Description

Technical Field

[0001] The utility model belongs to the technical field of elevator security equipment, and particularly relates to an elevator security alarm internal and external short-distance communicator. Background Technique

[0002] After the existing alarm fails, there are a large number of electronic components in its internal installation structure, which is not convenient for disassembly and repair. The "elevator communication alarm" disclosed in the application number "CN202321626847.1" is also an increasingly mature technology. By setting a limiting device, when quickly installing and limiting the alarm main body, the hexagon socket can drive the connecting turntable to rotate synchronously through the driving gear and the driven gear, so that the connecting turntable can be slidably limited by the limiting card shaft and the guiding slider, and then the four positioning card plates can be quickly and stably limited inside the fixed card slot, thus completing the limiting of the alarm main body and the connecting side plate, effectively improving the convenience of installation and disassembly of the device. However, this device still has the following defects: in actual use, when the elevator power is cut off, the internal lighting equipment cannot provide lighting, the visibility is low, it is not convenient for the user to press the emergency button to turn on the intercom and communicate with external personnel. At the same time, when a fire breaks out in the elevator, the trapped personnel inside cannot press the button, and external personnel cannot understand the situation inside the elevator. After the intercom is used for a long time, external dust easily enters the intercom and interferes with the internal electronic components, and the intercom is not convenient for disassembly and cleaning. Content of the Utility Model

[0012] In this scheme, after the elevator power is cut off, the fluorescent cover prompts the operator to press the emergency call button.

[0013] In the implementation scheme of an elevator security alarm internal and external short-distance communicator of the present utility model, a backup battery is provided at the bottom of the inner wall of the call box.

[0014] In this scheme, after a power outage, the backup battery provides power for each component, and the intercom can be used normally in the case of a power outage.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1) The provided fluorescent cover prompts the operator to press the emergency call button in the dark state. After a power outage, the backup battery provides power for each component, and the intercom can be used normally in the case of a power outage. When the user is unable to press the button, after the elevator catches fire, the internal smoke detector detects the smoke and transmits the signal to the intercom. The intercom automatically turns on the call mode, and at the same time, the wireless signal transceiver sends an alarm signal to the Internet of Things to notify the management personnel;

[0017] 2) The dust-proof filter screen in the provided filter box filters dust, preventing dust from entering the intercom and keeping the surface of the intercom clean. The filter box can be removed from the filter slot for cleaning, facilitating equipment maintenance. During the process of disassembling the maintenance board, press the top block, and the top block squeezes the spring pin to eject the spring pin from the L-shaped card slot, removing the maintenance board. The reset spring rebounds to reset the top block, facilitating the quick disassembly of the maintenance board for repairing the intercom. BRIEF DESCRIPTION OF THE DRAWINGS
