The invention provides a combination lock, and aims to solve the problem that an existing combination lock is liable to damage. The combination lock comprises a bottom frame, a lock hook, a bottom shell, an upper cover, a movable piece, a reset spring and a cryptographic device, wherein a first arc-shaped groove is formed in the bottom shell; the movable piece is fixedly connected with a stop block; a stop rod which is used for preventing the stop block from rotating is fixedly connected with the bottom frame; the stop rod is arranged in the first arc-shaped groove in a penetrating manner; when the movable piece is positioned at a reset position, the stop block is positioned on the outer side of the first arc-shaped groove; after the cryptographic device pushes the movable piece to compress the reset spring, the stop block is positioned above the first arc-shaped groove; a second arc-shaped groove which is matched with the lock hook and is communicated with the inlet of the lock hook is formed in the bottom shell. According to the combination lock, the lock hook is connected with the bottom cover, the bottom shell is hooked with the lock hook after rotating, and the bottom shell is fixed by adjusting the cryptographic device, so that a box is locked; the combination lock is compact in structure and easy to operate; the lock hook is not connected with an internal structure controlled by the cryptographic device, and the internal structure of the combination lock cannot be damaged by the lock hook because of tensile force; therefore, the service life is prolonged.
Description
technical field [0001] The invention relates to a combination lock. Background technique [0002] In order to prevent things from being lost in the trolley case, coded locks are often provided on the trolley case; however, the existing coded locks are weak in structure and easy to damage the case; due to the collision between the box body and the case cover when it is closed, the coded lock is easily damaged , reduce the service life of combination lock; because the internal structure of combination lock is too simple, it is easy to be cracked and the security performance is lower. Contents of the invention [0003] The invention provides a coded lock, aiming at solving the problem that the existing coded locks are easy to be damaged. [0004] In order to solve the above technical problems, the present invention is realized through the following technical solutions: a coded lock, comprising a bottom frame fixedly connected to the box body, a lock hook fixedly connected to...
