ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a wire winding box, and especially to an alternatively positioned and wound wire winding box for increasing the communicating distance of a wired communication, moreover, the communication cable may be rewound easily and conveniently. By the intermittent pulling and releasing the cable, the cable may be positioned and winding by staged.
BACKGROUND OF THE INVENTION
Various kinds of wire winding boxes are developed for avoiding the improper winding of cables between communication devices, or a wired communication primary machine (for example, the main frame of a telephone) and a communication secondary machine (for example, the receiver of a telephone). The structure of the wire winding box includes a housing, two conductive disks, at least one spiral spring, and two communication cables. One of the conductive disks is installed with a plurality of concentric conductive rings with unequal diameters and connected to each conductive wire of a communication cable. Another conductive disk is installed with a plurality of conductive pieces or metal rolling balls which are connected to the conductive wires of another communication cable. One rotary conductive disk is installed with a spiral spring and is wound by communication cable. Therefore, as two conductive disks are rotates respectively, an electric connection is retained. Thus, the communication cable can be pulled out or rewound. Such kinds of structures have been produced and sold in commercia market.
However, in the prior art wire winding box, the conductive disk can rotate freely and the communication cable is pulled by the elastic force from a spiral spring. Thus, although the communication cable can be pulled successfully, it can not be positioned. Besides, in the conventional wire winding box, as a communication cable is pulled out, it will present a tightening state due to the effect of elasticity so as to rewind the cable and thus the receiver will be pulled back. This is a great trouble to the user.
Therefore, some wire winding boxes have been invented for positioning the communication cable as it is pulled out. In those structure, a swing-able buckling piece is installed at one side within the housing, while the periphery of a rotatable conductive disk is installed with a larger cambered notch and at least one smaller inclined groove. In normal condition, the communication cable can be pulled out freely so as to rotate the conductive disk successfully. While as the communication cable is released so as to wind the communication cable, only the buckling piece is buckled at any inclined groove, then the conductive disk can be caught and positioned. However, if the buckling piece is dropped into a cambered notch, the conductive disk will not be caught again and thus the communication cable can be rewound freely. Thus, the defects in the conventional wire winding box can be overcome effectively and rapidly. But in these wire winding boxes, the position and length of a pulled communication cable can not be precisely controlled and predicted, therefore. often a reversing reaction is generated as a users operates the communication cable. This is a disadvantage in the prior art.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an alternatively positioned and wound wire winding box comprises a housing, a first communication cable, a first conductive disk, a first communication cable, a spiral spring, a second communication cable, a second conductive disk. A swing piece and a ratchet which are adjacent to and overlapped with one another are installed at one side of the one housing. A plurality of grooves are installed around the periphery of the first conductive disk. Each of two sides of the pivotal position of the swinging piece is extended with an integrally formed elastic piece which may resist against the wall of the housing. Another end of the swinging piece with respect to the pivotal position is formed with a tongue which may obliquely resist against the periphery of the disk and at proper condition it can enter into the groove. A plurality of ratchet teeth are installed at the ratchet every other ratchet tooth. The side of the tooth adjacent to the swing piece being installed with a buckling block. At two sides of the bottom of the swing piece adjacent to the ratchet, each is installed with a catch. As the swing piece swings, the ratchet teeth are pushed to engage with a gap between teeth. One of the catches is installed with an engaging block at the lateral side thereof for engaging a respective buckling block. Thus, positioning and rewinding actions of The alternative positioned and wound wire winding box by regularly pulling and releasing the communication cable will make the user clearly understand the relation of the positioning the rewinding of the cable, and thus may control the wire winding box easily and conveniently.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
