[0016] Beneficial effects compared with the prior art:

[0017] 1. In this solution, when the patient needs to turn over, the servo motor is started, the moving plate moves and contacts with the L-shaped push plate, at which time the moving plate will move against the lower end of the L-shaped push plate, and the lower end of the L-shaped push plate will be pushed by the moving plate, and the bending part of the L-shaped push plate is connected to the connecting short shaft, at which time the upper end of the L-shaped push plate will tilt up with the movement of the moving plate, because the L-shaped push plate at the front end is connected to the L-shaped push plate at the rear end by the connecting long plate, so the upper end of the L-shaped push plate at the rear side will also tilt up, and the tilting of the two L-shaped push plates will drive the corresponding bed boards to fold, and the folded bed boards will help patients lying on the radiology nursing bed to turn over, thereby improving the convenience of patients turning over, avoiding manual assistance of medical staff to turn over patients, and reducing the work intensity and operation difficulty of medical staff;

[0018] 2. In this solution, the rotation of the two screw rods 1 will drive the moving block to move. Since the two limit sliders 1 are both located in the two limit slide grooves 1, the moving block can only move along the track of the limit slide groove 1, making the moving block more stable during the movement;

[0019] 3. In this solution, when the folding mechanism is not used, four L-shaped clamps will clamp and fix the two bed boards on the supporting long board, avoiding the problem of accidental folding of the radiology nursing bed due to external force collision or other factors when moving, and increasing the safety of patients when using it;

[0020] 4. In this solution, when the lifting long board descends to the end of the rifle pole, it will abut against the abutment plate, thus avoiding the problem of the fence falling off due to excessive descent of the lifting long board;

[0021] 5. In this solution, when the two extension plates move away from each other, the four springs will be stretched. Since the connecting tube is connected to the connecting short plate, the connecting column 1 will be separated from the connecting tube along with the extension plate. When the limiting slider 2 abuts against the edge of the limiting slide groove 2, the extension plate stops moving, thus avoiding the risk of the extension plate being separated due to excessive movement of the extension plate.

[0022] 6. In this solution, when the two extension plates extend outward, they will drive the corresponding rotating gears to move. Since the rotating gears are meshed with the racks, the rotating gears will rotate while moving, and the rotating gears will drive the corresponding rifle rods to rotate. When the rifle rods rotate, they will drive the corresponding lifting long boards and fences to rise from the second long slot, so that the fences can assist the patients when they turn over, reducing the risk of the patients falling from the radiology nursing bed due to excessive turning. When the two extension plates are reset, the two rifle rods will also rotate in the opposite direction to drive the fences and lifting long boards to descend. At this time, the fences are located at the lower end of the radiology nursing bed, avoiding the problem that the fences will block part of the patient's body when the patient is undergoing CT, MRI and other scanning examinations, so that the scanning equipment will not be affected when examining the patient.

The tilting of the two L-shaped push plates 15 will drive the corresponding bed boards 12 to be folded. The folded bed boards 12 will help patients lying on the radiology nursing bed to turn over, thereby improving the convenience of patients turning over.

[0039] Two connecting plates 18 are provided at the lower end of the supporting long plate 14, and the front end side of each connecting plate 18 is fixedly connected to two L-shaped supporting plates 19, and the upper ends of the four L-shaped supporting plates 19 are fixedly connected to the lower end of the supporting long plate 14, and the front ends of the two connecting plates 18 are provided with screw rods 26, and the two ends of each screw rod 26 are fixedly connected to two rotating short columns 25, and the four rotating short columns 25 are rotatably connected to the four L-shaped supporting plates 19, and the opposite ends of the two rotating short columns 25 located in the middle are A meshing bevel gear 34 is fixedly connected, and a connecting short column 50 is arranged between the two meshing bevel gears 34. One end of the connecting short column 50 is fixedly connected to a rotating bevel gear 33. Both ends of the rotating bevel gear 33 are meshed and connected with the two meshing bevel gears 34. When the connecting short column 50 rotates, the rotating bevel gear 33 is driven to rotate, and the rotating bevel gear 33 is driven to rotate the two meshing bevel gears 34.

The two limiting sliders 27 are slidably connected to the corresponding connecting plate 18 through the limiting slide groove 29, and the rotation of the two screw rods 26 will drive the moving block 28 to move. Since the two limiting sliders 27 are both located in the two limiting slide grooves 29, the moving block 28 can only move along the trajectory of the limiting slide groove 29, so that the moving block 28 is more stable during the movement.

Two card slots 20 are provided at the side end of each bed board 12. The card slot 20 is adapted to the upper end of the L-shaped card block 21. The upper end of each L-shaped card block 21 is connected to the corresponding bed board 12 through the card slot 20. When not in use When the folding mechanism is used, the four L-shaped blocks 21 will clamp and fix the two bed boards 12 on the supporting long board 14, avoiding the problem of accidental folding of the radiology nursing bed due to external force collision or other factors when moving, and increasing the safety of patients when using it.

The rotation of the second connecting short column 53 will drive the elliptical push plate 52 to rotate, and the rotation of the elliptical push plate 52 will push the two extension plates 40 to extend in opposite directions. When the two extension plates 40 move, they will drive the corresponding L-shaped card blocks 21 to move. At this time, the L-shaped card blocks 21 will cancel the card connection with the two bed boards 12, so that there will be no movement interference in the subsequent folding process of the bed board 12. The lower end of the second connecting short column 53 A meshing bevel gear 2 54 is fixedly connected, and a rotating bevel gear 2 51 is vertically meshed at the side end of the meshing bevel gear 2 54.

When the two extension plates 40 move away from each other, the four springs 55 will be stretched. Since the connecting tube 56 is connected to the connecting short plate 43, the connecting column 1 59 will continuously separate from the connecting tube 56 as the extension plate 40 is extended. When the limiting slider 2 57 abuts against the edge of the limiting slide groove 2 58, the extension plate 40 stops moving, avoiding the risk of the extension plate 40 being separated due to excessive movement of the extension plate 40. When the servo motor 17 is controlled to output in the reverse direction, the elliptical push plate 52 returns to the initial state. At this time, the four springs 55 will pull the corresponding extension plate 40 back to its original position.

The lower ends of the two fences 47 are fixedly connected to a lifting long plate 48, and both ends of the lifting long plate 48 are threadedly sleeved with the corresponding rifle rod 61. When the two extension plates 40 extend outward, the corresponding rotating gear 45 will be driven to move. Since the rotating gear 45 is meshed with the rack 46, the rotating gear 45 will When the two extension plates 40 are reset, the two rifle rods 61 will also rotate in the opposite direction to drive the fence 47 and the lifting board 48 to descend.

If the patient needs to turn over to the left, the bed board 12 on the left side needs to be folded at this time, and the staff The nut 37 on the right side is screwed so that the movable plate 32 on the right side is disassembled. At this time, the movable block 28 on the left side will drive the corresponding movable plate 32 to move. The movable plate 32 moves and contacts with the L-shaped push plate 15. At this time, the movable plate 32 will resist the lower end of the L-shaped push plate 15 to move, and the lower end of the L-shaped push plate 15 will be pushed by the movable plate 32. The bending part of the L-shaped push plate 15 is connected to the connecting short shaft 23. At this time, the upper end of the L-shaped push plate 15 will tilt up with the movement of the movable plate 32. Since the L-shaped push plate 15 at the front end is connected to the L-shaped push plate 15 at the rear end by the connecting long plate 24, the upper end of the L-shaped push plate 15 at the rear side will also tilt up. The tilting of the two L-shaped push plates 15 will drive the corresponding bed board 12 to fold. The folded bed board 12 will help the patient lying on the radiology nursing bed to turn over, and the movable plate 32 at the right end is disassembled, so the bed board 12 at the right end will not be folded.

[0046] In the second step, there is a gap between the moving plate 32 and the L-shaped push plate 15. When the moving plate 32 moves toward the L-shaped push plate 15, the connecting short column 1 50 rotates, which drives the transmission column 42 to rotate through the damping shaft 30. The transmission column 42 drives the rotating bevel gear 2 51 to rotate. The rotating bevel gear 2 51 drives the meshing bevel gear 2 54 and the connecting short column 2 53 to rotate. The rotation of the connecting short column 2 53 drives the elliptical push plate 52 to rotate. The rotation of the elliptical push plate 52 pushes the two extension plates 40 to extend in opposite directions. When the two extension plates 40 move, they drive the corresponding L-shaped clamping blocks 21 to move. At this time, the L-shaped clamping blocks 21 cancel the clamping of the two bed boards 12, so that there will be no movement interference in the subsequent folding process of the bed boards 12.

[0047] In the third step, when the two extension plates 40 extend outward, they will drive the corresponding rotating gear 45 to move. Since the rotating gear 45 is meshed with the rack 46, the rotating gear 45 will rotate while moving. The rotating gear 45 will drive the corresponding rifle rod 61 to rotate. When the rifle rod 61 rotates, it will drive the corresponding lifting long plate 48 and fence 47 to rise from the long groove 49, so that the fence 47 will assist the patient when turning over, reducing the risk of the patient falling from the radiology nursing bed due to excessive turning.

[0048] In the fourth step, when the two extension plates 40 move away from each other, the four springs 55 will be stretched. Since the connecting tube 56 is connected to the connecting short plate 43, the connecting column 1 59 will continue to detach from the connecting tube 56 along with the extension plate 40. When the limiting slider 2 57 presses against the edge of the limiting slide groove 2 58, the extension plate 40 stops moving. When the extension plate 40 stops extending, the transmission column 42 and the inner ring of the damping shaft 30 will interfere with each other and cannot continue to rotate, while the connecting short column 1 50 and the outer ring of the damping shaft 30 will not be affected and can continue to rotate with the output of the servo motor 17. At this time, the movable plate 32 continues to move until it pushes the L-shaped push plate 15, ensuring the continuity of the bed board 12 during the folding process.

[0049] In the fifth step, after the patient turns over on the radiology nursing bed, the servo motor 17 is controlled to output in the reverse direction, and the moving block 28 controls the moving plate 32 to reset. At this time, the moving plate 32 no longer resists the L-shaped push plate 15. At this time, the bed board 12 will gradually flatten, and the elliptical push plate 52 will return to its initial state. At this time, the four springs 55 will pull the corresponding extension plates 40 back to their original positions. When the two extension plates 40 are reset, the two rifle rods 61 will also rotate in the opposite direction to drive the fence 47 and the lifting long board 48 to descend. At this time, the fence 47 is located at the lower end of the radiology nursing bed, which avoids the problem that the fence 47 will block part of the patient's body when the patient is undergoing CT, MRI and other scanning examinations.

[0050] In the sixth step, when the lifting plate 48 descends to the end of the rifle rod 61, it will abut against the abutment plate 62, thereby avoiding the problem of the fence 47 falling off due to excessive descent of the lifting plate 48.

[0051] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
