Fireproof safe against high temperature deformation

Abstract

The invention relates to a fireproof safety box for preventing high-temperature deformation. The fireproof safety box comprises a box body formed by sleeving a metal outer shell and a plastic inner shell; a filling hole is formed in the outer surface of the metal outer shell; and a box body filling space for filling a thermal insulation filler is formed between each outer surface of the plastic inner shell and each inner surface of the metal outer shell. The fireproof safety box is characterized in that a first latch head hole is formed in the side wall of the plastic inner shell; a reinforcing plate is arranged on the outer side of the first latch head hole; the reinforcing plate has a horizontal wall and a vertical wall; the vertical wall is fixed on the outer surface of the plastic inner shell, and is provided with a second latch head hole opposite to the first latch head hole; and the horizontal wall is embedded in the thermal insulation filler. Compared with the prior art, the fireproof safety box has the following advantages: the condition of easy pullout of safety box latch heads by external force due to deformation of the plastic inner shell by high temperature is prevented; and finally, the purpose of improving the use safety of the safety box is achieved.

Description

technical field [0001] The invention relates to a safe structure with a plastic inner shell, in particular to a fireproof safe that prevents high-temperature deformation. Background technique [0002] A fireproof safe is a safe with fireproof and heat insulation functions. The main difference between it and ordinary safes is that the wall of the box is filled with a fireproof and heat insulation layer. Specifically, the box includes a box shell with a packing cavity. The filling chamber is filled with fireproof and heat insulating materials. When a fire breaks out, due to the effect of the fire-proof and heat-insulating layer, the temperature in the safe is controlled within a certain period of time to the extent that the objects in the safe will not burn, so as to reduce losses. [0003] Both the outer shell and the inner shell of a traditional safe are made by bending and welding metal plates, which has high production costs and complicated processes. Since the inner she...

[0003] The outer and inner shells of traditional safes are made by bending and welding metal plates, which has high production costs and complicated processes

Since the inner shell of the safe is located inside the safe, illegal elements cannot directly destroy it, so more and more safe inner shells use an integrally formed plastic inner shell, thereby saving costs and simplifying the production process. However, the outer shell of the safe is located outside the safe and needs to be protected. The contents of the safe, so it is still made of strong metal material

[0004] When this type of safe is in a high temperature environment for a long time, the plastic material of the inner shell is easy to soften and deform. The bolt hole, and then the door of the safe is opened, and the property in the safe is stolen
