Description

A kind of automatic turning mechanism of electric loading stretcher

technical field

The invention relates to the technical field of electric boarding, in particular to an automatic overturning mechanism of an electric boarding stretcher.

Background technique

The interior of modern ambulances is relatively spacious, so that ambulance personnel have enough space to treat patients on the way to the hospital. Modern ambulances also carry a large number of bandages and topical supplies, which can help stop bleeding, clean wounds, and prevent infection.

All ambulances are equipped with stretchers, which are easy to transfer patients. When the traditional ambulance stretcher is used, it is purely mechanized. When the medical staff transfers the patient to the ambulance, the ambulance needs to manually push the stretcher into the ambulance. In the existing technology, in order to reduce the burden of medical staff and provide better rescue for patients, a stretcher structure that can be loaded on the car is now available. However, when such a stretcher on the car is in use, two sets of electric drives are required for the turning and moving of the stretcher. , unable to carry out linkage operation, because the ambulance is used more frequently, it consumes a lot of power, wastes resources, and is not environmentally friendly, and the multi-drive connection method has a high failure rate and delays the treatment of patients. Therefore, we propose an automatic turning mechanism of the electric stretcher.

As a preferred solution of the automatic turning mechanism of the electric loading stretcher according to the present invention, the second rotating shaft is located between the first mounting frame and the second mounting frame, and is away from one end of the first rotating shaft.

Compared with the prior art, the present invention has the beneficial effects as follows: through the mutual cooperation of the set upturning mounting frame structure and the turning structure, the stretcher movement and the stretcher turning are linked together, and the stretcher can be turned and displaced by a single motor operation. At the same time, when the stretcher returns, it will automatically level and return to reduce energy use, which is more environmentally friendly, reduces the failure rate of multiple motors, and is easy to use. Drive the connecting sleeve to move forward, thereby driving the first rotating shaft and the stretcher support plate to move forward. During the moving process, the second rotating shaft rolls on the bottom surface of the stretcher support plate, which reduces friction and improves the stretcher support plate during displacement. Smooth, in the process of forward displacement of the stretcher support, the second rotating shaft acts as a fulcrum, the first rotating shaft moves forward, and the stretcher support plate is misaligned with the first installation frame and the second installation frame. At this time, the overhanging weight is greater than the center of gravity, One end of the stretcher support plate is inclined downward to form an inclination angle until one end of the stretcher support plate is in contact with the ground. When the stretcher support plate is recovered, the driving motor drives the walking screw body to move in the opposite direction. , the stretcher support plate is gradually flush with the first installation frame, until the stretcher support plate is completely flat and returned.
