[0002] A high-voltage porcelain insulator is a rigid insulator composed of one or more insulating parts permanently cemented to a metal base and sometimes with a cap, and can be rigidly installed on a support structure by means of a stud bolt or one or more bolts mounted on the metal base. It is mainly used for insulation and supporting conductors in AC power lines with a nominal voltage higher than 1000V, a frequency not greater than 100Hz, an altitude not exceeding 1000m, and in ordinary areas and medium and heavy pollution areas.

[0003] At present, the existing high-voltage porcelain insulators are fixed by bolts during installation. This method will increase the labor intensity during the installation of high-voltage porcelain insulators and reduce the work efficiency during the installation process; moreover, the bolts are prone to back-off and loosening after long-term use, so the high-voltage porcelain insulators are not firmly installed after installation, which brings great troubles to people's use. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: a high-voltage porcelain insulator installation structure, including a left porcelain insulator and a right porcelain insulator located on one side of the left porcelain insulator. A female sleeve is sleeved at the end of the left porcelain insulator, and the female sleeve is connected and fastened to the left porcelain insulator through a clockwise fixing mechanism; a male sleeve base is sleeved at the end of the female sleeve, and the male sleeve base is sleeved and matched with the female sleeve, and the male sleeve base is connected and fastened to the right porcelain insulator through a counterclockwise fixing mechanism; three double-lock structures are arranged between the female sleeve and the male sleeve base, and the included angle between adjacent double-lock structures is 120 degrees. The double-lock structure is used to lock and fix the female sleeve and the male sleeve base.

[0006] Preferably, the double-lock structure is composed of an outer card slot, a pin, a hollow slot, an inner buckle slot, an outer pull spring and an elastic buckle. There are three groups of outer card slots, and the three groups of outer card slots are opened inside the male sleeve base.

[0007] Preferably, there are three groups of hollow slots, and the three groups of hollow slots are opened inside the female sleeve. A pin is movably arranged inside the hollow slot, and when the female sleeve and the male sleeve base are in a locked state, the top end of the pin penetrates through the hollow slot and extends into the outer card slot.

[0008] Preferably, three sets of internal snap grooves are provided, and the three sets of internal snap grooves are opened on the surface of the male socket. The bottom end of the external card slot penetrates through the hollow groove and is provided with an elastic buckle. When the female sleeve hoop and the male socket are in a locked state, the top end of the elastic buckle is engaged with the internal snap groove.

[0009] Preferably, an external pulling spring is sleeved on the surface of the external card slot, the top end of the external pulling spring is fixedly connected to the surface of the hollow groove, and the bottom end of the external pulling spring is fixedly connected to the surface of the pin.

[0010] Preferably, both the clockwise fixing mechanism and the counterclockwise fixing mechanism are composed of an arc-shaped sliding bar, an arc-shaped sliding frame and a blocking block. There are three sets of the arc-shaped sliding bar and the arc-shaped sliding frame. The three sets of arc-shaped sliding bars are integrally injection-molded on the surfaces of the left porcelain insulator and the right porcelain insulator, and the three sets of arc-shaped sliding frames are fixedly connected to the surfaces of the female sleeve hoop and the male socket, and the arc-shaped sliding bar and the arc-shaped sliding frame cooperate with each other.

[0021] The structure of an installation structure of a high-voltage electric porcelain insulator provided by the present utility model is as Figure 1 , Figure 2 and Figure 4As shown in the figure, it includes a left porcelain insulator 1 and a right porcelain insulator 11 located on one side of the left porcelain insulator 1. An end of the left porcelain insulator 1 is sleeved with a female ferrule 2, and the female ferrule 2 is connected and fastened to the left porcelain insulator 1 through a clockwise fixing mechanism 5; an end of the female ferrule 2 is sleeved with a male socket 3, and the male socket 3 is sleeved and matched with the female ferrule 2, and the male socket 3 is connected and fastened to the right porcelain insulator 11 through a counterclockwise fixing mechanism 6. Both the clockwise fixing mechanism 5 and the counterclockwise fixing mechanism 6 are composed of an arc-shaped slide bar 61, an arc-shaped slide frame 62 and a blocking block 63. There are three groups of arc-shaped slide bars 61 and arc-shaped slide frames 62. The three groups of arc-shaped slide bars 61 are integrally injection-molded on the surfaces of the left porcelain insulator 1 and the right porcelain insulator 11. The three groups of arc-shaped slide frames 62 are fixedly connected to the surfaces of the female ferrule 2 and the male socket 3, and the arc-shaped slide bar 61 and the arc-shaped slide frame 62 are matched with each other. A blocking block 63 is integrally injection-molded at the front end of the arc-shaped slide bar 61 on the surface of the left porcelain insulator 1 and the rear end of the arc-shaped slide bar 61 on the surface of the right porcelain insulator 11. When the left porcelain insulator 1 is installed with the female ferrule 2, after clockwise rotation and locking, it is blocked by the blocking block 63. When the right porcelain insulator 11 is installed with the male socket 3, after counterclockwise rotation and locking, it is blocked by the blocking block 63.

[0022] During implementation, the female ferrule 2 is installed on the surface of the left porcelain insulator 1 through the clockwise fixing mechanism 5. During installation, the arc-shaped slide frame 62 on the inner wall of the female ferrule 2 is aligned with the gap between the adjacent arc-shaped slide bar 61 and the blocking block 63 and sleeved on the end of the left porcelain insulator 1. After being sleeved, the female ferrule 2 is rotated clockwise, so that the arc-shaped slide frame 62 and the arc-shaped slide bar 61 are buckled with each other. After buckling, the blocking block 63 blocks the arc-shaped slide frame 62 in the clockwise direction; similarly, the male socket 3 is installed with the right porcelain insulator 11 through the counterclockwise fixing mechanism 6. During installation, the male socket 3 is rotated counterclockwise, so that the arc-shaped slide frame 62 and the arc-shaped slide bar 61 are buckled with each other. After buckling, the blocking block 63 blocks the arc-shaped slide frame 62 in the counterclockwise direction. Subsequently, the female ferrule 2 and the male socket 3 are installed and fixed through a double-lock structure 4. After fixing, since the female ferrule 2 and the left porcelain insulator 1 are blocked by the blocking block 63 in the clockwise direction, and the male socket 3 and the right porcelain insulator 11 are blocked by the blocking block 63 in the counterclockwise direction.

[0023] Further, as Figure 2 and Figure 3As shown in the figure, three sets of double-lock structures 4 are provided between the female sleeve hoop 2 and the male socket 3, and the included angle between adjacent double-lock structures 4 is 120 degrees. The double-lock structure 4 is used to lock and fix the female sleeve hoop 2 and the male socket 3. The double-lock structure 4 is composed of an outer card slot 41, a pin 42, a hollow slot 43, an inner snap groove 44, an outer tension spring 45, and an elastic buckle 46. There are three sets of outer card slots 41, and the three sets of outer card slots 41 are opened inside the male socket 3. There are three sets of hollow slots 43, and the three sets of hollow slots 43 are opened inside the female sleeve hoop 2. A pin 42 with a bottom-mounted limit piece is movably arranged inside the hollow slot 43. When the female sleeve hoop 2 and the male socket 3 are in the locked state, the top end of the pin 42 penetrates through the hollow slot 43 and extends into the inner part of the outer card slot 41. There are three sets of inner snap grooves 44, and the three sets of inner snap grooves 44 are opened on the surface of the male socket 3. The bottom end of the outer card slot 41 penetrates through the hollow slot 43 and is installed with an elastic buckle 46. When the female sleeve hoop 2 and the male socket 3 are in the locked state, the top end of the elastic buckle 46 is buckled with the inner snap groove 44. An outer tension spring 45 is sleeved on the surface of the outer card slot 41, and the top end of the outer tension spring 45 is fixedly connected to the surface of the hollow slot 43, and the bottom end of the outer tension spring 45 is fixedly connected to the surface of the pin 42.

[0024] During implementation, the male socket 3 is sleeved on the surface of the female sleeve hoop 2. When sleeved, the pins 42 and 56 are in a compressed state. After being sleeved in place, the elastic buckle 46 will reset and snap into the inner part of the inner snap groove 44 to achieve primary fixation. At the same time, the pin 42 will also snap into the inner part of the outer card slot 41 under the elastic force of the outer tension spring 45 and the limiting effect of the limit piece on its surface to achieve secondary fixation. Therefore, the problem of requiring bolt fixation in the prior art is solved, and the double fixation increases the firmness of the high-voltage porcelain insulator after installation.

[0025] Working principle: When in use, first, the female sleeve hoop 2 is installed on the surface of the left porcelain insulator 1 through the clockwise fixing mechanism 5. During installation, the arc-shaped sliding frame 62 on the inner wall of the female sleeve hoop 2 is aligned with the gap between the adjacent arc-shaped sliding strips 61 and the blocking block 63 and sleeved on the end of the left porcelain insulator 1. After being sleeved, the female sleeve hoop 2 is rotated clockwise, so that the arc-shaped sliding frame 62 and the arc-shaped sliding strip 61 are buckled with each other. After buckling, the blocking block 63 blocks the arc-shaped sliding frame 62 in the clockwise direction; similarly, the male socket 3 is installed with the right porcelain insulator 11 through the counterclockwise fixing mechanism 6. During installation, the male socket 3 is rotated counterclockwise, so that the arc-shaped sliding frame 62 and the arc-shaped sliding strip 61 are buckled with each other. After buckling, the blocking block 63 blocks the arc-shaped sliding frame 62 in the counterclockwise direction. Subsequently, the female sleeve hoop 2 and the male socket 3 are installed and fixed through the double-lock structure 4. After fixation, since the female sleeve hoop 2 and the left porcelain insulator 1 are blocked by the blocking block 63 in the clockwise direction, and the male socket 3 and the right porcelain insulator 11 are blocked by the blocking block 63 in the counterclockwise direction, they will be automatically locked and fixed after installation, which increases the convenience of installing the high-voltage porcelain insulator and reduces the labor intensity during the installation of the high-voltage porcelain insulator.

[0026] When the double-lock structure 4 of the present utility model is implemented, the male socket 3 is sleeved on the surface of the female ferrule 2. When sleeved, the latch pins 42 and 56 are in a compressed state. After being sleeved in place, the elastic buckle 46 will reset and snap into the inner buckle groove 44 to achieve primary fixation. At the same time, the latch pin 42 will also snap into the outer card slot 41 under the elastic force of the outer pull spring 45 and the limiting effect of the limiting piece on its surface to achieve secondary fixation. Therefore, the problem of bolt fixation required in the prior art is solved, and the double fixation increases the firmness of the high-voltage porcelain insulator after installation.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
