Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a bowl-shaped disc insulator. Background Art

[0002] Insulators are insulating components used in electrical equipment to support conductors of transmission lines and power equipment.

[0003] In the prior art, insulators are a very important component in power transmission and distribution systems. They are used to isolate high-voltage power sources from brackets and prevent electrical leakage or insulation damage. Bowl-shaped disc insulators are a very common insulator. The connecting flange at the end of the insulator is connected to the line and fixed with bolts to achieve the function of supporting and insulating the cable.

[0004] However, traditional bowl-shaped disc insulators are fixed to the line by bolts, and most of the insulators are installed at high altitudes, which are easily affected by wind and shake. The bolts are easily loosened when shaken, and the loose bolts make the insulator unstable, which is not conducive to its operation. Utility Model Content

[0005] The purpose of the utility model is to provide a bowl-shaped disc insulator to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a bowl-shaped disc insulator, the bowl-shaped disc insulator comprising:

[0007] Bolt; a sliding groove is formed at the end of the bolt, a push block groove is formed on the surface of the sliding groove, a transmission block is formed on the surface of the push block groove, a limit rod is fixed on the surface of the transmission block, and a first spring is sleeved on the arc surface of the limit rod;

[0008] The nut has an annular groove on its surface, a rotating ring on its surface, a receiving block on its surface, a pull plate on its surface, and a push block on its lower surface.

[0009] Preferably, a through hole is provided on the inner wall of the push block groove, a limiting groove is provided on the end of the annular groove, a limiting hole is provided on the inner arc surface of the nut, a storage groove is provided inside the storage block, a notch is provided on the end of the storage groove, a guide rod is fixed on the lower surface of the pull plate, and a second spring is sleeved on the arc surface of the guide rod.

[0010] Preferably, there are multiple groups of through holes, which are symmetrically distributed on the arc surface of the bolt, and there are multiple groups of limit rods, which are symmetrically distributed on the surface of the transmission block. The limit rods correspond to the through holes, and the limit rods are clamped in the through holes, and the two are movably connected.

[0011] Preferably, the size of the annular groove is the same as that of the rotating ring, the size of the limiting groove is the same as that of the storage block, the size of the rotating ring is larger than that of the storage block, and the rotating ring corresponds to the annular groove, and the rotating ring is clamped in the annular groove.

[0012] Preferably, there are multiple groups of limiting holes, which are symmetrically distributed on the inner arc surface of the nut, and the limiting rods correspond to the limiting holes, the limiting rods are clamped in the limiting holes, and the two are movably connected.

[0013] Preferably, the storage grooves are provided in multiple groups, which are symmetrically distributed inside the storage block, and the guide rods are provided in multiple groups, which are symmetrically distributed on the lower surface of the pull plate, and the guide rods correspond to the storage grooves, and the guide rods are clamped in the storage grooves, and the two are movably connected.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The bolt is then pulled and the nut is tightened on the bolt surface. The pull plate is then stopped. Due to the elasticity of the second spring, the second spring pushes the guide rod to move and the push block to move at the same time. The movement of the push block will push the transmission block to move horizontally, so that the limit rod fixed on the surface of the transmission block is stuck in the limit hole. Under the restriction of the limit rod, the nut cannot rotate on the bolt surface, thereby preventing the bolt from loosening. When the pull plate is pulled, the first spring pushes the transmission block to move, and the limit rod will not disengage from the through hole. The end of the limit rod is located in the inner wall of the through hole. The structure is simple and easy to operate, thereby preventing the bolt from loosening when the insulator body is connected to the line, which is beneficial to improving its use effect.

[0033] On the basis of the first embodiment, in order to prevent the bolt 3 from loosening, a through hole 6 is provided on the inner wall of the push block groove 7, a limiting groove 10 is provided on the end of the annular groove 9, a limiting hole 11 is provided on the inner arc surface of the nut 4, a receiving groove 18 is provided inside the receiving block 13, and a notch 19 is provided on the end of the receiving groove 18. A guide rod 21 is fixed to the lower surface of the pull plate 5, and a second spring 20 is sleeved on the arc surface of the guide rod 21. Due to the elasticity of the second spring 20, the second spring 20 pushes the guide rod 21 to move, and at the same time moves the push block 14. The movement of the push block 14 will push the transmission block 17 to move horizontally;

[0034] There are multiple groups of through holes 6, which are symmetrically distributed on the arc surface of the bolt 3. There are multiple groups of limit rods 15, which are symmetrically distributed on the surface of the transmission block 17. The limit rods 15 correspond to the through holes 6. The limit rods 15 are clamped in the through holes 6, and the two are movably connected. When the pull plate 5 is pulled, the first spring 16 pushes the transmission block 17 to move, and the limit rod 15 will not be separated from the through hole 6. The end of the limit rod 15 is located in the inner wall of the through hole 6.

[0035] The size of the annular groove 9 is the same as that of the rotating ring 12, the size of the limiting groove 10 is the same as that of the receiving block 13, and the size of the rotating ring 12 is larger than that of the receiving block 13, and the rotating ring 12 corresponds to the annular groove 9, and the rotating ring 12 is clamped in the annular groove 9, so the rotating ring 12 will not fall out of the annular groove 9;

There are multiple groups of guide rods 21, which are symmetrically distributed on the lower surface of the pull plate 5.

Due to the elasticity of the second spring 20, the second spring 20 pushes the guide rod 21 to move, and at the same time moves the push block 14. The movement of the push block 14 will push the transmission block 17 to move horizontally, so that the limiting rod 15 fixed on the surface of the transmission block 17 is stuck in the limiting hole 11. Under the restriction of the limiting rod 15, the nut 4 cannot rotate on the surface of the bolt 3, thereby preventing the bolt 3 from loosening. When the pull plate 5 is pulled, the first spring 16 pushes the transmission block 17 to move, and the limiting rod 15 will not disengage from the through hole 6. The end of the limiting rod 15 is located in the inner wall of the through hole 6. This structure is simple and easy to operate, which prevents the bolt 3 from loosening when the insulator body 1 is connected to the line, and is beneficial to improving its use effect.
