Description

technical field

[0001] The invention relates to a hinge, in particular to a hinge for an anti-blast door. Background technique

[0002] At present, the door hinges on the market are mostly made of thin stainless steel, including the upper and lower pages connected by hinge shafts, which are mostly used in civil fields, but in petrochemical, nuclear power and explosion-hazardous fields, this kind of hinge is very important. Very thin and easily damaged. Contents of the invention

[0003] The present invention aims at the above-mentioned problem that the existing hinges are easy to be damaged, and provides a hinge for an anti-blast door, which has a large load capacity and strong anti-blast performance.

[0004] According to the technical solution of the present invention: a hinge for an anti-blast door, comprising a hinge lower page and a hinge upper page hinged by a hinge shaft, the hinge upper page is provided with a shaft hole, and the hinge lower page is provided with ...
