Description

Technical Field

[0001] This utility model relates to the field of insulating sleeve technology, specifically to an insulating sleeve with a rotary sealing structure. Background Technology

[0002] In the operating environment of electrical equipment and electronic systems, insulating sleeves play a crucial role as a key protective component. Insulating sleeves are primarily used to wrap wires, cables, or other electrical components. Their core functions are to isolate current, prevent leakage, and resist the corrosive effects of external environmental factors (such as dust, moisture, and chemicals) on electrical components, thereby ensuring the safe and stable operation of the electrical system. As modern electrical equipment and electronic systems develop towards higher integration and higher power density, the performance requirements for insulating sleeves are becoming increasingly stringent. They not only need excellent insulation performance and protective capabilities but also need to meet the requirements of convenient installation and reliable sealing under different operating conditions. Therefore, developing an efficient and reliable insulating sleeve sealing structure has become an important issue that urgently needs to be addressed in the industry.

[0003] Traditional sealing techniques for insulating sleeves primarily employ snap-fit ​​connections or adhesive bonding. While snap-fit ​​connections offer convenient installation, their sealing performance is often limited by material elasticity and manufacturing processes, making it difficult to maintain a stable seal over long-term use. Adhesive bonding suffers from long curing times, poor temperature resistance, and the adhesive areas are often difficult to clean during disassembly and maintenance, easily leading to secondary damage. These drawbacks of traditional sealing techniques not only affect the performance and lifespan of insulating sleeves but also increase equipment maintenance costs and downtime, posing a potential threat to the safe and stable operation of electrical equipment and electronic systems. Therefore, developing a novel rotary-sealing structure for insulating sleeves has significant practical importance and application value. To this end, we propose a rotary-sealing structure for insulating sleeves. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an insulating sleeve with a rotary sealing structure, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: an insulating tube sleeve with a rotary sealing structure, comprising an insulating tube, a connecting ring provided on the inner wall of one end of the insulating tube, two equidistantly distributed annular limiting grooves provided on the outer wall of the end of the connecting ring away from the insulating tube, and two equidistantly distributed limiting locking slides provided on the inner wall of the end of the connecting ring near the limiting grooves, the limiting locking slides communicating with the limiting grooves.

[0006] Preferably, the insulating tube is provided with a sealing cap at one end near the connecting ring. One end of the inner wall of the sealing cap is inserted into the connecting ring. The inner wall of the sealing cap at one end near the connecting ring is provided with two limiting blocks that are distributed in a ring at equal intervals. The limiting blocks are in clearance fit with the limiting groove. The outer wall of one end of the limiting groove is in sliding fit with the inner wall of the limiting locking slide.

[0007] Preferably, the outer wall of the sealing cap has four locking slots that are equidistantly distributed in a ring, and the outer wall of one end of the insulating tube has four second locking slots that are equidistantly distributed in a ring, with the second locking slots being parallel to the locking slots.

[0008] Preferably, locking pieces are movably connected to both ends of the inner wall of the locking piece groove, with the bottom surface of one end of the locking piece contacting the bottom of the inner wall of the locking piece groove, and the bottom surface of the locking piece near the locking piece groove contacting the bottom of the inner wall of the second locking piece groove.

[0009] Preferably, the outer wall of the locking piece has two locking holes that are equidistantly distributed laterally, and the outer wall of the insulating tube near the second locking piece groove has two threaded holes that are equidistantly distributed laterally. The threaded holes are arranged in four sets in a ring on the outer wall of the insulating tube.

[0010] Compared with the prior art, this utility model provides an insulating sleeve with a rotary sealing structure, which has the following advantages:

[0011] 1. Compared to traditional insulating sleeve sealing technologies, such as snap-fit ​​connections where sealing stability is limited by material elasticity, this rotating sealing structure significantly improves operational convenience. In this device, the sealing cap and connecting ring achieve initial positioning and stable connection through the ingenious cooperation of limiting blocks, limiting grooves, and limiting locking slides. Operators simply rotate the sealing cap to move the locking piece to the appropriate position under the guidance of the locking piece groove and the second locking piece groove, and then complete the fixation through the threaded connection of screws and threaded holes. The entire process requires no complex tools and can be completed by hand, greatly saving installation and disassembly time. In emergency situations such as power outages and equipment maintenance, this convenient operation method can quickly complete the installation and disassembly of insulating sleeves, improving work efficiency, reducing equipment downtime, and providing strong support for the rapid restoration of electrical system operation.

[0012] 2. Compared to traditional insulating sleeve sealing technologies, this rotary sealing structure often struggles to maintain good sealing performance and stability during long-term use. Adhesive bonding methods suffer from poor temperature resistance and are difficult to disassemble, easily leading to secondary damage. However, the rotary sealing structure of this device effectively solves these problems through the synergistic action of multiple components. The cooperation between the limiting groove and the limiting locking slide ensures the initial axial positioning stability of the sealing cap and connecting ring. The cooperation between the locking plate and the locking plate groove, the second locking plate groove, and the screw and threaded hole further enhances the connection strength between the sealing cap and the insulating tube, forming a reliable sealing structure. This multi-layered fixing and sealing design enables the device to maintain stable sealing performance during long-term use, effectively preventing the intrusion of external factors such as dust and moisture, improving the insulating sleeve's protection capability for electrical components, and extending the service life of the equipment.

[0013] 3. Compared to traditional insulating tube sealing technologies, which often damage components during disassembly and repair, leading to unusability and increased maintenance costs, this rotary sealing structure offers superior reusability. For example, adhesive-based sealing methods are difficult to clean after disassembly, often resulting in the tube being scrapped. The components are detachably connected, such as screws to threaded holes. Disassembly simply involves unscrewing the screws to easily separate the sealing cap from the insulating tube without damaging the components. When reuse is needed, the sealing cap is simply reinserted into the connecting ring, rotated to the appropriate position, and the screws tightened. This reusability significantly reduces maintenance costs and resource waste. Furthermore, the simple design and easy replacement and repair of components further reduce maintenance difficulty and costs, bringing significant economic benefits to users.

[0018] 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.

[0019] Please see Figure 1-3 An insulating sleeve with a rotary sealing structure includes an insulating tube 1. A connecting ring 2 is provided on the inner wall of one end of the insulating tube 1. Two equidistant annular limiting grooves 3 are provided on the outer wall of the end of the connecting ring 2 away from the insulating tube 1. Two equidistant annular limiting locking slides 4 are provided on the inner wall of the end of the connecting ring 2 close to the limiting grooves 3. The limiting locking slides 4 communicate with the limiting grooves 3. The design of the limiting grooves 3 and the limiting locking slides 4 provides a basic structure for the subsequent installation and positioning of the sealing cap 5, so that the sealing cap 5 can be installed according to a specific path, ensuring the accuracy and stability of the installation.

[0020] Furthermore, the insulating tube 1 has a sealing cap 5 near the connecting ring 2. One end of the inner wall of the sealing cap 5 is inserted into the connecting ring 2. The inner wall of the sealing cap 5 near the connecting ring 2 has two equidistant ring-shaped limiting blocks 6. The limiting blocks 6 are in clearance fit with the limiting groove 3. The outer wall of one end of the limiting groove 3 is in sliding fit with the inner wall of the limiting locking slide 4. The insertion fit between the sealing cap 5 and the connecting ring 2, the clearance fit between the limiting blocks 6 and the limiting groove 3, and the sliding fit between the outer wall of the limiting groove 3 and the inner wall of the limiting locking slide 4 allow the sealing cap 5 to be smoothly inserted into the connecting ring 2. During the insertion process, the sliding of the limiting blocks 6 within the limiting locking slide 4 achieves the initial positioning and stable connection between the sealing cap 5 and the connecting ring 2, preventing the sealing cap 5 from shifting or shaking during installation.

[0021] Furthermore, the outer wall of the sealing cap 5 is provided with four locking slots 7 arranged in a ring at equal intervals, and the outer wall of one end of the insulating tube 1 is provided with four second locking slots 8 arranged in a ring at equal intervals. The second locking slots 8 are parallel to the locking slots 7. The parallel arrangement of the locking slots 7 and the second locking slots 8 provides space for the installation and movement of the locking piece 9, allowing the locking piece 9 to slide freely between the locking slots 7 and the second locking slots 8. This provides a structural basis for further fixing of the sealing cap 5 and the insulating tube 1 by the locking piece 9.

[0022] Furthermore, locking pieces 9 are movably connected to both ends of the inner wall of the locking piece groove 7. The bottom surface of one end of the locking piece 9 contacts the bottom of the inner wall of the locking piece groove 7, and the bottom surface of the locking piece 9 near the locking piece groove 7 contacts the bottom of the inner wall of the second locking piece groove 8. The movable connection of the locking piece 9 within the locking piece groove 7 and the second locking piece groove 8 allows the locking piece 9 to be adjusted in position as needed. When it is necessary to fix the sealing cover 5, the locking piece 9 can move to a suitable position under the guidance of the locking piece groove 7 and the second locking piece groove 8, thereby achieving a firm connection between the sealing cover 5 and the insulating tube 1. When it is necessary to disassemble, the locking piece 9 can be easily moved to release the fixation between the sealing cover 5 and the insulating tube 1.

[0023] Furthermore, two locking holes 10 are provided on one side of the outer wall of the locking piece 9, which are distributed horizontally at equal intervals. Two threaded holes 11 are provided on the outer wall of the insulating tube 1 near the second locking piece groove 8, which are distributed horizontally at equal intervals. There are four sets of threaded holes 11 distributed in a ring on the outer wall of the insulating tube 1. The setting of the locking holes 10 and the threaded holes 11 provides a position for the installation of the screw 12. By passing the screw 12 through the locking holes 10 and connecting it with the threaded holes 11, the locking piece 9 can be firmly fixed on the insulating tube 1, thereby further enhancing the connection strength between the sealing cap 5 and the insulating tube 1 and ensuring the sealing and stability of the insulating tube sleeve during use.

[0024] Furthermore, the output end of the locking hole 10 is provided with a screw 12, and the output end of the screw 12 is threadedly connected to the inner wall of the threaded hole 11. The threaded connection between the screw 12 and the threaded hole 11 allows the locking piece 9 to be tightly fixed on the insulating tube 1, preventing the locking piece 9 from loosening or falling off during use, ensuring that the connection between the sealing cap 5 and the insulating tube 1 is firm and reliable, and improving the overall performance and service life of the insulating tube sleeve.

[0025] Furthermore, the outer wall of the sealing cap 5 is provided with several anti-slip grooves 13 distributed in an annular pattern. The anti-slip grooves 13 increase the friction between the operator's hand and the sealing cap 5, making it more convenient and effortless to install or remove the sealing cap 5 by rotating it. This avoids the situation where the operator's hand slips, which may cause difficulties in operation or damage to the insulating sleeve, and improves the convenience and safety of operation.

[0040] Working principle: First, during assembly, the sealing cap 5 is inserted into the connecting ring 2 at one end of the insulating tube 1. At this time, the limiting block 6 on the inner wall of the sealing cap 5 and the limiting groove 3 on the outer wall of the connecting ring 2 form a clearance fit (the limiting block 6 and the limiting groove 3 are in clearance fit). As the sealing cap 5 is continuously inserted, the limiting block 6 slides along the limiting locking slide 4 (the outer wall of one end of the limiting groove 3 and the inner wall of the limiting locking slide 4 are in sliding fit) until the limiting block 6 is completely inserted into the limiting groove 3, realizing the initial axial positioning of the sealing cap 5 and the connecting ring 2, ensuring the stability of the sealing cap 5 and the insulating tube 1 during connection, and preventing them from easily falling off. Then, after the sealing cap 5 and the insulating tube 1 have completed the initial connection, the locking piece 9 is used to lock them in place to further secure them. The locking piece 9 is movably connected to both ends of the inner wall of the locking piece groove 7 on the outer wall of the sealing cap 5 (the two ends of the inner wall of the locking piece groove 7 are movably connected to the locking piece 9), and the bottom surface of one end of the locking piece 9 contacts the bottom of the inner wall of the locking piece groove 7, and the bottom surface of the other end contacts the bottom of the inner wall of the second locking piece groove 8 on the outer wall of the insulating tube 1 (the bottom surface of the locking piece 9 near the locking piece groove 7 contacts the bottom of the inner wall of the second locking piece groove 8). At this time, by rotating the sealing cap 5, the locking piece 9 changes position under the guidance of the locking piece groove 7 and the second locking piece groove 8. When rotated to the appropriate position, the locking hole 10 on the locking piece 9 is aligned with the threaded hole 11 on the outer wall of the insulating tube 1. Finally, the screw 12 is passed through the locking hole 10 and threadedly connected to the threaded hole 11 (the output end of the locking hole 10 is provided with the screw 12, and the output end of the screw 12 is threadedly connected to the inner wall of the threaded hole 11), thereby fixing the locking piece 9 to the insulating tube 1, further enhancing the connection strength between the sealing cap 5 and the insulating tube 1, and achieving a stable sealing effect. Meanwhile, the anti-slip grooves 13 on the outer wall of the sealing cap 5 (several anti-slip grooves 13 are provided on the outer wall of the sealing cap 5 in a ring-shaped and equidistant manner) facilitate the operator's rotation of the sealing cap 5, making the entire operation process more convenient. When disassembly is required, simply unscrew the screws 12, rotate the sealing cap 5 in the opposite direction to disengage the locking piece 9 from the threaded hole 11, and then pull the sealing cap 5 out of the connecting ring 2.
