Description

Technical Field

[0001] This utility model belongs to the technical field of cable storage devices, specifically relating to a detachable cable reel with a locking function. Background Technology

[0002] Currently, cable reels, as storage devices for cables, ropes, and other materials, are widely used in power, telecommunications, and construction industries. However, traditional cable reels have several drawbacks: Firstly, one-piece cable reels, being integrally molded, are large and occupy a lot of space, requiring specific site conditions for placement. During transportation, they are not only difficult to fit into conventional transport vehicles but also increase transportation costs and difficulties due to their large size. Secondly, some cable reels use bolts to connect the reels, which, while simple in structure, are inconvenient to disassemble and maintain. For scenarios involving frequent cable replacement or repair, the disassembly and assembly are inefficient, increasing usage costs. Furthermore, while existing snap-on cable reels are easy to assemble, the snap-on structure is prone to loosening after high-speed rotation or prolonged use, causing the baffle to separate from the reel body, posing a safety hazard. Cable reels with threaded connections offer good stability, but the disassembly and assembly process is cumbersome, requiring tools and hindering rapid operation.

[0003] Therefore, there is an urgent need for a coil structure that can achieve quick assembly and disassembly, ensure a stable connection, and flexibly adapt to transportation and storage requirements to meet different application scenarios. Utility Model Content

[0004] This utility model proposes a wire reel that improves the snap-fit ​​connection method and adds a locking structure, effectively solving the problems of inconvenient disassembly and assembly and easy loosening in the prior art, thereby improving the practicality and reliability of the wire reel.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reel has a cylindrical body with circular discs on both sides. The circular discs are connected to the cylindrical body by a snap-fit ​​structure and fixed to the cylindrical body by a locking structure. The locking structure consists of a pin hole on the cylindrical body and a pin on the circular disc. After the pin is inserted into the pin hole, the circular disc is locked to the cylindrical body and cannot rotate.

[0007] Furthermore, the buckle structure consists of corresponding buckle blocks set on the cylinder and the circular disc, and the corresponding buckle blocks match and engage with each other.

[0008] Furthermore, the card block is tapered, and the mating is an interference fit.

[0009] Furthermore, the cylindrical body is composed of a left cylindrical body and a right cylindrical body that are fastened together. The left cylindrical body is provided with a protrusion, and the right cylindrical body is provided with a groove. The protrusion and the groove are matched and fastened together.

[0010] Furthermore, the protrusions or grooves are tapered, and the mating is an interference fit.

[0011] Furthermore, the locking structure is also equipped with a spring, the spring force of which presses the pin into the pin hole. When the pin is pulled out, the tension of the spring must be overcome to pull the pin out of the pin hole. A stop block is also provided so that the pulled-out pin can be fixed by the stop block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The cylinder adopts a left and right cylinder interlocking structure, with a tapered protrusion and groove interference fit design, which can be quickly disassembled and assembled without tools, significantly improving disassembly and assembly efficiency. After disassembly, each component can be stored independently, solving the problem of traditional integrated coils being bulky and inconvenient to transport and store. It is especially suitable for scenarios such as power construction and communication engineering that require frequent changes of work sites, greatly reducing transportation costs and space occupation.

[0014] The snap-fit ​​structure uses a tapered interference fit, which gives the circular disc and the cylinder reliable anti-separation performance when initially connected. This effectively avoids the problem of snap-fit ​​loosening caused by vibration during high-speed rotation or long-term use. The locking structure further locks the relative position of the disc and the cylinder through the cooperation of the pin and the pin hole, preventing them from rotating. This forms a dual stabilizing mechanism of "snap pre-positioning + pin rigid locking", which significantly improves the structural stability of the reel during the winding and unwinding process and eliminates safety hazards.

[0015] The spring device added to the locking structure continuously presses the pin into the pin hole through elasticity, ensuring the reliability of the locking state. When removing the pin, the spring tension must be overcome to prevent the pin from falling off due to accidental collision. The stop design provides a fixed fulcrum for the pin in the pulled-out state, making it easy for users to complete locking and unlocking with one hand. It takes into account both safety and convenience, and is especially suitable for operation scenarios that require frequent cable replacement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1-4 As shown, a spool includes a cylindrical body 1 and two circular discs 2 on both sides. The discs 2 are connected to the cylindrical body 1 by a snap-fit ​​structure 3. The locking structure 4 includes a pin hole 41 on the cylindrical body and a pin 42 on the disc, which prevents relative rotation after insertion.

[0024] The snap-fit ​​structure 3 consists of a cylindrical snap-fit ​​block 31 and a disc snap-fit ​​block 32, with the snap-fit ​​blocks 31 / 32 tapered to form an interference fit.

[0025] The cylinder 1 is composed of a left cylinder 11 (with a protrusion 111) and a right cylinder 12 (with a groove 121) that are fastened together. The convex and concave structure is tapered to achieve an interference fit.

[0026] The locking structure 4 is equipped with a spring 43 to press the pin 42, and a stop block 44 to fix the pulled-out state.

[0027] Working principle: Align the protrusion 111 of the left cylinder 11 with the groove 121 of the right cylinder 12. Because the protrusion or groove is tapered, pressure is applied to achieve an interference fit and fasten, forming a complete cylinder 1.

[0028] Align the baffle block 32 of the circular disc 2 with the cylinder block 31 of the cylinder 1, and use the taper of the block to press and engage the two in an interference fit to initially connect the disc and the cylinder.

[0029] The pin 42 on the circular disc 2 is inserted into the pin hole 41 of the cylinder 1 by the elastic force of the spring 43. At this time, the disc and the cylinder cannot rotate relative to each other, thus completing the overall installation of the coil.

[0030] The actuating pin 42 overcomes the tension of the spring 43, pulls the pin out of the pin hole 41, and then uses the stop block 44 to fix the pin in the pulled-out state, thereby releasing the rotation restriction between the disc and the cylinder.

[0031] Apply external force to pull, and use the separability of the latching structure 3 to separate the disc latching block 32 from the cylinder latching block 31, and remove the circular disc 2;

[0032] Optionally, if it is necessary to separate the cylinder 1, apply a larger external force and take advantage of the interference fit between the left cylinder protrusion 111 and the right cylinder groove 121 to separate the left cylinder 11 and the right cylinder 12, thus completing the disassembly of the coil.

[0033] In summary, the spool of this utility model provides an innovative solution with broad market application prospects.

[0034] It should be noted that the parts not covered by this utility model are the same as or can be implemented using existing technology.
