Abstract
A device for preventing an earphone cord from knotting is characterized by including an upper housing, a lower housing, a rotation shaft, a cord clamping groove, earphone cord grooves, an immobilizing device clamping groove, an immobilizing device switch and an immobilizing device. The rotation shaft is positioned in the lower housing. The immobilizing device clamping groove is positioned at one end of the rotation shaft while the cord clamping groove is positioned at the other end of the rotation shaft. The immobilizing device is positioned in the lower housing and is connected with the immobilizing device switch outside the lower housing. The earphone cord grooves are disposed in the lower housing and/or the upper housing. A rotation shaft handle is positioned outside the lower housing. The device for preventing the earphone cord from knotting is simple in structure and convenient to operate. The length of the earphone cord can be adjusted conveniently, and the earphone cord is prevented from knotting.
Description
Technical field
The utility model relates to a kind of small household appliances machinery, relates in particular to a kind of device that prevents earphone cord knotting.
Background technology
In the time that earphone does not use, carefully earphone cord is twined in any case, also usually can make earphone cord knotting.Therefore, in the time that needs use earphone, just can waste the plenty of time and untie the knot of earphone cord, can cause earphone broken line body simultaneously.
Summary of the invention
In order to overcome the easily deficiency of knotting of existing earphone cord, the utility model provides a kind of device that prevents earphone cord knotting, and this device can not only be avoided earphone cord knotting, and can regulate easily the length of earphone cord.
The utility model solves the technical scheme that its technical problem adopts:
Prevent the device of earphone cord knotting, it is characterized in that, this device comprises upper shell, lower house, rotating shaft, cable clamping interface, earphone wire casing, static device draw-in groove, static device switch, static device, rotating shaft is positioned at lower house, static device draw-in groove is positioned at one end of rotating shaft, and cable clamping interface is positioned at the other end of rotating shaft, and static device is positioned at lower house and is connected with the static device switch of lower house outside, earphone wire casing is on lower house and/or upper shell, and rotating shaft handle is positioned at outside lower house.
Wherein upper shell is that buckle is connected or magnetic connects with lower house.
Its shaft is spring rotary shaft.
Wherein static device draw-in groove is one week continuous or be interrupted groove in rotating shaft.
Wherein static device is with projection.
The beneficial effects of the utility model are that simple in structure, convenient operation, can regulate easily earphone length and can prevent earphone cord knotting.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Figure 1 shows that lower house; Figure 2 shows that upper shell.
1. lower houses in figure, 2. upper shell, 3. rotating shaft, 4. cable clamping interface, 5. earphone wire casing, 6. static device draw-in groove, 7. static device switch, 8. static device.
Embodiment
Figure 1 shows that lower house, Figure 2 shows that upper shell, wherein upper shell 2 and lower house 1 can be opened or merge and be combined into a housing, rotating shaft 3 is for being arranged on the rotating axle on lower house 1, be provided with the static device draw-in groove 6 matching with static device 8 in one end of rotating shaft 3, static device 8 is positioned at lower house 1 and is fixedly connected with the static device switch 7 of lower house 1 outside, on lower house 1 and/or upper shell 2, be provided with the earphone wire casing 5 of placing for earphone cord, on the other end of rotating shaft 3, be provided with the cable clamping interface 4 for blocking earphone cord, be outside equipped with the rotating shaft handle (not shown) of rotatable rotating shaft 3 at lower house 1.
The device that wherein upper shell 2 and lower house 1 can be convenient to combine, dismantle by magnet arrangement, bayonet unit etc. is combined.
Its shaft 3 is spring rotary shaft, and it relies on the elastic force homing of spring.
Wherein static device 8 is with projection, and projection can be inserted and in static device draw-in groove 7, prevent that rotating shaft 3 from rotating.Draw-in groove 7 is for being arranged on continuous groove of rotating shaft 3 one weeks or multiple grooves of space.
The using method of device that prevents earphone cord knotting is as follows: separately upper shell 2 and lower house 1, by earphone wire sleeve on cable clamping interface 4, by earphone cord from being wound in rotating shaft 3, after winding, earphone cord is placed in earphone wire casing 5, then upper shell 2 and lower house 1 are combined to composition housing, need to use earphone time, earphone and plug are pulled out to the direction away from housing, while moving Len req to, stir static device switch 7, static device 8 is along with static device switch 7 moves and is stuck on static device draw-in groove 6, make rotating shaft 3 not rotatable, earphone cord stretches out the length of housing to be fixed.After earphone is finished using, stir static device switch 7, static device 8 is separated with static device draw-in groove 6, rotating shaft 3 is rotated under the effect of spring force or rotating shaft handle, drives earphone cord to rotate, and earphone and plug contract to housing.
