Oil leakage prevention gel ink pen

Technical Field

The utility model relates to a gel ink pen, especially a leak protection oil gel ink pen.

Background

The gel pen is the most important writing tool in work and study of people due to smooth and uniform writing hand feeling and long-term continuous writing capability, and plays an important role in daily office work and study. Gel-ink pens are generally composed of a pen core, a pen head, a pen container and a pen cap, wherein ink for writing the gel-ink pen is stored in the pen core, and a pen ball for writing is arranged in the pen head. When writing, the ink is injected into the pen head and is carried out by the pen ball to be printed on the paper. In the use process of the currently used gel ink pen, the condition that the oil output of the pen core is not well controlled can be found, and sometimes, too much oil is output, and the pen point leaks oil, so that the writing is fuzzy; sometimes, the pen point lacks oil due to too little oil, so that clear characters cannot be written, and the pen core needs to be thrown; when the pen is used for writing for a long time or the pen falls from a high position, the pen beads are easy to fall off from the pen head, and therefore a large amount of oil leakage can happen at the pen head.

Therefore, the existing gel-ink pen has the problems that the oil output of the pen core is not well controlled, and a large amount of oil leaks due to falling of the pen balls.

SUMMERY OF THE UTILITY MODEL

The embodiment is as follows:

as shown in figure 1, the oil leakage prevention gel-ink pen comprises a pen container 1 and a pen point 2, wherein a pen core 3 is arranged in the pen container 1, ink is filled in the pen core 3, and an opening is formed in the lower end of the pen core 3; the pen head 2 is connected with a pen holder 4 in a sliding manner, and a pen ball 41 rotationally connected with the pen holder 4 and an oil brush 42 wrapped outside the pen ball 41 are arranged in the pen holder 4; the upper end of the pen holder 4 is connected with a leakage-proof head 6 through a plunger body 5, the leakage-proof head 6 is in sliding connection with the pen container 1 through a compression spring 11, and the leakage-proof head 6 extends into the pen core 3 from an opening of the pen core 3 and is used for sealing or opening the pen core 3. The bottom of the leakage-proof head 6 is provided with an oil outlet 61 communicated with the oil brush 42.

The anti-leakage pen is characterized in that an annular boss 31 is arranged at an opening of the pen core 3, the anti-leakage head 6 comprises a sealing part 62 extending into the pen core 3 and an oil receiving part 63 located outside the pen core 3, the cross section of the sealing part 62 is T-shaped and extends into the upper part of the boss 31, an annular groove 64 is formed in the oil receiving part 63, the boss 31 is located in the annular groove 64, a gap is reserved between the boss 31 and the annular groove 64, and the oil outlet 61 is located at the bottom of the annular groove 64.

The oil outlet holes 61 are provided with a plurality of oil outlet holes, each oil outlet hole 61 is of an inclined outward structure, and the oil outlet holes 61 are communicated with the oil brushes 42 through flexible pipes 43 or oil passages.

The plunger body 5 comprises a first pressing plate 51 connected with the pen holder 4 and a second pressing plate 52 connected with the anti-leakage head 6, a connecting column 53 is arranged between the first pressing plate 51 and the second pressing plate 52, and the top surface of the second pressing plate 52 is provided with a first oil absorption cotton 54.

A plurality of limiting bulges 44 are further arranged above the pen ball 41 in the pen holder 4, gaps are formed between every two adjacent limiting bulges 44, and second oil absorption cotton 45 for plugging the gaps is arranged above the limiting bulges 44.

The working principle is as follows: when the pressure is applied to the ball-point pen 41 during writing, the pen holder 4 is pushed upwards under the counterforce, the leakage-proof head 6 is moved upwards through the plunger body 5, so that an outflow gap is formed between the leakage-proof head 6 and the opening of the pen core 3, ink flows into the annular groove 64 from the outflow gap, flows into the oil brush 42 through the oil outlet 61 and the flexible pipe 43 more uniformly, then the ball-point pen 41 is brushed by the oil brush 42, the ink is uniformly smeared on the ball-point pen 41, and writing is smooth; the leakage-proof head 6 receives the oil flowing out from the outflow gap through the annular groove 64, so that the oil output can be effectively controlled, the amount of the ink flowing out each time is limited, and the phenomenon that the writing is influenced due to too much or too little ink seepage is avoided; when no pressure is applied for writing, the leak-proof head 6 seals the opening of the cartridge 3 under the downward action of the compression spring 11 to avoid ink seepage; even if the ball 41 falls off, the leakage preventing head 6 is not affected and a large amount of ink does not bleed out.

The plunger body 5 enables the anti-leakage head 6 to be stably pushed through the structure of the first pressing plate 51, the connecting column 53 and the second pressing plate 52, and the first oil absorption cotton 54 is arranged to absorb redundant ink flowing out of the anti-leakage head 6; the limiting protrusion 44 is used for limiting the installation position of the pen ball 41, so that the writing stability of the pen ball 41 is improved, and if the ink attached to the pen ball 41 is too much, the second oil absorption cotton 45 can absorb the redundant ink at the pen ball 41, so that the writing oil quantity of the pen ball 41 is effectively controlled, and the oil leakage condition is further avoided.

The details of the present invention are not described in the prior art, and therefore, are not specifically described herein.
