Detailed ways

The technical solutions of the present invention are further described in detail below in conjunction with the preferred embodiments and the accompanying drawings.

Example 1:

As shown in FIGS. 1 to 3, a swimming board corresponding to the first embodiment of the present invention includes a floating body portion 1, a movable mat 18, and a movable assembly 19 connected between the movable mat 18 and the floating body portion 1. The floating body portion 1 has a flat plate shape, which is made of a buoyant material or an inflated structure, is designed to be suitable for a person to crouch on the shape used above, and provides buoyancy for people to swim in the water. The movable assembly 19 can be a standard cross slide or directly connected by two linear guide rails (the cross slide and the linear guide preferably use standard members) so that the movable mat 18 can freely move on the surface of the floating body 1. The movable pad 18 includes a chest pad 22 and an abdominal pad 23 respectively disposed at a position where the chest, the abdomen and the floating body portion 1 of the person are in contact with each other, and the contact layer 28 made of a soft material is attached to the surface of the movable pad 18 to increase the comfort. A receiving portion 24 is formed on the floating body portion 1 at a position corresponding to the chest pad 22 and the abdominal pad 23. The receiving portion 24 is recessed into the upper surface of the floating body portion 1 for mounting the movable assembly 19 so that the chest pad 22 and the abdominal pad 23 are not high. The upper surface of the floating body portion 1 is excessive.

When the person's body is squatting on the swimming board, the hands and feet are stretched into the water to draw water for swimming practice, the body will be twisted. If the body directly rubs against the floating body 1, the comfort will be reduced or even the skin will be scratched. 22 and the abdominal pad 23, when the body is twisted, the chest pad 22 and the abdominal pad 23 will follow the body Working together, reducing friction, and making it easier for people to practice the force in the water, in addition, the surface of the chest pad 22 and the abdominal pad 23 is attached with a soft elastic material, and the contact is more comfortable. Because it is used on the swimming board, after being tired, you can rest on the swimming board, and there will be no accidents such as drowning after physical exertion, and the safety is higher.

Example 2

As shown in Figs. 4 to 5, corresponding to the second embodiment of the present invention, the floating body portion 1 is modified into a foldable structure based on the structure of the first embodiment. In the present embodiment, the floating body portion 1 includes a front floating body portion 1a and a rear floating body portion 1b.
