Technical field
This utility model relates to tubing technical field, is specifically related to a kind of special stainless steel tubing.
Background technology
Now the rustless steel cold-drawn tubing of main flow is the circular pipe of cylindrical inner circle the most on the market, only external diameter, internal diameter and
There are differences on wall thickness.The convenient lock used under the special environment such as train, aircraft at present is all the lock core using inner core abnormity,
Just can open easily with the use of the key identical with abnormity inner core.
Such inner core abnormity lock core, be typically all processing one annulus, at annulus internal ring enterprising line cutting or
Other cutting techniques of person, make flower pattern, such process not only cumbersome, and inefficiency.It addition, abnormity inner core is identical
Key life-time service after wear and tear more serious, be not easy to maintenance, integral replacing cost is high.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, it is provided that a kind of special stainless steel pipe
Material, its interface not easy fracture, ensure overall service life.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is to be achieved through the following technical solutions:
A kind of special stainless steel tubing, including chapped pipe body, the outer shroud cross section of described chapped pipe body is rounded,
The internal ring cross section of described chapped pipe body is regular hexagon, is equipped with removable resistance in the internal ring of described chapped pipe body
Mill internal lining pipe, the outer shroud of described abrasion-proof inner lining tube matches with the internal ring of chapped pipe body, the internal ring of described abrasion-proof inner lining tube
Cross section is also in regular hexagon, and beeline d of the top of the horn distance chapped pipe body outer shroud of described abrasion-proof inner lining tube is 25-
30mm。
Further, described chapped pipe body is cold drawing stainless steel pipe.
Further, described abrasion-proof inner lining tube is plastic tube.
Further, the outer annular diameter of described chapped pipe body is 90-100mm.
Further, the thickness of described abrasion-proof inner lining tube is 5-10cm.
The beneficial effects of the utility model are:
1, the special stainless steel tubing that this utility model provides is for the lock core of positive hexa-prism structure, is provided with cross section in just
Hexagonal internal ring, it is to avoid the operation of secondary operations shape after tube forming, process time is short, and efficiency is high, and processes
On the tubing internal ring gone out, corner angle are clearly demarcated, can direct plunge into use after polishing section.
2, being equipped with abrasion-proof inner lining tube in internal ring, the outer shroud of abrasion-proof inner lining tube matches with the internal ring of chapped pipe body,
It is difficult to during use rotate, it is ensured that the normal realization of function of key；On the other hand, abrasion-proof inner lining tube is plastic tube, after serious wear
Being conveniently replaceable, replacement cost is relatively low.
Certainly, implement arbitrary product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of this utility model embodiment, embodiment will be described below required for make
Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only embodiments more of the present utility model,
