The utility model discloses a kind of stainless steel rectangular tubes, including rectangular outer tube body and circular interior tube body, the outer diameter of interior tube body is equal to the inside length of side of outer tube body, four corners of outer tubular body are provided with support plate, support plate is arranged along the radial direction of interior tube body, the side of support plate and the outer wall of interior tube body connect, and the other side of support plate pushes against the inner corner of outer tube body.The stainless steel rectangular tube is used as support by the way that circular interior tube body is arranged in rectangular outer tube body, and the outer wall of interior tube body pushes against the middle part of four side walls of outer tube body, and recess is not easily formed when four side walls of outer tube body are by external impact force；In addition, interior tube body and outer tube body form composite construction so that outer tube body has stronger tolerance level to external force, improves the buckle resistance energy of outer tube body, it is made to be not susceptible to be bent.The rectangular tube is due to that with high anti-extrusion, buckle resistance energy, can be applied in machinery, building or the engineering of high intensity.
Description
Technical field
The utility model is related to a kind of stainless steel pipes, more specifically, it relates to a kind of stainless steel rectangular tube.
Background technology
With the development of society, industry is constantly progressive, steel pipe is increasingly used in building, industry, manufacturing industry etc.
Field.
Steel pipe is roughly divided into pipe and square tube, and square tube is a kind of square pipe, is exactly the equal steel pipe of the length of side, it be by
Strip is rolled by process.
Square tube is usually applied to engineering structure, building, decoration etc. frequently as load cast.Due to square tube wall thickness compared with
It is thin, and the crush resistance energy of square tube, buckle resistance can be equal not as good as pipe, so, square tube is easy out when by larger external force
The case where now recess is even bent makes the range that it is applied be subject to certain restrictions.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of stainless steel rectangular tube, tool
There is higher crush resistance can be with buckle resistance energy.
To achieve the above object, the utility model provides following technical solution：
A kind of stainless steel rectangular tube, including the outer tube body that cross sectional shape is side's annular and the inner tube being interspersed in inside outer tube body
The cross sectional shape of body, interior tube body is circular ring shape, and the outer diameter of interior tube body is equal to the inside length of side of outer tube body, and interior tube body is solid with outer tube body
Fixed, the outer wall of interior tube body pushes against in outer tube body with the middle part of four side walls of outer tube body, in four corners of outer tubular body
Place is provided with support plate, and support plate is arranged along the radial direction of interior tube body, and the side of support plate and the outer wall of interior tube body connect, support plate
The other side push against outer tube body inner corner.
Preferably：The corner of the inside of the outer tube body is additionally provided with L-shaped contact plate, contact plate and corner
Portion is bonded, and between contact plate and interior tube body, the other side and the contact plate of support plate are connected and fixed support plate.
Preferably：It is provided with filler in gap between the outer tube body and interior tube body.
Preferably：Supporting rack is additionally provided in said inner tube body, the cross-sectional shape of support frame as described above is cross
Shape.
Preferably：Four support edges of support frame as described above are located at the middle part of the side wall of outer tube body.
Preferably：Support frame as described above ecto-entad gradually thickens.
Compared with prior art, the utility model has the advantages that：The stainless steel rectangular tube, by rectangular outer tube body
Circular interior tube body is set as support, the outer wall of interior tube body pushes against the middle part of four side walls of outer tube body, when outer tube body
It is not easily formed recess when four side walls are by external impact force；In addition, interior tube body and outer tube body form composite construction so that
Outer tube body has stronger tolerance level to external force, improves the buckle resistance energy of outer tube body, it is made to be not susceptible to be bent.This is rectangular
Pipe is due to that with high anti-extrusion, buckle resistance energy, can be applied in machinery, building or the engineering of high intensity.
Description of the drawings
Fig. 1 is the cross-sectional view of rectangular tube.
Reference sign:1, outer tube body；2, interior tube body；3, support plate；4, contact plate；5, supporting rack；6, filler.
Specific implementation mode
Referring to Fig.1, a kind of stainless steel rectangular tube, including cross sectional shape are the annular outer tube body 1 in side and are interspersed in outer tube body 1
The cross sectional shape of internal interior tube body 2, interior tube body 2 is circular ring shape, and the outer diameter of interior tube body 2 is equal to the inside length of side of outer tube body 1, interior
Tube body 2 is fixed with outer tube body 1, since the outer wall of interior tube body 2 is just at the interior middle part with four side walls of outer tube body 1 of outer tube body 1
It pushes against, and 2 crush resistance of circular interior tube body can very well, so when four side walls of outer tube body 1 are by external impact force
It is not easily formed recess；In addition, interior tube body 2 and outer tube body 1 form composite construction so that outer tube body 1 has external force stronger
Tolerance level improves the buckle resistance energy of outer tube body 1, it is made to be not susceptible to be bent.
Herein on basis, it also is provided with support plate 3 between four corners inside outer tube body 1, support plate 3 is along inner tube
The radial setting of body 2, the side of support plate 3 are connect with the outer wall of interior tube body 2, and the other side of support plate 3 pushes against the interior of outer tube body 1
Portion's corner.The setting of support plate 3 makes the rotation angle position of outer tube body 1 also can be enhanced the whole of outer tube body 1 by additional support
The load intensity of body.
As shown in Figure 1, being additionally provided with L-shaped contact plate 4, contact plate 4 and corner portion in the corner of the inside of outer tube body 1
Fitting, between contact plate 4 and interior tube body 2, the aforementioned other side and the contact plate 4 of support plate 3 are connected and fixed support plate 3.It connects
The setting of touch panel 4 increases the region area being supported on outer tube body 1, further increases the load to external force of outer tube body 1
Performance makes outer tube body 1 less be also easy to produce recess or deformation.
To further increase the region area being supported on outer tube body 1, the sky between outer tube body 1 and interior tube body 2
Filler 6 is provided in gap.
