[0030] The present invention will be further described below in conjunction with the embodiments.

[0031] Embodiment 1: In order to solve the problem that the edges of the existing turning nursing beds often lack effective protective structures when in use, resulting in the patient falling off the bed due to the armrests 142 not being lifted up during the patient turning over, the present embodiment discloses the following technical solutions, specifically as follows: Figure 1-Figure 8As shown, the bottom of the active plate 112 is fixedly connected with a connecting block 113, one side of the bevel gear 122 is meshedly connected with the bevel gear 2 123, and the two sets of bevel gear 2 123 are rotatably connected to the inside of the support frame 1, one side of the bevel gear 2 123 is fixedly connected with a screw rod 124, one side of the screw rod 124 is threadedly connected with a sliding block 125, and the sliding block 125 is slidably connected to the inside of the support frame 1, and the sliding block 125 is rotatably connected to the limit groove 13, two sets of bevel gear 4 132 are rotatably connected to the inside of the support frame 1, the bottom of the bevel gear 4 132 is fixedly connected with the screw rod 2 133, the outer side of the screw rod 2 133 is threadedly connected with a protective plate 134, the protective plate 134 is slidably connected to the inside of the limit groove 13, and the support frame 1 A connecting groove 14 is also provided at the top, and the connecting groove 14 is provided with two groups. A rotating rod 141 is rotatably connected inside the connecting groove 14. The rotating rod 141 is provided with multiple groups. The top of the rotating rod 141 is rotatably connected to an armrest 142. The bottom of the armrest 142 is slidably connected to a pressing block 143. The top of the pressing block 143 is fixedly connected to a spring rod 144, and one end of the spring rod 144 is fixedly connected to the inside of the armrest 142. A connecting rod 145 is fixedly connected to one side of the pressing block 143. A trapezoidal block 146 is slidably connected to one end of the connecting rod 145. The trapezoidal block 146 is slidably connected to the inside of the armrest 142. The bottom of the trapezoidal block 146 is fixedly connected to a limiting block 147. The rotating rod 141 is opened on one side near the top. A second limiting groove 148 is provided, and the limiting block 147 is slidably matched with the second limiting groove 148. When the patient needs to be turned over, the patient can be moved as a whole to the active plate 112 on the side where turning over is required. At this time, the motor 12 can be started, and the motor 12 drives the connecting shaft 121 to rotate, thereby rotating the two sets of bevel gears 122, and the bevel gear 122 drives the bevel gear 2 123 to rotate, thereby rotating the screw rod 124. At this time, the two sets of screw rods 124 can produce a transmission effect, thereby moving the sliding block 125. The movement of the sliding block 125 can rotate the connecting block 113 connected to the sliding block 125, thereby raising one end of the active plate 112, and at this time, the active plate 112 and the transmission plate 111 can rotate. Then, one group of active plates 112 and transmission plates 111 are raised, and the patient can be turned over. When the connection between the active plate 112 and the transmission plate 111 is raised, the bevel gear three 131 rotates, and the bevel gear three 131 drives the bevel gear four 132 to rotate, thereby rotating the screw rod 133, and the screw rod 133 drives the protective plate 134 to slide, thereby sliding the protective plate 134 inside the limiting groove 13, so that the patient is placed between the two groups of protective plates 134 to prevent the patient from falling from the support frame 1. When the armrest 142 needs to be lifted, the armrest 142 can be pulled, and the pressing block 143 is grabbed while the armrest 142 is grabbed, and the pressing block 143 moves, thereby moving the connecting rod 145.The connecting rod 145 drives the trapezoidal block 146 to move so that the limiting block 147 is disengaged from the inside of the second limiting groove 148. At this time, the armrest 142 can be pulled up. After the armrest 142 is pulled up, the pressing block 143 can be released. Under the action of the spring rod 144, the limiting block 147 moves so that the limiting block 147 moves to the inside of the second limiting groove 148, and the rotating rod 141 cannot rotate, so that the vertical height of the rotating rod 141 is fixed, so that the patient's surroundings can be protected while the patient is turning over, preventing the patient from falling.

[0032] Embodiment 2: In order to solve the problem that the existing nursing beds often lack effective protection means when adjusting the height of the bed body during use, and when the control device fails, the bed body is likely to slide down, the present embodiment discloses the following technical solutions, specifically as follows: Fig. 9 and Fig.10As shown, the interior of the nursing bed body 2 is fixedly connected to the motor 21, and the output end of the motor 21 is fixedly connected to the positive and negative threaded screw 211, the left and right ends of the positive and negative threaded screw 211 are threadedly connected to the threaded block 212, the threaded block 212 is slidably connected to the interior of the nursing bed body 2, the top of the threaded block 212 is rotatably connected to the support rod 213, the bottom of the support frame 1 is fixedly connected to the connecting plate 214, the connecting plate 214 is rotatably connected to the support rod 213, one end of the positive and negative threaded screw 211 is fixedly connected to the control rod 213, and the control rod 213 is rotatably connected to the support rod 213. The interior of the nursing bed body 2 is also fixedly connected with a spring rod 221, one end of the spring rod 221 is fixedly connected with a mounting magnet 222, and the left and right sides of the mounting magnet 222 are fixedly connected with a fixing block 223. The interior of the nursing bed body 2 is also fixedly connected with an electromagnet 224, and the electromagnet 224 is opposite to the magnetic attraction of the mounting magnet 222. The electromagnet 224 is electrically connected to the motor 21. When the height of the support frame 1 needs to be adjusted according to the patient's bed-getting method, the motor 22 can be started at this time. 1, the motor 21 drives the positive and negative threaded screw 211 to rotate, thereby moving the two groups of threaded blocks 212, and the threaded block 212 drives the support rod 213 to rotate, thereby moving the connecting plate 214, and the connecting plate 214 drives the support frame 1 to move, thereby changing the height of the support frame 1. When the motor 21 loses power due to a fault, the electromagnet 224 loses power at this time, thereby losing the attraction effect on the mounting magnet 222. At this time, under the action of the spring rod 221, the mounting magnet 222 moves to move the fixing block 223, and at this time, the fixing block 223 can fix the brake disc 22 to prevent the positive and negative threaded screw 211 from rotating. When the motor 21 is powered on, the electromagnet 224 is powered on at this time, and the electromagnet 224 is powered on, and the mounting magnet 222 is attracted, thereby releasing the fixing effect of the fixing block 223 on the brake disc 22, and at this time, the height of the support frame 1 can be changed normally, thereby achieving the effect of being able to adjust the height of the support frame 1 more safely, thereby improving the safety factor of the device.
