1 Inch 25mm*500-800kg Ratchet Buckle Cargo Buckle How to lock and unlock the ratchet mechanism? What are the characteristics of the safety mechanism and tooth design?

Ratchet mechanism locking and unlocking mechanism
The ratchet mechanism of the cargo buckle in the 1 Inch 25mm*500-800kg ratchet buckle usually consists of a ratchet rod and a buckle body that cooperates with it. The ratchet rod is provided with a series of teeth that can be locked with the teeth or serrations in the buckle body. When the ratchet rod is pulled or rotated, the teeth on it will move along the teeth or serrations in the buckle body until it reaches a locked position, at which time the teeth of the ratchet rod are tightly engaged with the teeth or serrations of the buckle body to achieve locking.
When unlocking, it is usually necessary to operate the ratchet rod through a lever or handle to separate the teeth on it from the teeth or serrations of the buckle body. This operation may require a certain amount of force or specific skills to ensure that the ratchet buckle can be safely unlocked.

Safety mechanism to prevent accidental unlocking
Locked position of ratchet bar: When the ratchet bar reaches the locked position, the degree of engagement between the teeth on it and the teeth or serrations of the buckle body will be carefully designed to ensure sufficient locking force to prevent accidental sliding or unlocking.
Additional locking devices: Some ratchet buckles may be equipped with additional locking devices, such as safety pins or locking knobs, which need to be manually released or rotated before unlocking, which increases the difficulty and safety of unlocking.
Material strength: The material selection (such as steel) and manufacturing process of the ratchet buckle will also ensure that it can withstand sufficient tension and pressure during use, reducing accidental unlocking caused by external forces.

Special features of the design of teeth or serrations in the buckle body
Precise tooth pitch and tooth shape: The tooth pitch and tooth shape of the teeth or serrations in the buckle body are precisely designed to ensure a match with the teeth on the ratchet bar. This match not only helps to achieve a secure lock, but also reduces wear and noise.
High-strength materials: The buckle body is usually made of high-strength materials (such as steel) to ensure that it can withstand the tension and pressure transmitted by the ratchet bar. At the same time, the hardness of the material will also be optimized to ensure the wear resistance of the teeth or serrations.
Surface treatment: The surface of the buckle body is usually treated with white zinc plating to improve its corrosion resistance and aesthetics. This treatment also helps to reduce the performance degradation of the teeth or serrations due to oxidation or corrosion during use.
