[0002] In the healthcare sector, nursing beds are essential equipment for assisting patients in their daily lives, treatment, and rehabilitation. Their design and functionality are directly linked to patient comfort, recovery outcomes, and the efficiency of medical staff. Traditional nursing beds, with their limited functionality like lifting and tilting, struggle to meet diverse and personalized care needs. This limitation is particularly evident in scenarios where frequent adjustments to the patient's position are required to promote blood circulation, prevent pressure ulcers, assist with breathing, or perform specific rehabilitation exercises.

[0003] The reference patent is titled "A Nursing Bed" (publication number CN215960711U), and comprises: a bed body having an assembly hole; a guardrail having a connecting tube disposed in the assembly hole; and a locking mechanism comprising a locking member and a trigger member. The locking member is disposed in the connecting tube, the locking member having a locking portion, the locking portion being passed through the connecting tube and maintained in a locking position for locking the bed body; the trigger member being passed through the connecting tube and abutting against or connected to the locking member; and the trigger member being triggered to drive the locking portion to move away from the locking position. The bed body and the guardrail can be assembled by means of a hole-shaft fit, making assembly more reliable. The provision of a locking mechanism facilitates locking and unlocking of the bed body and the guardrail, enabling quick installation or removal of the guardrail. The coordinated cooperation of the assembly hole, the connecting tube, and the locking mechanism makes the connection between the guardrail and the bed body more reliable and stable.

[0004] In recent years, with the continuous advancement of medical technology and the increasing demand for patient care, various types of nursing beds with different functions have gradually appeared on the market, such as the detachable nursing bed mentioned in the above patent, as well as nursing beds with adjustable angles. However, these products are often limited to adjustment in one or a few directions, such as only being able to raise or lower the head or foot of the bed, and cannot fully meet the diverse needs of patients at different stages of treatment or living conditions. To this end, the present utility model provides a nursing bed with multi-directional angle adjustment. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a nursing bed with multi-directional angle adjustment, which solves the problem that although there are nursing beds with adjustable angles on the market, these products are often limited to adjustment in one direction or a few directions, such as only being able to raise or lower the head or foot of the bed, and cannot fully meet the diverse needs of patients in different treatment stages or living conditions.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a nursing bed with multi-directional angle adjustment, comprising a bed frame, wherein an angle adjustment mechanism is provided at the lower end of the bed frame, and the angle adjustment mechanism includes:

[0007] The turning assembly is arranged at the lower part of the bed frame, including a transmission rod rotatably mounted on the lower end of the bed frame, and turning rods are fixed on both sides of the transmission rod, and a motor is fixedly mounted on one end of the bed frame, and the power output end of the motor is connected to the power input end of the transmission rod;

[0008] The limiting component is arranged at the lower part of the bed frame and is used to limit the flip angle of the flip rod; the protective component is arranged on both sides of the bed frame and is used to protect one side of the bed frame.

[0009] Preferably, the limiting assembly includes two groups of rod sleeves fixedly installed on the lower end of the bed frame, and the inner sides of the two groups of rod sleeves are provided with sliding rods that can slide and retract, and racks are fixed between the sliding rods. A gear is meshed and installed at the lower end of the rack, and the gear is connected to the transmission rod.

[0010] Preferably, the protection assembly includes an L-shaped connecting rod fixedly connected to the lower end of the sliding rod, and one end of the L-shaped connecting rod is fixedly connected to a right-angle plate.

[0012] Preferably, two groups of shafts distributed parallel to each other are welded to the bed frame, and flip plates are rotatably mounted on both groups of shafts.

[0013] Preferably, a plurality of groups of cross bars distributed parallel to each other are welded to the lower end of the bed frame, and four groups of rollers capable of assisting the movement of the bed frame are installed at the bottom end of the bed frame.

[0014] Beneficial effects

[0015] The utility model provides a nursing bed with multi-directional adjustable angle. Compared with the existing technology, it has the following advantages:

[0016] (1) The multi-directionally adjustable angle nursing bed is designed with a flip assembly. After the motor is started, its rotational power is transmitted to the transmission rod, causing the transmission rod to rotate around its installation axis. Flip rods are fixed on both sides of the transmission rod. As the transmission rod rotates, the flip rod will correspondingly drive the left and right flip plates on the bed frame to flip, thereby achieving angle adjustment. When the transmission rod rotates, the gear and rack engage to control the telescopic distance of the slide rod in the rod sleeve, thereby limiting the flip angle of the flip rod and achieving angle control.

[0017] (2) The multi-directionally adjustable angle nursing bed is designed with a protective component. When the flip rod drives the flip plate to flip, the L-shaped connecting rod moves with the movement of the sliding rod, and the right-angle plate acts as a guide or limiting component and contacts the inclined surface of the resistance rod. The resistance rod is slidably installed on the inner wall of both sides of the bed frame, and an armrest is fixed on the top of the resistance rod. When the patient on the nursing bed flips to one side, it provides a side blocking structure to prevent the patient from falling off the bed. BRIEF DESCRIPTION OF THE DRAWINGS
