What is a turnbuckle definition?

Publish Time: 2022-10-14     Origin: Site

A turnbuckle, also known as a stretching screw or bottle screw, is a device for tightening a rod or stay that typically consists of a link with screw threads at both ends that is turned to bring the ends closer together. It is commonly made up of two threaded eye bolts, one screwed into each end of a small metal frame and the other with a right-hand thread. The tension can be adjusted by rotating the frame, causing both eye bolts to screw in or out at the same time, without twisting the eye bolts or attached cables.

What is turnbuckle used for?

1. Turnbuckles are most commonly used in high-tension applications; their mass can range from about ten grams for thin cable used in a garden fence to thousands of kilograms for structural elements in buildings and suspension bridges.

2. Turnbuckles were used in aircraft construction, particularly in the early days of aviation. Historically, turnbuckles were used to adjust the tension on structural wires bracing the wings of biplanes. Turnbuckles are also commonly used in flight control systems on flexible cables. They are secured with lockwire or specially designed wire clips in both cases to prevent them from turning and losing tension due to vibration.

3. Turnbuckles are used to tighten the rigging and lashings on a ship. In this context, this device is also known as a bottlescrew.

4. Turnbuckles are commonly used to tension the ropes in professional wrestling and boxing rings, where they serve as the connection between the ring ropes and the ring posts. Instead of the usual bare metal, the turnbuckles here are padded to protect participants and staff.

5. Turnbuckles are also used in professional wrestling, where participants frequently use them as part of their offensive moveset.

6. Turnbuckles are used in nearly every aspect of rigging in the entertainment industry, including theatre, film, and live concert performances. Turnbuckles are more commonly used in entertainment rigging to make minor adjustments to line lengths. In most cases, this is done to make a flown unit sit parallel to the stage. Another application for a turnbuckle is for making minor height or angle adjustments.

7. Turnbuckles are used in piping systems to provide minor adjustments for inconsistencies in the field. This also allows for a low resistance when transferring the load to the support components.
