In our daily life, when we move objects or move house, we use many things, but there is one small thing that you will not notice, that is the over-center buckle, which is usually on the belt that secures the goods, so People who noticed are generally rare.
This kind of over-center buckle is a belt used to fix goods during tight transportation. The buckle includes a handle pivotally mounted on a U-shaped body, and the tension band passes through the handle, where it is opening The improved structure includes a lock plate slidably mounted on the main body, the lock plate can be moved between the handle lock and release positions, and there is sufficient space between the lock plate and the handle to allow the handle gap during release.
The buckle of over-center buckle is generally made of flat material and has a structure suitable for withstanding high forces. The buckle works on an off-center principle, so once it is locked, further tension on the belt will keep the buckle locked. When using a buckle, initially, the free end of a belt passes through the buckle and is pulled to absorb slack. The free end is clamped between the upright end of the belt and a part of the buckle to prevent slippage. Next, the handle of the buckle is rotated approximately 180 degrees, which causes the upright part of the belt to wrap around the buckle, thereby putting the belt in tension. When the buckle is about to be thrown, the handle of the buckle turns to an eccentric position, in which position, further tension on the belt locks the buckle more firmly.
However, as far as the existing over-center buckle is concerned, it is definitely difficult to fix the goods, so in general, it is still used with other things, such as cam buckle straps with hooks, which are used in combination. Only the largest diameter can play the role of the over-center buckle, so in general, the over-center buckle will not be used alone.
