Pen holder assembly with ink locking function

Abstract

The penholder assembly with the ink locking function comprises a penholder, a pen point, a cotton core assembly and a valve seat, the pen point, the cotton core assembly and the valve seat are installed in the penholder, the valve seat is provided with an ink inlet groove used for being connected with an ink bag, and the cotton core assembly comprises water diversion cotton and water blocking cotton which are arranged on the inner side and the outer side of the valve seat in a sleeved mode respectively. The water-blocking cotton is sleeved on the outer side of the valve seat, and compared with the water-guiding cotton, the water-blocking cotton is different in that the water-blocking cotton cannot actively absorb ink, normal ink supply of the water-guiding cotton is not affected, and the water-blocking cotton is not prone to falling off, so that the water-blocking cotton is not prone to falling off, and the water-blocking cotton is not prone to falling off. When the ink amount at the pen point is too large, the ink overflowing from the side face of the pen point enters the water locking cavity until the whole water blocking cotton is filled with the ink, and the ink leakage condition is avoided; when ink is not supplied to the ink inlet groove in time, the ink in the ink locking cavity flows to the pen point, and therefore the functions of ink locking, ink retaining and ink adding are achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of writing or drawing utensils, and in particular to a penholder assembly with an ink locking function. Background Art

[0002] A traditional direct liquid valve pen includes a pen barrel, and a nib, a cotton core, and a valve seat distributed inside the pen barrel from front to back. The valve seat is connected to an ink sac, so that the ink in the ink sac is guided to the nib through the cotton core to facilitate normal writing. However, when the pen barrel is swung or in a low-pressure environment such as at high altitude or on a plateau, the ink sac is prone to leaking ink, causing the ink to overflow, affecting the normal carrying or writing of the direct liquid pen. Summary of the Invention

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a pen body assembly with an ink locking function, including a pen body, and a pen tip, a cotton core assembly and a valve seat installed in the pen body, the valve seat is provided with an ink inlet groove for connecting the ink bag, the cotton core assembly includes water-drawing cotton and water-blocking cotton respectively sleeved on the inner and outer sides of the valve seat, the two ends of the water-drawing cotton are respectively connected to the pen tip and the ink inlet groove, the water-blocking cotton sleeve is provided with a pen tip, and the water-blocking cotton is provided with a water-locking cavity for locking water.

[0004] Using the above technical solution, the tail of the pen shaft is connected to the ink bag through the valve seat, and the ink in the ink bag flows to the pen tip through the ink inlet groove and water-guiding cotton, thereby meeting the writing requirements; the difference between water-blocking cotton and water-guiding cotton is that water-blocking cotton will not actively absorb ink and will not affect the normal ink supply of water-guiding cotton. When the amount of ink at the pen tip is too much, the ink overflowing from the side of the pen tip enters the water locking cavity until it fills the entire water-blocking cotton, avoiding ink leakage; when the ink inlet groove is not supplied with ink in time, the ink in the water locking cavity flows to the pen tip, thereby realizing the functions of locking, retaining and replenishing ink.

[0005] The utility model is further configured such that the water-blocking cotton is formed by interweaving a plurality of plastic fibers, and the gaps between the plastic fibers form a plurality of water-locking cavities.

[0006] Using the above technical solution, the water-blocking cotton is a hollow cylinder formed by interweaving multiple PET fibers, and the PET fibers are interwoven to form several water-locking cavities of different sizes that are interconnected, so that the overflowed ink fills the water-blocking cotton along each water-locking cavity.

[0007] The utility model is further configured such that the water-blocking cotton is provided with a hollow groove, and the pen tip, the water-guiding cotton and the valve seat are coaxially distributed in the hollow groove.

[0008] Furthermore, the valve seat is provided with a rear rod for opening the ink bag, and an upper ring portion for clamping the water-blocking cotton. The water-guiding cotton is sleeved on the inner side of the upper ring portion. Reinforcing ribs distributed in a circular pattern are provided between the rear rod and the upper ring portion. The rear rod and the upper ring portion are combined to form the ink inlet groove, and the water-guiding cotton is arranged at the ink inlet groove.

[0009] Using the above technical solution, the water-drawing cotton is installed on the inner side of the upper ring, and its end face abuts against the rear rod and the reinforcing rib at the same time, increasing the contact area of ​​the valve seat supporting the water-drawing cotton. The two ends of the water-drawing cotton only face the ink inlet groove and the pen tip, avoiding the water-blocking cotton affecting the normal ink supply of the water-drawing cotton, making writing smooth.

[0010] The utility model is further configured such that the valve seat is provided with an outer ring portion, the water-blocking cotton is sleeved between the outer ring portion and the upper ring portion, the valve seat is sleeved in the pen body through the outer ring portion, and the pen body is provided with a step portion and a raised portion on both sides of the outer ring portion respectively.

[0011] By adopting the above technical solution, the outer diameter of the water-blocking cotton is smaller than the inner diameter of the outer ring, so that the water-blocking cotton does not contact the pen shaft, preventing the ink in the water-blocking cotton from flowing out along the inner wall of the pen shaft, and maintaining the water-locking effect of the water-blocking cotton.

[0012] The utility model is further configured such that a tapered portion is provided at one end of the pen tip facing the water-drawing cotton.

[0013] By adopting the above technical solution, the end face of the water-drawing cotton is squeezed and deformed by the tapered portion, thereby increasing the contact area between the water-drawing cotton and the pen tip, and making the ink flow smoothly.

[0014] The present invention is further configured such that the pen holder is a transparent pen holder.

[0015] By adopting the above technical solution, the structural state of the water-blocking cotton can be intuitively observed through the transparent pen barrel, which can prevent the water-blocking cotton from being dislocated and deformed during the installation process and losing its function of locking and retaining ink. The ink supply state can be observed by observing the change in the amount of ink on the water-blocking cotton to determine whether the ink is cut off.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Water-blocking cotton is sleeved on the outer side of the valve seat. The difference between water-blocking cotton and water-drawing cotton is that water-blocking cotton will not actively absorb ink and will not affect the normal ink supply of water-drawing cotton. When there is too much ink at the nib, the ink overflowing from the side of the nib enters the water-locking cavity until it fills the entire water-blocking cotton, thus avoiding ink leakage; when the ink inlet groove is not supplied with ink in time, the ink in the water-locking cavity will flow to the nib, thereby realizing the functions of locking, retaining and replenishing ink.
