Abstract

The utility model provides an optical pen structure, includes a pen body and a pen head, a concave spherical bearing socket is positioned on one end of the pen body, and a spheriform pen head is arranged on the bearing socket, one part of the pen head protruding the bearing socket, periphery of which is deformed with pressure adding so that the pen head is fixed, the combination of the pen head and the pen body without using adhesive agent, is more durable.

Description

The optical pen structure

Technical field

The utility model relates to a kind of optical pen that is used in such as PDA information products such as (individual digital action assistants, or title palmtop computer).

Background technology

Because the prosperity of scientific and technical information industry, the use of PDA is also more and more general, uses the convenience of PDA to be that it can utilize light pen to come information on the taps screen, or edits.The pattern of general optical pen is more and more many, but the quality of optical pen with otherwise depend on the characteristic of general characteristic and specialty, general characteristic as: weight, hold sense, texture and outward appearance length etc.; The characteristic of specialty is as: written tensile test, life test, electromagnetic interference (EMI), data encryption standards (EDS) test, and the engaged test of written contact panel or the like.In order to reach above-described characteristic, present optical pen is main flow with the metal pen body in conjunction with the plastics nib mostly, has so had texture and attractive in appearance concurrently.Yet how metal pen body and plastics nib firmly link together, and can take into account the emphasis that above-mentioned characteristic but is a necessary research again.

As shown in Figure 1, present existing optical pen structure includes a body A and a written B substantially, and wherein body A one end is provided with the recess A1 of a circle, and the end of written B then is provided with roofbolt B1 that should recess A1; During combination, with all being coated with adhesive agent in roofbolt B1 and the recess A1, then roofbolt B1 is filled in the recess A1, it is fixing to treat that adhesive agent is done back acquisition combination.

A traditional optical shown in Figure 1 structure, its shortcoming is in the manufacturing process, adhesive agent is smeared and is overflowed easily when too much and stick on one's body the pen, and the dried solid time of this adhesive agent is very of short duration, therefore when operation personnel carelessness or wiping totally the time, just be easy to leave a trace on one's body, and be not easy to remove at pen.

Another problem of a described traditional optical structure, be that nib and the assembling of body finish and comprise 45 jiaos of pressure tests, 90 jiaos of pressure tests, and during a series of pressure test of the tensile test etc. of nib, usually cause the bad of joint and fracture, cause the qualification rate of product to reduce because the stress of vertical angle too concentrates.

Summary of the invention

First problem to be solved in the utility model, be that the nib of traditional optical pen is when adopting an adhesive agent to combine with body, cause adhesive agent to overflow easily and be infected with a body, operating personnel's carelessness or the untimely meeting of wiping are left a trace at a body, and then form the shortcoming that fraction defective rises.

Second problem to be solved in the utility model is the nib of traditional optical pen when adopting an adhesive agent to combine with body, and the operating personnel leaves a trace at a body in order to avoid adhesive agent, and the trouble that must adopt various preventive measure in manufacturing process is with inconvenient.

The 3rd problem to be solved in the utility model, be when carrying out a series of pressure test after nib and the assembling of body of traditional optical pen, because too concentrating, the stress of nib causes the bad of joint and fracture easily, so that the shortcoming that the qualification rate of product reduces.

In order to overcome the shortcoming of aforementioned conventional optical pen, first technical scheme provided by the utility model, it is an end that directly nib is embedded in a body, and do not adopt adhesive agent as fixing interface, so can avoid adhesive agent to overflow and be infected with a body, allow the qualification rate of product obtain to improve.

Second technical scheme provided by the utility model, be adopt spheroid form nib directly build-in make more withstand voltage, the anti-distortion of nib, longer service life in the concave arc sphere of a body one end.

Based on this, optical pen structure provided by the utility model, include a body and a nib, the end setting of Yu Bishen is the socket part of concave arc sphere, again a nib that is spheroid is combined in the described socket part, and the outstanding socket part of the some that makes nib, the periphery of this socket part is fixed this nib through exerting pressure distortion, thereby makes nib not need to use adhesive agent with combining of a body.

Compare with prior art, first advantage of the present utility model, be that nib does not need to use adhesive agent that both are combined with a body, therefore do not need worry can take place that adhesive agent is infected with a body and the problem that causes defective products, operator is also more or less freely when assembling, time saving and energy saving, manufacturing cost is minimized.

Second advantage of the present utility model is to utilize the nib of spheroid form to be embedded in the concave arc sphere socket part of a body, so that more withstand voltage, the anti-distortion of nib, longer service life.

Embodiment

Below in conjunction with accompanying drawing the utility model is done more detailed description, so that the utility model is had further understanding.

See also shown in Figure 2ly, technical characterictic of the present utility model is to include a body 1 and a nib 2; A body 1 one ends wherein are provided with a socket part 11, the inside surface of this socket part 11 is the concave arc spherical shape, and form an opening 10 in socket part 11, the diameter W of this opening 10 can be equal to or greater than the diameter D at the center of this socket part 11, and the central point of socket part 11 must be lower than below the position of opening 10.In order to make optical pen possess texture, this body 1 can adopt the metal material manufacturing.

Described written 2 can adopt plastic material to make spheroid form, and the diameter of this nib 2 is made as the diameter D of corresponding described socket part 11.

In the utility model during with 1 combination of nib 2 and a body, nib 2 directly is positioned in the socket part 11, make the part of nib 2 give prominence to socket part 11, with processing equipment exerted pressure and be out of shape (as shown in Figure 3) towards the direction of nib 2 in the edge 12 of socket part 11 then, thereby with the reduced of opening 10 to diameter, so that can make written 2 build-ins in socket part 11 and can not drop out less than nib 2.

According to described design of the present utility model, because nib does not need to use adhesive agent with the combination of a body, therefore do not have the problem that adhesive agent is infected with a body, the assembling operation personnel are also comparatively time saving and energy saving in manufacture process, and by the nib of spheroid and the socket part combination of concave arc sphere, also can improve the withstand voltage and anti-deformation intensity of nib, thereby prolong the serviceable life of product.

The above just is used for explaining preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model in view of the above; therefore; all have any modification relevant of the present utility model or a change of being done under identical creation spirit, all must be included in the utility model protection domain.
