[0027] Example 1, such as Figure 1 As shown, a fall-prevention nursing support includes a base 1, four casters 2 rotatably connected to the base 1, two telescopic columns 3 fixedly connected to the base 1, a lifting frame 4 fixedly connected to the two telescopic columns 3, an electric telescopic rod 5 fixedly connected to the base 1, one end of the electric telescopic rod 5 fixedly connected to the lifting frame 4, two handles 6 fixedly connected to the lifting frame 4, two elbow supports 7 fixedly connected to the lifting frame 4, and a stabilizing block 10 fixedly connected to the two telescopic columns 3.
[0028] Reference Figure 2 and Figure 3The support structure 8 is mainly composed of two rotating shafts 81, both of which are rotationally connected to the stable block 10. The rotating shaft 81 is fixedly connected with a connecting block 82, the connecting block 82 is fixedly connected with a support plate 83, the support plate 83 is fixedly connected with a soft pad 84. The user holds the two handles 6 with both hands and places the elbows on the two elbow supports 7, and then starts the electric telescopic rod 5. The piston rod of the electric telescopic rod 5 drives the lifting frame 4 to rise, thereby assisting the user to stand up. The user can rotate the two rotating shafts 81 to drive the support plate 83 to rotate to a horizontal state during walking to sit down. The soft pad 84 can improve comfort. Usually, the two support plates 83 are in a vertical state, thereby avoiding the current anti-falling nursing support which usually supports the patient through lifting clamps and provides certain support during patient movement. However, the patient cannot sit down before reaching the target position. If the patient's legs cannot support during the process, it is easy to cause the patient to fall and be injured. The stable block 10 is rotationally connected with a rotating shaft 85, and the rotating shaft 85 is fixedly connected with a gear 86 on one rotating shaft 81. The two gears 86 are meshed with each other. Rotating the rotating shaft 85 can drive one gear 86 to rotate, thereby driving the other gear 86 to rotate in the opposite direction. The rotating shaft 85 is fixedly connected with a belt pulley 87 on one rotating shaft 81. The two belt pulleys 87 are commonly provided with a transmission belt 88. Rotating the rotating shaft 85 drives one belt pulley 87 to rotate. The two belt pulleys 87 rotate synchronously under the action of the transmission belt 88, thereby making the two rotating shafts 81 rotate synchronously in the opposite direction. The stable block 10 is fixedly connected with a motor 812. The output shaft of the motor 812 is fixedly connected with one rotating shaft 81. Starting the motor 812 drives the rotating shaft 81 to rotate, making the operation more convenient. The motor 812 is a servo motor, which can control the rotation angle through the built-in encoder and has a self-locking mechanism. After the power is turned off, it still remains at the current position to support the support plate 83 and the user. The stable block 10 is fixedly connected with two first air cylinders 89. The piston rod of the first air cylinder 89 is fixedly connected with a clamping block 810. The connecting block 82 is provided with a clamping groove 811. Simultaneously starting the two first air cylinders 89, the piston rod of the first air cylinder 89 drives the clamping block 810 to advance, which can clamp the clamping block 810 into the corresponding clamping groove 811 to limit the support plate 83, thereby further improving the support effect.
[0029] Referring to Figure 4The base 1 is provided with a limiting structure 9, the limiting structure 9 is mainly composed of two rectangular plates 91, the two rectangular plates 91 are arranged on the two sides of the base 1 respectively, the second cylinder 92 is fixedly connected on the rectangular plate 91, the piston rod of the second cylinder 92 is fixedly connected with a limiting plate 93, the rubber pad is fixedly connected on the limiting plate 93, after the user reaches the designated position, the two second cylinders 92 can be started at the same time to drive the limiting plate 93 to descend, so that the rubber pad is tightly attached to the ground, and the base 1 is limited, the two round rods 94 are fixedly connected on the limiting plate 93, the round rod 94 is slidingly connected with the rectangular plate 91, the two round rods 94 are limited to slide on the rectangular plate 91, so that the moving process of the limiting plate 93 is more stable, the connecting grooves 95 are respectively arranged on the two sides of the base 1, the two pins 97 are slidingly arranged on the base 1, the two sides of the rectangular plate 91 are respectively provided with the insertion grooves 96, the rectangular plate 91 is clamped into the connecting grooves 95, then the pins 97 are inserted into the insertion grooves 96, and the rectangular plate 91 can be limited, so that the rectangular plate 91 is convenient to install and disassemble.
[0030] The working principle is that the user holds the two handles 6 with both hands and places the elbows on the two elbow supports 7, and then starts the electric telescopic rod 5. The piston rod of the electric telescopic rod 5 drives the lifting frame 4 to rise, thereby assisting the user to stand up. The user can rotate the two rotating shafts 81 to drive the support plates 83 to rotate to a horizontal state when tired during walking, so as to provide a place for the user to sit down. The soft pad 84 can improve the comfort. Normally, the two support plates 83 are in a vertical state, thereby avoiding the situation that the current anti-falling nursing support usually supports the patient through a lifting clamp, and provides certain support to the patient during movement. However, the patient cannot sit down before reaching the target position. If the patient's legs cannot support during the movement, the patient is easy to fall and be injured. Rotating the rotating shaft 85 can drive one gear 86 to rotate, thereby driving the other gear 86 to rotate in the opposite direction. The rotating shaft 85 drives one belt pulley 87 to rotate. Under the action of the transmission belt 88, the two belt pulleys 87 rotate synchronously, thereby making the two rotating shafts 81 rotate synchronously in the opposite direction. Starting the motor 812, the output shaft of the motor 812 drives the rotating shaft 81 to rotate, so that the operation is more convenient. The motor 812 is a servo motor, which can control the rotation angle through the built-in encoder, and is built-in with a self-locking mechanism. After the power is turned off, it still remains at the current position to support the support plate 83 and the user. At the same time, start the two first cylinders 89. The piston rod of the first cylinder 89 drives the clamping block 810 to move forward, which can clamp the clamping block 810 into the corresponding clamping groove 811 to limit the support plate 83, thereby further improving the support effect. After the user reaches the specified position, the two second cylinders 92 can be started at the same time to drive the limiting plate 93 to descend, so that the rubber pad is tightly attached to the ground to limit the base 1. The two round rods 94 slide on the rectangular plate 91, so that the movement of the limiting plate 93 is more stable. Clamping the rectangular plate 91 into the connecting groove 95, and then inserting the bolt 97 into the slot 96, the rectangular plate 91 can be limited, which is convenient for installation and disassembly.
