Abstract

A wire winding box for short distance use is provided that includes a case with single receiving tank or two receiving tanks having a rotary disk rotatably installed therein which is driven by a spiral spring. A communication wire passes through a pivotal shaft for engaging with the rotary disk, then is bent through a proper angle, then is pulled to a ring of the rotary disk, and then is pulled out through the line outlet or is wound. As the rotary disk rotates, the wire will be wound around the ring and around the pivotal shaft to be pulled out or rewound rapidly. Additionally, a swingable piece and a ratchet wheel are partially overlapped and are pivotally installed in the receiving tank adjacent the rotary disk. Accordingly, through the regular action of alternatively pulling and releasing the communication wire can be easily positioned and rewound.

Claims

1. A wire winding box for short distance use, comprising:

a case formed by a first half case, a central seat and a second half case which together form two receiving tanks at two sides of said central seat, said central seat having a pivotal shaft extending therethrough into each of the receiving tanks, said pivotal shaft having a line outlet formed in each of two opposing ends thereof;

a pair of rotary disks respectively rotatably disposed in the two receiving tanks, each rotary disk having a pivot hole formed therein for pivotal engagement on the pivotal shaft to be rotatable thereon, each rotary disk having a first side with a first ring formed adjacent the pivot hole and a second side with a second ring formed adjacent the pivot hole, the first ring being formed with a hooking slot and the second ring having a slot formed therein;

a single communication wire passing through the pivot shaft and extending from each of the line outlets thereof, a portion of the wire extending from each line outlet being bent through a predetermined angle and wound around the pivotal shaft and then being passed through the slot of a corresponding one of the second rings of the two rotary disks; and

,

a pair of spiral springs respectively received in the two receiving tanks adjacent respective rotary disks, each of the spiral springs having a hook end connected to the hooking slot of the first ring of respective rotary disk to provide an elastic rotative restoring force to the respective rotary disk.

2. The wire winding box for short distance use as claimed in claim 1, wherein two ends of the communication wire protrude from two line outlets on one side of the case.

3. The wire winding box for short distance use as claimed in claim 1, wherein two ends of the communication wire protrude from two line outlets on different sides of the case.

4. A wire winding box for short distance use, comprising:

a case having at least one receiving tank with a pivotal shaft therein, each of two opposing ends of the pivotal shaft having a respective line outlet formed therein, said case having a pair of line outlets, one of the line outlets in the case being disposed in alined relationship with a corresponding line outlet at one end of the pivotal shaft;

at least one rotary disk disposed in the receiving tank and having a pivot hole formed therein and rotatably engaged to the pivotal shaft, the rotary disk having a first side with a first ring formed adjacent the pivot hole and a second side with a second ring formed adjacent the pivot hole, the first ring being formed with a hooking slot and the second ring having a slot formed therein, the second ring of the rotary disk being formed by a plurality of rollers arranged in a circular pattern;

at least one communication wire, one end of the communication wire passing through the line outlets of the pivotal shaft to pass through a corresponding line outlet of the case, an opposing end of the wire being bent through a predetermined angle to be wound around the pivotal shaft and then pulled through the slot of the second ring, the wire being wound around the second ring and then protruding out of another of the line outlets of the case; and

,

at least one spiral spring disposed in the receiving tank adjacent the rotary disk, the spiral spring having a hook end connected to the hooking slot of the first ring to provide an elastic rotative restoring force to the rotary disk.

5. A wire winding box for short distance use, comprising:

a case having at least one receiving tank with a pivotal shaft therein, each of two opposing ends of the pivotal shaft having a respective line outlet formed therein, said case having a pair of line outlets, one of the line outlets in the case being disposed in alined relationship with a corresponding line outlet at one end of the pivotal shaft;

at least one rotary disk disposed in the receiving tank and having a pivot hole formed therein and rotatably engaged to the pivotal shaft, the rotary disk having a first side with a first ring formed adjacent the pivot hole and a second side with a second ring formed adjacent the pivot hole, the first ring being formed with a hooking slot and the second ring having a slot formed therein, the rotary disk having a plurality of buckling grooves formed in a periphery thereof;

a swingable piece and a ratchet wheel being partially overlapped and pivotally installed in the receiving tank adjacent the rotary disk, the swingable piece having a pair of angularly extending elastic pieces for resisting against a wall of the case respectively installed on two sides of the pivotal connection of the swingable piece, the swingable piece having a tongue formed thereon for obliquely resisting against the periphery of the rotary disk or insertion into the buckling groove, the ratchet wheel being formed with a plurality of ratchet teeth, every other one of the ratchet teeth being formed with a buckling block, the swingable piece having a catch respectively formed at each of two sides thereof adjacent to a bottom of the ratchet wheel, the swingable piece having an engaging block formed adjacent each respective catch, wherein as the swingable piece is swung, a ratchet tooth can be pushed and then engaged into a proper gap, and a respective engaging block is engaged with a respective buckling block;

at least one communication wire, one end of the communication wire passing through the line outlets of the pivotal shaft to pass through a corresponding line outlet of the case, an opposing end of the wire being bent through a predetermined angle to be wound around the pivotal shaft and then pulled through the slot of the second ring, the wire being wound around the second ring and then protruding out of another of the line outlets of the case; and

,

at least one spiral spring disposed in the receiving tank adjacent the rotary disk, the spiral spring having a hook end connected to the hooking slot of the first ring to provide an elastic rotative restoring force to the rotary disk.
