As shown in fig. 1 and fig. 2, the retractable pen of the embodiment of the present invention includes a pen point 1, a pen tongue 2, a pen neck 3, a pen shaft 4, a pen cap 5, an ink reservoir 6 and a sealing liner 7; the pen cap 5 is slidably sleeved at the front end of the pen holder 4, and a pen point hole 8 for the pen point 1 to extend out is formed in the front end of the pen cap 5; the pen item 3 is arranged in the pen cap 5, and the rear end of the pen item 3 is detachably connected with the front end of the pen holder 4; the ink storage container 6 is arranged in the pen holder 4, and the front end of the ink storage container 6 is detachably connected with the rear end of the pen item 3; the pen tongue 2 is inserted into the pen item 3, and the front end of the pen tongue 2 extends out of the pen item 3 and is connected with the pen point 1; the pen item 3 is internally provided with an ink inlet channel 9 which can inject the ink in the ink storage container 6 into the pen tongue 2; the sealing bush 7 is fixedly arranged in the pen cap 5, the sealing bush 7 is sleeved on the periphery of the pen item 3, and a dynamic sealing structure 10 is arranged between the sealing bush 7 and the pen item 3; the front end of the sealing bush 7 is a closed end 11, and the closed end 11 is provided with a self-closing cut through which the pen point 1 can be repeatedly inserted; a lower limit structure 12 and an upper limit structure 13 are arranged between the pen cap 5 and the pen neck 3, and when the lower limit structure 12 limits and fixes the pen cap 5 and the pen neck 3, the pen point 1 retracts into the sealing bush 7; when the upper limit structure 13 limits and fixes the pen cap 5 and the pen item 3, the pen point 1 extends out of the pen cap 5 through the sealing bush 7.

According to the embodiment of the utility model, when in use, the pen cap 5 is pushed downwards, the upper limit structure 13 fixes the pen cap 5 and the pen item 3, and at the moment, the pen point 1 passes through the elastic sealing element and extends out of the pen point 1 hole to the outside of the pen cap 5, so that the writing action can be started, the structure is simple, and the assembly and the use are convenient; when the pen cap is idle, the pen cap 5 is pulled upwards, the lower limit structure 12 fixes the pen cap 5 and the pen item 3, the pen point 1 retracts into the sealing bush 7 at the moment, and the sealing bush 7 isolates the pen item 3 to form a sealing cavity inside and outside, so that the pen item 3 and the ink storage liner 6 keep pressure balance, the air drying of the pen point 1 can be prevented, and the smooth ink discharging in the next use can be ensured.

Illustratively, the material of the sealing bush 7 is preferably silicone.

Illustratively, as shown in fig. 1 and 2, since the internal pressure of the ink storage bladder 6 is increased in consideration of the ambient temperature rise, carrying shaking and the like, and thus ink leakage is caused, in order to solve this problem, the closed end 11 is provided with an inwardly recessed arc groove 14, and the self-closing notch is opened on the arc groove 14. Therefore, the arc groove 14 can provide certain tension, ensure the pressure balance inside and outside the pen cap 3, and effectively prevent the phenomenon of ink leakage and overflow caused by overhigh internal pressure in the ink storage liner 6.

Illustratively, as shown in fig. 1 and 2, in order to facilitate the assembly of the sealing bush 7, the pen cap 5 includes a cap head and a cap body, and the cap head is detachably connected with the cap body. In specific implementation, the cap head is in threaded connection with the cap body, an annular clamping opening 15 used for fixing the sealing bush 7 is formed after the cap head is connected with the cap body, and an annular boss 16 matched with the clamping opening is arranged on the periphery of the sealing bush 7. Furthermore, the periphery of the sealing bush 7 is provided with an annular convex rib 17 abutted to the inner wall of the pen cap 5, so that the friction force between the periphery of the sealing bush 7 and the inner wall of the pen cap 5 can be reduced, the sealing bush 7 can be smoothly inserted into the pen cap 5, the pre-insertion is convenient, and meanwhile, after the cap head is connected with the cap body, the annular clamping opening 15 can clamp the annular boss 16, so that the sealing bush 7 is fixed.

Exemplarily, as shown in fig. 1 and fig. 2, a protective cover 18 matching with the shape of the nib 1 is formed at the end of the cap, and the nib hole 8 is opened on the protective cover 18; the pen cap 5 is connected with a pen clip 19, and the pen clip 19 is positioned on one side of the back surface of the pen point 1. Therefore, the protective cover 18 can protect the pen point 1, and the pen clip 19 is arranged on the back side of the pen point 1, so that writing is affected when the pen is used mistakenly, and the pen holding gesture is corrected.

Illustratively, as shown in fig. 3 and 4, the lower limit structure 12 includes a first lower limit buckle 20 and a second lower limit buckle 21 that are fastened to each other, the first lower limit buckle 20 is fixed to the outer periphery of the pen cap 3, and the second lower limit buckle 21 is fixed to the inner wall of the pen cap 5; the upper limiting structure 13 comprises a first upper limiting buckle 22 and a second upper limiting buckle 23 which are buckled with each other, the first upper limiting buckle 22 is fixedly arranged on the periphery of the pen item 3, and the second upper limiting buckle 23 is fixedly arranged on the inner wall of the pen cap 5. When spacing buckle when lock joint each other, can produce "crack" sound, the user distinguishes with this whether the buckle is fixed in place, effectively prevents to write because of the not hard up influence of cap for a brush 5 and item for a brush 3, facilitates the use.

For example, as shown in fig. 1 and fig. 2, in order to facilitate ink filling of an ink filling bottle (e.g. chinese utility model patents: cn201510585566.X, cn201510587210.X, CN201510585795.1, etc.), a silicone plug 24 capable of puncturing and filling ink repeatedly is disposed at the rear end of the ink storage bladder 6; and a puncture hole 25 opposite to the silica gel plug 24 is formed at the rear end of the penholder 4.

Illustratively, as shown in fig. 1 and fig. 2, the tongue 2 is provided with a water diversion part 26 extending axially, and the water diversion part 26 is inserted into the ink inlet channel 9 and forms a water diversion flow channel 27 with the inner wall of the ink inlet channel 9. Due to the design, gas-liquid separation can be realized in the ink feeding process, so that ink can smoothly flow to the pen point 1 from the ink storage container 6, and the ink break phenomenon in writing is effectively prevented.

Illustratively, as shown in fig. 1 and fig. 2, two radially protruding and axially extending drainage ribs 28 are symmetrically disposed on the inner wall of the ink storage bladder 6, and a water guide groove 29 is formed between the two drainage ribs 28. By adopting the design, gas-liquid separation can be realized in the ink injection process, the ink layering and disconnection of the ink storage liner 6 can be effectively prevented, and the ink can be ensured to be smoothly filled in the ink storage liner 6.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
