The side-turning component of the nursing bed can be improved: the upper ends of the connecting rods are not required to be arranged on the inclined platform, and if the upper end of one connecting rod is arranged on the bed plate of the left middle bed plate mechanism and the upper end of the other connecting rod is arranged on the bed plate of the right middle bed plate mechanism, a power source can be provided for overturning the left middle bed plate mechanism and the right middle bed plate mechanism. Of course, the number of the side turning components can be increased, so that the side turning components are arranged between the bed seat and the left back bed board mechanism, the right back bed board mechanism, the left middle bed board mechanism, the right middle bed board mechanism, the left front bed board mechanism and the right front bed board mechanism, and the side turning function of the bed is realized.
The above-mentioned telescopic device may be a linear motion type member such as a cylinder, an electric push rod, a telescopic rod, or the like.
The multifunctional nursing bed can help the user to lean on and support the back, and the nursing bed can be integrally deformed into a wheelchair, so that the patient can go out conveniently. The roll-over function of the nursing bed is illustrated as follows: as shown in the combination of fig. 13 and 14, the nursing bed side turning components of the invention are distributed in a rectangular shape, when the retractors of the side turning components of the two left groups extend, the middle bed board mechanism inclines rightwards, thereby driving the nursing bed to integrally turn rightwards, and realizing the function of turning sideways. The back support function of the nursing bed is described as follows: and in combination with the figures 10 and 11, the telescopic device of the inclination assembly is pushed to extend, and the end cover supports the telescopic device, so that the telescopic device pushes the middle and rear bed plate mechanisms to turn upwards, and the back supporting function is realized.
The process of changing the nursing bed from the state of the bed to the wheelchair state is described as follows: with reference to fig. 12, the tilt assembly is pushed to push the middle and rear bed plate mechanisms to turn upwards, so that the left, middle and right rear bed plate mechanisms turn to a vertical state. The process of forming the wheelchair by the right rear bed board mechanism, the right middle bed board mechanism and the right front bed board mechanism on the right side of the nursing bed is described as follows: as shown in fig. 15 and 16, the right middle bed plate mechanism is turned downwards, and the right rear bed plate mechanism is turned backwards (in this process, the longitudinal telescopic components of the right middle bed plate mechanism and the right rear bed plate mechanism realize the telescopic function, and the rotary component realizes the relative rotation function); the turning assembly between the right middle bed board mechanism and the right front bed board mechanism works to enable the bed board of the right front bed board mechanism to be attached to the bed board of the right middle bed board mechanism, and the armrest assembly at the right front bed board mechanism works to enable hands of a patient to be comfortably placed on the armrest board, as shown in fig. 17 and fig. 18. The process of deforming the left rear bed plate mechanism, the left middle bed plate mechanism and the left front bed plate mechanism on the left side of the nursing bed into a wheelchair is the same as the process of deforming the right rear bed plate mechanism, the right middle bed plate mechanism and the right front bed plate mechanism on the right side of the nursing bed into a wheelchair. And in combination with the illustration of fig. 20, the turning component between the middle bed board mechanism and the middle front bed board mechanism works, so that the middle front bed board mechanism turns downwards, and the whole nursing bed is deformed into a wheelchair.
The following examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the following examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principles of the present invention should be made by equivalent substitution means, and are included in the scope of the present invention.
