Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to an insulator which is easy to install. Background Art

[0002] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. They can increase creepage distance, achieve electrical insulation and mechanical fixation. They are usually made of glass or ceramic. When installing insulators, in order to avoid the inconvenience of using tools such as wrenches during installation, bolts will be set at the bottom of the insulator to directly thread and fix them with the threaded sleeve installed on the support column to complete the installation of the insulator.

[0003] According to the disclosed power insulator that is easy to install (publication number: CN217113993U), the installation column, threaded column, positioning sleeve, spring, abutment ring, limit ring and opening are used together in the above application, and the power insulator body can be directly installed without the aid of tools such as wrenches, thereby effectively avoiding the problem that the existing power insulators are inconvenient to install due to the need for tools such as wrenches.

[0004] However, in actual use of the above-mentioned equipment, during installation, the workers are required to rotate the power insulator body in order to fix the insulator body in the positioning sleeve. The body of some insulators is heavy, which results in a large amount of physical strength being wasted by the workers during the installation process, affecting the safety of the workers when they are supporting the columns up and down. At the same time, the surface of the insulator is relatively smooth, and it is inconvenient for the workers to rotate it forcefully, which in turn affects the installation efficiency. In view of this, we propose an insulator that is easy to install. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an insulator that is easy to install, comprising an insulator body, a screw is fixedly installed at the bottom end of the insulator body, a fixing cylinder is arranged below the insulator body, a positioning hole is opened on the upper surface of the fixing cylinder, a positioning rod is arranged on the bottom surface of the insulator body, the size of the positioning rod and the size of the positioning hole are mutually adapted, the positioning rod can be inserted into the positioning hole, the movement of the screw in the fixing cylinder can be guided and limited by the cooperation of the positioning rod and the positioning hole, so that the screw can only perform linear movement in the up and down directions inside the fixing cylinder, and an installation component is arranged inside the fixing cylinder, and the installation component includes:

[0007] An annular groove, the annular groove is formed on the inner wall surface of the fixed cylinder, a threaded sleeve is sleeved inside the annular groove, the threaded sleeve can rotate inside the annular groove, and a spherical groove is formed on the outer surface of the threaded sleeve;

[0008] An annular through groove, the annular through groove is provided on the outer surface of the fixing cylinder, an annular limiting groove is provided inside the annular through groove, and the upper and lower ends of the annular limiting groove respectively penetrate the upper and lower inner walls of the annular through groove;

[0009] A round rod is slidably installed inside the annular groove, the outer side of the round rod is fixedly connected to a limit block, and one end of the round rod close to the center of the fixed cylinder is fixedly installed with a hemisphere. When the round rod moves, it can drive the limit block and the hemisphere to move synchronously.

[0010] Preferably, the size of the threaded sleeve matches that of the screw rod, and the threaded sleeve and the screw rod can be threadedly connected to fix the insulator body, and the size of the spherical groove matches that of the hemisphere, and the hemisphere can enter the interior of the spherical groove.

[0011] Preferably, the limit block is located inside the annular limit groove, and the upper and lower side surfaces of the limit block are in contact with the upper and lower side inner wall surfaces of the annular limit groove. The annular limit groove can guide and limit the movement of the limit block, so that the limit block cannot move in the up and down directions inside the annular limit groove.

[0015] Compared with the prior art, the utility model provides an insulator that is easy to install and has the following features:

[0016] Beneficial effects:

[0017] 1. The insulator which is easy to install guides and limits the movement of the screw in the threaded sleeve through the cooperation of the provided positioning hole and the positioning rod so that the screw can only perform linear movement in the up and down directions in the threaded sleeve, and through the cooperation of the provided annular groove, threaded sleeve, spherical groove, annular through groove, annular limiting groove, limiting block and hemisphere, the staff only needs to slightly press down the insulator body at the beginning and continuously rotate the moving round rod to complete the thread fixation between the threaded sleeve and the screw. The operation is simple and convenient, and the staff does not need to select a heavier insulator body to complete the fixation, which results in the staff needing to waste a lot of physical strength during the installation process and the smooth surface of the insulator body is also easy to slip out of the hand.

[0018] 2. The insulator which is easy to install can avoid the formation of negative pressure inside the fixing tube during the installation process and hinder the installation by means of the air holes and the water-absorbing sponge. At the same time, the cooperation of the spring and the fixing plate can make the thread fixation between the screw and the threaded sleeve tighter, thereby enhancing the stability of the fixation of the insulator body.

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 6As shown, the utility model provides a technical solution: an insulator that is easy to install, including an insulator body 1, a screw rod 2 is fixedly installed at the bottom end of the insulator body 1, the outer side of the screw rod 2 is provided with an internal thread, a fixing cylinder 3 is arranged below the insulator body 1, an installation component is arranged inside the fixing cylinder 3, a positioning hole 6 is arranged on the upper surface of the fixing cylinder 3, and a positioning rod 7 is arranged on the bottom surface of the insulator body 1. When the insulator body 1 needs to be fixed by the fixing cylinder 3, the positioning rod 7 can be aligned with the positioning hole 6 and inserted, thereby limiting the movement of the screw rod 2 inside the fixing cylinder 3, so that the screw rod 2 can only perform linear motion in the up and down directions inside the fixing cylinder 3.

[0027] The installation assembly includes: an annular groove 401, an annular through groove 404 and a round rod 406. The annular groove 401 is opened on the inner wall surface of the fixed cylinder 3. The inner part of the annular groove 401 is sleeved with a threaded sleeve 402. The inner part of the threaded sleeve 402 is provided with an external thread. The size of the threaded sleeve 402 is adapted to the size of the screw 2. When the screw 2 reaches the top of the threaded sleeve 402, the staff squeezes the screw 2 downward. At this time, the threaded sleeve 402 is rotated to allow the screw 2 to move downward under the limitation of the positioning hole 6 and the positioning rod 7, enter the inner part of the threaded sleeve 402, and be threadedly connected with the threaded sleeve 402, thereby fixing the insulator body 1 to the upper end of the fixed cylinder 3. The outer surface of the threaded sleeve 402 is provided with a spherical groove 403. The number of the spherical grooves 403 is three, and the three spherical grooves 403 are opened on the outer side of the threaded sleeve 402 in an annular array.

[0028] An annular through groove 404 is provided on the outer surface of the fixed cylinder 3, and the interior of the annular through groove 404 is communicated with the interior of the annular groove 401, and an annular limiting groove 405 is provided inside the annular through groove 404, and a round rod 406 is slidably installed inside the annular through groove 404, and the round rod 406 can revolve around the threaded sleeve 402 inside the annular through groove 404, and a limiting block 407 is fixedly connected to the outer side of the round rod 406, and the limiting block 407 is located inside the annular limiting groove 405, and the upper and lower side surfaces of the limiting block 407 are in contact with the upper and lower side inner wall surfaces of the annular limiting groove 405, and the limiting block 407 cannot be separated from the inside of the annular limiting groove 405, but can revolve around the path of the annular limiting groove 405 or move close to and away from the threaded sleeve 402.

[0029] A hemispherical body 408 is fixedly installed at one end of the round rod 406 close to the center of the fixed cylinder 3. The size of the spherical groove 403 is adapted to the size of the hemispherical body 408. The staff can align the hemispherical body 408 with the spherical groove 403 and push the round rod 406 inward so that the hemispherical body 408 enters the spherical groove 403. At this time, the outer wall of the limit block 407 and the inner ring surface of the annular limit groove 405 fit each other, and push the round rod 406 to revolve around the threaded sleeve 402 within the limit of the limit block 407. The threaded sleeve 402 is driven to rotate through the cooperation of the hemispherical body 408 and the spherical groove 403. When the round rod 406 rotates to the front end of the annular groove 404, the spherical groove 403 located in the clockwise direction of the spherical groove 403 that is adapted to the hemispherical body 408 will reach the annular groove. At the rear end of 404, the staff can pull out the round rod 406 outward so that the hemispherical body 408 is separated from the spherical groove 403 being adapted. At this time, the outer wall of the limit block 407 will fit with the outer wall of the annular limit groove 405. The limit block 407 can limit the round rod 406 to prevent the round rod 406 from being separated from the fixing tube 3 and falling and becoming unable to be used. Then the staff adjusts the position of the round rod 406 so that the hemispherical body 408 is aligned with the spherical groove 403 reaching the rear end of the annular through groove 404, and repeats the above steps to drive the screw 2 to rotate continuously, so that the screw 2 enters the internal thread connection of the threaded sleeve 402 to complete the fixation of the insulator body 1. There is no need for the staff to rotate the heavier insulator body 1 to complete the fixation, thereby avoiding operating difficulties or the insulator body 1 falling out of the hand.

[0030] The bottom end of the left inner wall of the fixed cylinder 3 is provided with an air hole 501, and the interior of the fixed cylinder 3 is connected with the external space through the air hole 501. The interior of the air hole 501 is fixedly connected with a water-absorbing sponge 502. The air hole 501 can prevent the fixed cylinder 3 from forming a negative pressure when the screw 2 enters, resulting in an obstacle to the entry of the screw 2 and affecting the difficulty of fixing. The provided water-absorbing sponge 502 can isolate dust or water vapor in the outside air to prevent dust or water vapor from entering and affecting the service life of the spring 503. A spring 503 is fixedly installed on the inner bottom surface of the fixed cylinder 3, and a fixing plate 504 is fixedly installed on the top of the spring 503. When the screw 2 completely enters the threaded sleeve 402, the spring 503 will be squeezed by the fixing plate 504. At this time, the spring 503 is compressed to generate elastic potential energy, and a force is applied to the screw 2 to slightly lift the screw 2 upward, so that the threaded connection between the screw 2 and the threaded sleeve 402 is tighter, thereby increasing the stability of the fixation.

[0031] In the present invention, when in use, the staff aligns the positioning rod 7 with the positioning hole 6 and inserts the screw 2 into the interior of the fixing tube 3 so that the screw 2 reaches the upper end of the threaded sleeve 402. At this time, the staff aligns the hemispherical body 408 with the spherical groove 403 at the rear end of the annular groove 404 and pushes the hemispherical body 408 into the spherical groove 403. Then, under the limitation of the annular limiting groove 405 and the limiting block 407, the rotating round rod 406 revolves around the threaded sleeve 402. When the round rod 406 reaches the front end of the annular groove 404, the next ball The shaped groove 403 will reach the rear end of the annular through groove 404, and then the staff will pull out the round rod 406, insert the hemispherical body 408 into the spherical groove 403 at the rear, and continue to rotate the round rod 406 to drive the threaded sleeve 402 to rotate. The staff will initially press the insulator body 1 lightly with the other hand, so that the screw 2 can enter the threaded sleeve 402 for threaded fixation under the limitation of the positioning rod 7 and the positioning hole 6. At the same time, the round rod 406 will not be separated from the fixing tube 3 under the limitation of the annular limiting groove 405 and the limiting block 407, and the operation is simple.

[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
