Rotational structure for butted panels

Abstract

A rotational structure for butted panels comprises a first panel and a second panel which are connected through a connecting cross bar, wherein grooves and bulges, which are distributed at intervals, are formed in the lower side part of the butted surfaces of the first panel and the second panel; the lower surfaces of the bulges are upwardly concave arc surfaces; when the first panel and the second panel are butted with each other, the bulges on the first panel are embedded into the grooves of the second panels, and the bulges on the second panels are embedded into the grooves of the first panel; besides, the arc surfaces of the bulges fit the outer peripheral surface of the connecting cross bar; the bulges on the first panel and the bulges on the second panel are respectively arranged on the left side and the right side of the connecting cross bar in a holding manner. The rotational structure has the following advantages: the butting parts of the first panel and the second panel are partially superposed, so that the firmness of a butting structure can be favorably improved, and particularly, as the bulges on the first panel and the bulges on the second panel are respectively arranged on the left side and the right side of the connecting cross bar in a holding manner, the structural strength of the panel butting parts can be further improved.

Description

technical field [0001] The invention relates to a rotating structure of a docking panel. Background technique [0002] At present, many furniture products have docking panels that can be folded together, such as a common folding table. When folded, two docking panels can be folded together, and when opened, the two docking panels can be docked with each other to form a table board. Although the folding table has the advantage of smaller volume after folding, it is more convenient to carry, store and transport, but the structural strength of the joints of the panels is low, and it is easy to cause the panels to sag downwards at the joints after being stressed, and the folding table will be damaged in severe cases. table. For example, the butt joint surface of the existing butt joint panels is a flat surface without concave-convex structure. In this way, after the two panels are joined to each other, the front butt seam and the back butt seam of the panels are located on the ...

Problems solved by technology

Although the folding table has the advantage of smaller volume after folding, it is more convenient to carry, store and transport, but the structural strength of the joints of the panels is low, and it is easy to cause the panels to sag downwards at the joints after being stressed, and the folding table will be damaged in severe cases. table

For example, the butt joint surface of the existing butt joint panels is a flat surface without concave-convex structure. In this way, after the two panels are joined to each other, the front butt seam and the back butt seam of the panels are located on the same plane, and the panels cannot bite each other. As a result, the structural strength of the butt joint is low

In addition, when the folding table is used, the structural strength of the joint of the panels is not high, so it is necessary to install a connecting bar on the back of the joint of the panels for support

The existing connecting bars generally use hollow tubes, and the diameter of the entire bar is the same, so that the structural strength at both ends of the bar is relatively low

Moreover, in order to enable the two butt panels to lock each other in use, the connecting crossbar needs to be used in conjunction with the pivoting device. However, since the pipe diameters of the connecting crossbar are the same, the connection installed on the pivoting device The crossbar cannot be limited, and the connecting crossbar after installation is easy to move
