Novel three-way catalyst heat insulation mechanism

The utility model relates to the technical field of automobile three-way catalytic converters, in particular to a novel three-way catalytic converter heat insulation mechanism, which is characterized in that a plurality of connecting blocks are fixedly connected to two sides of two shells, the connecting blocks are oppositely arranged, and the connecting blocks are fixedly connected through fixing bolts. According to the novel three-way catalytic converter heat insulation mechanism, the two separated heat insulation layers at the front end can be pushed to be attached to the outer wall of a three-way catalytic converter through the fixing block, meanwhile, the supporting block separates the baffle between the shell and the three-way catalytic converter to form blocking, and a threaded plug can be screwed to open a sealing groove to inject cold water; and cold water in the sealing groove can block heat conducted through the connecting pipe, and the heat insulation effect of the novel three-way catalyst heat in
