JIS Frame Type Turnbuckle is a unique type of turnbuckle produced in accordance with the Japanese Industrial Standard (JIS), which is characterized by its frame-type structural design. This type of turnbuckle is mainly composed of a left-handed and right-handed threaded rod, a frame-shaped adjustment body in the middle, and connecting end accessories. The design of the frame-shaped adjustment body makes it more stable during the adjustment process, and it can better cope with lateral forces compared to ordinary turnbuckles. In terms of materials, common ones are carbon steel (rust-proof surface) and stainless steel (such as SUS304, SUS316) to meet the use requirements in different environments. The specifications are generally distinguished by the diameter of the threaded rod and the adjustment stroke, from smaller specifications for tension adjustment of fine equipment to larger specifications for industrial facilities. It covers a wide range and is widely used in mechanical assembly, building assistance, and some scenarios with specific requirements for installation space and adjustment accuracy.

Comply with JIS standards, reliable quality: Strictly follow the Japanese industrial standards for production, all parameters and performance indicators are strictly controlled, for example, in terms of dimensional accuracy, the thread processing accuracy meets the tolerance range specified by JIS, ensuring the stability and consistency of product quality, and can be used with confidence in various application scenarios.
Frame structure, strong stability: The frame-shaped adjustment body in the middle is its core design highlight. Compared with traditional straight-barreled turnbuckles, the frame structure can effectively enhance the overall lateral force resistance. When subjected to tension or pressure from the side, it can still maintain a stable adjustment function, and is not prone to deformation or damage. It is especially suitable for occasions with limited installation space and complex forces.
Various materials, suitable for different environments: Carbon steel materials are usually treated with rust prevention such as galvanizing and nickel plating. They have good rust resistance in general indoor environments or dry industrial environments and can be used for a long time; SUS304 stainless steel materials are suitable for outdoor environments with a certain humidity or ordinary corrosive environments, and can effectively resist atmospheric corrosion; and SUS316 stainless steel contains molybdenum elements, which has more outstanding resistance to salt spray corrosion and acid and alkali resistance. It can be used in coastal areas or chemical-related environments to meet the needs of corrosion resistance in different scenarios.
Precise adjustment and convenient operation: By rotating the frame-shaped adjustment body, the synchronous extension and retraction of the threaded rods at both ends can be achieved, and the adjustment process is smooth and smooth. The surface of the adjustment body is usually designed with easy-to-operate patterns or interfaces, which can be adapted to common wrench tools. The operation is simple and easy to understand, and the adjustment accuracy can meet the needs of most industrial and civil scenarios. For example, in some mechanical transmission systems that require precise tension, the tension value can be accurately adjusted to the appropriate value.
Flexible connection form, good adaptability: The connection end accessories at both ends are of various forms, including hook type, ring type, fork type, etc., which can be selected according to the actual use scenario and the connection object. These connection forms can be quickly connected with various standard or non-standard connectors, ropes, etc., without the need for complex adapters, which greatly improves the installation efficiency and convenience of use.
Mechanical manufacturing and assembly: During the installation and commissioning of machine tools, it is used to adjust the tension of transmission belts and chains to ensure smooth operation of the equipment and accurate power transmission; in the equipment assembly of some automated production lines, it is used to adjust the tension of various support and traction ropes to ensure the stability and reliability of the equipment during operation.
Construction and interior decoration: In construction, for the connection and fixation of some small building structures, the tension of the connecting ropes or cables can be adjusted by JIS frame-type turnbuckles to enhance the stability of the structure; in the field of interior decoration, when used to hang heavy objects such as lamps and decorations, the tightness of the hanging ropes is adjusted to ensure the safety and horizontality of the hanging objects.
Ships and water facilities: On small ships, it is used to adjust the tension of the cables to ensure the stability of the ships when docked; in the construction and maintenance of water facilities such as floating bridges and piers, the rope tension of the connecting parts is adjusted to ensure the structural safety of the facilities under the action of external forces such as water flow, wind and waves.
Agricultural and horticultural equipment: In the construction of agricultural greenhouses, the tension of the ropes of the greenhouse frame is adjusted to enhance the wind resistance of the greenhouse; some rope-type support structures and hanging planting devices in horticultural landscapes can adjust the rope tension through this type of flower basket screw to meet different planting and landscape design needs.
Q1: How to choose the appropriate JIS frame-type turnbuckle screw specifications?
A: First, the diameter of the threaded rod should be determined according to the stress conditions in the actual use scenario. The greater the stress, the larger the required threaded rod diameter should be. For example, in a construction scenario that is subjected to greater tension, it may be necessary to select a larger diameter specification. Secondly, the adjustment stroke should be determined according to the length range that needs to be adjusted. The adjustment stroke should be slightly larger than the maximum adjustment amount actually required. It is generally recommended to reserve a 10%-20% margin to ensure sufficient adjustment space. At the same time, the size of the installation space should also be considered to select a frame-shaped adjustment body of appropriate size to avoid installation difficulties due to space limitations.
Q3: What should be paid attention to during installation?
A: Before installation, check whether the appearance of the turnbuckle screw is damaged and whether the thread is smooth. During the installation process, ensure that the connection at both ends is firm and reliable, and select the appropriate connection method according to the connection form. For example, for hook-type connections, ensure that the hook is completely hooked and not easy to fall off, and for ring-type connections, ensure that the pin is installed in place and fixed. When adjusting the tension, the adjusting body should be rotated gradually to avoid over-adjustment at one time. At the same time, pay attention to the stress of the connecting parts to ensure that the entire connection system is evenly stressed. After installation, check again whether the connecting parts are tightened and whether the adjusting body is in the appropriate adjustment position.
Q3: What should I do if the frame-shaped adjusting body is found to be deformed during use?
A: If the frame-shaped adjusting body is found to be slightly deformed, first check whether the stress in the use scenario exceeds the rated load capacity of the basket screw of this specification. If the deformation is caused by overload, stop using it immediately and replace it with a larger basket screw with a stronger load capacity. If the deformation is more serious, such as obvious distortion and cracks in the frame, a new basket screw must be replaced immediately, because the deformed adjusting body may not be able to perform the adjustment function normally, and there is a risk of breaking when the force continues to be applied, which will pose a serious threat to the safety of the entire connection system.
