Description

Technical Field

[0001] This utility model relates to the field of winding reels, and specifically to a liftable winding reel. Background Technology

[0002] Cables are a fundamental raw material in fields such as power and communications. During the production process, manufactured cables need to be wound onto cable reels for storage and transportation. Cable reels are a common tool used for winding cables. Cable reels are generally made of plastic and are typically manufactured using injection molding. A cable reel consists of an upper reel and a lower reel spaced apart, connected by a cylindrical structure. The upper and lower reels, along with the external space of the cylindrical structure, form a winding space for winding cables. The middle of the cylindrical structure is open from top to bottom.

[0003] In practical applications, after the cable is wound onto the reel, it is often necessary to take the cable to the work site for tasks such as cable laying. Existing reels are difficult to move during operation, especially when they are fully wound with cable, as their weight makes them difficult to handle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a liftable winding reel with a handle structure, which enables flexible handling of the winding reel fully wound with cables during operation, and the reel body and the cylinder adopt a rotating screw-in insertion connection structure to achieve quick assembly and disassembly.

[0005] The technical solution adopted by this utility model is as follows: A liftable winding reel includes a first reel and a second reel arranged in parallel at intervals, and a cylinder connected between the first reel and the second reel in the axial direction. A winding space is formed between the first reel, the second reel, and the cylinder for winding cables. Inner support rings extending inward in the radial direction are provided at both ends of the cylinder. Lifting blocks are provided in the inner support rings. The lifting blocks extend in the radial direction of the cylinder and pass through the axis of the cylinder for lifting the winding reel. The lifting blocks divide the interior of the inner support rings into two insertion spaces that are axially connected. The cylinder is connected and fixed to the first reel and the second reel respectively by connecting components.

[0006] Preferably, the lifting block has an axial through hole in its center.

[0007] Preferably, the connecting assembly includes a mating connecting ring and a connecting ring groove, wherein the mating connecting ring is disposed on the disk surface of the first disk and the second disk and is concentric with the first disk and the second disk; the mating connecting ring extends axially and its outer diameter is not greater than the inner diameter of the cylinder so as to be inserted into the cylinder; the connecting ring groove is a circular groove and is disposed on the outside of the mating connecting ring, and the connecting ring groove is recessed inward into the interior of the first disk or the second disk so as to be inserted into the cylinder.

[0008] Preferably, the inner side of the interlocking connecting ring is provided with a support component; the support component includes an inner extension ring and ribs, wherein the inner extension ring is disposed on the inner side of the interlocking connecting ring and extends inward in the radial direction; the ribs include at least two pieces, which are spaced apart on the inner extension ring in the circumferential direction and connected to the inner wall of the interlocking connecting ring for bearing support.

[0009] Preferably, the connecting assembly further includes an insertion slot and a connecting block, wherein the insertion slot includes at least two slots, which are formed on the connecting ring groove along the circumferential direction and extend outward; the connecting block includes at least two blocks, which are respectively arranged on the outer side wall of the cylinder along the circumferential direction. The connecting block is inserted into the connecting ring groove through the insertion slot, and by rotating the cylinder relative to the first disc or the second disc, the connecting block slides into the connecting groove, offset from the insertion slot, for axially clamping and limiting the cylinder and the first disc or the second disc.

[0010] Preferably, the connecting block has an inclined protrusion on the side wall near the middle of the cylinder. The inclined protrusion protrudes radially and is used to radially clamp and limit the connecting block in the connecting ring groove.

[0011] The beneficial effects of this utility model are as follows: This utility model addresses the shortcomings and deficiencies of existing technologies by independently developing and designing a liftable winding reel with a handle structure, which enables flexible handling of the fully wound cable reel during operation. Furthermore, the reel body and the cylinder adopt a rotating and screwing insertion connection structure, enabling quick assembly and disassembly.

[0012] This invention addresses the need for on-site cable pulling and unwinding after the cable is fully wound during actual work. It designs a portable cable reel for easy and convenient transport between different work sites. Specifically, the reel has inwardly extending annular inner support rings at both ends. A lifting block is located radially in the center of each inner support ring, dividing the central space into two symmetrical insertion spaces. This allows the user to grasp the lifting block through these spaces and lift the reel as a whole. An axial insertion slot is formed in the center of the lifting block, facilitating the insertion of a rod during operation to allow for cable rotation and unwinding. Furthermore, the two ends of the cylindrical body of this invention are connected to the first and second disc bodies via connecting components. The connecting components include interlocking connecting rings disposed on the surface of the first or second disc body and connecting ring grooves disposed outside the interlocking connecting rings. The interlocking connecting rings are concentrically positioned with the first or second disc surface, and their outer diameter is not greater than the inner diameter of the cylindrical body. During assembly, the cylindrical body is axially inserted into the interlocking connecting rings, the interlocking connecting rings penetrate the cylindrical body, and the cylindrical body is inserted into the connecting ring grooves, thus connecting the cylindrical body with the first and second disc bodies to form an integral winding reel. Even further, an inwardly extending annular inner ring is provided on the inner side of the interlocking connecting ring. Multiple ribs are spaced apart along the circumference of the inner ring, and these ribs are connected to the inner ring and the interlocking connecting ring respectively, serving to support and reinforce the interlocking connecting ring. Furthermore, this utility model features a plurality of insertion slots spaced apart on the connecting ring groove, and correspondingly, a plurality of connecting blocks are provided on the outer wall of the cylinder. When the cylinder is inserted into the first or second disc, the connecting blocks are inserted from the insertion slots. Then, the cylinder and the first or second disc are rotated relative to each other, causing the connecting blocks to be inserted into the connecting ring groove at different insertion slots, so as to axially clamp and limit the cylinder and the first or second disc. Furthermore, a radially inclined protrusion can be provided on the end face of the connecting block near the middle of the cylinder. The protrusion can be made of flexible plastic material. When the connecting block is screwed inward into the connecting ring groove from the insertion slot direction, the protrusion is squeezed, thereby radially clamping and limiting the connecting blocks through a reaction force, that is, radially clamping and limiting the cylinder and the first or second disc to ensure connection stability.

[0028] The present invention will now be further described with reference to the accompanying drawings: Example 1

[0029] like Figures 1 to 6As shown, the technical solution adopted in this embodiment is as follows: A liftable winding reel includes a first reel body 1 and a second reel body 2 arranged in parallel and spaced apart, and a cylindrical body 3 connected between the first reel body 1 and the second reel body 2 in the axial direction. A winding space is formed between the first reel body 1, the second reel body 2 and the cylindrical body 3 for winding cables. Inner support rings 4 extending inward in the radial direction are provided at both ends of the cylindrical body 3. Lifting blocks 5 are provided in the inner support rings 4. The lifting blocks 5 extend in the radial direction of the cylindrical body 3 and pass through the axis of the cylindrical body 3 for lifting the winding reel. The lifting blocks 5 divide the interior of the inner support rings 4 into two insertion spaces that are axially connected. The cylindrical body 3 is connected and fixed to the first reel body 1 and the second reel body 2 respectively by connecting components.

[0030] The middle part of the lifting block 3 has an insertion hole A that runs through the axial direction.

[0031] The connecting assembly includes a mating connecting ring 6 and a connecting ring groove B. The mating connecting ring 6 is disposed on the disk surface of the first disk 1 and the second disk 2, and is concentric with the first disk 1 and the second disk 2. The mating connecting ring 6 extends axially and its outer diameter is not greater than the inner diameter of the cylinder 3, so as to be inserted into the cylinder 3. The connecting ring groove B is a circular groove and is disposed on the outside of the mating connecting ring 6. The connecting ring groove B is recessed inward into the interior of the first disk 1 or the second disk 2, so as to be inserted into the cylinder 3.

[0032] The inner side of the interlocking connecting ring 6 is provided with a support component; the support component includes an inner extension ring 7 and ribs 8, wherein the inner extension ring 7 is disposed on the inner side of the interlocking connecting ring 6 and extends inward in the radial direction; the ribs 8 include at least two pieces, and the at least two ribs 8 are disposed at intervals along the circumferential direction on the inner extension ring 7 and connected to the inner wall of the interlocking connecting ring 6 for bearing support. Example 2

[0033] like Figures 7 to 14 As shown, this embodiment further improves the connecting component compared to embodiment 1. In embodiment 1, after the cylinder 3 is inserted into the connecting ring groove B, the heat generated by rotation can cause the material of the contact surface between the mating connecting ring 6 and the cylinder 3 to fuse and bond together.

[0034] This embodiment adopts a physical connection method. Specifically, the connection component of this embodiment also includes an insertion slot C and a connecting block 9. The insertion slot C includes at least two slots, which are opened in the connecting ring groove B along the circumferential direction and extend outward. The connecting block 9 includes at least two blocks, which are respectively arranged on the outer side wall of the cylinder 3 along the circumferential direction. The connecting block 9 is embedded in the connecting ring groove B through the insertion slot C. By rotating the cylinder 3 relative to the first disc 1 or the second disc 2, the connecting block 9 slides into the connecting groove B, offset from the insertion slot C, for axially clamping and limiting the cylinder 3 and the first disc 1 or the second disc 2.

[0035] The connecting block 9 has an inclined protrusion 10 on its side wall near the middle of the cylinder 3. The inclined protrusion 10 is inclined and protrudes in the radial direction to radially clamp and limit the connecting block 9 in the connecting ring groove B.

[0036] Furthermore, this utility model designs a reel with a handle structure, enabling flexible handling of the fully wound cable reel during operation. The reel body and cylinder employ a rotating and screwing insertion connection structure, allowing for quick assembly and disassembly of the portable reel. This utility model addresses the need for on-site cable pulling and unwinding after the cable is fully wound, designing a portable reel for convenient and flexible transport between different work sites. Specifically, the cylinder has inwardly extending annular inner support rings at both ends. A lifting block is radially positioned in the center of each inner support ring, passing through the center of the inner support ring and dividing the central space into two symmetrical insertion spaces. This allows the user to grasp the lifting block through these spaces and lift the reel as a whole. An axially penetrating insertion slot is formed in the center of the lifting block, facilitating the insertion of a rod during operation for easy cable unwinding from the reel. Furthermore, the two ends of the cylindrical body of this invention are connected to the first and second disc bodies via connecting components. The connecting components include interlocking connecting rings disposed on the surface of the first or second disc body and connecting ring grooves disposed outside the interlocking connecting rings. The interlocking connecting rings are concentrically positioned with the first or second disc surface, and their outer diameter is not greater than the inner diameter of the cylindrical body. During assembly, the cylindrical body is axially inserted into the interlocking connecting rings, the interlocking connecting rings penetrate the cylindrical body, and the cylindrical body is inserted into the connecting ring grooves, thus connecting the cylindrical body with the first and second disc bodies to form an integral winding reel. Even further, an inwardly extending annular inner ring is provided on the inner side of the interlocking connecting ring. Multiple ribs are spaced apart along the circumference of the inner ring, and these ribs are connected to the inner ring and the interlocking connecting ring respectively, serving to support and reinforce the interlocking connecting ring. Furthermore, this utility model features a plurality of insertion slots spaced apart on the connecting ring groove, and correspondingly, a plurality of connecting blocks are provided on the outer wall of the cylinder. When the cylinder is inserted into the first or second disc, the connecting blocks are inserted from the insertion slots. Then, the cylinder and the first or second disc are rotated relative to each other, causing the connecting blocks to be inserted into the connecting ring groove at different insertion slots, so as to axially clamp and limit the cylinder and the first or second disc. Furthermore, a radially inclined protrusion can be provided on the end face of the connecting block near the middle of the cylinder. The protrusion can be made of flexible plastic material. When the connecting block is screwed inward into the connecting ring groove from the insertion slot direction, the protrusion is squeezed, thereby radially clamping and limiting the connecting blocks through a reaction force, that is, radially clamping and limiting the cylinder and the first or second disc to ensure connection stability.

[0037] The embodiments of this utility model are merely illustrative of specific implementation methods and are not intended to limit its scope of protection.
