Detailed description of the invention
Fig. 1 is triangle magnesium pipe planar structure schematic diagram of the embodiment of the present invention；
Fig. 2 is the tool view of Fig. 1；
Fig. 3 is the bottom view of Fig. 1.
Specific embodiment
As shown, a kind of triangle magnesium pipe, is in the magnesium pipe main body 1 of equilateral triangle including section, has inside magnesium pipe main body 1
The spiral resistance wire shape of the cylindrical hollow inner cavity 2 for thering is front and back to penetrate through, magnesium pipe main body hollow cavity 2 and electric heating tube, ruler
It is very little to be adapted；Magnesium pipe main body is set between electric heating tube and resistance wire can provide fixed support for resistance wire, prevent resistance
For silk because vibration or other factors are contacted with Can, support effect is good；Magnesium pipe main body hollow cavity and three, equilateral triangle are tiltedly
The middle section outwardly convex 4 of wall portion between side, the outer surface of convex portion be with concentric arc-shaped of hollow cavity, to adapt to triangle
Circular hollow inner cavity in the middle part of tee section increases wall portion thickness between three bevel edges in circular hollow inner cavity and equilateral triangle, it is ensured that
