Further, the top shape adaptation of first bayonet socket and stand, the stand is towards the lateral wall of first inside wall and the tip parallel and level of first end. Further improving the stability of the structure and leading the whole appearance to be more beautiful.
Further, the second bayonet socket and first end shape adaptation, tip, the lateral wall of first end all with the laminating of second inside wall. The cross beam, the oblique beam and the upright post are nested and butted more compactly, the stability of the structure is further improved, and the overall appearance is more attractive.
Furthermore, the crossbeam, sloping all can dismantle with the stand and be connected. The stability of structure is improved, and the installation and the dismantlement are convenient.
Furthermore, the cross beam and the oblique beam are connected with the upright post through corner connectors and self-tapping screws in a matched mode. Further improve the stability of structure, easy operation, be convenient for installation and dismantlement.
Furthermore, the cross beam, the oblique beam and the upright post are all made of aluminum materials. The aluminum alloy material is light in weight, convenient to install and transport, free of corrosion and long in service life.
Furthermore, the cross beam, the oblique beam and the upright post are all aluminum tubes. The structure is convenient to transform and connect.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a stand cover embedding crossbeam in the first bayonet socket, the hookup location of stand and crossbeam overlaps the second bayonet socket of embedding sloping again, forms the stoplog structure that the two-stage cover inlayed, realizes that the cover of crossbeam, sloping and stand inlays fixedly, increases the stability of structure, easy operation, the installation and dismantlement of being convenient for improve work efficiency, and need not the welding, whole appearance is more pleasing to the eye, need not to be equipped with special welding technique type talent, reduces the cost of labor.

Detailed Description
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings:
as shown in fig. 1 and 2, a stair corner connecting structure includes a vertical column 10, a cross beam 20, and an oblique beam 30, ends of which abut against each other, the end of the cross beam 20 abutting against the vertical column 10 and the oblique beam 30 is a first end 210, an end of the first end 210 is concavely provided with a first bayonet 220 with a downward opening, a top end of the vertical column 10 is inserted into the first bayonet 220, an end of the oblique beam 30 abutting against the cross beam 20 and the vertical column 10 is a second end 310, an end of the second end 310 is provided with a second bayonet 320 with a downward opening, the first end 210 is inserted into the second bayonet 320, and a top end of the vertical column 10 is also clamped into the second bayonet 320.
In the first bayonet 220 of stand 10 cover embedding crossbeam 20, the hookup location of stand 10 and crossbeam 20 overlaps the second bayonet 320 of embedding sloping 30 again, form the stoplog structure that the two-stage cover inlayed, it is fixed to realize the cover of crossbeam 20, sloping 30 and stand 10 and inlay, increase the stability of structure, and easy operation is convenient for install and dismantle, improves work efficiency, and need not the welding, whole appearance is more pleasing to the eye, need not to be equipped with special welding technique type talent, reduce the cost of labor.
In the present embodiment, the cross beams 20, the inclined beams 30 and the vertical columns 10 are all made of aluminum materials and are in the form of aluminum channels, and are used as main bearing parts of the stairs. The aluminum alloy material is light in weight, convenient to install and transport, corrosion-resistant and long in service life, and the aluminum alloy tube is convenient to transform and connect in structure due to the adoption of the aluminum tube, and the structural strength is improved. The cross beams 20, the oblique beams 30 and the upright columns 10 can also adopt other forms of materials according to actual needs.
