Description

Multipurpose writing pen with illuminating unit

The utility model belongs to illumination and writes the multipurpose pencil class, relates to the combination of lighting source and different parts of writing pen two classes and technology.The technology that is specifically related to is: in the written proper site that adopts transparent material to make.Be provided with and be no less than 1 illuminator at least, be furnished with power supply and other part in addition in the penholder, and each is reasonably connected between part in addition.

In order to solve the problem of writing in insufficient light or dark occasion, Chinese patent has been announced " a kind of writing appliance with illumination " for No. 86201524, this patent adopts a kind of small electric bulb and reflection shield that a protrusion is set at the penholder middle part, and the method that light is shone the nib place reaches the purpose of writing in above-mentioned occasion.Its shortcoming of this writing appliance is:

1. because of reflection shield being arranged, the ridge that small electric bulb is formed.There is not pen clip again, so carry inconvenience.

2. small electric bulb is far away from the nib place, have " enough light concentrates on and writes the place " must adopt volume and the bigger small electric bulb of light intensity, and its battery power consumption is big, and the life-span is short.

3. the most copper-iron piece that adopts of structure makes this writing implement cost height, and it is many to expend copper material, and weight is big, long and complex process of manufacturing cycle.

4. can not write in the time of need not throwing light on, because of moving axially of pen core do not obtain restriction.

It is a kind of in insufficient light or complete dark environment that the purpose of this utility model is to provide, the light that sends with the illuminator of written proper site setting, can replace flashlight lighting, can in illumination, write, in the time need not throwing light on, do conventional pen again and use.Need not the pen cap, do not change the form and the using method of conventional pen, multipurpose pencil is write in a kind of illumination that can be convenient for carrying.

The center technical problem that the utility model solved is the head proper site at multipurpose pencil, and a plurality of illuminators are set as required, and illuminator sends enough strong light directly according to object or thing to be written.Power supply is arranged in the penholder, pen clip double as power switch, and the structure of conventional pen combined with used electric component, means of illumination is equally applicable to various writing pens.

This utility model is compared with original technology, have no shadow shape, the no pen cap, illumination is soft, bright and clear, light loss is few, means of illumination is equally applicable to various writing pens advantage, and can replace flashlight lighting, be easy to carry, can use in all cases, whole pen is in light weight, manufacturing is simple, cost is low.

Below with reference to accompanying drawing and infinite embodiment, the utility model is described in further detail.

Description of drawings:

Fig. 1 is the longitudinal sectional view of a kind of concrete structure of the present utility model.

With reference to Fig. 1, refill for ball-point pen (3) is loaded in the plastic penholder (4) together with refill expansion mechanism (5), nib (1) adopts with penholder (4) and is threaded, several little small electric bulbs (2) are set in transparent plastic nib (1) as required, two leads of little small electric bulb (2) are connected with inside and outside becket (14), (13) respectively, are bar shaped lining one conductive layer at inside to the head external screw thread place of penholder (4).This conductive layer one end and interior becket (14), the other end and power spring seat (12) are connected, and power spring seat (12) is connected into an anodal conducting wire with spring (6), conducting strip (7) until the positive pole of battery (9).Establish the circumferential groove of an axial notch and pen clip end connects in penholder (4) appearance, also lining one conductive layer in the groove, this conductive layer one end and outer becket (13), the other end is connected with conduction pen clip (8), the tail end end face junction of pen clip (8) and penholder (4) metal spring leaf (11) of packing into, metal spring leaf (11) keeps Elastic Contact with the shell negative pole of battery (9) all the time, and this just is connected into one by the conducting wire of little small electric bulb (2) to battery (9) negative pole.

In Fig. 1 concrete structure, the end face of penholder (4) and refill expansion mechanism (5) glues together with binding agent, in order to avoid pen core (3) axial float when writing.Power spring seat (12) should keep Elastic Contact closely with penholder (4) inwall conductive layer, to guarantee good conductive, referring to enlarged drawing (II).The part that penholder (4) is not exposed on battery (9) surface adopts thicker plastic wraps layer.Its end face is axially movable spacing as battery (9).Referring to enlarged drawing (III).Metal spring leaf (11) has several clubfoots and contacts with GND.Correspondingly have several grooves that the spring pin is just in time embedded in the groove in the end of pen clip (8), referring to enlarged drawing IV and K to figure.The conductive layer of plating 1/4 girth in the circumferential groove on the penholder (4) makes the pen clip energy of rotation make switch and uses.

Because illumination can divide, can close again with the use of writing, so need write the time, press battery (9) afterbody battery (9) is moved axially to pressing bar (10), bar (10) is pressed in promotion makes pen core (3) stretch out nib.Need illumination then to rotate pen clip (8) and makes power connection, if need not, press the afterbody of battery (9) again, make and press bar (10) and reset, then in the pen core indentation pen.Need turn off the light, backward rotation pen clip (8) gets final product.If change pen core (3), can screw off nib (1), transfer to pen core.If change battery (9), the pen clip (8) of axially backing off gets final product.

Claims (3)

1, is connected with nib (1) by illuminator (2), multipurpose pencil is write in the illumination that power supply (9) and pen core (3) are housed in the penholder (4), it is characterized in that being no less than little small electric bulb (2) of 1 at least in nib (1) proper site setting, two leads of little small electric bulb (2) link to each other with inside and outside becket (14), (13), and interior becket (14) passes through penholder (4) and goes up the conductive layer of lining, power spring seat (12), spring (6), conducting strip (7), is connected with battery (9) is anodal; Outer becket (13) by conductive layer, the conduction pen clip (8), and metal spring leaf (11) be connected with battery (9) negative pole.

2, multipurpose pencil is write in illumination according to claim 1, it is characterized in that conducting electricity that the conductive layer of lining 1/4 girth contacts in the circumferential groove on pen clip (8) one ends and the penholder (4), the other end is connected with metal spring leaf (11), and rotation pen clip (8) is switched on or switched off pen clip and conductive layer circuit.

3, multipurpose pencil is write in illumination according to claim 1, it is characterized in that battery (9) surface do not expose the part of penholder (4) and adopt thicker plastic wraps layer, its end face axially movable spacing as battery (9), battery (9) moves axially, and promotes to press bar (10) and makes refill expansion.
