Fire sprinkler sealing assembly

The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting spray head sealing assembly which comprises a connecting seat used for being connected with a spray head, the connecting seat is provided with a water through hole used for being communicated with the spray head, the connecting seat is further provided with a sealing seat used for sealing the water through hole, and the sealing seat is connected with a thermosensitive element in an abutting mode. And an elastic piece is arranged between the thermosensitive element and the sealing seat. Due to the fact that the elastic piece is arranged between the thermosensitive element and the sealing seat, when the sealing seat, the thermosensitive element and other sealing assemblies generate elastic and plastic deformation, the elastic piece can compensate deformation of the sealing assemblies through the elasticity of the elastic piece, and therefore the sealing performance of the sealing assemblies is ensured.
