Abstract

The utility model discloses a hank box for a handset earphone, which comprises a spool (1), a discoid left retaining wall (2) and a discoid right retaining wall (3) which are respectively arranged on two ends of the spool (1) and vertical to the axial line of the spool (1), and a pair of top protection walls (4) extended inwards horizontally from the tops of the left retaining wall (2) and the right retaining wall (3). The edges of the two top protection walls (4) are wave edges (5), and a group of circular arc bayonets (6) are formed at the lower part of the wave edges (5). Small gap is formed at the upper part of the wave edge. When a earphone is not be used, the wire of the earphone can be directly put into the spool box, thereby avoiding the winding; so, the hank box is convenient and practical.

Description

Earphone spiral axle casing

Technical field

The utility model relates to Cellphone Accessories, refers to a kind of earphone spiral axle casing that is used on the electronic products such as mobile phone, MP3 especially.

Background technology

Electronics such as most of mobile phones, MP3 all are furnished with earphone, particularly on music phone, and the indispensable especially accessory of earphone.The earphone line is long, twines easily, is rolled into one when not using and is difficult to deposit.

Therefore, be necessary to design a kind of device of earphone line of conveniently placing as Cellphone Accessories.

Summary of the invention

In view of this, the purpose of this utility model provides a kind of earphone spiral axle casing, and this spiral axle casing is rolling earphone line easily, and can carry with mobile phone easily.

The earphone spiral axle casing of the utility model design comprises: roll, be located at these roll two ends respectively and perpendicular to the discoid left side retaining wall and the right side retaining wall of roll axis, and a pair of top retaining wall that inwardly crosses out from left side retaining wall and retaining wall top, right side, this edge to the top retaining wall is set as the ripple limit, ripple limit negative area forms one group of circular arc bayonet socket, and ripple limit bossing forms a slight gap.

The earphone spiral axle casing of the utility model design uses resilient plastic material to make, and the top retaining wall is thin slightly, and stronger elasticity is arranged.During use, the earphone line passes from the gap that left and right top retaining wall forms and is wrapped on the roll, and the two ends of earphone line then are stuck in the adjacent circular bayonet socket.

The utility model is simple in structure, and is easy to use, avoided the earphone line to twine, and elegant in appearance.

Description of drawings

Below in conjunction with accompanying drawing and preferred embodiment the utility model is elaborated, wherein:

Fig. 1 is a front view of the present utility model;

Fig. 2 be among Fig. 1 A-A to cutaway view;

Fig. 3 is the end view of Fig. 1;

Fig. 4 is that earphone and headset plug line are wrapped in the schematic diagram on the earphone spiral axle casing.

Embodiment

As shown in Figure 1 to Figure 3, the earphone spiral axle casing that the utility model is used for mobile phone comprises: roll 1, be located at respectively these roll two ends and perpendicular to the discoid left side retaining wall 2 and the right side retaining wall 3 of roll axis, and a pair of top retaining wall 4 that inwardly crosses out from the top of left side retaining wall 2 and right side retaining wall 3, this edge to the top retaining wall is set as ripple limit 5, produces one group of circular arc bayonet socket 6 separately between 5 negative areas of ripple limit.The diameter of bayonet socket 6 is than the slightly larger in diameter of earphone cord, but less than the size of headset plug 10 and earplug 8 bottoms, its effect is after earphone cord is wrapped on the roll 1, and headset plug 10 and earplug 8 are fixed.Ripple limit 5 bossings form a finedraw type gap, and this gap is slightly less than the diameter or the width of earphone rope.

Operating position of the present utility model as shown in Figure 4, earphone cord spiral axle casing is made of flexible flexible plastic material, its top retaining wall 4 does not hinder the coiling action, though thin gap width is less than the diameter of earphone rope, elastic material can allow its by and be wrapped in smoothly on the roll 1.Coiling is finished (taking up) afterwards, and the final stage earphone cord that connects earplug 8 and headset plug 10 is stuck in the nearest circular bayonet socket 6.

In a preferred embodiment, a lanyard hole 7 (as shown in Figure 4) can be set on the top retaining wall 4, put on this lanyard hole with the mobile phone lanyard, carry with mobile phone.

When earphone does not use, can directly the earphone line be closed in the spiral axle casing, avoid twining, also can separate this moment and deposit with mobile phone, ready access upon use, very convenient.

The utility model is not limited to handset earphone, and the earphone product of other walkman equipment also can use.

Claims (3)

1. earphone spiral axle casing, it is characterized in that comprising: roll (1), be located at respectively these roll two ends and perpendicular to the discoid left side retaining wall (2) and the right side retaining wall (3) of roll axis, and a pair of top retaining wall (4) that inwardly crosses out from the top of left side retaining wall (2) and right side retaining wall (3), this edge to the top retaining wall is set as ripple limit (5), ripple limit negative area forms one group of circular arc bayonet socket (6), and ripple limit bossing forms a gap.

2. earphone spiral axle casing as claimed in claim 1 is characterized in that: make of resilient plastic material.

3. earphone spiral axle casing as claimed in claim 1 is characterized in that: described top retaining wall (4) is provided with span hole (7).
