Description

Technical Field

[0001] This utility model belongs to the field of insulating accessories technology, and in particular relates to an insulating accessory for a straight crossarm. Background Technology

[0002] The crossarm combines crossarm support and insulation functions. It is made of high-strength composite material vulcanized at high temperature, using high-molecular blended polymer raw materials and pre-formed by mold processing. It has excellent hydrophobic migration properties. The formula contains UV-resistant materials, which have excellent anti-aging properties. Therefore, the product can operate reliably in heavily polluted and harsh atmospheric environments. The shape adopts an arched design with a smooth surface to prevent birds from nesting and thus avoid bird damage accidents.

[0003] The insulating accessories currently available on the market for straight crossarms have the following problems when used:

[0004] 1. Traditional insulation accessories for straight crossarms are usually fixed in size and cannot be adjusted according to the length of the iron crossarm of the actual line. Therefore, they do not have the structure for splicing.

[0005] 2. When using most insulated accessories for straight crossarms, the crossarm body is often supported by metal. When the workers install the insulated accessories on the outside of the metal crossarm, they need to manually support it and use fasteners to install it. The position needs to be manually adjusted during installation and fixing. Therefore, the initial placement is not stable enough when using it. Utility Model Content

[0030] like Figure 1-6 As shown, this utility model discloses an insulating accessory for a straight crossarm, comprising a first insulator 1 and a second insulator 2. The second insulator 2 is located at the bottom of the first insulator 1, and a circular post 5 is located at the top of the second insulator 2. A sleeve 4 is located at the bottom of the first insulator 1, and a fixing seat 3 is located on the outside of the sleeve 4. Through holes 6 are opened inside the fixing seat 3 and the circular post 5, and fastening screws 7 pass through the through holes 6. By opening through holes 6, it is easy for fasteners to pass through the sleeve 4 and the circular post 5. A fastening nut 8 is threadedly connected to the outside of the fastening screw 7. A threaded seat 13 is installed on the top of the first insulator 1. By installing the sleeve 4 and the fixing seat 3 at the bottom of the first insulator 1, and the circular post 5 at the top of the second insulator 2, and the fastening nut 8 on the outside of the fastening screw 7, the first insulator 1 and the second insulator 2 are initially spliced ​​together. The fasteners are then removed, passing through the circular post 5 and the sleeve 4, and the external fasteners are tightened to fix the position. In this way, the length can be adjusted according to the actual length of the iron crossarm of the line, and it is suitable for metal crossarms of different lengths on site.

[0031] The bottom of the second insulator 2 is provided with a plate 17, and a magnetic block 16 is connected to the bottom of the plate 17. A metal frame 18 is provided at the bottom of the plate 17, and a threaded post 19 is provided at the top of the metal frame 18. A square hole 22 is opened at the top of the metal frame 18, through which the magnetic block 16 passes. The threaded post 19 passes through the plate 17, and a wing nut 20 is connected to the external thread of the threaded post 19. By installing the plate 17 and the magnetic block 16 at the bottom of the second insulator 2, and installing the metal frame 18 at the bottom of the plate 17, and opening a square hole 22 at the top of the metal frame 18, the metal frame 18 is fitted onto the outside of the metal crossarm. The plate 17 is installed in the metal frame 18 using fasteners. During subsequent installation, the magnetic block 16 is first embedded in the crossarm so that it can be directly attracted to the surface of the metal crossarm.

[0032] The top of the first insulator 1 has a slot 10, and the slot 10 is inlaid with a block 9. Because the slot 10 is provided, it is convenient to inlay the block 9 at the bottom of the top plate 11 into the slot 10.

[0033] The top of the card block 9 is connected to the top plate 11, and the bottom of the top plate 11 is connected to the protective cover 12. The installation of the protective cover 12 can protect the fasteners at the splicing point.

[0034] The external thread of the circular column 5 is connected to the threaded seat 13, and the top of the threaded seat 13 is connected to the mounting seat 14. The top of the mounting seat 14 has a mounting hole 15. Because of the threaded seat 13, it is convenient to install the mounting seat 14 on the first insulator 1 for connection.

[0035] A circular hole 21 is provided at the top of the plate 17, and a threaded post 19 passes through the inside of the circular hole 21. A mounting groove 23 is provided on the inner side of the metal frame 18. Because of the mounting groove 23, it is convenient to use fasteners to fix the metal frame 18 to the metal crossbeam.

[0036] The working principle of this insulating accessory for a straight crossarm is as follows: When using this device, the device body first needs to be moved to a suitable position. Once in the correct position, it can be placed on a flat surface. To facilitate the use of metal crossarms of any length, a splicing structure is installed. A sleeve 4 is installed at the bottom of the first insulator 1, with a fixing seat 3 fixedly connected to the outside of the sleeve 4. A circular column 5 is installed at the top of the second insulator 2. Both the circular column 5 and the fixing seat 3 have through holes 6 inside. A fastening nut 8 is installed on the outside of the fastening screw 7. First, the first insulator 1 and the second insulator 2 are initially spliced ​​together. The sleeve 4 is then fitted onto the outside of the circular column 5. The fastening screw 7 is then removed, passed through the through hole 6, and the fastening nut 8 on the outside of the fastening screw 7 is tightened to fix the position. This allows for length adjustment according to the actual length of the iron crossarm on the line, making it suitable for metal crossarms of different lengths on site. It features a splicing structure. To protect the fasteners from rain, snow, and rust, the top plate is removed. 11. A locking block 9 is provided on the inner side of the top plate 11. The locking block 9 is embedded in the locking groove 10, so that the protective cover 12 at the bottom of the top plate 11 can be sleeved on the outside of the fastener. In order to facilitate the initial stable placement of the insulating accessories on the outside of the metal cross plate, a plate body 17 and a magnetic block 16 are installed at the bottom of the second insulator 2, and a metal frame 18 is installed at the bottom of the plate body 17. A square hole 22 is opened at the top of the metal frame 18, and a threaded post 19 and a wing nut 20 are installed at the top of the metal frame 18. First, attach the metal frame 18 to the outside of the metal crossarm. Then, take out the insulating accessory and insert the magnetic block 16 at the bottom of the insulating accessory into the square hole 22. At the same time, insert the threaded post 19 through the round hole 21 and tighten the wing nut 20 to fix the metal frame 18 to the plate 17. The magnetic block 16 can then be embedded in the crossarm and can be directly adsorbed onto the surface of the metal crossarm. It is relatively stable when initially placed during application. Finally, take out the fastener and insert it into the mounting groove 23 to fix it to the metal crossarm.
