As shown in FIGS. 1 and 2 , the springboard 100 includes a board body 110 , two longitudinal beams 120 , 130 and a plug 140 . Wherein, the plate body 110 is a roughly plate-shaped structure, and is a main load-bearing component for carrying people and objects passing through it. The two longitudinal beams 120 , 130 are respectively located on two sides of the board body 110 and extend the entire length of the board body 110 along the longitudinal direction of the board body 110 . The "longitudinal" mentioned herein refers to the length direction of the springboard 100, and the "horizontal" refers to the direction perpendicular to the longitudinal direction. The longitudinal beams 120 , 130 have the same length as the board body 110 , so the longitudinal beams 120 , 130 can extend from one end of the board body 110 to the other end. It can be understood that, under normal circumstances, the longitudinal beams 120, 130 can be located below the bearing surface, or the upper surfaces of the longitudinal beams 120, 130 can be flush with the bearing surface, so that the bearing surface (ie, the upper surface) of the plate body 110 ) is generally flat, thereby facilitating the placement of objects on it or the passage of people and objects over it. However, the orientations described above are only relative. When the springboard 100 is turned upside down from the placement position shown in FIG. The lower surface of the body 110 is flush. But the utility model does not exclude other setting modes other than the above-mentioned setting modes.

In order to improve the rigidity and strength of the diving board 100, the cross-sections of the longitudinal beams 120, 130 are set in a closed shape with a middle cavity.

Those skilled in the art can understand that the design of the beam 150 should consider the requirements of strength, rigidity, overall stability and local stability. In order to make the stress of each section on the springboard 100 uniform, a plurality of beams 150 can be connected between the two longitudinal beams 120 , 130 at the bottom of the board body 110 at equal intervals. The connection between the beam 150 and the longitudinal beams 120 and 130 can be welded well known to those skilled in the art, or can be riveted or bonded. The cross-section of the beam 150 is generally V-shaped with the opening downward, as shown in FIG. 3 . The beam 150 can improve the strength and rigidity of the springboard 100, and the opening of the beam 150 is downward, so that debris is not easy to accumulate.
