Description

Technical Field

[0001] The utility model belongs to the technical field of escalators, and in particular relates to an anti-wear mechanism for a handrail of an escalator. Background Art

[0002] With the development of society, the progress of the times, and the continuous improvement of people's living standards, the use of escalators has become increasingly frequent. An escalator, also known as an automatic pedestrian elevator, escalator, or escalator, is a means of transporting pedestrians using a conveyor belt. Escalators are generally inclined. Pedestrians step onto the automatically moving steps at one end of the escalator and are automatically taken to the other end, with the steps remaining level along the way. Escalators are equipped with handrails on both sides that move synchronously with the steps for users to hold on to. Application number CN202020537641.1 is an escalator handrail wear-resistant mechanism, including an elevator handrail and a mounting platform. The elevator handrail is sleeved and mounted on the top of the mounting platform. Fixed blocks are fixedly mounted on both sides of the mounting platform. A cleaning plate is fixedly mounted on the side away from each other of the two fixed blocks. A slot is defined inside the top of the elevator handrail. An insert block is inserted into the slot. A rubber pad is fixedly mounted at the bottom of the insert block. A cavity is defined inside the insert block. A spring is fixedly mounted inside the cavity. A limit column is fixedly mounted on the top of the spring. A limit groove is defined at the top of the slot. A cleaning brush can be used to clean the elevator handrail when it moves to the position of the cleaning plate, wiping off dust accumulated on the surface of the elevator handrail, improving the cleanliness of the device and making people more comfortable when using it.

[0003] The above-mentioned escalator handrail uses a cleaning brush to clean the surface dust, which increases the comfort of use. However, it has the following defects: (1) The anti-wear mechanism of the escalator handrail adopts a cleaning brush for cleaning. The cleaning brush is prone to wear, resulting in a gap between the end of the brush and the handrail, and the handrail surface cannot be cleaned normally. For this reason, we propose an anti-wear mechanism for the escalator handrail. Utility Model Content

[0007] Preferably, the cross sections of the guide rod and the guide hole are both circular structures, and the central axes of the guide hole and the guide rod coincide with each other.

[0008] Preferably, a retaining groove is formed on the side wall of the connecting column, a retaining block is provided inside the retaining groove, and the retaining block is fixed on the inner wall of the connecting cylinder.

[0009] Preferably, the cross sections of the connecting tube and the connecting column are both circular structures, and the central axes of the connecting tube and the connecting column coincide with each other.

[0010] Preferably, ribs are fixed to the end faces of the connecting tube and the connecting column respectively, and the cross-section of the ribs is a triangular structure.

[0011] Preferably, a spherical groove is provided on the inner wall of the armrest, and a ball is embedded in the spherical groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) The bristles are installed on the surfaces of the first cleaning plate and the second cleaning plate respectively through the designed first cleaning plate, second cleaning plate, connecting column, connecting tube and spring. The two cleaning plates can be movably installed on the inner side of the outer frame through the cooperation of the connecting column and the connecting tube. The spring applies elastic force to the connecting column, thereby pushing the bristles on the cleaning plate to always keep in contact with the surface of the handrail, achieving the purpose of cleaning and preventing the bristles from being worn and causing gaps that affect the cleaning effect of the elevator handrail.
