Abstract

The utility model relates to a luminous pen cap which plays the lighting action when people write at night. The utility model is characterized in that a power supply circuit composed of a positioning plate, a spring, a slice-type battery, a pen clamp, a lighting diode, etc. is arranged in the upper part of the pen cap, and the uplifting and the falling operation of the pen can play the function in switching on and off the battery. The utility model can be widely used in a fountain pen and can provide illumination when people write at night, thus providing convenience for people.

Description

Luminous pen cap

The utility model is a kind of Luminous pen cap, exactly is a kind of Luminous pen cap that can help the person of writing to throw light at night.

At present the pen that uses does not all have the night illumination effect, so when using the people of pen to write as in the night, often can't write owing to there is not light to throw light on or the grass that made the writing that writes out.

The purpose of this utility model, exactly at the problems referred to above for people provide a kind of new-type cap for brush, make it when people use this cap for brush to be enclosed within to write on the pen night, can access the light illumination.

The utility model mainly is that new design has been carried out on cap for brush top, location-plate 14 is taken and is placed on the boss deck 2, one screw 3 is arranged in the middle of the location-plate 14, fix a spring 4 by it, place single piece type battery 11 on the spring 4, pen clip 9 and bearing pin 5 are hinged on the top of the cap for brush, and pen is an insulating bodies, but contact 1 and the contact 2 stretched in the cap for brush all are electrical conductors, the two ends of light emitting diode link to each other with contact 2 with contact 1 respectively by lead, contact 1 is pressed on the chip battery all the time, on the top of the cap for brush, and the front end of contact 2, contact, one metal inclined-plane 8 is arranged, just contact with contact 2 when this inclined-plane has only pen clip to lift, and circuit is connected, light emitting diode 12 is luminous.

The utility model can be widely used on the pen after realizing, when writing night, lifts the pen clip luminous tube and just sends light, and the person of writing can write easily by this light, for people provide more convenience.

Description of drawings: Fig. 1 is a cap for brush internal structure schematic diagram of the present utility model; Fig. 2 is a circuit diagram of the present utility model.Among the figure, 1-pen, 2-boss deck, 3-screw, 4-spring, 5-bearing pin, 6-contact 2,7-top cap, 8-ramp contacts, 9-pen clip, 10-contact 1,11-chip battery, 12-light emitting diode, the 13-cap for brush, 14-location-plate.

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

The cap for brush 13 of the present utility model should grow 1/3 than the cap for brush commonly used in the past, and design a circular platform 2 at 1/3 place, distance upper end, there is a screw centre of location-plate 14 and fixes a spring 4, chip battery 11 should be selected 3 volts for use, do not have as market, also can select for use 2 1.5 volts battery to be connected in series, pen clip 9 should select for use insulating materials to make, but contact 1 and contact 2 also must be electrical conductors, and the angle of contact 1 → bearing pin → contact 2 should equal 90 degree, contact, inclined-plane 8 in design, should select metallic conductor, and should weld between it and the cap for brush and be one, when lifting pen clip, it is promptly luminous that circuit is connected diode, when pen clip playbacks, contact 2 disconnects with inclined-plane conductor 8, even entire circuit disconnects, diode is not luminous.

Claims

A kind of Luminous pen cap that is exclusively used in the illumination of writing night is characterized in that: in the middle of the location-plate 14 in the cap for brush screw 3 is arranged, fix a spring 4 by it, place single piece type battery 11 on the spring 4; Pen clip 9 and bearing pin 5 are hinged on the top of the cap for brush, and pen clip is an insulating bodies, but contact 1 and the contact 2 stretched in the cap for brush all are electrical conductors, and the two ends of light emitting diode link to each other with contact 2 with contact 1 respectively by lead; Contact 1 is pressed on the chip battery all the time, and on the top of the cap for brush, the front end of contact 2 has contact, a metal inclined-plane 8, and this inclined-plane only when pen clip lifts, just contacts with contact 2, and circuit is connected.
