Abstract
The invention provides a screw. The screw comprises a nut and a screw rod, wherein threads are arranged on the edge of the nut, a projection is arranged at the end, close to the nut, of the screw rod, the diameter of the nut is 500-600 mm, the length of the screw rod is 2000 mm-2500 mm, and the screw body is made from steel No.45. The screw has the beneficial effects that the design and structure are simple, the nut can be directly embedded in a connected object, the appearance attractiveness of the connected object is improved, the connection is firm, and the screw is durable.
Description
Technical field
The invention belongs to fixed component field, especially relate to a kind of screw.
Background technique
Screw utilizes the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, the by easy stages instrument of fastening implements parts.Screw is industrial necessity indispensable in daily life.In prior art, the nut outer surface in screw structural is provided with 1-shaped open or cross mouth, and when using screw articles, nut is positioned at outside object surface, and nut can form projection at object surface, have impact on object attractive in appearance.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of reasonable in design, and structure is simple, robust screw.
For solving the problems of the technologies described above, the technical solution used in the present invention is: screw, comprises nut and screw rod, it is characterized in that: described nut edge arranges teeth, screw rod arranges projection near one end of nut, and the diameter of described nut is 500mm-600mm, and the length of screw rod is 2000mm-2500mm.
Described screw body is made up of No. 45 steel.
Described screw rod is smooth structure.
The advantage that the present invention has and good effect are: reasonable in design, and structure is simple, and nut can directly embed in the object that is connected, improves the aesthetics being connected thing, sturdy and durable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure:
1, nut; 2, screw rod; 3, teeth; 4, protruding.
Embodiment
As shown in Figure 1, a kind of screw of the present invention, is made up of No. 45 steel, the master gage of No. 45 steel is decided to be: tensile strength is 600MPa, and yield strength is 355MPa, and elongation percentage is 16%, reduction of cross sectional area is 40%, and ballistic work is 39J, uses No. 45 steel to make screw sturdy and durable.A kind of screw, comprise nut 1 and screw rod 2, screw rod 2 is smooth structure, and nut 1 edge arranges teeth 3, and screw rod 2 arranges protruding 4 near one end of nut 1, the diameter of nut 1 is 500mm-600mm, and the length of screw rod 2 is 2000mm-2500mm.
The present invention is reasonable in design, and structure is simple, and nut can directly embed in the object that is connected, improves the aesthetics being connected thing, sturdy and durable.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
