Technical Field

The invention relates to a medical transfer trolley.

Background

A medical transfer vehicle is a common instrument used for rescuing patients or wounded persons in daily life. In hospitals, patients often need to change beds among operating tables, CT machines, B-mode ultrasonic examinating tables, hospital beds, etc. due to the need for examination or surgery. The bed position conversion of this kind of patient still relies on medical personnel's manpower transport at present when actual operation, often needs many people to exert force simultaneously and hold up the patient. The transfer trolley and the target bed are relatively wide in distance after being closed, so that the force application of transfer personnel is limited. In addition, the uneven manpower not only makes the transportation laborious, but also has the difficulty in controlling the stability, and is easy to cause severe jolt, so that the patient suffers from secondary trauma. Of course, the present medical transport vehicle with electromechanical equipment is not popularized and applied because of expensive cost of electromechanical equipment or limitation of oil leakage phenomenon of hydraulic equipment to places requiring strict disinfection in hospitals.

Disclosure of Invention

In order to solve the problems, the invention provides the medical transfer trolley which has a simple structure, is simple and convenient to operate and low in manufacturing cost, and can complete the function of translation and bed change among different beds by only one medical worker.

The invention relates to a medical transfer trolley, which is characterized by comprising:

the movable base mechanism comprises an underframe and universal wheels arranged on the underframe and is used for driving the whole transfer trolley to move;

the lifting mechanism is provided with a lifting part and a lifting platform, wherein the bottom of the lifting part is arranged on the underframe of the movable base mechanism, and the lifting platform is arranged at the upper part of the lifting part, so that the lifting platform is driven by the lifting part to vertically lift along the longitudinal direction;

and the transverse shovel type stretcher mechanism comprises a telescopic outer frame and a spliced inner stretcher spliced by two inner stretcher plates, wherein one inner stretcher plate in sliding fit with the lifting platform is respectively fixed on two opposite fixing rods of the telescopic outer frame, and the sliding direction of the inner stretcher plates is kept consistent with the telescopic direction of the telescopic outer stretcher, so that the two inner stretcher plates can move under the driving of the telescopic outer frame.

The telescopic outer frame is composed of two fixing rods and two telescopic rods, wherein the fixing rods and the telescopic rods are alternately connected end to end in sequence to form a closed rectangular structure.

The telescopic link include first telescopic link and second telescopic link, wherein the first end of first telescopic link, the first end of second telescopic link respectively with the dead lever tip rigid coupling of homonymy, the second end of first telescopic link, the second end of second telescopic link pass through the bolt and articulate.

The lifting part comprises a scissor type lifting frame for controlling the height of the lifting platform, a sliding guide rail in sliding connection with a sliding rail on the underframe, a bearing seat and a lifting rocker assembly, the bottom of the scissor type lifting frame is provided with two connecting heads, wherein a first head end of the bottom is hinged on the underframe through the bearing seat, and a second head end of the bottom is in threaded connection with the underframe through the sliding rail; the top of the scissor type lifting frame is also provided with two connecting head ends, a first head end at the top is hinged with the lifting platform through a bearing seat, and a second head end at the top is used as a lifting control end of the scissor type lifting frame and is in locking connection with the underframe through a sliding rail; the lifting rocker assembly is suspended at the bottom of the lifting platform, and the pushing end of the lifting rocker assembly is connected with the second head end at the top of the shear type lifting frame and used for adjusting the longitudinal height of the shear type lifting frame.

The scissor type lifting frame is composed of a plurality of lifting sub-units which are hinged with each other, each lifting sub-unit comprises two lifting support rods, the middle positions of the two lifting support rods are hinged with each other, and the two lifting support rods form a cross-shaped structure with four head ends; the lifting subunits are sequentially arranged from top to bottom, two head ends of the lifting subunit positioned on the lower layer are respectively hinged with two head ends of the adjacent lifting subunits positioned on the upper layer, a first head end at the bottom of the lifting subunit positioned on the bottommost layer is hinged on a bearing seat on the base, and a second head end at the bottom is in threaded connection with the underframe through a sliding rail; the first head end of the top of the uppermost layer lifting subunit is hinged to the lifting platform through a bearing seat, and the second head end of the top is used as a lifting control end of the shear type lifting frame and is in locking connection with the underframe through a sliding rail.

And a locking mechanism is arranged between the lifting platform and the telescopic outer frame and is used for realizing the fixation between the telescopic outer frame and the lifting platform.

The anti-tilt support mechanism is an H-shaped support frame, the upper end of the H-shaped support frame is provided with a mounting hole fixedly connected with a fixing rod of the telescopic outer frame, and the lower end of the H-shaped support frame is provided with a hook used for hooking with the edge of the bottom frame.
