Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the cabinet piece is pieced together outward to punching press formula rack of this embodiment, and outer cabinet piece 10 of piecing together is the square box body structure of one side open-ended, and its concrete structure is: the box body comprises a base body 101, wherein folding edges 102 are formed on the periphery of the base body 101 at 90 degrees respectively, adjacent folding edges 102 are vertically overlapped, a tubular part protruding towards the inner side of the box body is arranged on each folding edge 102, and a threaded hole 106 is formed in each tubular part.

The threaded holes 106 on the two folded edges 102 which are arranged in parallel are coaxially arranged.

The outer cabinet 10 is a cube structure with an opening on one side.

As shown in fig. 2, the assembly process of the present invention is as follows:

firstly, optionally abutting one of four folded edges of the outer cabinet assembly 10 with a first cabinet assembly side 201 of a first cabinet frame 20, abutting the other two folded edges perpendicular to the selected folded edge with a first wrapped corner edge 203, and then enabling a screw 40 to penetrate through a first through hole 202 on the first cabinet frame 20 and lock into a threaded hole 106 of the selected folded edge to complete positioning and locking of the outer cabinet assembly 10 and the selected first cabinet frame 20; fig. 2 shows only one external cabinet assembly 10, and the complete cabinet assembly of two cabinets has at least 6 splicing nodes as shown in fig. 2.

For the adjacent second cabinet frame 30, the second corner-wrapped edge 303 and the first corner-wrapped edge 203 are aligned and coplanar through moving and matching, the second cabinet splicing side 301 is abutted against the opposite side edge of the selected edge, and then the screw 40 passes through the second through hole 302 of the second cabinet frame 30 and is locked into the edge-folded threaded hole 106 abutted against the second cabinet splicing side 301, so that the positioning, connection and fixation of the outer cabinet splicing piece 10, the first cabinet frame 20 and the second cabinet frame 30 are completed.

In the prior art, most of the connecting pieces connecting the individual cabinets in series adopt the outer hexagon nut columns 50 as shown in fig. 3, two connecting pieces are used as positioning end surfaces 501, and the inside of the connecting pieces is axially provided with the locking threaded through holes 502.

The contact surfaces of the hemmed surface of the outer cabinet assembly 10, the first cabinet frame 20 and the second cabinet frame 30 of the utility model are far larger than the contact surfaces of the positioning end surface 501 of the outer hexagon nut column 50, the first cabinet assembly side 201 and the second cabinet assembly side 301 in fig. 4; in addition, the two folded edges of the outer assembled cabinet 10 abutting against the first wrap angle edge 203 and the second wrap angle edge 303 in fig. 2 have a positioning function besides rotation stopping when the screw 40 is locked, the hexagonal rotation stopping surface 503 of the outer hexagonal nut column 50 in fig. 4 has only rotation stopping function and has no positioning function,

when any two of the four opposing flaps 102 are selected as the fastening locations, the remaining two opposing flaps become positioned to abut and fit the first wrap angle edge 203 and the second wrap angle edge 303 of the cabinet frame in fig. 2. Comparing the outer cabinet assembly 10 with the outer hexagonal nut stud 50 of the existing cabinet assembly in fig. 3, it can be seen that: four folded edges as positioning surfaces: the contact area of any one folding edge 102 and the frame is multiple times of the single-side positioning end surface 501 of the outer hexagonal nut column 50; the two opposite folded edges which are in butt fit and rotation prevention are also obviously better than the hexagonal rotation prevention surface 503 of the outer hexagonal nut column 50, and the coating area between the two opposite folded edges is also multiple times of that of the rotation prevention surface 503. Therefore, compared with the traditional connecting piece, the utility model has obvious technical advantages.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
