[0014] A method for using a turning aid for disabled elderly people, used to implement the above-mentioned turning aid for disabled elderly people: S1: First, pull apart the columns on both sides through the scissor-type connecting rod, then remove the first connecting rod and the second connecting rod from the first buckle and the second buckle, then screw one end of the first connecting rod into the connecting sleeve at the end of the second connecting rod through the matching relationship between the threads, then align the side without the folding component installed with the bed body and slide it in through the universal movable wheel, so that the flexible bed sheet falls above the bed surface. Since the height of the two reel rollers will be slightly higher than the bed surface, the flexible bed sheet will form a U-shaped state. At this time, align the two ends of the assembled first connecting rod and the second connecting rod with the threaded sleeve on the same side, and fix the columns on both sides by rotation.

[0015] S2: After fixing the column, insert a screwdriver or a steel pipe into the through hole opened on the outside of the rotating part to drive the rotating part to rotate. After the rotating part rotates, it will synchronously drive the driving rods on both sides to rotate. When the driving rods rotate, they will drive the worm to rotate. When the worm rotates, it will drive the rotating sleeve to rotate through the meshing relationship with the worm wheel. When the rotating sleeve rotates, it drives the threaded rod to rise and fall through the threaded connection relationship. When the threaded rod is lifted and lowered, it will pull the universal moving wheel to move. As the universal moving wheel is lifted, the bottom of the support column will contact the ground, so that the column will not slide easily, thereby improving the stability of the device.

[0016] S3: When it is necessary to assist a disabled elderly person to turn over, the output end of the reducer will drive the driving wheel to rotate, and the driving wheel will drive the driven wheel to rotate through the transmission belt. The driven wheel will drive the reel roller to reel up the flexible bed sheet. The reel rollers on both sides will cooperate with each other and rotate in the same direction. Since the flexible bed sheet is U-shaped, as the reel roller continues to reel up, the elderly will gradually move from the middle of the bed to the side of the bed, and at this time the elderly's state will gradually change from lying flat to tilted, thereby assisting the elderly to turn over.

[0017] S4: When the device is not needed, the first connecting rod and the second connecting rod must be unscrewed from between the threaded sleeves, and then the first connecting rod must be unscrewed from the connecting sleeves, and then the first connecting rod and the second connecting rod must be re-engaged in the first buckle and the second buckle, and then the rotating part is driven to rotate, so that the threaded rod drives the universal moving wheel to move downward so that the support column is suspended in the air, and at this time, the front and rear columns are pushed closer to each other, so that the scissor-type connecting rods are folded together to complete the storage of the device.

[0018] Compared with the prior art, the advantages of the present invention are: 1. The present invention drives the reel roller to reel up the flexible bed sheet through a speed reducer. The driving wheel and the driven wheel are linked by a transmission belt, and the reel rollers on both sides rotate synchronously to ensure a smooth and unstuck turning process, so that the elderly can turn over independently without manual handling or manual adjustment of body position, which significantly reduces the labor intensity of turning over at night for nursing staff, greatly reduces the workload of nursing staff, saves time and energy, and reduces labor costs. The invention can help the elderly turn over regularly and appropriately, effectively prevent the occurrence of bedsores, and protect the skin health of the elderly.

[0019] 2. The mobile component of the present invention adopts a threaded rod structure with a worm gear drive, and the universal wheel is driven to rise and fall through a rotating part. When in use, the support column touches the ground to provide stable support. When moving, the universal wheel touches the ground to facilitate the device to slide under the bed, taking into account both stability and flexibility. The folding component realizes rapid expansion and folding of the column through a scissor-type connecting rod. After storage, the volume is small, which is suitable for storage in limited space at home or in a ward. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A method for using a turning aid for disabled elderly people, used to implement the above-mentioned turning aid for disabled elderly people: S1: First, the columns 1 on both sides are pulled apart by the scissor-type connecting rod 2102. After pulling apart, the first connecting rod 13 and the second connecting rod 15 are removed from the first buckle 12 and the second buckle 14. Then, one end of the first connecting rod 13 is screwed into the connecting sleeve 16 at the end of the second connecting rod 15 through the matching relationship between the threads. Next, the side where the folding component 21 is not installed is aligned with the bed body and slid in through the universal movable wheel 2009, so that the flexible bed sheet 5 falls above the bed surface. Since the height of the two reel rollers 4 is slightly higher than the bed surface, the flexible bed sheet 5 will form a U-shaped state. At this time, the two ends of the assembled first connecting rod 13 and the second connecting rod 15 are aligned with the threaded sleeve 17 on the same side, and the columns 1 on both sides are fixed by rotation.

[0033] S2: After fixing the column 1, insert a screwdriver or a steel pipe into the through hole provided on the outer side of the rotating member 18 so as to drive the rotating member 18 to rotate. After the rotating member 18 rotates, it will synchronously drive the driving rods 2014 on both sides to rotate. When the driving rods 2014 rotate, it will drive the worm 2007 to rotate. When the worm 2007 rotates, it will drive the rotating sleeve 2005 to rotate through the meshing relationship with the worm wheel 2006. When the rotating sleeve 2005 rotates, it will drive the threaded rod 2008 to rise and fall through the threaded connection relationship. When the threaded rod 2008 rises and falls, it will pull the universal moving wheel 2009 to move. As the universal moving wheel 2009 is lifted, the bottom of the support column 2003 will contact the ground, so that the column 1 will not slide easily, thereby improving the stability of the device.

[0034] S3: When it is necessary to assist a disabled elderly person to turn over, the output end of the reducer 7 will drive the driving wheel 8 to rotate, and the driving wheel 8 will drive the driven wheel 9 to rotate through the transmission belt 10 when rotating. The driven wheel 9 will drive the reel roller 4 to reel up the flexible bed sheet 5. The reel rollers 4 on both sides will cooperate with each other when rotating and will rotate in the same direction. Since the flexible bed sheet 5 is U-shaped, as the reel roller 4 continues to reel up, the elderly will gradually move from the middle of the bed to the side of the bed, and at this time the elderly's state will gradually change from lying flat to tilted, thereby assisting the elderly to turn over.

[0035] S4: When the device is not needed, the first connecting rod 13 and the second connecting rod 15 must be unscrewed from between the threaded sleeve 17, and then the first connecting rod 13 must be unscrewed from the connecting sleeve 16, and then the first connecting rod 13 and the second connecting rod 15 must be re-engaged in the first buckle 12 and the second buckle 14, and then the rotating member 18 is driven to rotate, so that the threaded rod 2008 drives the universal movable wheel 2009 to move downward so that the support column 2003 is suspended, and at this time, the front and rear columns 1 are pushed closer to each other, so that the scissor-type connecting rod 2102 is folded together to complete the storage of the device.

9. A turning aid for disabled elderly people according to any one of claims 1 to 5, characterized in that: The folding assembly (21) comprises two groups of installation boxes (2101), the two groups of installation boxes (2101) are respectively fixedly connected to the sides of the two front and rear columns (1), a scissor-type connecting rod (2102) is arranged between the two groups of installation boxes (2101), and a sliding groove (2103) is penetrated through the upper ends of the two groups of installation boxes (2101), the upper ends of the front and rear sides of the scissor-type connecting rod (2102) are slidably connected to the two groups of sliding grooves (2103) through a first rotating shaft (2104), and the lower ends of the front and rear sides of the scissor-type connecting rod (2102) are rotatably connected to the lower ends of the two groups of installation boxes (2101) through a second rotating shaft (2105).

10. A method for using a turning aid for disabled elderly people, used to implement the turning aid for disabled elderly people as claimed in claims 1-9, characterized in that: S1: First, the columns (1) on both sides are pulled apart by means of a scissor-type connecting rod (2102). After the columns (1) are pulled apart, the first connecting rod (13) and the second connecting rod (15) are removed from the first buckle (12) and the second buckle (14). Then, one end of the first connecting rod (13) is screwed into the connecting sleeve (16) at the end of the second connecting rod (15) through the matching relationship between the threads. Then, the side on which the folding assembly (21) is not installed is aligned with the bed body and slid in through the universal movable wheel (2009) so that the flexible bed sheet (5) falls above the bed surface. Since the height of the two reel rollers (4) is slightly higher than the bed surface, the flexible bed sheet (5) will form a U-shaped state. At this time, the ends of the assembled first connecting rod (13) and the second connecting rod (15) are aligned with the threaded sleeve (17) on the same side, and the columns (1) on both sides are fixed by rotation. S2: After fixing the column (1), a screwdriver or a steel pipe is inserted into the through hole provided on the outer side of the rotating member (18) so as to drive the rotating member (18) to rotate. After the rotating member (18) rotates, it will synchronously drive the driving rods (2014) on both sides to rotate. When the driving rods (2014) rotate, it will drive the worm (2007) to rotate. When the worm (2007) rotates, it will drive the rotating sleeve (2005) to rotate through the meshing relationship with the worm wheel (2006). When the rotating sleeve (2005) rotates, it will drive the threaded rod (2008) to move up and down through the threaded connection relationship. When the threaded rod (2008) is moved up and down, it will pull the universal moving wheel (2009) to move. As the universal moving wheel (2009) is lifted, the bottom of the support column (2003) will contact the ground, so that the column (1) will not slide easily, thereby improving the stability of the device; S3: When it is necessary to assist the disabled elderly to turn over, the output end of the reducer (7) drives the driving wheel (8) to rotate. When the driving wheel (8) rotates, it drives the driven wheel (9) to rotate through the transmission belt (10). When the driven wheel (9) rotates, it drives the reel roller (4) to reel up the flexible bed sheet (5). When the reel rollers (4) on both sides rotate, they cooperate with each other and rotate in the same direction. Since the flexible bed sheet (5) is U-shaped, as the reel roller (4) continues to reel up, the elderly will gradually move from the middle of the bed to the side of the bed, and at this time, the elderly's state will gradually change from lying flat to tilted, thereby assisting the elderly to turn over; S4: When the device is not needed, the first connecting rod (13) and the second connecting rod (15) must first be unscrewed from between the threaded sleeve (17), and then the first connecting rod (13) must be unscrewed from the connecting sleeve (16), and then the first connecting rod (13) and the second connecting rod (15) must be re-engaged in the first buckle (12) and the second buckle (14), and then the rotating member (18) is driven to rotate, so that the threaded rod (2008) drives the universal movable wheel (2009) to move downward, thereby making the support column (2003) suspended in the air, and then the front and rear columns (1) are pushed closer to each other, so that the scissor-type connecting rod (2102) is folded together, and the storage of the device is completed.
