The large-scale use of GIS equipment has increased the market demand for its supporting products, especially the demand for GIS outlet bushings is increasing.

[0003] When the existing GIS casing is in use, it is necessary to install a sealing end cover on the outside of the GIS casing. The sealing end cover makes the GIS casing have a sealing effect to prevent liquid penetration, which affects the use of the GIS casing. When the GIS casing is installed, the outer flange of the sealing end cover is connected to the flange of the GIS casing. The two sets of flanges are limitedly connected by multiple sets of fixing bolts, so that the sealing end cover can be installed with the GIS casing. When the GIS casing is in use, the sealing end cover will age and needs to be replaced. The installation of the fixing bolts is troublesome when replacing the sealing end cover. Therefore, it is particularly important to improve the existing sealing end cover and design a new sealing end cover for GIS casing to solve the above technical defects and improve the practicality of the overall sealing end cover.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A sealing end cap for a GIS casing comprises a sleeve body 1, a connecting block 2 is arranged on the outer side of the sleeve body 1, a connecting ring 3 is arranged at one end of the connecting block 2 away from the sleeve body 1, a sealing cover 4 is arranged inside the connecting ring 3, and the connecting ring 3 is connected to the connecting block 2 through a connecting assembly 5, a sealing groove 6 is opened inside the connecting block 2, and sealing rings 7 are arranged at both ends of the sealing groove 6;

[0025] The connecting assembly 5 is used for the quick connection between the connecting ring 3 and the connecting block 2 .

[0026] Furthermore, the connecting assembly 5 is composed of a fixed block 8, a receiving groove 9, a limit block 10, a first compression spring 11 and a clamping block 12. The multiple groups of fixed blocks 8 are all located on the outside of the connecting block 2, the receiving groove 9 is opened inside the fixed block 8, the two groups of limit blocks 10 are respectively slidably connected to the two ends inside the receiving groove 9, the first compression spring 11 is located on the outside of the limit block 10, and the clamping block 12 is rotatably connected to the inside of the receiving groove 9 and is located between the two groups of limit blocks 10. When the connecting ring 3 needs to be connected to the connecting block 2, the connecting ring 3 can be quickly connected to the connecting block 2 through the connecting assembly 5, so that when the sealing cover 4 needs to be disassembled and replaced, it can be conveniently disassembled and replaced.

[0027] Among them, a connecting groove 13 is opened inside the accommodating groove 9 and on the outside of the limit block 10. The internal structure size of the connecting groove 13 is designed to correspond to the external structure size of the limit block 10. The limit block 10 is connected to the first compression spring 11 through the connecting groove 13, and the limit block 10 and the connecting groove 13 are slidingly connected. When the limit block 10 is displaced, the limit block 10 can be guided by the connecting groove 13 to prevent the limit block 10 from being offset. At the same time, the limit block 10 can be connected to the first compression spring 11, and the limit block 10 can be driven to displace through the first compression spring 11.

[0028] Secondly, the clamping block 12 extends to the outside of the fixed block 8 and is fixedly connected with a rotating rod 14. The rotating rod 14 and the fixed block 8 are rotatably connected. The rotating rod 14 is fixedly connected to the clamping block 12. Rotating the rotating rod 14 drives the clamping block 12 to rotate, so that the clamping block 12 can contact with the limit block 10, squeeze the limit block 10, and enable the limit block 10 to move.

[0029] Furthermore, multiple groups of fixing grooves 15 are opened inside the connecting ring 3, and the internal structure size of the fixing grooves 15 is designed to correspond to the external structure size of the fixing block 8. The connecting ring 3 is connected to the fixing block 8 through the fixing grooves 15. The fixing grooves 15 are connected to the fixing block 8 so that the connecting ring 3 can be connected to the fixing block 8.

[0030] Furthermore, limiting grooves 16 are provided at both ends of the fixing groove 15. The internal structure size of the limiting groove 16 is designed to correspond to the external structure size of the limiting block 10. The fixing groove 15 is connected to the limiting block 10 through the limiting groove 16. When the fixing groove 15 is connected to the fixing block 8, the limiting block 10 is moved to the inside of the limiting groove 16, so that the limiting block 10 can be connected to the fixing block 8 in a limiting manner, thereby enabling the connecting ring 3 to be connected to the connecting block 2, and thus enabling the sealing cover 4 to be connected to the sleeve body 1.

[0031] Furthermore, two groups of guide blocks 17 are slidably connected inside the accommodating groove 9 and above the clamping block 12. A second compression spring 18 is provided on the outer side of the guide block 17, and the guide block 17 is connected to the clamping block 12 through the second compression spring 18. When the guide block 17 is slidably connected to the accommodating groove 9 and the guide block 17 is displaced by the second compression spring 18, the guide block 17 can contact with the clamping block 12 to limit the clamping block 12, thereby increasing the limiting position of the clamping block 12 on the limit block 10, thereby increasing the stability of the connection between the limit block 10 and the limit groove 16 to prevent loosening.

[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, the sleeve body 1 is connected to the GIS sleeve, and the sleeve body 1 is fixed to the inner side of the GIS sleeve by fixing bolts. When the sealing cover 4 needs to be connected to the sleeve body 1, the connecting ring 3 is connected to the connecting block 2, so that the fixing groove 15 can be connected to the fixing block 8, and the rotating rod 14 is rotated to drive the clamping block 12 to rotate, so that the clamping block 12 can contact with the limit block 10, squeeze the limit block 10, so that the limit block 10 can be displaced, and the limit block 10 is displaced to the inside of the limit groove 16, so that the limit block 10 can be connected to the fixing block 8 in a limiting manner, so that the connecting ring 3 can be connected to the connecting block 2, so that the sealing cover 4 can be connected to the sleeve body 1, and the clamping When the block 12 contacts with the limit block 10, the second compression spring 18 drives the guide block 17 to move, so that the guide block 17 can contact with the clamping block 12, and limit the clamping block 12, thereby increasing the limit of the clamping block 12 on the limit block 10, so as to increase the stability of the connection between the limit block 10 and the limit groove 16 to prevent loosening. When the sealing cover 4 needs to be disassembled and replaced, the above operation is repeated in reverse to disconnect the connection between the clamping block 12 and the limit block 10, and the first compression spring 11 can drive the limit block 10 to move, so that the limit block 10 can be reset from the inside of the limit groove 16 to the inside of the accommodating groove 9, and the sealing cover 4 is disassembled. Compared with the existing sealing end cover, the utility model can improve the overall practicality of the sealing end cover through design.
