Description

Waterproof and dustproof wiring structure for elevator

The present invention relates to a wiring structure for elevators, in particular to a waterproof and dustproof wiring structure for elevators that effectively blocks foreign objects such as water droplets and dust.

At present, most of the elevators used to carry people and goods are controlled by automated equipment and do not require special personnel to operate. Passengers can press the floor button by themselves to reach the floor they want to go to. The use is quite simple.

Due to the heavy elevator door panels, in order to prevent the elevator from pinching passengers during the door closing process and causing personal injury, safety touch panels, photoelectric or light curtains and other anti-pinch devices are generally installed on the elevator doors. Among them, the safety touch panel is usually a mechanical anti-pinch device. When the elevator door is closed, if a person or object touches the safety touch panel, the safety touch panel will drive the rear micro switch to control the elevator door to open. Photoelectric is to install a light emitting end on one side of the elevator door and a light receiver end on the other side of the elevator door. When the elevator door is closed, if people or objects block the light, the light receiving end will not receive the light emitted by the light emitting end. Light source, the photoelectric will immediately drive the back-end controller to control the elevator to open the door. The operating principles of light curtains and optoelectronics are roughly the same. The difference is that the light emitting end and light receiving end of the light curtain are much denser and denser than the optoelectronics.

However, the above-mentioned photoelectric and light curtains are all photoelectric devices, which are not suitable for contacting foreign objects such as moisture, dust, particles, etc. However, the elevator is installed in the elevator shaft and cannot be completely waterproof and dustproof. In view of this, in order to ensure the normal operation of the elevator and give full play to the role of protecting personnel, the inventor of this case believes that it is necessary to conceive a technical solution that can improve the waterproof and dustproof effects of photovoltaic devices, light curtains and other photovoltaic devices for elevators, thereby reducing device damage Chances and ensure the safety of passengers.

The main purpose of the present invention is to provide an elevator line protection structure that effectively improves the waterproof and dustproof effect.

In order to achieve the above objective, the present invention provides a waterproof and dustproof wiring structure for elevators, which includes a hollow sleeve, a light blocking device, and a waterproof and dustproof cover. A filter plate is arranged on one side of the hollow sleeve. The light blocking device is arranged in the hollow sleeve and corresponds to the position of the filter plate. The waterproof and dustproof cover is arranged at the opening of the upper end of the hollow sleeve, the inner side of the waterproof and dustproof cover has a wiring channel, and a wiring opening is provided on one side of the hollow sleeve toward the lower end for the light blocking device The power line of the cable passes through the wiring channel and then passes through the wiring port after turning 180 degrees.

Further, the waterproof and dustproof cover is provided with a U-shaped groove corresponding to the position of the filter plate.

Further, one side of the waterproof and dustproof cover is provided with a tight fitting groove clamped on both sides of the hollow sleeve.

Further, two sides of the filter plate are respectively provided with a guide rail, one side of the hollow sleeve where the filter plate is provided has a side opening, and two opposite sides of the side opening are respectively provided with a corresponding sliding channel combined with the guide rail.

Further, the hollow sleeve further includes an extension plate arranged on a side opposite to the filter plate.

Further, the inner side wall of the waterproof and dustproof cover is provided with a positioning bar, and the outer side wall of the hollow sleeve is provided with a slot corresponding to and combined with the positioning bar.
