Problems solved by technology

The second is to prevent technical opening. The ability of ordinary mechanical locks to prevent technical opening is very poor.
[0005] First, the open lock cylinder is generally easy to be blocked or even damaged by children or other unruly persons who have failed to enter the door;
[0006] Second, it is very easy for unruly personnel to pass through the hole of the lock cylinder and use a special tool to pick the lock or configure a key to open the door

Embodiment 1

[0040] 2 codes are set on the combination lock mechanism (2) prepared according to the above-mentioned technical scheme, and 2 blades one (11) and two blades (12) are set at the same time.

Embodiment 2

[0042] Add 3 codes on the password lock body mechanism (2) prepared by the above-mentioned technical scheme, and increase 3 blades simultaneously.

Embodiment 3

[0044] The combination lock body mechanism (2) prepared according to the above technical scheme adds 4 to 6 passwords and 4 to 6 blades at the same time.

[0045] Working principle of the present invention: take embodiment 1 as an example, when closing the door, arbitrarily rotate the dial to a certain number, and the combination lock protection lock cylinder works. Since the connecting piece of the combination lock mechanism is held up by the blades and the baffle cannot move upward, the baffle will block the key hole set on the panel, so that the lock cylinder hole is always sealed, and the key cannot be inserted into the lock. core, the door cannot be opened. Twist the dial, when blade 1 and blade 2 rotate to a certain value (0-9) respectively, the direction of the concave opening is the same, and when the opening is facing the connecting piece, move the pin upward, and the baffle moves upward. Only when the hole of the lock cylinder is exposed, insert the key into the loc...

Abstract

The invention discloses a protective coded lock specifically comprising a panel, a coded lock mechanism and a main lock mechanism, wherein a pin slippery hole and a key through hole are formed in the panel, and the coded lock mechanism comprises a handle, a dial, blades, a baffle and the like. When the lock body works, the dial is twisted to ensure that a blade 1 and a blade 2 rotate to (0-9) certain data respectively and consistent directions of concave openings, and when the openings face towards a connecting piece, a pin 3 is moved upwards to expose a lock core hole, and then a key is inserted into a lock core to open a door; and through the coded lock mechanism, the baffle is moved away from the lock core hole, and then the key is used for opening the door. Otherwise, when the opening of any one of the blades does not face towards the connecting piece, and the key is arbitrarily rotated to a certain number, the connecting piece is pressed by the blades, the baffle can not move upwards, the lock core hole is always closed, and the key can not inserted into lock core, so that the door can not be opened. The protective coded lock is a closed device for protecting the lock core, and is strong in protective property, safe, simple and quick, and superior in quality.

Description

technical field [0001] The invention belongs to a functional lock body, in particular to a protective combination lock. technical background [0002] As a security product, door locks must be safe and stable. Safety can be measured from two aspects: one is resistance to vandalism, pranks and deliberate violent damage such as prying and drilling. The 2nd, prevent technical opening, the anti-technical opening ability of common mechanical lock is very poor. Regardless of the mechanical lock of that structure, it can be opened by other means. As a door lock, its stability is also very important. Sometimes, due to the abnormality of the stability of the door lock, the door lock often fails to open the door when it should be opened, and cannot close the door when it should be closed. Cause a lot of trouble for people. [0003] At present, most of the home and office fields use ordinary door locks that use keys to open the door locks. This kind of door lock is mainly composed ...
