Abstract

The utility model relates to a pump fountain pen which can suck ink without screwing off the pen tube. The rubber capsule on the tail part used for storing and sucking ink is removed on the basis of the nib, the pen head, the rubber capsule and the pen tube of an existing fountain pen. The tail end of the pen head is directly assembled with the pen tube and a simple pushing exhaust pump for storing and sucking ink. The exhaust pump is composed of a pressure lever, a plunger, a spring and a bottom plug which are arranged orderly from the top down inside a tubular pump casing. A lever body of the pressure lever projects up from the top end of inner part of the pump case. When the ink is sucked, the pressure lever is pressed down by hand in order to impel the plunger to exhaust the air inside the pen tube and suck ink, and enough ink can be suck by pressing the pressure lever repeatedly.

Description

Pump fountain pen

The utility model relates to a kind of pump formula water-color paintbrush.

At present, existing fountain pen pattern is a lot, structure generally all is made up of nib, nib, rubber capsule, a shell, this wherein also has a lot of improvement, but improved position all is the improvement on nib, nib, a shell, the ink distribution of tail, hold but still old pattern without exception of China ink part, that is, and a rubber capsule.As use the fountain pen ink distribution, and all to turn on the shaft of a writing brush, extruding capsule, and be difficult for making, beat sufficient ink, very inconvenient.

The purpose of this utility model provides a kind of pump formula water-color paintbrush, and it is at stylographic ink distribution, holds China ink improvement partly, can squeeze into ink in the pen easily under the situation of not turning on the shaft of a writing brush.

The purpose of this utility model can reach by following measure:

Known stylographic main body mainly is to be made of in a shell nib, nib, rubber capsule, its ink distribution, to hold China ink then be by being installed in the rubber capsule of afterbody, as the purpose that will realize that this is novel, just must remove the rubber capsule of existing water-color paintbrush afterbody, adopt a kind of new-type shaft of a writing brush and stylographic written winding, directly utilize the hollow ink of saving of the shaft of a writing brush, again at easy push-press type exhaust apparatus of shaft of a writing brush tail end winding, be named exhaust pump, be used for discharging the air in the pen, throw ink into.The exhaust pump structure is by depression bar, piston, spring, bottom plug is formed up and down in the tubulose pump case in proper order, wherein the shaft of depression bar protrudes upward from the top in the pump case, when ink distribution, the hand pressing lever presses down, promote piston, underpiston air flows into the shaft of a writing brush because of the discharge pump chamber that is squeezed, and the air that flows into shaft of a writing brush pressurized too, air is just discharged outside the pen by the blast pipe that is connected nib, like this, and when piston is depressed into certain limit, when coming on the springback, some air have just been lacked in the shaft of a writing brush, according to atmospheric pressure principle, at this moment, the outer atmospheric pressure of pen will be pressed into the shaft of a writing brush to ink along with the rebounding of piston outside pen.Pressing lever has just been realized the purpose that this is novel and so forth.

The utility model compared with prior art has following advantage: needn't turn on the shaft of a writing brush again, and the extruding capsule, only need push several down-pressed poles can play sufficient ink for it, and, the China ink amount of holding of the shaft of a writing brush is also Duoed two to three times than the China ink amount of holding of capsule at least, like this, can reduce the ink distribution number of times again.

The accompanying drawing drawing is described as follows:

Fig. 1 is the vertical section structural map of pump formula water-color paintbrush embodiment.

Fig. 2 is the plane of structure figure of parts among Fig. 1 (7).

The component names of number in the figure indication is (arranging in proper order by structure): 1, depression bar; 2, screw thread; 3, seal gasket; 4, piston; 5, pump case; 6, spring; 7, bottom plug; 8, pore; 9, translot; 10, slidable; 11, blast pipe; 12, hope sunglasses; 13, the shaft of a writing brush; 14, nib; 15, nib.

The utility model is described in further detail below in conjunction with accompanying drawing: the characteristics of each parts and purposes.Depression bar (1), the shaft of depression bar protrudes upward from the top in the pump case, and the length of shaft will match with the length of pump chamber, and its purposes is to be used for promoting piston; There are the screw threads of two to three buttons the lower end of shaft, and its purposes is, when ink distribution not, depression bar is fixed on the pump case; There is individual platen the lower end of screw thread, and it is to be used for holding seal gasket and the double piston of working as; The core of the bottom surface of platen has a small salient point, it be used for twisting prevent during depression bar platen and below piston bigger friction takes place.Screw thread (2), pump pen have the crucial screw thread in three places, i.e. shaft of a writing brush two ends and pump case top, and their pin thread and box will cooperate closely, can not breathe freely.Seal gasket (3), it is attached to above the platen of depression bar lower end, is used for preventing ventilative and ink exosmoses.Piston (4), piston is contained in below the depression bar, its size will with the pump case inwall cooperate close just, activity freely, its purposes is the air that is used for squeezing in the pump case.Pump case (5), pump case is a body, and there is screw thread at two ends up and down, and its length can be thrown ink into the air of its discharge and be advisable, and generally gets about 1/3rd of handwriting length overall and gets final product.Spring (6), spring is contained in below the piston, and its purposes is when piston is depressed, can have suitable elastic force that piston is pushed up back original position.Bottom plug (7), bottom plug is contained in below the spring, and its side also has screw thread, is used for bottom plug is fixed in the pump case, and the purposes of bottom plug is to hold spring.Pore (8), pore has two places, and one is on the bottom plug, four spileholes are arranged, and referring to Fig. 2, a center that is in slidable has one, the size of this pore will be equivalent to the sum total of four spilehole sizes above the bottom plug, and the purposes of pore is to be used for passing through air.Translot (9), referring to Fig. 2, it is used for the turn-knob bottom plug.Slidable (10) is a metal garden sheet, it be placed on bottom plug below, its diameter will be slightly smaller than the internal diameter of pump case, can slide up and down, its purposes is, when exhaust pump is in written lower end, slidable can drop on above the bottom plug automatically, covers four spileholes, stops ink to infiltrate pump chamber.Blast pipe (11), its height should reach below the slidable.Hope sunglasses (12), it is a transparent glasses lens that is embedded on the shaft of a writing brush wall, and it is used for looking around and has or not ink in the shaft of a writing brush.The shaft of a writing brush (13), the shaft of a writing brush are a hollow body, connect nib under it, on the air pump that runs in, be mainly used to accumulate ink.Nib (14) and nib (15), this novel improvement that does not relate to it, what adopt among the figure is known a large sum of stylus head, only slightly the joint of nib, the shaft of a writing brush is changed, but the existing various nib of this novel suitable installation.

Entire pump formula water-color paintbrush content as above is with the cap for brush again, be exactly a complete pump formula water-color paintbrush (annotate: be convenient the picture, the dimension scale of accompanying drawing is greater than real pen).
