Description

A kind of earphone line case

Technical field

The utility model relates to a kind of earphone line case, a kind of specifically box body that can free telescopic earphone line.

Technical background

Earphone cord is a kind of flexible cord, and is supporting with mobile phone, walkman, MP3, broadcast receiver etc., is widely used in life, but people also are the length worries of earphone cord, and earphone cord is too short then to use inconvenience, long then tangled up and knotted easily.

In order to solve the problem of earphone cord, people have expected using a kind of box body to be used for depositing earphone cord, a fixed rotating shaft is arranged in the box body, earphone cord is wrapped in the rotating shaft, connect earphone and device by the outer hole on the box body again, people are free to pull out the earphone cord in the rotating shaft, also can be by the outer knob on the box body that is connected and fixed rotating shaft again with on the earphone cord wraparound fixed rotating shaft, and this method can effectively be put the mobile phone line in order, make it be difficult for knotting, but,, waste time and energy owing to all adopt manually, simultaneously, do not have control device during backguy, be not easy to control the length of wanting the line of pulling out, once line is pulled out easily yet.

Summary of the invention

Goal of the invention of the present utility model is in order to solve the problems of the technologies described above, to provide a kind of simple in structure, convenient and practical, time saving and energy saving, can arbitrarily controlling the technical scheme of the length of pulling out line.

The utility model is achieved through the following technical solutions, and is provided with fixed rotating shaft and the earphone cord that is wrapped on the fixed rotating shaft in the box body, and earphone cord is drawn by the outer hole of box body and connected earphone or other device; Be provided with clockwork spring between described fixed rotating shaft and the box body, set-up mode has multiple, and purpose is can drive clockwork spring by fixed rotating shaft.Perforation can be set on fixed rotating shaft, answer with the gear mesh on the clockwork spring, clockwork spring is looped around on the fixed rotating shaft, with the whole interlocks of the perforation on the fixed rotating shaft; Also can place a side of fixed rotating shaft, with the perforation part interlock on the fixed rotating shaft.

Be provided with upper moveable rod in the described fixed rotating shaft, its top is connected by axle with box body button outward, and the bottom is provided with spring; Push rod is connected the other end of fixed rotating shaft, and is corresponding with spring, is used for extrusion spring; Upper moveable rod is provided with the annular unidirectional stops that supports that shell fragment passes on hole and the lid on the described fixed rotating shaft and cooperates, and promptly shell fragment can be along the unidirectional rotation of supporting a direction of work on the stops; The size in the hole in the rotating shaft moves down by upper moveable rod drive shell fragment after being set to press button, can make shell fragment flick unidirectional purpose of supporting stops to reach; The described unidirectional stops that supports can be designed as annular ratchet.

Described shell fragment can be for one or more.When earphone cord was pulled out and taken in by the box body hole, bigger with the edge friction in hole, invention was provided with fixed pulley on the box body hole, can reduce the friction of earphone cord, increases useful life.Fixed pulley can be installed one, also can install two, promptly up and down or about corresponding the installation.

Fig. 2 is the utility model cutaway view of clockwork spring and the interlock of fixed rotating shaft part.

Embodiment

With reference to the accompanying drawings the present invention is further explained explanation.

Button 1 is connected with two shell fragments 4 and cooperates with annular ratchet 3 by the hole on the fixed rotating shaft 10 by axis 2 be linked in sequence upper moveable rod 5, spring 11 in the fixed rotating shaft 9 in the utility model accompanying drawing 1 on the upper moveable rod 5; Be provided with clockwork spring 6 in the box body 1, be looped around on the fixed rotating shaft 9, perforation 7 interlocks on its gear parts and the fixed rotating shaft 9, push rod 13 is used for extrusion spring 11, makes the shell fragment 4 on the upper moveable rod 5 keep pressing annular ratchet 3.Earphone cord 8 is on fixed rotating shaft.

When the outside timesharing of the box body that elongates earphone cord 8, the earphone cord 8 in the box body is because the external force effect drives fixed rotating shaft 9 rotates to a direction, and the fixed rotating shaft 9 of rotation is strained clockwork spring 6 on the one hand, drives shell fragment 4 on the other hand and slides along forward at annular ratchet 3; When moving suitable length to, when no longer spurring mobile phone line 8, the clockwork spring 6 of tension drives fixed rotating shaft 9 backward rotation, but the shell fragment on the fixed rotating shaft 94 is owing to can only slide towards forward along annular ratchet 3 pressing of spring 11, when its during to reverse slide, then propped up by annular ratchet 3, at this moment, the earphone cord of pulling out also no longer reclaims.

When needs reclaim earphone cord 8, only need press the button 1, by upper moveable rod 5 downward extrusion springs, upper moveable rod 5 is moved down, shell fragment 4 also moves down, and flicks annular ratchet 3, and then La Jin clockwork spring 6 does not have behind the resistance to counter-rotation, drive fixed rotating shaft 9 to backward rotation, and earphone cord 8 is rewound on the fixed rotating shaft 9; After receiving suitable length, unclamp the button of pinning 1 then, spring withstands upper moveable rod 5 once more, also makes shell fragment 4 press annular ratchet 3, can not be to backward rotation, and fixed rotating shaft is stuck once more, and the action of exhausting line is stopped.

Earphone cord 8 stretches out from the hole on the box body, and the hole is provided with two corresponding fixed pulleys 12, and reeling of earphone cord 8 can be slided on fixed pulley 12, reduces the friction when reeling earphone cord 8.

Accompanying drawing 2 is that clockwork spring 6 no longer is that ring is on fixed rotating shaft 9 with the difference of accompanying drawing 1, clockwork spring 6 can be placed a side of fixed rotating shaft 9, perforation 7 part interlocks on gear on it and the fixed rotating shaft 9: fixed rotating shaft 9 rotates during backguy, drives the tension of clockwork spring 6 by perforation 7.Under the active force of clockwork spring 6, drive the rotation of fixed rotating shaft 9 during take-up, can reach the function of convergent-divergent earphone cord equally.

The utility model is simple in structure, be skillfully constructed, earphone cord can be carefully and neatly done receive in the earphone line case, the situation of tangled up and knotted can not appear again, by clockwork spring with unidirectional support stops cooperate, earphone cord is freely stretched to suitable length and fixing, need not motor, energy savings, time saving and energy saving, easy to use, can extensively popularize use.And the method not only can be used for also can be used for the consolidation of all flexible cords in the arrangement of earphone cord.

In like manner, the utility model can also other conventional connected mode reach function of the present utility model, and the modification of any common-sense all belongs to protection range of the present utility model.
