Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric wire winding drum around which electric wire is wound.

Conventionally, in work such as replacing electric wires, the wire winding drum that winds up existing electric wires is connected at its winding drum so that it can be separated into left and right sides, and after the wound electric wires are tied into a bundle, , the wire is disassembled and the wire is disposed of, while the wire winding drum is reassembled. However, in the above-mentioned wire winding drum, the winding drum is vertically divided at the center and the ends are butted and connected, so when the wire is wound, the wire may bite into the divided portion. There was a problem that the work became complicated.

The present invention has been made in view of this point, and includes a plurality of frames protruding from each of the opposing side frames to form a winding drum, and the tips of the left and right frames are crossed and connected. This provides an electric wire winding drum that can wind the electric wire without biting into the divided portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 5, 1 is a wire winding drum that can be disassembled into left and right parts.
Existing electric wires etc. will be wrapped around it. The wire winding drum 1
connects the left and right frames 4, 5 to the winding drum 6 formed by the opposing left frame 2 and right frame 3 and the left frame 4 and right frame 5 fixed to the left and right side frames 2, 3 at their tips. It consists of a connecting means 7 that
The drum shaft 1a is inserted.

The left side frame 2 has a plurality of spokes 9 radially connected to a disc-shaped boss 8 at its inner ends, and an annular rim 10 connected to the outer ends of the spokes 9. A plurality of the left frames 4 are fixed at their base ends in a circular arrangement on the periphery. The left frame 4 protrudes inward and is slightly inclined toward the axis of the drum shaft 1a toward the tip, and its tip is fixed to the outer peripheral end of the flange 11. A cylindrical bearing member 12 into which the drum shaft 1a is fitted is inserted and fixed between the flange 11 and the boss 8, and a groove-shaped member 13 opening outward is provided between the outer peripheral ends. A plurality of groove-shaped members 13 are fixed at both ends, and wires, etc. for binding electric wires are inserted through the groove-shaped member 13, and the groove-shaped member 13 is located between the left frame 4.

The right side frame 3 has a large opening 1 in the center.
A plurality of spokes 16 are radially connected at their inner ends to a boss 15 having a diameter of 4, and an annular rim 17 is connected to the outer end of the spokes 16. A plurality of the right frames 5 are fixed at their base ends. The right frame 5 protrudes inward and is slightly inclined toward the axis of the drum shaft 1a as it approaches the tip, and its tip is fixed to the outer peripheral end of the flange 18. The flange 18 is open at the center, and a concave notch 18a is formed at the outer periphery between the right frames 5, and a wire for bundling electric wires or the like is inserted through the notch 18a.

The connecting means 7 connects the left and right frames 4 and 5 with their tips crossing each other, and has an annular left fitting member 19 and a right fitting member 20 fixed to the flanges 11 and 18, The left fitting member 19 is inserted into the right fitting member 20, and the right fitting member 2
The end face of 0 contacts the flange 11. Two protruding pieces 21 are fixed to the inside of the left fitting member 19, and the two protruding pieces 21 are located on a spiral line and are formed at about one quarter of the inner circumference. Above left fitting member 1
The connecting member 22 that is screwed into the member 9 is a disk-shaped base 23.
An annular connecting member 24 is fixed on the inside of the drum, a lever mounting portion 25 is provided on the outside, and a drum shaft 1 is installed in the center.
An opening 26 is formed through which a passes through. The connecting member 24 is inserted into the left fitting member 19, and two protruding pieces 27 are fixed to the outside.
7 is located on the spiral and is formed at about one quarter of the outer circumference. The lever mounting portion 25 has a cylinder 29 provided on the periphery of the base 23 with a holding member 28 in between, and the cylinder 29 has a lever 30 passed through it and is slightly inclined.
It is provided so as not to protrude from the right side frame 3, and the cylindrical body 2
A support member 32 having a through hole 31 is fixed to the periphery of the base 23 on the extension of the support member 9 .

Next, to explain the assembly operation, the left and right frames 4 and 5 are inserted between the tips of the left and right frames 4 and 5 so that their tips intersect with each other to form the winding drum 6, and the left fitting member 19 is inserted into the right Insert the connecting member 24 into the fitting member 20 and then insert the connecting member 24 into the left fitting member 19
Insert into. At that time, both protruding pieces 21 and 27 are positioned in a space between each other so that they do not come into contact with each other, and then, when the lever 30 is inserted into the cylinder body 29 and the through hole 31 and the base 23 is rotated, both the protruding pieces 21 and 27
are screwed together, and the protruding piece 27 and the base 23 are connected to the flange 1.
8 and the protruding piece 21, the left and right side frames 2 and 3 and the left and right frames 4 and 5 are connected.
Moreover, when disassembling it, the above operation can be performed in reverse.

As described above, according to the wire winding drum of the present invention,
The winding drum is formed by connecting multiple left and right frames that protrude from each of the opposing side frames so that their tips intersect, making it possible to wind up the wire without digging into it, simplifying the work. Moreover, since it is constructed with a rolled frame, the overall weight is light. In addition, if the connecting means is structured so that the connecting member is screwed into a fitting member connected to the tip of the frame, disassembly and assembly operations can be performed very easily. By using this, the starting and ending ends of the electric wires can be wrapped around the spokes, so the work can be done quickly and the work of binding the electric wires can be done easily.
