Detailed Description

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 3, an angle-adjustable rotating apparatus for an electric nursing bed according to the present embodiment includes:

a lower fixed seat 1;

the upper rotating seat 2 is arranged above the lower fixing seat 1 and rotates horizontally relative to the lower fixing seat;

the rotating shaft 3 penetrates through the upper rotating seat 2, and the lower end of the rotating shaft 3 is fixedly connected with the lower fixed seat 1;

the motor 4 is fixedly connected to the upper rotating seat 2, and an output shaft of the motor 4 is in transmission connection with the rotating shaft 3;

and a support bracket 5 provided on the upper rotating base 2.

Wherein, the support bracket 5 is used for installing and fixing a bed body to be horizontally rotated.

In this embodiment, the output shaft of motor 4 is fixed on fixing base 1 down, gives motor 4 circular telegram, because the output shaft is fixed, can't realize rotating, and makes motor 4 fuselage rotate, and the 4 fuselage of motor is fixed on fixing base 1 pivoted upper rotating base 2 down relatively, causes motor 4 fuselage to take upper rotating base 2 horizontal rotation, drives the bed body of installing on supporting bracket 5.
