Abstract

The utility model relates to a dustproof plug for a headset jack of a mobile phone. The dustproof plug is composed of a body portion which is made of rubber materials and can be inserted into the headset jack, and a gripping portion which is made of rubber materials and retained outside the headset jack, wherein the body portion and the gripping portion have the common axial line. Unlike the prior art, the dustproof plug is provided with a central hole, and a propelling pencil lead, wherein the central hole penetrates the body portion and the gripping portion along the axial line, the diameter of the central hole is 0.4mm, the length of the propelling pencil lead is greater than the sum of the lengths of the body portion and the gripping portion, the diameter of the propelling pencil lead is 0.5mm, and the propelling pencil lead is threaded in the central hole from an opening of the gripping portion and exposed out of the body portion. By adopting the technical scheme, the dustproof plug has the dustproof function and a simple writing function, and has the advantages of being simple in structure and easy to carry.

Description

Handset earphone jack dust plug

Technical field

The utility model relates to a kind of mobile phone dust plug, relates in particular to a kind of with writing function handset earphone dust plug.

Background technology

Along with the development of smart mobile phone, from strength to strength, part has replaced the function of wrist-watch, yellow pages, memorandum to function, and therefore in people's wrist, wrist-watch is fewer and feweri, the paper in pocket, also almost disappearance of pen.But some time mobile phone can not substitute all, although or can replace, but people not can or this function of unskilled grasp, for example, when being sitting on bus, carried out a phone suddenly, need to remember someone's telephone number, ordinary people moment memory capability can be very not strong, if telephone number does not have rule and feature, moment has just been forgotten, the general way of people is that this number is remembered on scraps of paper or directly write in the palm of the hand, but owing to being accustomed to not being with paper with it, pen, paper is also not all right, palm of the hand the back of the hand just, pen is but easy to handle, does the finger of always can not breaking by the teeth go to write? simultaneously, earphone jack on mobile phone may be that interior of mobile phone has been exposed to outer maximum hole, and headset plug is not to be often inserted in jack, the time exposing is far away more than the time of plugging, cause dust to enter interior of mobile phone, especially rainy day, run into and call again, rainwater is easy to from then on flow into interior of mobile phone, cause the illusion of mobile phone water inlet, impact guarantee, even affect the life-span of mobile phone.

Therefore, be necessary to provide a kind of simple in structure, and can provide dustproof, waterproof, simple writing function earphone jack plug.

Summary of the invention

The purpose of this utility model be just to provide this simple in structure, specious, and can provide dustproof, waterproof, simple writing function earphone jack plug.

For achieving the above object, the technical solution of the utility model is: this handset earphone jack dust plug, body 1 and indwelling by quality of rubber materials in can plugged earphone jack form in the grip part 2 of earphone jack outer rubber material, there is common axial line body 1 and grip part 2, along axial line, a centre bore 3 that connects body 1 and grip part 2 is set unlike the prior art, the diameter of centre bore is 0.4mm, also has one section of propelling pencil lead 4 that is more than or equal to body 1 and grip part 2 length sums, its diameter D is 0.5mm, in the opening penetrating into center hole 3 of grip part 2 and expose outside body 1.Adopt this technical scheme, dust reduction capability not only can be provided, simple writing function can also be provided.Simple in structure, easy to carry.

Preferred version is the circumferential setting above anti-skidding flange 5 together of described body 1.Can prevent the landing of dust plug.

Brief description of the drawings

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

Embodiment

With reference now to accompanying drawing, embodiment of the present utility model is described:

As shown in Figure 1, earphone dust plug 1 described in the utility model, body 1 and indwelling by quality of rubber materials in can plugged earphone jack form in the grip part 2 of earphone jack outer rubber material, the anti-skidding flange 5 that 3 roads are circumferentially set of body 1, there is common axial line body 1 and grip part 2, along axial line, a centre bore 3 that connects body 1 and grip part 2 is set, the diameter of centre bore is 0.4mm, body 1 and grip part 2 length sums are 2.5cm, get 0.5 propelling pencil lead 4 that the current student of a length 8cm generally uses, its diameter D is 0.5mm, in the opening penetrating into center hole 3 of grip part 2 and expose 2mm outside body 1, then the propelling pencil lead being exposed to outside grip part 2 is fractureed.Because the diameter of centre bore is slightly less than the diameter of pen core, quality of rubber materials has certain elasticity in addition, and pen core is not easy in can being wrapped in tightly to slide, and is conducive to write.

When exposing in use procedure after pen core outside body 1 is finished, push up inwards from the opening of grip part 2 with toothpick or clip, pen core is exposed outside body 1 again.

After this is finished with pen core, again change a new pen core.

Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
