Description

Technical Field

[0001] This utility model belongs to the technical field of locking pin body and winding reel, specifically relating to a locking pin and assembled winding reel. Background Technology

[0002] Cable reels, used as packaging and storage containers for cables, wires, and other materials, are widely used in industrial production and logistics. For ease of handling and warehousing, modular cable reels have become the mainstream structure, typically assembled from a cylindrical body and reels at both ends via connectors. However, the existing locking mechanism used to connect the cylindrical body and reels still has significant drawbacks. For example, a locking mechanism and cable reel disclosed in prior art (CN210103175U), while achieving a detachable function, has a complex locking mechanism structure, including an independent mounting bracket and multiple components requiring precise fitting, such as a plug-in part, an elastic part, a locking part, and a pressing part. This structure not only has a cumbersome manufacturing process and high cost, but also, during frequent disassembly and assembly, the plastic material of the elastic part is prone to fatigue failure, leading to unreliable locking. Furthermore, it relies on the cooperation of the pressing part and the support part of the mounting bracket for unlocking, requiring ample operating space and making it inconvenient to use in confined or concealed installation locations.

[0003] Therefore, there is an urgent need to provide a locking pin and an assembled winding reel to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a locking pin and an assembled winding reel to solve the problems of complex structure, easy damage and limited application scenarios of the existing technology.

[0005] In a first aspect, the present invention provides a locking pin, including a locking pin body, the locking pin body including a plug part and a locking part, the locking part having a U-shaped slot in the middle, side fin locking blocks on both sides of the locking part, and a pressing block at the tail end of the locking part.

[0006] In conjunction with the first aspect, this utility model embodiment provides a first possible implementation of the first aspect, wherein two symmetrical contact blocks are provided in the U-shaped slot, and the contact blocks are close to the extrusion block.

[0007] In conjunction with the first aspect, this utility model embodiment provides a first possible implementation of the first aspect, wherein the upper end of the plug portion is provided with a slope.

[0008] In conjunction with the first aspect, the present utility model provides a first possible implementation of the first aspect, wherein a weight-reducing groove is provided on the back of the plug portion, and a reinforcing rib is provided in the weight-reducing groove.

[0009] Secondly, this utility model embodiment also provides an assembled winding reel, including a cylindrical body and reels disposed at both ends of the cylindrical body. The cylindrical body has protrusions at both ends, and the protrusions have first slots. The reels have second slots circumferentially along their centers, and the reels have grooves along their concentric circles. The grooves have through slots, the protrusions and grooves are matched, the first slots are aligned with the through slots in the grooves, and the locking pin body passes through the second slots and the first slots in sequence to connect the cylindrical body and the reels.

[0010] In conjunction with the second aspect, this utility model provides a first possible implementation of the second aspect, wherein the disc is provided with abutting blocks along its circumferential center, and the top end of the plug portion of the locking pin body is in contact with the abutting blocks.

[0011] In conjunction with the second aspect, this utility model provides a first possible implementation of the second aspect, wherein the disc is provided with a limiting groove along its circumferential direction, and the tail end of the engaging part of the locking pin body is fitted with both sides of the limiting groove.

[0012] In conjunction with the second aspect, this utility model provides a first possible implementation of the second aspect, wherein the side fin block of the engaging portion abuts against the edge of the groove.

[0013] Compared with the comparative technology, the beneficial effects of this utility model are: 1. The locking pin body of this utility model adopts an integrated structure, combining the plug part and the locking part into a single component, eliminating the need for separate mounting brackets and complex multi-component connections as described in the prior art. This integrated design not only simplifies the manufacturing process and reduces manufacturing costs, but more importantly, it avoids the risk of failure caused by the assembly of multiple components and fatigue of the elastic parts, significantly improving the structural strength and long-term reliability of the locking pin. The U-shaped slot design provides the necessary elasticity while making the structure more robust and durable.

[0014] 2. By directly pressing the squeezing block at the tail end of the locking part, the side fin locking block retracts using the lever principle (with the contact block as the fulcrum), achieving quick unlocking. This operation method is direct and labor-saving, and the space requirements are far less than the structure in the prior art that requires a specific pressing part and support part to cooperate. This allows this utility model to be easily assembled and disassembled even in confined spaces or in relatively hidden installation locations, greatly improving the practicality of the product and the user experience.

[0015] 3. The finned locking blocks on the locking pin body abut against the edge of the disc groove, providing radial clamping force; the plug part fits against the abutment block on the disc, and the tail end of the engaging part fits against both sides of the limiting groove, achieving precise axial and lateral positioning and limiting. This multi-point contact and cooperation ensures that the locking pin will not shake or loosen in the connected state, making the connection between the cylinder and the disc more stable and reliable, and ensuring the overall structural stability of the winding reel.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] This utility model provides a pin for use in a combined winding reel.

[0023] Reference Figures 1 to 2 As shown, in a first aspect, this utility model embodiment provides a locking pin, including a locking pin body 1. The locking pin body 1 includes a plug portion 2 and a locking portion 3. The locking portion 3 has a U-shaped slot 31 in the middle, side fin locking blocks 32 on both sides, and a pressing block 34 at the tail end. The U-shaped slot 31 is a key structure for achieving elasticity. Pressing the pressing block 34 forces the side fin locking blocks 32 to contract inward, causing elastic deformation of the U-shaped slot 31, providing movement space for the side fin locking blocks 34 on both sides. Compared with the multi-part assembly of the prior art, the integrated structure of this invention has better strength and stability, a direct unlocking method, and requires very little operating space. Moreover, the elastic deformation area of ​​the U-shaped slot 31 is large, and the stress distribution is more uniform. Compared with the concentrated "elastic part" in the prior art, it is less prone to breakage due to fatigue.

[0024] Furthermore, the U-shaped slot 31 is provided with two symmetrical contact blocks 33, which are close to the pressing block 34. When the pressing block 34 is pressed, the close contact blocks 33 form a stable lever fulcrum through the lever principle, so that the force can be converted into the contraction movement of the side fin block 32 more effectively and with less effort.

[0025] Furthermore, the upper end of the plug part 2 is provided with a ramp 21, which serves as an insertion guide. The inclined design of the ramp 21 makes the insertion process smooth and can naturally guide the locking pin body 1 into the groove.

[0026] Furthermore, a weight-reducing groove 22 is provided on the back of the plug part 2, and a reinforcing rib 23 is provided inside the weight-reducing groove 22. By setting the weight-reducing groove 22, the amount of material used is reduced, thereby achieving weight reduction. At the same time, the reinforcing rib 23 is provided inside the weight-reducing groove 22 to compensate for the strength loss that may be caused by weight reduction, ensuring that the plug part 2 has sufficient bending strength when subjected to insertion and extraction forces and lateral forces. Example

[0027] Reference Figures 3 to 6As shown, this embodiment of the utility model also provides an assembled winding reel, including a cylindrical body 4 and reels 5 disposed at both ends of the cylindrical body 4. The cylindrical body 4 has protrusions 41 at both ends, each protrusion 41 having a first slot 42. The reels 5 have a second slot 51 circumferentially along their center, and a groove 52 circumferentially along its center, each groove 52 having a through slot 53. The protrusions 41 and grooves 52 mate, and the first slot 42 aligns with the through slot 53 within the groove 52. The locking pin body 1 passes through the second slot 51 and the first slot 42 in sequence, connecting the cylindrical body 4 and the reels 5. The engagement of the protrusions 41 and grooves 52 achieves initial radial positioning of the cylindrical body 4 and the reels 5. The alignment of the first slot 42 with the second slot 51 and the through slot 53 provides an axial insertion channel for the locking pin body 1. After insertion, the locking pin body 1 passes through both the cylindrical body 4 and the reels 5, becoming a "detachable pin" connecting the two.

[0028] Furthermore, the disc 5 is provided with abutment blocks 54 along its circumferential direction. The top of the plug portion 2 of the locking pin body 1 fits against the abutment blocks 54 to form an axial stop, restricting the axial movement of the locking pin body 1 under the action of winding tension, and at the same time counteracting the relative axial force between the cylinder 4 and the disc 5. In addition, the abutment fit can serve as a visual basis for judging whether the locking pin body is installed in place, reducing the misinstallation rate.

[0029] Furthermore, the disc 5 is provided with a limiting groove 55 along its circumferential direction, and the tail end of the engaging part 3 of the locking pin body 1 is fitted with both sides of the limiting groove 55. This prevents the locking pin body 1 from moving within the hole. The limiting groove 55 and the abutment block 54 form a "axial-circumferential" double constraint on the locking pin body 1, improving the overall connection rigidity and ensuring that the side fin locking block 32 and the groove 52 are tightly engaged along the edge.

[0030] Furthermore, the side fin locking block 32 of the engaging part 3 abuts against the edge of the groove 52, which is the most fundamental locking method in this case. After the locking pin body 1 is inserted, its side fin locking block 32 rebounds under its own elasticity, forming an abutment interference with the edge of the groove 52, thereby locking the locking pin body 1 axially and preventing it from falling off. The mechanical locking provides a very reliable locking force, and it automatically locks after the locking pin body 1 is inserted, requiring no additional operation and simplifying the installation steps.
