Description

Can seal off the pen that adds water

Technical field

The utility model relates to a kind of pen, exactly is to seal off the pen that adds water.

Background technology

The existing pen that adds water of can sealing off be because will consider the requirement of product sealing function, so that accessory cooperates is tight slightly, it is big, very inconvenient to seal off difficulty, when ink uses up need add water the time, need remove to turn the back plug arduously with hand, and ink is sticked on hand.

The utility model content

At the deficiency that prior art exists, the purpose of this utility model be to provide a kind of easy to use, seal off and can seal off the pen that adds water easily.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of pen that adds water of sealing off comprises the cap for brush, fiber head, rolled core, penholder and back plug, and the described cap for brush is provided with projection in the top, and back plug afterbody end is provided with this projection inlays the groove that spline cooperates.

Described projection and groove are cross, triangle or polygon.

Described projection and groove matched in clearance.

Described back plug cooperates with the helixseal of penholder rear end.

The utility model uses up need add water the time at ink, only need pull out the cap for brush, the groove fit that its projection and back are matched, rotate the back and just can screw down the back plug, rolled core is added water after, again will the back fill in to screw and just can write, as a bottle opener that carries, very convenient, avoided directly twisting the back plug like that firmly with hand, can prevent that also turning on plug back, back with hand contacts with residual ink and ink is sticked on hand.

Description of drawings

Fig. 1 is a schematic cross-section of the present utility model;

The structural representation that Fig. 2 matches with the back plug for the cap for brush.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---the cap for brush

2---fiber head

3---rolled core

4---penholder

5---the back plug

6---projection

7---groove

As shown in Figure 1 and Figure 2, this can be sealed off the pen that adds water and mainly be made up of the cap for brush 1, fiber head 2, rolled core 3, penholder 4 and back plug 5, the cap for brush 1 is outside the function of original sealing nib, also be provided with cross projection 6 in its top, back plug 5 is provided with this projection at its afterbody end inlays the groove 7 that spline cooperates, projection 6 and groove 7 matched in clearance, back plug 5 cooperates with the rear end helixseal of penholder 4, can utilize the cap for brush 1 as bottle opener, the back plug 5 of outwarding winding easily easily screws after adding water again again.Certainly, projection 6 also can be triangle, polygon etc. with the shape of groove 7 and can cooperate and turn the shape that can't rotate.

This technical scheme is under the prerequisite that can add water function, consideration requires (accessory cooperates tight slightly) because of the product sealing function, it is big, inconvenient to seal off difficulty, through function design cleverly, can seal off easily, reach the purpose that adds water, made things convenient for consumer's use, compared with existing added aquatic products of the same type, under the prerequisite that does not increase cost, carry out appropriate design from structure function, use more convenient, lighter.

The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
