Example 2
As shown in fig. 4 to 7, in the embodiment 1, the self-locking mechanism 6 includes a spur gear 601, a bearing rod 602 is fixedly connected to the upper surface of the spur gear 601, the surface of the bearing rod 602 is rotatably connected to the inside of the moving plate 8, a first bevel gear 603 is fixedly connected to the top end of the bearing rod 602, a second bevel gear 604 is meshed with the surface of the first bevel gear 603, and a threaded rod 605 is fixedly connected to the axial center of the second bevel gear 604.
The first bevel gear 603 and the second bevel gear 604 have larger load, high centering accuracy requirement and very high technical requirement, and are inevitably subjected to huge friction force in the working process, and the best method is to perform quenching heat treatment on the bevel gears, so that the hardness, the wear resistance and the service life of the bevel gears can be improved.
In this embodiment, the surface thread of the threaded rod 605 is connected with a supporting block 606, the rear part of the supporting block 606 is fixedly connected with a first connecting block 607, the inside of the first connecting block 607 is rotationally connected with a third connecting bar 608 through a rotating shaft, the inside of the third connecting bar 608 is rotationally connected with a second connecting block 609 through the rotating shaft, the rear part of the second connecting block 609 is fixedly connected with a sliding plate 610, the left side of the sliding plate 610 is in sliding connection with the right side of the second fixed baffle 9, and the lower surface of the sliding plate 610 is in contact with the upper surface of the moving plate 8.
The sliding plate 610 can be close to the third fixed baffle 10 by arranging the threaded rod 605 to rotate, the third fixed baffle 10 and the sliding plate 610 clamp the wheels of the transfer trolley, and the transfer bed is self-locked, so that the transfer bed can not shake back and forth due to the pain of a patient, and medical staff can not treat the patient well.
Further, the turnover mechanism 7 includes a pedal 701, the lower surface of the pedal 701 contacts with the upper surface of the moving plate 8, the lower surface of the pedal 701 is fixedly connected with a first fixing strip 702, the lower surface of the first fixing strip 702 is fixedly connected with a rotating rod 703, and two ends of the rotating rod 703 are both rotatably connected with the inner part of the moving plate 8.
Through setting up tilting mechanism 7 when movable plate 8 and ground contact, footboard 701 can rotate ninety degrees and ground contact, and the transfer car (buggy) just need not medical personnel manually lift up on movable plate 8 at this moment, only need hand propelled on movable plate 8, and resistance also can become less at the in-process of promotion, has alleviateed medical personnel's physical power.
The surface fixedly connected with second fixed strip 704 of dwang 703, the left side fixedly connected with sliding strip 705 of second fixed strip 704, sliding strip 705's surface and the inside sliding connection of movable plate 8, sliding strip 705's upper surface fixedly connected with second spring 706, the top and the inside fixed connection of movable plate 8 of second spring 706.
Through setting up second spring 706, at the in-process that movable plate 8 risees, slider 705 can leave ground, and at this moment under the effort of second spring 706, footboard 701 can anticlockwise rotate ninety degrees and the upper surface contact of base 1, just so guaranteed that the condition that the transfer car (buggy) can not appear swift current car in the in-process of going up and down, ensured patient's security.
The theory of operation, when movable plate 8 is wanting to contact the ground, the pressure that the movable plate 8 and ground made the slider 705 slide into the inside of movable plate 8, can drive second fixed strip 704 upwards when slider 705 slides, and second fixed strip 704 can drive dwang 703 rotatory, and dwang 703 rotatory can drive first fixed strip 702 rotatory, and first fixed strip 702 can drive footboard 701 rotatory, makes footboard 701 and ground contact, and the resistance that moves movable plate 8 at the transfer car (buggy) will become less, makes the easier push to movable plate 8 of transfer car (buggy) above.
When the transfer trolley pushes up the moving plate 8, the output end of the air cylinder 403 stretches to drive the first connecting strip 404 and the second connecting strip 405 to rotate clockwise, the first connecting strip 404 and the second connecting strip 405 drive the second supporting frame 406 to lift up and move leftwards, when the moving plate 8 lifts up and leaves the ground, the sliding strip 705 leaves the moving plate 8 through the action force of the second spring 706 without pressure of the ground, the sliding strip 705 drives the second fixing strip 704 to move downwards, the second fixing strip 704 drives the rotating rod 703 to rotate, the rotating rod 703 rotates to drive the first fixing strip 702 to rotate, the first fixing strip 702 drives the pedal 701 to rotate, the pedal 701 contacts with the upper surface of the moving plate 8, the situation that the transfer trolley slides in the lifting process is solved, and the safety of a patient is ensured.
When the movable plate 8 contacts with the base 1, the spur gear 601 is meshed with the rack 3, the movable plate 8 moves to the left side of the base 1 by manually pushing the transfer trolley, the spur gear 601 is driven to rotate by the rack 3 in the moving process, the bearing rod 602 is driven to rotate by the spur gear 601, the first bevel gear 603 is driven to rotate by the bearing rod 602, the second bevel gear 604 is driven to rotate by the first bevel gear 603, the threaded rod 605 is driven to rotate by the second bevel gear 604, the supporting block 606 is driven to move rightward by the threaded rod 605, the third connecting bar 608 is driven to expand by the supporting block 606 through the first connecting block 607, and the sliding plate 610 is close to the third fixed baffle 10 through the second connecting block 609.
The wheels of the transfer trolley are clamped between the third fixed baffle 10 and the sliding plate 610, the condition that the transfer trolley does not shake on the moving plate 8 is guaranteed, the condition that medical staff cannot treat patients due to shaking of the transfer bed is avoided, because the moving plate 8 can downwards press the lifting block 502 when being in contact with the base 1, when the moving plate 8 is in contact with the first fixed baffle 2, the lower surface of the moving plate 8 can leave the upper surface of the lifting block 502, the lifting block 502 can be lifted under the acting force of the first spring 505, the moving plate 8 is clamped between the first fixed baffle 2 and the lifting block 502, the condition that the moving plate 8 shakes in the running process of the ambulance is avoided, the condition that the patient is uncomfortable is caused, and when the transfer trolley needs to go down the ambulance, the moving plate 8 can be pushed out only by downwards pressing the pressing plate 501.
