Abstract

The utility model discloses a metal paint pen used for writing on the surface of metallic materials, mainly comprising a pen holder and a pen head. An assembly composed of a rotating back cover, a screw rod, a piston and a blade is arranged in the pen holder. The top part of the pen head is provided with a steel ball, and the steel ball is supported by a conical spring at the lower part of the pen head. The paint pen not only can be used for writing successfully on the surface of metal, but also can be carried conveniently.

Description

Metal paint pen

The utility model relates to a kind of painting pen of writing letter symbol or make a mark on metal material surface.

Nearly all being to paint to make marks at present in China's industrial production, generally is to dip in to paint to write or be coated with writing brush to paint, and not only efficient is low, wastes also more serious.In recent years a kind of painting pen that uses the nylon nib of China's import, because it adopts the principle of capillary percolation to make, writing on bright and clean surface does not have any problem, but writes on the surface of corrosion and greasy dirt, will make the nylon nib stop up, solidify, until scrapping.

The purpose of this utility model will provide a kind of exactly and can write smoothly on metal material and other materials surface, neither is subjected to too much restriction economical and practical again, and writing is clear eye-catching, is beneficial to the painting pen that keeps all the year round.

Above-mentioned purpose of the present utility model reaches like this: the assembly of being made up of rotation bonnet, screw rod, piston and blade is set in pen container; And establish a steel ball at the top of nib, support by a volute spring below the steel ball.

The utility model adopts the following drawings:

Fig. 1 is the overall structure profile of the utility model painting pen;

Fig. 2 is the written structural representation of the utility model painting pen;

Fig. 3 has the outside drawing of novel another embodiment for this reality.

Below in conjunction with drawings and Examples the utility model is carried out more detailed explanation.

As shown in Figures 1 and 2, painting pen is made up of the cap for brush 1, pen container 5, rotation bonnet 7, screw rod 9, piston 8, blade 10 and nib 4.When using this, rotation bonnet 7 will rotate by lead-screw 9, so differ two projections that two screw threads at 180 ° of angles just promote on the piston 8 on the screw rod 9 piston forward is moved, and the paint that is equipped with in the pen container 5 to the nib 4 the pushing, make it to flow out through spring 3 and steel ball 2, finish the effect of writing.Blade 10 plays stirring action along with rotation and pushing motion together, and is more fluent to prevent from inner paint precipitation, to cooperate spring 3 to make to write.

Nib 4 is made inserts by metal material or metal material and plastics, is the hollow taper shape, and its bottom employing thread connecting mode is connected with outlet 6 on the pen container 5.There is a steel ball 2 on top in nib 4, is provided with a volute spring 3 between steel ball 2 and outlet 6, lives steel ball 2 in order to elastic bearing.When not using, external force does not act on steel ball 2, because of the elastic force of spring 3 pushes up back original position to steel ball 2, plays sealing process, and paint can not flow out.During use, steel ball 2 is when being write body surface and contacted, external force retreats steel ball 2, paint can flow out from the space between nib and the steel ball 2 because of certain pressure is arranged in the pen, and the rolling of steel ball 2 and the user variation of exerting oneself when writing, what that paint flows out spring 3 just regulate at an easy rate.When nib when body surface leaves, spring 3 pushes up back original position to steel ball 2, is obturaged in written hole, and paint can not be flowed out at once.

In order to adapt to the needs of each side, the utility model has also designed a kind of painting pen (as Fig. 3) of soft pen container, and soft pen container 5 is made by the fine aluminum pipe, just like the dentifrice tube of domestic production at present.When extruded aluminum tube, the paint in the pen container 5 can enter nib 4 from exporting 6.

Adopt painting pen of the present utility model, can not only improve writing quality, also improved operating efficiency, can also write and make symbol in the metal surface of corrosion and greasy dirt in addition.
