Welt and cutting composition, cutting are equipped with lock tooth, and the first welt, the second welt two inner walls adjacent in air hose main body paste
It closes, cutting is set in the gap of the air hose main body between the first welt, the second welt.
Further improvement of the utility model is: the first welt, the second welt width are 15mm.
Further improvement of the utility model is: the angle between cutting and the first welt, the second welt is 45 °.
Further improvement of the utility model is: the length of cutting is 10mm, and the front end of cutting is taper head, cutting
Conical head angle of taper be 30 degree.
Further improvement of the utility model is: cutting is made of PVC, and the lock tooth in cutting is arranged in serration type, often
The flank of tooth of a lock tooth is with a thickness of 0.03-0.06mm.
Further improvement of the utility model is: the first protective layer with a thickness of 0.02-0.05mm, the first protective layer
It is made of color steel, gap width 1-2mm.
The gap that 1-2mm is reserved on the first protective layer, is fixed on air hose for the first welt of interpolation slit device, the second welt
On the inner wall of main body, cutting is inserted into the seam gap reserved on the first protective layer by the conical head of front end, lock tooth by squeezing and
Interior relay is formed between phenolic foam board layer, the first protective layer, the lock tooth in cutting is stuck on the inside of gap, so that cutting must not take off
It falls.
The utility model has the advantages that
The utility model, which avoids caused by ventilation shaft comes unglued, to leak out, and causes inner surface caused by phenol formaldehyde foam weathering
The first sag of protecting coating, greatly strengthen the connectivity and bite force of the first protective layer Yu phenolic foam board layer.First welt,
The setting of second welt enhances stress, while also preventing interpolation slit device and falling off；First welt of 15mm length, the second patch
Side and the connectivity of the first protective layer are best, and globality is most strong.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
1- air hose main body；2- interpolation slit device；The first welt of 3-；The second welt of 4-；5- cutting；6- locks tooth；The gap 7-；101-
