ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a positioning device of a wire groove in a wire winding box, and especially to a wire winding box for automatically winding a communication wire and receiving the communication wire therein.
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 avoid the communication wire is too long to be wound together or too short to be insufficient in using, there are various wire winding boxes being designed. In general, the wire winding box includes a box body, a housing, a communication wire, two wire winding disks; and two spiral springs. Therefore, the plug of the communication wire can be inserted into the communication devices for downloading data.
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 disks
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 a proper place for being protruded by the plug
31
a
and earphone
32
a
at two ends of the communication wire
3
a.
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
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
.
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
14
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
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
5
a
are properly installed in the two wire grooves
11
a
of the box body
1
. 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
so that the two spiral springs
5
a
are connected to the two wire winding disks
4
a.
As the wire winding disk
4
a
rotates, the spiral spring
5
a
will store dynamic energy.
Thereby, a wire winding box
4
can be assembled, in practical, the wire groove serves to receive a section of the communication wire
3
a
having a relative 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 to the box. Therefore, the wire will not expose out and wind together.
In order to avoid that as the user pull the communication wire
3
a,
it will not be interfered 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 reaction connected 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
passes through the groove holes, it is directly wound around the shaft
13
a
and the wire winding disk
4
a
(see FIG.
2
). Since the middle portion of the communication wire
3
a
does not been positioned, when one end of the communication wire
3
a
is pulled out from the wire winding box, it is very possible to affect another end. That is, another end will reduce into the box so that two ends of the communication wire
3
a
can not be retained in a proper length to be pulled out. Therefore, it is very possible that one end is pulled out with an overlong length, while another end is pulled out with an insufficient length.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a positioning device of a wire groove in a wire winding box, in which when one end of the communication wire is pulled from the wire winding box, another end will not be affected. That is, another end will not reduce into the box body. Therefore, two ends of the communication wire may retain a predetermined length to expose out. The condition that one end is pulled out with a overlong length, while the other end is pulled out with an insufficient length does not occur.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when reading in conjunction with the appended drawing.
