[0032] Reference Figure 1-5The utility model provides an embodiment: a safety handrail with a tensile structure for an elevator, including a ladder wall 16, a load-bearing column 10 is fixedly connected to the outer wall of the ladder wall 16, and a rotating shaft 11 is fixedly connected to the opposite end of the load-bearing column 10. The two sides of the outer wall of the rotating shaft 11 are rotatably connected to the support rod 5, and the two sides of the inner wall of the support rod 5 are provided with sliding grooves 1. The support rod 5 can achieve the effect of rotating and moving up and down by rotating the rotating shaft 11. The two sides of the inner wall of the support rod 5 are rotatably connected to the upper folding strip 13, and the bottom ends of the upper folding strip 13 are rotatable. The lower folding bar 18 is movably connected to the bottom plate 9, and the bottom end of the lower folding bar 18 is rotatably connected to the bottom plate 9. When the support rod 5 rotates and moves, the upper folding bar 13 and the lower folding bar 18 will be driven to straighten the fixed bottom plate 9 by moving and rotating. The opposite end of the bottom plate 9 is fixedly connected to the support plate 17, and the inner wall of the support plate 17 is fixedly connected to a plurality of extension rods 8. The upper folding bar 13 and the lower folding bar 18 are rotated and straightened to support the bottom plate 9 until they are parallel. After being laid flat and vertical, the extension rods 8 thereunder are vertical, so as to provide use for people of different heights.
[0033] The right telescopic rod 6 is slidably connected to the inner wall of the extension rod 8, and the left end of the right telescopic rod 6 is fixedly connected to an iron sheet 14, and the iron sheet 14 and the right end of the iron sheet 14 are provided with a magnetic sheet 15 that attracts each other, which plays the effect of fixing the left telescopic rod 19 and the right telescopic rod 6, the right end of the magnetic sheet 15 is fixedly connected to the left telescopic rod 19, and the left telescopic rod 19 is slidably connected to the inner wall of the extension rod 8, and the right telescopic rod 6 and the left telescopic rod 19 are fixedly connected to a stabilizing plate 7 at one end opposite to the left telescopic rod 19. When needed, the left telescopic rod 19 and the right telescopic rod 6 are pulled out through the inner wall of the extension rod 8 through the stabilizing plates 7 at both ends, and the stabilizing plates 7 are stretched to provide more people with use, the left end of the support rod 5 is fixedly connected to a handle 3, and the outer wall of the handle 3 is fixedly connected to an anti-skid sleeve 4, so that it plays an anti-skid role when in use, and the outer wall of the support rod 5 is fixedly connected to a suction cup 2 at one end, and the ladder wall 16 can be sucked by the suction cup 2 when it is not in use. The load-bearing column 10 is fixedly connected to a support block 12 at one end opposite to the support rod 10.
[0034] Working principle: when it is needed, first separate the suction cup 2 from the ladder wall 16, and drive the support rod 5 connected to the outer wall of the rotating shaft 11 to rotate through the rotating shaft 11 fixedly connected to the opposite end of the load-bearing column 10. When the support rod 5 is lowered to a horizontal plane, the support block 12 at the bottom end of the load-bearing column 10 will be stuck. At the same time, when the support rod 5 is lowered, the upper folding strip 13 on the inner wall will rotate and stretch, and the lower folding strip 18 will be stretched through the upper folding strip 13. At the same time, the lower folding strip 18 is rotatably connected to both sides of the bottom plate 9 to achieve a stabilizing effect. The bottom plate 9 is fixedly connected to a support plate 17 at one end, and a plurality of extension rods 8 are fixedly connected to the inner wall of the support plate 17. The upper folding strip 13 and the lower folding strip 18 are rotated and straightened to support the bottom plate 9 until it is parallel, and then laid flat and vertical. After the straightening, the extension rod 8 below it is vertical, so that it can be used by people of different heights. When there are too many people using it or it is inconvenient to hold the handrail, the right telescopic rod 6 and the left telescopic rod 19 can be pulled out through the stabilizing plates 7 on both sides to achieve the effect of extended use. After use, the left end of the right telescopic rod 6 is fixedly connected with an iron sheet 14, and the iron sheet 14 and the magnetic sheet 15 fixedly connected to the right end of the left telescopic rod 19 attract each other, which plays the effect of fixing the left telescopic rod 19 and the right telescopic rod 6. When it is not needed, the left telescopic rod 19 and the right telescopic rod 6 can be retracted to the inner wall of the extension rod 8, and the iron sheet 14 and the magnetic sheet are fixed after mutual attraction. At the same time, the handle 3 is lifted, the upper folding strip 13 and the lower folding strip 18 are recovered, and the suction cup 2 on the support rod 5 is used to suck the ladder wall 16, which can save space.
