[0002] A nursing bed is a medical device used to provide healthcare services and nursing care, and is usually used in places such as hospitals, clinics, nursing homes, and families. Nursing beds are more suitable for patients who are bedridden for a long time because they can adjust the height, angle, and position to meet the various needs of patients.

[0003] The currently used nursing beds usually adopt a lead screw structure to adjust the bed body. By turning the handle, the positions of the back and legs of the bed body can be adjusted to an inclined angle. This adjustment method is relatively stable and can slowly adjust the angle of the bed so that it can be conveniently adjusted to a comfortable angle for the human body. However, the above adjustment method is relatively slow, and the adjustment structure will get stuck, resulting in difficult adjustment. In view of the above problems, a solution is proposed below.

The middle bracket is fixed on the bottom bracket. A folding hinge is provided on one side of the middle bracket. The leg bracket is located on one side of the middle bracket and is connected to the folding hinge. The leg bracket changes the angle with the middle bracket through the folding hinge, and the folding hinge is used to fix the leg bracket after the angle adjustment so that the leg bracket remains in an inclined state.

[0007] Preferably, a small bracket is provided on the side of the leg bracket away from the middle bracket. The width of the small bracket is smaller than that of the leg bracket. Two connecting blocks are fixed on the leg bracket. Connecting grooves are provided on the connecting blocks. Two sides of the small bracket are respectively inserted into the two connecting grooves and are rotatably connected to the connecting blocks through fasteners. The depth of the bottom of the connecting groove extending to the connecting block is less than that of the top. The bottom of the connecting groove is used to press against one side of the small bracket so that the small bracket is fixed at an inclined angle.

[0008] Preferably, a handle is fixed on one side of the leg bracket. The handle extends horizontally to the outside of the bottom bracket, and the handle is used to adjust the leg bracket.

[0009] Preferably, a wire frame is fixedly provided on the upper end surface of the middle bracket, and the wire frame is used to improve the bearing capacity of the middle bracket.

[0010] Preferably, the adjusting frame further includes a back bracket. One side of the back bracket is rotatably connected to the bottom bracket. An electric push rod is provided on the back bracket. The body of the electric push rod is hingedly connected to one side of the back bracket, and the output shaft of the electric push rod is hingedly connected to the bottom bracket. The electric push rod is used to push the back bracket so that the back bracket can be inclined with respect to the bottom bracket.

[0011] Preferably, when the back bracket is in the flat state, the position of the body part of the electric push rod is higher than the position of the end of the output shaft of the electric push rod.

[0012] The beneficial effects of the present utility model are as follows: When adjusting the back of the nursing bed, it is pushed by an electric push rod, and manual adjustment is not required, so that the back bracket can be adjusted conveniently and quickly. The adjustment of the leg bracket is manual. By holding the handle, the leg bracket can be lifted. When the leg bracket is lifted to a certain angle, the folding hinge can fix the leg bracket at this angle. When the leg bracket is adjusted to be inclined, the side of the small bracket away from the leg bracket will naturally droop under the action of gravity, so that a herringbone shape is formed between the leg bracket and the small bracket, which can support the legs of the human body and keep the human body comfortable.

[0017] Such as Figure 1 and Figure 2As shown in the figure, a conveniently adjustable nursing bed frame includes a bottom bracket 1 and an adjustment bracket. The adjustment bracket is located on the upper end surface of the bottom bracket 1 and is connected to the bottom bracket 1. The bottom bracket 1 can be used as the bracket of the nursing bed or be fixedly connected to the bracket of the nursing bed.

[0018] The adjustment bracket includes a back bracket 10, a middle bracket 2, and a leg bracket 3. One side of the back bracket 10 is rotatably connected to the bottom bracket 1, and the back bracket 10 can rotate around the connection point. An electric push rod 11 is provided on the back bracket 10. The body of the electric push rod 11 is hingedly connected to one side of the back bracket 10, and the output shaft of the electric push rod 11 is hingedly connected to the bottom bracket 1. After the electric push rod 11 is started, it will drive one side of the back bracket 10 to make a circular motion around the connection point, so that the back bracket 10 is inclined relative to the bottom bracket 1 to realize the support for the human back. The inclination angle of the back bracket 10 is adjusted by the electric push rod 11, and a remote control can be set to control the electric push rod 11. The electric push rod 11 in this design can also be replaced by other components or structures that can provide linear power, such as air cylinders, linear motors, screw structures, etc.

[0019] The initial state of the back bracket 10 is the state when it is laid flat on the upper end of the bottom bracket 1. In the initial state, the position of the body part of the electric push rod 11 is higher than the position of the end of the output shaft of the electric push rod 11. Therefore, when the output shaft of the electric push rod 11 starts to extend, the body part of the electric push rod 11 can push one side of the back bracket 10 upward. The electric push rod 11 can also support the back bracket 10 to fix the back bracket 10 in an inclined state.

[0020] The middle bracket 2 is fixed on the bottom bracket 1, and the middle bracket 2 is parallel to the bottom bracket 1, that is, the lower end of the middle bracket 2 is completely attached to the upper end surface of the bottom bracket 1. The middle bracket 2 is fixed to the bottom bracket 1 by welding or fixing with fasteners, etc., so that the middle bracket 2 has good stability. A net rack 9 is fixedly provided on the upper end surface of the middle bracket 2. The position where the middle bracket 2 is located is the hip area of the human body. When maintaining a sitting position, this area is the main stress point. Therefore, by improving the bearing capacity of the middle bracket 2 through the net rack 9, the bed frame can be made more durable.

[0021] A folding hinge 4 is provided on one side of the middle bracket 2. The leg bracket 3 is located on one side of the middle bracket 2 and is connected to the middle bracket 2 through the folding hinge 4. The folding hinge 4 is a commonly used hinge in existing equipment. The folding hinge 4 can fix the leg bracket 3 after angle adjustment to keep the leg bracket 3 in an inclined state. According to requirements, a multi-gear folding hinge 4 can also be selected to enable the leg bracket 3 to have multiple inclined angles.

[0022] One side of the leg support 3 is fixedly provided with a grip 8. Taking the length direction of the bed frame as the longitudinal direction and the width direction as the transverse direction, the grip 8 is located on one side of the leg support 3 and is arranged transversely. The grip 8 is located above the bottom support 1 and extends transversely to the outside of the bottom support 1. When adjusting the leg support 3, by holding the grip 8, a force can be conveniently applied to the leg support 3, thereby changing the state of the leg support 3.

[0023] A small support 5 is provided on the side of the leg support 3 away from the middle support 2, and the width of the small support 5 is smaller than the width of the leg support 3.
