The eight plug bodies 30 are respectively disposed at the bolting slots 13 of the upper and lower two-layer boards 10, that is, each plug body 30 is correspondingly provided with a bolting slot 13; the plug body 30 is slightly cylindrical, and is provided with a a longitudinally engaging slot 31 and a bottom end 312 of the bottom end, wherein the bottom portion 312 is provided with a lifting platform 313 at a position above the inner side, and the lifting platform 313 is provided with a latching recess 33 at the bottom of the plug 30, and A positioning slot 311 is formed on the inner side of the engaging slot 31 relative to the upper portion of the lifting platform 313. In other words, the engaging slot 31 includes the positioning slot 311, that is, the positioning slot 311 is located inside the engaging slot 31. Location The plug body 30 is provided with a lock groove 32 on one side of the joint groove 31, and the lock groove 32 vertically communicates with the joint groove 31 (positioning groove 311).

Eight assemblies 40, each of which is disposed opposite each of the recesses 21. In a suitable embodiment, one end of the assembly 40 is threaded to the leg 20 such that the assembly 40 is located in the recess 21 The assembly 40 is slightly a rod body, and includes a connecting rod portion 41, a bolt neck portion 42 and a bolt head portion 43. The joint rod portion 41 and the bolt neck portion 42 can be a round rod. The engaging rod portion 41 extends outward from the inner side of the recessed portion 21, the diameter of the engaging rod portion 41 corresponds to the diameter of the rod connecting groove 12, and the diameter of the plug neck portion 42 is smaller than the engaging rod portion 41. The width of the plug head 43 is approximately equal to the width of the plug neck portion 42. The height (length) of the plug head portion 43 is greater than the diameter of the plug neck portion 42 and less than or equal to the joint rod portion. The diameter of 41 is wide.

Referring to FIGS. 2a and 2b together, when the creation of the expandable shelf structure is combined, the joint side 101 of the joint end portion of the laminate 10 is embedded in the recess 21, so that the joint portion 41 (assembly 40) Correspondingly inserted into the rod receiving groove 12, and the plug head 43 (plug neck 42) enters the bolting groove 13, as shown in Fig. 2a. The plug body 30 is assembled into the bolting slot 13 from the bottom to the top, and the positioning slot 311 (the engaging slot 31) is positioned to receive the bolt head 43, and the bolt neck 42 is correspondingly located. The side of the lock groove 32. The assembly order of the joint rod portion 41 (assembly 40) and the plug body 30 is not limited. After the bolt 30 is rotated by the bolting groove 33 (for example, about 90 degrees), the lock groove 32 is locked and locked to the plug neck portion 42 as shown in FIG. 2b. It is shown that the joint rod portion 41 (assembly 40) is locked and positioned with the plug body 30, so that the layer plate 10 can be firmly assembled on the four-leg column 20. In this embodiment, the inventive expandable shelf structure is combined into a shelf with a two-layer board 10.

Please refer to FIG. 3 and FIG. 4 together, which is a second embodiment of the present invention. The present embodiment can be easily solved by the present embodiment in order to solve the problem that the shelf is intended to increase the number of layers. Therefore, the embodiment is based on the structure of the first embodiment, and the difference is that each of the bonding sides 101 of the layer 10A is provided with four bonding bolt slots 11, that is, adding a combination of two pairs of expansions. The slot 11 is bolted. The four coupling bolt slots 11 are also respectively used for inserting and arranging the engaging rod portion 41 (the assembly member 40) to be coupled with the plug body 30, and wherein the two pairs of the combined bolt slots 11 are borrowed from the original The column 20 is consolidated (same as the first embodiment), and the other two pairs of the combination of the slot 11 are extended The leg 20A is consolidated, that is, the ply 10A is affixed to the recess 21 below the leg 20A by the newly added pair of pegs 11; and the recess 21 above the leg 20A is consolidated. The other layer 10A (the uppermost layer 10A) is similarly provided, and the plug body 30 is provided in the joint pin groove 11 and the insertion joint for providing the assembly 40 is omitted. In this way, the simple arrangement of the four bonding bolt slots 11 on the layer 10A enables the shelf to be expanded into a three-layer shelf by a two-layer shelf, and can be arbitrarily expanded to different requirements. Layers of different layers are relatively simple and quick to operate, and provide considerable economic expansion for both the manufacturing end and the consumer end.

Furthermore, the first embodiment of the present invention expandable shelf improvement structure is shown as a shelf comprising upper and lower two-layer panels 10A, and the second embodiment comprises a shelf of the upper and lower laminates 10 Expanded to form a shelf consisting of three layers of panels 10A (with more than three layers of expansion). In other embodiments, the shelf formed by the upper layer and the lower layer 10 shown in the first embodiment may only be configured to provide the upper layer 10, that is, the lower layer 10 is not required, and the expansion is further performed by the upper layer 10 More than one layer 10A is erected, the technical means and structural features are the same, and the layered pattern is suitable for the application of the bottom layer of the bottom layer to have an appropriate height; of course, at the bottom of the layer is used for touchdown The foot post 20 can be shortened relative to the first embodiment, so that the space below is wasted, and the shelf of the appropriate bottom height can be obtained, which is convenient for various conditions.

The reason is that the creation of the expandable shelf structure can be configured by the simple object layer, and has the effect of rapid assembly and expansion of the number of layers on demand, thereby providing excellent convenience. With the economic benefits of manufacturing assembly.

In summary, this creation has indeed met the requirements of the new patent, and filed a patent application in accordance with the law. However, the above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, the shape, structure, characteristics and spirit described in the scope of the patent application are equally changed and modified. , should be included in the scope of the patent application of this creation.
