ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a wire winding box for reducing radial friction, and especially to a wire winding box for reducing radial friction against a communication wire.
BACKGROUND OF THE INVENTION
The current communication devices, such as computers, modems, telephones, or fax machines, need communication wires to connect these devices for communication. However, in order to keep a communication wire from being too long to be wound or too short for effective use, there are various wire winding boxes being designed.
Referring to
FIG. 1
, a prior art wire winding box includes a box body
1
a
, a housing
2
a
, a communication wire
3
a
, two wire winding discs
4
a
and two spiral springs
5
a
. The box body
1
a
has two faces each being installed with a wire groove
11
a
for receiving the communication wire
3
a
. Each lateral side of the wire grooves
11
a
is installed with a wire hole
12
a
at an appropriate place for passing the two ends of the communication wire
3
a
therethrough. The inner lateral side of the wire groove
11
a
is formed with a shaft
13
a
. Each shaft
13
a
is axially installed with a groove hole
14
a.
The housing
2
a
is formed by a first casing
21
a and a second casing
22
a
, which can be buckled to the two surfaces of the box body
1
a
for sealing the two wire grooves
11
a
so as to position the communication wire
3
a
, wire winding disk
4
a
, and spiral spring
5
a
in the box body
1
a.
Two wire winding disks
4
a
has a central axial hole for
42
a
. Two surfaces of the disk
41
a
are formed with a spring fixing post
43
a
and a wire winding ring
44
a
. The spring fixing post
43
a
and the wire winding ring
44
a
surround the periphery of the central axial hole
42
a
and are concentric with the central axial hole
42
a
. The spring fixing post
43
a
is installed with a buckling hole
45
a
. The two wire winding disks
4
a
are received in the two wire grooves
11
a
in the box body
1
a
and are pivotally installed in the two shafts
13
a
through the axial holes
42
a
so that the wire winding disks
4
a
can rotate in the wire groove
11
a.
The communication wire
3
a
has two ends each being installed with a plug
31
a
and an earphone
32
a
. The two ends of the communication wire
3
a
may be wound as two parts for matching in the two wire grooves
11
a
of the box body
1
a
. The middle part of the communication wire
3
a
passes through the groove holes
11
a
on the shafts
13
a
in the two wire grooves
11
a
. Therefore, the two ends of the communication wire
3
a
are disposed in the two wire grooves
11
a
. The communication wire
3
a
can be wound around the exterior
47
a
and interior
48
a
(see
FIG. 2
) of the wire winding ring
44
a
of the wire winding disk
4
a
. The plug
31
a
and earphone
32
a
at two ends of the communication wire
3
a
are protruded out from the wire holes
12
a
of the box body
1
a.
Two spiral springs Sa are suitably installed in the two wire grooves
11
a
of the box body
1
a
respectively supported by support seats
7
a
. The buckling end
51
a
of each spiral spring
5
a
is buckled to the buckling hole
45
a
of the wire winding disk
4
a
. As the wire winding disk
4
a
rotates, the spiral spring
5
a
will store potential energy.
A wire winding box
4
can be assembled where the wire groove
11
a
serves to receive a section of the communication wire
3
a
having a relatively long length, and the section can be rewound as desired. The user may insert the plug
31
a
of the communication wire
3
a
to a receptacle of a relative communication device for downloading relative data. The two ends of the communication wire
3
a
can be pulled out directly from the wire winding box. The two ends of the communication wire
3
a
are pulled by the spiral spring
5
a
in the box so that a certain pulling force is retained thereon, and thus the communication wire
3
a
can be wound back into the box. Therefore, the wire is prevented from protruding out of the box when not in use.
In order to ensure that the user's pull of the communication wire
3
a
is not overly hindered by the tension of the winding force, the periphery of the wire winding disk
4
a
is installed with a plurality of buckling grooves
46
a
and a control device
6
a
. The control device
6
a
includes a swinging piece
61
a
swinging freely and a ratchet
62
a
rotating freely. By the special relationship connecting the swinging piece
61
a
, ratchet
62
a
, and the buckling groove
46
a
of the wire winding disk
4
a
, the communication wire
3
a
can be fixed or rewound by pulling and releasing.
However, in the prior art wire winding box, after the communication wire
3
a
passes through the groove holes
11
a
from the grove hole
14
a
, it winds around the shaft
13
a
in the interior
48
a
of the wire winding disk
41
a
, and then passes through the through hole
49
a
preset on the wire winding ring
44
a
to the exterior
47
a
of the wire winding ring
44
a
. Then, it protrudes out from the wire hole
12
a
to the outer side of the wire winding box. When one end of the communication wire
3
a
is pulled out from the wire winding box, it will at first pull the communication wire
3
a
wound around the exterior
47
a
of the wire winding ring
44
a
. Then, the interior
48
a
of the wire winding ring
44
a
will be pulled out until the communication wire
3
a
of the exterior
47
a
of the wire winding ring
44
a
is fully pulled out. Then, it pulls the communication wire
3
a
on the shaft
13
a
wound in the interior
48
a
of the wire winding ring
44
a
. When the communication wire
3
a
is wound back to the wire winding box, the communication wire
3
a
will wind around the exterior
47
a
(
FIG. 2A
) of the wire winding ring
44
a
, and at the time that the communication wire
3
a
winds around the exterior
47
a
of the wire winding ring
44
a
, the communication wire
3
a
may wind around the shaft
13
a
of the interior
48
a
of the wire winding ring
44
a
. The section of the communication wire
3
a
wound around the interior
48
a
of the wire winding ring
44
a
is provided by the communication wire
3
a
wound around the exterior
47
a
of the wire winding ring
44
a
(see FIG.
2
B). However, when the communication wire
3
a
wound around the exterior
47
a
of the wire winding ring
44
a
is pulled, significant friction will occur between different sections of the communication wire
3
a
and between the communication wire
3
a
and the wire winding ring
44
a
. Such friction will induce damage to the surface of the communication wire
3
a
; therefore, the interior lead will be damaged so that the life of the communication wire
3
a
and the whole wire winding box will be reduced.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a wire winding box for reducing radial friction, and especially to a wire winding box for reducing radial friction of a communication wire. A fixing piece is installed in the through hole in the wire winding ring of the 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 cannot 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 cannot be pulled out. Therefore, as the communication wire is wound back into the wire winding box, it only winds around the exterior of the wire winding ring and not wound in the interior of the wire winding ring. The friction between different sections of the communication wire and between the communication wire and the wire winding ring will not occur. Therefore, the friction, which induces damage to the surface of the interior lead of the communication wire, will be avoided and, thus, the life of the communication wire and of the whole wire winding box will be increased. The communication wire and the whole wire winding box will have a longer
