D-ring is a connection or fixing device with a specific shape and function. The following is a detailed introduction to D-ring products:
1. Definition and naming
D-ring, as the name suggests, is shaped like the English letter "D", hence the name.
2. Application scope
D-rings are widely used in the production of various types of clothing, bags, handbags, shoes and hats, etc., to connect or fix the parts of these products. In addition, D-rings are also used in the field of lifting and hoisting, such as die forging and welding D-rings, which are mainly used in molds, machinery, coal mines, ports and other industries. At the same time, in the design of safety belts, D-rings also play an important role, such as the waist D-rings, front D-rings and back D-rings on the belts, which are used for work positioning or fall braking.
3. Materials and processes
The materials of D-rings mainly include zinc alloy and iron. These two materials are surface treated by polishing, electroplating and other methods to improve their aesthetics and durability. In the field of lifting and hoisting, the material of welded D-rings is usually alloy steel, such as 35CrMo, which is tempered and sprayed on the surface to improve its load-bearing capacity and corrosion resistance.
IV. Types and structures
D-rings for clothing and bags: D-rings processed by zinc alloy are usually closed, while D-rings processed by iron are open. These D-rings are usually fixed to the product by riveting, welding or screw connection.
D-rings for lifting and hoisting: The forged welded D-ring is mainly composed of an integrally forged D-ring and a welded base. A positioning spring can be added inside the welded base to adjust the angle of the D-ring.
D-rings for seat belts: Depending on the design and functional requirements of the seat belt, the D-ring may be located in different positions of the seat belt, such as the waist D-ring, front D-ring and back D-ring on the belt. These D-rings are usually made of high-strength alloy steel or stainless steel to ensure their load-bearing capacity and safety.
5. Precautions
When using D-rings, ensure that their rated loads meet the requirements and avoid overloading.
For D-rings used for lifting and hoisting, their appearance should be regularly checked for defects such as cracks and deformations, and the welding and installation instructions should be strictly followed.
When using D-rings on safety belts, ensure that the safety belts are worn and used correctly, and avoid using a single D-ring or an unqualified D-ring during fall braking.
