Description

One kind writing Nearsightedness-preventing pen

Technical field：

The utility model belongs to Writing instrument field, more particularly to a kind of writing Nearsightedness-preventing pen, in particular by low level electricity The Nearsightedness-preventing pen of cell cavity design.

Background technology：

With the development of microelectronics, significant progress also occurs for electronics Nearsightedness-preventing pen last decade, and it is on penholder top from upper Battery, upper axle bed, the circuit board with infrared sensor, actuation coil, lower axle bed and throw-out lever are sequentially distributed under and；Student makes With this writing process, when face gets too close to desktop, at this moment built-in infrared induction circuit is anti-by face with regard to that can receive The signal come is emitted back towards, is dealt with by circuit judges, control coil is powered or power-off, coil electricity produce magnetic field suction thrust Magnet on bar makes throw-out lever up tilt, and at this moment pen core is just retracted upwards in the case of no rear support power, and the pen is with regard to nothing Method is write, and forms myopic-preventing protection；When desktop leaves to certain distance in face, then throw-out lever resets, and has support at the top of pen core It just can normally be write after power, reach pre- myopic-preventing effect.

At present, the battery of such Nearsightedness-preventing pen is installed in pen arm end, changes battery for convenience, is set in pen arm end It is equipped with a cap for brush.Due to high density button weight weight, somewhat top-heavy sense when holding a pen, the especially small strong point of student's palm is inclined It is low, it is this to feel to become apparent.How to improve the deficiency of existing Nearsightedness-preventing pen, become the object of the utility model research.

The content of the invention：

The purpose of this utility model is the writing Nearsightedness-preventing pen that a kind of battery compartment of design is arranged between lower axle bed and coil.

What technical solutions of the utility model were realized in：One kind writing Nearsightedness-preventing pen, includes penholder, pen cap, pen Head and pen core；Penholder top is sequentially distributed upper axle bed, the circuit board with infrared sensor, lower axle bed, actuating wire from top to bottom Circle and throw-out lever；It is characterized in that：Battery compartment is provided between lower axle bed and actuation coil, the battery two in battery compartment It is extremely corresponding to be electrically connected with lower axle bed and upper axle bed.

The lower axle bed and actuation coil are arranged on a core print seat plastic, the core print seat plastic lower axle bed and actuation coil it Between battery compartment is set, the battery compartment be through penholder axis longitudinal grooved, be provided with an elongated slot middle side part of fluting negative Pole lead, negative pole stage portion is provided at both ends with, a short groove side of fluting is provided with positive wire.

The penholder includes Pen-holder sleeve and penholder core, and penholder core is made up of transparent sheath and core print seat plastic, and core print seat plastic plugs In transparent sheath bottom；Upper axle bed and circuit board with infrared sensor are arranged in the transparent sheath, and penholder core is by transparent sheath Lower end is plugged in the Pen-holder sleeve upper end, and the infrared sensor on holding circuit plate exposes outside.

The battery bin location that the Pen-holder sleeve corresponds to core print seat plastic offers gathering hole, and the gathering hole is configured with a lid.

A decorative ferrule is provided between the transparent sheath of Pen-holder sleeve and the penholder core, the decorative ferrule activity is embedded saturating Bright to put, displacement can block the joint portion of transparent sheath and Pen-holder sleeve downwards, and keep off toward outside the battery compartment of core print seat plastic.

The utility model moves down battery compartment, has the advantages that：1st, penholder decentralization, it is more sane to hold a pen；2、 Infrared sensor moves up, and closer to face, reduces sense blind area, reaction is more sensitive；3rd, it is convenient to assembling and the later stage changes electricity Pond operates, and the transparent sheath bottom of penholder only needs fit on axle bed, and when changing battery, need to only open lid or by penholder Core pulls out one section, you can operation.
