Modular unit quick replacement structure of combined type pipe orifice heating auxiliary device

Abstract

The utility model discloses a modular unit quick replacement structure of a combined type pipe orifice heating auxiliary device, which can quickly replace a heating ring, and when the heating ring breaks down or heating rings with different powers need to be replaced according to different pipe orifice specifications, an old ring can be conveniently detached from a mounting seat and a new ring can be conveniently mounted, so that the use is convenient. The whole device does not need to be adjusted or replaced complexly, so that the downtime of equipment is greatly shortened, and the production efficiency is effectively improved. The device has automatic unlocking and locking functions, when a heating ring is installed, a conductive conical block is inserted into a connecting hole, a triangular locking block is pushed to overcome the elastic force of a third spring to slide into a locking hole, and the triangular locking block pops up and is clamped after being in place, so that stable mechanical and electrical connection is guaranteed; during disassembly, the pressing plate is pressed to enable the conductive conical block to descend, the unlocking conical block pushes the triangular locking block to relieve clamping, the pressing plate is loosened, the conductive conical block pops up, automatic unlocking is achieved, and the heating ring is conveniently taken out.
