certainly, the two ends of the second electric push rod 11 and the connection position thereof are also provided with a connecting piece, such as a pin, the second electric push rod 11 can move along the connecting piece, so that the purpose of not obstructing the movement of the second electric push rod 11 is achieved, and the connection structure can refer to the connection of the first electric push rod 4;

as another preferred embodiment, the rotating joint 10 is used between the first branch plate 81 and the second branch plate 82 instead of the hinge 9, and the second branch plate 82 and the third branch plate 83 are connected by the hinge 9, so that the rotating joint 10 has better rotating performance compared with the hinge 9, the bearing capacity of the rotating joint 10 is stronger, and the service life of the rotating joint 10 is longer if the first branch plate 81 is lifted frequently;

the angle position of the first branch plate 81 is adjusted, so that the back of a user can comfortably lean against the first branch plate 81, and the user can sit up to have a rest, eat and read a book conveniently;

as a preferred embodiment, the bed board can be made of a compact board;

divide board 81 can adopt extruded profile and conbert board to constitute, and this kind of material comfort level is high, and user's back leans on and experiences the effect well on dividing board 81.

In order to reduce the weight of the whole structure, the bed plate 8 is provided with hollowed holes 12 at intervals, and the hollowed design can not only reduce the whole weight of the nursing bed, but also can not influence the bearing and the flatness of the bed plate;

as a preferred embodiment, one end or two ends of the support frame 1 in the length direction are provided with a bedside baffle 13; and/or bed periphery is arranged at one end or two ends of the width direction of the support frame, and the bedside baffle 13 can prevent the nursing bed from dropping off the bed. The bed board 8 can also be made of magnesium alloy materials, and can also be made of plastics and other materials;

the bedside baffle 13 and the support frame 1 can be connected by a fixing piece, such as a bolt, so that the aim of conveniently disassembling the bedside baffle 13 can be fulfilled;

in the invention, the first electric push rod 4 and the second electric push rod 11 are controlled to be started by a controller, the controller can be arranged at any position above the support frame 1 or the baffle 13, which is convenient for a user to use, or the controller can be arranged in the shape of a remote controller, and the user can hold the controller in the hand to adjust the position; the controller can control the first electric push rod 4 and the second electric push rod 11 at the same time, and can also control the start of each electric push rod independently, and the prior art has the prior art of controlling one or more electric push rods simultaneously and independently, so detailed descriptions on how to control the electric push rods and the controller are not repeated here.

When the controller can independently control each electric push rod, the heights of the support frames 1, which are adjusted by the first electric push rods 4 at two sides, from the ground can be different, so that the state that one side is high and the other side is low is realized, namely a slope is formed between the support frame 1 and the ground; is convenient for some patients to need.

As a preferred embodiment, the bottom end of the first rod part 2 is connected with a roller, the arrangement of the roller is convenient for pushing the device, and further preferably, the roller can be folded, that is, the roller can be stored when not in use, and the folding and storing technology of the roller can use the existing scheme. Or the roller is provided with a stop structure, so that the position of the roller can be locked under the condition that the nursing bed does not need to be moved;

the invention is convenient for users to use, can use little strength when moving patients with inconvenient actions, and the device can be completely laid flat, is convenient to store and saves space.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention shall be included in the scope of the present invention.
