Summary of the invention

The object of the present invention is to provide a kind of incrust tube-in-tube structure that is easy to discern and identify, to prolong its service life.

For achieving the above object, solution of the present invention is:

A kind of tube-in-tube structure, it includes: a cylindrical shell, it has an outer fringe surface; One indicates the unit, is formed at the surface of aforementioned cylindrical shell, and this sign unit is to be formed with the corresponding chase that indicates in drum surface, apply a dyed layer in the chase, drum surface coating one coating, and coating is not attached to the dyed layer surface, and the color of this coating and dyed layer have tangible contrast.

These cylindrical shell two ends are formed with a cover oral area and a cover portion of pulling respectively, the bolt that the corresponding desire lock of the bore of cover oral area unloads, the shape and the size of nut, and cover is pulled the shape of the corresponding wrenching bar of bore of portion with big or small.

Size, metric and English specification or trade mark are distinguished in being labeled as of this sign unit.

The interior infiltration of dyed layer that indicates the unit has manganese phosphate, forms the surface that similar epithelium is handled.

After adopting such scheme, dyed layer of the present invention can infiltrate manganese phosphate, and directly be attached to the predetermined chase inner surface that indicates that forms, utilize chase rough surface face to promote its adhesive force, and see through the aberration that sleeve surface coating and dyed layer produce, make the sign unit of sleeve form a kind of plan like the epithelium processing, allow the literal, the trade mark that indicate the unit can know identification, and can prevent effectively that dyed layer from peeling off, effectively prolong its service life, and increase its surcharge, and can promote competitiveness of product and economic benefit.

Next cooperate graphic and figure number; lifting a preferred embodiment simultaneously is described further; but the following stated is only for being used for explaining preferred embodiment of the present invention; be not according to this present invention to be done any pro forma restriction; therefore every under invention spirit of the present invention; the modification of any pattern of being done or change all must belong to the category that the invention is intended to protect.
