Description

Technical Field

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

[0002] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-voltage power lines. Many disc-shaped insulators are hung on one end of the tower to increase the creepage distance. They are usually made of glass or ceramics and are called insulators.

[0003] At present, most of the tension insulators on the market will be affected by airflow or other external forces at high altitudes, so that both ends are pulled by external forces. If there are no devices at both ends of the insulator that can weaken or reduce the direct force, structural deformation will easily occur, causing structural damage and reducing service life. Utility Model Content

[0004] The purpose of the utility model is to provide a tension insulator to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a tension insulator, comprising a main body shell, the main body shell is provided with a locking mechanism for tightening the main body shell, the main body shell is provided with an adjustment mechanism, and the locking mechanism comprises:

[0006] An internal fixing seat, wherein the side wall of the internal fixing seat is threadedly connected to the inner wall of the main body shell, the top of the internal fixing seat is fixedly connected to the bottom of the buffer tension spring, the top of the buffer tension spring is fixedly connected to the bottom of the connecting column, the side wall of the connecting column is slidably connected to the inner wall of the main body shell, the outer wall of the main body shell is fixedly connected to the bottom of the water-isolating ring, the inner wall of the water-isolating ring is fitted with the inner wall of the connecting column, the top of the connecting column is fixedly connected to the bottom of the connecting buckle, and the bottom sides of the connecting column are hinged to the bottom of the telescopic shaft;

[0007] A telescopic shaft, the top of the telescopic shaft is hinged to the top of the sliding seat, the bottom of the sliding seat is slidably connected to the side wall of the sliding groove, the top of the sliding seat is fixedly connected to one end of a pressure spring, the end of the pressure spring away from the sliding seat is fixedly connected to the side wall of the telescopic shaft, and a torsion spring is provided at the junction of the telescopic shaft and the connecting column.

[0008] Preferably, the inner wall of the main shell is fitted with the outer wall of the elastic soft board, the bottom of the elastic soft board is fixedly connected to the top of the support plate, the upper and lower ends of the support plate are fixed with elastic soft boards, the side wall of the support plate is fixedly connected to the side wall of the filling material, and the outer wall of the filling material is fitted with the inner wall of the elastic soft board.

[0009] Preferably, two groups of the buffer tension springs are provided, and the two groups of the buffer tension springs are symmetrically fixed between the inner fixing seat and the connecting column with the inner fixing seat as the center line.

[0013] Compared with the prior art, the utility model provides a tension insulator, which has the following beneficial effects:

[0014] 1. The tension insulator is provided with a locking mechanism. After the insulator is installed, the insulator will be affected by airflow or other external forces in the air and pull the two ends of the insulator. The connecting posts at both ends of the main shell can be pulled outward for a certain distance. The bottom of the connecting post is connected to the inner fixing seat through a buffer spring. The buffer spring provides the function of returning the connecting post to its original position. When the connecting post moves outward, the telescopic shafts on both sides of the connecting post will be squeezed inward, and the telescopic shaft will move forward on the sliding groove through the sliding seat. When the sliding seat moves forward, the pressure spring will be squeezed. This series of mechanisms can prevent the connecting post from directly physically colliding with the main shell when it is pulled outward, causing structural damage, and effectively buffer the excessive force on both ends of the insulator, thereby improving the overall toughness and structural strength of the insulator.

[0015] 2. The tension insulator is provided with an adjustment mechanism. The insulator is generally installed at high altitudes, where it is often affected by the intersection of various air currents. Insulators are mostly made of ceramic or glass products and are easily affected by thermal expansion and contraction. Therefore, a support plate and an elastic soft plate are added to the inner wall of the main shell to support the internal structure of the insulator and cooperate with the filling material to reduce the structural changes of the main shell caused by thermal expansion and contraction, thereby improving the service life of the product.
