Description

Technical Field

[0001] This utility model relates to a reel. Background Technology

[0002] A wire reel is a tool used for organizing, storing, and transporting wires, cables, or other conduits, and is widely used in electrical connections, signal transmission, and logistics storage. An optical cable is a communication cable assembly used to transmit optical signals, while a cable is a wire product used to transmit electrical energy, information, or realize the conversion of electromagnetic energy. Both optical cables and cable play a vital role in national construction and the national economy.

[0003] During the laying of optical and electrical cables, they are wound onto reels for convenient storage and transportation. Optical and electrical cables with larger outer diameters are therefore larger in volume and weight, and thus wooden reels are used. To ensure the strength of the reels, an iron frame is also installed within them. However, the current manufacturing process for wooden reels is quite cumbersome. It requires first welding the iron frame, then cutting multiple wooden strips of different specifications according to the design dimensions, and finally fixing the wooden strips to the iron frame to assemble the reel. This results in low production efficiency, high labor costs, and is time-consuming, labor-intensive, and expensive, leading to high manufacturing costs. Furthermore, wooden reels are prone to aging and cannot be recycled, requiring continuous consumption of wood resources, which is detrimental to the environment and warrants further improvement.

[0004] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a spool that greatly simplifies the manufacturing process, effectively improves production efficiency and reduces labor costs, thereby achieving the effect of saving time, effort and money, significantly reducing manufacturing costs, and also realizes multiple recycling to have low usage costs and is environmentally friendly.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a spool, characterized in that it includes a winding cylinder and two discs that are detachably fixed at the openings at both ends of the winding cylinder and are concentrically arranged with the winding cylinder.

[0006] An annular cavity is formed on the outer wall of one end face of the disk, and a first annular grid area is provided in the annular cavity to increase the strength. The annular cavities on the two disks are arranged opposite to each other or back to back.

[0007] When the annular cavities on the two discs are opposite each other and both are positioned in the direction of the winding drum, an annular cover plate is fixed at the opening of each annular cavity on the two discs.

[0008] When the annular cavities on the two discs are opposite to each other and both are set in the opposite direction to the winding drum, the openings of the annular cavities on the two discs are also fixed with several arc-shaped cover plates arranged sequentially along the circumference.

[0009] One of the disks also has a thread hole between the outer walls of its two end faces.

[0010] Preferably, an extension block is formed on the inner wall of the annular cavity on the disk where the thread hole is located, facing into the annular cavity. Correspondingly, a first notch that cooperates with the extension block is provided on the inner circumferential surface of the annular cover plate, and a second notch that cooperates with the extension block is provided on the arc-shaped inner wall of the arc-shaped cover plate located at the extension block.

[0011] Preferably, a V-shaped groove is formed on the outer wall of one end face opposite to the winding drum on a disc where the threading hole is located, and the groove is recessed into the extension block. A through hole is formed on the bottom surface of both ends of the V-shaped groove. The threading hole is located between the bottom surface of the middle part of the V-shaped limiting groove and the outer wall of the extension block facing the winding drum.

[0012] Preferably, each of the discs has a concentric convex ring formed on the outer wall of one end face near the winding drum, and the two ends of the winding drum are respectively fitted over the convex rings on the two discs.

[0013] Preferably, on the outer wall of one end face of each disk near the winding drum, a bushing is formed concentrically inside the convex ring and facing the winding drum.

[0014] Preferably, the inside of the winding drum is further provided with a plurality of support rods evenly distributed at equal angles along the circumference. Each support rod is attached to the inner wall of the winding drum, and the two ends of each support rod are detachably fixed to two discs, thereby detachably fixing the winding drum between the two discs.

[0015] Preferably, the disc, the winding spool, the annular cover plate, and the arc-shaped cover plate are all made of bamboo-plastic composite material.

[0016] Preferably, a detachable flexible protective plate, made of bamboo-plastic composite material, is also wound between the two discs.

[0017] Compared with the prior art, the advantages of this utility model are as follows: The disc, winding spool, annular cover plate, and arc-shaped cover plate of this utility model are all made of bamboo-plastic composite material and manufactured by injection molding. After injection molding, the disc, winding spool, annular cover plate, and arc-shaped cover plate can be simply assembled together, which greatly simplifies the manufacturing process, effectively improves production efficiency, and reduces labor costs, thereby achieving the effect of saving time, effort, and money, and significantly reducing manufacturing costs.

[0027] An annular cavity 12 is formed on the outer wall of one end face of the disk 1 to save material. The annular cavity 12 is also provided with a first annular grid area 13 to increase strength. The annular cavities 12 on the two disks 1 are arranged opposite to each other or back to back.

[0028] When the annular cavities 12 on the two discs 1 are opposite each other and both face the winding drum 2, an annular cover plate 3 is fixed at the opening of the annular cavity 12 on the two discs 1. The purpose of this arrangement is to cover the first annular grid area 13 to form a plane. When the cable is wound around the winding drum 2 and located between the two discs 1, the outer sheath of the cable that was originally in direct contact with the first annular grid area 13 will have an imprint due to pressure. After the first annular grid area 13 is covered, the imprint will not be produced.

[0029] When the annular cavities 12 on the two discs 1 are opposite to each other and both are set in the opposite direction to the winding drum 2, several arc-shaped cover plates 4 are fixed at the openings of the annular cavities 12 on the two discs 1 in sequence along the circumference. The outer wall of each arc-shaped cover plate 4 is used to stick a label displaying the cable parameters. If the arc-shaped cover plate 4 is not set, the label cannot be pasted on the first annular grid area 13.

[0030] One of the discs 1 has a wire hole 14 between the outer walls of the two end faces. The wire hole 14 is used to allow one end of the cable to pass out and be fixed.

[0031] An extension block 16 is formed on the inner wall of the annular cavity 12 on a disc 1 where the thread hole 14 is located, facing the interior of the annular cavity 12.

[0038] Each support rod 5 has its two ends inserted into two discs 1, and each support rod 5 also has a nut 6 screwed onto its two ends. Each nut 6 is pressed onto the corresponding disc 1 and is opposite to the outer wall of one end face of the winding drum 2.

[0039] On the outer wall of one end face opposite to the winding drum 2, each disc 1 has multiple bowl-shaped countersunk holes 19 evenly distributed at equal angles along the circumferential direction on the inner side of the convex ring 17. The number of bowl-shaped countersunk holes 19 is equal to the number of support rods 5.

[0040] Each bowl-shaped countersunk hole 19 has a through hole 110 between its bottom center and the outer wall of one end face of the corresponding disc 1 near the winding drum 2. The two ends of each support rod 5 are respectively inserted into the corresponding through holes 110 on the two discs 1. Each nut 6 is located in a corresponding bowl-shaped countersunk hole 19 and is pressed against the bottom surface of the bowl-shaped countersunk hole 19.

[0041] Each support rod 5 is also fitted with a bowl-shaped washer 7 at both ends. Each bowl-shaped washer 7 is embedded in a corresponding bowl-shaped countersunk hole 19. Each nut 6 is located in a corresponding bowl-shaped washer 7 and is pressed against the bottom inner wall of the bowl-shaped washer 7 to prevent the nut 6 from damaging the inner wall of the bowl-shaped countersunk hole 19 when tightening.

[0042] Multiple reinforcing ribs 21 are formed on the inner wall of the winding drum 2 at equal angles along the circumference, and each reinforcing rib 21 is arranged parallel to the central axis of the winding drum 2.

[0047] How to use:

[0048] Pass one end of the cable or optical fiber through the through hole 14 from the inside out and embed it in the V-shaped groove 15. Then pass it through the two through holes 111 in sequence to fix one end of the cable or optical fiber. Then, wind the cable or optical fiber onto the winding spool 2 one turn at a time. After winding, use a flexible protective plate 8 to wind between the two discs 1 to wrap the cable or optical fiber. Finally, tie several packing straps 9 around the outside of the wound flexible protective plate 8 to fix it.

[0049] If the disc 1 or the winding drum 2 is damaged after multiple uses, the detachable structure design of this utility model can be used to remove the damaged disc 1 or the winding drum 2 and then replace it with a new disc 1 or the winding drum 2, thereby realizing recycling and saving materials.

[0050] Since the disc 1, winding drum 2, annular cover plate 3, arc-shaped cover plate 4, and flexible protective plate 8 are all made of bamboo-plastic composite material, the cost is low. Moreover, due to the inclusion of plastic, it can be manufactured quickly and precisely using injection molding, greatly improving production efficiency. In addition, bamboo-plastic composite material also has the characteristics of smooth surface, dense texture, excellent mechanical properties, corrosion resistance, insect resistance, and low water absorption, thus enabling long-term recycling.

[0051] The disc 1, winding drum 2, annular cover plate 3, and arc-shaped cover plate 4 of this utility model are all made of bamboo-plastic composite material and manufactured through injection molding. After injection molding, the disc 1, winding drum 2, annular cover plate 3, and arc-shaped cover plate 4 can be simply assembled together, which greatly simplifies the manufacturing process, effectively improves production efficiency, and reduces labor costs, thus achieving the effect of saving time, effort, and money, and significantly reducing manufacturing costs. In addition, since the disc 1 and winding drum 2 are fixed in a detachable manner, and the bamboo-plastic composite material ensures the strength and wear resistance of the spool due to its unique properties, multiple recycling is achieved. Once damaged, only the damaged parts need to be replaced, instead of replacing the whole spool, resulting in lower usage costs. At the same time, it does not consume precious wood resources, which is beneficial to environmental protection.
