Description

Fountain pen ink cartridges with floating seals Technical Field

[0001] This utility model relates to the field of pen accessories technology, specifically a fountain pen ink cartridge with a floating sealing ring. Background Technology

[0002] The ink cartridge of a fountain pen is the part of the pen used to hold ink, also called the ink sac. The ink sac draws ink through negative pressure, and the ink slowly seeps into the ink cartridge to meet the needs of writing.

[0003] However, existing ink cartridges only have the function of drawing and storing ink. When there is a lot of ink in the ink cartridge, the weight of the ink is also greater. At this time, the ink will seep down faster, resulting in more ink seeping out when writing with a fountain pen, causing the lines of the writing to be thicker, or even the ink to soak the paper. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model proposes an ink cartridge for fountain pens with a floating sealing ring, which can slow down the rate of ink seepage, so that when there is a large amount of ink, the writing lines are not too thick and the ink does not wet the paper during the writing process.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a fountain pen ink cartridge with a floating sealing ring, comprising a shell, a threaded tube fixedly connected to the bottom of the shell, rubber gaskets fixedly connected to both sides of the shell, a sealing assembly provided inside the shell, the sealing assembly comprising a sealing ring, a lifting block, a sliding piece and a groove, the sealing ring being slidably connected to the inner wall of the shell, the lifting block being fixedly connected to the sealing ring, two grooves being formed on the lifting block, two sliding pieces being slidably connected to the interior of the two grooves respectively, and an auxiliary assembly provided inside the shell, the auxiliary assembly comprising a through hole formed on the lifting block.

[0006] Preferably, the sealing assembly further includes fixing rods, two of which are fixedly connected to the inner wall of the housing, and two sliding plates are slidably connected to the two fixing rods.

[0007] Preferably, the sealing assembly further includes a base rod and springs, the base rod being fixedly connected to the inner wall of the housing, and the two springs being fixedly connected between the lifting block and the base rod.

[0008] Preferably, the auxiliary component further includes a vertical rod and a disc, the vertical rod being fixedly connected to the base rod, and the disc being fixedly connected to the vertical rod.

[0009] Preferably, the auxiliary component further includes a sponge ring and a bottom hole, the sponge ring being fixedly connected to the disk, and the bottom hole being formed on the disk.

[0010] Preferably, the grooves are symmetrically arranged on the lifting block, and the inner wall of the groove is inclined.

[0011] Compared with existing technologies, the significant advantages of this invention are:

[0012] Firstly, in this invention, the ink cartridge and the inside of the pen are connected by a threaded tube. When ink needs to be drawn, the two rubber pads are squeezed. When the two rubber pads are squeezed, they press against the two sliders. The two sliders move together and move towards the center. Since the two sliders slide in the two grooves respectively, the movement of the sliders will cause the lifting block to move downward. When the lifting block moves downward, the through hole that was originally blocked by the disc will be exposed. Therefore, squeezing the rubber pads can allow air to be discharged through the through hole. Then, the rubber pads are released, and the spring force causes the lifting block to rise. At the same time, the rubber pads return to their original position due to their own elasticity. At this time, the negative pressure inside the shell will cause the ink to be drawn into the shell. Some of the ink is located below the lifting block, while the excess ink is located above the lifting block.

[0013] Secondly, in this utility model, when the ink is drawn into the outer shell, when using the pen, the ink located below the lifting block will seep out through the pen tip for writing. Since there is less ink below the lifting block, the gravity inside the ink is smaller, which can prevent excessive ink leakage. The ink located above the lifting block will drip slowly downward through the sponge ring and the bottom hole, thereby slowly replenishing the ink below.

[0014] This solves the problem that existing fountain pen ink cartridges tend to leak ink too quickly when there is a large amount of ink. Attached Figure Description

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved ink cartridge for fountain pens with a floating sealing ring. The technical solution of this utility model is as follows:

[0023] As shown in Figures 1-3, a fountain pen ink cartridge with a floating sealing ring includes a housing 1. A threaded tube 2 is fixedly connected to the bottom of the housing 1, and rubber pads 3 are fixedly connected to both sides of the housing 1. A sealing component 4 is provided inside the housing 1. The sealing component 4 includes a sealing ring 41, a lifting block 42, a sliding piece 44, and a groove 45. The sealing ring 41 is slidably connected to the inner wall of the housing 1 and is made of rubber. The lifting block 42 is fixedly connected to the sealing ring 41. Two grooves 45 are formed on the lifting block 42, and two sliding pieces 44 are slidably connected to the inside of the two grooves 45 respectively. The two sliding pieces 44 are symmetrically arranged inside the housing 1. When the rubber pads 3 are squeezed, they can further press against the sliding pieces 44. An auxiliary component 5 is provided inside the housing 1. The auxiliary component 5 includes a through hole 51, which is formed on the lifting block 42.

[0024] Furthermore, as shown in Figures 2 and 3, the sealing assembly 4 also includes two fixing rods 43, which are fixedly connected to the inner wall of the housing 1. The cross-section of the two fixing rods 43 is circular, and the two sliding pieces 44 are slidably connected to the two fixing rods 43.

[0025] Furthermore, as shown in Figures 2 and 3, the sealing assembly 4 also includes a bottom rod 46 and springs 47. The bottom rod 46 is fixedly connected to the inner wall of the housing 1 and is located at the bottom inside the housing 1. Two springs 47 are fixedly connected between the lifting block 42 and the bottom rod 46, and the two springs 47 are located on both sides of it.

[0026] Furthermore, as shown in Figures 2 and 3, the auxiliary component 5 also includes a vertical rod 52 and a disc 53. The vertical rod 52 is fixedly connected to the bottom rod 46 and passes through the through hole 51. The diameter of the vertical rod 52 is relatively small. The disc 53 is fixedly connected to the vertical rod 52 and can block the through hole 51, preventing the ink above the lifting block 42 from dripping down through the through hole 51.

[0027] Furthermore, as shown in Figures 2 and 3, the auxiliary component 5 also includes a sponge ring 54 and a bottom hole 55. The sponge ring 54 is fixedly connected to the disc 53 and surrounds the inside of the disc 53, so that the ink above the lifting block 42 can only wet the sponge ring 54 first, and then drip down through the bottom hole 55. The bottom hole 55 is opened on the disc 53 and is located at the bottom of the disc 53. The ink will enter the through hole 51 through the bottom hole 55 and then drip down below the lifting block 42.

[0028] Furthermore, as shown in Figure 2, grooves 45 are symmetrically arranged on the lifting block 42. The inner wall of the groove 45 is inclined. The bottom end of the slider 44 slides on the bottom wall of the groove 45. Therefore, when the slider 44 moves, the lifting block 42 can move up and down to complete the ink extraction and separate the ink through the lifting block 42 to avoid excessive ink and rapid mode seepage.

[0029] The specific working method is as follows: First, the ink cartridge and the inside of the pen are connected through the threaded tube 2. When ink needs to be drawn, the two rubber pads 3 are squeezed. When the two rubber pads 3 are squeezed, they press against the two sliders 44. The two sliders 44 move together and move towards the center. Since the two sliders 44 slide in the two grooves 45 respectively, the movement of the sliders 44 will cause the lifting block 42 to move downward. When the lifting block 42 moves downward, it will drive the sealing ring 41 to slide up and down inside the outer shell 1. The through hole 51, which was originally blocked by the disc 53, will be exposed at this time. Therefore, squeezing the rubber pads 3 can allow air to be discharged through the through hole 51. Then, the rubber pads 3 are released, and the spring 4... The elasticity of 7 causes the lifting block 42 to rise, while the rubber pad 3 returns to its original position due to its own elasticity. At this time, the negative pressure inside the outer shell 1 causes the ink to be drawn into the outer shell 1. Some of the ink is located below the lifting block 42, while the excess ink is located above the lifting block 42. After the ink is drawn into the outer shell 1, when using the pen, the ink located below the lifting block 42 will seep out through the pen tip for writing. Since there is less ink below the lifting block 42, the gravity inside the ink is smaller, which can prevent excessive ink seepage. The ink located above the lifting block 42 will slowly drip down through the sponge ring 54 and the bottom hole 55, thus slowly replenishing the ink below.

Matters not covered in this utility model are common knowledge to those skilled in the art.
