Code lock with key

Abstract

The invention discloses a dial lock with a key and the dial lock comprises a lock body and a shackle. Cooperating with each other, a plug and a lock head are arranged in the lock body. The plug is connected flexibly with the lower part of the lock body. The top of the lock head is provided with a lock hole for limiting the shackle and the top of the plug is provided with a promoting block which is outward raised. The bottom of the lock head is a helicoid and the promoting block withstands the helicoid. The plug is turned to facilitate the promoting block to move along the helicoid and the up-and-down movement of the lock head is realized, thereby causing the lock head to be locked up and separated from the shackle. The outer side of the lock head is covered with a return spring. The top of the return spring withstands the inner wall of the lock body and the bottom withstands the lock head. The dial lock can realize the separation of the shackle and the lock body automatically. When using a traditional key to unlock the lock, people can use the key to rotate the plug, the promoting block of the plug is caused to move along the helicoid of the lock head by the lock head under the promoting effect of the restoring force of the return spring and then the lock head moves down relative to the plug, thereby separating from the shackle. The shackle can be rotated freely to achieve the unlocking purpose. The dial lock has a simple structure and convenient and rapid operation.

Description

technical field [0001] The invention relates to a lock, in particular to a coded lock with a key. Background technique [0002] The coded lock with a key includes a lock body and a lock beam. The lock body is provided with a lock head for locking the lock beam. It can adopt two unlocking methods of a password and a traditional key. When the combination wheel is used to unlock the lock, after turning the combination wheel to get the correct password, the lock beam of the combination lock is bounced upwards and separated from the lock head to realize the purpose of unlocking; Then push down the top of the lock head by hand to make it break away from the lock beam, so as to realize the purpose of unlocking. After adopting the traditional key to unlock the lock, it is still necessary to manually separate the lock beam and the lock body, so the operation is cumbersome when using the traditional key to unlock the lock.
