When an operator places the stretcher on the top of the bearing bed plate 2 and releases the support for the stretcher, the electromagnet 12 at the bottom of the transverse plate 302 at the middle position is electrified with forward current, the electromagnet 12 has magnetism and is opposite to the magnetism of the magnetic guide rod 305, the electromagnet 12 drives the magnetic guide rod 305 at the top side to move upwards under the action of magnetic repulsion force, the magnetic guide rod 305 drives the bearing plate 306 at the top to move upwards when moving upwards, the bearing plate 306 drives the stretcher at the top to move upwards when moving upwards, so that the stretcher is in a horizontal stable state under the support action of the clamping grooves 11 in the butt-joint plate 308 and the bearing plate 306, and because the middle part of the bearing plate 306 is made of elastic material, the support force at the bottom of the bearing plate 306 and the extrusion action at the bottom of the body of a patient at the middle part of the bearing plate 306 deform downwards, and further meets the comfort when the lining cloth at the middle part of the stretcher slides at the bottom of the body of the patient, ensuring basic comfort requirements.

And when butt joint plate 308 drives the stretcher and slides at bearing bed board 2 top, because the latter half of stretcher is in unsettled state, consequently can make the stretcher and the patient at its top take place to rotate round the loading board 306 of tip under the dead weight effect of patient and stretcher, and then can cause the secondary injury to the patient, in order to solve above problem, this moment because pressure sensor in the draw-in groove 11 detects its pressure value and is less than first threshold value, the electro-magnet 12 of a set of diaphragm 302 bottom of keeping away from butt joint plate 308 lets in forward current, drive loading board 306 rebound under the effect of the magnetic repulsion of electro-magnet 12 and magnetism guide arm 305 this moment, and then realize the upwards support of loading board 306 to stretcher and patient of tip, guarantee its gliding stability.

When the pressure value detected by the pressure sensor in the slot 11 is further decreased and is smaller than the set minimum threshold, it indicates that the tendency of the stretcher to turn around the end portion bearing plate 306 is increased, the electromagnet 12 at the bottom of the transverse plate 302 near the end of the docking plate 308 is energized with a reverse current, at this time, the electromagnet 12 has a magnetic attraction force on the magnetic guide rod 305 due to the energization of the reverse current, the magnetic guide rod 305 is inserted into the positioning slot 309 downwards, the magnetic guide rod 305 moves downwards to drive the bearing plate 306 to move downwards synchronously, the bearing plate 306 moves downwards to be separated from the stretcher at the top, the wedge-shaped rod 304 moves upwards along the sliding slot 15 relative to the bearing plate 306, the sliding clamp plate 14 stretches the connecting spring 13 to move towards the lifting rod ends at both sides of the stretcher through the wedge-shaped cooperation between the wedge-shaped rod 304 and the sliding clamp plate 14 in the sliding slot 15, and when the magnetic guide rod 305 is inserted into the positioning slot 309, the bearing plate 306 descends to the lowest position, the synchronous relative movement of the sliding clamping plates 14 on the two sides enables the width of the sliding clamping plates to be reduced to the minimum value, the sliding clamping plates 14 descend to the minimum value, the inverted L-shaped structure of the sliding clamping plates 14 is used for clamping the sliding clamping plates 14 with the top of the lifting rods on the two sides of the stretcher and enabling the sliding clamping plates to move downwards, the bearing plate 306 on the top of the transverse plate 302 in the middle position is limited when the bearing plate 306 on the top of the stretcher is turned over, the sliding stability of the stretcher is guaranteed, the electromagnet 12 at the bottom of the transverse plate 302 in the middle position is not electrified, the bearing plate 306 on the top of the transverse plate 302 in the middle position is only connected and fixed through the buffer spring 307, the bearing plate 306 on the top of the stretcher is in contact with the bottom of a patient under the action of the elastic force of the buffer spring 307 at the position at the moment, the wedge-shaped rod 304 is plugged with the chute 15, the comfort and the stability of the patient when the patient slides along with the stretcher are guaranteed, and simultaneously, the bearing plate 306 on one end of the bearing plate 306 far away from one end of the butt plate 308 and the bearing plate 306 on one end close to the butt plate 308 The cooperation has realized the effect that increases the arm of force, and then can apply bigger downward effort to the slope upset of stretcher, improves the protection effect to stretcher stability.

Under the cooperation of the bearing plate 306 close to the end of the abutting plate 308, the stretcher at the top of the bearing bed plate 2 is still in a stable state, the pressure value detected by the pressure sensor in the clamping groove 11 is greater than a set minimum threshold value and smaller than a first threshold value, and the abutting plate 308 is continuously pushed to move towards the end of the positioning plate 16, at this time, because the sliding clamp plate 14 at the top of the bearing plate 306 close to the end of the abutting plate 308 is clamped with the lifting rod of the stretcher at the bottom, the transverse plate 302 can stretch the reset spring 18 to synchronously move along the sliding rail 301 when the stretcher moves, the distance between the sliding clamp plate 14 and the end bearing plate 306 is larger and larger, the force arm is increased, and the bearing force required by the stretcher on the side is smaller and smaller.

When the pressure value detected by the pressure sensor in the slot 11 is greater than the first threshold value, it indicates that the stretcher has been stably placed on the top of the bearing bed plate 2, at this time, the controller controls the electromagnet 12 in the transverse plate 302 at the middle position and the end portion to be powered off, the bearing plate 306 at the middle position and the end portion returns to the original position to be in supporting contact with the stretcher and the bottom of the patient at the top portion under the elastic force of the bottom buffer spring 307, at the same time, the controller controls the electromagnet 12 in the transverse plate 302 at the side close to the abutting plate 308 to be powered off, the bearing plate 306 at the top portion is driven to return to the original position under the elastic force of the buffer spring 307, the wedge-shaped rod 304 moves downward relative to the chute 15 and is out of wedge-shaped fit with the sliding clamp plate 14, and at the same time, the sliding clamp plate 14 is driven to return to the original position under the elastic force of the connecting spring 13, the sliding clamp plate 14 is out of pressing and the lifting rods at both sides of the stretcher, and the transverse plate 302 moves backward to return to the original position under the elastic force of the return spring 18, the stretcher slides on the top of the multiple sets of bearing plates 306, and the bearing plates 306 on the top and the stretcher are elastically supported by the buffer springs 307, so as to ensure the sliding effect.

When the stretcher moves towards the end of the positioning plate 16 along with the abutting plate 308, because the middle of the bearing bed plate 2 is suspended without a supporting effect, the stretcher is only supported by the bearing plate 306 and the abutting plate 308 at the two sides of the bearing bed plate 2, the pressure value detected by the pressure sensor in the slot 11 continuously increases when the stretcher moves, when the pressure value is greater than the set second pressure threshold value, the electromagnet 12 at the bottom of the transverse plate 302 at the middle position is electrified with forward current, the magnetic repulsion of the electromagnet 12 to the magnetic file 305 drives the bearing plate 306 to move upwards and support the bottom of the stretcher, meanwhile, the electromagnet 12 at the bottom of the transverse plate 302 close to one side of the abutting plate 308 is electrified with forward current, further drives the magnetic guide rod 305 and the bearing plate 306 at the top to move upwards and support and protect the bottom of the stretcher, further, the stretcher supports and protects the pressure in the slot 11, and avoids the low sliding efficiency of the abutting plate 308 at the top of the slide rail 301 caused by excessive pressure, hindering its normal sliding.
