Of the present inventionly be processed with aperture in position corresponding to the vertical center line on 1/3 circular arc top.
Metal lower skeleton of the present invention is long strip sheet metal, and its entirety is 2/5 circular arc, is processed with outward aduncate circular hinges circle again in one end of 2/5 circular arc, and the half of hinge circle is narrow hinge strap; The other end of 2/5 circular arc extends along straight line, and it is curved that the extension board of extended spot is processed with downward Z-shaped, is processed with fixed groove on extension board.
The corresponding part of the circular arc vertical center line of 2/5 circular arc of the present invention is processed with aperture.
Hinge circle of the present invention is connected with square groove, forms skeleton circle after connecting, and metal felt liner point is welded in the inner side of skeleton circle.
Metal felt liner of the present invention is that material is that the Stainless Steel Wire of 1Cr18Ni9Ti is entwined, then processes flat liner with pressing.
Metal upper skeleton of the present invention and metal lower skeleton are that GH625 high-temperature alloy steel is made.
When use, open lower skeleton, after it is contacted with pipeline or cable, closure packs tightly, then bolt is through fixing slotted eye, and clip is fixed on body, can complete the installation of clip.
The effect of the aperture on upper and lower metal frame is to detect upper and lower metal frame processing to close defective use, after upper and lower metal frame assembles, if the aperture on upper and lower metal frame is concentric, that proves that upper and lower metal frame processing is qualified, if decentraction, proof has at least a processing defective, need to again process.
Advantage of the present invention is apparent, is mainly manifested in:
1, skeleton of the present invention adopts GH625 high-temperature alloy steel to make, and resistance to high temperature is superpower, and oxidation resistance is high.All there is good tensile property and fatigue behaviour from low temperature to 980 DEG C.
2, metal felt liner of the present invention adopts 1Cr18Ni9Ti stainless steel to make, and can be applied to acid-and base-resisting, and oil resistant, in resistant to elevated temperatures environment, can in 500 DEG C of hot environments, work for a long time, and material thermal expansion coefficient is low, and wear-resisting property is good, and shock resistance is strong.Long service life, reduces maintenance and repair expense.
3, clip of the present invention is designed to hinge type connection, and easy for installation, after inner liner metal felt, with pipeline, the laminating degree of circuit is good, can also ensure that clip can bear powerful vibration and the high temperature of aircraft, has improved Security and the fastening fixing reliability of clip.
4, the present invention is not only suitable for the fastening fixing of conventional pipeline, circuit, and meets pipeline, circuit fastening fixing of motor in Aeronautics and Astronautics industry.Clip is easy for installation, and after coated metal felt gasket, with pipeline, the laminating degree of circuit is good, can also ensure that clip can bear powerful vibration and the high temperature of aircraft, has improved Security and the fastening fixing reliability of clip.
The present invention has novel structure, it is easy, easy to use to process, be applicable to the advantages such as various pipelines, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
