Example 1

Referring to fig. 1 to 5, embodiment 1 is a steel door leaf buckle structure, which includes a door leaf body 3, where the door leaf body 3 is composed of a panel 2 and a back plate 1; a first folded edge 11 and a second folded edge 12 are respectively arranged at two ends of the back plate 1, the first folded edge 11 is an insertion end, and a bulge 121 is arranged on the second folded edge 12; one end of the panel 2 is provided with a socket 21, the other end of the panel is provided with an open bayonet 22, and the open bayonet 22 is provided with a barb, so that after the back plate 1 is clamped into the socket 21 through the first folded edge 11, the other end of the protrusion 121 is counted into the open bayonet 22 of the panel 2, the protrusion 121 is fixed according to the barb, further, the assembly of the door leaf is completed in detail by respectively clamping the first folded edge 11 and the second folded edge 12 of the back plate 1 into the socket 21 and the open bayonet 22 of the panel 2 to complete fastening and fixing, and therefore, when the back plate 1 and the panel 2 are connected first, firstly, the back plate 1 is operated to insert the first folded edge 11 into the socket 21 of the panel, and then the protrusion 121 of the second folded edge 12 at the other end of the back plate 1 is clamped into the open bayonet 22, compared with the prior art, the door leaf assembly can form a welding point after welding and needs to be polished manually, the aesthetic feeling of door leaf itself also can be influenced through the back welding point of polishing, and whole process flow is consuming time longer simultaneously, and is very inconvenient, and links to each other through the mode of lock joint between backplate 1 and the panel 2, and artifical concatenation is convenient, and the fixed effectual of the higher and its door leaf of efficiency effectively reduces manual operation intensity and the degree of difficulty.

The extruding end of the bulge 121 is a circular arc surface structure, the back side is a plane structure, so that the bulge 121 is clamped into the barb to contact the back side for fixation, the inserting port 21 is a V-shaped structure, and the connection part of the interface 21 and the panel 2 is provided with a sloping plate 23 for connection, in particular, the panel 2 can be fixed when the back plate 1 is connected with the panel 2, the back plate 1 vertically moves downwards from the upper part of the panel 2, so that the straight plate structure of the first folded edge 11 is clamped into the bottom of the insertion opening 21 to be pressed against and fixed, and the protrusion 121 of the second folded edge is clamped into the open bayonet 22, thereby realizing the fastening between the back plate 1 and the panel 2, the inclined plate 23 can prevent the straight plate of the clamped first folded edge 11 from being forced to be separated from the inserting port 21 of the V-shaped structure, the barb structure of the open bayonet 22 props against the back side of the protrusion 121, so that the back plate 1 is prevented from being loose and falling off relative to the panel 2 at the left side and the right side; in addition, it should be noted that, when the panel 2 and the back plate 1 are fixed, the panel 2 may also be fixed, and the first folded edge 11 and the second folded edge 12 of the back plate 1 move tightly against the surface of the panel 2 until the first folded edge 11 is clamped into the insertion opening 21, and the protrusion 121 of the second folded edge 12 presses the barb to be clamped into the open bayonet 22 to complete the fixing.

First hem 11 and second hem 12 buckle towards the same, first hem 11 is buckled along the 1 outside of backplate, second hem 12 is buckled along its inboard, bayonet socket 21 and open bayonet socket 22 locate the homonymy of panel 2, it is concrete, through setting up this structure, make only need remove single panel 2 or backplate 1 and operate and carry out the lock joint with it and another subassembly at the concatenation in-process, and then made things convenient for workman's work to observe both sides junction and docked, be favorable to the actual operation of production equipment.

First hem 11 and second hem 12 all become 90 with the continuous board of backplate 1 and buckle, and this angle is conveniently bent and the preparation, guarantees the firm in connection nature between backplate 1 and panel 2.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
