Abstract
The utility model relates to a quadrilateral plum blossom tube for a medical appliance; the cross section of a tube body (1) of the quadrilateral plum blossom tube takes on a special-shaped structure; the special-shaped structure comprises circular arc convex parts (1-1) and circular arc concave parts (1-2); the four corners of the tube body (1) are the circular arc convex parts (1-1), and the circular arc concave parts (1-2) are respectively arranged between every two adjacent circular arc convex parts (1-1); the surface of the tube body (1) is coated with a zinc coating layer (2); and the material of the quadrilateral plum blossom tube is 20#. The quadrilateral plum blossom tube for the medical appliance has the structure to lead the quadrilateral plum blossom tube to be evenly stressed and have stronger bending resistance, torsional strength and corrosion resistance.
Description
(1) technical field
The utility model relates to a kind of special-shaped seamless steel pipe, especially relates to a kind of medical apparatus and manages with four jiaos of plum blossoms, belongs to the metallic material technical field.
(2) background technique
At present, seamless steel pipe is widely used in manufacturing structure spare and mechanical parts, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle frame and the construction etc.Make ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, economical with materials and machining period as rolling bearing lasso, jack cover etc., are extensively made with seamless steel pipe at present.Seamless steel pipe still is various conventional weapon indispensable material, and gun barrel, gun barrel etc. is all wanted steel pipe manufacturing.In these seamless steel pipes, most seamless steel pipes are pipes.
Yet pipe also has certain narrow limitation:
The shape restriction of pipe makes it can't be used for some particular surroundingss;
Because the moment of inertia of pipe and section modulus are less, its bending resistance and anti-twisting property are relatively poor;
The weight of pipe itself is bigger, and is bigger to the pressure of its supporting part;
It is more to make the steel that pipe consumes, and makes that its cost is higher.
Above a variety of causes has limited the Applicable scope of pipe, does not therefore adopt pipe to be used as structural member or machine part under some particular surroundingss.For example many medical apparatuss need be considered bending resistance, the anti-twisting property of weldless tube, and certain anti-corrosion capability will be arranged, and so just can not use the less pipe of moment of inertia and section modulus to make.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of medical apparatus to manage with four jiaos of plum blossoms, and this medical apparatus makes it stressed evenly with the structure of four jiaos of plum blossom pipes, bending resistance, antitorque and anti-corrosion capability is stronger.
The purpose of this utility model is achieved in that
A kind of medical apparatus is managed with four jiaos of plum blossoms, the section of the body of these four jiaos of plum blossom pipes is abnormally-structured, this abnormally-structured circular arc projection and circular arc recess part of including, four angles of described body are the circular arc projection, be described circular arc recess part between adjacent two circular arc projections, described body surface is covered with zinc coat, and the material of described four jiaos of plum blossom pipes is 20#.
The beneficial effect that the utlity model has is:
This medical apparatus is an arc structure with three angles of four jiaos of plum blossom pipes, is described circular arc recess part between adjacent two circular arc projections, and such structure makes four jiaos of plum blossoms pipe stressed evenly, its bending resistance, antitorque and anti-corrosion capability is also stronger.
(4) description of drawings
Fig. 1 is the cross-sectional configuration schematic representation of the utility model medical apparatus with four jiaos of plum blossom pipes.
Wherein: body 1, circular arc projection 1-1, circular arc recess part 1-2, zinc coat 2.
(5) embodiment
As Fig. 1, the utility model relates to a kind of medical apparatus and manages with four jiaos of plum blossoms, the section of the body 1 of these four jiaos of plum blossom pipes is abnormally-structured, this abnormally-structured circular arc projection 1-1 and circular arc recess part 1-2 of including, four angles of described body 1 are circular arc projection 1-1, be described circular arc recess part 1-2 between adjacent two circular arc projection 1-1, described body 1 surface is covered with zinc coat 2, and the material of described four jiaos of plum blossom pipes is 20#.
Claims (1)
1. a medical apparatus is managed with four jiaos of plum blossoms, it is characterized in that: the section of the body of these four jiaos of plum blossom pipes (1) is abnormally-structured, this abnormally-structured circular arc projection (1-1) and circular arc recess part (1-2) of including, four angles of described body (1) are circular arc projection (1-1), it between adjacent two circular arc projections (1-1) described circular arc recess part (1-2), described body (1) surface is covered with zinc coat (2), and the material of described four jiaos of plum blossom pipes is 20#.
