Abstract

The invention discloses a metering correction pen which comprises a pen nib, a pen cap and a liquid storage cylinder, wherein the pen nib is mounted at an open end of the liquid storage cylinder, a liquid outlet hole is arranged at the top of the pen nib, and the liquid outlet hole is connected with the rear liquid storage cylinder through a pipeline in the pen nib. The invention is characterized in that a piston and a piston pushing mechanism are also arranged in the liquid storage cylinder. The metering correction pen provided by the invention effectively realizes the control of the outflow amount of correction liquid, and corrects writing errors by using the tabular pen nib in a stamped way without smearing, thereby effectively improving the using quality of the correction pen.

Description

The metering-type correction pen

Technical field

The present invention relates to a kind of correction pen.

Background technology

People some clerical errors can occur unavoidably in writing the article process, so the revisal of normal use truing tool.Truing tool commonly used just comprises correction pen.

Known pen type opaquing fluid, nib and the surge drum by the pin lip pencil constitutes usually, and opaquing fluid is coated in clerical error by the output of nib place micropore with opaquing fluid, by the curing of opaquing fluid, realizes the correction to the clerical error place.The penholder of correction pen normally is made of plastics, and during use, can utilize the elasticity of plastic penholder to realize the opaquing fluid that is stored in the penholder is pushed and the outflow of realization opaquing fluid.Yet because this extruding force depends on user's sensation control fully, therefore, this correction pen in use tends to occur cause the too much phenomenon of fluid too greatly because of extruding force.

Summary of the invention

The objective of the invention is at above-mentioned technological deficiency, provide a kind of utilization control to the opaquing fluid squeezing pressure, the new technical scheme of achieve effective control opaquing fluid water flow is to reach the result of use of improving correction pen.

The present invention realizes by following manner:

A kind of metering-type correction pen comprises nib, the cap for brush, surge drum, and wherein nib is installed on the openend of surge drum, fluid hole is established on the top of nib, fluid hole links to each other with the surge drum at rear portion by written internal pipeline, it is characterized in that, also is provided with piston and piston propulsive mechanism in the surge drum.

Described piston propulsive mechanism is made of craspedodrome pushing ram, rotation pushing ram, tube connector, square bar, metering ratchet, spring, bonnet, nib, a prominent head is established on wherein the keep straight on top of pushing ram, piston is installed on this prominent head, and the rear end is a cavity, in establish silk mouthful; The front end outer wall of rotation pushing ram is provided with and the silk mouth that advances screw mandrel to cooperate, and is inserted in the rear end cavity of pushing ram, and the rear end of rotation pushing ram is the rectangular enclosure axle; The axis of tube connector is an air-cored axis, and the end face of one end is provided with ratchet, and the two ends of square bar are rectangle, and the middle part is a circular shaft, assigns on the tube connector; The metering ratchet also is the sleeve of a hollow, establishes ratchet on the end face of an end, cooperates with the ratchet of tube connector end face; One end of square bar passes the metering ratchet, is fixed on the rear end of rotation pushing ram again, and spring is installed on the other end of square bar, and bonnet is bonded in the not end of square bar;

The outer wall of described craspedodrome pushing ram is provided with slideway, correspondingly, is provided with the chute that cooperates with the outer wall slideway of the pushing ram of keeping straight on described surge drum inwall;

Described nib is flat;

Also be provided with in the described cap for brush and seal pin.

Because the present invention has realized the liquid outlet quantity control of opaquing fluid effectively, and utilizes flat nib, in a kind of mode of impressing, revise and do not need to smear writing error place, improved the service property (quality) of correction pen effectively.

The specific embodiment

Use rigid plastics,,, obtain each required part of correction pen, successively each part is assembled into one by the structure shown in the accompanying drawing 1 again according to each shape shown in the drawings in the mode of casting.

Wherein nib 3 is installed on an end of surge drum 8 by nib seat 4, fluid hole is established on the top of nib 3, fluid hole links to each other with the surge drum 8 at rear portion by written 3 internal pipelines, also is provided with piston 5 and piston propulsive mechanism in the surge drum 8, and seal with cap 1 on the top of nib 3 again.

Because present opaquing fluid that uses or the solid type of light, or the solvent evaporates type, expose in the air and very easily solidify, therefore, in cap 1, establish nadel 14, make it after cap 1 closes as sealing pin 2, seal pin 2 and insert in the fluid hole of nib 3, realize sealing.

Surge drum 8 utilizes rigid plastics to make, and therefore the opaquing fluid in the tube need flow out by pressurization.Realize this goal by set up a piston propulsive mechanism at surge drum 8 among the present invention, the piston propulsive mechanism is made of craspedodrome pushing ram 6, rotation pushing ram 7, tube connector 11, square bar 9, metering ratchet 12, spring 10, bonnet 1313, wherein the keep straight on top of pushing ram 6 is established prominent 17, piston 5 is installed on this prominent 17, the rear end is a cavity, in establish the silk mouthful; The front end outer wall of rotation pushing ram 7 is provided with and the silk mouth that advances screw mandrel to cooperate, and is inserted in the rear end cavity of craspedodrome pushing ram 6, and the rear end of rotation pushing ram 7 is the rectangular enclosure axle; The axis of tube connector 11 is an air-cored axis, and the end face of one end is provided with ratchet 19, and the two ends of square bar 9 are rectangle, and the middle part is a circular shaft, assigns in the air-cored axis of tube connector 11; Metering ratchet 12 also is the sleeve of a hollow, establishes ratchet 20 on the end face of an end, cooperates with the ratchet 19 of tube connector 11 end faces; One end of square bar 9 passes metering ratchet 12, is fixed on the rear end of rotation pushing ram 7 again, and spring 10 is installed on the other end of square bar 9, and bonnet 13 is bonded in the not end of square bar 9.

In order to guarantee the pushing ram 6 maintenance craspedodrome state when working of keeping straight on, the outer wall of craspedodrome pushing ram 6 is provided with slideway 16, correspondingly, is provided with the chute 18 (as accompanying drawing 4,6) that cooperates with the outer wall slideway 16 of the pushing ram 6 of keeping straight on described surge drum 8 inwalls.

Of the present invention written 3 make tabular, when making the opaquing fluid water outlet, form plane distribution.

During use, as long as pass through rotation bonnet 13, measure ratchet 12 and can send a sound, show that craspedodrome pushing ram 6 has advanced a unit, can extrude the plane of a quantitative opaquing fluid in nib 3, nib 3 is directly printed to be placed on needs the correction part to get final product.
