Description

Field

[0001] The present disclosure relates to the field of sports apparatus, and in particular to a multifunctional training device.

Background

[0002] The balance plate is an important exercise apparatus for training sensitivity and balance.

[0003] A ball-type balance plate disclosed by the patent "A ball-type balance plate" (publication number: CN210612785U) includes a pedal bottom plate and an elastic ball body installed at the bottom of the pedal bottom plate. The elastic body is connected with a mounting hole through a protection seat. The elastic ball body is an inflatable ball. The surface of the ball body has a cylindrical protruding mounting boss, and the neck of the mounting boss contracts to form a contraction part. A fixed round hole is arranged in the center of the protection seat. When the elastic ball body is not inflated, the mounting boss of the elastic ball body is squeezed into the fixed round hole. After the elastic ball body is inflated, the contraction part is clamped in the fixed round hole to form a fixation. The protection seat is circular. The protection seat is installed in the mounting hole of the pedal bottom plate through a conventional axial hole connection mode such as thread connection, buckle connection, etc., to form a fixation between the elastic ball body and the pedal bottom plate. Once the interference of the conventional axial hole connection modes such as thread connection, buckle connection, etc. is worn, the tightness of the connection between the elastic ball body and the pedal bottom plate cannot be guaranteed. At the same time, the device described in the patent can be used as a ball-type balance plate as much as possible. When exercising, the person stands on the pedal bottom plate, pulls corresponding tension tubes with both hands, jumps up and down to exercise balance, and the use mode is single.
