Specific embodiment
Below this utility model is described in detail:
1. the selection of elevating mechanism
There are many kinds, such as screw-nut body, linkage, cam mechanism etc. in the mechanism of achievable lifting action.Make For the armarium that patient uses, especially critically ill patient, the kinetic characteristic of mechanism must be steady, can not have larger inertia to add Speed, the preferably only movement of vertical direction.Screw-nut body can meet this requirement, but adopt screw-nut body spiral shell Bar can occupy larger space, and screw rod projects bed body, affect attractive in appearance.Quadric chain and toggle, kinesiology Characteristic is poor, and stroke is shorter, and there are quickreturn characteristics rock can patient body for which, unfavorable to the body of patient.Then, this practicality It is new to propose a kind of motor-driven scissors-type lifting.
Scissor mechanism is a kind of mechanism with single degree of freedom, scissor mechanism under identical lifting altitude, with less longitudinal direction Size and storage height, larger dimensional variations amplitude, and larger displacement equations rate;Concrete structure is as follows:
Scissors-type lifting includes driving performs device and scissor device.Under the driving of drive mechanism, driving performs dress Scissor device is transmitted drive force to while putting generation thin tail sheep stroke.Scissor device has as the main body of scissors-type lifting There is the performance of folding extension, it is driven the driving of performs device and zooms into the thin tail sheep stroke for driving performs device perpendicular Nogata to larger stroke, so as to promote moving up and down for hoistable platform.
Therefore in this utility model, elevating mechanism adopts scissors-type lifting, drives by motor 3, by shaft coupling 4 drive leading screws 14 rotate, and the displacement constraint of fixed leading screw 14 is fixed on pair of nut on bearing pin, will by screw-nut body The rotary motion of motor is transformed into linear motion, so as to drive the link rotatable of scissor mechanism, and then drives scissor mechanism, realizes The rising of bed board, descending motion.
2. the selection of translation mechanism
Need to consider to allow bed board smoothly to move to other sick beds or handss from present sick bed when displacement mechanism is selected Art platform, pinion and rack can be very good to meet this use requirement.Motor continuously runs, as long as rack rails is of convenient length, Sick bed can be made to move to optional position.
To meet the stability of strutting system of bed board, several pieces of gripper shoes and guide rail are welded under bed board, motor and gear are fixed on On elevating mechanism, guide rail is fixed on bed board, motor 8 is rotated with moving gear, so as to drive rack rails and bed board motion.
