In order to achieve the above purpose, the utility model adopts the following technical scheme: an open profile comprising a top face, side faces and a bottom face; be provided with the opening on the bottom surface, the top surface is equipped with the arc recess of two inside recesses at least along section bar length direction, and two arc recesses are connected through first linkage segment, and first linkage segment width is less than open-ended width.
Further, the side sets up with the top surface is perpendicular, and the bottom surface is provided with the kink of inside concave yield.
Further, the top surface comprises a second connecting section which can be connected with the side surface, and the width of the second connecting section is smaller than that of the first connecting section.
Further, the side surface is obliquely arranged relative to the top surface.
Further, the side includes third linkage segment and fourth linkage segment, and the third linkage segment is perpendicular with the top surface, and the fourth linkage segment sets up to the top surface slope.
Further, the fourth connecting section is shorter in length than the third connecting section.
Further, the distance between the radian top ends of the two arc-shaped grooves is smaller than the width of the opening.
Furthermore, the second connecting section is connected with the side surface through a first chamfer, and the side surface is connected with the bottom surface through a second chamfer.
Further, the section bar is integrally formed.
To sum up, the utility model discloses a section bar integrated into one piece adopts closed trapezium structure, both can realize the lightweight of section bar, does effectively improve the rigidity and the intensity of section bar self-generation, is provided with the strengthening rib structure on the section bar, can strengthen the intensity of section bar, through the combined action of structure and the material of section bar itself, has reached that section bar intensity is big, light in weight's purpose.

Detailed Description
In order to make the technical field personnel understand the utility model discloses the scheme, will combine the drawing in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.
Example 1
As shown in fig. 1-2, an open-type profile is characterized in that: comprises a top surface 1, a side surface 2 and a bottom surface 3; the bottom surface 3 is provided with an opening 4, the top surface 1 is at least provided with two arc grooves 11 which are recessed inwards along the length direction of the section bar, the two arc grooves 11 are connected through a first connecting section 12, and the width of the first connecting section 12 is smaller than that of the opening 4; the side surfaces 2 are arranged perpendicular to the top surface 1, and the bottom surface 3 is provided with a bending part 31 which is concave inwards. The utility model discloses a section bar integrated into one piece adopts open type structure, and the steel band is through the roll-in one shot forming of multichannel, and side 2 sets up perpendicular setting with top surface 1 perpendicularly and can let the section bar bear bigger power, and in addition, the bottom of section bar is provided with symmetrical 2 bottom surfaces 3, and two bottom surfaces 3 are the symmetrical setting, and the symmetrical setting can let the section bar atress more even, also can make the intensity of section bar more big, in addition the utility model discloses an open type design; therefore, the design can realize the light weight of the section bar and also can effectively improve the self-generated rigidity and strength of the section bar.
The top surface 1 comprises a second connecting section 13 which can be connected with the side surface 2, and the width of the second connecting section 13 is smaller than that of the first connecting section 12; the distance between the arc top ends of the two arc grooves 11 is smaller than the width of the opening 4. The utility model discloses a top surface is provided with arc recess 11, can regard as arc recess 11 to be the strengthening rib structure, and this structure can improve 12% compressive strength and torsional strength of section bar. In addition, the section bar of the utility model adopts ultra-high strength material, the material hardness HRC is more than or equal to 45 degrees, and the tensile strength reaches 1500-2400 Mpa. The purposes of high strength and light weight of the sectional material are achieved through the combined action of the structure and the material of the sectional material.
The second connecting portion 13 is connected to the side face 2 by a first chamfer 51, and the side face 2 is connected to the base face 3 by a second chamfer 52. The first chamfer 51 and the second chamfer 52 enable the profile to be smoother, less prone to scratching during transport, and the design of the radian is firmer than that of the right-angle shape.
Example 2
As shown in fig. 3-4, the embodiment 2 is different from the embodiment 1 only in the arrangement of the side surface 2 and the bottom surface 3, and the other arrangements are the same as the embodiment 1, so that the description is not repeated, in the embodiment, the side surface 2 is arranged obliquely relative to the top surface 1; the side surface 2 comprises a third connecting section 21 and a fourth connecting section 22, the third connecting section 21 is vertical to the top surface 1, and the fourth connecting section 22 is obliquely arranged relative to the top surface 1; the fourth connecting section 22 is shorter in length than the third connecting section 21. The bottom surface 3 in this embodiment has only one plane, and is different from embodiment 1, and this embodiment can be applied to an application scene different from embodiment 1, and can also be used with other section bars in a matching manner.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
