A kind of section bar
The utility model relates to a kind of section bar, belongs to the material field.
In existing shelf was produced, the docking calculation between flat sheet and the flat sheet end face had a lot, such as, overlap joint, end face is bonding, and riveted joints etc. all are to make being connected firmly between the two boards at present, and are indeformable; But above method is difficult to accomplish both to be connected firmly, and is indeformable, and attractive in appearance, and sealing is not revealed.
Summary of the invention
The technical problems to be solved in the utility model is that existing Placement can not make the butt joint between flat sheet and the flat sheet end face, both has to be connected firmly, and is indeformable, and attractive in appearance, the effect that sealing is not revealed.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of section bar, symmetry was square centered by its transverse section was basic, respectively establish a mounting hole for four jiaos of the transverse section, the central through bore of a square-outside and round-inside is established in the center of transverse section, the central through bore inwall is provided with internal thread, is symmetrical arranged four T type grooves along the outer side of central through bore.
For guaranteeing to connect the attractive in appearance of appearance, four angles of described transverse section are arc angle.
The utility model has the advantages that: can make the butt joint between flat sheet and the flat sheet end face, both have and be connected firmly, indeformable, and also attractive in appearance, the effect that sealing is not revealed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 uses for the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, symmetry was square centered by the transverse section of the utility model product was basic, four angles of transverse section are arc angle, the central through bore 1 of a square-outside and round-inside is established in the center of transverse section, central through bore 1 inwall is provided with internal thread, is symmetrical arranged four T type grooves 2 along the outer side of central through bore 1.
As shown in Figure 2, during use, sheet material to be connected snaps in the corresponding T type groove 2 as required, section bar itself then is fixed on the attachment face by mounting groove 2, when needing vertically to connect between section bar and the section bar, can select for use angled piece 4 that two section bars are linked together, the outside that is each bar right angle fillet of angled piece 4 respectively is connected and fixed a section bar, in the time of fixedly, the head of screw rod is positioned at T type groove 2, T type groove 2 stretches out in bar portion and the through hole and the nut that pass on the right angle fillet of angled piece 4 are used, and described angled piece 4 is existing product, and the bolt and nut of described connection usefulness can be selected existing T type bolt and nut for use; Central through bore 1 general and screw fit use, and mounting groove 2 generally is used with bolt and nut.
