Abstract

The utility model discloses a mechanical padlock with secret codes, mainly comprising a lock body, a lock beam, a lock bolt, code wheels, etc. The mechanical padlock with secret codes is characterized in that the interior of the lock body is provided with a group of code wheels whose interior is a step-shaped circular ring; the wall of each step shaped circular ring is provided with a keyway; a cylinder on one end of the lock beam is erectly provided with 3-5 keys, and the lock beam is inserted into the lock body and is sealed. When the mechanical padlock with codes is unlocked, the digitals of the codes need adjusting well, and the mechanical padlock with secret code is unlocked through a key. The mechanical padlock with secret code has confidentiality and safety.

Description

Mechanism lock with puzzle code

The utility model relates to a kind of Mechanical ring latch with password.

The padlock of selling on the existing market, the overwhelming majority is not with password only to use the padlock of private key, a rotating lock core is arranged in its lock body, insert lock core and rotation with special bitting during unlatching, make the key on the lock core top drive the dead bolt withdrawal, unclamp lock bridge, make it to open, the rotation of lock core is controlled by snap and pellet shot from a slingshot.Because this lock does not have other security insurance measure, just makes any people who chooses key all lock can be opened.

It is a kind of as be unfamiliar with structural principle of the present invention that the purpose of this utility model is to provide, even if hold also the do not open Mechanical ring latch of band password of key, to improve the security insurance of lock.

Goal of the invention of the present utility model is achieved in that

Basic structure: form by lock body, lock bridge, lock core, dead bolt, spring and cipher wheel etc., be characterized in one group of garden of overlapping installation ring structure cipher wheel in the lock body lockhole corresponding with the lock bridge free end, it in it hole, stairstepping garden, on the stairstepping inner hole wall, have a keyway, its external surface uniform digital 0～9, hold up on the cylinder of the end in lock bridge inserts the cipher wheel lockhole and arrange 3～5 keys, its number equates with the cipher wheel number.Key is inserted to be had in the cipher wheel hole of keyway, rotate any one cipher wheel, make it dislocation, just form locking device, and the locking of the other end of lock bridge and lock body still adopts the dead bolt that uses at present to combine the formation locking device with lock tongue slot on the lock bridge.When opening this lock with key, even dead bolt unclamps lock bridge, lock can not leave, and also must align one group of cipher wheel, and making the groove in the cipher wheel just in time is the significant digits of its external surface, and the lock bridge of this lock just is totally released and upsprings, and finishes unlocking mechanism.

Owing to adopted the coded lock locking structure on the basis of traditional locks, and cipher wheel is 3～5, and is therefore heavy and probability is little, is difficult for decoding, has confidentiality, safe and reliable.

The front section view that Fig. 1 opens for the utility model lock bridge.

Be further described below in conjunction with embodiment:

As shown in Figure 1, the utility model mainly is made up of lock body 1, lock bridge 2, lock core 3, dead bolt 4 and cipher wheel 5 etc., the weak point of lock bridge 2 props up the end cylinder and holds up four protruding keys 6 of arrangement, in lock body 1 corresponding lock bridge key one group of four cipher wheel 5 of partly packing into, all have a keyway on the stepped inner hole wall of each cipher wheel, its external surface has 0～9 numeral, the external surface significant digits of supposing the keyway correspondence are 1234, lock bridge 2 is inserted in the lock body, rotate any one cipher wheel, make it dislocation, just form locking device.Open this lock, earlier to 1234 of good cipher wheel, using key rotation lock core, lock bridge just unclamps upsprings.

Claims

1, a kind of Mechanical ring latch with password, it comprises lock body 1, lock bridge 2, lock core 3, dead bolt 4, it is characterized in that one group of garden of overlapping installation ring structure cipher wheel 5 in the lockhole corresponding on the lock body 1 with lock bridge 2 free ends, it in it hole, stepped garden, on stepped inner hole wall, have a keyway, external surface is uniform digital 0～9, holds up on the end cylinder that lock bridge 2 inserts in the cipher wheel lockholes and arranges 3～5 protruding keys 6.
