Description

Technical Field

[0001] This utility model relates to the field of ink absorber technology, specifically a telescopic ink absorber. Background Technology

[0002] Fountain pens are loved by many users for their unique writing effect. When using a fountain pen, the ink needed is usually stored in a bottle. At this time, an ink converter is needed to draw out the ink. An ink converter, also known as an ink exchanger, uses mechanical operation to lower the internal air pressure, thereby drawing the ink up.

[0003] For example, a Chinese patent application (CN202021332146.3) discloses an ink absorber comprising a connector body, an ink absorber body, a first connecting tube, a needle tube, a connector, a limiting member, anti-slip texture, a second connecting tube, a limiting protrusion, a limiting hole, and an ink absorber body. The ink absorber body includes the connector body and the ink absorber body. The connector body includes a second connecting tube and a limiting protrusion. The bottom end of the second connecting tube is inserted into the first connecting tube through the limiting hole, and the limiting protrusion extends into the limiting hole, thereby limiting the position of the second connecting tube and preventing it from detaching from the limiting member during ink absorption, ensuring stability during the ink absorption process. Furthermore, the bottom end of the needle is placed in the ink to achieve ink absorption. The operation is simple and does not easily soil the user's hands or clothing. The anti-slip texture is designed to prevent the user from slipping when holding the connector.

[0004] However, in actual use, if the needles in the above-mentioned device are not put away in time after use, users are prone to being pricked and injured, which reduces the safety of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a telescopic ink absorber. By pulling the lifting plate, two push-pull rods are pulled to pull the limiting plate, causing the ink-absorbing needle tube to retract into the outer cylinder for storage. This facilitates timely retraction of the ink-absorbing needle tube, thereby preventing the ink-absorbing needle tube from being located outside the outer cylinder after ink absorption and potentially injuring the user. This improves the safety of this utility model and effectively solves the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a telescopic ink absorber, including an outer cylinder, a threaded base connected to the outer wall of the bottom end of the outer cylinder by a thread, and an ink-absorbing needle tube provided at the bottom end of the inner part of the threaded base;

[0007] The outer cylinder is equipped with a shrinkage assembly for driving the ink-absorbing needle tube to shrink;

[0008] The top of the outer cylinder is equipped with an ink-absorbing component for absorbing ink;

[0009] The shrinking assembly includes a limiting plate, which is located at the top inside the threaded base. Limiting blocks are fixedly provided on both sides of the limiting plate. Sliding grooves are opened on both sides inside the outer cylinder. The limiting blocks are slidably disposed in the sliding grooves, which facilitates the lifting and lowering of the limiting blocks along the sliding grooves to limit the limiting plate. Push-pull rods are fixedly provided on both sides of the top of the limiting plate, which facilitates the movement of the push-pull rods to drive the limiting plate to move and store the limiting plate inside the top of the outer cylinder.

[0010] Preferably, the top of the outer cylinder has a slot, the top of the slot has a lifting plate, the top of the push-pull rod passes through the top of the outer cylinder and the slot, the top of the push-pull rod is fixedly located at the bottom of the lifting plate, the ink-absorbing needle is fixedly located inside the limiting plate, and the ink-absorbing needle, the limiting plate and the inside of the outer cylinder are interconnected to facilitate ink absorption through the ink-absorbing needle.

[0011] Preferably, the ink-absorbing assembly includes a piston plate, which is disposed on the top of the limiting plate. Slider blocks are fixedly provided on both sides of the piston plate. The sliders are slidably disposed inside the slide groove, which facilitates the lifting and lowering of the piston plate and drives the two sliders to lift and lower along the two slide grooves respectively, thereby limiting the movement of the piston plate.

[0012] Preferably, a pressing rod is fixedly provided on the top of the piston plate, the top end of the pressing rod penetrates through the top of the outer cylinder, and a handle is fixedly provided on the top end of the pressing rod. The handle is located at the top of the slot, which facilitates pulling the handle to drive the pressing rod and the piston plate to rise and fall inside the outer cylinder to realize the ink absorption function.

[0013] Preferably, a spring is sleeved on the outside of the pressing rod, and the top and bottom ends of the spring are fixedly connected to the bottom of the handle and the bottom of the slot, respectively, so as to facilitate pulling the handle to drive the pressing rod to rise and fall, and at the same time drive the spring to stretch or contract.

[0014] Preferably, the two push-pull rods are respectively located on both sides of the pressing rod, and the two push-pull rods pass through both sides of the piston plate, so that the push-pull rods can pass through the piston plate and realize movement.

[0015] Compared with the prior art, this utility model provides a telescopic ink converter, which has the following beneficial effects:

[0016] This invention uses a pull-out lifting disc to drive two push-pull rods to pull out the limiting disc, causing the limiting disc to be pulled out from the threaded base. This causes two limiting blocks to slide and rise along two sliding grooves, limiting the movement of the limiting disc. At the same time, the ink-absorbing needle tube is retracted into the outer cylinder for storage, thus preventing the ink-absorbing needle tube from being outside the outer cylinder after ink absorption and accidentally injuring the user. It also facilitates timely retraction and storage of the ink-absorbing needle tube, improving the safety of this invention. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6 As shown, this utility model provides a telescopic ink absorber, including an outer cylinder 1. The outer wall of the bottom end of the outer cylinder 1 is connected to a threaded base 5 by a thread. The bottom end of the threaded base 5 is provided with an ink-absorbing needle tube 6.

[0027] like Figure 1-4 As shown, the outer cylinder 1 is provided with a shrinking assembly 3 for driving the ink-absorbing needle tube 6 to shrink. The shrinking assembly 3 includes a limiting plate 31, which is located at the top of the threaded base 5. Limiting blocks 32 are fixed on both sides of the limiting plate 31. Sliding grooves 7 are opened on both sides of the inner side of the outer cylinder 1. The limiting blocks 32 are slidably disposed in the sliding grooves 7, so that the limiting blocks 32 can rise and fall along the sliding grooves 7 to limit the limiting plate 31. Push-pull rods 33 are fixed on both sides of the top of the limiting plate 31, so that the push-pull rods 33 can move to drive the limiting plate 31 to move.

[0028] The limiting plate 31 is stored inside the top of the outer cylinder 1. The top of the outer cylinder 1 has a slot 2, and the top of the slot 2 has a lifting plate 34. The top of the push-pull rod 33 passes through the top of the outer cylinder 1 and the slot 2. The top of the push-pull rod 33 is fixedly set at the bottom of the lifting plate 34. The ink-absorbing needle tube 6 is fixedly set inside the limiting plate 31, and the ink-absorbing needle tube 6, the limiting plate 31 and the interior of the outer cylinder 1 are interconnected, so as to facilitate ink absorption through the ink-absorbing needle tube 6.

[0029] By setting the retraction component 3, after ink absorption is completed, the lifting plate 34 can be manually pulled out to drive the two push-pull rods 33 to pull out the limiting plate 31, so that the limiting plate 31 is pulled out from the threaded base 5, and the two limiting blocks 32 slide up and down along the two sliding grooves 7 respectively, limiting the movement of the limiting plate 31. At the same time, the ink absorption needle tube 6 is retracted into the outer cylinder 1 for storage, thereby avoiding the ink absorption needle tube 6 being located outside the outer cylinder 1 after ink absorption is completed, which may easily injure the user. It is convenient to retract the ink absorption needle tube 6 in time for storage, improving the safety of this utility model.

[0030] like Figure 1-3 As shown in Figure 5, the top of the outer cylinder 1 is provided with an ink-absorbing assembly 4 for ink absorption. The ink-absorbing assembly 4 includes a piston plate 41, which is located on the top of the limiting plate 31. Slider blocks 42 are fixedly provided on both sides of the piston plate 41. The sliders 42 are slidably disposed inside the slide groove 7 to facilitate the lifting and lowering of the piston plate 41, thereby driving the two sliders 42 to lift and lower along the two slide grooves 7 respectively, thus limiting the movement of the piston plate 41. A pressing rod 43 is fixedly provided on the top of the piston plate 41. The top end of the pressing rod 43 penetrates the top of the outer cylinder 1. A handle 45 is fixedly provided on the top end of the pressing rod 43, and the handle 45 is located on the top of the slot 2, so as to facilitate pulling the handle 45 to drive the pressing rod 43 and the piston plate 41 to lift and lower inside the outer cylinder 1 to realize the ink absorption function.

[0031] A spring 44 is sleeved on the outside of the pressing rod 43. The top and bottom ends of the spring 44 are fixedly connected to the bottom of the handle 45 and the bottom of the slot 2, respectively, so that pulling the handle 45 can drive the pressing rod 43 to rise and fall, and at the same time drive the spring 44 to stretch or contract. The two push-pull rods 33 are respectively located on both sides of the pressing rod 43, and the two push-pull rods 33 pass through both sides of the piston plate 41, so that the push-pull rods 33 can pass through the piston plate 41 and move.

[0032] By setting up the ink absorption assembly 4, when ink absorption is needed, pushing the lifting plate 34 drives the two push-pull rods 33 to push the limiting plate 31 down, and at the same time, the two limiting blocks 32 descend along the two sliding grooves 7, pushing the limiting plate 31 to the bottom of the threaded base 5 and abutting against the lifting plate 34. Then, pulling the handle 45 drives the spring 44 to stretch or contract, causing the piston plate 41 at the bottom of the pressing rod 43 to rise and fall along the inside of the outer cylinder 1. At the same time, the two sliders 42 also slide and rise and fall along the two sliding grooves 7 respectively, so as to facilitate the drawing of ink into the inside of the outer cylinder 1 through the ink absorption needle tube 6, thereby achieving the purpose of ink absorption.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
