The rotation of the fourth gear 26 drives the fourth rack 261 to move. The fourth rack 261 and the second rack 241 move together to drive the protection rod 245 to move upward. While moving, the protection rod 245 is extended to protect the patient on the bed board 16 to prevent the patient on the bed board 16 from falling off the bed board 16 during the transfer process, causing unnecessary damage to the patient.

[0023] At the same time, when the patient lies on the bed board 16, the patient's injured leg is placed on the lifting plate 313. During the rising process of the bed board 16, the fourth gear 26 rotates to drive the fifth gear 33 to rotate, and the fifth gear 33 rotates to drive the rotating roller 31 to rotate. The rotation of the rotating roller 31 drives the traction rope 311 to tighten, and the lifting plate 313 on the bed board 16 is slowly lifted. During the lifting process, the patient's injured part is lifted at the same time to protect the injured part to prevent secondary injury during the movement. At the same time, when the patient's leg is lifted to the predetermined position, the limit rod 263 and the limit hole 35 are just plugged in. After the plugging is completed, the staff will pull out the moving sleeve 34 to drive the fifth gear 33 to disengage from the fourth gear 26 to ensure that the patient's legs will not fall due to gravity after being lifted to a certain extent.

[0024] In an optional embodiment, limiting blocks 161 are provided at both ends of the bed board 16 , and limiting grooves 15 are provided on the limiting plate 13 , and the size of the limiting grooves 15 is adapted to the limiting blocks 161 .

[0030] In an optional embodiment, a first hole is provided on the baffle 12 , and the size of the first hole is adapted to the movable sleeve 34 .

[0031] It should be noted that when the patient's legs are raised to a certain extent, the medical staff pulls out the movable sleeve 34 inside the first hole, driving the fifth gear 33 to move, so that the fifth gear 33 and the fourth gear 26 are disengaged and no longer meshed, to prevent the patient's legs from continuing to rise and causing damage to the patient. At the same time, when the patient needs to be transferred, the medical staff manually reinserts the movable sleeve 34 to make the fourth gear 26 and the fifth gear 33 mesh again, and cooperates with the descent of the bed board 16 to make the patient's legs slowly descend. When it drops to the lowest point, the lifting plate 313 contacts the bed board 16, making it convenient for the medical staff to move the patient's legs out.

[0032] In an optional embodiment, the fifth gear 33 is meshed with the fourth gear 26 , and the fifth gear 33 is slidably connected to the rotating roller 31 .

[0033] It should be noted that the rotation of the fourth gear 26 drives the fifth gear 33 to rotate. At the same time, the fifth gear 33 is slidingly connected to the rotating roller 31. The fifth gear 33 can be moved on the rotating roller 31 by pushing the movable sleeve 34, which makes it convenient for medical staff to control the meshing relationship between the bed board 16 and the fifth gear 33, and to conveniently control the lifting distance of the patient's legs.

[0034] In an optional embodiment, one end of the traction rope 311 is fixedly connected to the rotating roller 31 , the lifting plate 313 is arranged on the upper end of the bed board 16 , and the other end of the traction rope 311 passes around the positioning rod 314 and the traction column 312 to be connected to the lifting plate 313 .

[0035] It should be noted that the rotation of the rotating roller 31 drives the traction rope 311 to be wound around the rotating roller 31, so that the lifting plate 313 moves along with the rotation of the rotating roller 31, which is convenient for adjusting the height of the patient's legs, protecting the patient's legs, and avoiding secondary damage to the injured part of the patient during transportation.

[0036] In an optional embodiment, a groove is provided at the upper end of the baffle 12, and the protection rod 245 reciprocates in the groove.

[0037] It should be noted that a groove is provided at the upper end of the baffle 12, which facilitates the protection rod 245 to be retracted into the inside of the baffle 12 when it is lowered, so as to facilitate medical staff to transfer the patient on the bed board 16. At the same time, the protection rod 245 is extended when the bed board 16 is raised, so as to protect the patient during the transfer process and prevent the patient from falling off the bed board 16 during transfer and causing injury.

[0038] In an optional embodiment, a storage box 17 is fixedly provided on the upper end of the base 1 .

[0039] It should be noted that, during transportation, the patient's personal belongings and some commonly used medicines can be placed in the storage box 17 to facilitate the patient's use and improve the practicality of the device.

[0040] In an optional embodiment, the gasket 22 is made of elastic material.

[0041] It should be noted that the gasket 22 is made of elastic material and cushions the bed board 16 when the electric push rod 21 pushes the bed board 16 to rise.

[0042] Working principle: Before starting to use the device, lower the device to the lowest position to facilitate medical staff or accompanying personnel to transfer the patient to the bed board 16. After the patient is transferred to the bed board 16, the electric push rod 21 pushes the gasket 22 to move, and the movement of the gasket 22 drives the bed board 16 to move upward, driving the patient on the bed board 16 to move upward, so as to facilitate the transportation of the patient on the bed board 16 after the subsequent transfer is completed, and avoid excessive workload of the transport personnel caused by too long a transportation journey.

[0043] At the same time, during the rising process of the bed board 16, it drives the first through rods 242 on both sides to move, and drives the first gear 23 on the first through rod 242 to move upward. The first gear 23 moves upward and contacts with the first rack 231, so that the first gear 23 rotates while moving upward. The rotation of the first gear 23 drives the second gear 24 to rotate. The rotation of the second gear 24 drives the second rack 241 to move. At the same time, the movement of the bed board 16 drives the third gear 25 to move. The third gear 25 moves and contacts with the third rack 251, so that the third gear 25 rotates while moving upward. The rotation of the third gear 25 drives the fourth gear 26 to rotate. The rotation of the fourth gear 26 drives the fourth rack 261 to move. The fourth rack 261 and the second rack 241 move together to drive the protection rod 245 to move upward. While moving, the protection rod 245 is extended to protect the patient on the bed board 16, and it is convenient for medical staff to push.

[0044] At the same time, when the patient lies on the bed board 16, the patient's injured leg is placed on the lifting plate 313. During the rising process of the bed board 16, the fourth gear 26 rotates to drive the fifth gear 33 to rotate, and the fifth gear 33 rotates to drive the rotating roller 31 to rotate.

The first gear 23 and the third gear 25 have the same size, so as to ensure that the rising of the bed board 16 drives the first gear 23 and the third gear 25 to rotate the same number of circles. At the same time, the second gear 24 and the fourth gear 26 have the same size, so as to ensure that the second gear 24 and the fourth gear 26 also rotate the same number of circles, so as to ensure that the second rack 241 and the fourth rack 261 rise to the same height. The movable protection rod 245 rises, and when the bed board 16 rises, the protection rods 245 on both sides are driven to rise, so as to protect the patient and prevent the patient from falling off the bed board 16 during the transfer process and causing injury to the patient. When the bed board 16 rises to a certain height, the limit rod 263 is plugged into the limit hole 35, so that the rotating roller 31 stops rotating, ensuring that the rotating roller 31 does not rotate all the time, and preventing the patient's legs from being raised all the time. At the same time, the limit rod 263 is plugged into the limit hole 35 to stop the rotation of the limit hole 35, so as to prevent the gravity effect generated by the patient's raised legs from affecting the traction rope 311 to drive the rotating roller 31 to rotate. After the patient's legs are raised to a certain extent, the medical staff pulls out the movable sleeve 34 inside the first hole. , driving the fifth gear 33 to move, so that the fifth gear 33 is disengaged from the fourth gear 26 and no longer meshed, to prevent the patient's legs from rising all the time and causing damage to the patient. At the same time, when the patient needs to be transferred, the medical staff manually reinserts the movable sleeve 34 so that the fourth gear 26 and the fifth gear 33 are meshed again, and the patient's legs are slowly lowered in coordination with the descent of the bed board 16. When it is lowered to the lowest point, the lifting plate 313 contacts the bed board 16, which is convenient for the medical staff to move the patient's legs out. The fourth gear 26 rotates to drive the fifth gear 33 to rotate. At the same time, the fifth gear 33 is slidably connected to the rotating roller 31. The fifth gear 33 can be moved on the rotating roller 31 by pushing the movable sleeve 34. It is convenient for medical staff to control the meshing relationship between the bed board 16 and the fifth gear 33, and to control the lifting distance of the patient's legs. A groove is set at the upper end of the baffle 12, so that the protection rod 245 can be retracted into the baffle 12 when it descends, so that medical staff can transfer the patient on the bed board 16. At the same time, the protection rod 245 is extended when the bed board 16 is raised, so as to protect the patient during the transfer process and prevent the patient from being separated from the bed board 16 during the transfer and causing injury. During the transfer, the patient's personal belongings and some commonly used medicines are placed in the storage box 17, which is convenient for the patient to use and improves the practicality of the device.
