Description

Technical Field

[0001] The utility model relates to the technical field of post composite insulators, and particularly relates to a post composite insulator. Background Technique

[0002] A post composite insulator refers to a special insulating control composed of a glass fiber epoxy resin pull rod, a silicone rubber umbrella skirt and a metal fitting. It is widely used in substations. Through the post composite insulator, it is possible to effectively use a narrow corridor to step up and transmit electricity, reduce the height of the tower pole, thereby saving a large amount of manpower, material resources and financial resources;

[0003] For example, publication number CN214012632U discloses a post composite insulator. A outer support rod is arranged below the first flange, a second flange is arranged below the outer support rod, and the first flange, the second flange and the outer support rod are fixedly connected through a fixing sleeve. The surface of the outer support rod is fixedly provided with first umbrella bodies at equal intervals. The structure of the utility model is simple and has good anti-pollution ability. When the dirt in the air falls on the insulator, due to the convex and concave surfaces provided on the lower surfaces of the first umbrella body and the second umbrella body, the dirt will not be evenly attached to the lower sides of the first umbrella body and the second umbrella body. Also, due to the difference in size between the first umbrella body and the second umbrella body and their staggered distribution, the anti-pollution ability of the insulator is improved to a certain extent. The insulating coating can further improve the insulation of the insulator, and the waterproof coating can improve the waterproof performance and prevent the water vapor in the external environment from invading the inner support rod;

[0004] However, in the prior art, most of the heights of post composite insulators are fixed, which is not convenient to adjust the height of the post composite insulator body according to the actual situation. Moreover, the installation operation of the post composite insulator body is relatively inconvenient, and most of them need to be fixed with bolts, and the disassembly is relatively inconvenient. For example, the above-listed comparative patent has this problem;

[0005] Therefore, we propose a post composite insulator to solve the above problems. Content of the Utility Model

The positioning mechanism is used for limiting between the installation column and the base, and the positioning mechanism drives a disassembly structure to be formed between the installation column and the base;

[0011] Meanwhile, the positioning mechanism is composed of a positioning spring arranged on the inner side of the lower end of the base and a positioning pin for limiting.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 7 , the present invention provides the following technical solutions.

[0033] Embodiment 1: To solve the problem that in the prior art, the height of the pillar composite insulator is mostly fixed, and it is inconvenient to adjust the height of the pillar composite insulator body 1 according to the actual situation. Therefore, in this embodiment, through the following technical solutions, a pillar composite insulator is provided with a pillar composite insulator body 1, a mounting pillar 2, and a mounting column 4. The lower end of the pillar composite insulator body 1 is welded with the mounting pillar 2. The outer surface of the pillar composite insulator body 1 is coated with insulating paint, which can achieve a good insulating effect. The mounting column 4 is penetrated through the middle by the mounting pillar 2, and the mounting pillar 2 is telescopically connected in the mounting column 4. As Figure 1 and Figure 2 shown, in the actual use process, according to the actual use requirements, by pulling the mounting pillar 2, the mounting pillar 2 slides telescopically in the mounting column 4, driving the pillar composite insulator body 1 to rise and fall, so as to facilitate the appropriate adjustment of the height of the pillar composite insulator body 1.

[0034] Embodiment 2: To solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a pillar composite insulator is provided with a connecting plate 10, a connecting block 11, a limiting rod 12, an auxiliary rod 13, and a fixing cap 14. Both the left and right ends of the connecting plate 10 form a front-back sliding structure with the connecting block 11, and the connecting blocks 11 are respectively fixedly connected to the left and right sides of the upper end of the mounting column 4. The middle of the connecting plate 10 is fixedly connected with the limiting rod 12, and the limiting rod 12 is slidably connected to the front side of the upper end of the mounting column 4. The connecting plate 10 is inserted into the mounting hole 3 at the corresponding position. Both the left and right sides of the front end of the connecting plate 10 are penetrated by the auxiliary rod 13, and the auxiliary rod 13 is fixedly connected to the front side of the upper end of the mounting column 4. The outer surface of the auxiliary rod 13 is threadedly connected with a fixing cap 14 for locking and limiting, and the fixing cap 14 is attached to the front side of the connecting plate 10. AsFigure 3 , Figure 6 and Figure 7 As shown in Figure 3 , Figure 6 and Figure 7 , after the height adjustment is completed, by moving the connecting plate 10, the connecting plate 10 slides between the connecting block 11, and at the same time, the connecting plate 10 slides between the auxiliary rod 13. The connecting plate 10 drives the limiting rod 12 to slide between the mounting column 4, so that the limiting rod 12 moves backward and is inserted into the mounting hole 3 at the corresponding position, thereby facilitating the limitation between the mounting support 2 and the mounting column 4. Then, rotate the fixing cap 14 screwed on the outer surface of the auxiliary rod 13, so that the fixing cap 14 is attached to the front side of the connecting plate 10 to limit between the connecting plate 10 and the auxiliary rod 13, and prevent the limiting rod 12 from moving out of the mounting hole 3.

[0035] Embodiment 3: In order to solve the problem that the installation operation of the pillar composite insulator body 1 in the prior art is relatively inconvenient, and most of them need to be fixed by bolts, and the disassembly is relatively inconvenient. Therefore, in this embodiment, through the following technical solutions, a pillar composite insulator is provided with a mounting column 4, a base 5, a positioning mechanism 6 and a fixing hole 9. The mounting column 4 is inserted and mounted in the base 5, and a positioning mechanism 6 is provided at the lower end of the mounting column 4. The positioning mechanism 6 is used to limit between the mounting column 4 and the base 5, and the positioning mechanism 6 drives a disassembly structure between the mounting column 4 and the base 5. The positioning mechanism 6 is composed of a positioning spring 7 provided inside the lower end of the base 5 and a positioning pin 8 for limiting. The positioning pins 8 are respectively telescopically connected to the left and right sides of the lower end of the mounting column 4, and the lower side surface of the positioning pin 8 fits with the inner side of the upper end of the base 5. The positioning pin 8 is snap-connected in the fixing hole 9 for positioning, and the fixing holes 9 are respectively opened at the left and right ends of the base 5, as Figure 4 and Figure 5 shown. During installation, directly insert the mounting column 4 into the base 5. The positioning pin 8 contacts the upper end of the base 5 and is squeezed, so that the positioning pin 8 expands and contracts at the lower end of the mounting column 4. The positioning pin 8 squeezes the positioning spring 7, causing the positioning spring 7 to undergo elastic deformation. When the mounting column 4 is completely inserted into the base 5, at this time, the positioning spring 7 recovers its elastic deformation and pushes the positioning pin 8 to slide outward. The positioning pin 8 is snap-connected in the fixing hole 9, and thus the mounting column 4 and the base 5 can be limited, and the pillar composite insulator body 1 can be installed very conveniently. When disassembly is required, directly insert an external rod-shaped object into the fixing hole 9 to squeeze the positioning pin 8, so that the positioning pin 8 moves out of the fixing hole 9, thereby releasing the limitation between the mounting column 4 and the base 5, and then directly move the mounting column 4 upward to remove it from the base 5, thereby facilitating the disassembly, assembly and maintenance of the pillar composite insulator body 1.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
