Abstract
Description
Technical Field
[0001] This application relates to the field of flexible support technology, and more particularly to a lifting ring. Background Technology
[0002] Lifting rings, as common connecting and supporting components, play a vital role in lifting operations. However, many lifting ring products on the market are insufficient in terms of corrosion resistance and wear resistance, which directly affects their service life and lifting performance.
[0003] For example, during use, lifting rings are prone to frequent friction and collisions with cables or other objects, leading to surface wear and localized damage, which in turn affects their service life and lifting performance. Furthermore, due to the insufficient corrosion and wear resistance of lifting rings, frequent inspection and maintenance are necessary to prevent potential problems from going undetected and developing into serious damage.
[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content
[0005] The purpose of this application is to provide a lifting ring with good properties such as corrosion resistance and wear resistance, which can be widely used in flexible supports and requires virtually no maintenance.
[0006] The technical solution provided by this utility model is as follows:
[0007] A hanging ring, comprising:
[0008] A lifting component, wherein the lifting component is provided with lifting holes for lifting linear items;
[0009] A connector, comprising a head end and a rod portion, the head end being fixedly connected to the lifting component, and the rod portion being used to dock with an external structure to fix the linear item lifted by the lifting component to the external structure; a covering component, comprising a first covering portion and a second covering portion, the first covering portion covering the lifting component, and the second covering portion at least partially covering the head end.
[0010] In some embodiments, the covering is made of a polymer material.
[0011] In some embodiments, the covering is integrally injection molded onto the surfaces of the lifting component and the connecting component.
[0012] In some embodiments, the first covering portion has a sloped surface formed on the wall of the hoisting hole.
[0013] In some embodiments, the angle between the slope extension direction and the axial direction of the hoisting hole is 3°-5°.
[0014] In some embodiments, the second covering portion near one end of the first covering portion has arc-shaped surfaces formed on both sides of the hoisting hole along the axial direction, and the arc-shaped surfaces have a slope.
[0015] In some embodiments, the arc length angle of the arcuate surface ranges from 23° to 45°.
[0016] In some embodiments, the connector is a screw having the head end, which is connected to the lifting member and covered within the second covering portion.
[0017] In some embodiments, the second covering portion completely covers the head end.
[0018] In some embodiments, the head end is fixed to the lifting component by welding;
[0019] or,
[0020] The lifting component is provided with a connecting part, the connecting part is provided with an external thread, and the head end is provided with a threaded hole. The external thread and the threaded hole are threadedly engaged to realize the connection between the head end and the lifting component.
[0021] This application has at least one of the following technical effects:
[0022] 1. In this application, the covering element encloses the lifting component and at least part of the connecting component, effectively protecting the lifting ring's lifting parts. During use, this not only increases the tensile strength but also reduces friction, improving the lifting ring's wear and corrosion resistance. Simultaneously, the covering element covers the connection between the lifting component and the connecting component, thereby increasing the connection strength and allowing the lifting ring to withstand greater tensile forces. This application achieves excellent corrosion and wear resistance in the lifting ring simply by incorporating the covering element; the overall structure is simple and cost-effective. Furthermore, due to the presence of the covering element, the lifting ring disclosed in this application requires virtually no maintenance, has a long inspection cycle, and low maintenance costs, making it widely applicable to flexible supports.
[0023] 2. In this application, the covering is made of a polymer material, which has high wear resistance and corrosion resistance, thus improving the service life of the lifting ring and enabling it to be better applied to flexible supports. At the same time, the polymer material covering is also lighter, facilitating lightweight production. The covering in this application is integrally injection molded onto the surface of the lifting and connecting parts, making processing convenient and cost-effective.
[0024] 3. In this application, the first covering portion has a sloping surface on the wall of the lifting hole, which facilitates the removal of the covered part from the mold after injection molding. It also increases the fluidity of the polymer liquid material in the injection molding machine, allowing the polymer material to maintain a more uniform thickness, thereby achieving better encapsulation. The second covering portion has a sloping arc-shaped surface on both sides of the lifting hole axially near the end of the first covering portion. This also increases the convenience of demolding and the fluidity of the polymer liquid material in the injection molding machine, which is more conducive to the molding of the covered part.
[0025] 4. In this application, the connecting parts are made of screws, which makes disassembly and assembly more convenient. At the same time, the head of the screw is completely enclosed in the cover. The injection-molded cover can limit the head of the screw, thereby preventing the screw and the lifting parts from coming out of the cover, resulting in a longer service life.

[0034] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details.

Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0036] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled.

[0037] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.
[0038] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0039] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, these directional indications also change accordingly.
[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0041] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figures 1 to 4 A lifting ring 100 is disclosed, including a lifting component 110 and a connecting component 120 connected together. The lifting component 110 has a lifting hole 111 for lifting linear items. The connecting component 120 includes a head end 121 and a rod portion 122. The head end is fixedly connected to the lifting component, and the rod portion is used to dock with an external structure to fix the linear item lifted by the lifting component to the external structure.
[0042] As a common connecting and supporting component, the lifting ring 100 has a lifting hole 111 that can be used to connect to the items to be lifted, such as cables and wires. By connecting the lifting ring 100 to the external structure through the connector 120, the weight of the items can be transferred to the external structure, thereby realizing the lifting and fixing of the items.
[0043] Flexible supports possess high flexibility and plasticity, allowing them to be bent and installed according to various curved shapes, making them ideal for installation on curved or unconventional curved surfaces. The lifting rings 100, serving as both connecting and supporting components, can adapt to this flexibility requirement, allowing the flexible supports to be adjusted and secured in different terrains and environments. Because flexible supports need to be exposed to the outdoors for extended periods, the lifting rings 100 used in them will also be subject to long-term environmental influences.
[0044] To improve the corrosion resistance and wear resistance of the lifting eyelet 100, see [reference needed]. Figures 1 to 3 In a preferred embodiment, the surfaces of the connected lifting member 110 and connecting member 120 are further covered by a covering member 130. The covering member 130 includes a first covering portion 131 and a second covering portion 132. The first covering portion 131 covers the lifting member 110, and the shape of the first covering portion 131 matches the shape of the lifting member 110. The second covering portion 132 at least covers a portion of the head end 121. The second covering portion 132 at least covers a portion of the head end 121, meaning that the second covering portion 132 can cover a portion of the head end 121 or completely cover the head end 121. In this embodiment, the head end 121 is completely covered within the second covering portion 132, thereby ensuring a good connection between the covering member 130 and the lifting member 110 and connecting member 120.
[0045] In this embodiment, the covering 130 covers the lifting component 110 and at least part of the connecting component 120, which can effectively protect the lifting part of the lifting ring 100 used for lifting. During use, it not only improves the tensile strength but also reduces friction, which is beneficial to improving the wear resistance and corrosion resistance of the lifting ring 100. At the same time, the covering 130 can cover the connection between the lifting component 110 and the connecting component 120, thereby improving the connection strength between the lifting component 110 and the connecting component 120, so that the lifting ring 100 can withstand greater tensile force.
[0046] This embodiment provides the lifting ring 100 with excellent properties such as corrosion resistance and wear resistance by setting the covering component 130. The overall structure is simple and low in cost. In addition, due to the presence of the covering component 130, the lifting ring 100 disclosed in this embodiment requires virtually no maintenance, has a long inspection cycle, and low maintenance cost, making it widely applicable to flexible supports.
[0047] The covering component 130 is preferably made of a polymer material, which has better wear resistance and corrosion resistance, thus extending the service life of the lifting ring 100 and enabling it to be better applied to flexible supports. At the same time, the covering component 130 made of polymer material is also lighter, which is beneficial for lightweight production.
[0048] Furthermore, the covering 130 adopts an integral injection molding process, directly forming it on the surface of the lifting component 110 and the connecting component 120, resulting in higher structural strength, easier processing, and lower cost.
[0049] In one example embodiment, the lifting component 110 and the connecting component 120 are preferably fixed by welding, which provides a strong connection between them. After the lifting component 110 and the connecting component 120 are welded together, they are placed in a mold for injection molding, and finally demolded to obtain the desired lifting ring 100.
[0050] Of course, in actual production, other connection methods can be used between the lifting component 110 and the connecting component 120. For example, the lifting component 110 and the connecting component 120 can be connected by a threaded structure.
[0051] Specifically, the lifting component 110 is provided with a connecting part, which has an external thread 201. The connecting component 120 has a threaded hole, and the connecting part and the threaded hole are threadedly engaged, thereby achieving a fixed connection between the connecting component 120 and the lifting component 110. After the lifting component 110 and the connecting component 120 are fixed, the entire connection is placed into a mold for injection molding, and finally demolded to obtain the required lifting ring 100. No further limitations are imposed here, all of which are within the scope of protection of this application.
[0052] In one specific embodiment, see Figure 1 and Figure 4 The lifting component 110 has a circular structure, which requires less production material for the same size lifting hole 111, further saving production costs. The connector 120 includes screws for connecting to the external structure. After the screws pass through the bolt holes on the external structure, they are tightened with nuts, thereby fixing the lifted items to the external structure, making assembly and disassembly more convenient.
[0053] Specifically, countersunk screws are used, which facilitates a more stable connection with the lifting component 110. The screw has a head end 121, which connects to the lifting component 110 and is completely enclosed within a second covering portion 132. This allows the covering portion 130 to better engage with the lifting component 110 and the connecting component 120, preventing the covering portion 130 from detaching from the outside of the lifting component 110 and the connecting component 120. If the screw and the lifting component 110 are fixed by welding, the head end 121 of the screw is welded to the lifting component 110; if the screw and the lifting component 110 are connected by threaded tightening, a threaded hole can be made in the head end 121 to mate with the connecting portion on the lifting component 110.
[0054] Specifically, see Figure 3 and Figure 4 The screw also includes a shank 122 located on the side of the head end 121 away from the lifting member 110. The shank 122 is provided with external threads 201 to form a threaded structure. The lifting ring can be fixed by passing the shank 122 through the bolt hole on the external structure and tightening it with a nut, thereby fixing the item.
[0055] In this embodiment, see Figure 3 The head 121 of the screw is completely enclosed in the cover 130, so that the injection-molded cover 130 can limit the head 121 of the screw, thereby preventing the screw and the lifting part 110 from coming out of the cover 130, which helps to increase the service life of the lifting ring 100.
[0056] Preferably, the end of the second covering portion 132 that is away from the first covering portion 131 is flush with the end of the head end 121 that is away from the lifting member 110.
[0057] Furthermore, the first covering part 131 has a slope 1311 formed on the wall of the lifting hole 111. On the one hand, it can facilitate the removal of the covering part 130 from the mold after molding. On the other hand, it can increase the fluidity of the polymer liquid material in the injection molding machine, so that the polymer material maintains a relatively uniform thickness, thereby achieving better wrapping.
[0058] The angle formed by the extension direction of the slope 1311 and the axial direction of the hoisting hole 111 is preferably 3°-5°.
[0059] Furthermore, see Figures 1 to 3 The second covering part 132 is close to one end of the first covering part 131, and has arc-shaped surfaces 1321 formed on both sides of the lifting hole 111 in the axial direction. The arc-shaped surfaces 1321 have a slope, which can also increase the convenience of demolding. At the same time, it increases the fluidity of the polymer liquid material in the injection molding machine, so that the polymer material maintains a relatively uniform thickness, thereby achieving better wrapping and making it more conducive to the molding of the covering part 130.
[0060] In this embodiment, the arc length angle range of the arc surface 1321 is preferably 23°-45°.
[0061] This application utilizes polymer materials to injection mold and coat the pre-processed lifting ring 100 (i.e., the already fixedly connected lifting component 110 and connector 120), giving the lifting ring 100 high wear resistance and high corrosion resistance. High wear resistance reduces wear caused by friction and collision with cables and other conduits, while high corrosion resistance allows it to better adapt to the natural environment and mitigate the impact of external weather (e.g., humidity, rain) on the lifting ring 100, thereby effectively extending its service life. It requires virtually no maintenance, is simple to maintain, and has low maintenance costs.
[0062] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0063] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
