[0002] An existing patent (publication number: CN112841887A) proposes a dining table system, including: a table body, a fixed tabletop, a first motor, a placement layer, and a rotating tabletop. The fixed tabletop is located at the top of the table body, and the placement layer is located at the top of the table body. The rotating tabletop is located above the placement layer. One end of an annular support column is connected to the bottom of the rotating tabletop, and the other end of the annular support column is rotatably connected to the bottom of the placement layer via a roller guide rail assembly. An annular rack is provided on the inner sidewall of the annular support column. The first motor is located at the bottom of the placement layer, and the output end of the first motor is connected to a drive gear. The drive gear meshes with the annular rack. However, this dining table cannot be folded when not in use, occupies a large area, and is inconvenient for transportation and storage. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a tabletop support structure that allows for sliding and swivel support to be close to rotating support during use. This allows the tabletop to be rotated and folded to the sides of the two supports, making the entire table more convenient to store. It also prevents the tabletop from tilting during use, resulting in a highly stable tabletop support structure.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A highly stable dining table support structure includes a tabletop, a lower connecting lug, vertical legs, a first connecting rod, a movable leg, a second connecting rod, an upper support beam, a rotating block, an upper rotating connecting plate, a lower rotating connecting plate, and a side connecting plate. The lower connecting lug is connected to the lower part of the tabletop. The first connecting rod is connected to the side of the vertical legs, which are symmetrically arranged on both sides of the first connecting rod. The upper side of the vertical legs fits into the lower connecting lug, and the upper part of the vertical legs is connected to the lower connecting lug via a first rotating shaft. The lower surface of the upper rotating connecting plate fits into the lower rotating connecting plate, which is connected to the lower rotating connecting plate via a third rotating shaft. The movable leg is connected to the side of the second connecting rod, and the movable leg is symmetrically arranged on both sides of the second connecting rod. The upper part of the movable leg is connected to the upper support beam, which has a storage groove. The rotating block is adapted to the storage groove and is inserted into the storage groove.

[0006] The rotating support block is connected to the upper support beam through the second rotating shaft. A set of rotating support blocks are symmetrically arranged on the upper support beam. The upper surface of the rotating support block is in contact with the lower surface of the dining table. The upper part of the second connecting rod has a fifth connecting lug, and the lower part of the second connecting rod has a fourth connecting lug. The upper part of the first connecting rod has a second connecting lug, and the lower part of the first connecting rod has a third connecting lug.

[0007] One end of the upper rotating connecting plate is connected to the No. 5 connecting trunnion, the other end of the upper rotating connecting plate is connected to the No. 2 connecting trunnion, one end of the lower rotating connecting plate is connected to the No. 4 connecting trunnion, and the other end of the lower rotating connecting plate is connected to the No. 3 connecting trunnion. Beneficial effects

[0008] 1. In this utility model, the two ends of the first connecting rod are connected to symmetrical vertical support legs, forming a rotating bracket. The upper part of the vertical support legs is connected to the lower connecting ear through the first rotating shaft, so that the upper part of the rotating bracket is connected to the tabletop of the dining table, allowing the tabletop to rotate relative to the rotating bracket. The second connecting rod, the movable support leg, and the upper support beam form a movable bracket, which is placed under the tabletop of the dining table and works with the rotating bracket to support the tabletop. The rotating support block is connected to the upper support beam through the second rotating shaft, allowing the rotating support block to rotate. In use, the rotating support block can be rotated so that its upper surface is in contact with the tabletop of the dining table. The movable bracket supports the tabletop of the dining table through a set of rotating support blocks, and works with the rotating bracket to keep the tabletop of the dining table horizontal. The tabletop of the bracket is highly stable and prevents it from tilting during use.

[0009] 2. The upper and lower rotating connecting plates of this utility model form a cross frame. The two ends of the cross frame are connected to the shafts of the first and second connecting rods, respectively, so that the rotating bracket and the moving bracket form a linkage structure, ensuring the alignment of their lower surfaces. A set of side connecting plates are connected to the shafts of the vertical support legs and the moving support legs, assisting the cross frame in limiting the movement of the moving bracket and ensuring the parallelism of the moving bracket and the rotating bracket. The connection between the lower part and the sides of the rotating bracket and the moving bracket ensures their integrity. At the same time, the side connecting plates limit the maximum distance between the rotating bracket and the moving bracket, preventing the moving bracket from sliding out from the bottom of the tabletop during use. When in use, the moving bracket and the rotating bracket can be slid close together, and the tabletop can be rotated and folded to the sides of the two brackets, making the entire table more convenient to store.
