: the latch on the buckle is prone to wear after long-term use, which causes the ink cartridge and the print head to not be securely connected and thus easily fall off, affecting the ink transfer. The connection method between the buckle and the ink cartridge makes it difficult to replace the buckle quickly. Usually, the ink cartridge shell needs to be disassembled for replacement, which is not only time-consuming but also easily damages the internal structure of the ink cartridge.

[0005] Therefore, this utility model provides a cartridge clip structure that can be quickly installed and disassembled. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-install and quick-remove ink cartridge clip structure to solve the problems mentioned in the background. This utility model has the advantage of making clip replacement more convenient and reducing the cost of clip replacement.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-installing and disassembling ink cartridge buckle structure, including an ink cartridge body, a positioning groove provided on the bottom wall of the ink cartridge body, a front pressure plate and a rear pressure plate placed in the positioning groove, one end of the rear pressure plate resting on the upper part of one end of the front pressure plate, a support spring provided in the positioning groove located below one end of the front pressure plate, an axially extendable column and a control assembly for controlling the extension and retraction of the column provided on both the front and rear pressure plates, and positioning sleeves fixedly connected to both sides of the positioning groove and inserted into and rotatably engaged with the two ends of the column.

[0008] Furthermore, the column includes an outer tube and positioning shafts fitted at both ends of the outer tube. The positioning shafts and the outer tube are slidably connected. One end of the positioning shaft is clearance-fitted with an adjacent positioning sleeve. Connecting sleeves fitted outside the outer tube are fixedly connected to the bodies of the front pressure plate and the rear pressure plate.

[0009] Furthermore, the control assembly includes a connecting shaft, a magnet, and a magnetic suction plate. The magnet and the magnetic suction plate are respectively fixedly mounted on opposite ends of two positioning shafts inside the outer sleeve. The outer sleeve contains a rod with an elliptical cross-section located between the magnet and the magnetic suction plate. The connecting shaft is installed through the bottom wall of the outer sleeve and the two are rotatably connected. The middle part of one end of the rod is fixedly connected to one end of the connecting shaft. The other end of the connecting shaft has a drive groove. The bottom wall of the connecting sleeve has a notch opposite to the drive groove.

[0010] Furthermore, one side of the magnetic suction plate is provided with an arc-shaped groove that is adapted to the rod body.

[0011] Furthermore, the drive slot is a single-slot slot.

[0012] Furthermore, the outer wall of the outer sleeve is provided with a countersunk hole that is rotatably connected to the connecting shaft, the drive groove is located in the countersunk hole, the outer sleeve and the connecting sleeve are clearance-fitted, and the outer sleeve can be moved out of the connecting sleeve when it moves axially.

[0013] Furthermore, the inner peripheral wall of the connecting sleeve is provided with a sliding groove, and the outer peripheral wall of the outer sleeve is fixedly connected with a limiting block located in the sliding groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, retractable columns are provided on both the front and rear pressure plates. When the columns are extended, they enter the positioning slots of the ink cartridge body and are fixedly installed in the positioning sleeves. When the columns are retracted, they can detach from the positioning sleeves. This retractable column structure makes it more convenient to replace the front and rear pressure plates through the positioning slots without disassembling the ink cartridge body.

[0016] 2. In this utility model, the column includes an outer tube and positioning shafts located at both ends of the outer tube. The positioning shafts and the outer tube are axially slidably connected. A control assembly consisting of a magnet, a magnetic block, a connecting shaft, and a rod is provided to control the axial movement of the positioning shaft relative to the outer tube. This makes the extension and retraction control of the entire column more convenient, while reducing the space occupied by the column and the control assembly, making it suitable for use with small ink cartridges.

[0017] 3. In this utility model, both the front pressure plate and the rear pressure plate are fixedly connected to the connecting sleeves sleeved on the outer sleeve. The connecting sleeves and the positioning tube can slide axially and separate. Therefore, if the latch on the front pressure plate is damaged or the rear pressure plate is broken, the front pressure plate and the rear pressure plate can be replaced separately without replacing the column and control assembly, which has the advantage of reducing replacement costs.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a quick-installation and disassembly ink cartridge buckle structure, including an ink cartridge body 1. A positioning groove 11 is formed on the bottom wall of the ink cartridge body 1. Support plates are fixedly connected to the bottom of both sides of the positioning groove 11. A front pressure plate 2 and a rear pressure plate 3 are placed inside the positioning groove 11. The width of the space between the two support plates is greater than or equal to the width of the front pressure plate 2 and the rear pressure plate 3. One end of the rear pressure plate 3 rests on the upper part of one end of the front pressure plate 2. A latch is fixedly connected to the other end of the front pressure plate 2. The rear pressure plate 3 serves as a trigger plate. A support spring 4 is provided in the positioning groove 11, located below one end of the front pressure plate 2. The bottom end of the support spring 4 abuts against the upper surfaces of the two support plates. Both the front pressure plate 2 and the rear pressure plate 3 are provided with axially extendable columns 5 and controls for the extension of the columns 5. The control assembly for shrinkage has positioning sleeves 111 fixedly connected to both sides of the positioning groove 11 and rotatably engaged with the two ends of the column 5. Specifically, the column 5 includes an outer tube 51 and positioning shafts 52 sleeved at both ends of the outer tube 51. The positioning shafts 52 and the outer tube 51 are slidably connected. One end of the positioning shaft 52 is clearance-fitted with the adjacent positioning sleeve 111. Connecting sleeves 6 sleeved outside the outer tube 51 are fixedly connected to the plates of the front pressure plate 2 and the rear pressure plate 3. Under the restriction of the positioning sleeves 111, the front pressure plate 2 and the rear pressure plate 3 will rotate up and down around the column 5. When in use, when the free end of the rear pressure plate 3 is lifted, the free end of the rear pressure plate 3 will press down on one end of the front pressure plate 2. At this time, the support spring 4 is compressed, and the front pressure plate 2 drives the latch on it to move upward. The retractable structure of the aforementioned column 5 allows it to detach from the positioning sleeve 111. At this point, the front pressure plate 2, the rear pressure plate 3, and the column 5 can be removed from the opening of the positioning groove 11. This design significantly reduces the difficulty of replacing the snap-fit ​​structure formed by the front pressure plate 2, the rear pressure plate 3, and the column 5. The aforementioned control assembly is a transmission structure for manually controlling the extension and retraction of the column 5.

[0027] Specifically, the control assembly includes a connecting shaft 7, a magnet 8, and a magnetic suction plate 9. The magnet 8 and the magnetic suction plate 9 are respectively fixedly installed on the opposite ends of two positioning shafts 52 inside the outer sleeve 51. The outer sleeve 51 contains a rod 71 with an elliptical cross-section located between the magnet 8 and the magnetic suction plate 9. The magnetic attraction between the magnet 8 and the magnetic suction plate 9 causes them to adhere tightly to the outer wall of the rod 71. The connecting shaft 7 is installed through the bottom wall of the outer sleeve 51 and is rotatably connected to the rod. The middle of one end of the rod 71 is fixedly connected to one end of the connecting shaft 7. When the connecting shaft 7 rotates, it can drive the rod 71 to rotate. The rod 71 can push the two connecting shafts 7 to move synchronously but in different directions using its elliptical outer surface. The other end of the connecting shaft 7 is provided with a drive groove 72. Preferably, the drive groove 72 is a slot. The bottom wall of the connecting sleeve 6 is provided with a notch 61 opposite to the drive groove 72. When it is necessary to rotate the connecting shaft 7, a flathead screwdriver is inserted into the drive groove 72 and then screwed to control the synchronous but in different directions of the two connecting shafts 7. This control combination structure makes the extension and retraction control of column 5 more convenient.

[0028] The inner peripheral wall of the connecting sleeve 6 is provided with a groove 63, and the outer peripheral wall of the outer sleeve 51 is fixedly connected with a limiting block 512 located in the groove 63. The arrangement of the groove 63 and the limiting block 512 ensures that the outer sleeve 51 can only move axially relative to the connecting sleeve 6. This arrangement ensures that the notch 61 and the drive groove 72 are aligned.

[0029] The magnetic plate 9 has an arc-shaped groove 91 on one side that is adapted to the rod 71. The function of the arc-shaped groove 91 is to prevent slipping. Specifically, the outer wall corresponding to the long side of the rod 71 enters the arc-shaped groove 91. The arc-shaped groove 91 can effectively prevent the rod 71 from rotating freely.

[0030] In this embodiment, the outer wall of the outer sleeve 51 is provided with a countersunk hole 511 that is rotatably connected to the connecting shaft 7. The drive groove 72 is located in the countersunk hole 511. The countersunk hole 511 has the function of hiding the drive groove 72. The outer sleeve 51 and the connecting sleeve 6 are in clearance fit. When the outer sleeve 51 moves axially, it can move out of the connecting sleeve 6. That is to say, after the outer sleeve 51 slides out of the connecting sleeve 6, the entire column 5 and the control assembly will be completely separated from the corresponding front pressure plate 2 and rear pressure plate 3. When replacing the buckle structure, only the front pressure plate 2 and / or the rear pressure plate 3 need to be replaced.

[0031] Working principle: When installing the ink cartridge body 1, directly align the ink cartridge body 1 with the guide groove of the printer, then apply an upward force to the free end of the rear pressure plate 3, and then push the ink cartridge body 1 forward. After the latch on the front pressure plate 2 reaches the slot, no more force is applied to the rear pressure plate 3. The front pressure plate 2 uses the elastic power of the support spring 4 to make the latch engage with the slot in the print head, thus completing the assembly of the ink cartridge body 1 and the printer. When the latch is worn or the front pressure plate 2 or rear pressure plate 3 is broken, first remove the ink cartridge body 1. Use a flathead screwdriver to insert into the drive slot 72 and turn it 90 degrees. The connecting shaft 7 drives the rod 71 to rotate and pushes the positioning shafts 52 on both sides. Under the mutual attraction of the magnet 8 and the magnetic suction plate 9, the two positioning shafts 52 move in opposite directions and simultaneously disengage from the positioning sleeve 111 in the positioning slot 11. At this time, the corresponding front pressure plate 2 or rear pressure plate 3, as well as the column 5 and control assembly on both, can be removed from the opening of the positioning slot 11. After removal, axially push the column 5 to disengage it and the control assembly from the connecting sleeve 6. Then replace the damaged front pressure plate 2 or rear pressure plate 3. After replacement, reverse the removal steps of the front pressure plate 2 or rear pressure plate 3 so that the two positioning shafts 52 and the positioning sleeve 111 in the positioning slot 11 can be reconnected.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
