Embodiment Construction

[0029] see figure 1 , which is a perspective view of the safe of the present invention. The safe 100 of the present invention includes a cover body 15 and a box body 14 . The cover body 15 is hinged on the box body 14 . A front cover 119 is disposed on the cover body 15 , and a control keyboard 113 is disposed on the front cover 119 . A latch assembly 4 and a key lock cylinder 17 are provided on the front of the box body. When the safe 100 is closed, the safe 100 is locked by the latch assembly 4 . After the latch assembly 4 is disengaged from the cover 14, the safe 100 is opened. There are two latch assemblies 4, arranged left and right respectively. There can also be only one latch assembly 4 . When the emergency key lock cylinder 17 is in the locked position, the latch assembly 4 can be disengaged automatically through the operation of the control keyboard 113 . As an alternative or emergency measure, the safe 100 can also be opened with a keyed lock cylinder 17 . T...

Abstract

The invention provides a safety box. A safety box lid is connected to the safety box in a hinged mode. The safety box is locked through a latch assembly. A nitinol wire is connected with a latch assembly starting device. The latch assembly starting device is connected with the latch assembly. A user opens the safety box by inputting a correct password to a keyboard; after the user inputs the correct password, an electric signal is transmitted to the nitinol wire, so that the nitinol wire is shortened; as the nitinol wire is shortened, the latch assembly starting device opens the latch assembly. Preferably, a key lock is further arranged to control the latch assembly starting device, and the key lock can be used as another way of opening the safety box.

Description

technical field [0001] The invention relates to a safe, in particular to a locking device for the safe. Background technique [0002] Safes are well known in the art. They are primarily used to preserve documents, cash, jewelry and other valuables from fire or theft. Freestanding safes are commonly used in homes or businesses throughout the world. A fireproof safe is a safe that is used to protect its contents from being damaged when subjected to high temperature or fire. [0003] Nitinol wire (also known as muscle wire or memory wire) is a slender alloy wire with shape memory mainly composed of nickel (Ni) and titanium (Ti). The nitinol wire shortens when it receives an electrical signal or is otherwise heated. After the electrical signal disappears or cools, the nitinol wire returns to its original length. [0004] At present, various locking mechanisms have been used on safes. The existing safe mainly has the following two opening methods: one is to key in a passwor...
