Description

Technical Field

[0001] The utility model relates to the technical field of warning sign devices, in particular to a portable intelligent elevator warning sign. Background Art

[0002] When an elevator is under maintenance, warning devices with construction warning signs need to be set at the construction site (such as the elevator door). For example, at the elevator door (or other construction sites), a warning sign or warning tape with a warning sign is used to enclose it. In the actual use process, since there is no one on-site for real-time maintenance, if the warning sign falls or the warning tape drops, it cannot play a good warning role; more importantly, in the actual use process, the warning sign or warning tape is often moved artificially. If the staff does not discover and correct it in time, it may cause people to accidentally enter the elevator door (or other construction sites) under construction. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model proposes a portable intelligent elevator warning sign, which can effectively enclose, and give a prompt when a person approaches the portable intelligent elevator warning sign or when the portable intelligent elevator warning sign is moved.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0013] Furthermore, a plurality of elastic buckles for limiting the movement of the pusher are arranged at intervals from top to bottom in the chute.

[0014] Furthermore, a power interface is also provided on the same side of the housing as the back of the warning sign body, and a charging protection circuit module is also integrated on the control circuit board;

[0015] The power interface is electrically connected to the power module through the charging protection circuit module.

[0016] Furthermore, an LED lamp is also provided on the front of the warning sign body; the LED lamp is electrically connected to the processor module.

[0017] Furthermore, a wireless communication module is also integrated on the control circuit board; the wireless communication module is electrically connected to the processor module.

[0018] Furthermore, a handle is provided on the warning sign body.

[0019] Furthermore, anti-slip pads are provided at the bottoms of the warning sign body, the support back plate and the support feet of the two telescopic support devices.

[0022] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are:

[0023] This portable elevator intelligent sign is convenient to use. When in use, open the support backboard, and then push the two telescopic support devices to extend through the pusher, and effective enclosure can be achieved. And through the two telescopic support devices, this portable elevator intelligent sign is placed more stably. And when in use, after turning on the control circuit board in the controller through the switch button, once the human body infrared sensor senses that someone is approaching, control the LED light to flash, and the buzzer emits a prompt sound to remind non-related personnel not to approach the construction site. At the same time, turn on the camera to collect surveillance videos, and transmit the surveillance videos to the background terminal through the wireless communication module.

[0024] Furthermore, by setting a proximity sensor in the storage groove of the warning sign body, when it is detected that the telescopic support device contracts into the corresponding storage groove, it is judged that this portable elevator intelligent sign is not in use, and the control circuit board of the controller is controlled to shut down intelligently to save electric energy.
