Vault door

Abstract

The invention discloses a vault door. The vault door is characterized in that the vault door comprises a door frame, a door leaf mounted on the door frame through a door hinge, a front door lock device installed on the door leaf, and a latch assembly with movement controlled by the front door lock device; a door back lock device used for unlocking behind the door is disposed between the latch assembly and the door front lock device; a relocking device used for limiting the movement of the latch assembly is mounted in the door leaf; the door hinge can adjust the installation height of the vaultdoor through cooperation with a pin and an adjusting bolt. The vault door has the advantages of adjusting the installation height of the vault door directly through the door hinge after a long time use and height deviation, avoiding safety hazards with the door back lock device to allow the person locked behind the door to open the latch, triggering the start up of the relocking device for tempered glass breakage and improving anti-theft and anti-drilling performance of the vault door regardless of where a criminal destroys the door leaf, achieving upper and lower end swap installation of thevault door by using the door hinge to realize clockwise opening or counterclockwise opening, and improving production efficiency.

Description

technical field [0001] The present invention relates to the technical field of vault doors, in particular to a vault door. Background technique [0002] The treasury door is a special protective door for the warehouse area of ​​banks, stock exchanges, gold stores and other industries. Its manufacturing, material and performance requirements far exceed the requirements of anti-theft doors. It is mainly used for anti-theft and anti-drilling. Conventional vault doors are divided into two one-way opening methods: left-hand opening and right-hand opening. It is necessary to distinguish the door-opening methods during production and installation, resulting in low efficiency; Thickness, manufacturing process, etc., lead to the overall thickness of the vault door, which is inconvenient to install. Unlocking and opening the door outside the door, if someone is locked in the door but cannot get in touch with the outside world to open the door, there is a potential safety hazard; in o...

Problems solved by technology

Conventional vault doors are divided into two one-way opening methods: left-hand opening and right-hand opening. It is necessary to distinguish the door-opening methods during production and installation, resulting in low efficiency; Thickness, manufacturing process, etc., lead to the overall thickness of the vault door, which is inconvenient to install. Unlocking and opening the door outside the door, if someone is locked in the door but cannot get in touch with the outside world to open the door, there is a potential safety hazard; in order to improve the anti-theft and anti-drilling performance of the vault door, the existing vault door is generally designed with a relock device, but the existing heavy-duty The structure of the lock device is complex; therefore, it is urgent to design a vault door that can solve the above problems and meet the performance of anti-theft and anti-drilling.
