Based on the folding unit cabinet of the present invention, the present invention also provides a folding combination cabinet, comprising at least two folding unit cabinets, each of which is connected to each other. Compared with the prior art, the folding combination cabinet of the present invention has the same advantages as the folding unit cabinet of the present invention, and will not be repeated here.
In one embodiment, each of the folding unit cabinets is arranged in a row. This design is convenient for each of the folding unit cabinets to be connected to each other, and the appearance is regular.
In the folding unit cabinet of the present invention, the structure of each of the folding unit cabinets does not need to be completely consistent, and can be adjusted accordingly according to actual needs. for example:
In one embodiment, the two support frames 1 of the two adjacent folding unit cabinets in the horizontal direction are connected to each other, and the two adjacent folding unit cabinets in the vertical direction share one support frame 1. This design facilitates the combination of folding unit cabinets according to actual needs, saves the material of the unit cabinets, and facilitates the combination of suitable folding combination cabinets according to the required size, thereby facilitating the use of folding combination cabinets.
In some cases, it can be specifically designed that the folding unit cabinet on the left is provided with two side plates 3, and the folding unit cabinet on the right side is provided with one side plate 3, which is located on the right side.

This design facilitates the combination of multiple folding unit cabinets, thereby facilitating the installation of the combined cabinets. In such a design, through the first sliding groove 13 and the first sliding bar 14, two adjacent folding unit cabinets are connected together, thereby facilitating the combination of the folding unit cabinets in the horizontal direction.
Of course, the side frames 12 of the two support frames 1 of the two adjacent folding unit cabinets in the horizontal direction may also be integrally formed.
In one embodiment, the position of the two support frames 1 of the two adjacent folding unit cabinets in the horizontal direction are limited by the following method: the support frame is provided with a positioning groove 15 at the end of the first sliding bar 14, the groove wall of the first sliding groove 13 is provided with a positioning block 16, and the positioning block 16 is clamped in the positioning groove 15 in the usage state. In such a design, through the cooperation of the positioning groove 15 and the positioning block 16, the positional relationship between two adjacent support frames 1 is avoided to change in the usage state, so as to ensure the stability of the folding combination cabinet.
In the specific implementation, it is sufficient to arrange a side plate 3 between two adjacent folding unit cabinets in the horizontal direction, so that the design can achieve the effect of saving production materials while ensuring the stability of the folding unit cabinets; The carrying plate 7 on the top of the uppermost folding unit cabinet and the carrying plate 7 on the bottom of the lowermost folding unit cabinet can be integrally formed on the corresponding support frame 1, and the other carrying plates 7 are configured to be detachably installed, which is convenient for forming spaces with different heights and dimensions as required. Designed in this way, the height dimension of the folding combination cabinet can be adjusted by arranging the detachably installed carrying plate 7, which facilitates the storage of articles and facilitates the use of the folding combination cabinet.
In one embodiment, a rib 31 extends outward from the rear side of the corresponding side plate 3, and the rib 31 is used for blocking on the inner side of the rear plate 2 of the adjacent folding unit cabinet to prevent the rear plate 2 of the adjacent folding unit cabinet from being folded inward. In this design, the position of the rear plates 2 of the adjacent folding unit cabinets are limited by the outwardly extending ribs on the side plates 3. This prevents the rear panels 2 of the adjacent folding unit cabinets from being folded inward during use, thus ensuring the stability of the folding combination cabinet.
In one embodiment, a limiting hole 32 is provided at the bottom of the side plate 3, and a positioning column 33 is provided on the support frame corresponding to the position of the limiting hole, and the lower surface of the positioning column 33 is configured to be an arc-shaped convex structure. Designed in this way, the positioning column 33 positions the limiting hole 32 on the side plate 3, and the arc-shaped convex structure prevents the side plate 3 from being folded inward by itself without external force.
After the foldable cabinet unit of the present invention is folded, a stable gap space is formed relative to the top plate and the bottom plate after the rear side plate and the support column are folded, and the gap space can just place an uninstalled door body. Therefore, the folded folding cabinet unit not only reduces the volume, but also achieves the function of storing the only “part” of the folding cabinet unit, and the structural parts of the folded unit cabinet are against each other, which increases the folded strength of the folded unit cabinet and avoids pressure damage during transportation.
It will be apparent to those skilled in the art that the invention is not limited to the details of the above-described exemplary embodiments, but that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Accordingly, the embodiments should be regarded in all points of view as exemplary and not restrictive, the scope of the invention being defined by the appended claims rather than the foregoing description, and it is therefore intended that the scope of the invention be defined by the appended claims rather than by the foregoing description. All changes within the meaning and range of equivalents of the elements are embraced in the present invention.
