Description

Portable durable blackboard pen

Technical field

The utility model relates to the blackboard pen or claims the oil pen, is a kind of portable durable blackboard pen.

Background technology

The blackboard pen is a kind of oil pen who is used to write, and its printing ink is oiliness, is insoluble in water, not fugitive color with melt.This type of blackboard pen does not produce chalk dust when writing owing to it, and uses with blank gradually, replaces blackboard and chalk in the existing teaching, thereby is widely used in the character calligraph in places such as teaching and speech.But because its inner chamber printing ink limited storage space, even through inner chamber the volatilization that printing ink core mode reduces, reduces printing ink is set, its printing ink volatilization is still very fast, and drying and can't writing is brought more inconvenience to the user easily.For this reason, like the ZL patent No. 96242176.6 that discloses in the Chinese patent document, October 15 1997 Granted publication day, utility model title " a kind of durable blackboard pen "; It is characterized in that being provided with the shaft of a writing brush in the middle of the pen core in a body cavity, the said shaft of a writing brush is provided with through hole all over the body, and the end face of its end is provided with through hole and is connected with the nib that stretches into pen core, and the other end is connected a body tail end, which is provided with the pen plug of sealing; This durable blackboard pen can add ink repeatedly and use long service life.But above-mentioned blackboard pen also realizes that through filling printing ink it continues the purpose of using, and difficult under the situation that lacks printing ink, fills printing ink temporarily.

Summary of the invention

For overcoming above-mentioned deficiency, the purpose of the utility model is to this area a kind of portable durable blackboard pen that carries printing ink rubber bottle to be provided, and makes it solve the interim comparatively technical problem of inconvenience of filling of existing like product printing ink.Its objective is and realize through following technical scheme.

A kind of portable durable blackboard pen is provided with interior pipe in the body of this blackboard pen, and a body one end that communicates with interior pipe is provided with pen core, and a body of the interior pipe other end is provided with pen tail cap; Be provided with the printing ink core in the interior pipe of body, pen tail cap is threaded with a body, and the pen core end of a body and the cap for brush fasten; This blackboard pen is identical with existing blackboard pen, is that pen core provides printing ink by the printing ink core of pipe in the body, pen tail cap is connected with a body thread seal prevent in printing ink volatilization in the pipe, the printing ink a when body and cap for brush fastening prevent that pen core from not using volatilizees.Pen tail cap adopts elastomeric material to process.Its structural design main points are to be provided with the rubber bottle in the pen tail cap between said body and the pen tail cap, and the orifice of rubber bottle one end closes with the inner orifice muzzle of a body, and orifice stretches into interior pipe.Printing ink is stored in the rubber bottle, and as the subsequent use ink bottle of interim filling printing ink, the rubber bottle can use repeatedly.Promptly when the printing ink in the body was not enough, through pushing pen tail cap, the stressed generation deformation of rubber bottle that pen tail cap and pen tail cap are interior was managed and the printing ink core in the interior printing ink of rubber bottle injects through orifice, is packed into new ink.

The inner orifice mouth of said body is provided with deep-slotted chip breaker, and the orifice end of rubber bottle is provided with arcwall face, the deep-slotted chip breaker fit of the arcwall face of rubber bottle and interior pipe.Applying and the orifice positioning and guiding between rubber bottle and the interior pipe is convenient in arcwall face groove design, combines being threaded between pen tail cap and the body to prevent that printing ink is excessive in interior the pipe simultaneously.

When being convenient to the printing ink deficiency, the utility model fills temporarily, its reasonable in design, and easy to use, good sealing effect; Be suitable as similar oil pen's uses such as blackboard pen, and the architecture advances of like product.

The specific embodiment

Combine accompanying drawing at present, to the structure of the utility model with make as further describing.Like Fig. 1～shown in Figure 3, pipe 103 in being provided with in the body 1 of this blackboard pen, interior pipe communicates with the pen core 101 of a body one end, and the other end of a body is provided with pen tail cap 3, is provided with printing ink core 102 in the interior pipe, and pen tail cap is threaded with a body; Be provided with rubber bottle 2 in the pen tail cap between body and the pen tail cap, the orifice 201 of rubber bottle one end and the interior pipe 103 aperture fits of a body, orifice stretches into interior pipe.Inner orifice mouth between a rubber bottle and the body is provided with deep-slotted chip breaker 104, and the orifice end of rubber bottle is provided with arcwall face 202, the deep-slotted chip breaker fit of the arcwall face of rubber bottle and interior pipe.

As shown in Figure 3, this blackboard pen is identical with the occupation mode of existing blackboard pen, opens the cap for brush, can write in blank through the pen core of a body.But; When this blackboard pen does not have printing ink, be provided with the rubber bottle of band printing ink in the pen tail cap of this blackboard pen, through taking out the rubber bottle orifice of rubber bottle is alignd with the interior pipe of a body; Or directly push pen tail cap, the subsequent use printing ink in this rubber bottle can inject in the interior pipe of a body.Because its subsequent use printing ink is stored in the rubber bottle, its volatilization effect a little less than, the printing ink of pipe can be preserved the time than length in the printing ink in the rubber bottle was compared.
