Abstract

The invention relates to a hinge for a blast-resistant door. The hinge for the blast-resistant door comprises a hinge lower leaf and a hinge upper leaf which are hinged by a hinge shaft, wherein a shaft hole is formed in the hinge upper leaf; a bearing cavity which is coaxial with the shaft hole is formed in the hinge lower leaf; a bearing is arranged in the bearing cavity; and the two ends of the hinge shaft are arranged in the shaft hole and the bearing correspondingly. The hinge for the blast-resistant door is provided with the bearing, so the hinge for the blast-resistant door has the advantages of high bearing capacity, high blast resistance, rotation flexibility and insusceptibility to damage, and solves the technical problems that the hinges for doors in the fields of petrochemistry, nuclear power, military and blast have high load performance and blast resistance.

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 ...
