A mechanical combination lock

Abstract

The invention relates to a device utilizing digital codes for replacing keys for locking and unlocking, and discloses a mechanical coded lock. Operation is simple, safe and reliable, and the mechanical coded lock can replace traditional door locks universally used by existing homes. The mechanical coded lock is composed of a lock body outer side panel, a lock body element bottom plate, a lock body element cover plate and a lock body inner side panel. The lock body outer side panel is provided with an unlocking and locking knob shaft, a code disc and a plurality of hollow and solid code adjusting knob shafts. According to the mechanical coded lock, during locking, the marker lines of the multiple hollow and solid code adjusting knob shafts are firstly aligned to unlocking code number positions arranged on the lock body outer side panel, then the unlocking and locking knob shaft is anticlockwise rotated by about 360 degrees, an upper latch, a middle latch and a lower latch all outwards stretch out of a lock body from the interior of the lock body, then the marker lines of the multiple hollow and solid code adjusting knob shafts and the arranged unlocking code number positions are adjusted to be disorderly so as to prevent unlocking codes from being leaked, the lock is complexly closed, and unlocking operation is opposite to locking operation.

Description

Technical field:

[0001] The invention relates to a device which uses a digital code instead of a key for unlocking and closing the lock, and is simple in operation, safe and reliable. technical background:

[0002] Door lock is an indispensable tool in people's life. It has been handed down from generation to generation for thousands of years. They are all tools to open door locks with different structures and different methods and different types of keys. Even in many countries now, Many different types of mechanical combination locks, electronic combination locks, fingerprint locks, etc. have been invented and manufactured in many fields. Because the mechanical combination lock is a combination structure, the operation is cumbersome, and if you are a little careless, the code adjustment knob will miss it. Once the set password number position is missed, you have to start all over again. Their code adjustment operation procedures must be operated according to the set direct...

Embodiment 1

[0025] Such as figure 1 , figure 2 , Figure 4 The locking and safety protection functions of the mechanical combination lock, when closing the lock, first align the marking lines of a plurality of hollow and solid coding knob shafts (103) with the unlocking password set on the outer side panel of the lock. Digital position, and then rotate the lock knob shaft (202) counterclockwise for about 360 degrees, which will drive the hollow shaft for opening and closing the lock (431), the control panel for opening and closing the lock (428), the opening and closing of the lock The gear part (430), the opening and closing latches are connected to the gear part (426) to rotate together;

[0026] One end of the opening and closing latch control connector (425) is rotated to the opening and closing latch control disc ( The outer edge of 428) is about a circle 360 ​​degrees, and then gets back to the bottom of the opening and closing latch control groove (429). 1. Close the change of...

[0029] Such as figure 1 , figure 2 , Figure 5 The unlocking function of the mechanical combination lock, when unlocking, when any one of the plurality of hollow and solid coding knob shaft parts (103) is rotated arbitrarily, the corresponding plurality of coding gears and shafts (505) will One of them also rotates thereupon, drives the corresponding password gear in multiple password gears (519) simultaneously, and the corresponding password disk rotation in multiple password disks (517), because the edges of multiple code disks (517) respectively A password positioning slot (518) is provided;

[0030] When the unlocking password number of input is correct, the password positioning slots (518) of a plurality of password disks (517) on the plurality of password disks (517) correspond to a straight line, and then rotate clockwise to open and close the lock knob shaft (202) about a circle of 360 When the degree is high, it will drive the hollow shaft for opening and closing ...

[0032] Such as figure 1 , figure 2 , Figure 6 1. The indoor unlocking and locking functions of the mechanical combination lock, when the lock is opened, before the owner enters the room, the multiple hollow and solid coding knob shaft parts (103) in the outer panel (101) must be turned ), the set unlock password is messed up to prevent the password from leaking;

[0033]In this state, one end of the code disk password locator (622) is just at the outer edge of a plurality of code disks (617), and one end of the opening and closing lock bolt control connector (625) contacts on the code disk code locator ( 622) on the corresponding position, the other end is in contact with the bottom of the control groove (629) on the open and close lock bolt control panel (628), no matter how to rotate the open and close lock knob shaft (202) outdoors, the upper lock bolt ( 613), middle latch (615), lower latch (614), all can not stretch out lock body;
