Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator handrail structure. Background Art

[0002] An escalator is a moving staircase that moves people between different floors of a building. There is a handrail on both sides of the escalator that moves with the escalator, and people hold it when riding the escalator to help passengers maintain their balance. There is also an emergency stop button to stop the escalator, and a key switch to restart the escalator in the upward or downward direction. At present, the handrails of escalators are not equipped with a cleaning structure. When the handrails are cleaned, they need to be cleaned manually, which is extremely inconvenient.

[0003] The patent with publication number CN212151291U discloses an escalator with a handrail self-cleaning structure, including side panels and a protective shell, wherein the protective shell and a transverse tube are fixedly connected between the two side panels, a plurality of nozzles are embedded on the lower side of the transverse tube, a guide tube is fixedly connected to the outer wall of the transverse tube, a small transmission wheel, a large transmission wheel and a special-shaped rod are arranged in the protective shell, and both ends of the small transmission wheel, the large transmission wheel and the special-shaped rod are rotatably connected to the adjacent side panels through bearings, a cleaning roller is arranged on the outer side of the special-shaped rod, and an extension tube is fixedly connected to one end surface of the cleaning roller. The utility model is an escalator with a handrail self-cleaning structure, which has the characteristics of reasonable structural design and automatic cleaning. When in use, the rotation direction of the cleaning roller is opposite to the transmission direction of the handrail belt, the velvet cover can wipe off the stains and bacteria on the surface of the handrail belt, can effectively protect public health, and the width of the cleaning roller is twice that of the handrail belt, and under the driving action of the electric telescopic rod, the idle end of the velvet cover can be rotated for cleaning.

[0004] In the specific use of the above-mentioned prior art, the velvet cover can wipe off the stains on the surface of the handrail through the relative movement between the cleaning roller and the surface of the handrail, but the velvet cover can only clean the stains on the surface of the handrail. The handrail will come into contact with different passengers during use, resulting in a large number of bacteria on the surface of the handrail. It is difficult for the velvet cover to sterilize the surface of the handrail, and there is a risk of bacterial infection. In view of this, we propose an elevator handrail structure.
