[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes. Although the structure and appearance of different types of insulators vary considerably, they all consist of two main parts: insulating components and connecting hardware.

[0003] A search revealed existing publication number CN211294756U, which discloses a modular porcelain insulator, belonging to the technical field of porcelain insulators.

Furthermore, the disassembly of the porcelain insulator facilitates packaging and transportation. During the development of this invention, the inventors discovered the following problems with the existing technology:

[0004] Most porcelain insulators have different creepage distance requirements. Existing porcelain insulators are molded in one piece, so when changing the creepage distance, it is necessary to re-manufacture the porcelain insulators, which greatly reduces the installation efficiency of porcelain insulators.

[0005] Therefore, a modular porcelain insulator is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] As attached Figures 1 to 5 The illustrated modular porcelain insulator includes a connecting rod 1. Its features include: a connecting rod 2 fixedly connected to the lower surface of the connecting rod 1; a skirt 3 fixedly connected to the connection between the connecting rod 1 and the connecting rod 2; a fixing mechanism 4 provided on the upper surface of the connecting rod 1; the fixing mechanism 4 includes a lead screw 41 fixedly connected to the upper surface of the connecting rod 1; and a threaded groove 42 formed on the lower surface of the connecting rod 2, with the lead screw 41 threadedly connected to the threaded groove 42. This threaded connection allows the connecting rod 1... 1 and connecting rod 2 can be detachably assembled, which is convenient for operation when maintenance or replacement of parts is required. The outer arc surface of connecting rod 2 is provided with an injection hole 43. Through the injection hole 43, insulating adhesive can be injected into the inside after multiple sets of porcelain insulators are connected to ensure the stability of the connection. At the same time, in conjunction with the umbrella skirt 3, it can effectively prevent rainwater from entering the interior. The injection hole 43 is connected to the threaded groove 42. The upper surface of the screw column 41 is fitted with a protective sleeve 44, and the lower surface of the threaded groove 42 is fitted with a protective sleeve 45.

[0026] Specifically: When multiple sets of porcelain insulators need to be spliced, the protective sleeve 1 44 and the protective sleeve 2 45 are removed from the screw rod 41 and the threaded groove 42. After aligning the threaded groove 42 of one set of porcelain insulators with the screw rod 41 of another set, one set of porcelain insulators is rotated so that the screw rod 41 is screwed into the threaded groove 42. The two sets of porcelain insulators are then spliced. After splicing, insulating adhesive is injected into the threaded groove 42 through the injection hole 43 to fix the two sets of porcelain insulators.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown in the following description: The upper surface of the connecting rod 1 is provided with a compensation mechanism 5, which includes a gasket 51. The lead screw 41 passes through the gasket 51 and is slidably connected to the gasket 51.

[0029] In a preferred embodiment, the outer arc surface of the connecting rod 1 has a movable rod 52 passing through it and is slidably connected to the movable rod 52. The movable rod 52 can slide smoothly on the outer arc surface of the connecting rod 1, which makes the movement of the entire compensation mechanism possible. The movable rod 52 is hinged to one end of the bracket 53, and the washer 51 is hinged to the other end of the bracket 53. This connection allows the movable rod 52 and the bracket 53 to rotate at a certain angle, increasing the flexibility of the mechanism.

[0030] In a preferred embodiment, the upper surface of the connecting rod 1 is provided with an annular groove 54, and the upper surface of the movable rod 52 is provided with slots 55 in a linear array. The slots 55 are configured as pins 56 to provide multiple selectable fixing positions to meet different compensation requirements. The annular groove 54 on the upper surface of the connecting rod 1 provides a certain guiding and limiting function for the sliding of the movable rod 52, ensuring that the movable rod 52 moves within a specified path.

[0031] In a preferred embodiment, the upper surface of the connecting rod 1 has a pin 56 through it and is slidably connected to the pin 56. The pin 56 is slidably connected to the slot 55. When it is necessary to fix the position of the movable rod 52, the pin 56 is inserted into the corresponding slot 55 to lock the position of the movable rod 52.

[0032] The working process of this utility model is as follows: First, when multiple sets of porcelain insulators need to be spliced, if it is not necessary to completely tighten and splice the two sets of porcelain insulators, the pin 56 can be pulled upwards so that the pin 56 moves out of the slot 55 opened in the movable rod 52 and pushes the movable rod 52 into the connecting rod 1. The bracket 53 drives the pad 51 to move upwards. After stopping at the required position, the two sets of porcelain insulators can be tightened. The above is the working principle of this type of combined splicing porcelain insulator.
