[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] This embodiment provides a stackable table that can be used as any one of a desk, a desk, an office desk or a dining table. Figure 1 and Figure 2The stackable tableware comprises: a table frame 10 and a table top 20 arranged on the table frame 10; the table legs 11 of the table frame 10 are tapered columns with an outer diameter gradually decreasing from top to bottom, the tapered columns are provided with tapered grooves 111, the tapered grooves 111 extend downward from the top of the tapered columns along the length direction of the tapered columns, and the inner diameter of the tapered grooves 111 gradually decreases from top to bottom, and the inner diameter of at least part of the tapered grooves 111 is greater than the outer diameter of at least part of the tapered columns; since the inner diameter of the tapered grooves 111 and the outer diameter of the tapered columns are different The height positions of the conical grooves 111 are different, and the size change mode of the two is gradually reduced from top to bottom. Therefore, the position where the inner diameter of the conical groove 111 is the largest is the top end, and the position where the inner diameter is the smallest is the bottom end. The position where the outer diameter of the conical column (i.e., the table leg 11) is the largest is the top end, and the position where the outer diameter is the smallest is the bottom end. The purpose of setting the inner diameter of at least part of the conical groove 111 greater than the outer diameter of at least part of the conical column in this embodiment is to make it easier to stack two stackable table sets together. The stacking method can be as follows: Fig. 9 As shown, stackable tableware can be stacked together for easy transportation and storage; as long as the inner diameter of at least part of the conical groove 111 is larger than the outer diameter of at least part of the conical column, it can be ensured that the lower part of one conical column can be inserted into the conical groove 111 of another conical column, thereby achieving the following effect: Fig. 9 In the stacking method shown, the depth of the tapered groove 111 in which one tapered column can be inserted into another tapered column can be designed according to the requirements. In order to minimize the space occupied after stacking, the interval between the two table tops 20 can be reduced as much as possible. The smaller the interval between the table tops 20 of the two stackable table sets, the smaller the space occupied. The table legs 11 are set as tapered columns and tapered grooves 111 are provided. When the table legs 11 of the two stackable table sets are put together, the whole is very stable and will not shake during transportation and movement, thereby improving the convenience of transportation. In addition, for idle stackable table sets, stacking them can reduce the space occupied. Since the whole is very stable, there is no safety hazard during storage.

[0033] In order to prevent the table top 20 from blocking the top entrance of the conical groove 111, the top of the conical groove 111 is not covered by the table top 20. Figure 3 As shown, the four corners of the table top 20 are all provided with inwardly concave chamfers. If the inwardly concave chamfers are not provided, the area of ​​the table top 20 can be reduced, or the table legs 11 can be arranged at a more outward position to ensure that the top of the conical groove 111 is not covered by the table top 20.

[0034] In one embodiment, the periphery of the table top 20 is formed with a plurality of inwardly concave chamfers, and the chamfers correspond to the conical columns one by one. The top of the conical groove 111 is located in the corresponding chamfer. The utilization rate of the corner position of the table top 20 is low and it is easy to hurt people. The table legs 11 are arranged at this position, which cleverly solves two problems at the same time. The inwardly concave chamfers are arc chamfers, and their size can be slightly larger than the outer diameter of the top of the table legs 11. This structure can ensure that the table legs will not exceed the rectangular plane of the table top 20, and it is easy to realize the seamless splicing of the table tops 20 and the multiple stackable tablewares spliced ​​together. Figure 7 and Figure 8 As shown, there is a three-dimensional schematic diagram of four stackable tables put together.

[0035] In one embodiment, the conical groove 111 runs through from the top of the conical column to the bottom of the conical column, so that the conical column becomes a tubular structure, and a baffle 112 is provided in the conical groove 111. The inner diameter of the position of the baffle 112 in the conical groove 111 is greater than or equal to the minimum outer diameter of the conical column. The baffle 112 can limit the stacking position of the stackable tableware above, so as to avoid the situation that the nesting is too firm and causes inconvenience in use.

[0036] In one embodiment, see Fig.10 At least part of the conical groove 111 is provided with a strip notch 113, which extends downward from the top of the conical groove 111; the top opening of the conical groove 111 and the top of the strip notch 113 are smoothly transitioned through the curved surface 114. By providing the strip notch 113, the inner diameter of the same position of the conical groove 111 can be slightly changed when necessary, for example, when multiple stackable tablewares are stacked. Fig. 9 When stacking, the upper leg 11 of the stackable table set may squeeze the conical groove 111, causing the lower leg 11 to deform and enlarge the inner diameter of the conical groove 111. The presence of the strip notch 113 makes this change more flexible, which can effectively avoid the problem of two stackable table sets getting stuck and difficult to pull out after being stacked together.

[0037] In one embodiment, the width of the strip notch 113 gradually decreases from top to bottom. The strip notch 113 cooperates with the curved surface 114 to make the stackable table more beautiful, and because the outer diameter of the tapered column is larger, the width of the strip notch 113 at this position can provide sufficient support strength even if it is larger, thereby ensuring the overall structural strength of the stackable table.

[0038] See also Figure 1-Figure 6 The table frame 10 includes a crossbeam frame 12 and a tapered column (i.e., table leg 11), the tapered column is fixed to the crossbeam frame 12, and the table top 20 is laid on the crossbeam frame 12. Figure 2As shown, the table frame 10 includes two cross beam frames 12 and four tapered columns. Specifically, a table frame 10 can be composed of two identical table frame units, such as Figure 6 As shown, it shows half a table frame 10 (i.e., a table frame unit). The two parts can be connected by bolts or welding. During production, only the table frame unit needs to be produced, and then a complete table frame 10 can be formed through assembly. A single table frame unit is easier to process and transport.

[0039] In one embodiment, there are two crossbeam frames 12, which are symmetrically arranged, and a conical column is fixedly connected to both ends of each crossbeam frame 12. That is, the table frame 10 is composed of two table frame units with exactly the same shape, which are symmetrically arranged and combined to ensure the standardization and efficiency of production and save finished products. At the same time, it can be effectively stacked for easy transportation. The table frame 10 can also be designed with other structural solutions according to needs, which will not be specifically introduced here.

[0040] In one embodiment, the two cross beams 12 are both "C" shaped, and the middle areas of the two cross beams 12 are close together. The "C" shape here represents a general outline and is not required to be exactly the same as the letter shape.

[0041] The table top 20 can be set to be circular, square, triangular or other polygonal shapes according to the needs. In this embodiment, a rectangular table top 20 is selected to facilitate multiple stackable tableware such as Figure 7 Splicing shown.

[0042] See also Figure 1-Figure 6 , each crossbeam frame 12 is provided with a hanging basket 121, and the hanging basket 121 is located below the table board 20. The hanging basket 121 can hang personal belongings such as school bags, and maximize the function in this most effective and direct way. The hanging basket 121 can be set as a hollow structure, and the hollow hanging basket form can also prevent the loss and forgetting of personal belongings; for students who often use computers, the design of the hanging basket 121 provides a placement for the power strip and power supply, avoiding placing the corresponding electrical appliances on the desktop to affect the usable area, and also preventing it from being placed on the ground to cause safety problems; the hanging basket 121 can be a completely independent component, which can be hung at any position under the desktop according to needs.

[0043] In one embodiment, the connection position between the cross beam frame 12 and the tapered column is lower than the top of the tapered column, so that when the table top 20 is laid on the cross beam frame 12, the upper surface of the table top 20 is flush with the top of the tapered column. Thus, the upper surface of the table top 20 can smoothly transition with the top of the tapered column, reducing the problem of scratches and bumps.
