Description

Technical Field

[0001] This utility model relates to the field of handrail technology, and in particular to a handrail with scratch warning. Background Technology

[0002] In escalators and moving walkways, handrails play a crucial role in providing support for passengers. However, during operation, handrails frequently scrape against other components. The two lips and outer sides of the handrail, in particular, are more prone to friction with surrounding metal parts (such as handrail rails and decorative panel edges) due to their location and structural characteristics. Prolonged scraping leads to handrail wear, affecting not only its appearance but also its lifespan. In severe cases, it can even cause safety accidents, such as handrail breakage leading to passenger falls. Currently, there is a lack of a device that can effectively detect and alert passengers to handrail scraping, making it difficult to identify and address problems in their early stages. This results in frequent abnormal wear and tear on handrails caused by scraping. Utility Model Content

[0003] The purpose of this invention is to provide a handrail with a scratch warning system that can detect scratches on the handrail in a timely manner and provide dual warnings with light and sound. This effectively prevents excessive wear caused by long-term scratching, extends the service life of the handrail, and reduces equipment maintenance costs. This solves the problem that existing handrails cannot provide timely warnings when scratched, leading to severe abnormal wear.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a handrail with scratch warning, comprising a handrail body; wherein: an LED light group is embedded in the flat portion of the handrail body; a conductive element is provided on the arc-shaped side of the handrail body or at the lip of the handrail body; a wire is built into the handrail body; the conductive element is electrically connected to the LED light group through the wire to form a control circuit; when the lip of the handrail body or the arc-shaped side of the handrail body scratches a metal object, the conductive element is activated, the control circuit forms a closed loop, and the LED light group lights up.

[0009] As a further improvement to the technical solution of this utility model, a buzzer is also provided on the handrail body. The buzzer is connected in parallel with the control circuit and is used to issue an audible alarm when a scratch occurs.

[0010] As a further improvement to the technical solution of this utility model, the battery is a rechargeable battery, and the handrail body is provided with a charging interface to facilitate charging and maintenance of the battery.

[0011] As a further improvement to the technical solution of this utility model, the handrail body includes a wear-resistant layer, a conductive layer and an insulating layer. The wear-resistant layer is located on the outermost layer, the conductive layer is located between the wear-resistant layer and the insulating layer, and the conductive element is embedded in the conductive layer to ensure that each component functions normally and does not interfere with each other.

This facilitates the detection of scratches and timely removal of abnormal scratches, reducing abnormal wear on the handrail belt. This invention can promptly detect handrail belt scratches and provides dual alerts with both light and sound, effectively preventing excessive wear caused by prolonged scratching, extending the handrail belt's lifespan, and reducing equipment maintenance costs.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a handrail with scratch warning, comprising a handrail body 1; wherein: an LED light group 2 is embedded in the flat part of the handrail body 1; a conductive element 3 is provided on the arc-shaped side 11 of the handrail body 1 or at the lip 12 of the handrail body 1; a wire 4 is built into the handrail body 1; the conductive element 3 is electrically connected to the LED light group 2 through the wire 4 to form a control circuit; when the lip 12 of the handrail body 1 or the arc-shaped side 11 of the handrail body 1 scratches a metal scratching object 5, the conductive element 3 is turned on, the control circuit forms a closed loop, and the LED light group 2 lights up. This invention features timely scratch detection and alert functions: by setting conductive elements 3 at key scratch-prone areas (lip 12 and curved side 11) of the handrail body 1, the circuit is quickly activated when in contact with a metal scraping object 5, causing the LED lights to illuminate. This visually alerts maintenance personnel to the scratching of the handrail, effectively preventing prolonged wear due to undetected scratches, extending the handrail's lifespan, reducing equipment maintenance costs and downtime, and ensuring the continuous and safe operation of escalators or moving walkways. The circuit design of this invention is reasonable: the LED lights include a battery and form a control circuit with the conductive elements 3. The structure is relatively simple and compact, requiring no complex external power supply or control wiring connections, facilitating integration into the special structure of the handrail. Battery power ensures continuous scratch detection and alert capabilities during equipment operation, unrestricted by external power sources, thus improving the system's autonomy and reliability.

[0029] Specifically, in this embodiment, the LED light group 2 includes an LED light 21 and a battery 22; the battery 22 is electrically connected to the LED light 21; the positive terminal 221 and the negative terminal 222 of the battery 22 are both electrically connected to the conductive element 3 through the wire 4.

[0030] Specifically, in this embodiment, the conductive element 3 includes a first electrode 31 and a second electrode 32; the first electrode 31 is electrically connected to the positive terminal 221 of the battery 22 via the wire 4; the second electrode 32 is connected to the negative terminal 222 of the LED lamp 21 and the battery 22 via the wire 4; when the lip 12 of the handrail body 1 or the arc-shaped side 11 of the handrail body 1 scratches the metal scraper 5, the first electrode 31 and the second electrode 32 are connected, and the LED lamp 21 is lit.

[0031] Specifically, in this embodiment, a conductive element 3 is provided on both the arc-shaped side 11 of the handrail body 1 and the lip 12 of the handrail body 1.

[0032] Specifically, in this embodiment, the conductive element 3 is made of a flexible conductive material to adapt to the deformation of the handrail belt. It should be noted that the advantages of flexible conductive materials are: the conductive element 3, made of a flexible conductive material, can well adapt to the bending, stretching, and other deformations of the handrail belt during operation, and will not be damaged or have its conductivity affected by the normal deformation of the handrail belt, ensuring the stability and durability of the scratch detection function, and further improving the applicability and durability of the entire device in practical application scenarios.

[0033] Specifically, in this embodiment, a buzzer is also provided on the handrail body 1. The buzzer is connected in parallel with the control circuit and is used to issue an audible alarm when a scratch occurs. It should be noted that this utility model has multiple reminder functions: in addition to the visual reminder from the LED lights, a buzzer connected in parallel with the control circuit is also provided. When a scratch occurs, an audible alarm can be issued simultaneously. In noisy environments or when maintenance personnel do not notice the visual reminders in time, the audible signal can effectively attract attention, enhancing the reminder effect and further reducing the risk of scratches not being addressed in a timely manner.

[0034] Specifically, in this embodiment, the battery 22 is a rechargeable battery, and the handrail body 1 is provided with a charging interface for convenient charging and maintenance of the battery. It should be noted that the rechargeable battery and charging interface: using a rechargeable battery and providing a charging interface on the handrail body 1 facilitates periodic charging and maintenance of the battery, reduces the frequency of battery replacement, lowers operating costs, and also conforms to the concept of energy conservation and environmental protection, making the entire handrail system with scratch warning more economical and sustainable in long-term operation.

[0035] Specifically, in this embodiment, the handrail body 1 includes a wear-resistant layer, a conductive layer, and an insulating layer. The wear-resistant layer is located on the outermost layer, and the conductive layer is located between the wear-resistant layer and the insulating layer. The conductive element 3 is embedded in the conductive layer to ensure that each component functions normally and does not interfere with each other. It should be noted that the handrail body 1 of this utility model adopts a layered structure design: the wear-resistant layer, conductive layer, and insulating layer of the handrail body 1 have a reasonable layered structure. The wear-resistant layer ensures the normal use function and appearance of the handrail, the insulating layer effectively prevents current leakage from causing safety hazards, and the conductive layer provides a stable implantation environment for the conductive element 3, ensuring its normal operation and non-interference. This layered design improves the overall functionality, safety, and stability of the handrail, and helps to improve product quality and market competitiveness.

[0036] The manufacturing and use process of this utility model is as follows: In manufacturing this handrail with scratch warning, the layered structure of the handrail body 1 is first constructed. A conductive element 3 is embedded in the conductive layer between the wear-resistant layer and the insulating layer, ensuring its position corresponds to easily scratched areas such as the curved side 11 and lip 12 of the handrail. Wires 4 are laid appropriately within the handrail body 1, connecting the conductive element 3 to the LED light assembly. The battery in the LED light assembly is installed on the flat part of the handrail body 1 and connected to the LED light, simultaneously forming a complete control circuit through the wires 4 and the conductive element 3. A buzzer is installed on the handrail body 1 and connected in parallel with the control circuit. A charging interface is provided in a suitable location for charging the rechargeable battery.

[0037] During normal use of the handrail, when the handrail is running normally without scratches, the conductive element 3 is in the open state, no current flows through the control circuit, the LED lights are off, and the buzzer does not sound. Once the lip 12 or curved side 11 of the handrail scratches against the metal object 5, the first electrode 31 and the second electrode 32 of the conductive element 3 contact the metal object 5 and become conductive. Current flows from the positive terminal of the battery through the wire 4, the conductive element 3, the LED lights, and then back to the negative terminal of the battery through the wire 4, forming a closed loop. The LED lights illuminate, and the buzzer sounds an alarm. Maintenance personnel can quickly locate the scratch location based on the light and sound cues and take timely measures to eliminate the potential scratch hazard, such as adjusting the relative position of the handrail and surrounding components, and removing foreign objects.

[0038] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
