Description
Technical Field
The invention relates to cultural writing articles, in particular to a marking pen or a whiteboard pen for writing.
Background
In cultural writing articles, marker pens are widely used as marking tools on various material packaging boxes, glass, ceramic and metal products, wood and the like, and white board pens are widely used as teaching and office tools for writing on white boards. Ink pens are classified into water-based pens, oil-based pens, gel-ink pens and medium-oil pens.
The ink used in the water pen is pure water, and is generally used on a substrate with strong absorptivity, such as paper. It can be erased even if written on a non-absorbent substrate such as a whiteboard. The writing paper has no back mark, and has the advantages of good writing hand feeling and writing quality. The water pen comprises: pens, ordinary fountain pens, sign pens, highlighters, watercolor pens, white board pens, and the like.
The ink used by the oil pen is oil, is not easy to fade, is insoluble in water, and is not easy to render and dissolve when meeting water. The oil pen can write on the absorbing and non-absorbing substrate plane and is difficult to erase. The oily pen includes: ball point pens, marker pens, and the like.
The ink used by the gel pen has the property between that of a water-based pen and that of an oil-based pen, the storage time of writing marks is longer than that of the water-based pen and is close to that of the oil-based pen, the writing marks are not easily dissolved when meeting water, and the writing hand feeling and the writing quality are far better than those of the oil-based pen. Gel-ink pens, such as gel-ink ball-point pens, combine the advantages of fountain pens and ball-point pens and are often used when writing certain documents that need to be preserved.
The medium oil pen is a neutralized product of a neutral ball pen and an oil ball pen. The viscosity of the ink of the medium-density ball pen is low and is close to that of a neutral pen, so that the characteristics of smooth writing, quick drying after writing and easy cleaning of leakage liquid of the neutral pen are kept, and the defects of over-viscosity and insufficient smoothness of writing of the oil-density ball pen ink are avoided. The medium oil pen is also called medium oil ball pen.
In all the pens, the marker pen, the mark pen, the white board pen and the water color pen which have the characteristic of large pen point exposure area, particularly the marker pen, the mark pen and the mark pen with oily ink and low viscosity, have the characteristics of serious solvent volatilization and dry ink during the writing process, particularly when a pen cap is lost or is forgotten to cover the pen cap tightly, and greatly shorten the service life of the pen due to the strong volatility of the ink. Therefore, the marking pen with the telescopic pen head not only prolongs the service life of the pen, reduces waste and makes the best use of things, but also has the effect of protecting the environment, and has important practical significance to consumers and the whole society.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a marking pen with a telescopic pen head and long service life.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a long-service-life marking pen with a telescopic pen head mainly solves the problem that the service life is greatly shortened as the printing ink of the existing oil-based and water-based marking pens is easy to volatilize. The method is characterized in that:

An all-round ultra-thin end cap outer edge (115) which has the functions of concentrically positioning the relative position between the ultra-thin end cap (11) and the penholder tube (21) and preventing the ultra-thin end cap (11) from falling off is arranged at a proper position at the tail of the cap; an outer edge (315) of the thin-end pen cap in a full-circle shape, which has the functions of concentrically positioning the relative position between the thin-end pen cap (31) and the pen holder tube (21) and preventing the thin-end pen cap (31) from falling off, is arranged at a proper position at the tail of the pen cap.
The middle part of the tail end of the ultra-thin end pen cap (11) is provided with an ultra-thin end pen holder passing/blocking edge (213) which is used for passing when the ultra-thin end pen cap extension spring (112) is compressed and blocking the ultra-thin end pen cap pen holder edge passing/blocking edge (114) in the shape of a double-jazz filter which is retracted due to the rebound of the spring; a thin end cap barrel pass/block rib (314) in the shape of a double jasper filter which is retracted by spring rebound is blocked by passing the thin end barrel pass/block rib (214) when the thin end cap extension spring (312) is compressed by the thin end barrel pass/block rib (214) provided in the middle of the end of the thin end cap (31).
The penholder arrises on the filter-shaped pen cap with double notches can pass/block arrises, and the number of the penholder arrises can be designed to be 1 set or 2 sets.
Meanwhile, a very thin end pen holder passing/blocking edge (213) in a short arc shape for compressing the very thin end pen cap extension spring (112) to pass through the very thin end pen cap pen holder ridge passing/blocking edge (114) and blocking the very thin end pen cap extension spring (112) from rebounding backward and a very thin end pen holder passing/blocking edge (214) in a short arc shape for compressing the thin end pen cap extension spring (312) to pass through the thin end pen cap pen holder ridge passing/blocking edge (314) and blocking the thin end pen cap extension spring (312) from rebounding backward are respectively arranged at appropriate positions on both sides of the middle part of the pen holder tube (21).
An ultra-thin end cap extension spring (112) is arranged between an ultra-thin end cap extension spring blocking edge (113) and an ultra-thin end pen holder passing/blocking edge (213), an ultra-thin end cap extension spring (312) is arranged between a fine end cap extension spring blocking edge (313) and an ultra-thin end pen holder passing/blocking edge (214), and the extension spring is firmly contacted with the edges at two sides and is not separated from the edges at two sides through an adhesive or a specially designed bayonet.
In addition, the tip of the ultra-fine end pen cap (11) is provided with an ultra-fine end pen cap sealing rubber gasket blocking outer edge (116) and an ultra-fine end pen cap sealing rubber gasket blocking inner edge (117) which are all in a full-circle shape, and the middle of the ultra-fine end pen cap sealing rubber gasket (118) is provided with a compact and high-elasticity material; the tip of the thin-end pen cap (31) is provided with a full-circle-shaped thin-end pen cap sealing rubber gasket blocking outer edge (316), a thin-end pen cap sealing rubber gasket blocking inner edge (317), and the middle of the thin-end pen cap sealing rubber gasket is provided with a thin-end pen cap sealing rubber gasket (318) made of compact and high-elasticity materials.
Through holes with proper diameters are formed in the centers of the ultra-thin end pen cap sealing rubber gasket (118) and the thin end pen cap sealing rubber gasket (318), namely a pen core extending hole (119) of the ultra-thin end pen cap sealing rubber gasket and a pen core extending hole (319) of the thin end pen cap sealing rubber gasket; the diameter of the through hole is in the range of 0.1-10mm, so that the smooth passing of the ultra-thin end pen core (12) and the thin end pen core (32) is facilitated, and the through hole is kept in the best sealing state when no pen core passes through the through hole.
The material of the sealing rubber pad can be selected from compact, high-elasticity and high-contractibility rubber, silicon rubber, latex and the like. So as to ensure the smooth passing of the pencil lead (12) with the very thin end and the pencil lead (32) with the thin end, ensure the small hole at the center of the rubber mat to keep a closed state when no pencil lead passes by the aid of the high elasticity and the high contractibility of the rubber mat material, and prevent the volatilization of the printing ink solvent.
When the marking pen is used for writing, the pen holder tube (21) is rotated, so that the short circular arc-shaped edge of the ultra-thin end pen holder passing/blocking edge (213) or the fine end pen holder passing/blocking edge (214) on the pen holder is aligned with the opening of the double-jaspete filter edge of the ultra-thin end pen cap pen holder passing/blocking edge (114) or the fine end pen cap pen holder edge passing/blocking edge (314), after a compression spring passes through the opening, the hand is released after rotating for a certain angle, and due to the rebound force of the compression spring, the ultra-thin end pen holder passing/blocking edge (213) or the fine end pen holder passing/blocking edge (214) on the pen holder retreats and abuts against the ultra-thin end pen cap pen holder passing/blocking edge (114) or the fine end pen cap pen holder edge passing/blocking edge (314) on the pen cap; meanwhile, in the process of compressing the spring, the tip of the pen core stabs and presses the small hole of the sealing rubber pad to expand the small hole, and the pen core extends out correspondingly through the rubber pad;
after the marker pen is used, a pen holder pipe (21) is rotated, and a very thin end pen holder passing/blocking edge (213) or a thin end pen holder passing/blocking edge (214) on a pen holder reversely passes through a very thin end pen cap pen holder edge passing/blocking edge (114) or a thin end pen cap pen holder edge passing/blocking edge (314) on a pen cap and abuts against a very thin end pen cap outer edge (115) or a thin end pen cap outer edge (315); meanwhile, the tip of the pen cap moves backwards due to the rebound tension of the compression spring, so that the pen core is withdrawn from the small hole of the sealing rubber pad, and the small hole automatically shrinks and is sealed due to the high elasticity of the material of the sealing rubber pad.
When the marking pen is used, the pen core can be extended and retracted by simple operations of holding the pen cap, rotating the pen holder tube, advancing or retracting and then rotating; the high-elasticity sealing rubber pad at the tip of the pen cap is tightly closed after the pen point is contracted, so that the effects of reducing the useless volatilization of the ink solvent and prolonging the service life of the marking pen are achieved.

Detailed Description
The invention is further illustrated by the following figures, examples and comparative examples.
Example 1
Referring to fig. 1, 2 and 3, the overall structure of the embodiment of the invention is schematically illustrated when the extension spring is in different states. The invention relates to a marking pen with a telescopic pen head and a long service life, and mainly solves the problem that the service life of the existing oil-based marking pen and the existing water-based marking pen is greatly shortened due to easy volatilization of ink. The method is characterized in that: the inner wall of the tail end of the pen cap is sequentially provided with a spring blocking edge, a pen holder edge passing/blocking edge and an outer edge, the outer wall of the pen holder tube is provided with a passing/blocking edge, and a telescopic spring is connected between the spring blocking edge on the pen cap and the passing/blocking edge on the pen holder. The pen cap has sealing rubber pad in the tip to block the outer edge and the inner edge, sealing rubber pad of compact and high elasticity material in the middle, and through hole in the center of the sealing rubber pad in proper size to ensure the smooth passing of pen core and the sealed state of the small hole in the center of the rubber pad. When the pressure on the two sides of the sealing rubber gasket is constant, the stability of the saturated vapor pressure of the solvent in the pen cap can be ensured by the airtightness of the pen core extending hole, so that the unnecessary loss of the ink solvent due to volatilization is prevented, and the effect of long service life is achieved.
When the marking pen of the embodiment is used for writing, taking the ultra-thin end pen point as an example, as shown in fig. 2 and 7, the ultra-thin end pen cap (11) is held, the pen holder tube (21) is rotated, so that the short arc-shaped edge of the ultra-thin end pen holder passing/blocking edge (213) on the pen holder is aligned with the opening of the double-gap jade filter edge of the ultra-thin end pen cap pen holder passing/blocking edge (114) on the corresponding pen cap, after the compression spring passes through the opening, the hand is released after the compression spring is rotated for a certain angle, and due to the rebound force of the compression spring, the ultra-thin end pen holder passing/blocking edge (213) on the pen holder retreats and abuts against the ultra-thin end pen cap pen holder passing/blocking edge (114) on the pen; meanwhile, in the process of compressing the spring, the tip of the pen core stabs and presses the small hole of the sealing rubber pad to expand the small hole, and the pen core extends out correspondingly through the rubber pad.
After the marker is used, as shown in fig. 3 and 8, the pen cap with the very thin end (11) is held, the pen holder tube (21) is rotated, the pen holder passing/blocking edge (213) of the very thin end on the pen holder reversely passes through the pen holder passing/blocking edge (114) of the pen cap with the very thin end, and abuts against the outer edge (115) of the very thin end pen cap; meanwhile, the tip of the pen cap moves backwards due to the rebound tension of the compression spring, so that the pen core is withdrawn from the small hole of the sealing rubber pad, and the small hole automatically shrinks and is sealed due to the high elasticity of the material of the sealing rubber pad. After the hand is loosened, due to the contraction force of the expansion spring in the expansion state, the ultra-fine end cap expansion spring (112) retracts, so that the ultra-fine end penholder connected with the ultra-fine end cap expansion spring passes/blocks the outer edge (213) to move left, and further drives the penholder to move left, as shown in fig. 1 and 6, the expansion spring returns to the original relaxation state.
FIG. 5 is a schematic diagram showing the related structures and relationships between the cap and the shaft when the tip of the very thin end pen of the present embodiment is retracted and extended.
Fig. 2 is a schematic diagram of a full structure of the pen head in an extended state with the pen cap extension spring of the very thin end and the thin end compressed according to the embodiment of the present invention, and fig. 7 is a schematic diagram of an enlarged and left-view structure of the pen head, the pen holder, and the pen cap extension control portion when the pen head is extended with the pen cap extension spring of the very thin end compressed in this state.

Fig. 1 is a schematic view of the entire structure of the ultra-thin end and the thin end of the retractable spring of the cap of the pen in the retracted state, and fig. 6 is a schematic view of the enlarged and left structure of the pen point, the pen holder and the retractable control part of the cap of the pen in the retracted state.
Comparative example
Fig. 4 is a schematic diagram of the overall structure of a conventional marker in the market, such as a morning light MG-2130 or SPM21302 dual-head marker. It can be seen that the very thin end and the thin end of the pen holder tube (21) are respectively provided with a primary pen cap interference fit outer edge, the very thin end pen cap interference fit outer edge (211) and the thin end pen cap interference fit outer edge (212), and correspondingly, the inner walls of the very thin end pen cap (11) and the thin end pen cap (31) are respectively provided with a very thin end pen cap interference fit inner edge (111) and a thin end pen cap interference fit inner edge (311) for tight fit of the very thin end pen cap (11) and the thin end pen cap (31) with the pen holder tube (21). The design can ensure the close fit of the extremely-thin end pen cap (11) and the thin end pen cap (31) with the pen holder tube (21) for the first time, and when the extremely-thin end pen cap (11) is taken off and the extremely-thin end pen core (12) is used for writing, or the thin end pen cap (31) is taken off and the thin end pen core (32) is used for writing, the taken-off corresponding pen cap is difficult to be closely and firmly matched with the pen body, or the pen holder tube or another pen cap for the second time, so that the corresponding pen cap falls off or is lost in the using process. Once the cap is removed, difficult to find, or lost, the marker can be left open for extended periods of time, exposed to the atmosphere, causing the ink to quickly dry out and the marker to fail. Therefore, the precautionary measure or design can be conveniently extended out when in use and retracted when not in use, and the pen cap is permanently prevented from being lost when in use, so that the service life of the pen is prolonged, the waste is reduced, the best use of the things is realized, the environment is protected, and the practical significance is important for consumers and the whole society.
Example 2
Referring to fig. 9, 10 and 11, the overall structure of the embodiment of the invention is schematically illustrated when the extension spring is in different states. It can be seen that the pen holder arris passing/blocking arris of the super thin end and thin end cap in the shape of a double-piece jades filter which is arranged in the middle of the tail ends of the super thin end cap (11) and thin end cap (31) and used for compressing the super thin end cap expansion spring (112) and the thin end cap expansion spring (312) to pass and blocking the corresponding spring rebounding backward can be designed into 1 sleeve or 2 sleeves. As shown in fig. 11, after the marking pen is used, taking the very thin end pen point as an example, the very thin end pen cap (11) is held, the pen holder tube (21) is rotated, the very thin end pen holder passing/blocking rib (213) on the pen holder reversely passes through the very thin end pen cap pen holder rib passing/blocking rib (114) and the very thin end pen cap 2 nd pen holder rib passing/blocking rib (120) on the pen cap, and then the pen holder tube (21) is rotated, at this time, the very thin end pen holder passing/blocking rib (213) on the pen holder abuts against the very thin end pen cap 2 nd pen holder rib passing/blocking rib (120), and the pen core exits from the small hole of the sealing rubber gasket, and the small hole is automatically shrunk and sealed due to the high elasticity of the material of the sealing rubber gasket. Therefore, in the design of the embodiment, the marker pen can reach a stable state when the telescopic spring is in an expansion state; further, the pen cap (11) with the very thin end is held, the pen holder tube (21) is rotated reversely, the projection of the short arc-shaped very thin end pen holder passing/blocking rib (213) on the pen holder is aligned with the filter-shaped gap of the very thin end pen cap No. 2 pen holder rib passing/blocking rib (120), after the hand is loosened, as shown in fig. 9, the telescopic spring returns to the original loose state, and the marker pen can also reach the stable state.
The above description is only exemplary of the invention as applied to a marker and is not intended to limit the scope and application of the invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the invention should be included in the protection scope of the invention.
