Description

Technical Field

[0001] The utility model relates to the technical field of elevator light curtains, in particular to a fully waterproof elevator light curtain. Background Art

[0002] The elevator light curtain is a light-type elevator door safety protection device, which is suitable for passenger elevators and freight elevators to protect the safety of passengers. It consists of four parts: an infrared transmitter and receiver installed on both sides of the elevator car door, a power box installed on the top of the car, and a special flexible cable. There is an infrared transmitting tube in the transmitter. Under the control of the MCU, the transmitting and receiving tubes are opened in sequence, and the car door area is continuously scanned from top to bottom to form a dense infrared protection light curtain. When any beam of light is blocked, the control system immediately outputs a door opening signal, and the car door stops closing and reverses to open. The elevator door can only be closed normally after the passenger or the obstacle leaves the warning area, thereby achieving the purpose of safety protection, which can avoid the occurrence of elevator pinching accidents. In the prior art, the infrared transmitter is installed inside the light curtain housing, which is not only inconvenient to install, but also easily causes obstruction to the light emission during the installation process, thereby causing a malfunction during use and causing the protection to fail. In addition, the waterproof performance of the elevator light curtain in the prior art is poor, and it is easy to get water in during use, causing the light curtain to fail. Utility Model Content
