[Embodiment of the invention]

 The configuration of the present invention will be described in detail with reference to the accompanying drawings. Reference numeral 8 denotes a handle insertion hole, 14 denotes a shaft hole, and 15 denotes a long bolt hole.

A drum and a shaft plate are manufactured by extruding waste plastic (polyethylene and polypropylene), and the drum is manufactured from a front drum 1 and a back drum 2 which are formed by dividing a cylindrical shape into two vertically. Also, the left and right plates 3 and 4 are assembled on the left and right sides of the drums 1 and 2 and have two handle insertion holes 8 and four long bolt holes 15 and shaft holes 14, respectively. The drum according to the present invention is constructed by assembling the four long bolts 16, the nut 18 and the washers 17, 17 '.

As shown in FIG. 3, the front drum 1 and the back drum 2 each have a plurality of long reinforcing ribs 7 formed on the inside thereof. A semi-circular reinforcing rib 6 having two long bolt holes 15 'is formed so that the long bolt 16 can be inserted when the side plates 3, 4 and the drums 1, 2 are assembled. Further, by forming two conical mating projections 5 and 5 'on both end portions, the mating projections 5 and 5' are connected to the drums of the left and right side plates 3 and 4 when assembling with the left and right side plates 3 and 4. The long bolt holes 15 and 15a can be easily fitted by assembling them by fitting them into the mating projection grooves 19 formed in the groove 9 so that the assembling becomes easy.

As shown in FIG. 3, the left and right side plates 3, 4 penetrate through one side of the deflected portion at the center to form a starting port 12, and the ends of the electric wires or cables passing through the starting port 12. The wire insertion part 20 is formed near the starting end port 12 so that the part can be inserted. A plurality of name tag fastening pins 13 and 13 'are provided on upper and lower portions of the outer side surfaces of the left and right side plates 3 and 4 for sandwiching the name tags. Circular drum couplings formed in the outer periphery of the back side shaft holes 14 of the left and right plates 3 and 4 so that the ends of the drums 1 and 2 can be press-fitted and fixed when the drums 1 and 2 are assembled. The groove 9 is formed, and a mating projection groove 19 into which the mating projections 5 and 5 'of the drums 1 and 2 are fitted is formed in the drum coupling groove 9 as shown in FIG. This makes it easy to align the long bolt holes 15 and 15a with each other, and simplifies assembly.

Circular anti-shrinkage grooves 10 and 11 are provided on the inner and outer circumferences of the drum connecting groove 9 for preventing the drum connecting groove 9 from contracting and distorting during drying and shrinking after injection molding. It is formed concentrically. The number of the alignment projections 5 and 5 'and the alignment projection groove 19 is not limited to four as shown, but is arbitrary.

When assembling the present invention configured as described above, as shown in FIG. 4, the ends of the drums 1 and 2 are inserted into the drum coupling grooves 9 of the left and right side plates 3 and 4, and then the drums 1 and 2 are inserted. 2 is appropriately rotated so that the mating projections 5 and 5 'formed on the drums 1 and 2 and the mating projection grooves 19 of the left and right side plates 3 and 4 meet, and the mating projections 5 and 5' are fitted into the mating projection grooves 19. When they are combined, the four long bolt holes 15a formed in the semicircular reinforcing rib 6 and the four long bolt holes 15 formed in the left and right side plates 3 and 4 are naturally aligned. Then, the long bolt 16 is inserted into these long bolt holes 15 and 15a, and the assembly is completed by tightening with the nut 18. Thus, the drum of the present invention is easy to assemble and requires less assembling time.

When winding an electric wire or a wire rope around the packaging drum assembled as described above, the end of the electric wire is passed through the starting end port 12 and inserted into the electric wire insertion portion 20. Thus, the end of the electric wire can be prevented from being exposed to the outside.

The drums 1 and 2 are vertically separated and are not divided into a front drum 1 and a rear drum 2, but are configured as integral cylindrical drums 1a and 2a as shown in FIG. You can also.

6 and 7 show different embodiments of the left and right side plates 3 and 4 of the present invention. The left and right side plates 3a and 4a shown in FIG. 6 have outer peripheral surfaces formed in a non-circular polygonal shape. Thus, the packaging drum can be prevented from rolling, and can be kept stationary at the original place. As shown in FIG. 7, the outer surfaces of the left and right side plates 3b, 4b may be formed in a non-radial checkerboard shape.

FIG. 8 shows still another embodiment of the present invention, in which left and right side plates 3c, 4c are formed with drum connecting grooves 9 'and contraction preventing grooves 10', 11 'having a polygonal structure. Is performed. Plungers 21 each having two long bolt holes 15b formed at both end portions of the drums 1b and 2b are connected to each other, and polygonal drum coupling parts 22 and 22 'are formed on the upper part of the plunge 21. The projections 5 and 5 'are formed on the upper portions of the drum coupling portions 22 and 22'. The drum coupling portions 22 and 22 'are formed in the drum coupling grooves 9' of the left and right side plates 3c and 4c. Is inserted and assembled and fixed.

FIG. 9 shows still another embodiment of the drum according to the present invention. The drums 1 and 2 are not divided into two parts, but are divided into a plurality of drum assembly plates 23. 9 is formed on the inner surface of the drum assembly plate 23 as shown in FIG. 9, and four drum assembly plates 23 are formed on both side surfaces. A drum assembling plate 23 'having the projections 5 and 5' is provided.

A drum assembly disk 24 is used to connect and fix the plurality of drum assembly plates 23, 23 '. The drum assembly disk 24 has a shaft hole 14 'at the center and four long bolt holes 15c at the outer peripheral edge. A part of the outer peripheral surface of the drum assembling disk 24 is provided with a drum plate fixing frame 25 having a wide and narrow inside and outside, in which a disk opening part 26 is formed so that the above-mentioned drum assembling plates 23 and 23 'can be inserted. The plurality of drum assembling plates 23, 23 'are positioned at the disk opening portion 26 and are sequentially engaged with the drum plate fixing frame 25 by being connected in series, thereby forming a drum. After assembling, the drum assembly plate 23 to be assembled last is assembled by fixing it to the outside of the disk opening portion 26 with nails, screws, or the like.

The present invention is manufactured by extruding waste plastic (polyethylene and polypropylene), and can be manufactured and used by changing the size according to the type of electric wire or wire rope to be wrapped. , The number of washers and nuts can be variously increased or decreased depending on the type of drum and operating conditions. In addition, the present invention can be manufactured not only by waste plastic extrusion molding but also by working methods such as casting, aluminum, die casting, etc., and the manufacturing method can be appropriately selected according to the use application of the drum.
