Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0022] A pluggable quick-installation high-voltage bushing, comprising a base 1, a docking groove 2 is provided on one side of the base 1, a plug-in block 3 is provided inside the docking groove 2, a bushing body 4 is fixedly provided on the end of the plug-in block 3 away from the base 1, a mounting block 5 is fixedly provided on the outside of the plug-in block 3, accommodating grooves 6 are provided on both upper and lower surfaces of one side of the base 1, splicing grooves 7 are provided inside the upper and lower ends of the side of the mounting block 5 close to the base 1, a through groove 8 is provided at the bottom end of the splicing groove 7 close to the base 1, an installation mechanism is provided between the inside of the accommodating groove 6 and the splicing groove 7, and a disassembly mechanism is provided on the side of the splicing groove 7 away from the through groove 8;

[0023] Through the above solution, the pluggable and quick installation and removal function of the high-voltage bushing can be realized;

[0024] In this embodiment, preferably, the mounting mechanism includes a guide column 9, a movable plate 10, a first spring 11 and a block 12, the guide column 9 is fixedly arranged inside the accommodating groove 6, the movable plate 10 is movably arranged on the outer side of the top of the guide column 9 through the mounting hole, the first spring 11 is installed on the outer side of the bottom end of the guide column 9, the top of the first spring 11 is connected to the movable plate 10, one end of the movable plate 10 passes through the through groove 8 and is located inside the splicing groove 7, and a block 12 is fixedly arranged at one end of the movable plate 10 inside the splicing groove 7;

[0025] Through the above scheme, by using the installation mechanism, when the operator installs the sleeve on the base 1, he only needs to align the through groove 8 with the block 12 on the movable plate 10, and then complete the work of inserting the plug-in block 3 into the docking groove 2 to complete the quick plug-in installation of the sleeve. The operation is simple and convenient, so that the sleeve has good convenience when installed and used;

[0026] In this embodiment, preferably, the disassembly mechanism includes a push rod 13, a pressure block 14 and a second spring 15. The push rod 13 is movably arranged on the side of the splicing groove 7 away from the through groove 8 through the mounting hole, and the pressure block 14 is fixedly arranged on the end of the push rod 13 close to the block 12. The second spring 15 is installed outside one end of the push rod 13 in the splicing groove 7, and one end of the second spring 15 is connected to the pressure block 14;

[0027] Through the above scheme, the use of the disassembly mechanism allows the sleeve to be removed by lifting and pressing the push rod 13 when disassembly is required, thereby achieving the effect of convenient disassembly of the sleeve, and the operation is also simple and convenient, so that it is convenient for operators to inspect and repair the sleeve. The use of the second spring 15 can ensure the position of the pressing block 14 when not in use, thereby avoiding erroneous operation caused by the contact between the pressing block 14 and the clamping block 12 when disassembly is not required, thereby ensuring the use effect of the disassembly mechanism;

[0028] In this embodiment, preferably, the end surface of the block 12 away from the movable plate 10 is inclined;

[0029] Through the above solution, the block 12 with an inclined surface at one end can be displaced when under pressure;

[0030] In this embodiment, preferably, the end surface of the pressing block 14 away from the push rod 13 is inclined;

[0031] Through the above solution, when the pressing block 14 with an inclined surface at one end contacts the card block 12, it can better contact the inclined surface of the card block 12 to provide pressure for the card block 12;

[0032] In this embodiment, preferably, a limit block 16 is fixedly provided at one end of the push rod 13 at both upper and lower ends of the side of the mounting block 5 away from the base 1;

[0033] Through the above solution, the limiting block 16 is used to provide a limiting effect on the push rod 13 to prevent the push rod 13 from being separated from the mounting hole connected to the mounting block 5 under the action of the second spring 15 when the disassembly mechanism is not used.

[0034] When a pluggable quick-install high-voltage bushing of this embodiment is used, it is necessary to ensure that the through groove 8 on the mounting block 5 on the bushing body 4 is aligned with the end of the movable plate 10 with the card block 12, and then the plug-in block 3 is inserted into the docking groove 2. In this process, the inclined surface of the card block 12 is resisted by the side wall of the through groove 8, which will drive the movable plate 10 to press down the first spring 11 so that the card block 12 passes through the through groove 8. When the card block 12 is located in the splicing groove 7, the first spring 11 will reset so that the side wall of the card block 12 is in contact with the inner wall of the splicing groove 7, thereby completing the connection and fixing between the base 1 and the mounting block 5. When it is necessary to remove the sleeve from the base 1, the operator needs to lift the installation block 5 and press one end of the two push rods 13 at the same time to make the inclined surface of the pressing block 14 contact with the inclined surface of the clamping block 12, and make the pressing block 14 stretch the second spring 15, so that the clamping block 12 is pressed and moved downward. After that, the operator can directly remove the sleeve from the base 1. After that, the pressing block 14 is reset under the action of the second spring 15, thereby avoiding erroneous operation caused by the contact between the pressing block 14 and the clamping block 12 when disassembly is not required, thereby realizing the pluggable and quick installation and disassembly function of the sleeve.
