Abstract

A silent ball-point pen relates to an improvement for a ball-point pen in structure. The utility model provides a silent ball-point pen which is simple in structure and convenient in use, and does not influence other people. The silent ball-point pen provided by the utility model comprises a pen tube, wherein a refill is arranged in the cavity of the pen tube. The silent ball-point pen is characterized in that: an electromagnet is arranged at the upper end of the refill, and the electromagnet is composed of metallic iron and a coil outside the metallic iron; the coil is serially connected with a power supply in the pen tube and a thermoswitch outside the pen tube; and a permanent magnet is arranged on an upper part in the cavity of the pen tube corresponding to the metallic iron, and a limit stopper is arranged below the metallic iron in the cavity of the pen tube.

Description

Noiseless ball pen

Technical field:

Noiseless ball pen, (IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and big type of office appliance is write or the drawing appliance group ball pen technical group field.In particular, relate to a kind of improvement of ball-point pen structure.

Background technology:

At present, the technology about ball pen existing and that once had has been made very fruitful effort to noiseless ball pen, also once designs many outstanding technical schemes.Like being declared by Dong Zhennan of the Decree of Patent Office of China in 2006, Granted publication number is CN 2749691, and Chinese patent number is: No. 200420066542.0 utility model, title are the utility model patents of " novel ball-point pen ", the technical scheme that is adopted.At the technical elements of ball pen, be of great value innovation and creation, it is made up of a nose, fixed bar, top, opaquing fluid, clamp, snap ring.Adopt the both sides of opaquing fluid to clamp the inboard that is connected clamp; Two outsides gummed of clamp is connected the inboard, top of penholder; The nested end that is connected Spring Card in top of nose; Nested top one side that is connected penholder of the other end of Spring Card, the nested technical scheme that is connected the centre of snap ring in the bottom of fixed bar solves the problem that ball pen in the past can not be revised writing.But, also have many deficiencies:

It can't solve when automatic ball pen is pressed has sound, influences the problem of other people study.

Summary of the invention:

The utility model is exactly to the problems referred to above, provides a kind of simple in structure, easy to use, does not influence other people noiseless ball pen.

For reaching the above-mentioned purpose of the utility model, the utility model adopts following technical scheme, and the utility model comprises the shaft of a writing brush, is provided with pen core in the cavity of the shaft of a writing brush; It is characterized in that: the upper end of pen core is provided with electromagnet, and described electromagnet is made up of metallic iron and the outer coil of metallic iron; Described coil is with power supply in the shaft of a writing brush and the outer thermoswitch polyphone of the shaft of a writing brush; The cavity internal upper part of the shaft of a writing brush is provided with permanent magnet corresponding to metallic iron, and the below of metallic iron has been provided with limiting block in the cavity of the shaft of a writing brush.

Described power supply is connected in series by five button cells.

The beneficial effect of the utility model:

1, simple in structure:

Be provided with pen core in the cavity of the shaft of a writing brush of the utility model; The upper end of pen core is provided with electromagnet, and described electromagnet is made up of metallic iron and the outer coil of metallic iron; Described coil is with power supply in the shaft of a writing brush and the outer thermoswitch polyphone of the shaft of a writing brush; Be provided with permanent magnet corresponding to metallic iron in the cavity of the shaft of a writing brush, the below of metallic iron has been provided with limiting block in the cavity of the shaft of a writing brush.Its member is few, and the utility model is simple in structure thus.

2, easy to use:

When the utility model uses, need not to press button, only need will hold on the thermoswitch, switch is communicated with electromagnet and produces magnetic, repels with permanent magnet, and the nib of pen core is stretched out by shaft of a writing brush front end; Method of operating is simple, and is easy to use.

3, noiseless, do not influence other people study:

The button that existing ball pen uses has been omitted in the turnover of the utility model through the high-speed double electromagnet nib, has avoided pressing button and the sound that sends; Do not influence other people study.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the circuit theory diagrams of the utility model.

1 is that the shaft of a writing brush, 2 is that thermoswitch, 3 is that pen core, 4 is that cavity, 5 is that metallic iron, 6 is that coil, 7 is that electromagnet, 8 is that permanent magnet, 9 is that power supply, 10 is a limiting block in the accompanying drawing.

The specific embodiment:

The utility model comprises the shaft of a writing brush 1, is provided with pen core 3 in the cavity 4 of the shaft of a writing brush 1; It is characterized in that: the upper end of pen core 3 is provided with electromagnet 7, and described electromagnet 7 is made up of metallic iron 5 and metallic iron 5 outer coils 6; Described coil 6 is contacted with power supply in the shaft of a writing brush 19 and the shaft of a writing brush 1 outer thermoswitch 2; Be provided with permanent magnet 8 corresponding to metallic iron 5 in the cavity 4 of the shaft of a writing brush 1, the below of the cavity 4 internal upper part metallic irons 5 of the shaft of a writing brush 1 has been provided with limiting block 10.

Described power supply 9 is connected in series by five button cells.

By the power supply 9 that five button cells constitute, voltage is high, guarantees the stable of nib.

Above content is the further explain that combines concrete preferred implementation that the utility model is done; The practical implementation that can not assert the utility model is confined to these explanations; Those of ordinary skill for technical field under the utility model; Under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the definite protection domain of claims that the utility model is submitted to.
