Abstract

The present invention discloses a plug-in type electrical heating tube which comprises an electrical heating tube body. The outer surface of the electrical heating tube body is sleeved with a casing; the outer surface of the casing is sleeved with a sleeve; the electrical heating tube body is sleeved with a first fixed ring and a second fixed ring; the first fixed ring and the second fixed ring are respectively clamped at both ends of the casing; and a plurality of jacks are formed at the end parts of the electrical heating tube body. The plug-in type electrical heating tube is convenient to externally connect with a power supply by the electrical heating tube body, enables the electrical heating tube body to be powered on and generate heat by the power supply, can be plugged with an electrical heating wire by the jacks, so that a heat source can be led out by the electrical heating wire.

Description

Technical field [0001] The invention relates to an electric heating tube, in particular to a plug-in electric heating tube. Background technique [0002] The electric heating tube is a metal tube as the shell, and the spiral electric heating alloy wire is evenly distributed along the central axis of the tube. The gap is filled and compacted with magnesia sand with good insulation and thermal conductivity. The two ends of the tube are sealed with silica gel. This kind of metal armored heating element It can heat air, metal molds and various liquids. The existing electric heating tube does not have the function of guiding the heat source and is inconvenient to use. Summary of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a convenient external power supply through the electric heating tube body, the electric heating tube body is energized to generate heat through the power supply, and the electric heati...
