Abstract

The utility model discloses a mark pen. A pen point is arranged in a front chamber welded up of a pen end and a pen holder. The inner end of the pen point is close up to a rolled wrapped core, of which the rear part is a closed liquid storage chamber. The utility model is characterized in that a water storage device is arranged between the rolled wrapped core and the inner cavity wall of the pen holder. A water diversion rod close up to the rolled wrapped core is arranged in the water storage device, and the tail end of the water diversion rod is provided with a ball valve. The ball valve is closed in writing, so that ink liquid pressure in the liquid storage chamber of the pen holder is not downward any longer. The ball valve can be automatically opened when the writing is stopped, and the ink liquid replenishes toward the water diversion rod. The utility model has the characteristics of large volume, straight liquid type, even and smooth written process, no water shutoff, no dropping point, little dryness, long service life, etc., and is suitable for making signs in various occasions.

Description

Marking pen

The utility model relates to the writing culture articles for use, especially writes the marking pen of usefulness.

In the writing culture articles for use, marking pen is widely used as sign flags such as various material packing cases, glassware, timber, as the patent No. 96210658.5 " marking pen ", it is a kind of marking pen that is used for label symbol on the bodies of rod such as mao bamboon, cement pole, the storage intracavity liquid of this marking pen is directly oozed out by nib, easily cause dropping point and easy dry problem, service life is short.

The purpose of this utility model is the dropping point not in that a kind of fluent writing is provided all, is difficult for the marking pen of drying and long service life.

The purpose of this utility model realizes by following scheme: by being provided with nib in nib, the front end chamber formed of penholder seam, the inner adjacent rolled core of nib, the rear portion is the reservoir compartment of sealing, its improvements are to be provided with accumulator between described rolled core and the penholder internal chamber wall, be provided with the diversion rod of adjacent rolled core in the accumulator, tail end is provided with ball valve.

Marking pen by the utility model design has accumulator and diversion rod, and make check valve with ball valve, ball valve is shut when writing, make the black hydraulic coupling of penholder reservoir compartment no longer downward, so have the big direct-liquid type of capacity, writing process evenly smooth, do not cut off the water supply, dropping point not, be difficult for characteristics such as drying, prolonged the service life of marking pen greatly, be applicable to the sign flag of various occasions.

Accompanying drawing 1 has provided structural representation of the present utility model.

Embodiment to the utility model is described in detail again below with reference to above-mentioned accompanying drawing.

As shown in Figure 1, marking pen is unified body by plastic nib (3) and penholder (8) through supersonic welding, its front end chamber is fibrous nib (1), the nib head is taper top rounding and exposes, be set with sponge volume (2) on built-in section, the interaction energy of sponge volume prevents that better pen from meeting the vanning carrying or throwing the black liquid that is caused the violent shake back in the process and fall the effect that.The cover tubular rolled core (4) of the inner adjacent cotton system of nib, and be concavo-convex edge combination on both faying faces, be provided with accumulator (6) between rolled core and the penholder internal chamber wall, accumulator is a plastics system, its outer circumference surface is provided with a plurality of compressions (11) that hold, and makes the inside and outside air pressure balance of pen.The penholder rear portion is the reservoir compartment (9) of sealing, and the black liquid in the reservoir compartment can replenish forward endlessly.

Be provided with the diversion rod (5) of adjacent rolled core in the accumulator, and both are concavo-convex cambered surface combination, the diversion rod is a fiber system, its effect is that liquid is attracted to come, and the tail end of accumulator is provided with ball valve (7), and ball valve is that steel ball is made check valve, pen is when writing, ball valve is closed valve port, stops fluid pressure downward, guarantees not dropping point of nib, after writing end, pen is in the flat state that crouches, and ball valve is opened automatically, and liquid can replenish to the diversion rod.

In order to prevent that the liquid in the reservoir compartment from flowing out, and is provided with " O " RunddichtringO (10) between penholder internal chamber wall and accumulator annular groove from the slit of penholder internal chamber wall and accumulator.Can also both solve with close-fitting, but the technology more complicated.

The utility model is disposable marking pen, also can be used for watercolor pencil, and can China ink liquid again is till using up.Nib, must the good black liquid of first can before the penholder seam and assemble inner body.
