Improvement as such scheme, described trident rocking arm comprise two respectively with two groups of described fixing support racks or two groups of lower links that described assistant support is connected, a middle link hinged with described bed frame, and a upper link hinged with described electric pushrod shell end.
As the improvement of such scheme, described lower bedstead comprises underframe and is located at the pulley of four jiaos, described underframe.
As the improvement of such scheme, before and after described underframe one end, be provided with symmetrically two groups of fixing support racks, before and after the other end, be provided with symmetrically two groups of assistant supports.
As the improvement of such scheme, described trident rocking arm can overturn take the hinged place with described fixing support rack or described assistant support as rotating shaft up or down under the push-and-pull action of described electric pushrod.
As the improvement of such scheme, described electric pushrod is provided with encoder.
Implement this utility model, have following beneficial effect:
This utility model uses the mode of electric pushrod driving trident rocking arm by the lifting of bed body and decline, can stably control medical bedstead and rise and descend, compact conformation; And the driving element such as electric pushrod all has sealing, has stronger capacity of resisting disturbance, can adapt to severe working environment.
This utility model electric pushrod is provided with encoder, can accurately control according to the electric machine frequency in electric pushrod the stroke of electric pushrod, thereby guarantees medical bedstead steadily level rising or decline.
This utility model is left the bed and has been set up pulley, can to patient, carry out easily the transfer of each section office.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is described in further detail.
as shown in Figures 1 to 4, a kind of lifting hospital bed, comprise bed frame 1, lower bedstead 2 and be located at described bed frame 1 and lower bedstead 2 between lowering or hoisting gear 3, described lowering or hoisting gear 3 comprises bracing frame 4, trident Rocker arm 5 and electric pushrod 6, support frame as described above 4 comprises the head of a bed that is fixed at described lower bedstead 2 or the tailstock wherein fixing support rack 41 of an end and the assistant support 42 of the other end, the top of described fixing support rack 41 and described assistant support 42 is hinged with described trident Rocker arm 5 separately, all the other two ends of described trident Rocker arm 5 are hinged with shell end and the described bed frame 1 of described electric pushrod 6 respectively, the bottom central part of described bed frame 1 is divided and is fixed with hinged seat 7, the push rod 8 of described electric pushrod 6 is hinged with described hinged seat 7.
It should be noted that, operation principle of the present utility model is, when described lifting hospital bed need to the rising, described electric pushrod 6 is started working, and described push rod 8 is protruding, under the combined effect of two secondary electric pushrods 6, described trident Rocker arm 5 is upset upwards, drives described bed frame 1 vertical lifting; When described lifting hospital bed need to decline, described electric pushrod 6 is started working, and described push rod inwardly shrinks, and under the combined effect of two secondary electric pushrods 6, described trident Rocker arm 5 overturns downwards, drives described bed frame 1 and vertically descends.
