Description

Inflated pressure oil outlet device for ball pen

The present invention relates to a kind of pressurizer of inflating.

The always easy oil-break of ball pen.When writing with ball pen, usually pen core is just not fuel-displaced while writing.Even new pen core also has this phenomenon.When pen core was not fuel-displaced, people always drew pen core on paper or paper shell with strength, but how the metal marker core is not fuel-displaced yet sometimes, can mark oil sometimes, but pen core is not fuel-displaced again a moment later.

The present invention's " inflated pressure oil outlet device for ball pen " is by inflating in pen core, make gas pressure intensity increase in the pen core, when air pressure is increased to when enough, oil column will move forward under gas pressure in the pen core, like this, the oil column that disconnects is communicated with, and pen core top and tip do not have the oil place and be full of this mode of oil and make pen core fuel-displaced.

The present invention's " inflated pressure oil outlet device for ball pen " is made up of a thinner air hose, top, spring, push rod, thicker air hose and piston.

The present invention's's " inflated pressure oil outlet device for ball pen " main part is a piston.Piston can be divided into two parts: the part that piston ring is remaining with removing piston ring.

There are two breach in the edge of the end face that removes the remaining part of piston ring of piston, and two breach are on same annulus, and relatively.The bottom surface is identical with the end face radius, but the bottom surface non-notch.Between end face and the bottom surface cylinder, the i.e. neck of piston.The cylindrical bottom surface of neck radius is less than the bottom surface radius of piston, but greater than place, the inboard arc limit radius of a circle of piston-top surface breach.There are two notches cylindrical side.The bottom surface of two notches is on the side of cylinder of upper bottom surface at place, the inboard arc limit circle with two breach of piston-top surface, and a limit of the bottom surface of two notches overlaps with the inboard arc limit of two breach of piston-top surface, another limit on the other side is on the piston bottom surface, specifically, on the intersection of notch bottom surface place cylindrical side and piston bottom surface.Other two limits of notch bottom surface are vertical with the piston bottom surface, and its length equates with cylinder height.Notch communicates with breach on the piston-top surface.The bottom surface of piston has also served as the sidewall of described notch.The end face of piston, bottom surface and middle cylinder three are connected as a single entity.

Piston ring set is at the neck of piston, promptly is enclosed between the end face of piston and the bottom surface on the cylinder.

The bottom of piston is fixed on the piston rod.Piston rod is made of four fins.Every two adjacent fins at an angle of 90.These four fins are identical.The middle and upper part branch of each fin is a rectangle, and the lower part is that upper base is greater than the right-angled trapezium of going to the bottom.The end of piston rod is being fixed a disk, the handle of using when disk is the push-and-pull piston.

The interior diameter of the air hose at piston place (being the air hose that there is piston its inside) equates with the piston ring overall diameter, can make piston be close to the inwall of air hose just.This air hose has upper bottom surface, and there is round mouth the center of upper bottom surface.Also fixing a thinner air hose (its interior diameter is greater than the diameter of the circular hole of the upper bottom surface of the thick air hose of its below, the central lines of these two pipes) on the upper bottom surface of this air hose.The topmost of thin air hose is a valve, and valve is slightly tapered, can insert in the ball pen, and can be seated, and can not leak gas.

There is spring the inside of thin air hose, and the two ends of spring are headed on by top and push rod.There is through hole the center of top, and top is an annular, and the tip edge of through hole has several spokes being connected with the top top.Between every adjacent two spokes is a blow vent, and the top of top is fixed on the tube wall of thin air hose.

There is the muscle of several endways projections the side of the base of push rod, contacts with the air hose inwall, plays the role of positioning, and makes push rod upper and lower when mobile, can not depart from the center.The bottom of push rod has one to be the center of circle with the center of circle, bottom, and radius is slightly less than the annular lip of bottom radius of circle.Have one to be the circular notch in the center of circle with the center of circle, bottom in flange inside.The center of the bottom of notch also has a darker circular notch.Can alleviate the weight of push rod like this, air-flow is easy to push rod jack-up.

Be the disk that the center has through hole below the push rod, disk is fixed on the thin air hose tube wall, and air-tightness be arranged.And it is vertical with thin air hose.The annular lip of push rod bottom can tightly contact with the disk that has through hole.

The present invention's's " inflated pressure oil outlet device for ball pen " operation principle is as follows:

During use, the valve with the present invention's product is inserted in the pen core earlier, and is seated.

When being pulled outwardly piston, piston ring is subjected to frictional resistance effect upwards, leaves a gap with the piston bottom surface; Move down (outwards moving) along with piston, (space the disk that has through hole in from top land to thin air hose is first air cavity to first air cavity, down together) interior gas volume increases, pressure reduces (less than 1 atmospheric pressure), and at this moment ambient atmos enters in first air cavity by the gap between piston ring and piston bottom surface (above-mentioned gap) and the notch of piston neck (cylinder between piston-top surface and bottom surface) and the breach on the piston-top surface edge under the draught head effect.Piston is pulled to the bottom of pipe or when terminal, pushes inward piston again, and at this moment piston ring is subjected to the outside frictional resistance effect of tube wall, and piston ring tightly is attached on the piston bottom surface, makes that gas can not pass through blow-by of piston in first air cavity.Along with the reach of piston, gas volume reduces in first air cavity, and pressure increases, and (carefully the space from the disk that has through hole to the valve top is second air cavity in the air hose when first air cavity and second air cavity.When down together) interior gas pressure difference was greater than spring force, push rod was by gas jack-up in first air cavity, and gas enters second air cavity immediately in first air cavity.Gas density increases in second air cavity, and pressure increases, and gas (gas in second air cavity) enters in the pen core under draught head (second air cavity in gas and the pen core draught head of gas) acts on.When piston is pulled to the top of pipe, be pulled outwardly piston again, along with move down (outwards the moving) of piston, gas volume increases in first air cavity, and pressure reduces.When the pressure differential of gas in the gas in first air cavity and second air cavity during less than spring force, push rod resets under the spring force effect, tightly be pressed on the disk that has through hole, covered through hole above, make that gas can not enter first air cavity in second air cavity.In addition, when being pulled outwardly piston, piston ring is subjected to inwards the frictional resistance effect of (making progress), leaves a gap with the piston bottom surface.When the pressure of gas in first air cavity during less than 1 atmospheric pressure, ambient atmos by this gap and the notch of piston neck (position of the cover piston ring of piston) and the breach of top land, enters first air cavity under the draught head effect.When piston is pulled to the end (or bottom) of pipe, push inward piston again, piston ring is subjected to the outwards frictional resistance effect of (downwards), tightly is attached on the bottom surface of piston, makes the interior gas of first air cavity can not pass through blow-by of piston.Along with the reach of piston (on move), gas volume reduces in first air cavity, pressure increases, when the gas pressure difference in first air cavity and second air cavity during greater than spring force, push rod is by gas jack-up in first air cavity, and gas enters in second air cavity immediately in first air cavity, and gas density increases in second air cavity, and constancy of volume, so pressure increases.Gas enters in the pen core under draught head (second air cavity in gas and the pen core draught head of gas) acts on again in second air cavity.Reciprocating sliding piston like this, the oil column that the pen core internal gas pressure is increased to be enough to can promote in the pen core moves forward.When the oil column in the pen core moved forward under gas pressure, the oil column of disconnection was communicated with, and pen core top and tip do not have the oil place and be full of oil.Like this, pen core is just fuel-displaced.

Further specify below in conjunction with drawings and Examples.

Can see that by Fig. 1 the present invention has two air hoses: a thinner air hose 1 and a thicker air hose 2.The topmost of thinner air hose 1 is a valve 3.The head of top 4 is fixed on the tube wall.Spring 5 is headed on by top 4 and push rod 6.The disk 7 that has a through hole 8 is close to push rod 6 and is fixed on the tube wall.Plane, place, the following end distance of the hole wall of through hole 8 thin air hose 1 lower end is distance a little.The lower end of thin air hose 1 is fixed on the top of thick air hose 2.

Two air hoses can be with metal material system, also can be with plastics or resin system.

Be that example illustrates the present invention's's " ball pen inflate pressurizer " thin air hose 1 and several preferred forms of internal structure thereof with plastic products of the present invention or resin goods below:

First kind of embodiment: earlier with thin air hose 1 (comprising valve 3 and tapering part) injection moulding.The side that will come directly towards 4 head then is fixed on the inwall of pipe 1.Again spring 5 and push rod 6 are put into pipe, spring 5 is headed on by top 4 and push rod 6.The disk 7 that will have through hole 8 then is close on the inwall that push rod 6 is fixed on thin air hose 1.

Second kind of embodiment: thin air hose 1 and internal structure thereof also can be divided into three part systems: first is the part above top 4 of pipe, promptly manages 1 valve 3 and tapering part.This part directly injection moulding.Be the remainder separated into two parts of removing first of interface with pipe to manage 1 place, spring 5 center cross section again: top is divided into the second portion of pipe 1, and the bottom is divided into the third part of pipe 1.Pipe 1 second portion and inner top 4 thereof can be used as an integral injection molding (or with other known method making moulding); The third part and the inner disk that has through hole 87 thereof that also the head of top can be fixed on (head of top 4 is vertical with pipe 1) pipe 1 on the tube wall of this section pipe can be used as an integral injection molding, or with other known method making moulding.Also the disk 7 that has through hole 8 can be fixed on the tube wall.

Also can when giving second section pipe injection moulding, on inside pipe wall top end 4 positions, leave inward flange.To come directly towards 4 then and below this section pipe, put into pipe, and its top will be fixed on the inward flange of tube wall.When giving the 3rd section pipe injection moulding, on inside pipe wall, have and leave inward flange below disk 7 positions of through hole 8, the disk 7 that will have through hole 8 is then put into pipe above this section pipe, be fixed on the inward flange of tube wall, specifically, the edge at the back side that will have a disk 7 of through hole 8 is fixed on the inward flange of inside pipe wall.

At last, the first and the second portion of pipe coupled together, again spring 5 and push rod 6 are put into pipe, then the third part of above-mentioned connection tube and tube is got up in succession.

The third embodiment: in the time of in this way, at first the top radius of top 4 will be increased slightly, make it to equal the radius and the thickness sum of managing 1 tube wall of above-mentioned top 4; The radius that has the disk 7 of through hole 8 also will increase slightly, makes it to equal the above-mentioned radius and the thickness sum of managing 1 tube wall that has the disk 7 of through hole 8.With come directly towards 4 and the disk 7 that has a through hole 8 be that interface is divided into three sections with thin air hose 1: the part coming directly towards above in the of 4 of pipe 1 is first section.Pipe 1 be second section in top 4 and a section of having between the disk 7 of through hole 8.Below the disk 7 that has through hole 8 one section of pipe 1 is the 3rd section.With these three sections pipe injection mouldings respectively, the lower end with first section pipe is fixed on the top of top 4 then earlier.Again an end of second section pipe is fixed on the edge at the back side at top (head) of top 4.Then spring 4 and push rod 6 are put into above-mentioned tube connector, the edge that will have the disk 7 of through hole 8 again is fixed on the tube wall of lower end of tube connector, at last an end of the 3rd section pipe is fixed on the edge at the back side of the disk 7 that has through hole 8.

Thick air hose 2 has upper bottom surface, i.e. end face.There is round mouth 9 center of end face.The radius of round mouth 9 is less than the cross section radius of thin air hose 1.There is piston 10 inside of thick air hose 2, and piston ring 11 tightly contacts with tube wall.Top land 12 has two breach, 13, two breach 13 relative, and the neck 14 of piston 10 (position of cover piston ring) has two notches 15, and notch 15 communicates with breach 13.Be piston rod 17 below the piston 10, piston rod 17 is made up of 4 fins 18.Handle 19 is arranged at piston rod 17 bottoms.Use handle 19 during push-and-pull piston 10.

The lower end of thin air hose 1 is fixed on the end face of thick air hose 2 central lines of these two air hoses.

Earlier valve 3 is inserted in the ball pen during use, and be seated.Be pulled outwardly piston 10 then, piston ring 11 is subjected to the upwards frictional resistance effect of (inwards) of tube wall, makes the piston ring 11 and the bottom surface 16 of piston 10 leave a gap.Along with moving down of piston 10, the interior gas volume of air cavity A (being foregoing first air cavity) increases, and pressure reduces.When gas pressure intensity in the air cavity A during less than 1 atmospheric pressure, ambient atmos (pressure is 1 atmospheric pressure) enters in the air cavity A by above-mentioned gap (gap between piston ring 12 and the piston 11) and the notch 15 of piston neck 14 and the breach 13 of top land 12 under the draught head effect.When piston 10 is pulled to the foot (or bottom) of pipe 2, push inward piston 10 again.When pushing inward piston 10, piston ring 11 is subjected to the frictional resistance effect of outside (downwards) of tube wall, tightly is attached on the bottom surface 16 of piston 10, makes ambient atmos not enter air cavity A by piston 10.Reach along with piston 10, gas volume reduces in the air cavity A, and pressure increases, when pressure greater than the elastic force of spring 5 and air cavity B (foregoing second air cavity) in during gas pressure intensity, gas in the air cavity A is with push rod 6 jack-up, and gas enters in the air cavity B immediately in the air cavity A.Gas density increases in the air cavity B, and pressure increases.Gas enters in the pen core under draught head (air cavity B in gas and the pen core draught head of gas) acts in the air cavity B.Gas density increases in the pen core, and pressure increases.When piston 10 is pulled to extra heavy pipe 2 tops, be pulled outwardly piston 10 again.Because there is round mouth 9 center at the top of extra heavy pipe 2, still have Pneumatic pipe cleaner to cross round mouth 9 above the piston 10 and act on the piston 10, and this air pressure is greater than 1 atmospheric pressure, thereby at this moment be pulled outwardly piston 10 and be easier to.Along with move down (outwards the moving) of piston 10, gas volume increases in the air cavity A, and pressure reduces.When the pressure differential of gas in gas in the air cavity A and the air cavity B during less than spring 5 elastic force, push rod 6 resets under spring 5 elastic force effects, and tightly is pressed on the disk 7 that has through hole 8, will block above the through hole 8.The interior gas of air cavity B can not entered in the air cavity A.When being pulled outwardly piston 11, piston ring 11 is subjected to the upwards frictional resistance effect of (inwards), leaves a gap with piston bottom surface 16.Along with moving down of piston 10, gas volume increases in the air cavity A, and pressure reduces.When gas pressure intensity in the air cavity A during less than 1 atmospheric pressure, ambient atmos (1 atmospheric pressure) enters air cavity A by the gap of 16 of piston ring 11 and piston bottom surfaces and the notch 15 of piston neck 14 and the breach 13 of top land 12 under the pressure differential effect.When piston 10 is pulled to the foot (or bottom) of pipe, push inward piston 10 again.When pushing inward piston 10, piston ring 11 is subjected to the outwards frictional resistance effect of (downwards), tightly is attached on the piston bottom surface 16, and the interior gas of air cavity A can not leaked gas by piston 10, and along with the reach of piston 10, gas volume reduces in the air cavity A, and pressure increases.When gas in gas in the air cavity A and the air cavity B to the pressure differential of push rod 6 during greater than the elastic force of spring 5, push rod 6 overcomes spring force and moves upward under the draught head effect, separate with the disk 7 that has through hole 8, gas enters in the air cavity B by through hole 8 immediately in the air cavity A.In the air cavity B, gas density increases, and pressure increases.Gas enters in the pen core under draught head (air cavity B in gas and the air cavity A draught head of gas) acts in the air cavity B.Gas density increases once more in the pen core, and pressure increases once more.The reciprocating sliding piston 10 like this, and the pen core internal gas pressure is increasing.Be enough to promote when oil column moves forward in the pen core when the pen core internal gas pressure is increased to, oil column moves forward under gas pressure in the pen core, and the oil column that disconnects in the pen core is communicated with, and pen core top and tip do not have the oil place and be full of oil.
