[0022] In one embodiment, as Figures 1-6 shown, a building aging-friendly renovation stairwell device includes a load-bearing base ①, and a plurality of support plates ② are fixedly connected to the top surface of the load-bearing base ①. The plurality of support plates ② are linearly arranged at equal intervals from left to right in sequence, and the heights of the plurality of support plates ② decrease at equal intervals from left to right. The top surface of each support plate ② and the right side of the load-bearing base ① are fixedly connected with a stair tread ③. Through holes are opened on the front and rear sides of each stair tread ③, and a lifting screw rod ④ is sleeved in the through hole by a bearing. The upper end of the surface of the lifting screw rod ④ is threadedly sleeved with a threaded pipe ⑤, and the upper end surface of the threaded pipe ⑤ is fixedly connected with a handrail ⑥. The handrail ⑥ is inclined with the left side high and the right side low. The lower end surface of the lifting screw rod ④ is fixedly connected with a turning handle ⑦. The opposite surfaces of the left and right adjacent handrails ⑥ are commonly fixedly connected with a connecting screw rod ⑧. The opposite ends of the surfaces of the left and right adjacent connecting screw rods ⑧ are commonly threadedly sleeved with a threaded sleeve ⑨, and a hexagonal nut ⑩ is fixedly sleeved in the middle of the surface of the threaded sleeve ⑨.

[0023] In order to fix the lifting screw rod 4 so that the lifting screw rod 4 will not rotate automatically or accidentally due to touching, and to improve the stability after the height adjustment of the handrail 6, a connecting disc 11 is fixedly sleeved on the lower end of the surface of each lifting screw rod 4. A plurality of threaded holes 12 are formed in the side surface of the connecting disc 11. The plurality of threaded holes 12 are arranged in an annular array with respect to the axis line of the lifting screw rod 4. A connecting block 13 is fixedly connected to the bottom surface of each stair tread 3 near the right side. A fixing screw rod 14 is threadedly sleeved in the middle of the connecting block 13. The left end of the fixing screw rod 14 is inserted into the adjacent threaded hole 12, and a knob 15 is fixedly connected to the right end surface of the fixing screw rod 14.

[0024] In order to improve the anti-slip effect when the elderly walk on the stair tread 3, a first anti-slip pad 16 is fixedly connected to the top surface of the stair tread 3, and a second anti-slip pad 17 is fixedly sleeved on the surface of the handrail 6. The first anti-slip pad 16 increases the anti-slip effect when the elderly step on the stair tread 3, and the second anti-slip pad 17 increases the anti-slip effect when the elderly hold the handrail 6.

[0025] In order to facilitate the fixing of the device on the wall and improve the stability after the device is placed, a connecting plate 18 is fixedly connected to the left side of the bottom surface of the leftmost stair tread 3. A plurality of connecting holes 19 are formed in the middle of the connecting plate 18, and expansion bolts 20 are movably sleeved in the connecting holes 19.

[0026] In order to prevent the threaded pipe 5 from rotating along with the lifting screw rod 4, movable blocks 21 are fixedly connected to the left and right sides of the lower end of the outer surface of each threaded pipe 5. An activity hole is formed in the middle of each movable block 21, and a guide rod 22 is movably sleeved in the activity hole. The lower end surface of the guide rod 22 is fixedly connected to the top surface of the stair tread 3.

[0027] In order to improve the stability of the stair tread 3 and prevent the right side of the stair tread 3 from bending downward, a support block 23 is fixedly connected to the right side of the bottom surface of each stair tread 3. The bottom surface of the support block 23 is fixedly connected to the left side of the top surface of the adjacent stair tread 3. The support block 23 can support the right side of the stair tread 3 except the rightmost one.

[0028] In order to facilitate the pushing of the device for movement, first universal wheels 24 are fixedly connected to the four corners of the bottom surface of the load-bearing base 1. Second universal wheels 25 are fixedly connected to the front and rear sides of the right side of the bottom surface of the rightmost stair tread 3. The second universal wheels 25 can support the right side of the rightmost stair tread 3, so that the right side of the left and right stair treads 3 is not prone to bending downward.

[0029] Working principle: When the utility model is in use, first use a wrench to twist the hexagonal nut 10 to rotate the threaded sleeve 9, so that the threaded sleeve 9 moves away from one of the connecting screws 8, releasing the connection between the two armrests 6. Then twist the knob 15 to rotate the fixing screw 14. The rotation of the fixing screw 14 will move to the right, pulling the left end of the fixing screw 14 out of the threaded hole 12 and releasing the fixation of the connection plate 11. Then twist the turning handle 7 to rotate the lifting screw 4. The rotation of the lifting screw 4 makes the threaded tube 5 move up and down, and the threaded tube 5 drives the armrest 6 to move up and down, thereby adjusting the height of the armrest 6, enabling the armrest 6 to be adjusted in real time according to the differences in the physical conditions of the elderly, thus improving its adaptability and comfort. After adjusting the heights of all the armrests 6, first twist the knob 15 in the reverse direction to make the fixing screw 14 move to the left and insert it into the corresponding threaded hole 12 to fix the connection plate 11, making the lifting screw 4 unable to rotate, thereby improving the stability of the armrest 6 after adjustment. Then use a wrench to twist the hexagonal nut 10 in the reverse direction to make the threaded sleeve 9 simultaneously sleeved on two adjacent armrests 6, thereby connecting the armrests 6 on the same side into a whole, improving the stability of the armrest 6 and making the armrest 6 not prone to shaking. It is convenient to push and move the position through the first universal wheel 24 and the second universal wheel 25. After the device moves to the designated location, the first universal wheel 24 and the second universal wheel 25 are self-locked. At this time, the left side of the leftmost stair tread 3 is in contact with the high wall. A hole is pre-drilled at a position on the high wall corresponding to the connection hole 19. Then insert the expansion bolt 20 into the hole in the wall to fix the device, making it difficult to move the device after it is placed.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0031] The above embodiments only represent several implementation manners of the utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
