The invention discloses a rotating device for fixing a base plate of a wheelchair, which belongs to the technical field of power transmission. The invention includes a rotating shaft for transmitting rotational power, a pair of swing arms symmetrical to the axis of the rotating shaft are installed on the peripheral side of the swing arm section on the rotating shaft, a rectangular stepped hole is opened on each swing arm, and an opposite surface of the swing arm There are guide columns on the top, a pair of annular grooves are opened on the surface of the rotating shaft, and a positioning notch is opened at the end of the rotating shaft. The positioning notch includes a blind hole and a rectangular notch. The rotating shaft is installed between the two shaft seats; One surface is equipped with a clamping plate that matches with the annular groove, and a fan-shaped groove is opened on the shaft seat; a rectangular slot is opened on the shaft seat, and the fan-shaped groove and the rectangular slot are connected through a through hole, and the rectangular slot is installed There is a linear drive. The invention performs load-bearing rotation through the rotating shaft, and has simple control and convenient operation.
Description
technical field [0001] The invention belongs to the technical field of power transmission, in particular to a rotating device for fixing a base plate of a wheelchair. Background technique [0002] In the process of mechanical transmission, especially in the rotary motion, the motor is generally used as the power source for the object, and the motor provides rotation in two cases: one is only to provide rotation power, and the other is to provide high precision. The angular velocity rotation of this method is relatively small, and it cannot provide quantitative rotation control for heavy objects. Contents of the invention [0003] The purpose of the present invention is to provide a rotating device for fixing the base plate of a wheelchair. By limiting the movement of the swing arm on the transmission shaft, and then providing rotation power for the rotating shaft, it is simple and easy to control, and solves the problem of quantitative rotation of heavy objects.
