Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an inner handle shaft with a long service life comprises a handle shaft body 1, a first through hole 2 and a second through hole 3 are respectively formed on the surface of the handle shaft body 1, the handle shaft body 1 comprises a base layer 4, a reinforcing layer 5 is fixedly connected to the surface of the base layer 4, a coating 6 is fixedly arranged on the surface of the reinforcing layer 5, the base layer 4 is made of high-carbon chromium steel, the reinforcing layer 5 is made of a titanium alloy layer, the coating 6 is made of wear-resistant ceramic paint, the first through hole 2 is square, the second through hole 3 is round, a label 7 is arranged on the right side of the surface of the handle shaft body 1, a fixing hole 8 is formed in the left side of the handle shaft body 1, the left side of the fixing hole 8 is round, the base layer 4 is arranged, the high-carbon chromium steel is used as a special material to enable the hardness of the handle shaft body 1 to be higher, by arranging the reinforcing layer 5, the titanium alloy has high strength, good corrosion resistance and high heat resistance, and the high-strength titanium alloy exceeds the strength of a plurality of alloy structural steels, so the specific strength of the titanium alloy is far greater than that of other metal structural materials, parts with high unit strength, good rigidity and light weight can be manufactured, by arranging the coating 6, the wear-resistant ceramic coating is a non-metal gelled material, is a powdery ceramic material prepared by adopting acid-resistant and alkali-resistant artificially synthesized raw materials through strict process proportion and advanced inorganic polymerization technology, can increase the wear resistance of the handle shaft body 1, and solves the problems of shorter service life caused by lower strength, poorer corrosion resistance and poorer wear resistance of the handle shaft in the existing inner handle shaft by matching the handle shaft body 1, the first through hole 2, the second through hole 3, the base layer 4, the reinforcing layer 5 and the coating 6, the inner handle shaft has the advantage of long service life and is worthy of popularization.
