Description

Technical Field

[0001] The utility model relates to the technical field of turnbuckles, in particular to a turnbuckle for ships with an anti-falling structure. Background Art

[0002] The turnbuckle is a connection fitting with left-handed and right-handed threads at both ends to adjust the connection length. The turnbuckle uses a lead screw to expand and contract, and can adjust the tightness of the wire rope. It can be used to bundle components during transportation and loosen them during installation and correction. It consists of an adjustment rod with left-handed and right-handed threads, a nut and a pull rod. The adjustment rod is also fixed with an anti-theft and anti-loosening device composed of a cover plate, a fixing plate, and a guide plate connected together by anti-theft and anti-loosening bolts. When in use, a special matching sleeve must be used to unscrew the anti-theft and anti-loosening bolts, which has a good anti-theft effect and is safe and reliable. After the anti-theft and anti-loosening device is disassembled, it does not need to be taken down. The ring guide plate on it can be used to slide along the pull rod, and it can be adjusted and operated by moving a distance, so it is easy to use. It has a simple structure, is easy to process, has low cost, and is highly practical. It is particularly suitable for power lines, especially as a positioning device for high-voltage iron tower pull rods.

[0003] In the field of ships, turnbuckles are also commonly used for adjustable connection on both sides, but the existing turnbuckles used in this field do not have any fixing, which makes them easy to fall off and have poor reliability. Utility Model Content
