In said apparatus, described nut body is internal thread, and its material is ML08AL cold-forging steel.
In said apparatus, the diameter of described texturing zone is 14.5mm under normal conditions, and after swollen type, its diameter is 20mm to the maximum; After distortion, its diameter is more than or equal to 35mm.
In said apparatus, the Ω type that is shaped as of described cutting groove, its width L is 2.5mm.
In said apparatus, described base is waist type; The two ends of base are provided with flange; The bi-side of described base are provided with trimming.
In said apparatus, described watertightness barrier is waist type; The center of described watertightness barrier is provided with circular hole; The diameter of described circular hole is greater than the diameter under texturing zone normality, makes watertightness barrier arrive base through texturing zone; The outside spraying PVC dope of described watertightness barrier; Described two sided plaster is 3M glue.
In said apparatus, described watertightness barrier is EDPM foaming layer, and its thickness is 2.5mm.
The beneficial effects of the utility model are: texturing zone its diameter after swollen type can reach 20mm, more than the diameter after distortion can reach 35mm, meet the locking demand of the above macropore of 15mm position, can effectively realize locking function; The PVC of the EPDM foaming layer of waterproof gasket spraying simultaneously dope, and by the compression of EPDM foaming layer, compensated the rough property of PVC dope, EPDM foaming layer simultaneously adopts hole-closing structure design, has improved water proofing property.
