Technical Field
[0001] This utility model relates to the field of fountain pen technology, and in particular to a fountain pen ink-absorbing structure. Background Technology
[0002] A fountain pen is a writing instrument with a metal body. It holds ink through a hollow ink tube, and the ink is delivered through the feed and then through the nib.
[0003] Before using a fountain pen, the ink tube needs to be filled with ink. During the ink filling process, the pen grip inevitably comes into direct contact with the ink in the ink bottle, causing the pen grip to be contaminated with ink. After each ink filling, the pen grip needs to be wiped, and ink can easily get on your hands during wiping. It is evident that in the existing technology, the pen grip is easily contaminated during ink filling. Utility Model Content
[0004] To address the problem mentioned in the background art that ink absorption easily causes contamination of the pen grip, this utility model provides the following technical solution:
[0005] A fountain pen ink-drawing structure includes an ink tube installed inside the fountain pen body for drawing ink;
[0006] The pen body is equipped with a pen grip at its lower end, and the pen grip includes a first tube and a second tube.
[0007] The first tube body has a telescopic tube installed inside, and the telescopic tube has a pen tongue installed inside. The upper end of the first tube body has a pressure block for controlling the downward movement of the telescopic tube.
[0008] The lower end of the second tube is equipped with an adjusting tube for pushing the pressure block downward.
[0009] Furthermore, the outer wall of the first tube is fitted with a rubber sleeve, the inner wall of the first tube is fitted with a slider for limiting the telescopic tube, and the lower end of the outer wall of the second tube is machined with external threads.
[0010] Furthermore, a pen tip is installed on one side of the pen feed, a corrugated pipe is installed at the upper end of the telescopic tube, a magnetic ring is installed at the upper end of the telescopic tube, and a groove for sliding the slider is provided on the outer wall of the upper end of the telescopic tube.
[0011] Furthermore, a retaining ring for limiting the telescopic tube is installed on the inner wall of the first tube body, and a magnetic ring two for magnetic attraction with the magnetic ring one is installed in the middle of the retaining ring. Multiple push rods are installed on the upper end of the pressure block, and a spring for cooperating with the retaining ring to control the pressure block to reset is sleeved on the lower end of the pressure block.
[0012] Furthermore, the regulating pipe includes a third pipe body, a fourth pipe body is installed on the outer wall of the third pipe body, a fifth pipe body is installed on the outer wall of the fourth pipe body, and the inner wall of the third pipe body is machined with an internal thread that is threaded to the external thread.
[0013] Furthermore, a decorative ring is fitted onto the upper end of the first tube, and a decorative ring is fitted onto the lower end of the second tube.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] When the ink tube is drawing ink, rotating the fifth tube causes the fourth tube to rotate synchronously, which in turn drives the third tube to rotate. The interaction of the external and internal threads causes the adjusting tube to move downwards, and the third tube moves the push rod downwards. The push rod then moves the pressure block downwards, pushing the telescopic tube downwards. This causes the telescopic tube to move the pen tip downwards, and the lower end of the telescopic tube moves out of the lower end slot of the first tube. The protruding part of the telescopic tube is inserted into the ink, allowing ink to be drawn through the ink tube. After ink drawing is complete, rotating the fifth tube in the opposite direction causes the adjusting tube to move upwards and reset under the action of the external thread. Magnetic ring two magnetically attracts magnetic ring one, simultaneously driving the telescopic tube upwards. The ink on the surface of the telescopic tube is squeezed out by the first tube. Therefore, in this invention, the pen grip will not stick to ink during ink drawing. Attached Figure Description

Detailed Implementation
[0023] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0024] Please see Figures 1-4 This utility model provides a fountain pen ink-drawing structure, including an ink tube 10 installed inside the fountain pen body 100 for ink drawing. A pen grip 200 is installed at the lower end of the fountain pen body 100. The ink tube 10 provided by this utility model is prior art. The ink tube 10 can draw ink by squeezing or piston drawing. The pen grip 200 includes a first tube 210 and a second tube 220. The pen grip 200 of this utility model is formed by splicing the first tube 210 and the second tube 220, so that the user can use the fountain pen body 100 when holding the first tube 210.
[0025] The outer wall of the first tube 210 is fitted with a rubber sleeve 211. The rubber sleeve 211 increases the friction when holding the pen and improves the comfort of holding the pen. The rubber sleeve 211 is made of rubber or silicone and the surface can be designed with concave and convex textures so that the friction coefficient is high when the rubber sleeve 211 comes into contact with the finger, thereby increasing the friction when holding the pen, preventing the finger from slipping and ensuring writing stability.
[0026] The first tube 210 has a telescopic tube 240 installed inside, and a pen tongue 230 is installed inside the telescopic tube 240. The pen tongue 230 is fixed inside the telescopic tube 240, so that when the telescopic tube 240 moves up and down, it drives the pen tongue 230 to move up and down simultaneously, so as to facilitate the ink absorption operation.
[0027] The pen tip 231 is installed on one side of the pen feed 230. Since the telescopic tube 240 is sleeved on the outside of the pen feed 230, when drawing ink, the ink submerges the bottom of the telescopic tube 240, and the ink can be drawn in under the action of pressure difference.
[0028] Multiple sliders 212 for limiting the telescopic tube 240 are fixedly installed on the upper end of the inner wall of the first tube body 210. A corrugated tube 241 is installed in the middle of the upper end of the telescopic tube 240, and the upper end of the corrugated tube 241 is connected to the bottom of the ink tube 10. The lower end of the corrugated tube 241 is sleeved on the upper end of the pen tongue 230 so that ink can enter the interior of the ink tube 10 through the pen tongue 230 and the corrugated tube 241. The corrugated tube 241 prevents the ink tube 10 from being pulled when the telescopic tube 240 moves up and down. A magnetic ring 242 is installed on the upper end of the telescopic tube 240, and a groove 243 is opened on the outer wall of the upper end of the telescopic tube 240 for the sliders 212 to slide. The sliders 212 slide in the groove 243 to facilitate the positioning of the telescopic tube 240.
[0029] A retaining ring 250 for limiting the telescopic tube 240 is fixedly installed on the inner wall of the first tube body 210. A magnetic ring 251 for magnetic attraction with magnetic ring 242 is installed in the middle of the retaining ring 250. When the telescopic tube 240 is inserted into the first tube body 210, the telescopic tube 240 moves closer to the retaining ring 250. Under the mutual magnetic attraction of magnetic ring 242 and magnetic ring 251, the telescopic tube 240 moves upward and abuts against the lower end of the retaining ring 250.
[0030] The upper end of the first tube 210 is equipped with a pressure block 260 for controlling the downward movement of the telescopic tube 240. The pressure block 260 includes a large ring and a small ring. Multiple push rods 261 are fixedly installed on the upper end of the pressure block 260, and the push rods 261 are fixedly installed on the large ring. The lower end of the pressure block 260 is fitted with a spring 270 for cooperating with the retaining ring 250 to control the pressure block 260 to reset. The spring 270 is fitted on the small ring of the pressure block 260. The upper end of the spring 270 abuts against the bottom wall of the large ring of the pressure block 260, and the lower end of the spring 270 abuts against the upper end of the retaining ring 250, so that the spring 270 always moves the pressure block 260 upward, so that the magnetic ring 251 magnetically attracts the magnetic ring 242, so that the lower end of the telescopic tube 240 is flush with the lower end of the first tube 210.
[0031] The lower end of the second tube 220 is equipped with an adjusting tube 280 for pushing the pressure block 260 downward. The adjusting tube 280 includes a third tube 281. A fourth tube 282 is fixedly installed on the outer wall of the third tube 281. A fifth tube 283 is fixedly installed on the outer wall of the fourth tube 282. The inner wall of the third tube 281 is machined with an internal thread 284 that is threadedly connected to the external thread 221. The lower end of the outer wall of the second tube 220 is machined with an external thread 221.
[0032] When the ink tube 10 draws ink, rotating the fifth tube 283 causes the fourth tube 282 to simultaneously rotate the third tube 281. With the cooperation of the external thread 221 and the internal thread 284, the adjusting tube 280 moves downwards, and the third tube 281 moves downwards relative to the push rod 261. The push rod 261 simultaneously moves the pressure block 260 downwards, causing the pressure block 260 to push the telescopic tube 240 downwards. This causes the telescopic tube 240 to move the pen tip 230 downwards, and the lower end of the telescopic tube 240 moves out of the first tube. The lower end of the body 210 has a groove, and the protruding part of the telescopic tube 240 is inserted into the ink. The ink tube 10 can then be used to draw ink. After the ink is drawn, the fifth tube 283 is rotated in the opposite direction. Under the action of the external thread 221, the adjusting tube 280 moves upward and resets. The second magnetic ring 251 magnetically attracts the first magnetic ring 242, which simultaneously drives the telescopic tube 240 to move upward. The ink on the surface of the telescopic tube 240 is squeezed out by the first tube 210. Therefore, when the ink is drawn, the pen grip will not stick to the ink.
[0033] A decorative ring 20 is fitted at the upper end of the first tube 210, and a decorative ring 30 is fitted at the lower end of the second tube 220. Both the decorative ring 20 and the decorative ring 30 are located between the third tube 281 and the fifth tube 283. The arrangement of the decorative ring 20 and the decorative ring 30 ensures that there are no gaps when the adjusting tube 280 moves up and down, thus increasing the aesthetics of this utility model.
[0034] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
