[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0020] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this utility model provides an adjustable handrail for the elderly, including a base plate 1. A support frame is fixedly installed on one side of the top of the base plate 1. The support frame is composed of a square sleeve rod 2, a square lifting rod 3, a second perforated hand-tightening bolt 16, a limiting baffle 18, and a fixed crossbar. A rotating handrail is installed between the two square lifting rods 3 at the top of the support frame. The rotating handrail is composed of a rotating rod 4, a rotating shaft 5, a supporting crossbar 7, a U-shaped sleeve rod 8, a rubber sleeve 9, and a T-shaped locking block 14. The rotating shaft 5 is fixedly installed on both ends of the rotating rod 4. A square groove 6 is opened on one end of the rotating shaft 5. A square groove 6 is opened on one side of the top of the square lifting rod 3. A through hole is provided, with one end of the rotating shaft 5 located inside the through hole. A limiting component 15 is provided at the top of the square lifting rod 3 near the outer wall of the through hole. The limiting component 15 consists of a pull rod 19, a spring 20, a square limiting block 21, a square fixing sleeve 22, and a square fixing block. The pull rod 19 and the square limiting block 21 are respectively fixed at the center of both sides of the square fixing block. The square limiting block 21 is located inside the square fixing sleeve 22. The two ends of the spring 20 are respectively fixedly connected to the outer wall of the square lifting rod 3 and one side of the square fixing block. One end of the pull rod 19 passes through the surface of the square fixing sleeve 22 and is provided with a pull ring. One end of the square limiting block 21 is located on one side of the rotating shaft 5. The square groove 6 is formed on the surface. When a person needs to use the handrail, they simultaneously pull the levers 19 on both sides of the limiting member 15, causing the square limiting block 21 to disengage from the inside of the square groove 6. At this time, when the supporting crossbar 7 is rotated to the horizontal position, the levers 19 are released. At this time, one end of the square limiting block 21 is inserted into the inside of the square groove 6 by the rebound force of the spring 20, thus fixing the supporting crossbar 7. When a person does not need to use the handrail, they simultaneously pull the levers 19 on both sides of the limiting member 15, causing the square limiting block 21 to disengage from the inside of the square groove 6. At this time, when the supporting crossbar 7 is rotated to the longitudinal position, the levers 19 are released. At this time, one end of the square limiting block 21 is inserted into the inside of the square groove 6 by the rebound force of the spring 20. The rebound force inserts into the square groove 6 to limit and fix the support crossbar 7. By rotating the handrail and the limiting part 15, the user can adjust the use state of the handrail according to their needs. The handrail can be easily opened or closed. This handrail for the elderly can be placed next to sofas, beds, or toilets. The handrail is easy to open and close, occupies little space, and is easy to move, making it suitable for various scenarios. By setting the limiting baffle 18, the supporting frame can be made more stable. At the same time, the limiting baffle 18 can block the support foot 12 set at the bottom of the support crossbar 7, preventing the support crossbar 7 from swinging when the user closes the handrail and causing unnecessary damage.

[0021] like Figure 1 , Figure 2 , Figure 3As shown, two square sleeve rods 2 are provided, symmetrically fixed to one side of the top surface of the base plate 1. A threaded mounting hole is provided on one side of the square sleeve rod 2, and a second perforated hand-tightening bolt 16 is installed inside the threaded mounting hole. A square lifting rod 3 is installed on the inner side of the top of the square sleeve rod 2. Multiple threaded limiting holes 17 are provided on the surface of the square lifting rod 3. One end of the second perforated hand-tightening bolt 16 passes through the threaded mounting hole on the surface of the square sleeve rod 2 and extends to the inner side of one of the threaded limiting holes 17 on the surface of the square lifting rod 3. Two fixed crossbars are welded between the two square lifting rods 3. The combination of the second perforated hand-tightening bolt 16, the threaded limiting holes 17, and the mounting holes allows the height of the square lifting rod 3 to be adjusted according to user needs. The welding of two fixed crossbars between the two square lifting rods 3 makes the overall support frame more stable.

[0022] like Figure 1 , Figure 2 As shown, the support crossbar 7 has sliding grooves 10 on both sides of its surface, and threaded limiting grooves 11 are evenly provided on the inner wall of the sliding grooves 10. A U-shaped sleeve 8 is fitted on the surface of the support crossbar 7, and a T-shaped locking block 14 is fixedly installed at the top of the U-shaped sleeve 8. A rubber sleeve 9 is fitted on the surface of the T-shaped locking block 14. First plum blossom hand-tightening bolts 13 are installed on both sides of the support crossbar 7. A threaded hole is provided on the surface of the U-shaped sleeve 8. One end of the first plum blossom hand-tightening bolt 13 passes through the threaded hole on the surface of the U-shaped sleeve 8 and extends to the inner side of the threaded limiting groove 11 on the surface of the support crossbar 7. The combination of sliding grooves 10, threaded limiting grooves 11, first plum blossom hand-tightening bolts 13 and threaded holes makes it easy for people to adjust the length of the handrail according to their needs.

[0023] like Figure 1 , Figure 2 As shown, a support foot 12 is fixedly installed on one side of the bottom end of the support crossbar 7; by fixing the support foot 12 on one side of the bottom end of the support crossbar 7, damage is avoided when one end of the support crossbar 7 hits the limiting baffle 18 when it is retracted.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the base plate 1 is made of thick steel plate, and a rubber suction cup is fitted on the bottom surface of the base plate 1; by fitting a rubber suction cup on the bottom surface of the base plate 1, the base plate 1 is prevented from shifting when personnel use the hand guard.

[0025] like Figure 3 As shown, anti-slip stripes are evenly distributed on the top surface of the rubber sleeve 9; by setting anti-slip stripes on the top surface of the rubber sleeve 9, the anti-slip performance of the rubber sleeve 9 is improved.
