Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0023] A nursing and rescue device includes a stretcher body 1 and further includes a lifting plate 2. The lifting plate 2 is located on the stretcher body 1, and the lifting plate 2 is used to lift the stretcher body 1 moving in a staircase environment.

[0024] A deformation mechanism 3 is provided on the stretcher body 1. By controlling the movement of the lifting plate 2 through the deformation mechanism 3, the stretcher body 1 moving in a staircase environment is lifted.

[0025] The advantage of setting the deformation mechanism 3 is that when the staff is carrying the stretcher body 1 and walking in a staircase environment, the stretcher body 1 can be lifted by driving the movement of the lifting plate 2 at one end of the stretcher body 1, so that the stretcher body 1 remains balanced front and back, thereby improving the stability of the stretcher body 1 during movement. Further, it makes the staff more stable and convenient when moving the patient, and the height adjustment is manually controlled, making the device more flexible to use.

[0026] The deformation mechanism 3 includes a power member 4 provided on the stretcher body 1, which provides power for the movement of the lifting plate 2. An unfolding member 5 is provided on the stretcher body 1 to control the moving direction of the lifting plate 2. A lifting member 6 is provided on the unfolding member 5 to drive the movement of the lifting plate 2.

[0027] The power member 4 includes a fixing plate 41 provided on the stretcher body 1. A power groove 42 is formed on the fixing plate 41. An extension groove 43 is formed on the stretcher body 1, and the extension groove 43 penetrates the power groove 42. A power shaft 44 is rotatably provided in the extension groove 43. One end of the power shaft 44 extends into the power groove 42. An extension plate one 45 is provided on the fixing plate 41. A linkage shaft 46 is rotatably provided on the extension plate one 45. Power pulleys 47 are provided on both the linkage shaft 46 and the power shaft 44, and a power belt 48 is provided on the power pulley 47.

[0028] The advantage of setting the power member 4 is that the lifting plate 2 can be manually driven to move, making the device more flexible during use and capable of quickly adjusting the level of the stretcher body 1 according to the moving environment.

[0029] When encountering a staircase environment, the staff first rotates the lifting rod 68 connected to the linkage shaft 46 among the multiple lifting rods 68, further driving the rotation of the linkage shaft 46. While the linkage shaft 46 rotates, it drives the power pulley 47 provided on it to rotate. Synchronously, the power pulley 47 provided on the power shaft 44 is driven to rotate through the power belt 48, and finally drives the power shaft 44 to rotate in the extension groove 43.

[0030] The unfolding member 5 includes an unfolding plate 51 provided at one end of the stretcher body 1 away from the fixing plate 41. An unfolding groove 52 is formed on the unfolding plate 51. The power shaft 44 extends into the unfolding groove 52 and is rotatably connected to the unfolding groove 52. An unfolding gear one 53 is provided at one end of the power shaft 44 located in the unfolding groove 52. A bidirectional lead screw 54 is rotatably provided in the unfolding groove 52, and an unfolding gear two 55 engaged with the unfolding gear one 53 is provided on the bidirectional lead screw 54.

[0031] The advantage of setting the unfolding member 5 is that it can be more stable when controlling the movement of the lifting plate 2. While the power shaft 44 rotates, it drives the unfolding gear one 53 provided on it to rotate. While the unfolding gear one 53 rotates, it drives the unfolding gear two 55 engaged with it on the bidirectional lead screw 54 to rotate. While the unfolding gear two 55 rotates, it drives the bidirectional lead screw 54 to rotate synchronously.

[0032] The lifting member 6 includes a moving block 61 disposed on the bidirectional lead screw 54. The moving block 61 is threadedly connected to the bidirectional lead screw 54. A first connecting rod 62 and a second connecting rod 63 are rotatably disposed on the moving block 61. A rotating shaft 64 is rotatably disposed on the first connecting rod 62. The rotating shaft 64 is rotatably connected to the second connecting rod 63. A plurality of sliding grooves 65 are formed in the lifting plate 2. A sliding seat 66 is slidably disposed in each of the plurality of sliding grooves 65. The plurality of sliding seats 66 are respectively rotatably connected to the first connecting rod 62 and the second connecting rod 63. An extension plate two 67 is disposed on the lifting plate 2. Lifting rods 68 are disposed on the extension plate one 45, the extension plate two 67 and the linkage shaft 46.

[0033] The rotation of the bidirectional lead screw 54 drives the plurality of moving blocks 61 disposed thereon and threadedly connected thereto to move towards each other, thereby driving the first connecting rod 62 and the second connecting rod 63 to rotate around the rotating shaft 64. While the first connecting rod 62 and the second connecting rod 63 are rotating, they drive the sliding seat 66 to move in the sliding groove 65, thereby pushing the lifting plate 2 to move and lifting the stretcher body 1.

[0034] Retractable straps 7 are disposed on both the fixing plate 41 and the unfolding plate 51.

[0035] The advantage of setting the strap 7 is that when encountering a patient with a large body weight, it can make it easier for the staff to lift the stretcher body 1 and make it more stable when the staff carries the stretcher body 1 and moves.

[0036] During use, when encountering a staircase environment, the staff first rotates the lifting rod 68 connected to the linkage shaft 46 among the plurality of lifting rods 68, further driving the linkage shaft 46 to rotate. While the linkage shaft 46 is rotating, it drives the power pulley 47 disposed thereon to rotate, and synchronously drives the power pulley 47 disposed on the power shaft 44 to rotate through the power belt 48, and finally drives the power shaft 44 to rotate in the extension groove 43.

[0037] While the power shaft 44 is rotating, it drives the first unfolding gear 53 disposed thereon to rotate. While the first unfolding gear 53 is rotating, it drives the second unfolding gear 55 engaged with it on the bidirectional lead screw 54 to rotate. While the second unfolding gear 55 is rotating, it drives the bidirectional lead screw 54 to rotate synchronously.

[0038] The rotation of the bidirectional lead screw 54 drives the plurality of moving blocks 61 disposed thereon and threadedly connected thereto to move towards each other, thereby driving the first connecting rod 62 and the second connecting rod 63 to rotate around the rotating shaft 64. While the first connecting rod 62 and the second connecting rod 63 are rotating, they drive the sliding seat 66 to move in the sliding groove 65, thereby pushing the lifting plate 2 to move and lifting the stretcher body 1.
