Description

Technical Field

[0001] This utility model belongs to the technical field of conductive beam insulating protective sleeves, and in particular relates to conductive beam insulating protective sleeves for anodizing. Background Technology

[0002] The purpose of using an insulating protective sleeve on the conductive beam during the anodizing process is to ensure the correct distribution of current and to prevent electrochemical reactions or damage to the parts of the beam that come into contact with the oxidation solution.

[0003] In existing technologies, traditional insulating protective sleeves are mostly flat-fit type, with large gaps between them and the conductive beams. During the anodizing process, acidic electrolyte can easily seep in through the gaps, leading to beam corrosion and insulation layer failure, requiring frequent replacement of the protective sleeve. Therefore, we have proposed an insulating protective sleeve for conductive beams used in anodizing. Utility Model Content

[0004] The purpose of this invention is to provide an insulating protective sleeve for conductive crossbeams used in anodizing. By designing components such as the protruding block of the sealing structure, the annular sealing groove, and the acid-resistant elastic silicone ring, the problem of acidic electrolyte easily seeping into the assembly gap between the protective sleeve and the crossbeam in the prior art is solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an insulating protective sleeve for a conductive beam used in anodizing, including a conductive beam, a protective sleeve covering the outer periphery of the conductive beam, and a sealing structure inside the protective sleeve;

[0007] The sealing structure includes a protruding block, which is fixedly connected inside the protective sleeve. An annular sealing groove is formed inside the protruding block, and an acid-resistant elastic silicone ring is fixedly connected inside the annular sealing groove. A groove is formed inside the conductive beam to prevent acidic electrolyte from easily seeping in through the gaps during the anodizing process, which would lead to beam corrosion and insulation layer failure.

[0008] Furthermore, the number of protrusions, annular sealing grooves, and recesses is set to several, and they are symmetrical to each other along the vertical central axis of the conductive beam. The purpose is to form a labyrinthine sealing channel, which requires the electrolyte to flow around multiple times to penetrate, thus greatly extending the penetration path.

[0009] Furthermore, the compression of the acid-resistant elastic silicone ring is set to %, the purpose of which is to ensure that the fit does not fall off, while ensuring its sealing performance.

[0010] Furthermore, the size of the protrusion is equal to the size of the groove, the purpose of which is to ensure that the protrusion can be accurately inserted into the groove.

[0011] Furthermore, the protective sleeve has a three-layer composite structure inside, which consists of a protective wear-resistant layer, a structural reinforcement layer, and an insulating sealing layer from the outside to the inside. The purpose of this structure is to achieve long-term and reliable electrical insulation and physical protection in an electrolytic environment.

[0012] Furthermore, the material of the protective wear-resistant layer is set as polyvinylidene fluoride, and the thickness of the protective wear-resistant layer is set as 3-5mm. The purpose is to provide an effective protective layer by selecting polyvinylidene fluoride, a material with excellent corrosion resistance, wear resistance and high temperature resistance, so as to improve the wear resistance and chemical corrosion resistance of the equipment during long-term operation.

[0013] Furthermore, the structural reinforcement layer is made of carbon fiber, the insulating sealing layer is made of cross-linked polyethylene, and the thickness of the structural reinforcement layer is set to 2-5mm. The purpose is to reduce the overall weight and improve the durability and compressive strength of the equipment by selecting carbon fiber, a material with high strength, light weight and good tensile properties, while ensuring the strength and rigidity of the structure.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model utilizes the interplay between components such as the protruding blocks, annular sealing grooves, and acid-resistant elastic silicone rings in its sealing structure. During assembly, the protective sleeve is placed around the conductive crossbeam, with the protruding blocks inside precisely fitting into the grooves on the crossbeam surface. Simultaneously, the acid-resistant elastic silicone ring undergoes elastic deformation under 30% compression, forming a tight seal. Multiple protruding blocks and grooves are symmetrically distributed along the central axis, collectively constituting a labyrinthine sealing channel. This significantly extends the penetration path of the acidic electrolyte, greatly improves sealing reliability, effectively prevents crossbeam corrosion and insulation failure, and eliminates the need for frequent replacement of the protective sleeve.

[0016] 2. This utility model utilizes the cooperation between the protective wear-resistant layer and the structural reinforcement layer components of a three-layer composite structure. The protective sleeve adopts a three-layer composite structure: the outer layer is a polyvinylidene fluoride protective wear-resistant layer, which is corrosion-resistant and wear-resistant; the middle layer is a carbon fiber structural reinforcement layer, which provides high-strength support; and the inner layer is a cross-linked polyethylene insulating and sealing layer, which ensures reliable insulation. This structure has excellent chemical corrosion resistance, mechanical strength and electrical insulation performance, which significantly improves the durability and safety reliability of the protective sleeve in harsh electrolytic environments.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention is an insulating protective sleeve for a conductive beam used in anodizing, comprising a conductive beam 1, a protective sleeve 2 covering the outer periphery of the conductive beam 1, and a sealing structure 3 provided inside the protective sleeve 2;

[0028] The sealing structure 3 includes a protrusion 31, which is fixedly connected to the inside of the protective sleeve 2. An annular sealing groove 32 is provided inside the protrusion 31, and an acid-resistant elastic silicone ring 33 is fixedly connected inside the annular sealing groove 32. A groove 34 is provided inside the conductive beam 1. The purpose is to prevent acidic electrolyte from easily seeping in through the gaps during the anodizing process, which would cause the beam to corrode and the insulation layer to fail.

[0029] The number of protrusions 31, annular sealing grooves 32 and grooves 34 is set in several, and they are symmetrical to each other along the vertical central axis of the conductive beam 1. The purpose is to form a labyrinth-like sealing channel, which requires the electrolyte to flow around multiple times to penetrate, thus greatly extending the penetration path.

[0030] The compression of the acid-resistant elastic silicone ring 33 is set to 30% to ensure that it adheres properly and does not fall off, while also guaranteeing its sealing performance.

[0031] The size of the protrusion 31 is equal to the size of the groove 34, the purpose of which is to ensure that the protrusion 31 can be accurately inserted into the groove 34.

[0032] The protective sleeve 2 has a three-layer composite structure 4 inside. The three-layer composite structure 4 consists of a protective wear-resistant layer 41, a structural reinforcement layer 42, and an insulating sealing layer 43 from the outside to the inside. Its purpose is to achieve long-term and reliable electrical insulation and physical protection in an electrolytic environment.

[0033] The protective wear-resistant layer 41 is made of polyvinylidene fluoride and has a thickness of 3-5 mm. The purpose is to provide an effective protective layer by selecting polyvinylidene fluoride, a material with excellent corrosion resistance, wear resistance and high temperature resistance, so as to improve the wear resistance and chemical corrosion resistance of the equipment during long-term operation.

[0034] The structural reinforcement layer 42 is made of carbon fiber, and the insulating sealing layer 43 is made of cross-linked polyethylene. The thickness of the structural reinforcement layer 42 is 2-5mm. The purpose is to reduce the overall weight and improve the durability and compressive strength of the equipment by selecting carbon fiber, a material with high strength, light weight and good tensile properties, while ensuring the strength and rigidity of the structure.

[0035] One specific application of this embodiment is as follows: Before using the insulating protective sleeve 2, the acid-resistant elastic silicone ring 33 needs to be pre-installed in the annular sealing groove 32 inside the protective sleeve 2. During assembly, the protective sleeve 2 is placed around the conductive beam 1. The protrusions 31 inside the protective sleeve 2 and the grooves 34 on the surface of the conductive beam 1 are fitted one-to-one to form a precise positioning. During this process, the acid-resistant elastic silicone ring 33 is subjected to a 30% compression, producing appropriate elastic deformation and tightly fitting against the surface of the conductive beam 1 to achieve a primary seal. After the protective sleeve 2 is installed in place, the multiple protrusions 31, the annular sealing groove 32, and the grooves 34 are symmetrically arranged along the vertical central axis of the conductive beam 1. The fabric, together with the other components, forms a labyrinthine sealed channel. If acidic electrolyte attempts to penetrate through the assembly gaps, it must traverse this winding path, significantly extending the penetration distance and greatly increasing the penetration resistance. Meanwhile, the protective sleeve 2 itself adopts a three-layer composite structure 4 design: the outermost polyvinylidene fluoride protective wear-resistant layer 41 directly faces the electrolytic cell environment, resisting external chemical erosion and physical wear with its excellent corrosion resistance and wear resistance; the middle carbon fiber structure reinforcement layer 42 provides the necessary mechanical strength and dimensional stability for the whole, ensuring that the protective sleeve 2 does not deform during long-term use; and the inner cross-linked polyethylene insulating sealing layer 43 provides reliable electrical insulation protection.
