¿Cuál es la estructura de un candado de latón con llave cuadrada?

Cuerpo de cerradura (carcasa de latón)

el candado de latón con llave cuadrada El cuerpo es la estructura estructural principal del candado de latón con llave cuadrada. Por lo general, está hecho de latón macizo o una aleación de latón, se forma mediante fundición o forja y luego se mecaniza hasta alcanzar dimensiones precisas.

Función:

el primary function of the lock body is to serve as the load-bearing and protective enclosure for all internal components. It provides the physical strength required to resist pulling, prying, and impact forces. Brass is selected because it offers good resistance to corrosion, making the padlock suitable for indoor and outdoor environments. The lock body also defines the internal cavities that guide the movement of the locking core, springs, and locking mechanism. In addition, it forms the base to which the shackle is attached and locked.

Grillete (arco de bloqueo en forma de U)

el shackle is the U-shaped metal loop that passes through the object being locked, such as a chain link, latch, or hasp. It is usually made of hardened steel rather than brass to improve resistance to cutting.

Función:

el function of the shackle is to form the physical locking connection between the padlock and the secured object. When the padlock is closed, one or both ends of the shackle are locked inside the brass body. The shackle must withstand tensile force, twisting force, and cutting attempts. One end of the shackle is often fixed inside the body, while the other end is movable and engages with the internal locking mechanism. Once locked, the shackle transfers external pulling forces directly into the lock body and internal locking components.

Cilindro de llave cuadrada (núcleo de cerradura)

el square key cylinder, also referred to as the core or plug, is the central rotating component into which the square key is inserted. Its outer shape matches the key profile, usually with a square or rectangular cross-section.

Función:

el function of the square key cylinder is to convert the rotational movement of the key into mechanical action that controls the locking and unlocking process. When the correct key is inserted, it aligns the internal locking elements so that the cylinder can rotate. This rotation activates the cam or locking pawl that releases or captures the shackle. Without the correct key profile, the cylinder remains blocked and cannot turn, preventing unlocking.

Clavijas, vasos o placas de bloqueo

Dentro del cilindro de llave cuadrada hay pasadores de llave, fiadores o placas de bloqueo planas, según el diseño interno específico. Estos componentes interactúan directamente con la forma de la llave cuadrada.

Función:

el function of these internal locking elements is to verify the key profile. When the correct key is inserted, the contact surfaces of the key push these elements into precise alignment. Once properly aligned, the cylinder is allowed to rotate. If the wrong key is inserted, the blocking elements remain misaligned and mechanically prevent rotation. This forms the basic security principle of the square key locking mechanism.

Resortes de retorno

Detrás de los pasadores de llave o placas de bloqueo dentro del cilindro se instalan pequeños resortes metálicos. Estos resortes suelen estar hechos de acero para resortes o acero inoxidable.

Función:

el springs provide the restoring force that pushes the blocking elements back into their default locked positions when the key is removed. This ensures that the lock automatically resets to the locked state after each operation. The consistent pressure from the springs also contributes to stable key feedback during insertion and rotation, allowing smooth but controlled movement of the lock core.

Leva o trinquete de bloqueo

el cam or locking pawl is a rotating metal component attached to the rear of the cylinder. It directly interacts with the shackle locking notch.

Función:

Cuando la llave hace girar el cilindro, la leva gira con él. En la dirección de desbloqueo, la leva se aleja de la muesca del grillete, permitiendo que el extremo móvil del grillete se suelte hacia arriba. En la dirección de bloqueo, la leva gira hacia la muesca, capturando el grillete dentro del cuerpo. Esta parte sirve como vínculo mecánico directo entre la rotación de la llave y el movimiento del grillete.

Muesca de bloqueo del grillete y mecanismo de retención

En el propio grillete, especialmente en el extremo móvil, hay una muesca o ranura de bloqueo que engrana con la leva interna o el trinquete de bloqueo.

Función:

el function of this notch is to provide a defined engagement point where the locking mechanism can hold the shackle securely in the closed position. When locked, the cam presses into this notch, preventing any upward movement of the shackle. Only when the cam rotates out of this position can the shackle be released. This interface between the shackle and the locking mechanism is essential for mechanical holding strength.
