Description

Technical Field

[0001] This utility model relates to the technical field of tables, and in particular to a table with an interchangeable top and bottom surface. Background Technology

[0002] A table is a common household item with various structural styles. The basic structure includes a tabletop and legs supporting it. To increase the table's load-bearing capacity, a platform is sometimes added to the tabletop. However, the existing platform on most tables remains fixed above the tabletop and cannot be moved, thus failing to meet the user's need to place items on the tabletop. Utility Model Content

[0003] This invention provides a table with a platform that can be selectively installed above or below the desktop, allowing the platform to be interchanged, thus solving the problem that the platform of existing tables can only be kept on the desktop at all times.

[0004] The above technical problems are solved by the following technical solution: a table with an interchangeable tabletop, comprising a tabletop and table legs supporting the tabletop, characterized in that it further comprises a first loading platform and a platform connecting frame connecting the first loading platform to the tabletop. The platform connecting frame includes a first front-rear connecting rod and a vertical connecting rod with one end connected to the first front-rear connecting rod. The first loading platform is connected to the other end of the vertical connecting rod, and the horizontal connecting rod is detachably connected to the tabletop. In use, the first front-rear connecting rod can be flipped as needed, so that the first loading platform is positioned above or below the tabletop for loading. The loading platform increases the table's load capacity and allows for changing the position of the loading platform.

[0005] Preferably, the front and rear connecting rods are connected to the desktop via connecting bracket fixing bolts, which facilitates installation and disassembly.

[0006] Preferably, two metal connecting plates extending laterally and laterally are fixed to the lower surface of the desktop. Two connecting bracket fixing bolts pass through the first forward-backward connecting rod and are threaded onto the two metal connecting plates in a corresponding manner. These connecting bracket fixing bolts are threaded onto the lower surface of the desktop. This design allows for reliable fixing of the first forward-backward connecting rod even when the desktop is made of a loose material.

[0007] Preferably, the metal connecting piece is fixed to the lower surface of the desktop by connecting piece fixing bolts. This results in a neat and tidy appearance.

[0008] Preferably, the other end of the vertical connecting rod is connected to a second forward / backward connecting rod, and the first platform is detachably connected to the second forward / backward connecting rod via platform fixing bolts. This improves the reliability of the connection between the first platform and the vertical connecting rod.

[0009] Preferably, the vertical connecting rod includes a first section with one end connected to a first forward-backward connecting rod and a second section with one end retractably connected to the other end of the first section. The first platform is connected to the other end of the second section, and a positioning structure is provided between the first section and the second section to fix the first section and the second section together. This makes the height of the vertical connecting rod adjustable, thereby changing the height of the first platform.

[0010] Preferably, one end of the second segment is retractably inserted into the other end of the first segment. The positioning structure includes a threaded hole on the first segment and a locking bolt threaded into the threaded hole to hold the second segment in place. In use, the connection between the first and second segments is fixed and loosened by rotating the locking bolt.

[0011] Preferably, the table also includes a left-right rotating shaft and a lifting motor that drives the left-right rotating shaft. The table has two legs distributed along the left-right direction. Each leg includes an upper section whose upper end is fixed to the lower surface of the tabletop and a lower section whose upper end passes through the lower end of the upper section. The lower end of the lower section is connected to a front-back support rod. The upper and lower sections are fitted with a prism-shaped surface. The upper section contains a vertical threaded rod that rotates via the rotating shaft. The rotating shaft and the vertical threaded rod are connected by gears. The lower section contains a threaded sleeve that is threadedly connected to the vertical threaded rod. This allows for adjustable tabletop height.

[0012] Preferably, the rear side of the first platform is provided with a guardrail to prevent objects from falling behind the table.

[0013] Preferably, the desktop is also supported by a support rod for a second carrying platform. When the first carrying platform is above the desktop, the second carrying platform is below the first carrying platform. Baffles are provided on the two rear corners of the desktop, and hooks are provided on the lower surfaces of the left and right ends of the desktop.

[0014] This utility model has the following advantages: the carrying platform has a large carrying capacity; the carrying platform can be adjusted to be located above or below the desktop to meet different carrying needs; the height of both the desktop and the carrying platform can be adjusted.
