detailed description

The utility model will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the following description of the utility model with reference to the accompanying drawings is only illustrative and not restrictive. Different embodiments can be combined with each other to form other embodiments not shown in the following description.

Referring to FIGS. 1-5 , a push-up board is provided in an embodiment of the present invention, including: a left support board 1 , a right support board 2 and a folding device 3 . The folding device 3 includes a left rotating member 31 and a right rotating member 32 which are rotationally connected, the left rotating member 31 is fixedly connected to the lower side of the left support plate 1, the right rotating member 32 is connected to the The lower side of the right support plate 2 is fixedly connected, and after folding, the lower side of the left support plate 1 and the lower side of the right support plate 2 abut against each other.

For the convenience of description, based on the perspective of the top view of the push-up board, the axis passing through the middle of the left support board 1 and the right support board 2 in the horizontal direction is called the horizontal axis, and the axis passing through the middle of the right support board 2 in the vertical direction is The axis in the middle of the left support plate 1 and the right support plate 2 is called a vertical axis.

In a preferred embodiment, the shapes of the left support plate 1 and the right support plate 2 may be arranged symmetrically along the vertical axis, and may also be asymmetrically arranged in other embodiments. In the unfolded state of the push-up board, one end of the left support board 1 and one end of the right support board 2 are abutted against each other. Of course, in other embodiments, the adjacent ends of the left support plate 1 and the right support plate 2 may also be arranged at intervals.

In a preferred embodiment, the left support plate 1 and the right support plate 2 both include a planar portion 14 and a support portion 15, the planar portion 14 extends in a horizontal direction, and the support portion 15 extends in a vertical direction The support portion 15 is extended, and the support portion 15 is located on the lower side of the planar portion 14 . The shape of the support portion 15 is adapted to the shape of the outer surface of the planar portion 14, and the upper end of the support portion 15 is fixedly connected with the outer surface of the planar portion 14, preferably integrally formed. The lower end of the support portion 15 abuts against the ground, and the planar portion 14 is spaced apart from the ground.

Since the planar portion 14 is extended in the horizontal direction and the support portion 15 is extended in the vertical direction, in order to reduce the sharp connection between the planar portion 14 and the support portion 15, the user will Risk of injury due to collision. Therefore, both the left support plate 1 and the right support plate 2 also include an inclined portion 16 , and the inclined portion 16 is arranged at an included angle with the horizontal direction. And the inclined portion 16 is located between the planar portion 14 and the support portion 15 , and the shape of the inclined portion 16 is adapted to the outer surface of the planar portion 14 .
