Camlock (e.g. camlock a type, stainless steel camlock, ss camlock coupling), simply put, is the use of an 'eccentric disc' in the process of rotating the pressure generated by the familiar "The principle of camlock coupling is similar to that of door locks and bicycle quick release levers.

Let's take a common door lock at home as an example to understand the principle of camlock.

When you look carefully inside the door lock, you will find that there is a piece of iron with a bevelled surface, this piece of iron here is equivalent to what we call 'cam'. It may seem ordinary, but it plays a key role in the opening and closing process of the door lock. Usually we go home, habitually hold the door handle gently twist. Behind this simple action, there is a wonderful mechanical principle. With the rotation of the handle, and the handle is connected to the lock tongue will also follow the rotation of a specific angle. At this time, the lock tongue quickly 'squeezed' into the door frame pre-set groove, the lock tongue into the door will be firmly stuck, played a security role. When we want to go out, we just need to turn the handle in the opposite direction. At this time, the lock tongue from the slot in the door frame retracted. The door opens easily without the latch in the way.

The camlock is usually an 'eccentric circle', which is often referred to as thicker on one side and thinner on the other. As the camlock begins to rotate, the thick side gradually moves into contact with the two objects to be secured. At this point, the thick side 'pins' the two objects tightly together. When loosened. As the camlock continues to rotate, the thin side turns over. The thin side, due to its thin thickness, is unable to provide as much squeezing pressure as the thick side, and the pressure disappears.
