CN202186159U - External pressing type roller pen - Google Patents

Abstract

The utility model discloses an external pressing type roller pen which comprises a main refill body, a soft refill body and a refill rear end cap, wherein a check valve is arranged at the rear end of the refill for leading air in and preventing the air from flowing out, and the soft refill body is arranged at the front middle part of the main refill body. When the roller pen is used for writing, the main refill body is held by a hand, the soft refill body is pressed, the volume of a through hole inside the main refill body becomes smaller and is pressed, the air inside the main refill body cannot be discharged, the internal pressure is increased, the ink is pressed by the air inside the main refill body to flow out, therefore, the writing is completed; when the soft refill body is not pressed, the soft refill body recovers under the effect of the elasticity, the volume of a through hole inside the main refill body becomes larger, the internal pressure is decreased, a rubber ball is detached from a valve slot, and the air can enter the inner part of the through hole of the main refill body for replenishing air. The external pressing type roller pen is suitable for writing in various states of the main refill body.

Description

The external-compression type signature pen

Technical field

The utility model relates to the attending classes articles for use, relates in particular to a kind of pen of writing usefulness.

Background technology

When calling front end to the pen tip of writing the pen core of usefulness, just can be call the pen core rear end away from pen tip.Automatically down water-color paintbrush is that a water is flowed out, and reaches the purpose of writing, and this just requires when using pen to write, should make pen tip be lower than the pen core rear end, can flow out at the component effect of the gravity water of starting writing.When pen tip was not less than the pen core rear end, a water just can not flow out, and did not reach the purpose of writing.A water of the utility model can flow out under the effect of external force, therefore, can not need under the effect of gravity, flows out, and therefore, the external-compression type signature pen of the utility model also can be accomplished writing task when pen tip exceeds the pen core rear end when writing.

Summary of the invention

The purpose of the utility model is, when writing, the pen core main body is under degree of tilt arbitrarily, and just the two of pen tip and pen core rear end can both be accomplished writing task highly arbitrarily under the state.

To achieve these goals, the utility model adopts following technical scheme:

A kind of external-compression type signature pen; Be made up of pen core main body, nib, nib, pen core software, pen core rear end cap, it is characterized in that: the pen core rear end cap is embedded in the rear end of pen core main body, and the middle front part of pen core main body has the pen core software; The front end of pen core main body embeds nib, and nib is pressed into the nib head.

According to described external-compression type signature pen, it is characterized in that: described pen core rear end cap plays the effect of check valve, is made up of pen core rear end cap main body, venthole, groove, valve pool, ball.

According to described external-compression type signature pen, it is characterized in that: described pen core main body, middle front part has the pen core software, and the inside of pen core main body is through hole.

According to described external-compression type signature pen, it is characterized in that: described through hole divides pen core metapore, pen core mesopore, the preceding hole of pen core, stopping footpath four parts, is used to deposit a water.

In the accompanying drawing: 1, pen core main body; 2, nib; 3, nib; 4, pen core software; 5, pen core rear end cap; 6, pen core metapore; 7, pen core mesopore; 8, the preceding hole of pen core; 9, pen core rear end cap main body; 10, venthole; 11, groove; 12, valve pool; 13, ball; 14, stopping footpath.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.

The external-compression type signature pen of the utility model; Like accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, comprising the preceding hole of: pen core main body 1, nib 2, nib 3, pen core software 4, pen core rear end cap 5, pen core metapore 6, pen core mesopore 7, pen core 8, pen core rear end cap main body 9, venthole 10, groove 11, valve pool 12, ball 13, stopping footpath 14.

Assembly relation:

Nib 2 is embedded in the front end of pen core main body 1, and nib 3 is pressed in the nib 2, and the middle front part of pen core main body 1 connects pen core software 4; Sealed attachment; Pen core rear end cap 5 is pressed into pen core main body 1, cooperates with stopping footpath 14 through groove 11, plays fixation; The inside of pen core main body 1 is through hole; Through hole divides the preceding hole of pen core metapore 6, pen core mesopore 7, pen core 8, stopping footpath 14 4 parts, and pen core rear end cap 5 is made up of pen core rear end cap main body 9, venthole 10, groove 11, valve pool 12, ball 12, the formation check valve.

The utility model has the advantages of:

The utility model external-compression type signature pen, a water flows out through the effect of external pressure, can be not effect through gravity; Therefore, when writing, the pen core main body can be in arbitrary angle; The height of pen tip can be higher than the height of pen core rear end, can both accomplish writing task.

The design principle of the utility model is following:

The utility model external-compression type signature pen, the pen core rear end cap plays the effect of check valve, when writing, holds the pen core main body; Push the pen core software, the interior volume of through hole of pen core body interior is diminished and pressurized, make ball be pressed towards valve pool, stop up venthole; Pen core main body through hole gas inside can not be discharged, inner pressure is increased, under the pressure action that increases, a pen core main body through hole gas inside compressing water; When writing, a water is flowed out, accomplish writing task; When not pushing the pen core software, the pen core software is pressurized not, and under the effect of elastic force, recovers, and makes the inner volume of pen core main body through hole become big, and pressure diminishes, and the ball of this moment breaks away from valve pool, and it is inner that gas can get into pen core main body through hole, make-up gas; The pen core rear end cap has the effect of check valve.
