Description

TECHNICAL FIELD

[0003] The traditional trailer lock adopts a relatively simple and direct mechanical structure. The spherical lock head is accurately sleeved into the ball cover hook at the front end of the trailer, and this step is the basis of the whole locking, and ensures that the connecting point of the lock and the trailer is stable. Then, the lock rod is sleeved on the trailer rod, and is cleverly clamped with the lock body base, so that the lock body base and the trailer rod are tightly locked, like adding a solid barrier to the trailer, so that others are difficult to tow away the trailer. This way is simple and reliable, and plays an important role for a long time.

[0004] The new type of trailer anti-theft password lock is innovated and upgraded on the basis of the traditional one. After the spherical lock head on the base is inserted into the ball cover hook, the core password locking mechanism starts to play a role. The password locking mechanism includes a password wheel assembly, a movable rod, a lock tongue rod and a series of precise components. When the correct password is input, the correct password position of the password wheel assembly will prompt the movable rod and the lock tongue rod to be unlocked, so that the lock rod can freely approach or move away from the spherical lock head, and the ball cover hook is unlocked. On the contrary, when the wrong password is input, the components are in a locked state, the lock rod cannot be operated, and the trailer is locked.
