The worm screw engages with turbine, and the left end of the shaft is equipped with handwheel.
Preferably, the shell is rectangular configuration, and the rear side of the shell is equipped with hook.
Preferably, the installed in front of the shell has web plate, and the inside of the shell is equipped with loudspeaker, the position of the loudspeaker
It sets opposite with web plate.
Preferably, the upside of the winding box is equipped with strip hole, and the earphone cable is passed through from strip hole.
Preferably, the inner end of the hollow shaft is equipped with rotary joint, and the other end and rotary joint of the earphone cable connect
It connects.
Preferably, the worm screw is circular tube shaped and is socketed in shaft that the inner cavity top of the winding box is fixedly connected with
Baffle, the baffle are located at the rear side of worm screw.
Compared with prior art, the utility model has the beneficial effects that the earphone cable extension elongation of the utility model can be into
Row is adjusted, and specific regulating step is, drives worm screw rotation by rotation handwheel, and worm screw drives turbine to rotate again, around wheel carry out around
Line or unwrapping wire, to adjust the extension elongation of earphone cable.Earphone cable is adjusted to suitable extension elongation, earphone cable can be greatly reduced
Winding is beaten the case where connecing, and is easy to use.
Detailed description of the invention
Fig. 1 is the utility model side structure schematic view；
Fig. 2 is the utility model forward sight structural schematic diagram；
Fig. 3 is partial enlarged view at A in the utility model Fig. 1.
In figure: 1, shell；2, it links up with；3, earphone cable；4, headset；5, web plate；6, winding box；7, handwheel；8, hollow shaft；9,

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of guide interpreting instrument preventing earphone cord from being wound
Structure, including shell 1, earphone cable 3 and headset 4, the front side of the shell 1 is fixed to understand the winding box 6 for having rectangle, the receipts
Volume box 6 is rotatably connected to perforative hollow shaft 8, and one end of earphone cable 3 is passed through from hollow shaft 8 is connected to rotary joint 14, described
It is equipped in hollow shaft 8 around wheel 9, the earphone cable 3 is wrapped on wheel 9, and one end of the earphone cable 3 is connect with headset 4, institute
The inner end for stating hollow shaft 8 is run through the side wall of shell 1 and is rotatablely connected with it, and turbine 10, the receipts are equipped in the hollow shaft 8
Volume box 6 is rotatably connected to the perforative shaft 15 in left and right, and worm screw 11, the worm screw 11 and whirlpool are fixedly connected in the shaft 15
10 engagement of wheel, worm screw 11 and turbine 10 are plastic material, and the left end of the shaft 15 is equipped with handwheel 7.
Specifically, the shell 1 is rectangular configuration, the rear side of the shell 1 is equipped with hook 2, and hook 2 is for explaining this
Instrument is hung on waistband.
Specifically, the installed in front of the shell 1 has web plate 5, the inside of the shell 1 is equipped with loudspeaker, the loudspeaker
Position and web plate 5 it is opposite, loudspeaker amplify outward through web plate 5.
Specifically, the upside of the winding box 6 is equipped with strip hole 12, the earphone cable 3 is passed through from strip hole 12.
Specifically, the inner end of the hollow shaft 8 is equipped with rotary joint 14, the other end of the earphone cable 3 connects with rotation
First 14 connection, rotary joint 14 use MOFLON/MV model electricity rotary joint, so that when rotation carries out coiling around wheel 9, earphone
Line 3 remains up, and the other end of rotary joint 14 is connect with internal loudspeaker.
