Description

Technical Field

[0001] The utility model relates to the field of electric porcelain insulators, in particular to an electric porcelain insulator which is convenient for connection and assembly. Background Art

[0002] Due to its inherent insulating properties, ceramics are widely used as insulators, also known as porcelain insulators. Insulators are devices installed between conductors at different potentials, or between a conductor and a grounded structure, capable of withstanding voltage and mechanical stress. Insulators come in a wide variety of types and shapes. While the structures and appearances of different types of insulators vary significantly, they all consist of two main components: the insulating element and the connecting hardware.

[0003] After searching, a utility model assembled electric porcelain insulator with publication number CN209312505U was found, comprising an assembly head, a pillar, a composite umbrella group, a copper foot and a copper foot bolt, the bottom of the assembly head being fixedly connected to a connecting head, the bottom of the connecting head being fixedly connected to one end of the pillar, and the middle part of the outer surface of the pillar being fixedly connected to a composite umbrella group. In the utility model, through the cooperative operation mode of being provided with a fixing hole and a positioning hole, and with the cooperation of a slide groove and a baffle, when the electric porcelain insulator needs to be assembled, first the bottom edge of the electric porcelain insulator is slid into the inside of the slide groove, and the electric porcelain insulator can be fixed through the obstruction of the baffle, and then the center position of the electric porcelain insulator is aligned with the positioning hole. At this time, the four corners of the electric porcelain insulator are aligned with the fixing hole, and then the electric porcelain insulator is pressed downward to position and fix the electric porcelain insulator, effectively improving the assembly convenience of the electric porcelain insulator. The utility model is practical and effective and suitable for wide promotion.

[0004] Most existing porcelain insulators are integrally formed when in use, and users cannot stack and combine the insulators according to actual needs, which limits the use of the insulators. In the above-mentioned comparative case, the assembled porcelain insulators can only be disassembled and assembled at the assembly head at the upper end, but the composite umbrella group cannot be disassembled and assembled, thereby preventing the umbrella groups from being stacked and combined according to the installation environment required by the user.

[0005] Therefore, it is necessary to invent a kind of electric porcelain insulator that is convenient to connect and combine to solve the above problems. Utility Model Content

The telescopic rods 801 are inserted into the holes 5 on both sides of the insulating rod 4 to limit and fix them. Then, the second insulating umbrella 9 is sleeved on the outside of the insulating rod 4, and the fixing sleeve 10 below the second insulating umbrella 9 is tightened on both sides. The limit blocks 11 are inserted into the limit grooves 702 on both sides of the connecting sleeve 701, and then the second insulating umbrella 9 is pressed to drive the limit blocks 11 to extend and retract in the limit grooves 702. When the limit blocks 11 are extended to the bottom, the second insulating umbrella 9 is rotated to move the limit blocks 11 in the limit grooves 702. When the limit blocks 11 move to the bottom again, the second insulating umbrella 9 is released, and the extrusion ring 705 and the fixing sleeve 10 are pushed back by the telescopic sleeve rod 703 and the first spring 704 inside the connecting sleeve 701 to clamp the limit blocks 11 in the limit grooves 702 for limiting.

The inside of the connecting sleeve 701 is provided with a telescopic sleeve rod 703, and the outside of the telescopic sleeve rod 703 is provided with a first spring 704. The upper end of the telescopic sleeve rod 703 is fixedly installed with an extrusion ring 705. The telescopic sleeve rod 703 inside the connecting sleeve 701 and the first spring 704 outside are arranged so that the extrusion ring 705 squeezes the second insulating umbrella 9 and the fixing sleeve 10 and the limiting block 11 below, and the limiting block 11 is limited and clamped in the limiting grooves 702 on both sides of the connecting sleeve 701, making the connection and combination more convenient and quick.

[0032] like Figure 3 and Figure 4 As shown, the limiting groove 702 is set to be U-shaped, the telescopic sleeve rod 703 is distributed in a ring array in the connecting component 7, the telescopic sleeve rod 703 is fixedly connected to the extrusion ring 705, and the limiting groove 702 is set to be U-shaped, so that the fixing sleeve 10 and the limiting block 11 below the second insulating umbrella 9 can be limited and fixed in the limiting groove 702.

[0033] like Figure 1 and Figure 4 As shown, the limiting assembly 8 includes a telescopic rod 801, a pull ring 802, a fixed block 803, and a second spring 804. The telescopic rod 801 is arranged on both sides of the limiting assembly 8, one end of the telescopic rod 801 is fixedly installed with a pull ring 802, the outside of the telescopic rod 801 is fixedly installed with a fixed block 803, and the outside of the telescopic rod 801 is provided with a second spring 804.

[0034] like Figure 1 、 Figure 2 and Figure 5As shown, the upper end of the insulating rod 4 is movably connected to a mounting sleeve 13, and fixing plates 14 are fixedly installed on both sides above the mounting sleeve 13. A screw 15 passes through one side of the fixing plate 14, and a nut 16 is movably connected to one end of the screw 15. The mounting sleeve 13 and the fixing plate 14 are threadedly connected at the upper end of the insulating rod 4, which makes it easy to clamp the cable in the fixing plate 14, and the screw 15 and the nut 16 are used to clamp the cable in the middle to maintain stability.

When the first insulating umbrella 6 is in place, the pull ring 802 is released so that the telescopic rod 801 and the second spring 804 on the outside rebound and retract, and the telescopic rod 801 is inserted into the hole grooves 5 on both sides of the insulating rod 4 to limit and fix the first insulating umbrella 6, and then the second insulating umbrella 9 is sleeved on the outside of the insulating rod 4, so that the limit blocks 11 on both sides of the fixing sleeve 10 below the second insulating umbrella 9 are aligned with the limit grooves 702 on both sides of the connecting sleeve 701, and then the second insulating umbrella 9 is pressed to drive the limit blocks 11 to retract and retract in the limit grooves 702. When it is retracted to the bottom, the second insulating umbrella 9 is rotated again to make the limit blocks 11 move in the limit grooves 702, and when it moves horizontally to the bottom, it is released. The second insulating umbrella 9 pushes the extrusion ring 705 and the fixing sleeve 10 and the second insulating umbrella 9 above through the telescopic sleeve rod 703 inside the connecting sleeve 701 and the rebound of the first spring 704, and the limit block 11 is clamped in the limit groove 702 for limit fixing. This clamping method is more convenient and quick to connect and combine. Then, according to the above steps, the next group of first insulating umbrellas 6 and second insulating umbrellas 9 are connected and combined. When the combination is completed, the mounting sleeve 13 is sleeved on the external thread 12 on the outer side of the upper end of the insulating rod 4 and tightened. When the assembly is completed, the entire porcelain insulator is installed in the air, the flange 2 below is threaded to the specified position, and the cable is placed between the fixing plates 14 above the mounting sleeve 13. Next, the screw 15 is passed through the fixing plate 14 to limit the cable inside. Finally, the nut 16 is sleeved on one end of the screw 15 and tightened. In this way, the use process of the porcelain insulator that is easy to connect and combine is completed.
