Has the advantages that:
the invention has simple use, convenient transfer, time and labor saving, greatly lightens the burden of medical staff, has high speed, more importantly saves precious time for rescuing patients and has good use effect. When the lifting machine works, the screw rod rotates to drive the screw rod to lift, the screw rod nut drives the bottom plate to lift, the guide rod slides in the guide hole to play a role in guiding, the whole bed body is ensured to be stable and stable in the lifting process, the bed body is ensured to be uniformly stressed and cannot be inclined or toppled over, in work, the motor rotates to drive the first connecting rod to rotate, the first connecting rod rotates to drive the second connecting rod to rotate, the second connecting rod drives the connecting plate to rotate around the right boss of the side plate, so that the left bed plate can be kept in a horizontal state in space, and the left and right reciprocating movement is realized under the driving of the motor.
The stop plate is connected with the lower end pillow block through the one-way bearing, the stop plate is positioned between the stop plate frame and the nut through the nut on the shaft, when the cam rotates, the stop plate can be driven to rotate under the driving of the one-way bearing, when the handle is pulled, the sliding block can slide downwards in the sliding groove and loosen the handle, the sliding block can return to the upper part of the sliding block under the action of a large spring, the sliding groove and the sliding block are of a rectangular structure, the guide effect is achieved, the sliding block is prevented from rotating, the positioning accuracy is influenced, the positioning pin is blocked or falls off, the right bed plate cannot be positioned, danger is brought to a patient, the pin spring and the positioning pin are simultaneously placed in the positioning pin hole, the right side of the pin spring props against the bottom of the positioning pin hole, the left side of the positioning pin is propped against the right side of the positioning pin, the positioning pin is positioned on the left side of the positioning pin hole under the action of the pin spring, and the pin head is ensured to be positioned on a vertical groove, an upper end hole, a lower end hole, a first spiral groove and a first spiral groove all the time, The bottom of the second spiral groove prevents the positioning pin from falling off to cause that the right bed board can not be positioned and bring danger to patients, the anti-falling pin penetrates through the positioning pin to slide in the kidney-shaped hole to prevent the positioning pin from rotating to damage a pin spring and cause the clamping or falling off of the positioning pin to cause that the right bed board can not be positioned and bring danger to patients, in an initial state, the pin head is positioned in the upper end resident hole, at the moment, the large spring props against the sliding block, the pin spring props against the positioning pin, the pin head is tightly attached to the upper end resident hole to ensure that the pin head can not fall off the upper end resident hole, when the handle is pulled, the pin head moves downwards under the driving of the sliding block, as the depth of the vertical groove is shallow, a step is generated, the pin head can not move downwards along the vertical groove, at the moment, the pin head can generate a rotating moment to the side surface of the second spiral groove or the first spiral groove, the cam can rotate, and the bottom of the upper end resident hole and the second spiral groove are positioned on a plane, the pin head slides along the second spiral groove or the first spiral groove, when the handle is pulled to the lower end hole, the cam just rotates, the handle is loosened, the sliding block moves upwards under the driving of the large spring, because the depth of the lower end hole is consistent with the depth of the ending part of the second spiral groove and the first spiral groove, the sliding block drives the pin head to move upwards along the vertical groove until reaching the upper end resident hole, because the depth of the upper end resident hole is deeper, the pin head is positioned at the upper end resident hole under the action of the pin spring, the handle is pulled again, the cam rotates again, when the first spiral groove or the second spiral groove is a left spiral, the cam rotates clockwise, when the first spiral groove or the second spiral groove is a right spiral, the cam rotates clockwise, the one-way bearing ensures that the cam can drive the stop plate to rotate together when rotating, otherwise, the stop plate drives the cam to rotate reversely when rotating reversely, when the stop plate is positioned below the right bed board, the right bed board can be supported, so that the stop plate is positioned in a horizontal position, and when the stop plate rotates to the outer side of the right bed board, the right bed board loses the support and is in a movable state.
Because the rack is fixed on the outer side of the side plate, the stop plate frame is fixed on the left bed board, when the left bed board returns to the initial state from the front end and the stop plate is positioned on the outer side of the right bed board, the right bed board is not supported, so that the safety risk exists, the outer side of the half gear is just opposite, in order to ensure that the stop plate rotates to the lower part of the right bed board to support the right bed board, the left bed board can slowly descend and retract in the retracting process, the half gear is contacted with the half gear to start meshing, the half gear drives the stop plate to rotate, the stop plate is separated from the contact when rotating by 180 degrees, the stop plate is positioned below the right bed board at the moment and just supports the right bed board, if the left bed board returns to the initial state from the front end and the stop plate is positioned below the right bed board, the back of the half gear faces upwards, no gear exists, the stop plate can not rotate at the moment, so that when the left bed board retracts, if the stop plate is not positioned below the right bed board, the stop plate is forced to rotate below the right bed board to support the right bed board, so that the safety of a patient is guaranteed, when the connecting plate extends forwards, the back of the half gear always faces to the back of the half gear, and the stop plate cannot generate any action to guarantee the safety.
