Description

Technical Field

[0001] This utility model relates to the field of steel coil packaging and protection technology, and in particular to a steel coil anti-rust and moisture-proof packaging structure. Background Technology

[0002] As an important semi-finished product in the steel production and processing industry, the surface quality of steel coils directly determines the performance of downstream products. During the transportation and storage of cold-rolled steel coils, it is necessary to prevent the ends of the steel coils from deforming due to collisions and squeezing, and to isolate them from external moisture and dust to prevent oxidation and rust on the surface of the steel coils. In particular, since cold-rolled steel coils do not have an oxide protective layer on their surface, the need for moisture and rust prevention is even more urgent. Therefore, the packaging structure of steel coils must have both protective and sealing functions.

[0003] For example, patent application CN219008626U in the prior art includes corner protector A and corner protector B. Corner protector A has insert rods fixedly connected to all four ends of its inner ring. Each insert rod has elastically connected locking blocks on both sides of its end away from corner protector A. Corner protector B has insert plates fixedly connected to all four ends of its inner ring for inserting the insert rods. Each insert plate has an array of slots on both sides for the locking blocks to engage. This solves the problem that during the installation of corner protectors for cold-rolled steel coils, workers often need to use ropes to thread through the corner protectors and tie them to the cold-rolled steel coils to ensure stability. This requires multiple tying operations, making the corner protector fixing process cumbersome and suitable for widespread promotion and use.

[0004] However, this device has two major flaws in practical applications: First, it lacks a sealing design for the end face of the steel coil. The end face of the steel coil has an annular opening structure, which allows moisture and rainwater to easily seep into the inside of the steel coil during transportation. After contacting the surface of the cold-rolled steel coil, it causes oxidation and rust, seriously affecting the quality of the steel coil. Second, the corner protector connection is not stable enough. The device fixes the corner protector by elastically engaging the insert rod and the insert plate. Since the structure of the engaging block and the position of the engaging groove are relatively fixed, it is difficult to flexibly adjust the connection tension according to the width of the steel coil. This results in the corner protector not fitting tightly to the end face of the steel coil. It is not only easy to loosen during transportation, but also further widens the gap at the end face, increasing the risk of moisture intrusion.

[0005] Therefore, it is necessary to provide a rust-proof and moisture-proof packaging structure for steel coils to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a rust-proof and moisture-proof packaging structure for steel coils, which solves the problems of existing steel coil packaging structures lacking end-face sealing design, insufficient corner protection connection stability, and inability to adapt to steel coils of different widths, resulting in easy moisture penetration and easy rusting of steel coils.

[0007] To solve the above-mentioned technical problems, this utility model provides a rust-proof and moisture-proof packaging structure for steel coils, comprising: First corner protector and second corner protector, both of which have support frames fixedly installed inside, and limit rings fixedly installed inside both support frames; Two waterproof sleeves are respectively fixedly installed on the inner sides of the first corner protector and the second corner protector; A connecting component is provided, which is respectively disposed on the inner side of the two limiting rings. One end of the connecting component is provided with a threaded rod, and the outer side of the threaded rod is threadedly connected with a threaded ring.

[0008] Preferably, each of the two limiting rings has a limiting groove at one end, and the other end of the connecting component is provided with a limiting member, which is engaged with the inner side of the limiting groove.

[0009] Preferably, a pad is fitted on the outer side of the threaded rod, and multiple rotating handles are fixedly installed on the side of the threaded ring.

[0010] Preferably, one side of the pad abuts against one end of one of the limiting rings.

[0011] Preferably, the connecting assembly includes a mounting rod, a sliding cavity, an extension rod, multiple positioning holes, positioning screws, and a connecting rod. The sliding cavity is formed inside the mounting rod, the extension rod is slidably connected to the inner side of the sliding cavity, the multiple positioning holes are respectively formed at the top and bottom of the extension rod, the positioning screws are respectively threaded into the inside of the top and bottom ends of the extension rod, and the connecting rod is fixedly installed at one end of the extension rod.

[0012] Preferably, the bottom of the positioning screw is engaged with the inner side of the positioning hole.

[0013] Preferably, the other end of the mounting rod is fixedly installed with the limiting member, and one end of the connecting rod is fixedly installed with the threaded rod.

[0014] Compared with related technologies, the rust-proof and moisture-proof packaging structure for steel coils provided by this utility model has the following beneficial effects: This utility model provides a rust-proof and moisture-proof packaging structure for steel coils. Through the coordinated operation of a first corner protector, a second corner protector, a support frame, a limiting ring, a waterproof sleeve, a connecting component, a threaded rod, and a threaded ring, the structure achieves two distinct functions. Firstly, the waterproof sleeves on the inner surfaces of the first and second corner protectors tightly adhere to both ends of the steel coil, forming a ring-shaped sealing barrier that directly prevents moisture and rainwater from seeping into the coil's end face, thus preventing rust. Secondly, the connecting component, in conjunction with the threaded rod, threaded ring, and pad, allows for flexible adjustment of the threaded ring's position by rotating the handle, ensuring the pad presses against the limiting ring. This, in turn, stably clamps the steel coil between the first and second corner protectors. This not only avoids the instability and loosening defects of existing elastic snap-fit ​​structures but also allows for the application of a uniform and controllable clamping force through thread adjustment, ensuring the waterproof sleeve remains tightly fitted to the steel coil's end face, further enhancing the sealing effect.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the first embodiment of a steel coil anti-rust and moisture-proof packaging structure provided by this utility model; Figure 2 for Figure 1The diagram shown is a schematic of the first corner protection structure. Figure 3 for Figure 2 The diagram shows another perspective of the structure; Figure 4 for Figure 1 The diagram shows the structure of the connection component.

[0019] A rust-proof and moisture-proof packaging structure for steel coils includes: a first corner protector 1 and a second corner protector 2, wherein a support frame 3 is fixedly installed inside the first corner protector 1 and the second corner protector 2, and a limit ring 4 is fixedly installed inside the two support frames 3; Two waterproof rubber sleeves 6 are respectively fixedly installed on the inner sides of the first corner protector 1 and the second corner protector 2; The connecting component 7 is respectively disposed on the inner side of the two limiting rings 4. One end of the connecting component 7 is provided with a threaded rod 9, and the outer side of the threaded rod 9 is threadedly connected with a threaded ring 11.

[0020] Each of the two limiting rings 4 has a limiting groove 5 at one end, and the other end of the connecting component 7 is provided with a limiting member 8, which is snapped into the inner side of the limiting groove 5.

[0021] A pad 10 is fitted on the outer side of the threaded rod 9, and multiple rotating handles 12 are fixedly installed on the side of the threaded ring 11.

[0022] One side of the pad 10 abuts against one end of the limiting ring 4.

[0023] The waterproof sleeve 6 is made of aging-resistant butyl rubber, which has good elasticity and strong sealing performance. The waterproof sleeve 6 forms a ring-shaped sealing barrier to prevent moisture and rainwater from seeping in from the end face of the steel coil. The support frame 3 and the limiting ring 4 inside the first corner protector 1 and the second corner protector 2 enhance the strength of the corner protector structure and prevent the ends of the steel coil from being deformed due to collision and squeezing during transportation. The connecting component 7 mates with the threaded rod 9, the threaded ring 11 and the pad 10 to ensure that the distance between the two corner protectors is fixed and to prevent the waterproof sleeve from loosening and causing the seal to fail. By using the limiting member 8 to lock onto the inner side of the limiting groove 5, the connecting component 7 and the threaded rod 9 can be limited between the first corner guard 1 during use, preventing the connecting component 7 and the threaded rod 9 from rotating when the user rotates the threaded ring 11.

[0024] The working principle of the rust-proof and moisture-proof packaging structure for steel coils provided by this utility model is as follows: After placing the steel coil horizontally, align the first corner protector 1 and the second corner protector 2 with the two ends of the steel coil respectively, so that the waterproof rubber sleeve 6 on the inner side of the corner protector fits the edge of the end face of the steel coil, ensuring that the waterproof rubber sleeve 6 completely covers the gap between the end face of the steel coil and the outside.

[0025] Insert the connecting component 7 into the inner side of the two limiting rings 4, and make the limiting piece 8 snap into the limiting groove 5 of the first corner protector 1 limiting ring 4, so that the connecting component 7 is stably connected to the first corner protector 1. Then put the pad 10 on the outer side of the threaded rod 9, and then screw on the threaded ring 11. By rotating the handle 12 on the side of the threaded ring 11, the threaded ring 11 is moved along the threaded rod 9 toward the second corner protector 2. The pad 10 moves with the threaded ring 11 and presses against the limiting ring 4 of the second corner protector 2. The handle 12 is rotated until the waterproof sleeves 6 of the first corner protector 1 and the second corner protector 2 are tightly attached to the end face of the steel coil, thus completing the sealing of both ends of the steel coil and the corner protector fixation.

[0026] Compared with related technologies, the rust-proof and moisture-proof packaging structure for steel coils provided by this utility model has the following beneficial effects: The components, including the first corner protector 1, the second corner protector 2, the support frame 3, the limiting ring 4, the waterproof sleeve 6, the connecting assembly 7, the threaded rod 9, and the threaded ring 11, work together to achieve the following: First, the waterproof sleeve 6 on the inner sides of the first corner protector 1 and the second corner protector 2 tightly adheres to both ends of the steel coil, forming a ring-shaped sealing barrier that directly prevents moisture and rainwater from seeping into the gaps at the end of the steel coil, thus preventing rust. Second, the connecting assembly 7, in conjunction with the threaded rod 9, the threaded ring 11, and the pad 10, allows for flexible adjustment of the position of the threaded ring 11 by rotating the handle 12, causing the pad 10 to press against the limiting ring 4. This ensures that the first corner protector 1 and the second corner protector 2 stably clamp the steel coil. This not only avoids the defects of unstable connection and easy loosening in existing elastic snap-fit ​​structures but also allows for the application of uniform and controllable clamping force through thread adjustment, ensuring that the waterproof sleeve 6 always tightly adheres to the end of the steel coil, further enhancing the sealing effect.

[0027] Second Embodiment Please refer to the following: Figure 5 Based on the rust-proof and moisture-proof packaging structure for steel coils provided in the first embodiment of this application, the second embodiment of this application proposes another rust-proof and moisture-proof packaging structure for steel coils. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0028] Specifically, the second embodiment of this application provides a steel coil rust-proof and moisture-proof packaging structure that differs in that the connecting component 7 includes an installation rod 71, a sliding cavity 72, an extension rod 73, multiple positioning holes 74, positioning screws 75, and a connecting rod 76. The sliding cavity 72 is opened inside the installation rod 71, the extension rod 73 is slidably connected to the inner side of the sliding cavity 72, the multiple positioning holes 74 are respectively opened at the top and bottom of the extension rod 73, the positioning screws 75 are respectively threaded to the inside of the top and bottom ends of the extension rod 73, and the connecting rod 76 is fixedly installed at one end of the extension rod 73.

[0029] The bottom of the positioning screw 75 is engaged with the inner side of the positioning hole 74.

[0030] The other end of the mounting rod 71 is fixedly installed with the limiting member 8, and one end of the connecting rod 76 is fixedly installed with the threaded rod 9.

[0031] Positioning holes 74 are evenly distributed along the length of extension rod 73 to ensure length adjustment accuracy and adapt to steel coils of different specifications.

[0032] The working principle of the rust-proof and moisture-proof packaging structure for steel coils provided by this utility model is as follows: According to the actual width of the steel coil, adjust the length of the connecting component 7. First, loosen the positioning screws 75 at the top and bottom of the mounting rod 71 so that the bottom of the positioning screws 75 disengages from the positioning hole 74 of the extension rod 73, thereby releasing the lock between the extension rod and the mounting rod. Pull the extension rod 73 to slide along the sliding cavity 72 of the mounting rod 71 to adjust the overall length of the connecting component 7 to match the width of the steel coil. After the length is adjusted to the correct position, tighten the positioning screw 75 so that the bottom of the positioning screw 75 is engaged in the positioning hole 74 at the corresponding position of the extension rod 73, lock the position of the extension rod 73, and complete the length adjustment of the connecting component 7. Then, following the operating procedure of the first embodiment, the connecting component 7 is engaged with the threaded rod 9 and the threaded ring 11 to complete the sealing of the steel coil packaging.

[0033] Compared with related technologies, the rust-proof and moisture-proof packaging structure for steel coils provided by this utility model has the following beneficial effects: By setting the connecting component 7, when limiting the distance between the first corner protector 1 and the second corner protector 2, the length of the connecting component 7 can be adjusted to be slightly longer than the distance between the two limiting rings 4. Then, the threaded rod 9 and the threaded ring 11 cooperate to limit the distance between the two corner protectors. In this way, the user does not need to rotate the threaded ring 11 for a long time to make the threaded ring 11 threadedly connected to the outer side of the threaded rod 9, which drives the two corner protectors to move towards the middle, thereby increasing the efficiency of limiting the distance between the two corner protectors.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
