The rotating bed body is rotatably installed on one side of the top of the main bed body, the first electric push rod is movably installed on the other side of the bottom of the main bed body, the second electric push rod is movably installed on the side of the bottom of the main bed body close to the rotating bed body, and the third electric push rod is movably installed inside the push rod frame. The push rod frame is fixedly connected to both sides of the rotating bed body. The side of the bottom of the main bed body close to the rotating bed body is rotatably connected to the top bed rod, and the end of the top bed rod away from the main bed body is slidably connected to the rotating bed body. However, this device "the bottom four corners of the main bed body are provided with bed feet", in which the equipment relies on the bed feet to support the nursing bed. If the direction of the internal personnel needs to be rotated, the operator needs to move the nursing bed as a whole, which is inconvenient to use and affects the working efficiency of the equipment. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a worm motor on the side of the center bracket that drives the worm wheel to rotate, so that the worm wheel drives the gear on the side of the center bracket to rotate, and at the same time, the center bracket drives the bed board to rotate, so that the device can adjust the direction of the bed board according to actual needs without moving the entire device, thereby increasing the working efficiency of the device, and protecting the personnel inside the bed board through the guardrails on the sides of the bed board. When the guardrails need to be folded up, the positioning pins on the sides of the guardrails are pulled to disengage the positioning pins from the pin grooves and release the blocking positioning of the guardrails, so that the device can retract and release the guardrails according to actual conditions, thereby increasing the adaptability of the device to provide an easily adjustable nursing bed.

Beneficial Effects

[0008] 1. During the use of the nursing bed which is easy to adjust, the worm motor on the side of the central bracket drives the worm wheel to rotate, so that the worm wheel drives the gear on the side of the central bracket to rotate, and at the same time, the central bracket drives the bed board to rotate, so that the device can adjust the direction of the bed board according to actual needs without moving the entire bed, thereby increasing the working efficiency of the device.

[0009] 2. During the use of the nursing bed which is easy to adjust, the guardrails on the sides of the bed board are used to protect the personnel inside. If the guardrails need to be folded up, the positioning pins on the sides of the guardrails are pulled to disengage the positioning pins from the pin grooves, thereby releasing the blocking positioning of the guardrails. The guardrails can be folded and extended according to actual conditions, thereby increasing the adaptability of the equipment.

[0010] 3. During the use of the nursing bed which is easy to adjust, the worm motor on the side of the central bracket drives the internal worm to drive the worm wheel to rotate. Since the transmission principle of the worm and the worm motor has a self-locking function, it prevents accidental rotation when a person moves on the upper part of the bed board, thereby enhancing the stability of the equipment.
