Description

An earphone wire take-up device and an earphone using the wire take-up device

technical field

The invention relates to the technical field of communication equipment, in particular to an earphone cable retractor and an earphone using the cable retractor.

Background technique

At present, the earphones commonly used by people all use longer earphone wires to connect the sound source to the earphones. The disadvantage is that when the earphones are not used, the longer earphone wires are piled up and entangled with each other. The entangled earphone wires are sorted out. For this reason, people have designed and produced earphones with a take-up box, so that when the earphones are not in use, the earphone wires can be put into the take-up box, which solves the problem of long earphones when the earphones are not in use. The problem of wires being piled up and entangled with each other, taking Chinese patent ZL200620060847.X as an example, this patent discloses a cable take-up box for earphones, as shown in Figure 1, includes a base 10, a top cover 11, and a set of limited disks 13 The column 12 of the spring 14 is fixed between the base 10 and the top cover 11, and the other end is fixed on the limit plate 13. The limit plate 13 is provided with at least two clamping notches 15, and the bottom of the limit plate 13 is provided with multiple There are three annular grooves, and there is a connecting portion between the annular grooves; a rectangular groove is provided on the inner side of the top cover 11; marbles are sandwiched in the rectangular groove; the opening direction of the rectangular groove is parallel to the diameter of the annular groove. The marble moves between the annular groove and the rectangular groove. When it moves to the connecting part, the marble is stuck, and the limit plate 13 is rotated again to make the marble move into the adjacent annular groove. The marble always moves along the rectangular groove. The groove reciprocates; this kind of earphone with a wire take-up box also has obvious shortcomings. When in use, the length of the outgoing line can only be controlled according to the diameter of the annular groove, and the length of the earphone line cannot be adjusted to any appropriate length according to the needs. The earphone cable needs to be pulled out forcibly and then loosened to reset the spring 14, which will easily cause the earphone cable to be deformed or even broken, which will affect the service life of the earphone cable. Other headphone cable winding tools such as fishbone winders and buckle winders are cumbersome to operate, and the length of the wire cannot be flexibly adjusted during use, causing inconvenience in use.

Contents of the invention

The technical problem to be solved by the present invention is to provide an earphone cable retractor that can be flexibly retracted and the cable length can be flexibly adjusted according to the needs of use, and an earphone using the cable retractor.

In order to solve the above problems, the present invention provides an earphone cable take-up device, which includes a disc-shaped upper cover, a disc-shaped lower cover, a spring seat, and a scroll spring. The center of the lower cover is provided with a central column ; The spring seat is arranged in a ring shape, and the outer wall of the spring seat, the disc-shaped upper cover (1) and/or the disc-shaped lower cover (7) is coated with Teflon coating, and the upper cover and The left and right ends of the lower cover are provided with semicircular clamping gaps; the earphone wire take-up also includes a stop cover for preventing the spring seat from rotating freely, and the earphone wire take-up also includes a scroll spring cover and a Slide and reset slider, the tail of the slider is provided with a pressing part for pressing the wire; the underside of the scroll spring cover is provided with a chute suitable for sliding the slider; the scroll The center of the spring cover is provided with a central hole suitable for the passage of the central column; the earphone cable take-up also includes a slider gland, and the center of the slider gland is provided with a central hole suitable for the passage of the central column.

During assembly, the upper cover and the lower cover are engaged to form a cavity, and the corresponding clamping gaps form the inlet and outlet ends. The spring seat is arranged in the cavity, and the scroll spring is arranged in the annular spring seat. The head of the coil spring is fixedly connected with the side wall of the spring seat, and the tail of the scroll spring is fixedly connected with the center column of the lower cover; the anti-rotation cover is arranged between the upper cover and the spring seat; the scroll spring cover, slider, slider The block gland is sequentially arranged between the lower edge of the spring seat and the lower cover, and the central column is arranged through the center hole of the slider gland, the slider, and the center hole of the scroll spring cover in turn; The scroll spring cover and the slider gland are fixedly connected with the lower cover.

When in use, the wire enters the cavity from the wire inlet end, coils on the outside of the side wall of the annular spring seat, and passes through the wire outlet end; the pressing part of the slider compresses the wire rod; when the length of the wire rod needs to be adjusted, push the The slider keeps the pressing part of the slider away from the wire, and the wire is pulled out along the outlet end. At this time, the spring seat rotates forward, and the scroll spring deforms; after the wire is pulled out to the required distance, release the slider , the slider resets under the action of the return spring and presses the wire again; when the wire needs to be rewound after use, push the slider and press down the anti-rotation cover at the same time, and the spring seat rotates in the opposite direction under the action of the scroll spring's turning torque , to complete the winding of the wire.

Further, the anti-rotation cover is arranged in the shape of a top hat, and a plurality of L-shaped anti-rotation cover buckles are arranged obliquely on the lower edge of the anti-rotation cover; one end of the L-shaped anti-rotation cover buckle is vertically connected with the anti-rotation cover to form a vertical end , the other end is arranged obliquely to form an inclined end; a block is provided inside the annular spring seat, and a plurality of elastic retaining pieces are arranged on the inner side of the top of the spring seat, and there is a space between each adjacent elastic retaining piece that is suitable for the rotation stop The channel through which the cover snaps through, and a spring seat chute suitable for accommodating the lower edge of the anti-rotation cover is formed between the elastic block and the stopper in the spring seat. When the spring seat rotates forward, the L-shaped stop The inclined end of the turn cover buckle lifts the elastic retainer so that the elastic retainer passes through the L-shaped stop cover buckle smoothly, and the spring seat realizes the rotation; at the same time, the vertical end of the L-shaped stop cover buckle forms a block for the elastic stop , so that the spring seat cannot be reversely rotated; the inner side of the hat-shaped anti-rotation cover and the stopper are provided with an anti-rotation cover spring, and the center of the upper cover is provided with a through hole.
