Description

Technical Field

[0001] This utility model relates to the field of elevator display screen technology, and in particular to an elevator display screen that is easy to maintain. Background Technology

[0002] Elevator floor displays, also known as elevator monitoring floor displays or elevator floor character overlay devices, are suitable for all types of elevators with elevator monitoring systems installed. Without altering the original electrical wiring of the elevator, they use photoelectric sensors to sample the elevator's operating status and can overlay and display information such as time, date, elevator name, floor, direction of travel, status, and floor-locking faults onto the remote elevator monitoring video.

[0003] Existing elevator car interior displays are often embedded inside the car shell or fixed with bolts or other mechanisms, making subsequent disassembly and maintenance inconvenient. Therefore, we propose an elevator display that is easier to maintain. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide an elevator display screen that is easy to maintain.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an elevator display screen that is easy to maintain, comprising an elevator car frame, an inner mounting groove, and a display component. The display component consists of a display frame, a display screen, and a circuit board. A controller is installed inside the inner mounting groove. An interface is provided on one side of the circuit board. A power cord is connected to one side of the controller. The power cord and the interface are plugged into each other. Two sets of mounting plates are installed on one edge of the display component. Rectangular grooves are provided at the top and bottom of the other side of the display frame. A paddle is provided inside the rectangular groove. A locking piece is installed above the paddle. Locking slots are provided on both the top and bottom sides of the inner mounting groove. A connecting shaft is installed inside the rectangular groove. The paddle is connected to the connecting shaft through a connecting hole. A spring connected to the paddle is provided inside the rectangular groove. A sealing gasket connected to the inside of the rectangular groove is covered and fitted on the outside of the paddle.

[0006] Preferably, when the latch on one side of the dialing element is engaged with the inside of the slot, the display component is in a locked mounting slot inside the elevator car frame. When the dialing element inside the rectangular slot is moved to press the spring, the latch on the dialing element is separated from the inside of the slot, and the display component is in a detachable state inside the mounting slot.

[0007] Preferably, the mounting groove has mating pieces installed on both sides, a magnetic piece is provided on one side of the mating piece, and a notch is provided at the edge of the mounting plate. A magnetic attractor is installed inside the notch, and both the magnetic piece and the magnetic attractor have magnetic properties.

[0008] Preferably, when the display component is inserted into the mounting groove inside the elevator car frame, the mounting plate on one side of the display component is engaged with the inner side of the mounting groove, and the magnetic attractor inside the mounting plate is magnetically attracted and fixed with the magnetic sheet on one side of the docking piece.

[0009] Preferably, a sealing gasket is provided at one edge of the display component, and the sealing gasket itself has deformation characteristics.

[0010] Preferably, when the display component is installed by docking with the inside of the mounting groove, the sealing gasket on one side of the display component is in a sealed fit with the surface of one side of the elevator car frame.

[0011] This utility model provides an elevator display screen that is easy to maintain. It has the following advantages:

[0012] 1. This elevator display screen is easy to maintain. In this paper, after the display component is installed and docked with the inner mounting groove, two sets of mounting plates on one side of the display component can be inserted into the inner mounting groove and docked with the docking piece. At the same time, the pushers inside the two sets of rectangular grooves are pushed to compress the springs, so that the locking pieces on the pushers can smoothly enter the inner mounting groove. When the display component docks with the side surface of the elevator car frame, when the two sets of pushers are released, the two sets of pushers can control the locking pieces to lock with the inside of the slots through the elastic reset of the springs, so that the display component can be quickly installed. Disassembly is the same. The magnetic components inside the mounting plates can be magnetically attracted and fixed with the magnetic pieces on the side of the docking piece, which helps to ensure the stability of the display component installation, thereby achieving the effect of conveniently and quickly disassembling, assembling, maintaining and using the display component.

[0013] 2. This elevator display screen is easy to maintain. A sealing gasket is provided on one edge of the display component. The sealing gasket itself has deformation characteristics. After the display component is installed by mating with the mounting plate and the inner groove of the mounting plate, as the display component is fixed by the clip on the latch and the slot, the sealing gasket on one side of the display component will be sealed and pressed against the surface of the elevator car frame, thereby improving the installation sealing of the display component and preventing dust penetration.
