Abstract

A wire winding box for reducing radial friction, especially a wire winding box for reducing radial friction of a communication wire, is disclosed. A fixing piece is installed in the through hole in the wire winding ring of wire winding disk. The fixing piece serves to clamp and fix the communication wire passing through the through hole so that the communication wire in the wire winding ring can not be pulled. When one end of the communication wire is pulled from the wire winding box, the section of the communication wire in the wire winding ring can not be pulled out. Therefore, as the communication wire is wound back to the wire winding box, the frictions between different sections of the communication wire and between the communication wire and the wire winding ring will not occur. Therefore, the communication wire and the whole wire winding box have a longer lifetime.

Claims

1. A wire winding box for reducing radial friction comprising:

a box body having a wire groove in at least one surface;

each side of the wire groove having a wire hole; and

an inner lateral side of the wire groove having a shaft and a groove hole communicated with an exterior;

a housing for sealing the wire groove;

at least one wire winding disk having a central axial hole at a center of the disk;

an inner surface of the disk having a wire winding ring projecting therefrom to surround a periphery of the center axial hole;

at least one through hole being formed in the wire winding ring;

the wire winding disk being received in the wire groove of the box body in pivotally displaceable manner;

a communication wire coupled to the wire winding disk, the communication wire having first and second segments delineated by an intermediate portion extending therebetween and passing through the through hole of the wire winding ring, the first and second segments of the communication wire being captured by the inner surface of the wire winding disk against the wire groove of the box body;

the first segment of the communication wire being releasably wound externally about the wire winding ring thereof;

the second segment of the communication wire extending from the groove hole and being disposed within an interior of the wire winding ring on the wire winding disk;

the communication wire having a first end passing through the wire hole of the box body and a second end passing through the groove hole of the box body;

at least one spiral spring positioned in the box body and being connected with the wire winding disk; and

,

a fixing piece engaging the through hole in releasably locked manner for clamping and fixing the intermediate portion of the communication wire to the wire winding ring and thereby adjustably delineate the first and second communication wire segments.

2. The wire winding box for reducing radial friction as claimed in claim 1, wherein an inner lateral surface of the wire groove is installed with at least one positioning piece;

a positioning groove is formed between the positioning piece and the shaft;

when the communication wire is inserted from the groove hole, it passes through the positioning groove and is clamped and positioned in the positioning groove.
