Description

A kind of light pen

Technical field:

The utility model relates to the stationery technical field, refers in particular to a kind of light pen.

Background technology:

A kind of product that can make pen produce light by the light-emitting device that is provided with in the pen on the light pen, it strengthens the aesthetic feeling of pen by the light that self produces, thereby brings the enjoyment of a kind of U.S. of user.General light pen all has two control device, one of them device control circuit of LED closed or disconnect, thus realize the luminous of light emitting diode or extinguish; And another control device is the flexible function that is used to control pen core, make pen core stretch out the shaft of a writing brush in use, otherwise then be retracted in the shaft of a writing brush, its internal structure more complicated of light pen that adopts this mode to make, and it is also comparatively loaded down with trivial details to control product by two control device, brings inconvenience to the user.

On the other hand, in order to satisfy people's demand, a tool manufacturer has made an a kind of tool that has a plurality of different colours pen cores.People can select the pen core of different colours to write in use as required like this.It replaces extending apparatus by one and realizes this purpose, and this upper and lower end that replaces extending apparatus can rotate relatively, and its inside comprises at least two protruded tubes, and the end of each protruded tube is the pen core of fixedly connected different colours all.Make the alternately rotation of the upper and lower end generation certain angle of extending apparatus during use, drive one of them protruded tube and outside device, stretch out, stretch out the shaft of a writing brush, make the user to write thereby drive the pen core that is attached thereto.When needs conversion pen core, continue to make upper and lower end to produce rotation relatively, the then current pen core that is just using is retraction under the protruded tube that is attached thereto drives, and another protruded tube stretches out, and the pen core that promotes another color simultaneously stretches out, realize the different colours pen core alternately.

Summary of the invention:

The purpose of this utility model is to provide a kind of utilization extending apparatus at present alternately, and the two kinds of control device that stretch of light emitting diode folding and pen core are gathered light pen in one.

The utility model is achieved by the following technical solution: its mainly by upper and lower pipe, inner core and alternately extending apparatus constitute, wherein inner core lays respectively at down in the cavity of pipe and last pipe with extending apparatus alternately, alternately the upper and lower end that can rotate relatively in the extending apparatus is fixed with top tube and down tube respectively, and its inner protruded tube has at least one to adopt conductive material to make; Be fixed with battery, light emitting diode and pen core in the inner core of the trend that contracts in the dependence spring keeps; Alternately protruded tube points to an electrode of battery in the extending apparatus, and adopts conductive material making protruded tube to be connected in the loop of battery with the light emitting diode formation.

After adopting this structure, Guan Shi about relative rotation, alternately the two ends up and down of extending apparatus also will produce relative rotation simultaneously, thereby promoting its inner protruded tube stretches out, this protruded tube will promote battery on the other side, thereby promote whole inner core and produce certain displacement, pen core is stretched out, realized the function of refill expansion.In addition, because protruded tube has at least one to adopt conductive material to make, when this protruded tube that adopts conductive material to make supported to the electrode at battery, the circuit of light emitting diode was connected, and light emitting diode is lighted, otherwise then light emitting diode extinguishes.

Description of drawings:

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

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

The specific embodiment:

See accompanying drawing 1, the utility model comprises: on manage 1, manage 2 down, inner core 3, alternately extending apparatus 4, a mouth 5, middle pipe 6 and appliance for holding pen 7.

Inner core 3 lays respectively at down in the cavity of pipe 2 and last pipe 1 with extending apparatus 4 alternately, alternately upper and lower end 41,42 is fixing with last pipe 1 and following pipe 2 respectively in the extending apparatus 4, wherein upper end 41 is fixed by adapter sleeve 11 and last pipe 1, and promptly adapter sleeve 11 fixed covers of inlay card in last pipe 1 are located at alternately 41 places, upper end of extending apparatus 4; With pipe 2 is fixing down, connector 21 fixed covers are located on the lower end 42 by connector 21 in lower end 42, and connector 21 is with pipe 2 is fixing down.When upper and lower pipe 1,2 rotates relatively, alternately the upper and lower end 41,42 of extending apparatus 4 also will rotate simultaneously relatively like this.Alternately the protruded tube 43 of extending apparatus 4 inside has at least one to adopt conductive material to make, and has alternately adopted two protruded tubes 43 in the extending apparatus 4 in the utility model, and one of them adopts conductive material to make, and another adopts insulating materials.

Spring 34 is set on the inner core 3, and its two ends are pressed on down respectively on pipe 2 inwall flanges and the inner core 3 outer wall flanges.Rely on the elastic force of spring 34 like this, inner core 3 will keep the inwardly trend of withdrawal.Inner core 3 comprises battery 31, light emitting diode 32 and pen core 33; Wherein light emitting diode 32 is fixed in the inner core 3 with pen core 33, and in the cavity of battery 31 between inner core 3 and following pipe 2 inwalls.

Replace an electrode of protruded tube 43 sensing batteries 31 in the extending apparatus 4, and it can contact by managing the through hole of offering on 2 tops down with an electrode of battery 31.Adopting conductive material to make protruded tube 431 in addition is connected in the loop of battery 31 and light emitting diode 32 formations.

Mouth 5 is fixed on down the end of pipe 2, and the pen core in the inner core 3 33 points to the through hole of offering in the mouth 5.

Also be arranged with on the shaft of a writing brush 21 and manage 6 in one, between a middle pipe 6 and a mouth 5, be arranged with the appliance for holding pen 7 that a plastic material is made.Appliance for holding pen 7 is by a middle pipe 6 and a mouth 5, and this appliance for holding pen 6 is convenient to the user and is gripped and write.

After adopting this structure, when relative rotation manages 1,2 up and down, alternately the two ends up and down 41,42 of extending apparatus 4 also will produce relative rotation simultaneously, thereby promoting its inner protruded tube 43 stretches out, this protruded tube 43 will promote battery 31 on the other side, thereby promote whole inner core 3 and produce certain displacement, pen core 33 is stretched out by a mouth 5, continue to make and manage up and down when 1,2 generations are relative rotates, protruded tube 43 withdrawals, this moment, inner core 3 resetted under spring 34 promotes, and drove pen core 33 by a mouth 5 withdrawals, thereby had realized the function that pen core 33 is flexible.In addition, because protruded tube 43 has the making of an employing conductive material at least, when this protruded tube 431 that adopts conductive material to make supports extremely on the electrode of battery 31, the circuit communication that battery 31 and light emitting diode 32 constitute, light emitting diode 32 is lighted, and promotes pen core 33 simultaneously and stretch out a mouth 5.Otherwise then light emitting diode 32 extinguishes.Certainly, the utility model can be arranged to as required that pen core 33 stretches out when anticlockwise, but light emitting diode 32 does not work; And when right rotation, pen core 33 stretches out, and light emitting diode 32 is lighted simultaneously.

The utility model is simple in structure, and it has utilized in the existing product alternately extending apparatus 4, has realized two kinds of control device of retractor device of light emitting diode 32 closing devices and pen core 33 are gathered purpose in one, has simplified the internal structure of light pen greatly.
