The wire coiling device can automatically wind the signal wire, and has the advantages of simple structure, low cost, and convenient operation.

Description

Winder

The utility model relates to a kind of winder, particularly a kind of take-up winders such as electronic product signal wire (SW) that are used for.

Existing portable recording playback machine, radio receiver, CD player and cellular telephone machine, all be to be fixed on earphone and microphone on the fuselage or the earphone cord of earphone and microphone or band microphone received on the fuselage to use, the former in use, easily the user is produced acoustic noises, as produce noise or noise and excitement when listening to the radio; Or electromagnetic radiation healthy unfavorable to the user, the strong electromagnetic wave of its generation can cause harmful effect to human body when conversing in one's ear as mobile phone is taken; The latter in use, though avoided above-mentioned shortcoming, after must earlier earphone cord one end being inserted fuselage before earphone uses and finishing using, long earphone cord is not easy to collection again and carries, in addition, often have little time to insert earphone cord etc. when answering the call, use still inconvenient.

In view of this, how can avoid surrounding environment noise jamming and avoid interference around, and avoid the ill effect of electromagnetism to human body, can converse clear again or listen to clear, the puzzlement of avoiding line and plug earphone to bring, and it is simple in structure, therefore can't increase on the cost under many situations, just can bring easy to usely greatly, give the user one and select flexibly, just this novel wound motivation place of grinding.

The utility model designer relies on the experience of life observation for a long time and is engaged in the practical experience that each electronic product is researched and produced processing and other fields for many years, on the basis of feasibility study repeatedly, does a brand-new design and constitutes, and gets this later-model generation eventually.

At the deficiencies in the prior art, this later-model purpose is the winder of a kind of automatic winding signal wire (SW) of design, and he can be used with other electronic products.

The purpose of this utility model can be by following realization: this novel spiral sheave that is provided with in the enclosure, the broadband type string wire is installed in the interlayer wall in the spiral sheave, the two ends of string wire are connected respectively on center shaft and the interlayer wall, the outer winding signal line of interlayer wall, signal wire (SW) one end is welded on the circular conductive plate of spiral sheave outside, conductive plate contacts with the contact of shell, and the contact directly extends on the outside latch by lead again, and the external connection end of signal wire (SW) is placed on the outside of shell.Between shell and spiral sheave, establish a non-return drg.Between shell and spiral sheave, also a pinch roller can be set.

The utility model can be placed in mobile phone, CD player, the recording playback radio receiver because volume is small and exquisite, pulls out when earphone or the microphone signal coil of wire are used in winder, after finishing using, as long as touch by the non-return actuator button, signal wire (SW) can be automatically withdrawn in the winder, and is easy to use.

Further illustrate the utility model below in conjunction with accompanying drawing

Fig. 1 is the utility model cut-away view.

Fig. 2 is the utility model sectional structure chart.

Fig. 3 is used in structural representation in the mobile phone for the utility model.

This novel spiral sheave 3 that in shell 9, is provided with, broadband type string wire 13 is installed in the interlayer wall 6 in spiral sheave 3, the two ends of string wire are connected respectively on center shaft 4 and the interlayer wall 6, interlayer wall 6 outer winding signal lines 12, signal wire (SW) one end is welded on the circular conductive plate 14 of spiral sheave outside, conductive plate contacts with the contact 15 of shell, the contact directly extends on the outside latch 16 by lead again, be connected with matching used main frame, the external connection end 1 of signal wire (SW) is placed on the outside of shell, but external connection end 1 lug machine 18 or microphone 17; During use, earphone is outwards pulled out, spiral sheave 3 is just along with signal wire (SW) rotates, simultaneously with the compression of the string wire in interlayer wall tension, at this moment, compression string wire 13 is subjected to elasticity to produce an outside tension force, and this tension force has makes the signal wire (SW) of pulling out to the effect of pulling back, and can realize the effect of unrolling automatically when not using; For preventing to unroll in use, establish a non-return drg 7 at shell 9 and 3 of spiral sheaves, when spiral sheave 3 during to back rotation, non-return drg 7 can be clipped between shell and the spiral sheave stop the spiral sheave to back rotation when finishing using take-up, pin withdrawal button 11 with hand, the non-return drg is under the effect of drive link 10, leave spiral sheave 3, at this moment the spiral sheave under the effect of string wire to back rotation, automatically signal wire (SW) is regained and is wrapped on the interlayer wall 6 of spiral sheave, relay part is stuck in the seat outside when relay part is got back to external element seat 2 outside as earphone etc., and the spiral sheave stops operating; Because of the non-return drg is an one-way brake,,, should select for use the material of certain tensile strength to do signal wire (SW) in order to prevent that in long-term use signal wire (SW) bears pulling force for a long time so when outwards pulling out signal wire (SW), needn't pin button.Irregular for avoiding signal wire (SW) to twine when unrolling, it is bigger to take up room, and therefore, at shell 9 and 3 of spiral sheaves a pinch roller 5 can be set also, and the compression signal line makes its marshalling.

The application of the utility model on mobile phone, see also Fig. 3, the utility model is installed in the bottom of mobile phone, relay part earphone 18 and microphone 17 outside on signal wire (SW) 12, being connected with, during use, the earphone of pulling out can directly be inserted in the ear, yet microphone can both be very from not being subjected to ambient interference near the mouth listening and speaking, can interference environment yet, and because head can be away from mobile phone, also can avoid the ill-effect of electromagnetism to human body, and owing to use earphone and microphone to hang in one's ear, hand can also be write and note down or operate automobile etc.; The utility model equally also can with supporting uses such as CD player, recording playback radio receiver, the utility model also can be at shell peripheral hardware one hook 19 (referring to Fig. 2), can be separately not at waist, use in the lump after utilizing latch 16 and other electronic products connecting.

This is novel to have simple in structurely, easy to use, supporting when being used for electronic product really, brings the function of a lot of reality and convenient to electronic product.

In sum, basis is novel can utilize simple structure design, and it is upward convenient that supporting novel electronic product used.Obviously originally novel is the new design of a kind of novelty, progress and dark tool practicality.The above is this later-model specific embodiment and the know-why used, the equivalence that the later-model conception of Ruo Yiben is done changes, when the function that it produced does not exceed spiritual that specification sheets and accompanying drawing contain yet, all should be in this later-model scope, explanation hereby.
