[0002] With the continuous development of technology, there are more and more types of electrical appliances. The most indispensable thing for electrical appliances is power supply. Power supply requires the use of cables. Cables are often quite long and need to be supported by utility poles. Porcelain insulators are needed to fix them on the utility poles. Therefore, a special type of anti-pollution needle-type porcelain insulator for high-voltage lines is used.

[0022] This utility model provides, for example Figures 1-3 The illustrated lightning rod-type porcelain insulator with adhesive bonding includes a porcelain component 1. A steel cap 2 is adhesively bonded to the top of the porcelain component 1. A wire groove 12 is provided at the top of the steel cap 2 for connecting with cables. The cable can be fixed by binding, which is not limited here. Furthermore, the porcelain component 1 is coated with a silicone rubber coating, which provides excellent insulation and weather resistance, maintaining its performance even under harsh weather conditions. In addition, the silicone rubber coating has a certain degree of elasticity and self-healing ability, resisting mechanical stress caused by lightning strikes and preventing cracks and damage to the insulator surface.

[0023] The bottom of the ceramic component 1 is glued with a steel foot 3. The bottom of the steel foot 3 has a slot, and a rod is inserted into the slot. The bottom of the rod is fixedly connected to an adjusting rod 4. The rod slides inside the slot, so that the combined height of the steel foot 3 and the adjusting rod 4 is adjustable, thereby adjusting the installation height of the ceramic component 1. Furthermore, a sliding groove, slider, or other structure (not shown in the figure) can be provided between the slot and the rod, so that the steel foot 3 and the adjusting rod can only rotate synchronously. A threaded hole 13 is provided on the side wall of the steel foot 3. The threaded hole 13 corresponds to the position of the slot. The threaded hole 13 is threadedly connected to a screw 14 for fixing the rod. Multiple longitudinally distributed limiting holes can be provided on the rod. When the screw 14 is inserted into the corresponding limiting hole, the steel foot 3 and the adjusting rod 4 can be fixed and locked. This locking positioning is a common existing technology and will not be described in detail here.

[0024] The adjusting rod 4 is provided with a locking assembly for fixing it to the power equipment. The locking assembly includes a fixing block 5 and a nut 6. The fixing block 5 is fixedly connected to the adjusting rod 4, and the nut 6 is threadedly connected to the adjusting rod 4. The fixing block 5 is located above the nut 6. The outer circumference of the fixing block 5 is a regular hexagon, which is consistent with the shape of the nut 6, so that the operator can use a wrench or other means to limit the position.

[0025] In actual use, the bottom end of the adjusting rod 4 is inserted into the mounting hole on the power equipment (such as a crossarm) from top to bottom. Then, the nut 6 is aligned with the bottom end of the adjusting rod 4 and rotated. The nut 6 cooperates with the fixing block 5 to complete the fixed installation of the adjusting rod 4.

[0026] Considering that porcelain insulators are easily subjected to the force exerted by cable swing during use, in order to improve the strength of the connection between steel foot 3 and adjusting rod 4, a fixing cap 7 is fixedly connected to steel foot 3, and a support ring 10 is arranged around the outside of adjusting rod 4. A support component for support is provided between fixing cap 7 and support ring 10.

[0027] In specific configuration, the support assembly includes an annular groove 8, a rotating ring 9, and a connecting rod 11. The annular groove 8 is located at the bottom of the fixed cap 7. The rotating ring 9 is threaded into the interior of the annular groove 8. The inner wall of the annular groove 8 has an internal thread, and the outer wall of the rotating ring 9 has an external thread. The internal and external threads mate, and the friction coefficient between them is appropriate to prevent arbitrary rotation. The top end of the connecting rod 11 is fixedly connected to the rotating ring 9, and the bottom end is fixedly connected to the support ring 10. The connecting rod 11 is inclined, and its top end is inclined towards the axis of the adjusting rod 4. Multiple connecting rods 11 are provided, and they are evenly distributed around the adjusting rod 4. The gap between two adjacent connecting rods 11 is appropriate and does not affect the use of a wrench to pass through the gap between two connecting rods 11 and connect with the fixed block 5.

[0028] After adjusting the height of the porcelain insulator 1 and fixing the adjusting rod 4, rotate the rotating ring 9 so that the support ring 10 abuts against the power equipment, forming a support and reinforcement at the connection between the steel foot 3 and the adjusting rod 4. Simultaneously, the support ring 10 increases the contact area, ensuring the strength of the support. This utility model, through the setting of the adjusting rod 4, fixing cap 7, support ring 10, and support components, facilitates the adjustment of the installation height of the porcelain insulator 1, and forms a support and reinforcement at the connection between the steel foot 3 and the adjusting rod 4. At the same time, the support ring 10 increases the contact area, ensuring the stability of the electrical porcelain insulator in use.
