[0004] Existing traditional insulating bushings are cumbersome to install and remove during use, requiring specialized tools to disassemble each component individually. This is especially time-consuming in high-voltage scenarios, impacting power supply efficiency. Furthermore, when dealing with curved lines in wiring scenarios, existing insulating bushings cannot effectively increase the insulation distance at the bend. Under high-voltage conditions, the curved sections of the line are prone to breakdown due to insufficient insulation, greatly threatening the stable operation of the power system.

[0005] Therefore, a quick-assembly and disassembly split insulating sleeve is proposed to address the above problems. Utility Model Content

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5As shown, this utility model provides a quick-release, detachable, split-type insulating sleeve, including an outer sleeve 1. A bending insulation component 2 is installed at the top of the outer sleeve 1. An inner sleeve 3 and an inner sleeve 4 are provided on the inner surface of the outer sleeve 1. Threads are engraved on the outer surfaces of the outer sleeve 1, inner sleeve 3, and inner sleeve 4. The inner sleeve 3 and inner sleeve 4 are threaded together and threadedly connected to the outer sleeve 1. Two rectangular grooves 42 are provided at the end of the inner sleeve 4 that fits against the inner sleeve 3. Mounting plates 427 are installed on the inner surfaces of the two rectangular grooves 42. Two sleeve rods 425 are fixedly connected to one end of each mounting plate 427. Each sleeve rod 425 has a spring 422 fixedly connected to one side of its inner wall. Each of the four springs 422 has a snap-fit ​​block 423 fixedly connected to one end. The outer surfaces of the two corresponding snap-fit ​​blocks 423 are provided with a spherical block 31. The outer surfaces of the two spherical blocks 31 are provided with grooves 424 that are used to cooperate with the two snap-fit ​​blocks 423. The two spherical blocks 31 are fixedly connected to the inner sleeve 3. Through the cooperation of the springs 422, snap-fit ​​blocks 423, spherical blocks 31 and other structures, the inner sleeve 3 and the inner sleeve 4 can be quickly snapped and fixed. Installation can be completed without complicated tools, which greatly improves the efficiency of disassembly and assembly of the insulating sleeve.

[0028] Specifically, one end of the inner sleeve 2 4 is provided with four positioning grooves 43, and one end of the inner sleeve 1 3 is fixedly connected with a positioning block 32 that works with the four positioning grooves 43. The cooperation between the positioning block 32 and the positioning grooves 43 provides precise positioning for the docking of the inner sleeve 1 3 and the inner sleeve 2 4, ensuring the coaxiality of the internal conductive rod 9 installation, avoiding poor contact due to misalignment, and improving connection stability.

[0029] like Figures 1 to 5 As shown, the inner surfaces of the outer sleeve 1, inner sleeve 1 3 and inner sleeve 2 4 are all provided with circular grooves 41, and the inner surfaces of the three circular grooves 41 are provided with conductive rods 9. The top of the conductive rods 9 is fixedly connected with wires 5.

[0030] Furthermore, each of the four snap-fit ​​blocks 423 has two guide blocks 426 fixedly connected to its outer surface, and each of the four sleeve rods 425 has a guide groove 421 fixedly connected to its inner surface to cooperate with the two guide blocks 426. The cooperation between the guide blocks 426 and the guide grooves 421 provides guidance for the movement of the snap-fit ​​blocks 423, making the inner sleeve 1 3 and inner sleeve 2 4 more smoothly connected during the docking process, further improving the installation efficiency, and at the same time preventing the snap-fit ​​blocks 423 from shifting and affecting the snap-fit ​​effect.

[0031] It is worth emphasizing that the upper inner wall of the outer sleeve 1 is provided with a sealing gasket 6, which fits in close with the inner sleeve 3 and the inner sleeve 4. The sealing gasket 6 effectively prevents external dust, moisture and other impurities from entering the sleeve, protecting the inner sleeve 3, the inner sleeve 4 and the internal circuitry, and extending the service life of the insulating sleeve.

[0032] like Figures 1 to 5 As shown, the bending insulation assembly 2 includes three protruding plates 8, with two adjacent protruding plates 8 fixedly connected to each other. The design of the three protruding plates 8 in the bending insulation assembly 2 increases the insulation distance and insulation material coverage area at the bending point of the line, significantly improving the insulation performance of the bending part of the line and reducing the risk of high voltage breakdown.

[0033] It is worth noting that the outer surface of the outer sleeve 1 is provided with several annular protrusions 7. The annular protrusions 7 increase the creepage distance of the outer sleeve 1, further improving the overall insulation performance of the insulating sleeve and enhancing the operational reliability of the equipment in complex electrical environments.

[0034] Working principle and process: During installation, first fix the wire 5 to the top of the conductive rod 9, then place the conductive rod 9 in the circular groove 41 on the inner surface of the outer sleeve 1, inner sleeve 1 3 and inner sleeve 2 4. Align the positioning block 32 of inner sleeve 1 3 with the positioning groove 43 of inner sleeve 2 4 and insert it. At the same time, the spherical block 31 of inner sleeve 1 3 enters the rectangular groove 42 of inner sleeve 2 4. The guide block 426 slides along the guide groove 421 to make the snap-fit ​​block 423 accurately aligned. The spring 422 pushes the snap-fit ​​block 423 into the groove 424 of the spherical block 31, realizing the initial snap-fit ​​between inner sleeve 1 3 and inner sleeve 2 4. Finally, the outer sleeve 1 is screwed onto the inner sleeve 3 and inner sleeve 4 by threading. During the process, the sealing gasket 6 is compressed and fits tightly against the inner sleeve to achieve a seal. When there is a bend in the line, the protruding plate 8 of the bend insulation component 2 provides additional insulation protection at the bend. The annular protrusion 7 on the outer surface of the outer sleeve 1 ensures insulation performance by increasing the creepage distance. During disassembly, the outer sleeve 1 is loosened by unscrewing in the opposite direction, which overcomes the elastic force of the spring 422 to separate the snap-fit ​​block 423 from the spherical block 31, allowing for quick disassembly of the inner sleeve 3 and inner sleeve 4 for easy maintenance.
