Description

Multifunctional mobile phone case

Technical field

The utility model belongs to daily necessities field.

Background technology

Mobile phone it is universal, function is also stronger and stronger, due to listening to music, the functions such as story it is integrated, more increase The functionality of mobile phone also brings enjoyment for daily life, but in order to listen to conveniently, longer earphone can generally be arranged Line, can arbitrarily adjust in this way ear between mobile phone at a distance from.However the length of earphone cable may need to adjust at any time with needs It is whole, when line length is in short demand, it just will produce stacking, easily scraping collision, it is easy to break the danger such as earphone cable.

Invention content

The purpose of this utility model be to provide it is a kind of earphone cable is integrated in mobile phone shell, and can be arbitrary by earphone cable It stretches, and not will produce the Multifunctional mobile phone case for stacking phenomenon.

The utility model is equipped with bobbin winoler on mobile phone shell bottom plate by axle center of spool, and bobbin winoler inside is fluted, Wiring duct box is installed in groove, wiring duct box one end is withstood on groove inner wall, and the other end is withstood on plane scroll spring outer end, Be fixed on spool on the inside of plane scroll spring, earphone cord from being wound on bobbin winoler, earphone thread end from block and position-arresting device it Between pass through, position-arresting device is bow-shaped shrapnel, and one end is fixed on position-arresting device axis, and the other end is equipped with wire bushing, wire bushing set On earphone cable, stop bit piece is installed on position-arresting device axis, stop bit piece front end rides on earphone cable, and spring one end withstands on stop bit piece On, the other end is withstood on spring base, and spring base is fixed on mobile phone shell bottom plate, and extended tabletting is installed on block, The prolongation of tabletting covers on the upside of earphone cable；There is binding post inside wiring duct box；Have on mobile phone shell bottom plate below bobbin winoler Loop wire, loop wire is corresponding with binding post bottom end, and binding post contact is equipped on loop wire, and binding post contact is logical at the mobile phone shell bottom plate back side It crosses conducting wire to connect by conducting wire with headset plug terminal contacts, headset plug end is connected on headset plug terminal contacts.

The utility model is simple in structure, easy to use, due to by earphone cord from being wound on fixed bobbin winoler, so, i.e., Make the very long winding that also can be well-behaved of earphone cable, not will produce and the hazardous acts such as scrape, hang, effectively avoid causing because of earphone line process Danger.

Specific implementation mode

The utility model is that axle center is equipped with bobbin winoler 10 with spool 17 on mobile phone shell bottom plate 18, and bobbin winoler 10 can be with Spool 17 pivots about, and 10 inside fluted 11 of bobbin winoler is installed with wiring duct box 13, wiring duct box in groove 11 13 one end are withstood on 11 inner wall of groove, and the other end is withstood on 12 outer end of plane scroll spring, and the setting of groove 11 is for convenience The installation site of plane scroll spring 12 and wiring duct box 13 is reserved, and 12 one end of plane scroll spring is fixed on spool 17, separately One end is fixed on wiring duct box 13, and the spring works principle of the connection structure of plane scroll spring in tape measure center is identical, plane 12 inside of scroll spring is fixed on spool 17, and earphone cable 1 is wrapped on bobbin winoler 10.1 end of earphone cable is from block 9 and stop bit It is passed through between device 6, position-arresting device 6 is bow-shaped shrapnel, and one end is fixed on position-arresting device axis 8, and position-arresting device 6 can be with position-arresting device axis 8 arbitrarily swing for axle center, and the other end is equipped with wire bushing 7, and wire bushing 7 is sleeved on earphone cable 1, is equipped on position-arresting device axis 8 Stop bit piece 3,3 front end of stop bit piece ride on earphone cable 1, and stop bit piece 3 is transported with position-arresting device axis 8 for axle center as position-arresting device arch is synchronized Dynamic, stop bit piece 3 blocks earphone cable when needed, and earphone cable is detached from when not needing, and earphone cable is made arbitrarily to elongate, will not backspace.Bullet 5 one end of spring is withstood on stop bit piece 3, and the other end is withstood on spring base 4, and spring is for heading on what position-arresting device arcuate tab was classified as.Spring Seat 4 is fixed on mobile phone shell bottom plate 18, and extended tabletting 2, the prolongation Gai Er of tabletting 2 are installed on block 9 1 upside of machine line；The setting of tabletting 2 is exactly that earphone cable is prevented to be detached between block 9 and position-arresting device and set.Have inside wiring duct box 13 Binding post 14；There is loop wire 19 on mobile phone shell bottom plate 18 below bobbin winoler 10, loop wire 19 is corresponding with 14 bottom end of binding post, wiring 14 bottom end of column is contacted across bobbin winoler 10 with loop wire, binding post contact 20 is equipped on loop wire 19, binding post contact 20 is in mobile phone 18 back side of shell bottom plate is connect with headset plug terminal contacts 16 by conducting wire by conducting wire, and headset plug end 15 is connected to headset plug On terminal contacts 16.

The preceding termination of earphone cable is earphone, and the connection of headset plug end is headset plug.In use, first by earphone cable tail End is connected on the binding post of wiring duct box, when needing to elongate, drops earphone cable, in this way due to the effect of wire bushing, is driven The arch of position-arresting device moves out, while stop bit piece being driven to rotate, and is detached from the contact with earphone cable, but plane scroll spring exists It is tightened under the action of bobbin winoler, when being pulled to required length, unclamps earphone cable, inwardly moved in position-arresting device arch, while driving and stopping Bit slice blocks earphone cable, can be blocked by stop bit piece if the power of tightening even if plane scroll spring has, earphone cable will not be made to withdraw. Mobile phone is placed in mobile phone shell, then the plug at headset plug end is inserted in the receiver hole of mobile phone, will be made at this time whole A earphone cable conducting, and connect on a cellular telephone.

It when needing to withdraw earphone cable, as long as gently pulling earphone cable, and is drawn to outside, stop bit piece is detached from this time Earphone cable, then slowly light earphone cable slowly withdraw earphone cable, i.e., at this time under the action of plane scroll spring screen resilience Earphone cable is completed to withdraw.
