Technical Field

[0001] This utility model relates to the field of surge arrester technology, specifically to a surge arrester that is easy to install. Background Technology

[0002] A surge arrester is an electrical device used to protect power system equipment from damage caused by lightning overvoltage or switching overvoltage; it ensures that the equipment insulation is not damaged by limiting transient overvoltage and discharging impulse current.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Lightning Arrester Easy to Install," patent application number: 202320761583.4. It includes a slide rail base, a lightning arrester body, and a mounting mechanism. A slide rail is fixedly connected to the rear side of the upper end face of the slide rail base. A slider is slidably mounted on the upper end face of the slide rail. A hinge is fixedly mounted at the center of the front end of the slider. A positioning rod is hinged to the front end of the slider. A fixing block is fixedly connected to the upper part of the front end face of the positioning rod. Multiple positioning slots are formed on the front side of the upper end face of the slide rail base. In this utility model, through... The slider, slide rail base, and slide rail are designed to easily and efficiently transport the surge arrester body to the installation position. The hinge, positioning rod, fixing block, and multiple positioning slots are designed to fix the surge arrester body in place when it reaches the installation position, facilitating the installation of the surge arrester body. However, the surge arrester in the above-mentioned case is installed by using multiple positioning slots in conjunction with positioning rods. This not only limits the installation efficiency but also damages the quality of the surge arrester body after multiple slots are opened, resulting in a compromised service life of the surge arrester and making it inconvenient for construction personnel to install.

[0004] Therefore, it is necessary to design and modify surge arresters to effectively prevent the phenomenon of complicated installation. Utility Model Content

The inner side of the connecting plate 11 is fixedly connected to an insert plate 12. The inner side of the insert plate 12 extends into the interior of the insert post 3.

[0034] refer to Figure 1 , Figure 2 and Figure 3 The top of the limiting plate 5 is fixedly connected to the limiting mechanism 13, which includes a fixed plate 14. Slider 15 is slidably connected to both sides of the top of the fixed plate 14. A concave plate 16 is fixedly connected to the top of the slider 15. A wheel rod 17 is fixedly connected to the rear side of the inner side of the concave plate 16. A triangular block 18 is slidably connected to the inner side of the wheel rod 17. A horizontal plate 19 is fixedly connected to the inner side of the triangular block 18. The bottom of the horizontal plate 19 is slidably connected to the concave plate 16.

[0035] As a technical optimization of this utility model, the setting of the limiting mechanism 13 can make the rubbing wheel 9 more stable when it stops rotating, and avoid the phenomenon of shaking.

[0036] refer to Figure 3 The top of the fixed plate 14 has grooves 21 on both sides, and the bottom of the slider 15 is slidably connected to the inside of the grooves 21.

[0037] As a technical optimization of this utility model, the sliding groove 21 enables the slider 15 to slide more smoothly inside the fixed plate 14, reducing the friction between the slider 15 and the fixed plate 14 and extending the service life of the slider 15.

[0038] refer to Figure 3 The outer side of the rolling wheel 9 is provided with a positioning groove 22, and the inner side of the positioning rod 20 is engaged inside the positioning groove 22.

[0039] As a technical optimization of this utility model, the positioning groove 22 enables the positioning rod 20 to be more securely engaged inside the rubbing wheel 9, preventing it from falling off.

[0040] refer to Figure 3 The top of the fixed plate 14 has movable grooves 23 on both sides, and the bottom of the horizontal plate 19 is slidably connected to the inside of the movable grooves 23.

[0041] As a technical optimization of this utility model, the setting of the moving groove 23 enables the horizontal plate 19 to move more stably and prevents tilting.

[0044] The working principle and usage process of this utility model are as follows: First, the user places the surge arrester assembly 2 on the top of the base plate 1, so that the plug 3 is inserted into the inside of the surge arrester assembly 2. Then, the user rubs the rubbing wheel 9, which drives the positive and negative threaded rod 6 to rotate. The positive and negative threaded rod 6 drives the threaded sleeve 7 to move inward. The threaded sleeve 7 drives the bent rod 10 and the connecting plate 11 to move inward. The connecting plate 11 drives the plug plate 12 to move inward, so that the plug plate 12 passes through the inside of the plug 3, achieving the effect of convenient and quick installation. Then, the rubbing wheel 9 pulls the concave plate 16 without rotating. The concave plate 16 drives the wheel rod 17 to move inward. The wheel rod 17 drives the triangular block 18 and the horizontal plate 19 to move inward. The horizontal plate 19 drives the positioning rod 20 to move inward, so that the positioning rod 20 passes through the inside of the rubbing wheel 9, thus avoiding the phenomenon of the rubbing wheel 9 rotating back.

[0045] In summary, this easy-to-install surge arrester changes the traditional method of installing it by opening multiple slots. Instead, it uses a bent rod 10 to move the connecting plate 11 inward, which in turn moves the insert plate 12 inward, allowing the insert plate 12 to penetrate into the interior of the insert post 3. This prevents damage to the surge arrester body, ensures its service life, and makes installation easier for construction personnel.
