[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figures 1 to 3 , an expandable table, comprising: a first table board 1, a support plate 11 is fixedly installed at the bottom of one side of the first table board 1, a table leg 12 is fixedly installed at the bottom of the other side of the first table board 1, a second table board 2 is rotatably installed on the table leg 12, the second table board 2 is located below the first table board 1, a bracket 21 is fixedly installed at the bottom of the other side of the second table board 2, and a universal wheel 22 is provided at the bottom of the bracket 21. When in use, the second table board 2 is rotated to rotate the second table board 2 outside the first table board 1, so that expansion can be achieved; conversely, when the second table board 2 is located below the first table board 1, the second table board 2 can be hidden; by changing the rotation angle of the second table board 2, the second table board 2 can be stopped at different positions, thereby changing the overall shape of the table; for example, the second table board 2 is rotated to be perpendicular to the first table board 1, and the table is L-shaped at this time, and can be used as a bar.

[0027] As a limited embodiment, the universal wheel 22 is provided with a brake. The second table top 2 can be stopped at any position by the universal wheel 22 with a brake, but the brake will cause the universal wheel 22 to be larger and not beautiful enough.

[0028] As a preferred embodiment, the universal wheel 22 is embedded in the bottom of the bracket 21 (not shown in the figure), and the bottom of the universal wheel 22 can contact the ground. Compared with the above embodiment, since there is no need to brake the universal wheel 22, the universal wheel 22 can be embedded in the bracket 21, and only a small part of the bottom of the universal wheel 22 is extended outside the bracket 21 to support the bracket 21, which is conducive to improving the overall aesthetics of the table.

[0029] As a preferred embodiment, since the universal wheel 22 in the above embodiment does not have a braking capability, the second table board 2 cannot be positioned and is prone to shaking during use. Therefore, a limit ring 3 is fixedly installed on the table leg 12, and a plurality of limit grooves 31 distributed in a ring array are provided outside the limit ring 3. A clamping rod 4 is slidably installed at the bottom of the second table board 2, and the clamping rod 4 is adapted to the limit groove 31. When the second table board 2 rotates, the second table board 2 can be limited by inserting the clamping rod 4 into the limit groove 31.

[0030] As a preferred embodiment, in order to facilitate the insertion of the clamping rod 4 into the limiting groove 31, a spring 41 is sleeved on the clamping rod 4, and the two ends of the spring 41 are respectively fixedly connected to the second table board 2 and the clamping rod 4. The elastic force of the spring 41 can be used to insert the clamping rod 4 into the limiting groove 31.

[0031] As a preferred embodiment, a connecting rod 42 is fixedly installed at one end of the clamping rod 4, and two levers 43 are symmetrically rotated and installed at the bottom of the second table board 2, and one end of the lever 43 abuts against the connecting rod 42. When one end of the lever 43 is moved, the other end of the lever 43 can push the connecting rod 42 to move, thereby driving the clamping rod 4 to move outside the limiting groove 31, so that the second table board 2 can rotate. Conversely, after releasing the lever 43, the clamping rod 4 can be inserted into the limiting groove 31 under the elastic force of the spring 41. This embodiment can be conveniently operated on either side of the table.

[0032] As a preferred embodiment, a limiting rod 44 is provided at the bottom of the second table top 2. Under the action of the limiting rod 44, the shifting rod 43 can always abut against the left side of the connecting rod 42.

[0033] As a preferred embodiment, an adjusting bolt 13 is provided at the bottom of the table leg 12 .

[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
