Description

Technical Field

[0001] The utility model relates to the technical field of wire tensioners, in particular to a one-code intermediate wire tensioner. Background Art

[0002] A cable tensioner is a power facility device used to fix and tighten cables. It can be divided into top cable tensioners, middle cable tensioners and terminal cable tensioners. The middle cable tensioner is mainly used to clamp and fix the middle section of the cable and the insulator.

However, the sealing between the outer cover and the tensioner is poor and there is a large gap. Rainwater is still likely to contact the nut and the screw, causing rust, making it difficult to disassemble later. Utility Model Content

A protective sleeve 3 is installed on the outside of the J-shaped screw 7. The protective sleeve 3 is used to protect one end of the J-shaped screw 7 to avoid rust caused by contact with rainwater. A groove 14 is provided at one end of the protective sleeve 3. A first sealing sleeve 15 is installed inside the groove 14. The first sealing sleeve 15 is used to improve the sealing between the nut 4 and the protective sleeve 3 to avoid rainwater from contacting the J-shaped screw 7 through the gap between the nut 4 and the protective sleeve 3.

[0019] A buckle 9 is fixedly connected to the outer side of the top plate 8 , and a slot 12 matching with the buckle 9 is provided on the outer cover 5 . The buckle 9 and the slot 12 cooperate to fix the outer cover 5 to the outer side of the top plate 8 .

[0020] Among them, the sealing strip 13, the second sealing sleeve 17 and the first sealing sleeve 15 are made of rubber material. Rubber has good elasticity, so it can achieve a good sealing effect. It also has excellent wear resistance and corrosion resistance and can be used for a long time in various harsh environments.

[0021] Among them, a through hole 10 is penetrated on the top plate 8, and the through hole 10 can facilitate the J-shaped screw 7 to pass through the top plate 8, and also facilitate part of the nut 4 to pass through the top plate 8. A second sealing sleeve 17 is provided inside the through hole 10, and the second sealing sleeve 17 is used to improve the sealing between the top plate 8 and the nut 4, and prevent rainwater from entering between the top plate 8 and the outer cover 5 along the nut 4.
