Description

Marking pen with ink refilling function

Technical Field

The invention relates to the technical field of writing tools, in particular to a marking pen capable of refilling ink.

Background

The writing tool refers to a tool for writing, generally used for recording or writing characters, and is mainly a pen-like product. The pen products are classified into fountain pens, ball-point pens, pencils, propelling pencils, marking pens, solid-state pens and dip pens according to different writing modes.

The writing tools, which are used for writing on one or more materials such as paper, wood, metal, glass, plastic, enamel, ceramic, etc. as marks, are commonly called marking pens by making pen points with plastic, fiber, etc., filling oil or water writing medium, and matching with pen holders. Marking pens are further classified into oil-based marking pens, water-based marking pens, highlighters, white board pens, paint pens, and water-color pens according to writing media. Because the ink of the marking pen is easy to volatilize, the pen holder, the pen point and the rear seal are in interference fit to ensure sealing, so that the whole pen can be discarded after the ink with the core wrapped in the pen holder is used, and the material waste and the environmental pollution are caused. In order to solve the problem, the existing market has two modes for adding ink to the marker pen to realize recycling, wherein one mode is

The mode is that ink is added at the front end of the pen, namely the cotton core pen point on the pen point is taken out, then the ink is added through the pen point hole and is injected into the core-spun core, and the ink adding mode is adopted, so that hands and a desk are easily dirtied, and the operation is inconvenient; the other way is to add ink at the rear end of the pen, and forcibly take out the rear seal by using a tool, but the operation is labor-consuming, the pen holder is easy to damage, and the sealing performance of the product is influenced.

Disclosure of Invention

The invention mainly aims to provide a marking pen capable of refilling ink, and aims to solve the problems that in the prior art, the hand is easily dirtied by refilling ink, the labor is wasted, the operation is inconvenient, a pen holder is easily damaged, and the sealing is influenced.

To achieve the above object, the present invention provides a re-inked marker comprising: the top of the rear seal is provided with a sealing part and a first ink adding hole; the connecting piece, set up second inking hole and sealed muscle on the connecting piece, back seal through sealed muscle with the connecting piece tight fit, when not adding the china ink, sealing portion tight fit the second adds the china ink hole and seals, when adding the china ink, it makes to rotate to seal back first inking hole with second adds the china ink hole intercommunication.

Furthermore, the longitudinal section of the second ink adding hole is an inverted round table, the longitudinal section of the sealing part is an inverted round table, and the diameter of the sealing part is larger than that of the second ink adding hole. The longitudinal sections of the second ink adding hole and the sealing part are all inverted circular truncated cones, namely the longitudinal sections are matched with each other to form linear sealing between the inclined surfaces, and the sealing performance is good.

Further, the sealing portion includes a connecting surface and a sealing surface, the connecting surface is connected together along a perimeter of the sealing surface, the connecting surface is tightly fitted with the second ink adding hole, and the sealing surface seals the second ink adding hole.

Further, the sealing part and the first ink adding hole are positioned on the same straight line. The sealing part and the first ink adding hole are arranged on the same straight line, namely the back seal rotates 180 degrees, the operation is convenient, the rotation over position is avoided, and the deviation of the first ink adding hole and the second ink adding hole is avoided.

Furthermore, the connecting piece is provided with a bulge, the sealing part is provided with a groove, and the bulge is buckled with the groove. The bulge is buckled with the groove, so that the back seal is rotated to form a clamping point to indicate that the back seal is rotated to the position, namely the hand feeling of the back seal is increased to the position.

The marking pen further comprises a ring core, a pen holder, a pen point and a pen sleeve, wherein the ring core is located in the pen holder, the pen point penetrates through one end of the pen holder and is connected with the ring core, the connecting piece is tightly matched at the other end of the pen holder, the connecting piece is tightly matched and sealed by the rear seal, and the pen sleeve is sleeved at one end of the pen holder and is sealed.

Compared with the prior art, the invention has the advantages that:

1. labor saving: when adding the china ink, only need rotatory back to seal, make the sealing portion keep away from the second and add the china ink hole, make first hole and the second of adding china ink hole intercommunication and aim at, do not damage the pen-holder, the leakproofness is good.

2. Is convenient and fast: the rear seal does not need to be completely disassembled, the risk that ink on the rear seal stains other objects is eliminated, and meanwhile, hands do not contact the pen point during ink adding;

3. the rear seal adopts the sealing rib to be tightly matched with the connecting piece, so that the abrasion caused by friction is reduced by comparing with thread fit, the service life of the rear seal is prolonged, and the structure is simple.
