Button-type mechanical coded lock

Abstract

The invention discloses a button-type mechanical coded lock, and belongs to the technical field of mechanical coded locks. According to the technical scheme, the button-type mechanical coded lock comprises a shell, a top cover for sealing the shell, code buttons and an unlocking button, wherein the code buttons and the unlocking button penetrate through the top cover, the interior of the shell comprises a button stepping mechanism, a comparison unit and an unlocking mechanism, and an unlocking push rod controlled by the unlocking mechanism is arranged on one side face of the shell; the buttonstepping mechanism is driven by the code buttons; the unlocking mechanism is driven by the unlocking button. The button-type mechanical coded lock has the advantages that the button-type mechanical coded lock is suitable for lock cylinders of electronic locks, and compared with a traditional button-type mechanical coded lock, the safety and reliability are obviously improved; compared with a traditional electronic lock, the failure rate is low, and the environmental applicability is high.

Description

technical field [0001] The invention relates to the technical field of mechanical combination locks, in particular to a key-type mechanical combination lock. Background technique [0002] At present, there are many kinds of existing button-type mechanical combination locks, such as the authorized announcement number CN201187187 discloses a button-type mechanical combination lock cylinder, which has the advantages of strong confidentiality, high reliability, no electricity and no keys, etc. Common push-button mechanical combination locks in the world. However, this patent and many existing mechanical combination lock cylinders have potential safety hazards. When pressing the wrong button serial number, the serial number coding block and other interlocking mechanisms will automatically reset. Professionally skilled personnel can judge through experience in various aspects such as sound and strength, and there are certain potential safety hazards in opening the button-type mec...

Problems solved by technology

However, this patent and many existing mechanical combination lock cylinders have potential safety hazards. When pressing the wrong button serial number, the serial number coding block and other interlocking mechanisms will automatically reset. Professionally skilled personnel can judge through experience in various aspects such as sound and strength, and there are certain potential safety hazards in opening the button-type mechanical combination lock with technology.

[0003] Publication No. CN106836982A discloses a button-type mechanical coded lock and a verification method for unlocking it. Only when the password input action is completely completed, is it verified whether the password string for unlocking is correct, and it is impossible to know whether each password is correct during the password input period, which is different from the traditional Compared with the push-button mechanical combination lock, it obviously improves the security and reliability, but it is only suitable for the traditional handle lock, but the handle lock has poor security performance, and generally can only be used as a room door lock.

[0004] The electronic locks that are gradually being used in the market have good confidentiality and complete functions, but special wires need to be reserved before installation, and some doors that are very suitable for specifications are required. The complicated electrical structure leads to a relatively low probability of failure. High, and once the power is cut off, it is still impossible to avoid the key unlocking. In addition, the electronic device is afraid of moisture, strong magnetism, and strong vibration, so it has certain requirements for the use environment. There is no safe and reliable mechanical combination lock for this lock cylinder. match
