We all know that if you do not fix the goods when moving the goods, many of them may cause some damage to the goods. Especially for some relatively large or expensive items, then the tensioner is very important at this time. As a very important part of the tensioner, the over center buckle  is of course essential.

The over center buckle is used to connect the belt used to bind the cargo of the vehicle. The buckle is made of flat material and has a structure suitable for withstanding high compressive forces, for example when it is applied to it when a loaded vehicle passes by. 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 about 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 lock the buckle more firmly. A safety lock is provided to prevent accidental opening of the buckle when the goods are transferred.

The above is the principle of the center buckle. For more details, please visit cam buckle straps with hooks .
