Abstract
The utility model discloses a flexible earphone which comprises a flexible wire connected with an earplug and an earphone pin, as well as a shell box that can accommodate the earphone flexible wire. The shell box is internally provided with a control device that can control the flex of the earphone flexible wire that can flex and position randomly to prevent from the exposure, and avoid the fetter to the customer or the passerby; moreover, the earphone flexible wire is not easy to be knotted or pulled, thereby enhancing the service life of the earphone flexible wire.
Description
Technical field
The utility model relates to a kind of earphone, relates in particular to a kind of telescopic earphone.
Background technology
At present, the employed earphone of people mainly contains two kinds, a kind of is wired earphone, a kind of is wireless headset, and wired earphone all needs to connect long earphone flexible cord, and the earphone flexible cord all exposes, and uses the people who is walked about in user or next door and causes yoke, make troubles and perplex, and earphone flexible cord knotting or useful life of being pulled pulling-down cropped ear machine flexible cord easily outside.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of telescopic earphone easy to use is provided.
For achieving the above object, the technical solution of the utility model is: telescopic earphone, comprise the earphone flexible cord that is connected with headset plug with earplug, it also comprises a housing box that can hold described earphone flexible cord, is provided with the flexible control device of the described earphone flexible cord of may command in the described housing box.
As a kind of improvement, described control device comprise be arranged at described housing box inside can be around a pivotally supported rotating disk, described earphone flexible cord coils the outer peripheral face in described rotating disk, it also comprises the clockwork spring that coils in described pivot, described clockwork spring is positioned at the toroidal cavity of described pivot and the formation of described rotating disk, one end of described clockwork spring is fixedlyed connected with described earphone flexible cord, and its other end is fixed in described pivot; Also be provided with the ratchet mechanism of a described dial rotation of control in the described housing box.
As a kind of further improvement, described ratchet mechanism comprises the ratchet that is fixed in rotating disk, can around bearing pin swing and with the suitable sour jujube bar of described ratchet, fixedly connected with described sour jujube bar and stretch out the control button of described housing box outside, it comprises that also is installed on the spring that the described sour jujube bar of making of described bearing pin resets.
As a kind of further improvement, described housing box is made up of the last box and the following box of clamping.
Because adopt technique scheme, telescopic earphone comprises the earphone flexible cord that is connected with headset plug with earplug, it also comprises a housing box that can hold described earphone flexible cord, is provided with the flexible control device of the described earphone flexible cord of may command in the described housing box; The earphone flexible cord can arbitrarily stretch and locate, and the earphone flexible cord is no longer exposed, and use the people who is walked about in user or next door and can not cause yoke again, and the earphone flexible cord has increased the useful life of earphone flexible cord also being difficult for knotting or being pulled and draw.
Description of drawings
Fig. 1 is the generalized section of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, telescopic earphone comprises the earphone flexible cord 2 that is connected with headset plug 3 with earplug 1, and it also comprises a housing box 4 that can hold described earphone flexible cord 2, is provided with the control device that the described earphone flexible cord 2 of may command stretches in the described housing box 4.
Described control device comprise be arranged at described housing box 4 inside can be around a pivotally supported rotating disk 5, described earphone flexible cord 2 coils in the outer peripheral face of described rotating disk 5, it also comprises the clockwork spring 6 that coils in described pivot, described clockwork spring 6 is positioned at the toroidal cavity of described pivot and 5 formation of described rotating disk, one end of described clockwork spring 6 is fixedlyed connected with described earphone flexible cord 2, and its other end is fixed in described pivot; Also be provided with the ratchet mechanism 7 that a described rotating disk 5 of control rotates in the described housing box 4.
Described ratchet mechanism 7 comprises the ratchet 8 that is fixed in rotating disk 5, can around bearing pin swing and with the suitable sour jujube bar 9 of described ratchet 8, fixedly connected with described sour jujube bar 9 and stretch out the control button 10 of described housing box 4 outsides, it comprises that also is installed on the spring 11 that the described sour jujube bar 9 of making of described bearing pin resets.
Described housing box 4 is made up of the last box 12 and the following box 13 of clamping.
The operation principle of present embodiment scheme is as follows:
On the circle wall of rotating disk 5, be shaped on a zigzag ratchet 8, can swing around bearing pin with the sour jujube bar 9 that ratchet 8 matches, spring 11 is enclosed within on the bearing pin, one of spring 11 is pressed on the axle of the button 10 that is connected with sour jujube bar 9, the other end fixes on the pin, bearing pin, pin and last box 12 are one, because the active force of spring 11, make sour jujube bar 9 be crushed on all the time on the ratchet 8, thereby the direction that ratchet 8 can only be drawn out to earphone flexible cord 2 rotates, and can not reverse, when earphone flexible cord 2 is drawn out, just band clockwork spring 6 is tightened, make rotating disk 5 that a rotatory force that the earphone flexible cord is reclaimed be arranged, because ratchet 8 is one with rotating disk 5, ratchet 8 is withstood by sour jujube bar 9, make earphone flexible cord 2 not regain in the box, and have the ability that self-locking is stopped.When earphone flexible cord 2 needs to regain in the box, as long as promote button 10, make the apical tooth on the sour jujube bar 9 leave ratchet 8, at this moment rotating disk 5 just can reverse, and earphone flexible cord 2 just is retracted in the box.
